- masklinn 4y agoThe CPU cores of the M1 and M1P are exactly the same (just with different mixes, and different boosting behaviour on the E cores). If the M2 has 18% higher PPW, and keeps the same TDP / power draw, that's 18% higher performances (remains to be seen whether it's across the board for E-cores, or for P-cores) it's about 25% below the 6+2 M1 Pro, and about 70% below the 8+2 M1P. At least looking purely at the CPU.
- paulmd 4y ago14" MBP gets the M1 Pro/Max, not the base-tier M1. The M1 Pro is a 6+2 configuration, so it will have a little bit of an edge in core configuration, but Apple claims 18% faster on this generation, which might cancel out that edge a little bit (I'm guessing slightly slower still, but close). The M1 Pro does have a 40% larger GPU, but the M2 is 35% faster (again, taking Apple at face value) so it should again be similar-ish in gpu performance, very slightly slower (135/140 = 96% as fast). The big difference is still that M1 Pro gets support for much larger memory, and the 14" has a much better port configuration, the 13" is basically still the same old chassis with USB-C and the touch bar, just updated with a newer processor.
- stetrain 4y agoM1 Pro is either 6+2 or 8+2 depending on which model you select.
- cehrlich 4y agoM2 will be faster in single core, M1 Pro will be faster in multi core. Taking Apple's 20% claim at face value: Geekbench Single Core - M1, M1 Pro: 1700, M2: 2040 Geekbench Multi Core - M1: 7700, M1 Pro 8-core: 9000, M2: 9200, M1 Pro 10-core: 12400 Of course we'll see M2 Pro/Max sooner or later, which will presumably match M2 on single core just like the previous gen.
- joakleaf 4y agoApple's 20% was for multi-core.
- skavi 4y agoThe M1 and M2 have the same number of cores. I suppose the fabric could have been improved for the M2.
- sgerenser 4y agoMulti core uplift will be a bit more than single core, because the “little” cores improved more than the big ones. 18% multi core uplift, but only 12-15% single core. Weak cores might have increased by 25% or so but they’re still much slower than the big cores so don’t affect “single core” performance.
- ohgodplsno 4y ago>Taking Apple's 20% claim at face value: Which you shouldn't. They are, once again, using performance per watt. Nothing guarantees that it even runs at the same wattage.
- randyrand 4y agoM1 Pro is 35B transistors, M2 is 20B, fyi.
