NVIDIA GeForce RTX 3080 Ti GPU rumors, the Ampere GA102-250, located on a GeForce RTX 3090 graphics card

A user on the Hardwareluxx Forums confirmed the existence of the NVIDIA SKU Ampere GA102-250 GPU, which was previously expected to be featured on the GeForce RTX 3080 Ti video card. It was detected when the forum member disassembled his GeForce RTX 3090, just to reveal that the GPU had initially been labeled as GA102-250 SKU instead of GA102-300, which is the official SKU used in the RTX 3090.

The NVIDIA GA102-250-KD-A1 GPU existed only in the rumor, but now we can confirm that this is really a real chip. Initially planned for the GeForce RTX 3080 Ti video card, it looks like NVIDIA decided it could use an additional cut-off SKU to power the next flagship, while this SKU can be used for the GeForce RTX 3090 video card. You can see clearly that the GA102-250-KD-A1 GPU label has been cut and has instead been reused as SKU GA102-300-A1. What is interesting is that the GA102-250-KD-A1 was expected to feature 78 SM units enabled for a total of 9984 CUDA cores, while the RTX 3090 with its GA102-300-A1 GPU packs 82 SMs or 10496 cores.

It is possible that NVIDIA has decided to redirect SKU GA102-250 to GA102-300 due to the scarcity of its cutting-edge graphics cards. We cannot say with certainty whether the 250 variant offers the same performance / power limits as the 300 variant, but given that it has a lower naming scheme, it can be expected to be a lower compartment than the standard GA102-300 SKU . The GPU was also made during the 49th week of 2020, which runs from late November to early December. Again, we don’t know how far NVIDIA is redirecting its GA102-250 chips to GA102-300, but as they exist and that is out now, we can expect more users to find out for themselves.

The NVIDIA GeForce RTX 3080 Ti, on the other hand, has undergone a change in specifications and will now use the Ampere GPU SKU GA102-225-A1. The following are the specifications expected from the next flagship of the RTX 30 series.

The NVIDIA GeForce RTX 3080 Ti 12 GB FE (Founders Edition) graphics card must feature the PG132-SKU18 PCB design and the GA102-225-KD-A1 graphics core. The GA102-225 GPU has also changed since the last time we saw them and will now feature 10240 CUDA cores in a total of 80 SM units. Since the main core configuration is completely new, leaked clocks and TMU / ROP counts must previously be discarded.

As for memory, the card will have 12 GB of GDDR6X memory. Unlike the RTX 3090’s 19.5 Gbps speeds, the GeForce RTX 3080 Ti retains the same memory speeds as the RTX 3080 at 19 Gbps. As we are getting 12 GB of memory, the NVIDIA GeForce RTX 3080 Ti will use a 384-bit bus interface, which equates to a total bandwidth of 912 GB / s. Therefore, although we see a reduction of 8 GB VRAM compared to the previous specification, the larger bus interface should generate a larger memory bandwidth.

The TGP for the board is set to be the same as the RTX 3080 at 320 Watts. This is definitely necessary to power the extra cores, so NVIDIA may have to optimize the clocks here a bit. The NVIDIA GeForce RTX 3080 Ti is expected to launch in mid-April for a suggested price of around $ 999. It is rumored that the card will be launched in May.
