Question Upgrade Sandy Bridge to Haswell CPU?

[DanBurn]

I have a CPU-upgrade question. I have an old (2012) HP desktop machine. I have upgraded this old PC every which way over the years (drives, fans, PCI cards, GPU, power supply, RAM etc), but it still has the original i7-3930K (Sandy Bridge) CPU. This is now causing me a problem. I am a heavy Adobe Lightroom and Photoshop user, and the versions of these that just came out are no longer compatible with this CPU. Specifically, I need support for Advanced Vector Extensions 2 (AVX2). Sandy Bridge CPUs only support AVX, not AVX2. My understanding is that I have to jump ahead to at least a Haswell processor to get AVX2.

So, setting aside the "buy a new computer" idea, my thought is to get a Haswell CPU (eg: i7-5820K, 5930K, 5960X, etc), and try dropping it in. I don't know if that will work because 1) I'm not sure the processor/socket are compatible and 2) I'm not sure the processor/Mobo are compatible. Maybe there are other issues as well, IDK.

Regarding the socket: my i7-3930K uses the original LGA2011 (AKA Socket R), but most Haswell CPUs are LGA2011-v3 (AKA Socket R3). I don't know the issues with forward/backward compatibility with these socket subtypes.

Regarding the Mobo: this is an HP OEM Pegatron 2ACE, and there isn't much info online about this, such as at www.cpu-upgrade.com.

So, that's where I am at. Can anyone provide any guidance on this? Thank you.

The corresponding Asus motherboard also accepts some Xeon processors, what exactly do you want?
From what I know, I think that if you have Sandy Bridge you can only go to that one.

Not sure what you mean about the ASUS/Xeon references. My question is basically: is it possible to upgrade from Sandy Bridge to Haswell, and if so, what issues do I need to investigate.

I think you can't.

i7-3930k xeon counter counterpart equivalent looking right now.

But still no AVX 2

I think Haswell-e (x99 chipset) required a whole different motherboard from Sandybridge (x79 chipset).

Haswell-e, unlike sandybridge-e had a FIVR. Haswell-e also uses DDR4 not DDR3.

I believe the best you can get for x79 is the Ivy-Bridge-e CPUs.

This being an HP system complicates things to a degree.

I am not the end all be all of knowledge on those "X" series HEDT chips, but if they follow the same tik-toc it should not also be compatible with 5xxxX CPU. With it being a proprietary system the easiest thing would be to try and find a cutsheet on the computer directly from HP as the guide. If you don't see that CPU on that cut sheet it is no. In the case that it was a standard format motherboard from one of the various vendors it would have a CPU support document to look at.

Just for fun, what is the exact model of this HP? Not real sure how much help even that would be given they like to have the "Service Code" which is usually stuck to the case somewhere.
