cinebench multithreading, ryzen 8 cores 16 threads sample, 2557 points, intel 9900k 8 cores 16 threads, 2040 points, now calculating cinebench single thread based on single cores, ryzen, 2557 / 8 = 319.6, intel 9900k 2040 / 8 = 255, from official review from techpower up on 9900k , multithread = 1914, single thread 218, if we use 1914 / 8 = 239 on single thread. For ryzen to have a score of 2557, single thread has to be fantastic, close to 300 on cinebench single thread benchmark, that is really incredible.
Another example is ryzen 2700x, official results on techpowerup review, cinebench multithreading, 1819 points, single thread 179 points, 1819 / 8 = 227 and on cinebench single thread amd has only 179 points instead of 227 which means, 227 - 179 = 48 points which is around 25%. So if we factor the 25% on ryzen 3 sample we will have the final cinebench single thread result of = 242 points which is still better than the i9 9900k from intel = 219 points, It is ryzen that good? yes it is, lets hope price will too.
