CPU Upgrade

[plushkinn]

I've got idea from a man that I can upgrade my i5-2400 to Xeon with same 32nm and 1155 socket compatibility.

So i got my eyes on 2 chips: e3-1270 and e3-1280, price difference on AlieExpress is about 2-3 USD. I've seen that many people get e3-1270, not the e3-1280.

I got pretty good tower cooler with 4 pipes. I can see only TDP and 100MHz difference.

 

Can you guys explain me and advise me what processor to buy: e3-1270 or e3-1280? Personally I want e3-1280.

what board is it? is the CPU in the supported CPU list?

[plushkinn]

I've already checked compatibility. But here it is: P8H67-M. Yes, CPU is supported.

Yes you can upgrade to Xeon 12xx v1 or v2.

1280v2 is so cheap, and just as good as 3770.

v2 is not compatible with my motherboard, different lithography 32nm and 22nm.

Your chipset support both 2nd gen Sandy Bridge (32nm) and 3rd gen Ivy Bridge (22nm). Xeon v2 is based on ivy bridge.

With a bios update this can happen.

Unless the motherboard restrict itself only for 32nm only.

Supports Intel® 32 nm CPU

Hmm, you're right man. Thank you. So what's the point of buying v2 instead of v1 on the same clock speed?

better preformace. It isn't all about the clock speeds. It's also about the architecture (pls correct me if im wrong)

Lower lithograpy = better temp / higher turbo.

Just looked up some prices on aliexpress. e3-1280 3.5GHz 3.9GHz-Turbo is same price as e3-1230v2 but 3.3GHz and 3.7GHz-Turbo. I can handle 95W TDP i think, cause now I have a i5-2400 95 TDP too, no more than 55C under 100% load. I still don't understand the point of buying v2 version.

it costs twice as much as e3-1280 v1. It's not about raw performance for me. I want a cheap upgrade too. So if we compare, for example e3-1280 and e3-1280v2. I think I should buy a e3-1280 cause anyway i'll be using 1333MHz RAM and it's 2 times cheaper. What do you think?

[SupaKomputa]

Yeah, it's should be okay.

So if I want to get a slightly better performance then I should think about v2 Family, right?

[SupaKomputa]

Yeah just wait for the next new CPU generation released, like after Zen 3, it will push down the price of lower generation processors.

For long term, i think you should upgrade to DDR4 system.
