Graphics card buyers seem to have a lot of anxiety about buying a GPU with enough memory installed, even in midrange graphics cards that aren't otherwise equipped to play games at super-high resolutions. And while this anxiety tends to be a bit overblown—lots of first- and third-party testing of cards like the GeForce 4060 Ti shows that just a handful of games benefit when all you do is boost GPU memory from 8 to 16GB—there's still a market for less-expensive GPUs with big pools of memory.
That's the apparent impetus behind AMD's sole GPU announcement from its slate of CES news today: the $329 Radeon RX 7600 XT, a version of last year's $269 RX 7600 with twice as much memory, slightly higher clock speeds, and higher power use to go with it.
| RX 7700 XT | RX 7600 | RX 7600 XT | RX 6600 | RX 6600 XT | RX 6650 XT | RX 6750 XT | |
|---|---|---|---|---|---|---|---|
| Compute units (Stream processors) | 54 (3,456) | 32 (2,048) | 32 (2,048) | 28 (1,792) | 32 (2,048) | 32 (2,048) | 40 (2,560) |
| Boost Clock | 2,544 MHz | 2,600 MHz | 2,760 MHz | 2,490 MHz | 2,589 MHz | 2,635 MHz | 2,600 MHz |
| Memory Bus Width | 192-bit | 128-bit | 128-bit | 128-bit | 128-bit | 128-bit | 192-bit |
| Memory Clock | 2,250 MHz | 2,250 MHz | 2,250 MHz | 1,750 MHz | 2,000 MHz | 2,190 MHz | 2,250 MHz |
| Memory size | 12GB GDDR6 | 8GB GDDR6 | 16GB GDDR6 | 8GB GDDR6 | 8GB GDDR6 | 8GB GDDR6 | 12GB GDDR6 |
| Total board power (TBP) | 245 W | 165 W | 190 W | 132 W | 160 W | 180 W | 250 W |
The core specifications of the 7600 XT remain the same as the regular 7600: 32 of AMD's compute units (CUs) based on the RDNA3 GPU architecture, and the same memory clock speed attached to the same 128-bit memory bus. But RAM has been boosted from 8GB to 16GB, and the GPU's clock speeds have been boosted a little, ensuring that the card runs games a little faster than the regular 7600, even in games that don't care about the extra memory.
