I just read the chart, the RTX 4070 TI Super is 15.67% faster than the RTX 3090 for OpenCL, it might not be enough of a reason to buy an RTX 4070 TI Super, and the RTX 3090 has more ram, the only reason to get a RTX 4070 TI Super would be much faster ray-tracing, but you get 16 GB of VRAM instead of the 3090 24 GB, it really depends on the kind of work you do!

Like I said, it's a toss between VRAM, rendering power, and price, I choose the RTX 4070 TI Super because I felt that it was the best bang for my buck, 16 GB of VRAM filling most of my needs, but if you need more VRAM, than either stick to the RTX 3090, which is still a great card BTW, but you'll miss on render power, the RTX 4090 is also an option, of course, but they cost double the RTX 4070 TI Super!

There are rumours about an RTX 5xxx series coming out by the end of the year, the RTX 5090 could have as much as 32GB of DDR7 VRAM and be 70% faster than the RTX 4090, you might want to wait for more info on those, but so far it's only a persistent rumour, no official announcement from Nvidia!

Thank you kindly. So in summary 4070 should be in general faster than 3090 in karma xpu but in other areas of Houdini where OpenCL is used - 3090 would be faster?

Here is an OpenCL benchmark...
