AMD’s new Radeon RX 6800 XT promises to go head to head with Nvidia’s RTX 3080 – The Verge

Published

 on


AMD is introducing three new Radeon RX 6000 Series graphics cards today that will take on Nvidia’s latest RTX 3000 Series of GPUs. There’s the Radeon RX 6800 XT ($649), which goes up against the RTX 3080; the Radeon RX 6800 ($579), which can be compared to the RTX 2080 Ti or RTX 3070; and finally the Radeon RX 6900 XT ($999), which is pitted against Nvidia’s giant RTX 3090.

All three are based on AMD’s latest RDNA 2 technology that’s also found inside the PS5 and Xbox Series X. These latest Radeon cards will support hardware-accelerated ray tracing for next-gen games, and AMD is promising to go head to head with Nvidia in 4K and 1440p PC gaming.

The new $649 Radeon RX 6800 XT is aimed at Nvidia’s RTX 3080 specifically, promising performance in 4K and 1440p gaming that matches or exceeds Nvidia’s latest card for $50 less. It comes equipped with 16GB of GDDR6 memory, a 2015Mhz base clock, 2250Mhz boost clock, 20.74 teraflops of GPU performance, and 72 compute units overall.

AMD has shared some early benchmarks that show the Radeon RX 6800 XT beating the RTX 3080 at 4K in Battlefield V, Borderlands 3, Call of Duty: Modern Warfare, Forza Horizon 4, and more. It also matches the RTX 3080 in Shadow of the Tomb Raider, Gears 5, and Doom Eternal. If these results are similar across a wider range of games, then the Radeon RX 6800 XT certainly looks promising for solid 4K gaming performance.

AMD’s own benchmarks are also similar at 1440p, with the same games tested. We’ll obviously need to test this card fully against the RTX 3080, but it looks like AMD has managed to match or beat Nvidia’s latest GPU in a number of games. AMD has achieved these performance improvements while keeping the power draw less than Nvidia’s RTX 3080. The RX 6800 XT draws up to 300 watts of power, while the RTX 3080 draws up to 320 watts.

Next up is the $579 Radeon RX 6800, which is aiming for Nvidia’s RTX 2080 Ti. According to AMD, it beats or matches Nvidia’s older card in the limited number of games that the company has tested in both 4K and 1440p. It comes equipped with 60 compute units, a 1815Mhz base clock, 2105Mhz boost clock, 16.17 teraflops of GPU performance, and 16GB of GDDR6 memory.

Interestingly, the base 6800 draws 250 watts of power, just 10 watts less than Nvidia’s own RTX 2080 Ti Founders Edition. AMD hasn’t shared benchmarks against the new RTX 3070, but if it can also match or exceed Nvidia’s latest $499 card, then it might just be another great option for 1440p.

Finally, there’s the $999 RX 6900 XT, which goes head to head with Nvidia’s RTX 3090. While Nvidia has positioned the RTX 3090 for 8K gaming, its large 24GB of memory makes it more likely to be used by the creative industry as a Titan replacement. AMD hasn’t opted to bump the memory on its equivalent, keeping the RX 6900 XT at 16GB of GDDR6 memory and offering a competitive price as a result.

AMD has bumped up its compute units to 80 in total here, but the core clock remains at 2015Mhz with a boost of 2250Mhz. This all results in 23.04 teraflops of GPU performance. The performance against the RTX 3090 looks a lot more mixed from AMD’s own benchmarks. While the RX 6900 XT promises to comfortably beat the RTX 3090 in Battlefield V, Forza Horizon 4, and Gears 5, it loses out or just matches in other titles.

All three new Radeon RX 6000 Series cards also use a traditional 2.5 slot design, with regular PCIe connections and a triple-fan system that cools the cards. AMD hasn’t done any fancy work to shrink its PCB like Nvidia has, nor is it introducing a new 12-pin power connector.

You’ll notice that AMD has opted for 16GB of GDDR6 memory in all three of its new Radeon cards. That’s more than what’s available on the RTX 3070 (8GB) and RTX 3080 (10GB) but less than the 24GB found on the RTX 3090. Both Nvidia’s RTX 3080 and 3090 cards also use faster GDDR6X modules, but AMD opted to avoid the move to more expensive and more power-hungry high-speed modules.

Instead, the company is aiming for efficiency improvements with a new Infinity Cache design. Infinity Cache is the biggest part of AMD’s memory improvements here. Gaming at 4K can often be limited by memory bandwidth in modern GPUs, and AMD is hoping to answer some of these demands with a bigger, more capable cache instead of higher-speed GDDR6X.

AMD is using a high-speed 128MB cache that’s based on the company’s Zen 3 L3 CPU cache design. It’s optimized for graphics use and promises to deliver twice the bandwidth. What this all means is that these latest Radeon cards can more efficiently feed data to the graphics pipeline and provide performance improvements without significant increases to power draw. AMD’s goal here was to double the performance from its previous RX 5700 XT card with only a slight bump to power draw.

Because these cards are all RDNA 2, that means they support Microsoft’s DirectX12 Ultimate APIs and even DirectStorage once it’s available. This includes hardware-accelerated ray tracing and variable rate shading. Once DirectStorage is fully enabled in Windows at some point in 2021, load times on certain NVMe drives will be reduced further. AMD also has a “rage mode” for easy and stable overclocking on these cards. It will be interesting to see how much extra performance can be squeezed out of these supposedly efficient cards.

While AMD is promising to go head to head with Nvidia in 4K gaming and more, the one big missing piece of this battle is a lack of an equivalent to Nvidia’s DLSS. Nvidia’s AI-powered super sampling technology has been transformative for the games that support it, bringing great image quality and higher frame rates by simply toggling a game setting.

AMD tells me it has a new super sampling feature in testing, which is designed to increase performance during ray tracing. The company is promising its super sampling technology will be open and cross-platform, which means it could come to next-gen consoles like the Xbox Series X and PS5. AMD is working with a number of partners on this technology, and it’s expecting strong industry support. Unfortunately, this won’t be ready for the launch of these three new Radeon RX 6000 Series cards.

Both the Radeon RX 6800 XT and RX 6800 will go on sale on November 18th, with the Radeon RX 6900 XT hitting stores on December 8th. While AMD hasn’t been able to match or beat Nvidia’s pricing for the RTX 3070, the $50 saving on the RX 6800 XT vs. the RTX 3080 could be significant. It will all depend on whether AMD’s performance promises measure up to Nvidia’s latest cards, as they could offer a great alternative for people looking to upgrade their GPUs in the coming months. Hopefully AMD will be able to supply enough stock for the inevitable demand.

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.”

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. ®
