AMD Radeon RDNA2 Navi (RX 6500, 6600, 6700, 6800, 6900 XT)

Seems so.
Honestly the interesting part will be NV21 vs NV33 because those have similar enough config.

Little to no impact on those iirc.

I mean it mines ETH a bit faster but not that much faster.

 

Adding to that: HWInfo has a sensor readout for GeForce RTX 3k cards called "GPU FBVDD Input Power" where FB probably stands for Frame Buffer, i.e. graphics memory.
On an RTX 3090 in our lab, this goes to roughly 120 Watts during ETH mining, to 80 watts during Furmark (and AIDA64 memcopy test) and 41 watts during an ALU throughput test (also most AIDA64 ALU tests).

 

120W for the GDDR6X?
Is that really possible?

 

Clamshell being messy.

 

Well 3070ti for example uses around 70w more than 3070, which very little of that is likely coming from the core difference.

 

It's the core voltage:

 

Taking those graphs at face value, it certainly looks like voltage is a contributing factor for sure, since they're running at the same nominal frequency.

 

It's unlikely, that this is G6X devices alone. But maybe it's grouped with the memory controllers inside the GPU. Nvidia did mention, that one of Ampere's things was a "dedicated memory system rail".

 

They tested one 3070 versus one 3070Ti?

How do they control for sample variation?

 

How many samples do you think reviewers get? Especially at the moment? How many would be considered enough to average out sample variation?

 

Only cryptominers can afford doing it these days.
Lol.

 

Hardware Unboxed (Techspot) said in a recent video that they are constantly turning down video cards for review...

I'll leave the answer to that question for the statisticians.

Possibly the only way to get a decent answer is to put the same watercooling loop onto each card in turn to approximately normalise GPU, VRM and memory cooling. But PCB design variation is going to make that tough. Any other ideas?

Does HWiNFO read "silicon quality" on Ampere and RDNA 2 (it used to on older GPUs didn't it)? Does that meaningfully correspond with voltage/power/clocks?

 

Didn’t silicon quality end with Maxwell on Nvidia’s side?

 

AMD Radeon Pro W6800 review - AEC Magazine
June 18, 2021

 

It's only 5% more MH/s for 5% more memclk (62,7 vs. 59,7) on a 6800. If you turn on fast timings for both clock speeds.
Very boring scaling, just linear.

 

Starting to see stock of 6700xt's around £750

 

Good that stock is starting to trickle in. Bad that it's still insanely over priced. I can barely justify spending MSRP for these new gen GPU's so I might be waiting a while for an upgrade.

 

Mining is finally on the decline but that still won't solve the overall everything shortage.
Think G6 spot prices are going up too.

 

I've given up on this generation.

I decided give Red Team a punt this time rather than Green Team as they are playing silly buggers.

But I can't find either so I'm going to wait for RX7800XT and GTX4080 to see what looks good at that time. In the meantime I'm going to keep my money, they seem to have enough of other peoples to keep them going.

 

For RDNA2 it won't, for others though it well may.
