moved from an Intel E5-2620 v3 (6 cores/12 threads) to an Intel E5-2630 v3 (8 cores/16 threads) on Windows 8.1 Pro.
Memory is 64/96Gb quad channel, ECC/Reg DDR4-2133. My PPD has actually stayed flat even though I'm completing 4 extra units concurrently. any ideas as to what's going on here? cheers, D |

They both have a base of 2400 MHz and turbo up to 3200 MHz. And the same TDP of 85 watts. Perhaps the 6 core can turbo higher when running the WCG.

1. - a new WUs on a new proc have to be confirmed (except in FAHB project)...so wait a while!
----------------------------------------2. - a 2620 is a better at single core processing...look here: http://cpuboss.com/cpus/Intel-Xeon-E5-2630-v3-vs-Intel-Xeon-E5-2620-v3  |

E5-2620 v3 (6 cores/12 threads) turbo to 2.6 fully loaded
----------------------------------------E5-2630 v3 (8 cores/16 threads) turbo to 2.6 fully loaded How many days running the new setup and is this the same ssd? It can take a while to settle even if you are running the same single project, the cpu % and max cores available is auto  |

@OldChap,
same system and everything. nothing new has been added or removed except for the processor and the memory (moving from 4 * 16 per channel to 4*16+4*8 per channel). @KliK, probably true. I'd wager, though, that the increased L3 cache (5mb or so) in addition to the additional cores should outweigh the overall performance of the 2620. lol. anyway...good link. I run this fully dedicated to WCG right now so, 16 work units at a time. cheers, D |
