Huh, that's a weird one.
 What exponent is running on the second worker? Assuming both are 2880K FFT size, they should both fit with a little spare place into 50 MiB, as 2880*8 gives about 22.5 MiB of L3 cache needed for the test. |

3990X benchmarks
I've asked paulunderwood to run a few throughput benchmarks on the 3990X. Many thanks for that.
I attached graphs of the results. The first one is normalized throughput benchmark from size 64K to 19200K for 1, 2, 4, 8, 16, 32, and 64 workers, all using 64 cores in total. Normalization was done by the following formula [normperf = throughput * ln(FFT size) * FFT size / clock speed (4,1 GHz)]. You can see performance drops, which show when the cache runs out. The second graph is a zoomed-in part of the first one so that the differences can be seen better. ZIP file contains the values used, as well as original graphs, in an Excel spreadsheet. Manual data analysis showed some weird behaviour. Due to not having enough time now, they will be mentioned in another post. |

Is anyone able to get data for Intel 11th Gen, maybe 12th Gen? If so, would that person be so kind and benchmark it for different FFT sizes (maybe even some really small ones)? Thanks in advance.

AMD just announced a mid-range 8 core CPU with 96MB instead of 32MB L3 cache: Ryzen 7 5800X3D.
Will be interresting how this affects large FFT performance. [1] https://www.anandtech.com/show/17152...us-in-2022-ces |
