| numberwang said: Samsung 8nm node confirmed by pro leaker Kopite7? https://www.youtube.com/watch?v=qSUYzzEfTm4 That would be less than ideal as Samsung 8nm is a power hungry node (used in the Nvidia 3000 GPUs). We would be looking at less than 400MHz GPU clock in mobile mode and maybe 1 Tflop performance. For comparison: Steam Deck has ca. 1.6 TFlops and is produced with the better TSMC 7nm node. One comment explains the main issue: Hey Doc, it's almost certainly not going to be 8nm, simply because 1536 cuda cores at 422mhz already draws 6watts for just the GPU via Nvidia's own numbers and delivers only 1.29TFLOPs, pushing 8 A78C cores even at 1.5w would use 2w, that means for the SoC alone, it would draw 8w, the screen, ram, other components would all draw 3 or 4 watts minimum, but the issue with 8nm is deeper than this, it's the configuration of the chip itself, see a GPU with only 1024 cuda cores at 600MHz would do 1.23TFLOPs, draw about the same amount of power, while also costing much much less. The reality is that Drake is too big of a configuration for these low clocks to make sense economically. It's also worth noting that Kopite7 has specifically gotten nodes wrong, and T239 info wrong, even in your video he had the wrong code name, and thought both Orin and Drake were Ada Lovelace and not Ampere. They are GA10B and GA10F, GA standing for Geforce Ampere, Ada Lovelace is specifically AD10X chips. |
He did definitely get Tegra T239 correct, but then seems to have gotten some of the finer details incorrect. Said the codename was "Dane Whitman", when it has "Tim Drake", initially said 2048 CUDA cores I think, and said it was Lovelace. It could be 8N sure, but at 8N even at what they're describing, the chip would be a lot bigger than a Tegra X1, so is Nintendo looking to make something significantly larger this time? Did they look at the Steam Deck and get jealous? lol. What he's describing is a very large device.
I think the direct leaks from Nvidia are more correct because they are (well) direct actual data leaks from Nvidia themselves that was not supposed to be shared with the public. In those hacks we do see a Tegra T239 but it's listed at 1536 CUDA cores, 12SM configuration, Ampere. At 8nm that chip would be massive, like I believe larger than the chip in the Legion GO (huge ass handheld).
My guess would be he got some info mixed up as he's made a few mistakes there, or maybe since his leak is very old (March 2021) as well. Who knows maybe Nintendo was planning to launch earlier initially (March 2023?) and moved back to fall 2024 opening the door to a better node process being available. The other thing is in one of his tweets they write "SEC8N ?", the question mark implying they're not sure of that info.
