AMD Radeon RX 7900 XT to get a hefty VRAM upgrade over the RX 6900 XT ↺
AMD recently confirmed the launch date and time for its Radeon RX 7000 graphics cards. However, the launch event, scheduled for November 3, will be host to only two high-end SKUs, namely the Radeon RX 7900 XT and Radeon RX 7800 XT. Both graphics cards are slated to use the multi-die Navi 31 GPU, but everything else is shrouded in mystery. Wccftech's sources have now let slip some important information about the RDNA 3 flagship.
The AMD Radeon RX 7900 XT will feature 20 GB of GDDR6 VRAM, 4 GB over the Radeon RX 6900 XT and RX 6950 XT. AMD initially planned to mimic Nvidia and launch it with 24 GB of VRAM. However, the idea was scrapped later because the Radeon RX 7900 XT isn't the king of the proverbial RDNA 3 hill. AMD has plans to launch an even more powerful graphics card later, the Radeon RX 7950 XT (tentative), likely with 24 GB of VRAM.
Performance estimates for RDNA 3 are all over the place. One report indicates that it will outperform RDNA 2 by over 100%, while another states that the Radeon RX 7900 XT might not be able to keep up with the GeForce RTX 4090. Raw performance notwithstanding, AMD could win the performance-per-dollar tag this time due to the graphics cards being remarkably cheaper to manufacture. It'll mirror AMD's CPU department, which lost out on the "bang for the buck" war with Intel's Raptor Lake processors due to a lack of DDR4 memory support and expensive motherboards.
