XPS One 2710, i7-3770S Support for AVX2?
This machine has been working wonderfully for me. It runs Windows 10 just great and It has the latest BIOS A14 as well as SSD drives for storage and cache. Boots fast and runs great.Video card performance is pretty good as well with a NVIDIA GeForce GT 640M.
I am in need to find a way to enable AVX2 support that seems to be absent from my current configuration capabilities. Anyone out there can think of compatible CPU options to be able to upgrade to?
Thank you very much for any thoughtful replies.
Cheers!
Giorgio

avx but no avx 2 mentioned in i7-3770s spec
Instruction Set ExtensionsIntel® SSE4.1, Intel® SSE4.2, Intel® AVX

when you look up spec for i7-4770, avx2 is mentioned
Instruction Set ExtensionsIntel® SSE4.1, Intel® SSE4.2, Intel® AVX2

i7 3770 is ivy bridge cpu, lga1155 socket.
i7 4770 is haswell cpu, lga 1150 socket.
lga 1155 and 1150 sockets are not compatible.
haswell architecture new features compared to ivy bridge:
New instructions (HNI, includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, ABM and FMA3 support). https://en.m.wikipedia.org/wiki/Haswell_(microarchitecture)

Wow, thank you so much for the thorough response.
I could not find information about the support of the i7-4770 processor by this motherboard chipset under the latest and last BIOS version available A14. Do you know where I might find this info assuming the processor form factor is compatible for a straight swap for the 3770?
Thank you again for taking the time to response. More Kudos coming your way.

Maybe I found an answer to my own question. Looks like there is no support of anything past the 3770 series processor for this board (H77) no matter the BIOS rev?
https://ark.intel.com/content/www/us/en/ark/products/64018/intel-h77-express-chipset.html
as the 4770 processor requires a gen 8 or 9 chipset

Darn it. Thanks for pointing me in the right direction. Looks like I've reached the end of what can be upgraded on this machine.

Not to necro this thread, but there's another way to get things going. Lookup up Intel SDE (Software Development Emulator.) It's meant to let people test new instructions that don't exist yet on the current chips... but it emulates loads of instructions, you can run on some old thing with only SSE2 and it emulates SSE3/4/4.1/4.2, AVX, AVX2, AVX256, AVX512 and every other instruction that's been put in chips in about the last 20 years.
I've used it a few times, and Intel's obviously put in a lot of work on it, the speed's not bad -- I had secondlife on some old thing when they switched to requiring sse4, and running the newer version under sde ran about the same speed as the older one (that didn't require SSE3/4). In other words, you don't get the speedup of the new instructions (since that's not physically possible) but I actually got very little slowdown either compared to using the best available natively supported instructions. (like, running something that needs AVX2 it's probably just going to use 2 AVX instructions to simulate the AVX2 instruction, rather than doing some super-slow full emulation of the instruction.)
