NVIDIA GeForce RTX 3070 Ti and RTX 3080 Ti Alleged Memory Specs and ASIC Codes Surface
An add-in card partner source shared with VideoCardz some juicy details about a pair of upcoming high-end GeForce RTX 30-series "Ampere" graphics cards. Called the GeForce RTX 3070 Ti and GeForce RTX 3080 Ti, the two are aimed to restore NVIDIA's competitiveness against the likes of AMD's recent Radeon RX 6000 series GPUs. It looks like NVIDIA doesn't want to play the memory size game just yet, despite giving the RTX 3060 12 GB of it.
The GeForce RTX 3070 Ti appears to be maxing out the GA104 silicon and carries the ASIC code "GA104-400-A#." The current RTX 3070 enables all but one of the TPCs on the GA104, working out to 5,888 CUDA cores. The new RTX 3070 Ti probably maxes out the GA104 to its CUDA core count of 6,144. The more substantial upgrade, however, is memory. The card ditches 14 Gbps GDDR6 for fast GDDR6X memory of an unknown speed—probably higher than 16 Gbps. The memory size remains 8 GB, across 256-bit.The GeForce RTX 3080 Ti is a different beast. The card is based on the same GA102 silicon as the RTX 3080, but carries the ASIC code "GA102-225-A#." compared to the "GA102-200-" of the RTX 3080. This to us hints at the likelihood of the RTX 3080 Ti featuring only slightly more TPCs than the RTX 3080; with much of its design effort focused on memory. The card gets 12 GB of GDDR6X memory, maxing out the 384-bit memory interface of the GA102.
The source expects a mid-April launch for the RTX 3080 Ti, as the RX 6800 series and RX 6900 XT irk NVIDIA more. The RTX 3070 Ti, on the other hand, could see a late-May launch.
