AMD's Vega architecture to pack power, performance in a tiny package

At the AMD Tech Summit in Beijing this weekend, AMD vice president Scott Herkelman took the stage to discuss the upcoming Vega-powered graphics cards. While we didn’t get a release date, Herkelman did discuss AMD’s plans to stay competitive in the notebook GPU market.

According to VideoCardz, AMD plans to decrease the overall footprint of the upcoming mobile GPUs by stacking VRAM dies and freeing up more internal space without sacrificing performance. Size is an important consideration for notebook manufacturers, but this announcement was light on details.

It’s unclear whether or not AMD’s new Vega architecture will be rolled out to discrete mobile GPUs — the kind found in premium and gaming-oriented systems — or if it will be included in AMD’s “APUs” — a CPU/GPU combo that delivers a smaller overall footprint but a lot less graphical performance.

Herkelman did mention that AMD hopes the new Vega-powered mobile chips will provide notebook manufacturers with the horsepower they’ll need for their products to drive virtual reality and “the latest and greatest AAA games,” which strongly suggests that we’ll see discrete GPUs powered by the new Vega architecture. It’s unlikely even a next-gen onboard GPU would have the headroom necessary to drive any but the least demanding VR experiences.

AMD’s previous architecture, code-named “Fiji,” never made a big splash in the notebook market, in part due to its overwhelming power demands. But Nvidia has had some success bringing the full-fat versions of its 10-series GPUs to notebooks despite their power consumption, indicating that there is a strong appetite for nearly desktop-grade graphical performance even if it impacts battery life.

Additionally, it appears that AMD’s Vega-powered GPUs will be available in 4GB and 8GB options, on account of the way the new chips will stack memory. Unfortunately, Herkelman didn’t offer a concrete timeline for when we might see those desktop and mobile GPUs hit the market, but reassured the Beijing audience that Vega-powered chips were “just around the corner.”

Security or performance? With this AMD vulnerability, you can’t have both
Render of an AMD Ryzen chip.

Recently, a cybersecurity researcher discovered a dangerous vulnerability within AMD's Zen 2 processors. Dubbed "Zenbleed," the vulnerability allows attackers to gain access to your computer and steal all of the most sensitive information, including passwords and encryption keys. While this doesn't affect AMD's best processors, it's still a dangerous vulnerability with a wide reach, as it's present in all Zen 2 CPUs, including consumer chips and data center EPYC processors. AMD has a fix on the way, but it might come at a price.

The bug was first spotted by Tavis Ormandy, a researcher working with Google Information Security, who made it public at the end of July. Since then, the researcher has also released a proof of concept code that shows how it works. This, while useful, might help attackers exploit this vulnerability until AMD comes up with a fix.

I tested AMD’s RX 7800 XT against Nvidia’s RTX 4070, and there’s a clear winner
AMD logo on the RX 7800 XT graphics card.

With the release of the Radeon RX 7800 XT and RX 7700 XT, AMD finally set foot in the mainstream gaming sector with its RDNA 3 lineup. Nvidia, its biggest rival, which also makes some of the best graphics cards, was the first to release competing cards with similar performance -- at least on paper. But are Nvidia's options better than AMD's in this generation?

The RX 7800 XT was, from the get-go, said to be the competitor to Nvidia's RTX 4070, but in reality, these GPUs differ both in price and performance. We've tested the RX 7800 XT and compared it to the RTX 4070, and we now know which of these two GPUs is the one to pick.

AMD FSR (FidelityFX Super Resolution): everything you need to know
amd radeon rx 6700 xt 12gb gddr6 vram

AMD's FidelityFX Super Resolution (FSR) is a supersampling feature available in a large swath of games. It has a simple goal: improving gaming performance on the best graphics cards. To help you understand how it works and why you should turn it on in your games, we rounded up everything you need to know about AMD FSR, including the newly announced FSR 3.

It works by rendering your game at a lower resolution, but the magic of FSR comes in the upscaling. It attempts to fill in missing details to make your game look like it's running at native resolution, just with a massive boost in performance. Here's all you need to know about it.
