First, I know we can't compare R20 and R23 scores -just making clear on that.
In R23, render test is set to 10 minutes by default. And if single rendering is finished sooner, cycle will repeat until 10 minutes pass. That is reasonable time at which CPU temperature stabilizes enough and we get real life scores. R20 can do the same if we set time manually to 600 seconds -which I did.
I won't talk about scores for my CPU. Let me show how long it took to finish each test on both Cinebench versions:
R23 MultiCore: 632sec for 17 passes
R20 MultiCore: 634sec for 18 passes (17 passes would be 634x17/18=599sec)
R23 SingleCore: 1002sec for 2 passes
R20 SingleCore: 935sec for 2 passes
As we can see, R20 is in both cases (Multi & Single core) almost exactly 6% faster.
I must say that was quite a surprise for me.. because a while back (after R23 was introduced) there was mentioned that R23 is using more recent compiler (which assumes better/faster). But as it seems, that's not the case -newer "better" compiler (that Maxon is using) is slower.
Now I wonder.. is that only the case for AMD CPU's (which I have), or is that also the case for Intel CPU's? Anyone interested to fire up Intel CPU on Cinebench R20 and R23, to confirm?
