I got lucky and picked up a 3070 as I happened to be online when new stock was added to a site I visit. But essentially... things aren't looking great. My target was a launch 3080 or hold out for the...

I was asked to compare non-512 performance of Rocket Lake. To disable AVX-512, is all I need to do add the following line to local.txt?
CpuSupportsAVX512F=0

If so, the results were unexpected....

I chose 128k FFT size because it fits one per core with room to spare, and is about the smallest size I'd encounter in my areas of interest. Ram doesn't matter for that.

Once I'm done with some...

11700k just arrived and dropped it in and ran P95 bench pretty much as 2nd thing after CPU-Z to check CPU model and ram setting.

For 128k FFT tasks (one per core) it confirms the data I got...

Zen 3 Epycs run to 280W TDP, and not limited to the top core count parts. Guess that is just where servers are currently.

Other sources show 60MB L3, or typically 1.5MB/core of L3 plus 1.25MB/core of L2 which is non-inclusive so that will also count.

The cache is unified... as much as it was since Skylake server...

Ok, for wider context I looked up on paper how the GPUs compare.

I ended up re-ordering the 11700k after all as I now have an alternate way to obtain it. This time they have shipped it arriving should be tomorrow.

While looking for a new mic at an online store by chance I saw they had Rocket Lake listed as in stock, so I should have a 11700k tomorrow. I didn't get the mic.

Faster ram always helps in this scenario, but with a H370 mobo I believe you're limited to whatever the official speed is supported by the CPU. It would have cost more, but perform better to get a...

Time for a Rocket Lake speculation thread? I'd caution that if the implementation is single unit, the throughput may be no better than AVX2.

Interesting point. It might not necessarily be halved due to various changes in the way Zen 3 works, but I take the point that we have more cores hanging off a single pool.
