Core i7 4930K vs. 4770K; worth the upgrade?

post #1 of 7
Thread Starter 
Hello all,
My current system, listed here:
http://www.overclock.net/t/968053/official-the-sandy-stable-club-guides-voltages-temps-bios-templates-inc-spreadsheet/9270#post_17835053

I do a lot of video editing using various tools:
- AviSynth
- MeGUI (for x264 encoding)
- Sony Vegas Pro for editing intermediate files
- Sony Sound Forge for audio
- other freeware, purchased software, but those are the main ones

I'm wondering if it would be worth the upgrade to a i7-4930K or even going with a 4770K. I've been searching the net for reviews and they all seem to vary somewhat on recomendations (some not so good).

Intel Core i7 4930K - $569.99
Asus P9X79 Pro - 309.99
Graphics card - $200.00+
TOTAL = 1,079.98 plus taxes/shipping, etc.

or...

Intel Core i7-4770K - $339.99
Asus Z87-EXPERT - $239.99
TOTAL = $579.98 plus taxes/shipping, etc.

On the other hand, is it even worth considering upgrading to an Intel Core i7-4770K or even build a second system using this CPU and use it for encoding tasks.

Sure the 4930K has 6 cores and has the "horsepower", but at a premium and varying reviews.
Or, settle for the 4770K quad core (which I've read is less overclockable than my Sandy Bridge, which is @ 4.8GHz with a Vcore of 1.432-1.440 and I love it, BTW) However, at stock speeds, the 4770K seems to outperform the i7 2600K, but then again the base clock speed of 3.5GHz vs. 3.4GHz of the 2600K.

I really wish reviewers would compare apples to apples; meaning, overclock the 2600K to 3.5GHz to match the 4770K's speed then do the testing/comparing. Just a suggestion; surely they could make the results more accurate than they are at times.

Comparing a 4930K to a 4770K at stock speeds makes sense; clearly you're comparing apples to oranges and makes sense.

Also, I read somewhere in the reviews, that the 4770K (at stock clocks) performs approx. 10-15% better than a 2600K
At the same time, the performance of the 4930K also only performs approx 10-15% better than a 2600K
I'll try to find the info and post it.
So that leads to another question, if the 4930K and the 4770K both have the approx. the same performance improvements, why would anyone more than twice the amout for a hex core instead of a quad core? I find that very interesting so I'm looking for more info from actual users as opposed to reading reviews (usually only one person's opinion)

I do not use Intel's Quick Sync at all, purely software x264 encoding.

Suggestions, advice, insight are all welcome. smile.gif

I own a 4770k, and am currently running stable at 4.7ghz with 1.279vcore. my cooler is a CM hyper 212 evo. When i was doing my research on overclocking my chip, my goal was 4.6 because a 4770k at 4.6 is about equal to 5.0ghz on an ivy bridge (this was determined by benchmarks) haswell was in a "tock" phase of intel processors (running on the same 22nm as ivy, but improved) and is 15% faster over the board.

I run virtual machines and game on my computer, currently running ubuntu 13.04, and server 2012 under hyper v (included in windows 8)

my operating system that i am doing this on is windows 8.1 RTM (msdn)

I'm not sure what you would be looking for in an upgrade, sandy bridge will probably do well for a while longer, upgrading to a haswell cpu and board will not disappoint, the OC potential is there, the trend has been that the later the chip was made the better it is at overclocking. my overclock was above average (below average voltage to be stable) until i hit 4.7, where i had to adjust more than just voltage, but still was at an average voltage for the chip. If you want to look more into overclocking haswell, this thread has been very helpful to me

I'm guessing the review you read used a benchmark that didn't utilize all cores of the 4930k. That's the only explanation I have for them being the same performance boost because the 4930k definitely is faster than the 4770k assuming you are using all cores.

As for Haswell not overclocking well, that is simply not true. It is subject to the silicon lottery just as much as all the other chips are. Haswell released just a few months ago and not everything has been figured out about it. It is definitely different in OCing compared to the SB series.

A big improvement for you would be to use a graphics card as I see you are using Intel HD3000 integrated graphics. You might want to try that first before spending 500 or 1k on a new CPU mobo combo.

I realize most of your programs are extremely CPU intensive, but they'd benefit from a dedicated graphics card wouldn't they?

i meant 3770k - equivalent ivy

That same question was asked on the Anandtech forums. There are some really knowledge-able people answering the question.

mfenn might be able to give you some good guidance. Thread.

I'm wondering the same thing...

Trying to figure out what my next upgrade should be..

Yeah, I read that somewhere, clock-for-clock the 22nm was faster than the Sandy Bridge 32nm (meaning 4.5GHz Ivy Bridge > 4.5GHz Sandy Bridge).Seems it has to do with a shorter electrical path, quicker response, etc. Power consumption was lower as is the Vcore, but the TJmax is up (about 105 deg C).

More info here:
http://vr-zone.com/articles/ivy-bridge-vs-sandy-bridge--4.8ghz-quad-core-cpu-showdown/15637.html?TB_iframe=true&height=650&width=850

The reviews I read were testing the CPU's at stock settings, so I'm assuming all cores/threads being used.

Another article:
http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/63119-intel-i7-4930k-i7-4820k-ivy-bridge-e-review.html

First paragraph,
"...You see, the i7-4960X we reviewed last week is horribly expensive and offers minimal to no performance improvements over the more affordable Haswell i7-4770K in some key areas. But Intel isn’t launching just one CPU here. The i7-4930K and i7-4820K offer similar features at prices that are well within the reach of today’s cost-conscious users...."

I've had my 2600K over 5.0GHz, just to see if it could do it, then backed it off for day-to-day work.
Yesterday I was rendering some short videos, 5-10 mins each, at 1920x1080p @ 23.976 fps. Ambient room temp was about 24 deg C and the CPU only got to 66, 73, 74, 66 deg C, which I think is very reasonable. (Corsair H100 and Antec 1200 case) Oh yeah, motherboard temp was 30 deg C. smile.gif
All videos were rendered between 24-27 fps with a crf = 19.0.

I didn't see the post in Anandtech forums; I'll have to go check it out.
It seems, to me at least, that the 4930K really only tops the 4770K in VERY heavily threaded apps like MeGUI or something similar, but even then only barely. Sure there's 2 more cores, 4 more threads, but the improvement just does seem to justify $600+ for the CPU, $250+ for a motherboard and then a graphics card.
Call me picky, but I think the 4930K or even 4960X would need to do at least 40-50% more, especially for the price you pay.

I think I'll just build a second system and divide the workload.

On a side note: I've read a lot of reviews/forums where people continue to seek out advice on whether or not they should spend an extra $50-100 on a CPU (like an i5 or i7) for gaming to get the best possible CPU for it. Really, a lot of these people are spending hundreds of dollars on a graphics card or even thousands on SLI or XFire setups, spend the extra $50-100 on the CPU and stop flooding the forums with the same questions.
I'm not a gamer at all, yet all the reviews I've read deal with how well CPU's perform in GAMES and usually one or two benchmarks on x264 encoding or something like that.
Just my little blurb... might get banned now.

Anyway, all good advice, will go check things out...
Thanx guys smile.gif
