Galax has accidentally leaked the yet-to-be-announced GeForce RTX 4090 Ti despite the 4090 having no competition whatsoever. The Radeon RX 7900 XTX manages to beat the RTX 4080 in rasterization but falls massively short in ray-traced games. (pinnaclemontessori.com) As the RTX 4080 is priced at $1,199 and the RTX 4090 at $1,599, the 4090 Ti should have an MSRP of $1,999, the same as the RTX 3090 Ti.
The GeForce RTX 4090 Ti is expected to be based on a better-binned, nearly fully enabled AD102 die with a 10-20% performance lead over the RTX 4090. According to AGF on Twitter, the fastest Ada Lovelace SKU 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.
We’re looking at a 10-20% improvement in gaming performance, with ray-traced titles 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.
