Curious, with this small variations in performance why do you guys care?

Are you doing something that matters?

Or, more of just "I have the fastest" ?

Genuinely curious :) as I have lots of not needed performance ;) ;)
No issue here, just interesting (to me) that the V2's (2667/2687w) trade blows with the 5960x (Haswel) and the 6900K (Broadwell) is only a bit of a step up. Ryzen 7 falls right in with these too.

Edit: Also, re-encoding a lot of h264 to h265 (archiving TV shows my wife does not want to delete). Handbrake does not seem to scale that well over 8 cores.

you consider the e5-2696 v2 that are currently on sale for $300 or less per cpu?
The 2690 V2 is probably the best for 10c/20t along with the 2697 V2 for 12C/24T. The others are usually clocked lower for 10c/20t or 12C/24T but prices are dropping for those as well in addition to the 2690/2697 V2. It's a shame though that Ivy Bridge-EP only went up to 12C/24T unlike the Broadwell-EP series which went up to 22c/44t.

Cool, good info!

Not to get too far off track, but what do you suggest for being able to rip and encode from 3 DVDs / Blu-Rays at once? I put together a 4U for that 2 years ago, then re-used parts, and the chassis and BR drives remain, would like to rip a bunch of (purchased) kids shows off DVD, as fast as possible :D and ebcide def. h265

No good way to do multiple that I have tried. I usually just use both my wife and my workstation to rip/reencode tv series manually. It is a pain especially with some of the big box sets. Most of the TV shows she won't be able to tell the difference between a reencoded h265 and the h264 encode. Hell, she doesn't seem to be able to tell the difference between a DVD and BR :p

Most movies I just rip as is and don't reencode, with a good sound system I keep the HD audio tracks and I have a nice 1080P projector so it all looks good.

A spot price check on ebay right now shows that the e5-2696 v2 is $300 while e5-2697 v2 oem (not qs) is still $600+ while even the qs is like 400+$. e5-2697 v2 definitely doesn't worth the premium over e6-2696 v2 when you take into account the turbo factors which will kick in anytime you put the cpu to work.

As far as e5-2667 v2 goes, was hoping that you can open up multiple threads or even running multiple instances of the app to encode several files at once. Because the e5-2696 v2 right now with the going price of $290-300 is really the best bang for buck for v2 cpu once you get several threads going.

Taking into turbo factor at max multithread usage:

e5-2696 v2: 12 x 3.1ghz = 37.2 ($290-300)
e5-2667 v2: 8 x 3.6ghz = 28.8 ($360-380)


There is no comparison as you can see when using all cores....

You are right there. PassMark - CPU Performance Comparison

For high core count V2's the 2696 is a great deal.

don't forget also that e5-2696 v2 has higher TDP than e5-2667 v2 so it will be able to run a lot of those cores at higher numbers longer. if your app is strictly single thread, then you shouldn't even consider a xeon cpu. but if you can use more than 6 threads, or can open multiple app instances, e5-2696 v2 is the best bargain for v2.

You tried handbrake? I thought handbrake does use multithread to a certain degree. but you can also open multiple instances to use more threads better.

edit: looks like e5-2667 v2 tdp is higher at 130 and e5-2696 v2 is 120

Both are 130W parts. The machine it's used it will be seeing both single core and multi-core workloads. Right now the E5-2667 V2 is sitting in a Lenovo S30 with 32GB of 1600mhz DDR3. It runs great but the stock cpu cooler seems a bit anemic, although it has not throttled due to heat yet.

sorry i misread the line in wikipedia page. the TDP for 2696 v2 is 120w and 2667 v2 is 130w

Going by Cinebench R15 the 2697 V2 is around 1500/120 which really means you give up about 15% single core to gain 15% multi-core speed. If this machine was just going to crunch videos, the 2696 would be a clear winner, but general use favors having the higher speed on a few threads.

Oh yeah, good resource for info on the chips (except the ones like the 2696) https://www.intel.com/content/dam/w...cification-updates/xeon-e5-v2-spec-update.pdf

That's based off current prices. The E5-2697 V2 months ago were selling for several hundreds if not more. Prices are coming down but upon closer look the 2696 V2 actually has slightly better turbo bins when lower amounts of cores are used. For example the 2696 V2 can do 3.1Ghz with up to 8c but the 2697 V2 can do 3Ghz with 7c. So it looks to be an interesting processor especially since it's a custom OEM one.

Yeah, cant wait to get my pair in the mail in 2 days to test it out. 2697 v2 is still significantly more than 2696 at this point. i cant imagine what that old price was like.

going to sell my old pair of e5-2670... they barely last 1 yr...lol

The 400mhz difference in single core makes enough difference that the IPC gain can't make it up.

I have been surprised that the V3/V4 cpu's don't have something with higher clocks.
so why would anyone getting a 2667 v4 over 2667 v2 then?

@wildpig1234 To add to @TType85 AVX2 and 2x memory capacity maximum
don't know if i completely bought into the ddr4.... sure, if you ever come to max out the memory and if you do then you have the money and wouldn't really be asking much about cost

but for the majority of us who never come close to the need or have enough money to be able to max out ddr3 that you would actually need to have a ddr4 board to be able to hold more ram, ddr4 just just a huge cost step up for minimal benefits and bandwidth over ddr3....
