NVIDIA Readies GeForce RTX 4070 SUPER, RTX 4070 Ti SUPER, and RTX 4080 SUPER
NVIDIA is rumored to be working on a refresh of the higher end of its GeForce RTX 40-series "Ada" series, according to hongxing2020, a reliable source with NVIDIA leaks. The company could be bringing back the SUPER brand extension that it introduced with the RTX 20-series. As many as three SKUs are on the radar—GeForce RTX 4080 SUPER, GeForce RTX 4070 Ti SUPER, and the GeForce RTX 4070 SUPER.
There is no word on when the company plans to release these, or what their specifications are, but we can certainly speculate. The current RTX 4080, while based on the AD103 silicon, doesn't max it out—it uses 76 out of 80 SM (streaming multiprocessors) available on the silicon, but we doubt if those extra 4 SM could drive up enough performance to make a whole new SKU, especially given that the 256-bit memory bus of the AD103 is maxed out. We predict that the RTX 4080 SUPER could be based on the larger AD102 silicon that physically has 144 SM that the current RTX 4090 uses 128 out of. NVIDIA has the opportunity to pick an SM count such as, say, 96. AD102 also has a wider 384-bit memory bus, giving NVIDIA the option of either giving the RTX 4080 SUPER the same 24 GB memory configuration as the RTX 4090, or even 20 GB, across a 320-bit memory bus.As for the RTX 4070 Ti SUPER (an oddly named SKU that combines both the Ti and SUPER brand extensions), considering that the current RTX 4070 Ti maxes out the AD104 silicon (60 SM), it stands to reason that this new SKU could be based on AD103, with a lower SM count than the 76 of the RTX 4080. It remains to be seen if NVIDIA utilizes the full 256-bit memory bus. As for the RTX 4070 SUPER, there exists a rather wide gap between the current RTX 4070 Ti and the current RTX 4070. While the RTX 4070 Ti uses all 60 SM on the AD104, the RTX 4070 only uses 46. This gives NVIDIA the opportunity to get closer to the RTX 4070 Ti in SM counts, and bolster against AMD's Radeon RX 7800 XT.
