NVIDIA is currently working on two new mobile GPUs for laptops, one being the recently rumored GeForce RTX 3080 Ti, and it now appears that a new GA104 silicon has recently been uncovered on the PCI Device ID database.
NVIDIA Readies GeForce RTX 3070 Ti & RTX 3080 Ti Laptop GPUs To Tackle Intel ARC Alchemist Lineup
Website VideoCardz unearthed a comment from the user Faintsnow on the PCI Device ID database site about a specific ID that appeared, ID 24A0, that is referring to a NVIDIA mobile GPU, the NVIDIA GN20-E6. It is believed that the GN20-E6 is the moniker given to the NVIDIA GeForce RTX 3070 Ti Laptop GPU. The NVIDIA Laptop GPU is not currently listed with the remainder of the NVIDIA Ampere family.
If this information is true, then NVIDIA is beginning to start looking at manufacturing RTX 3080 Ti and RTX 3070 Ti GPUs for mobile devices, such as laptops and notebooks, which will offer more core counts than the non-Ti models.
The RTX 3080 Ti is speculated to use a newer graphics processor, the GA103, which has been showcased to have as high as 7680 CUDA cores. The mobile version of this particular graphics processor would more than likely produce less CUDA cores than the desktop versions. The NVIDIA RTX 3070 Ti, however, would possibly be higher than the non-Ti models, which have as high as 5120 CUDA cores due to the current leading NVIDIA SKU offering 6144 CUDA cores.
This new information conveniently appears after the release of the launch timeframe for the next-gen Intel Arc Alchemist graphics processors, which are to appear as early as the first quarter of next year.
The Alchemist 512 EU chip is expected to measure at around 396mm2 which makes it bigger than the AMD RDNA 2 and NVIDIA Ampere offerings. The Alchemist -512 GPU will come in the BGA-2660 package which measures 37.5mm x 43mm. NVIDIA's Ampere GA104 measures 392mm2 which means that the flagship Alchemist chip is comparable in size while the Navi 22 GPU measures 336mm2 or around 60mm2 less.
With speculations of Intel's newest discreet DG2-512EU-based GPUs giving stiff competition with GA104 models, NVIDIA might be looking to level the playing field with these new PCI Device IDs.
