AMD Announces RX 7900 XT and 7900 XTX Graphics Cards Using Its New RDNA3 Architecture PaulSakuma.com photo However, instead of going head-to-head with Nvidia’s RTX 4090, AMD said it was targeting the $1,000 price point, suggesting it only plans to compete with the RTX 4080 and below for now. Another interesting announcement was that the new 7900 series cards will not use a PCIe 5.0 interface – they will stick with PCIe 4.0 as Nvidia has already done with the RTX 40 series. AMD’s main goal was to increase performance per watt, and it did so in part by using the first GPU-based chiplet architecture. This includes a 5nm Graphics Compute Die with 18 percent higher frequency and 54 percent higher performance per watt than the previous generation. The result is a board power of 355 W for the RX 7900 XTX and 300 W for the RX 7900 XT. AMD was keen to point out that the cards won’t require special power connectors.

Radeon RX 7900 XTX from AMD AMD The new GPUs have 165 percent more transistors per square millimeter and offer up to 61 Tflops of computing power compared to 23 Tflops for RDNA2 – a 2.7x increase. In raw performance terms, this, AMD claims, will deliver an average 1.7x increase in 4K gaming performance compared to the RX 6000 series. Radeon RX 7900 XT from AMD AMD The RX 7900 XTX will have 24GB of GDDR6 memory, while the RX 7900 XT will make do with 20GB. Both will feature a new DisplayPort 2.1 interface that will bring increased bandwidth and higher refresh rates to 4K (480) and 8K (165) AMD also announced an upcoming update to its FidelityFX Super Resolution frame rate boost feature – FSR 3 with fluid motion – which will deliver up to twice the frame rate improvements of FSR2 and will be released on PC in 2023.
