It is actually interesting, i mean the OctaneBench average result as well, given the fact the 2070 chip (TU106) is half of the 2080Ti one (TU102) - even though not exact half, since 2080Ti is slightly cut, its 2304/4352 = 0,53...
Anyway, if the 2080Ti scores on average 300 points, which i can confirm, one would expect the 2070 to score somewhere in the 160 -170 range, not 220.
This most likely points out to the way higher GPU clocks for 2070, probably consistently above 2GHz, and i have to wonder about VRAM speeds as well. From my limited experience with 2x 2080Ti on stock settings, during OctaneBench test they hover aroud 1800 MHz on avg (the upper one more in the 1700-1800s, the bottom one 1800-1900)...there is not room for trying any OC in my case, as the temps are already 78C and 84C respectively...so its very likely i am leaving quite a lot of performance on the table and could be looking at maybe close to 700 points with better cooling, rather than current 600-610 - judging by those 2070 results. Cant really see any other explanation.
Actually looking at the OctaneBench now, i see 2x 2070 scoring those 433 OB points, while result right above is 2x2080 with 439
. Since those 2070s have 79 percent of 2080´s cores, they need to run 20 percent faster than those 2080 to make up for that. I guess, that is plausible, with 2080 at cca 1800, and 2070 at 2150....
On another note, i tested 2018.1 XB1 speed against 4.00 in one of my own scenes, not really complex exterior architecture model with daylight/HDR environment without any foliage or any other light sources...and the result was once again interesting. I had set up 2 cameras, each one from different angle and tried how long it takes to get to 500Ms for each camera. It turned out one of them was actually very slightly slower, 35 seconds to 36s in case of 4.0, the other one though saw the time cut by 10s (from 48s to 38s in XB1). Tried only single run, so not really most scientific, but still, perhaps i would get similar result if i repeated the test. Have to wonder if the speed increase in the second camera angle is down to RT cores coming into play...and why only one of the cameras got faster....
