AMD throws shade at Nvidia RTX 4080 while boasting

AMD talked about its upcoming RDNA 3 graphics cards while casting some shade on Nvidia's impending RTX 4080 GPU.

This is all part of a bunch of introductory material on AMD Advantage PCs and their various advantages, which are systems that use the latest Ryzen processors and RDNA 3 GPUs to great effect, as noted by Tom's Hardware (Opens in a new tab ) (via Wccftech - opens in a new tab)).

The really interesting bits are around the GPUs, which are AMD's incoming RX 7900 XT and 7900 XTX, and they stack up against the RTX 4080 in terms of base specs. The presentation slides show that the 7900 XTX is loaded with 24GB of VRAM and the 7900 XT with 20GB, compared to 16GB for the RTX 4080, and that the respective memory buses are faster at 384-bit and 320. bits, compared to 256 bits. for Nvidia card.

AMD also highlights the raw computing power of the 7900 XTX at 61 TFlops with the 7900XT at 52 TFlops, compared to 49 TFlops for the RTX 4080. (This metric doesn't mean much to gamers.) And Team Red reminds us of DisplayPort 2.1 support for their next-gen cards (with DP 1.4 for newer Nvidia models).

Another slide details a size comparison of the 7900 XTX vs. the 4080, showing the AMD model as a 2,5-slot vs. 3-slot affair, and the Team Red card is a bit shorter as well (287mm vs. 304mm).

And, unsurprisingly, AMD points out that the 7900 XTX only requires 2 x 8-pin power connectors, unlike the adapter configuration the 4080 works with (which caused some controversy with the RTX 4090 as described). we see). reported incidents of adapter cable fusion).

While AMD isn't doing any direct performance comparisons to the RTX 4080 as such, although that is likely to happen in the future, Team Red offers benchmarks that show the new 7900 XTX outperforms the previous flagship 6950 XT by up to 67% at raster frame rates (no ray tracing, in other words).

This includes the 7900 XTX hitting 139 frames per second (fps) at 4K resolution (maximum detail settings) in Call of Duty: Modern Warfare 2, compared to 92 fps on the 6950 XT. And in Cyberpunk 2077, the gap was 72 fps vs. 43 fps.

Performance increased even more with ray-traced games, and in fact, AMD saw an increase of up to 82% in this case for the new RDNA 3 card.

Analysis: Targeting the RTX 4080 in simple words(*3*)

Naturally, all of this should be viewed with some skepticism, as carefully selected references will always be used for promotional material such as this; that's to be expected, whether it's AMD, Nvidia, or anyone else.

Still, it's pretty clear that AMD is definitely targeting the RTX 4080 when it comes to its RDNA 3 top dogs, though incoming graphics cards are still a long way off. While the RTX 4080 arrives tomorrow, the 7900 XTX and 7900 XT won't debut until December 13, still almost a month from now.

That said, we don't know how much stock of the RTX 4080 we'll see, as starting prices on the eve of launch seem slim, and what we've glimpsed from those pre-launch price tags is that they're worryingly stacked in some cases (outside of the USA, anyway). This could give AMD a huge advantage in terms of being able to keep that price lower than the 4080, assuming the RDNA 3 graphics cards appear in large enough volume and are therefore not subject to inflation via resellers.

All of that to say, it's really conjecture as to how this next-gen GPU battle will play out in late 2022, but for now, AMD seems ready to take some chunks out of Nvidia.
