The first samples of the GeForce RTX 4090 Ti (or Titan?) are already out in the wild. The first shots of the GPU’s heatsink have surfaced on Twitter (via Zed_Wang), showing a massive 4-slot wide graphics card. Unlike the usual horizontal arrangement of the ports on the backside, we’re looking at a vertical layout consisting of three Display Ports and one HDMI.
You can compare top-end GPUs from three different generations below. The GeForce RTX 3080 Ti has a dual-slot design, the RTX 4080/4090 scale it up to triple-slot, and the now-leaked RTX 4090 Ti has four-slot wide.
Furthermore, similar to Moore’s Law is Dead, stated in a video earlier, the graphics card has a Golden-Black shroud, unlike the usual Silver/Grey scheme. There’s not much we can glean from these images except that board partners will be getting their first samples soon if they already haven’t.
The GeForce RTX 4090 Ti will 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 from 22.5Gbps to 24Gbps 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.
