Hello guys.

Let's say I have two cpu with same speed and cache but with socket 1150 and 1155 which one will perform better stock and why?
In example LGA1150 3gigs with 6m cache and a 1155 3gigs 6m cache both quad cores.

Thank you

I recently tested i5 3330 and i5 4460s, in regular daily usage you won't see any difference. Only thing is that with 1150 motherboard (h81) it had a newer uefi bios but the 1155 (H61) had an old ami bios.

Both platforms are outdated and won't receive bios and driver updates only exception is one bios update and that's due vulnerability.

Ok I was asking because I have both sockets. I have brand new in box a Lenovo Thinkcentre SFF M73 with a i5-4430 so I was thinking swapping the mobo in a bigger case to put a good gpu and psu. Also could just get the cpu to throw on a new board i can overclock and just get a low power cpu for the M73 and transform it into a HTPC for wife on living room tv.

The socket has nothing to do with the performance. It just designates the pin count and CPU families it supports. Performance will be determined by the CPU that goes in the socket, and the motherboard, chipset, RAM, graphics, and everything else - NOT the number of pins or the socket itself.
1150 has a better/newer artitecture so in theory should run faster.
No. The fact it is newer just means it can support newer, faster processors. But that is a function of the CPU and other components, not the socket or its pin count.

A rough analogy would be to look at the CPU socket like a lightbulb socket. Just because you have two different lightbulb sockets, that does not imply you cannot put 100W bulbs in each - or even a 150W bulb in the smaller socket. The issue is, do they make 150W bulbs for the smaller socket?

Yeah the 1150 board with a newer bios just has better compatibility with newer hardware.

Assuming exact same specs, etc, the newer CPU's on 1150 would be slightly faster

Yeah slightly being the operative word in real usage you can't spot the difference.

No they wouldn't. If the exact same specs, then they are the exact same specs.

You are suggesting one socket provides greater bandwidth over another. It doesn't.

I think he's getting at the fact that given the same specs, the newer ARCHITECTURE that accompanies the newer socket will be slightly faster :)

The newer architecture is also more efficient assuming the speed is the same etc. Intel specifically focused on efficiency for many generations. And those two sockets were during that time.

I5 3330 is 77W and i5 4440 84W the only difference between 3/4gen is a mobo with a newer bios.

I'm suggesting that the CPU's would be faster, due to a newer arch.

Then if faster, it is not the exact same specs, is it? It is about the architecture of the CPU, not the socket.

This is all about Intel choosing to use a different socket configuration for their different families of CPUs. It is NOT about the performance of the socket. If it was, then AMD would be changing socket pin counts just as often as Intel.

The newer architecture is also more efficient assuming the speed is the same
This may be true, but NOT because of the socket. Newer architectures are NOT just about the socket. They involve different (or updated) chipsets, firmware and other factors, not to mention more efficient and faster CPU designs too. The socket does not determine bandwidth or efficiencies.

Do 19 inch rims on your 1/2 ton truck mean you can haul more gravel, pull a heavier trailer, or go faster just because you have 19 inch rims instead of 18 inch? No. Not in any way!

If you think the CPU socket alone determines performance, please provide a link or links to an Intel document or documents that shows it.

Im late for questionare but what is your consumption ? Like for what purpose you are asking about these sockets. They both perform pretty well but in the it all comes to the purpose you want them to serve.

Well you have both in your posession thats great. You can compare both of them but that depends upon your usage. Clearly the later one LGA1150 will outperform in most cases.

I believe what we're looking at here are the differences between a Haswell CPU compared to an Ivy/Sandy bridge CPU, at the same clock speed. Haswell is going to be slightly faster due to architectural differences... but not by much. You also get whatever upgrades the 1150 chipset offers over 1155.

I agree 100%. But that is NOT because the socket is different which is what some are implying. The Haswell is going to be faster because the CPU itself uses a different architecture.

I also think that the chipsets that 1150 supports bring you native USB3 and SATA 3 over the chipsets that 1155 offer (if my memory serves me correctly), that alone for me would be a reason to go 1150.

Pretty sure that USB3 and SATA3 are native to Ivy Bridge chips (1155), as that was one of the reasons to move from Sandy Bridge.

1155 mobos are hard to get nowerdays if you ever need one. at least z77 ones. with 1150 you might have more luck to still get one.
