> MacBook Pro with M4 Pro is up to 3x faster than M1 Pro (13)
   > (13) Testing conducted by Apple from August to October 2024 using preproduction 16-inch MacBook Pro systems with Apple M4 Pro, 14-core CPU, 20-core GPU, 48GB of RAM and 4TB SSD, and production 16-inch MacBook Pro systems with Apple M1 Pro, 10-core CPU, 16-core GPU, 32GB of RAM and 8TB SSD. Prerelease Redshift v2025.0.0 tested using a 29.2MB scene utilising hardware-accelerated ray tracing on systems with M4 Pro. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.
 

So they're comparing software that uses raytracing present in the M3 and M4, but not in the M1. This is really misleading. The true performance increase for most workloads is likely to be around 15% over the M3. We'll have to wait for benchmarks from other websites to get a true picture of the differences.

Edit: If you click on the "go deeper on M4 chips", you'll get some comparisons that are less inflated, for example, code compilation on pro:

    14-inch MacBook Pro with M4  4.5x
    14-inch MacBook Pro with M3  3.8x
    13-inch MacBook Pro with M1  2.7x

So here the M4 Pro is 67% faster than the M1 Pro, and 18% faster than the M3 Pro. It varies by workload of course.

No benchmarks yet, but this article gives some tables of comparative core counts, max RAM and RAM bandwidths: https://arstechnica.com/apple/2024/10/apples-m4-m4-pro-and-m...
