Xeon E5640 to 2500k / 3570k worth it?

[Aphexis]

Seeing how this stuff has come down in price.. my Xeon is clocked in at 4.1ghz, i have a Sapphire Fury Nitro arriving tomorrow and i am thinking of pulling the trigger on a new CPU cooler and a new chassis from OCUK, but is it worth it to change platform?

I will gain some IPC, better instruction sets, but lose Hyper-threading and lower price / perf.

Thoughts?

I wouldn't (even if it was cheap), I'd only switch to a 6 or 8 core.

I will see how the Fury does tomorrow, i have some demanding games i can throw at my CPU.

The XEON has no issues hitting 100FPS easily in GTA V but that's with a GPU that can't enable settings that increase CPU load, though draw distance is maxed out.


EDIT with Sandy and Nehalem at clock for clock settings (4ghz)

Nehalem has basically zero performance loss vs SB-E?

Context is kind of important, firstly the ones where they are equal are ones where the Graphics card is holding the system back, secondly that clock for clock comparison shows Nehalem at or near it's overclocking limit while SB-E has around a GHz more to go.

I'd probably go with a Ryzen 1600 and a B350 board. Either that or a £50 6 core 12 thread Xeon.

Obviously, that Westmere EP is slower at stock than a Sandy Bridge desk, has lower IPC and probably the SB will overclock higher. Depending on your config, you might lose out on either memory capacity or bandwidth ... but there are very few situations in which you would be CPU-bound by the Westmere but wouldn't be by the SB. The Ivy Bridge chip will not be likely to overclock as high as the SB one, so I'd leave that alone.

The 2011 DT platform is a decent step-up from the 2010 server/workstation one, though, and you're likely to notice it feeling snappier (based on my experience moving from X58 to H67).

Would I take that step in 2017 though? Are you getting it for free?

You can get them for £25 now. If you don't mind the wait for Korea

How would 6 slower cores help?

So the machine is overhauled and has been up and running solid and strong, CPU is now at 4300mhz pushing that Xeon even further, i can go higher but right now i just don't have the patience, plus i am enjoying how quite the CPU cooler is in silent mode. Also the memory is running way out of spec but stable.. which is a miracle, Hyper X Fury Blue 8 GB 1600mhz rated at CL11 .. which is bad.. is actually running at 1636mhz CL9 with volts at 1.6.

Picked up a few bits from OCUK, and Amazon, this is how it's looking.

The person i bought the Radeon from actually bought it from OCUK originally, he left his receipt in the packaging lol.


I tested DOOM, when i leave the frame rate to run rampant it easily slides along at 120-155FPS but GPU usage never hit's complete maximum so i do have a very small bottleneck but i am also running the GPU at 1160mhz which puts it near a stock GTX 1070. Usage sit's around 85-90%.

Also the CPU temps you see in the video are with the tiny Noctua ITX cooler not the one i have installed now so they are relatively high. And CPU at 4.1ghz.

I actually cap my FPS since i don't run a high refresh screen anyway but the performance it is putting out is very admirable.

Other games like Deus-EX MD in DX12 run amazingly well.. barely any CPU usage.

Some benchmarks.
