In terms of performance, the AMD Radeon RX 6600 XT is equivalent to the Nvidia GeForce RTX 3060. How much cache and memory does the AMD Radeon RX 6600 XT have? Next we have Metro Exodus Enhanced and this version of the game requires ray traced accelerated hardware, so ray tracing effects are enabled by default and for testing these mid-range GPUs we've gone with the 'normal' setting. Typically, Radeon GPUs perform well in the F1 series, but F1 2021 enables ray tracing by default at the highest presets and therefore we tested with the feature enabled. This hands the RTX 3060 a performance advantage, affording it a 6% performance advantage at 1080p and 10% at 1440p. Disabling ray tracing does favor the 6600 XT, but we feel we might as well test using the default configuration as that's how we normally test, and we're still looking at around 60 fps at 1440p.
Assuming you don't run into CPU bound conditions, Radeon and GeForce GPUs scale very similarly with the quality presets, so using competitive settings both the 6600 XT and RTX 3060 will deliver a similar level of performance. The Rainbow Six Extraction performance was comparable with both GPUs delivering over 130 fps at 1080p. The RTX 3060 did edge ahead by a 7% margin at 1440p, but overall performance was very similar. We're still more concerned with the 128-bit memory interface, though. That gives the RX 6600 XT exactly half the bandwidth and memory of the RX 6800 XT, with a quarter of the L3 cache. Will that mean half the performance as well? And what does that look like against competing GPUs from both Nvidia and AMD — and not just current generation cards, but also the previous generation? Another potential issue is that AMD has gimped the PCI Express interface and although it still uses PCIe 4.0, the bandwidth has been reduced to x8. When installed in a PCIe 4.0 system this is a non-issue, but performance related problems could arise when installed in a system that only supports PCIe 3.0, which right now is most systems. Put differently, the Radeon 6600 XT is 21% cheaper than the 6700 XT and on paper it appears it's going to be at least 20% slower.At 1080p we see that the margin has decreased from 10% in favor of the Radeon GPU to just 6%, not a massive change but it's certainly less favorable for AMD. The decline is largely due to the inclusion of titles such as PUBG, Days Gone, Flight Simulator 2020, Warhammer II, Biomutant, and F1 2021. As expected the margins continue to head in the wrong direction for the 6600 XT when increasing the resolution. At 1440p it's now 18% slower than the 3060 Ti and 24% slower than the 6700 XT. And it's not as if certain workloads, which despite everything many of these will no doubt find themselves partaking in, is really all that demanding of VRAM or PCIe bandwidth at all. Next we have Call of Duty Warzone, where the 6600 XT was quite a bit faster than the RTX 3060, delivering 21% more frames at 1080p and 16% more at 1440p. A strong win for the Radeon GPU, though keep in mind it was also meant to cost 15% more based on the original MSRP.
Not expecting much out of this one.Given no graphics cards are restricted by the PCI-E 3 x16 bandwidth, PCI-E 4 support offers no advantage. There were just a handful of outliers where the margins extended to 10% or more in either direction. The big losses for AMD were seen in Resident Evil Village and Metro Exodus Enhanced Edition, unsurprisingly two of the games that used ray tracing. Vermintide 2, God of War, and PUBG were also bad titles for AMD. AMD will launch the Radeon RX 6600 XT on August 11, and will have GPUs in both desktops and laptops from leading OEMs—the laptops will use the previously announced RX 6600M. There's no reference design for the desktop card—the RX 6600 XT shown above is merely a 3D render for marketing purposes—but there will be compact single-fan solutions as well as the usual mix of dual- and triple-fan coolers from all the major graphics card partners. In a nutshell: the RTX 3060 offers similar rasterization performance, superior ray tracing, DLSS support, a bigger VRAM buffer, and a full PCIe 4.0 x16 connection, making it a better product – and if available at the same price, the obvious option. Moving on to Shadow of the Tomb Raider and we've got to say, these results look less favorable for the new mid-range Radeon GPU. Here at 1080p the 6600 XT was 19% slower than the 6700 XT and 17% slower than the RTX 3060 Ti, while it was just 2.5% faster than the 3060 and 4% faster than the old 5700 XT.
In fact, with the highest level of ray tracing enabled at 1080p, the 3060 Ti was good for 97 fps on average while the 6600 XT struggled with just 45 fps. Then with DLSS it was possible to boost performance up to 143 fps, so another ray tracing bloodbath here.
