NVIDIA's GeForce RTX 4090 hasn't even hit retail yet and the rumor mill is already warming up the true flagship, the RTX 4090 Ti.
NVIDIA's GeForce RTX 4090 Ti Rumored To Offer Another 20% Performance Boost Over RTX 4090 With Up To 3 GHz Boost & 11% More Cores
The rumor regarding the NVIDIA GeForce RTX 4090 Ti comes from a Twitter leaker, @XpeaGPU, who claims that NVIDIA is saving up the best AD102 GPU dies for the RTX 4090 Ti. It shouldn't be much of a surprise as the same happened with the RTX 3090 Ti. The specs are insane though so let's start with what the rumor has to say.
Best dies are already saved for a 2.75Ghz boost (2.95 typ. gaming) 475W 18176 CUDA cores 96MB L2 cache 24Gb beast. Performance 10~20% above 4090 pic.twitter.com/z5XO8R9PyJ

The NVIDIA GeForce RTX 4090 Ti is said to be a partially cut-die with just 2 of the 144 SMs disabled for a total of 18176 CUDA cores. The GPU will come packed with 96 MB of L2 cache and a total of 224 ROPs which is simply insane. The card will retain the TSMC 4N process node and offer a nice boost to clock speeds with the card being rated at 2.75 GHz (Default) and hitting up to 2.95 or even 3 GHz boost clocks in typical gaming workloads. That's a +190 MHz increase in the default clocks.
As for memory specs, the GeForce RTX 4090 Ti is expected to rock 24 GB GDDR6X capacities that might come at faster 24 Gbps speeds across a 384-bit bus interface. This will provide up to 1.152 TB/s of bandwidth. Now all these boosted specifications will result in higher power draw too and the flagship is expected to operate at a TBP of around 600W. The card is said to feature a TGP of 475W which is a 25W increase over the RTX 4090 but custom variants may once again push this higher up in the 600W+ range.
We have seen that the NVIDIA GeForce RTX 4090 is an extremely efficient card and can be under-volted to 70% of its power budget and deliver the same performance. If it is true that the 4090 Ti uses binned dies, that might explain the lower wattage figure as NVIDIA could have optimized the voltages further. The graphics card is said to offer around 10-20% better performance than the RTX 4090 so that should definitely hit or even surpass the 2x performance figure over the RTX 3090 Ti which will be truly impressive. However, a card of this nature won't launch soon.
NVIDIA will most likely keep the beast under wraps until AMD has a formidable opponent in the RDNA 3 Radeon RX 7000 lineup so we may not get to see the RTX 4090 Ti in action for quite some time. NVIDIA also has to focus on more mainstream parts in the coming months.
