AMD officially releases Radeon RX 7900 GPUs
Today is the day you can buy the new Radeon GPUs based on the RDNA3 architecture.
AMD is kicking off its new series with the high-end models first, and the company announced the RX 7900 XTX and RX 7900 XT a few weeks ago, but today is the day these cards finally go on sale.
The AMD Radeon RX 7900 XTX features a full Navi 31 GPU with 6144 Stream coprocessors. This GPU has a clock boost of up to 2.5GHz, however Show reviewers That this frequency can go up a lot – it all depends on the workload. Maximum computing performance is measured at 61 TFLOPs.
The XTX variant features 24GB of GDDR6 memory and has a TDP of 355W. This is the flagship model that requires an 800-watt power supply and two standard 8-pin power connectors. However, the vast majority of custom cards will require three.
The AMD RX 7900 XT features a Navi 31 detuned GPU with 5376 cores. The memory size is reduced to 20 GB which also means that the memory bus is 320 bits narrower. With a clock speed of up to 2.4GHz, AMD estimates computing performance at up to 52 TFLOPs. The company made a last-minute change to the specs by adding 15 watts to the board’s total power. It’s now at 315 watts, so it’s only 40 watts less than the XTX GPU.
Some custom cards are already available through Amazon US (affiliate links):
Board Partners is expected to fully reveal all remaining custom designs soon. There is also a ban on reviewing custom templates, but we have already collected some of them in this post.
