How can i get accurate information about a CPU that isnt benchmarked?

[Lord Szechenyi]

Hi.

I want to upgrade my pc, it has a 2011 socket, so that's what i'm searching for.

i found a CPU, the E7-2890 v2, and according to intel it's an LGA2011.

however it isn't benchmarked in any reliable benchmarking website (cpubenchmark.net and the like)

so how can i know if it is a good cpu or not?

That is a server cpu

It's a 15 core 30 thread ivy bridge CPU.

So that means if you're doing work that needs lots of cores it will be decent but if you're gaming it won't be any better than an ivy bridge i7 running at low clock speeds.

You can kinda extrapolate how the CPU performs if you know what your workloads respond to. 

 

Double check the E7 can be used in your intended system. I think they had different requirements than the more regular E5 line.

yes i'm fully aware of that

my pc is a z420 workstation, which is a server pc.

what do you mean by "requirements"?

i thought it only needs to have the same socket

Wasn't easy to understand since you didn't specify

i kinda do both, but my current cpu is only 4 cores, so this will be a big step up anyway.

thanks, so although it only has 2 results, would it be safe to assume that

A the e7-2890 v2 is more powerful than the 2850

B that it would probably have a score of at least 13000?

C that this CPU will work in my motherboard

Don't assume but check is what I'm saying. The E7 CPUs supported up to 4 way use, so they are a more different than the common E5 supporting two. Wouldn't want a situation where you have a mechanically compatible CPU but it doesn't work as the mobo doesn't support it.

how can i check if its compatible?

but it doesn't matter anyway

i was asking about the 2011 socket, so that's all you needed to know anyway

Check your motherboard and/or system documentation.

You need a compatible socket, chipset and support in BIOS. See recent news about AMD CPUs where older MBs aren't going to support Zen 3 despite them still using AM4.

Not really, I have a 2011 socket, but I don't think my motherboard supports 4-way server CPUs, my motherboard doesn't support EEC ram either, which is likely what you will want with a server CPU.

Asking about the motherboard, given the post above mine, was a legitimate question.

 

As to all we needed to know...well given that people are trying to help you for no benefit to them, perhaps being snarky towards them isn't the brightest idea, because I don't see why I should add any of my knowledge to your thread for you to be snarky to me because you didn't like the impertinence of my question.

[Brennan Price]

So the thing is... And this annoys me... Is that no-one here had first asked which PC you are using or had asked which socket motherboard you are using (Before they had given you the benchmarks that is)... There are various iterations of the 2011 socket and so not all of the CPU's are compatible. Based on the fact that you have said your computer is an HP Z420... This would be socket 2011 V2, therefore the maximum processors that this PC can handle are likely E5 Xeons. Having looked at the manual, this is what it states about your HP Z420 workstation: 

 

from the manual:

 

Intel

®

Series C602 chipset with:

●

Support for the Intel® Xeon™ Processor E5-1600 Series and E5-2600 Series,

including processors up to 150W

●

Integrated 4-channel memory controller

●

Microarchitecture improvements

●

Large L3 cache for superior performance

●

Intel QuickPath Interconnect (QPI) connects processors and I/O controller with speeds

up to 8 GT/s

 

So with this information... You now know that you cannot put an E7 Xeon into your PC, which for some reason others have not yet mentioned. 

 

The PDF below also from HP's website states which processors will work fine in your computer.

EDIT: If you would be so kind as to mark this as solved.
