Leaker claims Nvidia's Hopper compute GPUs are taping out soon, might launch in mid-2022
Those rumors that were suggesting Nvidia could launch the Ampere successor this year will most likely prove false, since we already know Team Green is aiming to launch the Ampere Super first and this will not happen until 1H 2022, which makes sense given the chip shortages and crypto mayhem. Nvidia usually launches the compute-oriented GPUs first, followed by the gaming versions after some months, so maybe we can at least see new HPC GPUs in late 2022? The probability is quite high, as implied by a tweet from Greymon55, a leaker that is most known for AMD-related rumors. Unfortunately, the cryptic tweet was deleted, but 3DCenter screenshot everything so now we know that it was stating “Nvidia Hopper will tape out soon.”
Hopper is expected to be Nvidia’s first multi-chip-module GPU designed to compete with Intel’s Xe-HPC and AMD’s CDNA2. While it will not be used in the upcoming gaming GPUs, it will most likely serve as base, just like all the current GA1xx chips are derived from the A100. Following the established codename scheme, this generation will get the H100 moniker, and is expected to integrate 5 nm transistors from TSMC. Leaker kopite7kimi believes that Hopper will feature two interconnected dies with a total of 288 streaming multiprocessors, which should provide three times the performance of the A100. The H100 taping out soon probably refers to a fall 2021 tape out and launch may be scheduled for mid-2022 at the soonest.
Nvidia is also supposed to be working on the Ada Lovelace architecture that would power the 2023 generation of gaming GPUs. However, this architecture does not seem to be derived from Hopper, so it might not feature a multi-chip approach, but should still be produced on TSMC’s 5 nm nodes, with an expected performance uplift of around 2x over GA100.
