During the multi-core tests, the "small" M3 Pro did very well and came between the old M2 Pro with 10 cores and the M2 Pro with 12 cores and even so, the distance between them was never larger than 10 % in both cases. The old M2 with 10 cores also consumed about 27 watts. While the full version of the M3 Pro with 12 cores uses 26-27 watts under maximum load, the smaller 11-core model only uses ~23-24 watts. As a result, its maximum memory bandwidth is now 150 GB/s instead of 200 GB/s. Furthermore, its memory interface speed has been reduced from 256 bits on the M2 Pro to 192 bits. The cores themselves have the same tech specs as the other M3 SoCs, as the performance cores are capable of reaching up to 4.056 GHz and the efficiency cores can reach up to 2.748 GHz. Together with the 6 E cores, this means it is an 11-core CPU. On the new M3 Pro, there are now two clusters with 6 cores each - although on our smaller variant, only 5 of the 6 P cores are active. The M2 Pro's clusters (performance and efficiency) consisted of 4 cores and on the smaller 10-core model, only three of the four P cores were active per cluster - together with the 4 E cores, this resulted in a total of 10 cores. The new M3 Pro's core configuration has changed compared to the old M2 Pro.
