![]() ![]() Pay attention to the power curves on a modern CPU or what for example TSMC states about a node improvement. This is all ignoring that 2x faster for 4x the performance is also actually a pretty good return anyway. Similarly in SPECint2017 the M1 8 cores put up a 28.85, whereas the 5950X scores 82.98. That's a hell of a lot more than 2x faster. The 5950X meanwhile puts up numbers in the 25-30k range. The M1 at 7.8k lost to the 15W 4800U in that test (talk about the dangers of a single datapoint!). Take for example the CineBench R23 numbers. You're trying to make broad sweeping claims from that one data point. The 2x number you're claiming was only for geekbench multithreaded, which was the only multithreaded comparison between those two in the Anandtech article. You're definitely going to see differences between the Air & 13" MBP as a result. the 5950X if you want to talk about 105W TDP numbers.Ĭritically though the M1 is definitely not a 10W chip as many people were claiming just a few days ago. That'd be the actual multi-threaded comparison vs. Let it run at 3.2ghz all-core instead of the 3ghz it appears to now since you've got a big tower cooler and that's 100w (6w/core 3.2ghz per the anandtech estimates * 16). Adblock for safari m1 pro#Slap 16 of those firestorm cores into a Mac Pro and bam you're at 60w. Just like it's about as irrelevant as you can get that the 5950X is 4x the big CPU cores, since it was again primarily used in the single-threaded comparisons. It's an interesting head-to-head, but that 105W TDP number of the 5950X is fairly irrelevant in these tests. M1's definitely got the efficiency lead, but it's also a bit slower and power scales non-linearly. That's a _much_ closer delta than the "105W TDP vs. In multithreaded loads the per-core power draw on a 5950x is around 6w. Take the M1's 28W under a multi-threaded load, that's going to be somewhere in the neighborhood of 4-5w/core for the big cores probably (single-core was ~10w total, ~6w "active" - figure clocks drop a bit on the multi loads, and then the little cores are almost certainly much less power draw particularly since they are also much, much slower). ![]() In fact per Anandtech's own results the 5950X CPU core in a single-core load draws around 20w. They primarily only used the 5950X in single-core tests, and in those tests it doesn't come remotely close to 105W. The entire system power of the M1 mini under load was 28W. The Zen3 processor that they are comparing it to is the 5950x - the fastest desktop processor with a TDP of 105W. ![]()
