RTX 3070

Code: Select all

GPU Variant: GA104-300-A1
Launch Price: 499 USD
TDP: 220 W
Memory Bus: 256 bit
Bandwidth: 448.0 GB/s
Base Clock: 1500 MHz
Boost Clock: 1725 MHz
Memory Clock: 1750 MHz (14 Gbps effective)
Shading Units: 5888
L1 Cache: 128 KB (per SM)
L2 Cache: 4 MB

Vs RTX 2080 Ti

Code: Select all

GPU Variant: TU102-300A-K1-A1
Launch Price: 999 USD
TDP: 250 W
Memory Bus: 352 bit
Bandwidth: 616.0 GB/s
Base Clock: 1350 MHz
Boost Clock: 1545 MHz
Memory Clock: 1750 MHz (14 Gbps effective)
Shading Units: 4352
L1 Cache: 64 KB (per SM)
L2 Cache: 5.5 MB

The things that stand out here, are:
The 3070 over a 2080Ti has a $500 lower base price, little slower memory, 200Mhz higher boost clock, 1500 more shaders, and a larger L1-cache (not sure if a higher L1 cache is going to improve folding speed).

Might replace my two 2060 cards with one of these. If I can cobble something from scraps I might also run the 2060s in cold weather.

It would be particularly interesting to see how this GPU would do against the Radeon 6900 or 6900XT.
While the Radeon may be faster in gaming, I doubt it will be faster in folding or compute.

If it weren’t for the software upgrade that allows better use of CUDA cores, I think that the new AMD cards would have been more competitive. As things stand...

[HaloJones]

if only it was possible to actually buy one!

[MeeLee]

The AMD GPUs have very few shaders (Cuda Cores for Nvidia). Like the 6900XT only has 5120 shader units, which is less than a 3070 (5888 cuda cores).
That's 15% less cores.
Those cores are running higher though, at ~2100Mhz (est) continuous boost, vs 1,825Mhz boost on the 3070 (which is 15% faster).

It'll really depend on the architecture.
Sure Nvidia has CUDA, but removing CUDA, from those core numbers, it appears that the highest end $999 AMD GPU running at around 300Watts, might perform similar to the $500 225W lowest end RTX 3000 GPU.
I'm sure AMD must have some other forms of optimization in there, as for OpenCL compute applications at first glance it would seem like a very poor choice to go with AMD!

I'm not touching anything AMD in terms of GPU's (especially for my Fedora PC's, which will be updated to Fedora 33 within the next few days), until AMD unifies their workstation and gamer/average consumer GPU drivers for the major Linux distributions; or provides more precise installation/updating instructions.

In the meanwhile, I'm adding NVidia GPU cards that I can afford to my systems to be ready for the next sprint(s).

AMD CPU's = Good; AMD GPU Driver Installation Instructions for Linux = Good Grief!!!

3070 doesn't really have 5888 cores unless you accept their redefinition of the word "core".

For ~half the price the guys over at techspot found the 3070 to be as good as the 2080 Ti. With lower power consumption.
Sounds tempting.

I didn't say they had 5888 cores. I said they had 5888 cuda cores. Which, they call their own shaders 'Cuda Cores'.

I don't know what the optimal setting for the 3070 will be, but I do know that unlike the 2000 series GPUs, that all benefitted from lowering TDP, the 3000 series are not going to boost as much when GPU temps drop.
Meaning, you might run that 3070 at maybe 10-20% lower TDP, but unlike a 2000 series GPU, you'll lose much more than just 2% of performance.
The 2080Ti actually runs best around that same 190-220W. So in that sense they're pretty similar as well.

[MeeLee]

Here's a guy claiming he was able to successfully shave 100W off of his 3080/3090, by tuning it.
Essentially running ~1700-1800MHz boost at just over 200W.
Apparently it is possible to lower power output, and increase clock speed in a similar manner as on the 2000 versions.
On a 3090 it does seem to make a lot of sense, as it's processing data nearly 3x faster than a 2070 at stock settings.
