Nvidia GeForce RTX 4080 16GB Founders Edition Review – IGN

Published

 on


Following last month’s launch of the $1,599 Nvidia GeForce RTX 4090, a graphics card meant largely for professional use, today the new generation of GPUs has finally arrived for the slightly less wealthy crowd of PC gamers in the form of the Nvidia GeForce RTX 4080 16GB Founders Edition, which launches tomorrow for $1,199. That means the entry point for the RTX 40-series’ lofty performance claims and frame-generating DLSS 3 has come down at least a bit. We’re still at the beginning of this new GPU generation, but so far the RTX 4080 is a strong showing.

What’s in a Name

Before we get to the spec sheet and performance numbers, we should cover the RTX 4080 naming kerfuffle and talk a bit about how Nvidia’s GPUs are typically positioned – and why this generation is a bit different than years previous. Dating back more than a decade, Nvidia GPUs bearing the “-80” moniker are considered the flagship mainstream cards, and have been priced in the $500 to $700 range. Looking more specifically at recent trends, the GTX 1080 launched at $599, and both the RTX 2080 and 3080 launched at $699.

300x250x1

You might be wondering, then, why the RTX 4080 starts at nearly double that range. The answer is in that aforementioned naming fiasco. Originally, Nvidia planned two variants of the RTX 4080 – a 16GB for $1,199 (the version we’re reviewing here) and a 12GB, priced at $899. This wouldn’t have been the first time Nvidia has launched VRAM-variant cards, but typically the amount of VRAM was the only difference, whereas in this case the two cards also carried different core counts and clockspeeds – differences that previously would have warranted a bump down to another tier (in this case, the RTX 4070).

People rightfully complained about the confusion this was already starting to cause, and to Nvidia’s credit it responded, opting to “unlaunch” the RTX 4080 12GB; it’s now rumored that those cards will be re-announced with the “RTX 4070 Ti” name, though as of yet there’s nothing official.

That’s all well and good, but it still leaves us with a “mainstream” card bearing the enthusiast-tier pricing that would previously have been reserved for a card bearing the “Ti” label – representing a mid-generation step up. In other words, typical generational comparisons are a bit skewed this time around, so we’ll mostly be comparing the RTX 4080 against the RTX 3080 Ti, which also launched at $1,199 in June 2021, as opposed to the RTX 3080.

Nvidia GeForce RTX 4080 – Design and Features

If you read my review of the RTX 4090, you’ll remember that it’s an absolutely massive card, in both size and performance terms. The RTX 4080, meanwhile, is…not any smaller. It bears the same triple-slot designation, measuring 11.9 inches (304mm) long, 5.4 inches (137mm) wide, and 2.4 inches (61mm) thick – the exact same dimensions as the RTX 4090. This is a big card. For comparison, the RTX 3080 measured 11.2 inches (285mm) long, 4.4 inches (112mm) wide, and 1.5 inches (40mm) thick, while the RTX 2080 and GTX 1080 were even smaller.

Most of that heft comes from the large, dual-axial flowthrough cooling solution required to keep temperatures in check. The cooler design is mostly similar to that of the RTX 3090, but with larger fans and taller fins in order to achieve what Nvidia says is 15% more airflow at the same acoustic level. In practice, the RTX 4080 remained whisper-quiet while keeping temperatures hovering around 53-55C, with a peak of 57C, during a long stretch of benchmarking.

Compared to the RTX 3080 Ti, the RTX 4080 has 9,728 CUDA cores (down from 10,240), 304 fourth-gen Tensor cores (vs 320 third-gen), and 76 third-gen RT cores (vs 80 second-gen). In other words: it has newer cores, but slightly fewer of them overall. The decrease in count shouldn’t be alarming though, since the 4080 includes a boost clock speed of 2,505MHz compared to the RTX 3080 Ti’s 1,665MHz clock, not to mention the 16GB of GDDR6X VRAM, compared to 12GB on its 30-series “predecessor.”

Like the RTX 4090, the 4080 uses the somewhat contentious 16-pin 12VHPWR power connector that has recently been in the news due to reports of it overheating and melting. We haven’t had any issues with it in any of our testing, but we’ll definitely be monitoring the situation as this generation of graphics cards matures.

Speaking of power, the RTX 4080 has a TDP of 320W, down from 350W on the RTX 3080 Ti. Nvidia recommends using a 750W power supply at minimum. There’s also a 3x 8-pin adapter in the box for people whose power supplies don’t have the new connector.

For ports, the RTX 4080 has 3x DisplayPort 1.4a and 1x HDMI 2.1a. This is the typical layout for current-gen graphics cards, though AMD’s recently-announced RX 7900 XT and XTX use the newer DisplayPort 2.1, which has more than triple the bandwidth and enables 4K resolution at up to 480Hz, or 8K up to 165Hz, versus 240Hz at 4K and 60Hz at 8K for DisplayPort 1.4. Most games and monitors won’t be able to take advantage of that bandwidth, so it’s sort of a moot point, but AMD does technically have the advantage.

Nvidia Geforce RTX 4080 – Performance

Starting off with our synthetic benchmarks, the RTX 4080 comes out swinging in 3D Mark Fire Strike Ultra with a 17% improvement over the RTX 3090 Ti and 28% over AMD’s RX 3950 XT – the two best GPUs of the previous generation – and a 35% boost over its generational price-equivalent predecessor, the RTX 3080 Ti. As you’d expect it falls considerably short of the RTX 4090, however, with a score of 16,255 compared to the RTX 4090’s 21,872, which makes total sense given that card costs $400 more.

Moving on to Unigine Heaven, the RTX 4080 edges out the RTX 3090 Ti and RX 6950 XT at 1080p and 1440p, but actually falls short of both cards at 4K. Against the RTX 3080 Ti, though, it consistently wins out with a 13% lead at 1080p, 14% at 1440p, and a slight 4% at 4K.

The ray tracing synthetics are more dramatic. The RTX 4080 offers an average uplift of 28% compared to the RTX 3090 Ti across our three tests, and of course absolutely demolishes the RX 6950 XT, which lacks the ray tracing chops of Nvidia’s hardware. Comparing it to the 3080 Ti offers even more impressive results, with an average improvement of 45% compared to that card.

Moving on to our gaming benchmarks, the RTX 4080 again has a strong showing across all three resolutions tested. At this point our benchmark tests are basically CPU bound at 1080p, with the RTX 4080 pinging the meter alongside the more powerful RTX 4090. 1440p is relatively similar, with the card showing large gains over the last generation in tests that aren’t CPU bound, and of course matching the best in tests that are.

Nvidia GeForce RTX 4080 16GB Founders Edition – Gaming Benchmarks

Given the high-end nature of this hardware, however, the real story is at 4K. (If you’re not playing at 4K or greater resolutions, you shouldn’t spend this much money on a GPU.) Expanding our test suite slightly, you can see that the RTX 4080 offers considerable gains over the previous generation, with an average improvement of 27% over the RTX 3090 Ti and 45% versus the RTX 3080 Ti. Keep in mind that the latter of those cards launched at the same $1,199 price, while the former carried a $2,000 MSRP when it launched earlier this year (though prices have now fallen to around what you should expect to pay for an RTX 4080 fresh off the shelf).

Those are impressive gains, but not really out of the ordinary when you consider this is a new graphics generation. Looking back to our RTX 3080 review, that card offered 50% to 70% improvements over its generational predecessor, the RTX 2080 Super. That’s not to discount the RTX 4080 – 4K framerates well above 60fps in the most demanding games will raise eyebrows for a few years to come – I just feel it’s important to remember that we’re talking about high-end, if not enthusiast-level pricing here, so my expectations are sky high.

Finally, I want to touch on Nvidia’s new DLSS 3 frame generation technology. Check out my RTX 4090 review for a more in-depth explanation, but in short the GPU looks at two sequential frames, calculates the difference between them, and then uses AI to generate a frame in between them. As with the RTX 4090, I tested DLSS 3 and frame generation in Cyberpunk 2077.

DLSS again offered a stunning uplift, bringing the RTX 4080’s framerate up to 73 without frame generation, and 108 with it. Those are awesome numbers for one of the most technically demanding games available on PC today – and remember, this benchmark is run at 4K with max settings and ray tracing enabled. The 30-series RTX cards, meanwhile, both receive less of an uplift from DLSS, and don’t have access to frame generation all together.

Of course, DLSS 3 is still a new technology, and game support is limited for the time being. That said, it’s steadily rolling out to more games, including Microsoft Flight Simulator, A Plague Tale: Requiem, and Marvel’s Spider-Man Remastered. If support continues to grow as expected and the performance uplift remains as formidable, DLSS 3 will be the killer feature that truly makes upgrading to a 40-series card worth it for high-resolution, high-framerate gaming.

Nothing Ear And Nothing Ear (a) Earbuds Are 1st With ChatGPT Integration – Forbes

Published

 on


London-based Nothing Tech has just launched new earbuds, two pairs, in fact. The Nothing Ear and more affordable Nothing Ear (a) have just gone on sale—you can read Forbes contributor Mark Sparrow’s review of both pairs here. And now, the company has announced a cool new feature: and industry-first integration with ChatGPT. It comes with strings, though.

The new earbuds have just been announced and are available to pre-order from nothing.tech now and go on sale from Monday, April 22. If you’re in London, and you want to be among the very first to get the earbuds, you can snap them up in the Nothing Store Soho a little bit sooner, from Saturday, April 20 (click-and-collect is available).

From launch, the company said, “it will enhance its overall user experience with industry-first ChatGPT integrations in its audio and smartphone products.”

300x250x1

Nothing goes on that it wants “to advance consumer tech products’ transition to AI, as well as simplify and enhance the user experience.”

It means users will be able to pinch the earbud to directly speak to ChatGPT to ask questions and hear responses in the earbuds. Nothing is also introducing new elements to Nothing phones, such as widgets which make it easy to talk to ChatGPT on the handsets. Other features include being able to send screenshots directly to ChatGPT and a clipboard shortcut for sending text.

So, what are the catches?

Although the Bluetooth new earbuds will work with any iPhone or Android phone, and there are dedicated Nothing apps for each platform, the ChatGPT integration is more limited for now.

)();

The earbuds must be paired with a Nothing handset. From today, the feature works with the premium model, the Nothing Phone (2), providing it’s running the latest software. The earlier Nothing Phone (1) and more recent, more affordable model, Nothing Phone (2a) will need to wait for a software update, which Nothing says is “coming soon”.

Also coming in the future is compatibility with earlier Nothing earbuds, that is the Ear (1), Ear (2) and Ear (Stick).

The new earbuds are very keenly priced. Ear costs $149 (£129 in the U.K.), while Ear (a) is $99 (£99 in the U.K.). Both pairs have active noise-cancelling, which is not commonplace at this price point. The more expensive Ear has a wireless charging case and a feature to create a personal sound profile. Both pairs come in black and white finishes, with Nothing’s trademark transparent design in the earbuds and charging case. But the Nothing Ear (a) has an eye-catching extra: a tremendous yellow-finish option.

U of T Engineering PhD student is working to improve the sustainable treatment of Ontario's drinking water – U of T Engineering News – U of T Engineering News

Published

 on


Growing up in a small neighbourhood in Cameroon, Maeva Che (CivMin PhD student) was aware of challenges of accessing clean drinking water. 

“Experiencing that exposure to water issues and challenges with sustainable access to safe drinking water ignited my interest in water treatment,” Che says.  

Che’s drive to improve water quality around the globe brought her to the Drinking Water Research Group (DWRG) at University of Toronto’s Faculty of Applied Science & Engineering, where she is researching innovative solutions to address local water issues.  

300x250x1

Che is working under the supervision of Professor Ron Hofmann (CivMin), who is a member of the DWRG. Her research focuses on removing unpleasant taste and odour compounds in Ontario’s drinking water by promoting the biodegradation of these compounds through granular activated carbon (GAC) filtration. 

The project is supported by a five-year Natural Sciences and Engineering Research Council of Canada (NSERC) Alliance grant called Advanced and Emerging Issues in Drinking Water Treatment. 

GAC filtration is a water treatment process that uses granular activated carbon, which is made from organic materials that are high in carbon, such as wood, coal or coconut shells. These materials are heated in the absence of oxygen through a process known as pyrolysis and prompted chemically or physically to produce the activated carbon. The activation enhances the material’s adsorption properties, making it productive to remove contaminants from water.  

While GAC filtration is an effective treatment process, its adsorptive capacity is limited. The adsorptive capacity of GAC is expected to become exhausted after about three years in service and drinking water treatment utilities must replace the GAC. Aside from the inconvenience, replacing GAC is costly.  

Che is working on alternative ways to remove contaminants using GAC filtration, specifically through biodegradation. When the filtration has been in service for a while, there is the growth of micro-organisms on the GAC, which can be useful for removing contaminants.

“Think of biodegradation as the useful bacteria on the GAC feeding on the contaminants in the water, thereby removing them,” says Che. 

“If the GAC has enough good bacteria that is biodegrading the compounds, the GAC may not need to be replaced when its adsorptive capacity becomes exhausted. This can extend the filter’s lifetime, resulting in cost benefits for treatment utilities.” 

In other words, biodegradation can potentially enhance the performance of GAC filters. 

Che and the DWRG will collaborate with water treatment plants to determine methods that can enhance the biodegradation of taste and odour compounds within their GAC filters.  

Currently in its initial phase, the project is taking place alongside the Peterborough Utilities Group’s drinking water treatment plant, where Che is conducting pilot-scale filtration studies with support from the Peterborough Utilities Commission. They plan to extend this research to other partner treatment plants in the future. 

Working with various water treatment plants across Ontario, Che will also assess the effectiveness of GAC filters in removing non-traditional taste and odour compounds, which are not commonly monitored. 

To achieve this, she’ll evaluate filter performance for two common taste and odour compounds — 2-methylisoborneal and geosmin — and eight additional non-traditional compounds that can cause taste and odour events. This involves collecting GAC and water samples from the plants and conducting lab-scale filtration tests, called minicolumn tests. This test, developed by the DWRG, allows to differentiate between adsorption and biodegradation in GAC filters. 

Minicolumn tests provide crucial insights into the performance of the GAC filters in terms of the adsorption and biodegradation of contaminants. To distinguish between these mechanisms, researchers use parallel minicolumns. One minicolumn operates under conditions where the biological activity of micro-organisms is suppressed, which isolates the adsorption process. The second minicolumn operates without biological suppression, allowing both adsorption and biodegradation to occur. 

“Many plants are unaware of their filters’ performance for other compounds, aside from the two common ones, that also contribute to taste and odour events in water. Our project, therefore, plays a crucial role in expanding the understanding of this,” Che says. 

Project partners include the Ajax Water Supply Plant and the Barrie Surface Water Treatment Plant.  

The DWRG is made of approximately 30 graduate students, post-doctoral fellows, research managers and associates who collaborate with local, national and international industry and government organizations to address a wide range of projects related to municipal drinking water. 

Che credits her experience as a master’s student with the research group as a major factor in her decision to pursue a PhD at the University of Toronto.  

“During my master’s degree with the DWRG, I worked on projects that improved drinking water quality, gaining hands-on experience at treatment plants. Seeing the results of my research reinforced my decision to pursue my PhD here,” Che says. 

Ultimately, Che hopes to make a significant impact in the field — and the DWRG provides opportunities to achieve this, with a supportive community of researchers and supervisors.  

“My goal is to continue researching and developing sustainable solutions for drinking water treatment that benefit communities in need,” she says.

Huawei's latest flagship smartphone contains no world-shaking silicon surprises – The Register

Published

 on


When Huawei debuted its Mate 60 smartphone in mid-2023, it turned heads around the world after teardown artists found it contained a system-on-chip manufactured by Chinese chipmaker Semiconductor Manufacturing International Corporation (SMIC) using a 7nm process.

SMIC was thought not to be able to build that sort of thing. So while the Mate 60 didn’t differ markedly from every other modern smartphone, its very existence called into question the effectiveness of US-led efforts to prevent advanced chipmaking tech reach the Middle Kingdom.

Much speculation has therefore concerned what Huawei would deliver next, and this week the world got its answer – in the form of the Pura 70.

300x250x1

Chinese media report that early users of the device have posted details of its innards, naming the SoC as Kirin 9010 with four efficient cores running at 1.55GHz, half a dozen performance cores at 2.18GHz, and a couple of high-performance cores zipping along at 2.30GHz. All cores are Arm v8. A third-party spec sheet suggests it’s a 7nm chip – meaning Chinese chipmakers appear not to have made another unexpected advance.

Early tests suggest it outperforms the Kirin 9000 found in the Mate 60, but independent assessments are yet to emerge. The crowdsourced evaluations currently available are sometimes dubious.

What we can say with confidence is that the Pura 70 has a 6.6-inch OLED display with 120Hz refresh rate and resolution of 2,760 x 1,256. It has 12GB RAM aboard, and buyers can choose from 256GB, 512GB, or 1TB of storage.

The three rear-facing cameras on the base models can capture 50, 12, and 13 megapixels apiece.

The Pura range derives from Huawei’s P-Series handsets that stretched from the midrange to the low-end of premium, but are now focussed – pardon the pun – on photography enthusiasts. The device comes on four variants, each priced to match the four editions of Apple’s iPhone 15.

The screen on the high-end “Ultra” model grows to 6.8 inches and 2,844 × 1,260 pixels, with two rear cameras that shoot at 50 megapixels and one at 40. One of the 50MP snappers is retractable, to enhance its zooming powers.

Importantly, all models of the Pura 70 run HarmonyOS 4.2 – Huawei’s not-Android operating system.

China is all-in on HarmonyOS as the nation pursues indigenous alternatives to Western tech. In recent weeks Chinese media and government agencies have noted the growing proliferation of native HarmonyOS apps, trumpeting that developer enthusiasm for the platform means local buyers now have a more patriotic alternative.

That alternative appears to be welcome: after the debut of the Mate 60, analyst firm IDC saw Huawei’s smartphone market share improve by 36.2 percent. ®
