E5-2696 V2 CPUs for $325!

[Storm-Chaser]

Whats the benchmarks?

I was expecting the seller not to accept my offer.....lol... oh well.. It would've been nice to be able to use this in the lenovo s30 but that's not the case. I do have two D30, one with dual 2695 v2 and another with dual 2667 v2. I guess this will replace the 2695 v2 cpus and then i can put those 2695 v2 which are not oem into my s30.

2695 v2 is also 12 core 24 threads but the overall single and multicore speed is basically mediocre.
2680 v2 is only $55 now...lol... for $55, i don't think you can find a new intel or ryzen cpu that can beat the 2680 v2 in multicore performance either.

Looks like the price drop in v2 cpu is making them a bargain again if you willing to use older MB and hardwares.

I have more questions here but no time to respond ATM!... Very good steal with those CPUs! had to ask first about your RAM setup. (Here is a little challenge for you) Are you about to go 8 channel with your Lenovo D30? Because you will need at least 16 memory modules running at 1866 MHz to run "level" with my z820 memory bandwidth

My dual 2696 v2 is inside a box with the asus z9pe-d16 MB with 256GB 1333 ram 16X16GB . so it's definitely not as fast as yours memory bandwidthwise

This is the benchmark fo my system. Not the best but it gives a rough idea of the performance: Asus Z9PE-D16 Series Performance Results - UserBenchmark

Ha Ha...I've been there. That's how I wound up with a pair of E5-2651 v2 for my Asus Z9-PRD12. I wanted to upgrade from a pair of E5-2630 v1, and while I was more concerned about core count than speed (they are 12 core), I was thinking I'd probably want something faster than a 1.8 Ghz base clock. But, I figured it wouldn't hurt to give a pretty low offer of $25 each just to see what happened....

At least you can brag that you have a pair of 12 core cpu...lol... but that cpu is not much than a ryzen 4500U 15W 6core 6 thread notebook cpu
Btw, what case are you using for that Z9-PRD12 MB?

My son and I use it to experiment with VMs, hypervisors, OSs, hardware/software configuration, etc. We don't do any "regular work" on it, and don't use it for data storage. Yeah, its weak. But unlike that Ryzen, we've got 64 PCIe lanes and 160GB of RAM to work with

Yeah, I wanted to mention the 2680 v2 is a great chip. One of the best chips in the 2600 series family, striking an excellent balance between core count and frequency. Definitely a great buy right now.

I recently LOST a pair of 2600 v3 chips (ill get back with the exact model later). I'm really annoyed about that, I really dont want to talk about it lol. It was one of the 12 core chips and for some reason very cheap on ebay right now, despite excellent performance numbers that eclipse every single v2 chip on the market.. So I will be re-visiting that family as well, getting two more of those.

Oh, didn't see that question earlier....we've got it in an ancient Supermicro SC933. So, lots of room. Replaced the old PSUs with a single fixed Supermicro PWS-605P that was an almost perfect match size wise. With active Intel BXTS13A CPU coolers and a decent fan curve, its actually pretty quiet.

FYI Guys these two CPUs are still pretty cheap and pretty powerful especially if you combine two of them.
The 2696 v2 runs at identical single core turbo speeds as a 2697 v2, and since it has a 100mhz boost in ALL CORE turbo speed, the 2696 v2 is actually the better processors, especially when you factor in a lower TDP of 10 watts for more 100 MHZ.

According to some quick calculations, these run about $100 on ebay right now, with the 2697 about $15-20 more!

I can definitely confirm that they do run at 3.1ghz all-core speed as well as 3.5ghz single core speed. If you have a good (doesn't even have to be great or liquid or anything fancy) cooler, they will stay at 3.1ghz all day long for max multicore tasks.

Yup. That's exactly correct. No matter how much I can throw at it, given a very good cooling system it will NEVER dip below 3.1GHz all core. Also with a very good water cooling system your turbo operation will be much more aggressive. So while it will hold 3.1GHz with air cooling for the most part, you will be missing out on some very slight performance advantages vs water cooling. (at least in my research)

 

[Storm-Chaser]

The lower TDP would make the 2696 less likely to be able to keep up the turbo multiplier and max usage compared to 2697. so the 2697 would still likely be faster most of the time.

My z820 rig with two 2696 processors says this might not be true. Bench marks are pretty much spot on between both processors. Both long and short duration benches as well. You can't just assume the higher wattage processor is going to have better turbo clocking. It's only a 10 watt difference.

A more reasonable conclusion is that the 2696 and 2697 is the same except that cpus with higher leakage current (and thereby higher power use) get sold as 2697 and the better cpus off the assembly line get sold as 2696 and are allowed to all-core-turbo a bit higher on account of their energy efficiency.

Yes, this is the most reasonable conclusion I have seen offered for this discrepancy between the two chips relative to performance.

I cant confirm this right now, but I have a hunch that all OEM processors in the 2600 v2 series have no limit on base turbo clock. ie. 2673 v2

 

[wildpig1234]

I thought 2697 were supposed to be the "better" one since it's more expensive than the 2696 and also have more MB compatibility and is not OEM and is guaranteed to work on more MB?

Yes these attributes you listed likely make it the more attractive option. But if you are looking at raw performance, I think that's the concept we are dealing with here. They are very very similar processors, nearly identical, regardless of our semantics here. Although cost is relative. The retail chips always run a little more expensive than OEM processors. In general terms, of course.

 

[Storm-Chaser]

just made an offer for two 2696 v2 at $79 each. With tax to my state on ebay (you suck for starting to collect tax on EVERY state), the total came out to be $169 and change for two 2696 v2. So not too bad I guess.... YMMV

1950X multicore performance for $169. even one single cpu multicore performance here is much better than anything you can get from intel or amd right now for around $80. Not to mention the saving on ram price...lol..

Yeah you know whats up! Pretty sick processor right?

This may be a bit vague, but here it is: I have a dell t7610 with two 2695v2 and 256gb @1600 doing
double precision calculations in all 24 cores 24/7/52. what is one to expect from an upgrade to two
2697v2? any guesses or benchmarks?

Probably not worth the hassle and cost of upgrading.

Marginal improvement in multicore. Here's the bench for 2696 vs 2695 v2 . If you can score a pair of 2697 v2 with great price and able to sell your 2695 v2 at good price.

Thanks. The answer seems to be "dont bother".
The attractiveness of the v2 is/was the cheap(er) memory. Otherwise
a current cpu from intel/amd with fewer cores would easily outclass
any two v2s.

Depends on workload and other system hardware as well. And definitely not easily outclass two of them. Two 2696 v2 processors will actually edge out a core i9 extreme 10980XE in CPUz multi-core benchmark. That particular chip has 18 cores and 26 threads.

The memory performance is still pretty impressive as well. This is my z820 after populating all memory slots with DDR3 1866MHz RDIMMs, for a total of 16 memory modules, 8 memory channels and 64GB. This is the maximum supported memory speed of the chipset. This is the theoretical limit of ram performance/bandwidth in a z820 system. So as you can see, this RAM setup will very quickly out gun all dual channel kits (usually by a factor of two) and the vast majority of state of the art DDR4 quad channel systems as well.
