makes the note:

Very nice

 

Like when its off?

 

Fan stop on the reference design would be a first for NV I think.

 

FX 5800 Ultra?

 

Well, that's a name I haven't heard in a loooong, looooong time...

 

Game GPU has some benches.

Same res, same apparent settings but something is obviously amiss. Have NVIDIA even released a game ready driver?

 

Sure looks like an awful lot of power being consumed by the memory in comparison to previous cards.
My 2070 Super pulls roughly the same 180-185w to the actual GPU chip as the screenshot from the 3080.

However, only 20-25w of that is going to the GDDR6.
We know from Micron's presentation that GDDR6x is a tiny bit more efficient than GDDR6 per bit transferred.

2070 Super has 14gbps GDDR6 vs 19gbps of the 3080's GDDR6x, so a ~36% increase in transfer speed per chip, plus an extra 2 chips for the 320-bit bus for an extra 25% overall power consumption.
Therefore by my math the 3080 should be consuming roughly 70% more power for its memory subsystem. But that's only 40-45w by my calculations, far below the 75w in the screenshot.

From my understanding of Nvidia's power consumption numbers, "GPU Chip Power Draw" is post-VRM, and there are usually a bunch of things that aren't counted that will always result in a mismatch between the sum of the PCIe slot and aux power connector power draw and adding up GPU + memory power.

Fans are a big one, plus all the RGB LEDs / controllers. It's not uncommon for GPU fans to be 6-10W each.

This is the GPU of a Jedi Knight. Not as clumsy or random as a blaster; an elegant GFX card for a more civilized age. Not.

 

I am truly shocked no reviews leaked today. I figured somebody would forget to update the time on their CDN publication script or something.

 

Nvidia moved embargo date to Sept 16th

 

Yeah I know. That’s what I meant. I expected someone to screw up and publish today anyway.

 

Well, don't piss off the company that just bought another company for $40b

 

What if all the reviewers released early? Nvidia cant sue/blackball them all!!

 

New 3090 show at Amazon and Best Buy

Through shares dilution and because their EPS are absurdly too distorted

 

There was a reason for postponing of review embargo and this reason was - many reviewers didn't really get the cards to publish anything on 14th. Hence why no leaks either.
