NVIDIA GeForce RTX 3080 and RTX 3070, unveiled the alleged technical specifications

Although not definitively confirmed, GeForce RTX 3080 is GeForce RTX 3070 should represent the new NVIDIA high-end proposals for the consumer graphics card segment, the first based on the new architecture Ampere at 7nm, apparently capable of offering a 50% increase in performance compared to current solutions with GPU Turing.

NVIDIA has so far not been unbalanced in giving details on the next generation of Ampere GPUs, however in the last few hours there have been several rumors about what will be the technical specifications of these chips. The information, we emphasize still unofficial, comes from mydrivers.com and coincide with those that appeared just a couple of days ago on the twitter profile KittiCorgi complete with GPU block diagram (link in the STREET).

According to what reported, at the base of GeForce RTX 3080 and GeForce RTX 3070 there will be respectively the Ampere GA103 and GA104 GPUs: the first equipped with 60 SM (Streaming MultiProcessors) e 3840 Cuda Core, the second with 48 SM e 3072 Cuda Core. Analyzing the data well, it is a relationship similar to that existing between GeForce RTX 2080 and RTX 2070 (48 vs 36 SM) but with a clear (and obvious) increase in processing units.

As for memory, the Ampere GA103 GPU (i.e.GeForce RTX 3080) will support 10 / 20GB of GDDR6 memory on 320-bit bus, the younger sister GA104 instead stops at 8 / 16GB GDDR6 on 256-bit bus. For the moment NVIDIA has not commented on the news, further details may emerge however at the GDC in March where we will also have the first technical details on the Intel Xe GPUs.
