Intel Kaby Lake Pentium CPU

Post by Kittyhawk »

My question is about the Pentium G4560 CPU. It has 2 cores and 4 threads.

How much PPD can it give when CPU folding only (no GPU folding at all). Please mention the operating system (Windows version, 32 or 64 bit, etc.), and system configuration (how much RAM etc.) if possible.

I've tried searching online for info on CPU folding PPD of Intel G4560, but was unsuccessful.

It can only fold using core_a4 and not use the new faster core_a7 because G4560 has no AVX. I guess 25k PPD.

This is incorrect. The client can also fold on this CPU using Core_A7. It will download the SSE2 version of the core instead of the AVX version.

You are right. But the non AVX core version runs slower. And that is why I mention G4560 lacks AVX support

Yes a bit slower, but faster than the A4 core on the same work.

Via NaCl you'll get around 2-3k PPD nowadays.
NaCl is reporting 10x slower than 1 month ago.

NaCl points were, in fact, reduced not long ago but I don't think it was anything approaching 10X. NaCl is intended to have lower points than those of the regular FAHClient and that was not always the case due to an error in assigning early points.

The average points drop (looking at the graphs on extremeoverclocking) is 3-5x lower now than a few months ago.

The points are lowered, and the WUs are more lengthy nowadays (take about 1 hour to finish, vs a few minutes per WU before).

The slowest readings I saw last week (1,6k PPD) vs the highest ratings 2 months ago (30k PPD) are closer to 20x slower now than before.
But that's measuring the extremes.
I knew they had errors in point calculation, as those 30k WUs would only be credited for about 10k.
The current slow WUs are also credited accordingly (2,5k PPD on my system); which is about 4x lower than I have been seeing.

Nacl at the moment has a mix of slow and normal WUs; so not all WUs are affected.

I am asking about desktop client (fah-installer_7.5.1_x86.exe), not NaCl (Chrome) client.
I am not using Chrome browser.

The non-NaCl WUs have a benchmarking procedure which can never be made perfect for all classes of GPUs -- although it has a better degree of sucess for CPU project.

If the GPU projects which were benchmarked a few months ago happened to be higher than they should have been and that has been corrected, maybe that happened.

The goal is to AVOID points inflation where next month's new project might earn more PPD that this month's -- but as I said, there is no ideal system.

The new version of FAHClient DID NOT alter the points. The points are awarded based on the speed you complete WUs using FAHCore_a* or FAHCore_2* and there were no updates to those FAHCores within the past few months.
