Xeon E3-1231 vs. 4790k

post #1 of 13
Thread Starter 
I know it:
- Won't work on all 1150 mobos
- Isn't overclockable
- Doesn't have integrated graphics

I'm fine with all of that, but before I plan on buying it I want to make sure there aren't some other downsides I don't know about.

If this is for a dual gpu/triple gpu setup I would get the chip that can oc.

It will probably just be used for a single 970 or 980.

I did just notice it's 3.4Ghz instead of 4, like the 4790k. How significantly will that clock speed difference be in games?

There's a pretty huge difference in performance between the Xeon and 4790K. You're looking at a 20% decrease in performance across the board. The only reason to buy a Xeon is for ECC memory support, or dual processor compatibility with a dual socket motherboard.

I'd have to question "why" you would want the E3 vs. the i7.

I think the xeon is a good buy if do not plan on overclocking. it is the same performance as a 4770 (non K) for the price of the 4690k. In all the games that can use the extra threads it will beat a stock 4670k/4690k. Now when the I5 is around 4.4ghz it starts to match/pass the xeon with hyper threading.

So advantages of the XEON are cheaper cpu/ mobo and stock cooling to get stock I7 performance.

Only in very poorly threaded games will the overclocked i5 show a lead over the xeon at the cost of more expensive mobo and aftermarket cooler.

I know passmark is not the best example but it shows the i5 has to be overclocked to even catch the xeon

It's $80 less. If it performs a bit worse than the 4790k, I'm fine with that, as long as it performs better than the 4690k.

just when the game is cpu bound but really those are games that use few cores/threads. with asingle card will be fine except in cpu bound games which need more frequency

For single-threaded tasks and gaming, it will perform worse than the 4690K too, because of the significantly lower clock speed. For encoding, virtual machine hosting, folding, etc., the 1231 *might* perform better due to HT being enabled, but it's highly task dependent. If performance is your top consideration, I think you might be disappointed with the Xeon. Just my two cents' worth on the subject. There are Xeons that can run with the i5/i7 performance-wise, but they're not cheap.

E5s support 1, 2, and 4 CPUs on a board using the enthusiast socket (well, generally - there are some weird exceptions), while E7s support 4 or 8 and are on a different socket. E3s support just one and use the stock-standard consumer socket.

Price is likely the biggest reason, and Xeon features for VMs and ECC RAM can come in handy.

With more than four threads, yes. I'd assume they would be tied around five or six given the 4690k's higher frequency, however.

Honestly, I'm not sure. I think a 20% frequency boost would scale better than hyperthreading in most well threaded workloads.

However, most games aren't well threaded, if that's what you're buying it for.
