Both CPUs are very similar, all core turbo on both is 2.5 (I would ignore the 2.0 and 2.3 values) . Cinebench score on the V4 is around 80-100 points more due to the architectural improvements of broadwell since again both turbo at the same all core turbo.Intel Xeon E5-2658 v4 QS 2.3GHz LGA2011-3 14C Compatible with X99 i7-6850K 6900K | eBay
Has anyone tested one of these?
QS
1792cb score.
2.3ghz- 2.8ghz turbo.
Would this chip outperform the 2683 V3 OEM? Single core boost is poor, especially compared to the likes of the 2686 V3( Dam i wish those chips were still around!), however, the higher clock speed 2.3ghz vs the 2ghz of the 2683 & 2686 should help multicore performance.
Single core performance on the other hand the V3 sligtly edges it since its 2 core turbo is 3.0 as opposed to 2.8 on the V4. In my testing between V3 and V4 I found out clock for clock a V3 Xeon clock at 2.6 is equal to a 2.5 V4 (100mhz give or take).
However V4 CPUs handle AVX a lot better than V3 and do not downclock as bad as the V3.
Question for you, will this CPU be paired with an X99 motherboard or server board?
V3 CPUs overclock better than the V4 variants. The busses are a lot stable on Haswell than they are on broadwell. On the V4 CPU I tested I could not get higher than 102 on the BCLK, both Haswell chips I had can do 105 easily.
I currently have my main rig with a 2683 QS tweaked and stable and get a Cinebench score of 1820 (love the multicore performance). But it is also real good for gaming as well, tested against my old 5820K overclocked to 4.4 I only got a 10 -15FPS hit in worst case scenario and around 5 or less in great threaded games.
Out of the 2 I would personally choose the the V3 OEM do the price, however if I was going to pair it with a server board and do heavy AVX workloads I would choose the V4.
