The GeForce RTX 4090 just hit the retail market, and we’ve already started hearing rumors about its buffed-up sibling, the 4090 Ti. According to AGF on Twitter, the Ada Lovelace top chip will utilize the (near) fully enabled AD102 die featuring 18,176 FP32 cores across 142 SMs. For reference, the AD102 core comes with 144 SMs or 18,432 shaders. These dies will be cherry-picked bins, boosting up to 3GHz, a 200-300MHz bump over the RTX 4090.
The L2 cache on the Ti will also be a significant upgrade over the RTX 4090. While a 72MB LLC buffer complemented the latter, the 4090 Ti will utilize the 96MB available on the AD102. The memory will likely be pushed to 24Gbps, from 22.5Gbps on the current flagship. All these changes will result in the GPU yearning for more juice. The RTX 4090 Ti is expected to have a TGP of 475W, a 25W bump over the 4090.
In terms of gaming performance, we’re looking at a 10-20% improvement with ray-traced titles, maybe even extending the lead to 25-30%. There’s no word on the launch timing of the 4090 Ti, but if I had to hazard a guess, I’d place it around mid to late 2023. The budget and entry-level Lovelace parts ought to arrive first.
