Rumour has it that NVIDIA will unveil Ampere GPUs, the RTX 3000 series, next month at GTC 2020. While we already know that the architecture will be manufactured on a 7 nm process, new leaks claim that the RTX 3000 series will sport up to 826 mm² dies, 20 GB of VRAM and support for PCIe 4.0. All this and other improvements will combine to allow Ampere GPUs to deliver up to double the performance that the existing RTX 20 series does.
Alex Alderson,

AMD may have "big Navi", but NVIDIA has Ampere. While the latter's upcoming 7 nm architecture has mentioned a lot of late, little in the way of specifics have been offered. Now, someone has posted a slew of information on Twitter, which claims to explain multiple elements of the upcoming RTX 3000 series.

Before we get into the information, we should point out that all this remains unverified for the time being. Hence, it could all be speculative, fake or without merit. Alternatively, it could all be bang on, although that seems unlikely.

Tweeting as @CorgiKitty, the unnamed leaker has tweeted about the GA100, GA103 and GA104, which are all supposedly Ampere and RTX 3000 series GPUs. Apparently, the GA100 is the flagship of the three and will feature an 826 mm² die. @CorgiKitty has detailed how NVIDIA will arrange the die, too. The account claims the following, too:

  • INT32 Unit remains unchanged.
  • Double the FP32 Unit for shader proportion.
  • The performance of the new Tensor Core is doubled.
  • Enhanced L1 Data Cache for more comprehensive functions.
  • True architecture for RTX GAMING with all-new design RT CORE ADVANCED.

Apparently, the GA103 will feature 60 SMs. This may yield 3,840 or 7,680 CUDA cores depending on the ratio of cores per SM. Wccftech also notes that the GeForce RTX 2080 Ti has 64 cores per SM, meaning 4,608 CUDA cores spread across 72 SMs. @CorgiKitty claims that the GA103 will have 10 GB or 20 GB of VRAM too, which would be huge by today's standards.

Finally, the GA104 will supposedly have 48 SMs. As per the information about the GA103, the GA104 will have 3,072 or 6,144 CUDA cores. Moreover, the GPU will 8 GB or 16 GB of VRAM that will operate on a 256-bit bus.

Overall, the above should deliver up to twice the performance that the current RTX 20 series offers. @CorgiKitty mentions that a GA102 is in development, too. However, they offer no details on this GPU apart from that NVIDIA is evaluating the performance of Navi 21 before making adjustments to GA102.

Again, the above could come to nothing. Would any of the above tempt you into purchasing an RTX 3000 series GPU, though?
