In terms of ray tracing, which has traditionally been one of AMD’s weak spots, the firm claims that the new cards contain a next-generation accelerator with 50% greater performance per computing unit. They will provide 1.5 times the number of rays in flight, new specialised instruction, and improved ray box sorting. That should imply closer ray tracing parity with NVIDIA’s GPUs. AMD’s new Radiance Display Engine, which supports 480Hz 4K gaming and 165Hz 8K performance, is also included in the Radeon 7000 GPUs. (And, sure, we think the latter is a stretch as well.)
So, how do these cards appear on paper? In addition to its enormous 24GB of GDDR6 RAM, the RX 7900 XTX has 96 compute units that operate at up to 2.3GHz and use 355 watts of electricity. Meanwhile, the 7900 XT has 84 CUs, a 2GHz clock speed, and a 300-watt power consumption, in addition to 20GB of GDDR6 memory. AMD has also collaborated with firms such as Samsung on a DisplayPort 2.1 display, which is expected to be available early next year. Surprisingly, Samsung revealed that its new Odyssey Neo G9 display would have an 8K ultrawide resolution. (The bigger issue is whether anybody should aspire for 8K gaming at all.)
