You'd say with this performance it should be no problem running GRUB @1080p. I guess not...

mdedetrich Not saying there's no objective way to measure, I'm just saying those fabrication processes are nowhere near what they claim. But I agree with you about TSMC.

Long story short = there's a lot of space for imporvement actually for years to come, and their numbers are sort of "pulled out of their sittng places" (in a way at least).
In any case, right now TSMC has the best silicon you can get and Samsungs 8nm is no way close to TSMC's 7nmLast edited by mdedetrich; 07 October 2020, 07:16 PM.

Much more likely is that NVidia was trying to get TSMC to manufacture the 7nm die for their 3000 series GPU's but because they were so bullish/aggressive they didn't get any capacity from TSMC (also to note that NVidia doesn't have the best history with TSMC, they used them in the past and didn't get the best results). So instead they had to settle with inferior 8nm node from Samsung (which tbh is probably closer to a 10nm node).
So the only way that NVidia could get such performance in their cards was by feeding them more power, its the same reason the cards are so hard to overclock. NVidia is basically doing the same thing as Intel, only difference is that NVidia unlike Intel doesn't have their own fab.

Unfortunately Linux was kind of collateral damage here.
If that's the case, they really extinguished the fire with gasoline, because Nvidia videocards have now a limited lifespan depending on Nvidia... or stay on very basic 2D/3D rendering by nouveau (even slower than Intel Graphics)

This of course backfired greatly since TSMC already has plenty of other customers happy to pay higher for their premium die, so TSMC just said f'off to NVidia. Its true that TSMC has limited capacity but just like with any standard business, NVidia would have been talking with TSMC for years before manufacturing their 3000 series.
If this is true than NVidia shot themselves on the foot anyways, they may have saved money with Samsung's more inferior die (which apparently is sold with razer thin profit margins to NVidia because no one outside of Samsung really wants the die) but because the Samsung die use a lot more power NVidia had to spend a lot more money on cooling solutions for the card.
The profit margins on the FE editions are much smaller than what NVidia likes and I doubt that AIB's are happy with having to also spend more money on cooling the 3000 series (I doubt AIB's are happy in general with the crappy launch, i.e. they didn't get drivers till launch day which contributed to the crashing situation with capacitors, don't get started about the stock issues).
Also note that GDDR6X is also using more power than standard GDDR6 (and also runs quite hot, ~100 degrees even though its in spec) so this is also contributing however the situation now is that you have a double whammy.Last edited by mdedetrich; 07 October 2020, 04:11 AM.
