AMD Announces the Radeon RX 7600 XT 16GB Graphics Card

AMD announced the new Radeon RX 7600 XT graphics card, bolstering its mid-range of 1080p class GPUs. The RX 7600 XT is designed for maxed out AAA gaming at 1080p, although it is very much possibly to play many of the titles at 1440p with fairly high settings. You can also take advantage of technologies such as FSR 3 frame generation in games that support it, AMD Fluid Motion Frames on nearly all DirectX 12 and DirectX 11 games; as well as the new expanded AMD HyperRX performance enhancement that engages a host of AMD innovations such as Radeon Super Resolution, Anti-Lag, and Radeon Boost, to achieve a target frame rate.

The Radeon RX 7600 XT is based on the same 6 nm "Navi 33" silicon, and the latest RDNA 3 graphics architecture, as the Radeon RX 7600. If you recall, the RX 7600 had maxed out all 32 CU on the silicon. To design the RX 7600 XT, AMD retained the "Navi 33," but doubled the memory size to 16 GB, and increased the clock speeds. The 16 GB of memory is deployed across the same 128-bit wide memory bus as the 8 GB is on the RX 7600. The memory speed is unchanged, too, at 18 Gbps GDDR6-effective; as is the resulting memory bandwidth, of 288 GB/s. There are two key changes—the GPU clock speeds and power limits.
The Game Clock of the RX 7600 XT is set at 2.47 GHz, compared to 2.25 GHz on the RX 7600; and the maximum Boost Clock is set at 2.76 GHz, compared to 2.66 GHz on the RX 7600. To support these, and improve boost clock residency, AMD increased the total board power (TBP) to 190 W, up from 165 W on the RX 7600. As a result, the RX 7600 XT custom-design graphics cards will feature two 8-pin PCIe power connectors, or at least a combination of 6-pin and 8-pin; while the RX 7600 made to with just one 8-pin.

Another small change with the RX 7600 XT is that board partners will be mandated to wire out DisplayPort 2.1 on their custom boards (to use the required clock drivers and other ancillaries); they cannot opt to have DisplayPort 1.4 to save costs.

The 6 nm "Navi 33" silicon physically features 32 RDNA 3 compute units (CU), adding up to 2,048 stream processors, 64 AI accelerators, 32 Ray accelerators, 128 TMUs, and 64 ROPs. A 32 MB Infinity Cache memory cushions the 128-bit GDDR6 memory interface, which on the RX 7600 XT drives 16 GB, running at 18 Gbps.
Thanks to the increase engine clocks, the RX 7600 XT is shown posting a proportionate increase in performance across popular titles at 1080p with maxed out settings, including ray tracing. The RX 7600 XT is shown posing a near doubling in performance over the GeForce RTX 2060 6 GB. The RX 7600 XT is also shown offering playable frame rates at 1440p with max settings (albeit without ray tracing). AMD is making the case for 16 GB with creator and generative AI applications, where the large video memory should come very handy.

AMD Radeon RX 7600 XT will be available on January 24, 2024. It is exclusively a partner-driven launch, there will be no reference design in the retail market. AMD set $329 as the baseline price for the RX 7600 XT, a $60 premium over the RX 7600.

btk2k2This is pure truth. If someone wants to build a more budget friendly PC that can keep up with the consoles for the rest of the generation they now have some options. Before the 6700XT got as cheap as it is or the 7600XT launch you had to pay quite a lot more for a GPU that had that balance and it was not worth it over just buying a console unless there were specific PC only games you wanted.

Sure you will need to make compromises but you should be able to maintain console like IQ and have more FPS or have the same FPS and higher IQ, sometimes you will be able to turn on RT if the game has a console like RT setting available (how worthwhile it is to turn on is upto the user).

Neither of these parts will hit VRAM walls at certain settings combinations like the 3070/3070Ti and other more power 8GB cards do. Just look at the Ratchet and Clank example at 1080p. The 6700 XT is 2x faster than the 7600 and the 6700XT is no where near 2x the compute performance. I fully expect the 7600XT hit more than 60 fps in that game at that setting, maybe even more like 70+ depending on how VRAM vs compute vs bandwidth limited the bottlenecks are.
1080p is the area where any upscaling performs poorly. Hitting 60 FPS with 6700 XT, let alone 7600 XT, will require from the user to go below Ultra settings in many upcoming titles. Hardware ray tracing on these GPUs is obsolete already; software ray tracing is gonna survive but it doesn't contribute much to both IQ and VRAM consumption. Of course you can live with that and both GPUs technically will do just fine if you're content with minimum settings/30 FPS. VRAM staying at 8 GB is only an issue in two or maybe three games that aren't absolute rubbish.

1440p is the area where DLSS starts making sense whereas FSR is still bad. GPUs such as RTX 4060 non-Ti are doing just fine with DLSS Balanced turned on and they will do just fine for extended amount of time, even longer than in "pure" 1080p. Either of these three GPUs will hit their calculating power ceiling long before hitting 8+ GB being an absolute necessity.

4K? These GPUs ain't about that. If you can play games at 4K with such GPUs it's cool but that's not intended. And this is the only resolution you can realistically hit 8+ GB requirement on a somewhat regular basis next three or four years.

It's not nonsensical to assume that the 16 GB version of 7600 will get more longevity than the 8 GB variant. Yet, it's still losing to:

• 6700 XT in basically everything that's not power efficiency. 16 GB over 8 GB can make a difference but 16 GB over 12? No way, both GPUs will run outta steam long before hitting 11+ GB VRAM usage.
• 4060 in everything that's not VRAM capacity. 4060 will provide better experience in 99% titles next couple years and by 2027, GPUs of such calibre are essentially $50 worth e-junk.
• 3060 Ti, or 3070. Same story as with 4060 but these GPUs have more horsepower and will provide more value at higher resolutions due to actually existent VRAM bandwidth.
• Intel Arc A770 16 GB. Essentially cheaper and much more powerful as you increase the resolution and/or RT load. Of course Arc GPUs are still in their beta stage but don't forget about XeSS: it's superior to FSR.
• Its own 8 GB variant just because it's so much more expensive.
• Second hand 6800 non-XT. Nuff said.

It doesn't achieve anything. Would've been somewhat good as a replacement at the same MSRP of ~260 USD but AMD are willing you to sacrifice almost 30% more than that. It's horrendously slow for its money considering available options. Its 16 GB VRAM buffer only pays off in a couple certain games and gambling about VRAM hogging becoming a trend rather than an incident-based happening, this makes minimum sense. Spend 70 bucks more = get a new RX 6800 with 60+ % performance advantage. Spend about 40 dollars less = get an RTX 3060 12 GB which has essentially the same longevity. Or an RTX 4060 that's even more superior if we account it being 80 Watts easier on the PSU.
