VideoCardz has revealed an architectural design for AMD's RDNA3 GPU, and it looks like there is a lot of potential in the RX 7000 series.

From the picture, the whole RX 7900 system adopts the new flagship GPU Navi 31 of AMD, but the RX 7900 XTX enables the full GCD and 6 MCDS of Navi 31, while the RX 7900 XT only enables 84 out of 96 computing units and 5 MCDS.

And most importantly,Architecture design drawings show that the RNDA3 GPU frequency can exceed 3GHz, the first in the industry. The RX 7900 XTX public version of the Boost frequency is only 2.5GHz, so you can still improve performance, so the RTX 4090...

Why would you do that? It is said that AMD in the public version of the graphics card with dual 8pin power supply, limited the graphics card power to power consumption performance balance, so the non-public version of the model will use better heat dissipation and power supply, to achieve 3GHz frequency, unlock more performance.

In this way, 7999 yuan RX 7900 XTX and 7399 yuan RX 7900 XT are more cost-effective.
