On November 3, AMD introduced the new generation Radeon RX 7900 graphics cards based on the RDNA 3 architecture. Two models are announced – Radeon RX 7900 XTX and Radeon RX 7900 XT. The first is equipped with a full-fledged Navi 31 GPU with 12288 streaming cores, and the second is based on a chip with 10752 cores.
It is the first chiplet-based graphics computing architecture. The chip consists of a 5 nm computing chip and six memory chips (6 nm). Recall that NVIDIA Ada Lovelace processors are manufactured using 4 nm technology.
The Navi 31 GPU is comprised of 58 billion transistors and delivers up to 61 TFLOP single precision performance. The connection inside the chiplet runs at 5.3 TB/s. Navi 31 GPU has 165% higher transistor density compared to Navi 2X.
AMD confirms that its new RX 7900 XTX will be 1.7 times faster than the RX 6950XT at 4K resolution. The company shared performance results in some popular games:
The Radeon 7900 XTX is the first graphics card to support the DisplayPort 2.1 display interface, providing output at resolutions up to 8K/165Hz or 4K/480Hz. The VideoCardz website has summarized the parameters of new products and their already sold competitors in a table:
The recommended prices for the new graphics cards have been announced: the Radeon RX 7900 XTX will cost $999, and the RX 7900XT will cost $899. The price makes the cards interesting in comparison to the NVIDIA RTX 4090 and 4080, but we should wait for independent gaming tests.
The nominal power consumption of the cards is 355 W and 300 W. To connect them, you will need two ordinary 8-pin connectors – you will not need a new power supply, adapters, or any other PC upgrade. The new items will go on sale on December 13. The full video of AMD’s broadcast is available below.
