@seacrest I've found very good review of Lovelace GPU cards on DAZ Forum. Good reference for whom looking for upgrade new cards or consider to replace old ones.
Since it is harder to compile all these numbers up, I scrounged and gathered up some numbers for GPUs that might be of interest now. Most of these are in the recent DS 4.21. Please remember these numbers are not absolute, and can vary between scenes and versions of DS. This just a general idea of what to expect.
Iterations counts
3060 6.6
4060ti 7.23
4070 12.71
4070ti 14.175
4080 16.5 to 19.6
3090 16.7
4090 28.5
A5000 14.36
Titan RTX (Turing) 8
Putting all these in one spot really shows how far apart these GPUs can be in the Lovelace line. It is frankly surprising just how wide the gaps are.
The 4060ti is really close to a Titan RTX, which is faster than a 2080. On its own that sounds pretty cool. Until you see the rest of the numbers.
The 4060ti is somehow roughly half as fast as the 4070ti. The gap to the 4070 is also pretty high.
The 4090 is a ridiculous FOUR TIMES FASTER THAN THE 4060ti. This also means the 4090 is TWICE as fast as the 4070ti. The 4070ti is literally half, offering half the VRAM and speed. Wow.
The 3090 is 2.5 times faster than the 3060, so the gap was much smaller for Ampere, especially considering this is the 3060 and not the 3060ti.
Hopefully this might help some people who are looking to buy a GPU for Iray. The 4060ti 16gb is an interesting card, but the price is still pretty high. The 4070 is only $100 more and much faster, but you do give up 4gb of VRAM. The 4070ti is twice as fast as the 4060ti, which is just crazy. The 4080 is about 2.5 or so times faster. And the 4090 is on another planet. You really need to know how much VRAM you are going to need to justify a 4060ti over a 4070.
Honestly this all just makes the 4090 look like a deal, LOL. What madness is this? But that isn't really news, there have been reviews joking about this. It is just crazy to see the numbers spell it out this way.
