Intel Xeon E5-2628L v2 vs E5-2643 v2

post #1 of 4
Thread Starter 
Hi!

I'm riding a dedicated server at home for storage, NAS and virtualization. A friend sold me a Xeon E5-2628L and E5-2643 v2. What is better?

E5-2628L v2: 8 cores / 16 th, 20Mb L3, 2.4 GHz, 70W

E5-2643 v2: 6 cores / 12 th, 25Mb L3, 3.8 GHz, 130W

The first is much cheaper than the latter. Is there much difference in performance?

Thanks

I mean, you can kinda see the differences yourself. tongue.gif Eight lower-frequency cores vs six higher-frequency cores. It depends on what you're doing. My vote is to stick with the 8-core unless you really need single-threaded performance. It uses less energy and should perform about as well when all cores are used.

But both are dual-socket, Ivy Bridge-based Xeons. They're the same silicon, so any differences come down to frequency and how many cores got lasered off. If you have a dual-socket board, I think both of those can be used together, even though they're mismatched. However, the 8-core will be restricted to six and the high-frequency chip will be forced to downclocked; all CPUs need to run the same configuration.

Thanks for reply thumb.gif

No need any professional, it's just to learn Windows Server, Proxmox, etc and simple RAID-Storage/NAS. So I think it's best to buy the 16-core and buy a small graphic card with the price difference (no integrated graphics). You agree?

But they work individually, right? I mean I need a motherboard with chipset X79 s2011 and it works with only 1 CPU. In addition, X79 are Quad Channel, that means that necessarily need 4 slots of RAM?

Thanks

How much is he selling them for? You might be able to get a cheaper single-socket 6-core or even quad-core if you don't really need the performance. And when you say "16-core," do you mean "16-thread" as in the 8-core Hyperthreaded chip, or did you add a 1 in front of "6-core"? headscratch.gif

All dual-socket means is that you can use up to two CPUs on the same motherboard, but you can of course use less. (As an aside, I'm not sure if the opposite is true, if you can use two dual-socket processors in a quad-socket motherboard, even if just two are used.) Quad-channel memory is supported, yes, but it isn't necessary to populate all slots. Just one stick in single-channel is enough to get it to boot and run. There isn't a huge performance benefit, generally speaking, from quad-channel vs dual-channel in things like games. X79 is a "prosumer" platform and not really a gaming platform.

Do keep in mind that X79 won't accept ECC memory and you'll need the C602 server chipset, assuming you want or need ECC of course.

And yeah, GPUs are cheap. I picked up a functioning Quadro 600 for $30 - needed its cooler for a project - and I'm sure you can find cheaper ones. If you get a server motherboard, you might find an ASpeed AST2400 integrated. That's a 2D GPU with 16MB of VRAM. You, uh, might want to get something a bit less awful though.
