Earlier it was reported that a GPU called the Ampere GA102-250 GPU SKU exists In Nvidia’s sectors. Now a user on Hardwareluxx Forums has confirmed that the GPU which was previously expected to be featured on the GeForce RTX 3080 Ti graphics card exists.
According to sources, the GPU was spotted when the forum member took apart his GeForce RTX 3090, and the GPU was initially labeled as the GA102-250 SKU instead of the GA102-300 which is supposed to be the official SKU used on the RTX 3090.
Until now, the NVIDIA GA102-250-KD-A1 GPU only existed in rumors, but now it is confirmed to be a real chip. The GPU was initially planned for the GeForce RTX 3080 Ti graphics card, but it seems that the green team decided to utilize it for the GeForce RTX 3090 graphics card.
The image posted by the user, clearly shows that the GA102-250-KD-A1 GPU label has been cut-off, and instead, it’s been repurposed as the GA102-300-A1 SKU. According to previous reports, we had heard that the GA102-250-KD-A1 was expected to feature 78 SM units enabled for a total of 9984 CUDA cores whereas the RTX 3090 with its GA102-300-A1 GPU packs 82 SMs or 10496 cores.
It is also being speculated that NVIDIA decided to repurpose the GA102-250 SKU into GA102-300 due to the shortages of its high-end graphics cards. The NVIDIA GeForce RTX 3080 Ti has seen a spec-change and will now be using the Ampere GA102-225-A1 GPU SKU. Following are the expected specifications of the upcoming RTX 30 series flagship.
