4770s vs 4770 (non-k)

Hi all,

I'm building a new SFF system and I'm wondering if anyone has done a comparison between the s and non-s versions of haswell. How much loss is there given the lower based clock?
 
Different procs, but in my HTPC, I had a 4570S and went to a 4670K. The S seemed very unwilling to budge off of its 800MHz downclock. I have no real concrete proof, other than my experience with both procs in the exact same machine doing the exact same thing. Even stock, the 4670K was noticeably faster / smoother opening things, manipulating media etc. it was also more willing to upclock itself when the need arose. However, stock and stock, the two were a good 8 degrees apart at idle. I'm running the 4670K at 4.2 Adaptive, Balanced, daily now and the experience is better.

When I ran the 4570S in Performance mode (3.6) it felt better and was noticeably faster on some stopwatch type tasks. Problem is, it never wanted to get up there on its own under Balanced. The power saving was just too aggressive for my tastes. Happier with the 4670K.
 
What sort of cooler are you using and what sort of temps do you get as a result. This system will be a work station and I know I'm going to appricate a smooth OS.
 
In my HTPC, I'm actually using a low-profile Noctua. It's technically not rated for an 84W proc. However, since my HTPC never goes postal on all 4 cores, it's never an issue. Only something like the new Haswell Prime will overwhelm the cooler. The hottest it has gotten was around 55 degrees... If I had room for a bigger cooler, I'd use one, but I don't and it's fine. It idles in the high 30's / low 40's.
 
I have an i7-4771 and it runs fine on a 160 watt picopsu with an HD7750, so I'm thinking it is pretty far under the 84W rating. Worked fine with the stock cooler as well, hottest it got was around 88*C under IBT. Given all that, I would have a hard time justifying the S version.
 
Good to hear. I've got a thermalright AXP-100 which I hope takes the load. I'm also looking at the E3-1245 v3 xeon now since it's $10 less than the 4770... for some reason.
 
The S should stand for "smokescreen".

I went that way thinking it would run cool because of the lower rated wattage.

For the things I actually do, this wasn't a good choice.

When I found my S wouldn't run prime95 28.1 without instantly throwing up in-program errors, I called Intel and they asked me to send it in. They sent me back a brand new S in box and I sold it on eBay. Bit of a loss. Not much happier with my 4770K since it doesn't want to OC much at all. Guess I picked a weird time to come back to Intel from AMD but at the same time, even stock the 4770K is faster than the S, idles like 10 degrees cooler (loads are worse) and blows my last cpu (Phenom II 960t run x4) out of the neighborhood.
What I am noticing is that I have a lot less money around since I went Intel, since for whatever reason it made me obsessive about upgrading the rest of the machine... again, and again.
 
A hint to op>

Phoronix recently had a review (linux of course) of a new I3-4130 vs an I5-2400s (and a few other processors). The i3 with 2 less cores & LESS power usage beat or tied it in most benchmarks. Direct comparison of i3-4130 & i5-2400s

Get the normal proc & downclock it as you want. Linux has many great utilities for this (cpufreq-utils, cpupower) and I'm sure windows does as well. You can also undervolt if you want and probably get similar power usage.

I'm in the process of moving from my 1090T to an i5-4570 :) This is my dual boot box (my main desktop is a phen2-940 am2+) and I really hope it will drive my 6850 crossfire a little faster in windows 7/gaming.
 
I ended up going with the E3 and an gigabyte H87 itx board. Thanks for the input all.
