AMD's Radeon RX 7900 XTX could be crazy powerful
Yesterday, we discussed AMD's rumoured Radeon RX 7900 XT, a graphics card that is rumoured to be an RTX 4090 competitor with 20GB of VRAM that uses cut-down Navi 31 silicon. We also discussed AMD's RDNA 3 flagship, a higher-end graphics card that features higher-end specifications that supposedly surpass Nvidia's RTX 4090.
According to a new report from benchlife.info, AMD's RDNA 3 flagship will be the Radeon RX 7900 XTX, a 24GB graphics card that will feature more stream processors and more memory bandwidth.
Why would AMD call their next-generation flagship the RX 7900 XTX and not the RX 7950 XT? In our eyes, it looks like AMD wants to reserve the RX 7950 XT name for a future RDNA 3 refresh. Beyond that, XTX does sound like a higher-end brand than RTX, so it is equally possible that AMD is simply trying to steal some of Nvidia's thunder. Then again, the XTX brand has been part of Radeon since back in the ATI era, before AMD acquired the company. Remember the Radeon X1900 XTX?
Assuming that the RX 7900 XT and RX 7900 XTX use the same type of GDDR6 memory, AMD's RX 7900 XTX will offer gamers 20% more memory bandwidth thanks to its use of a wider memory bus (384-bit vs 320-bit). When compared to AMD's Radeon RX 6900 XT, the Radeon RX 7900 XTX will offer users a 50% memory bandwidth upgrade thanks to the GPU's wider memory bus. This memory bandwidth upgrade will be even larger if AMD decides to use faster GDDR6 memory modules.
If recent reports from Videocardz are correct, AMD's RX 7900 XT will feature 10752 stream processors and AMD's RX 7900 XTX will feature 12288 stream processors. Both of these GPUs offer users more than two times as many stream processors as AMD's Radeon RX 6900 XT (which has 5120 stream processors). If this is accurate, AMD has the potential to deliver a greater than 2x increase in computational performance with their top RDNA 3 graphics cards. Beyond that, AMD has promised "re-architected compute units" with their RDNA 3 graphics cards, an upgrade that is sure to increase AMD's GPU IPC (Instructions Per Clock/Cycle) and ray tracing performance.
AMD's first RDNA 3 based graphics cards will be revealed on November 3rd, and if today's rumours are anything to go by, these graphics cards will be very impressive. That said, it remains to be see how these new GPUs will perform in games, and how they will compare with Nvidia's RTX 40 series.
