Greymon55 claims to have obtained images of NVIDIA’s GeForce RTX 4090 Ti graphics card with the full-fat AD102 GPU. According to reports, the card shown is equipped with NVIDIA’s full-fat AD102 GPU, which is based on the Ada Lovelace chip design. The full-fat chip will probably have a TBP of 600W (+), therefore it will need some powerful cooling methods.
According to the leaker, this appears to be an early engineering sample meant to test the maximum performance of the enormous AD102 GPU, which will be available to consumers in a few months. This seems to suggest that the AD102 will be a difficult chip for AIBs to cool down, even if the final model for the Founders Edition design is anticipated to employ a significantly different cooler.
This is not the first time that a triple-fan cooler for the standard AD102 board has been mentioned. This leak appears to be validation of Kopite7kimi’s earlier observation that a triple-fan and a three-slot cooler were specifically designed for AD102 GPUs.
In terms of sheer size and width, the card itself appears to be fairly thick. The triple-fan system has an axial-blade design, and the shroud conceals a sizable heatsink. The shroud is fairly plain and has a matte black appearance. It appears that the card has a 3-slot form factor. If this is actually a 600W model, then a single Gen5 connector should be sufficient to start it up unless the ES design includes two of those connectors as NVIDIA has been using a 16-pin connector.
The full-fat version of the NVIDIA GeForce RTX 4090 Ti will have all 144 SMs enabled, giving it a total of 18432 CUDA cores.
The GPU will have 384 ROPs in total and 96 MB of L2 cache, which is just ridiculous. Although the clock rates have not yet been confirmed, given that the TSMC 4N process is being used, we anticipate clocking in the 2.0-3.0 GHz region.
The GeForce RTX 4090 Ti is anticipated to feature 24 GB of GDDR6X memory, possibly operating at faster 24 Gbps rates over a 384-bit bus interface. A bandwidth of up to 1.152 TB/s will be made available. Now that the specifications have been improved, there will also be an increase in power consumption, and the flagship is anticipated to run at a TBP of about 600W.
A single 16-pin Gen 5 connector should be adequate for 600W, but most custom variants will undoubtedly use dual Gen 5 connectors because AIBs don’t always operate within specification and even the smallest factory overclocks will cause the TBP to exceed the 600W limit of a single Gen 5 power connector.
