Just inherited a Dell 5820 (x299 lga2066) that came with a w-2133 cpu. What is the fastest, most cost effective CPU i can get for it right now?

So, it is going to be faster for tasks that only require up 8 cores, and then the ancient E5 is going to start kicking ass :D
we check with a benchmark using AVX512, then we see which ass is kicked.
second the E5-2696v3 don't fit in the Dell 5820 :cool:

E5 v3 went to 18 cores, not 22. Getting max turbo speed on all cores requires modifying the BIOS and that's not always going to be an option. TDP unsurprisingly also goes through the roof. You're also forgetting architectural improvements, so, clock speed is not a 1:1 match for performance. Single threaded performance is going to be much better on Skylake (or Cascade Lake) compared to some 8 year old Haswell CPUs. The W-21xx/22xx series also gets you AVX-512 if that's of any importance.
If it's heavily threaded, nothing beat the performance/price ratio of dual 2699 v3 which can be had for well under $300! and i am not talking about needing the bios hack either.

Do the -B parts work on the 5820? W-2140B (8/16, 3.2/4.2, $110 used) seems to be a good deal, W-2175 (14/28, 2.5/4.3, $290 used) seems OK as well. You're not getting a multithreaded speed demon no matter what you put in that machine but for $100-300 you can upgrade it to something respectable.

If it's reasonably complete you could also sell it and put the money towards something with a 5950X, which will kick any Skylake CPU's ass for $550.

I have no idea how strict dell enforces oem cpu. someone told me 2696 v2 worked on dell before. so i guess it's ymmv.
The system i got came with a w-2133 and 4x 8GB ECC DDR4 but seems like 3 of the 4 are bad? i will have to test those 3 on another system to make sure they are really bad.
It also came with a quadro P2000 which is pretty nice still. Also came with two 500GB intel sata 6gbs ssd. I am sure i could sell it as is for close to $500.

I have a W-2140B in my T5820, works no problem.

I really want to buy something to upgrade that cpu from w-2133 but the current 2066 cpu price so far is not much of a bargain...lol.... the w-2133 cpu seems to be fairly decent anyway. I just spent $270 on two 2699v3 and $300 on i7-12700k.

I think i just need to get a WS with the intel Scalable then I will have all the different WS type...lol...
