极客湾里的跑分29k?看来和anandtech的测试水平差距还蛮大的。
anandtech的原文是:
Restricting our Ryzen 9 7950X processor to just 65 W in comparison to leaving power settings untouched, the CineBench R23's multi-threaded test performance is impressive, a score of just over 31K. For comparison, the Intel Core i9-12900K only managed just under 27K at default settings, which shows that even when restricting the power proportionally down to 65 W, there's still plenty of performance available in multi-threaded situations. For reference, restricting the Ryzen 9 7950X to 65W only loses around 18-19% in CB23 MT performance; very impressive.
我没看出anandtech在哪里提到65W是tdp功耗而非实际功耗,相比极客湾,我更相信anandtech一些。
这还是zen4采用5nm ccd+6nm IOD的芯片互联封装的前提下。即使采用极客湾的视频内容,比照3.2/20 core的M1 u 24k的R23得分,和7950x 3.9G/16 core 29k的R23得分,M1u的成绩是375分/核/G时钟,7950x是465分/核/G时钟。抛开M1 ultra无比庞大的计算管线、巨大L2 cache和统一封装在一的高速ram,效率上M1 ultra已经不及zen4内核了。 |
