I7 2600k @ 5Ghz or 3930k@ ~4.5Ghz

post #1 of 14
Thread Starter 
I'm currently running a 2600K at 5.0 Ghz with 1.41v. I can pick up a 3930k with motherboard (Gigabyte G1 Assassin 2) for a *very* good price but I'm pondering whether as to how much benefit I will see.
My computer use is varied but I do a lot of encoding to Mpeg4-ASP (Xvid) and Mpeg4-AVC (x264) also a bit of photo editing and gaming as well as music production. Will probably also run some VM's..

Has anybody done something similar or that can give me anecdotal advice?

I went from a 2500k to my 3930k and saw a huge difference, granted your 2600k is better than my old 2500k but is there a reason you would only be running the 3930k at 4.5? My 3930k can overclock much higher than my 2500k ever did.

For encoding, editing, VMs the 3930k will be quite a bit better. How much you'll notice it will be up to you and how much you actually utilize it and what programs you use.

Personally, if you can get it for a *very* good price then I say do it.

~4.5Ghz is just an estimate as most of us know, even an average overclock is not guaranteed. Also I would have preferred to have stayed with Asus for overclocking as it seems to get better results than the Gigabyte G1 even though the G1 is ~£300 here in the U.K.

All depends on what you plan on running on it. If you are going to game, then odds are MHz > Cores. If you are going to do Folding or use applications that will actually take advantage of 12 threads, then the 3930K will do better.

3930 rocks.

I found it not only destroys heavly threaded apps but gaming seems to be smoother and all around better experience. even with a lesser clock

Don't hestitate to grab some memory that can max the boards capabilities

It does make a difference dispite popular beliefe, especially in a quad channel set up

Mine goes safely and reliably to 4.6GHz @ 1.35V under a halfway decent air cooler. Temps are my limit. I'm sure if I had a more capable cooler I could push it higher. But just the same, it's high enough for me.

Kind of off the subject here a little, but I also have 64GB of RAM for a use with a RAM drive, but I leave a lot left over for Windows to use. For example: doing a whole thorough virus/malware scan on 300GB and the OS takes 2 minutes thanks to SuperFetch. That's compared to a few hours on a more typical PC that has a HDD. I have about 29GB cached in Standby RAM by SuperFetch.

And yeah, the ASUS X79 boards are great.

I would be going from 8GB to 16GB (4x4Gb) to take advantage of the quad-channel. Mpeg4-ASP isn't optimised for multi threaded use but Mpeg4-AVC is so I might loose out slightly in one area and gain in another. I'm hoping that the extra cache will also help things along a bit.

I'd do it. While your 2600K is no slouch by any means i think now we are going to see more games use more cores (ie Crysis 3) as the next gen systems roll out. Not only that but a 3930k handles multi-GPU solutions better than the 2600k does and delivers better performance.

From the looks of this thread, you probably know more about CPUs than i do lol tongue.gif enjoy your beast if you do pick it up thumb.gif

If I do get it I will make comparisons with my current system and keep which ever suits me better. I'll report back.

I've got the 3930k and did some tests for the things I use my computer for. I overclocked the 3930k to 4.5Ghz just by changing the multiplier. I haven't touched anything else and it's stable at that speed with 1.32v. It should probably go a little bit higher if I start playing but just for preliminary testing I'll use that..

Encoding exactly the same file showed a 26% improvement. Far Cry 3 also showed a slight improvement with the average FPS going form 77 to 82.

It looks like I'll be selling my much admired 5.0 Ghz 2600k...
