i7-4930k vs i7-4790k in games?

[djp_20]

I currently own an i7-4930k but don't know if I should switch to an i7-4790k and a new motherboard. I'm only interested in gaming performance. The i7-4790k already has high stock fequencies. By default it does 4.2 GHz when all 4 cores due to it's turbo boost and 4.4 GHz by default when 2 cores are loaded due to it's turbo boost, and theres the increased IPC as well, but I lose out on 2 cores compared to my i7-4930k. My i7-4930k by default turbos to 3.9 GHz only when one core is loaded and 3.7 GHz when 4 cores are loaded. Would gaming be much better on an i7-4790k over the i7-4930k? Any games that an i7-4930k will run better than an i7-4790k. I already have almost one of the best performing video cards for gaming currently( GTX 780Ti), so I don't see any point in upgrading to a little faster video card. How would these 2 CPUs compare to each other in Far Cry 4, Assassin's Creed Unity, The Crew, and Call of Duty AW, games I plan on purcashing in the future?

Why would you downgrade?

The single core performance of the i7-4930k is better. Therefore also better for most gaming purposes.

Anyways the CPU isn't your bottleneck. You won't get any FPS difference from swapping other.

Your graphics card is much more demanded on for gaming. However that isn't a bottleneck either depending on your resolution - 1440p? The GTX 980 will give you slightly more performance, but won't really shine unless going for higher resolutions. You would only gain 2-5 FPS more in most games at 1440p. Not worth it, in your case.

Far Cry 4 will run fine... well polished and looking awesome!

AC: Unity will run like dog at 920p, locked at 30FPS, and riddled in graphical glitches... however, that's because it's a bad console port (in which the console CPU was bottlenecked and therefore they had to limit that game down), they never removed the limits on the PC version. It's just a terribly coded game and unoptimized. Ignore that game and boycott it.

4930 is a 2011 cpu
you cannot upgrade to a 4790k without changing the mobo

keep your 2011 build, its better than 1150

for a cpu upgrade go to a 4960x

That's why I said a new motherboard as well.

[Azza ☠]

But why? I still don't understand...

Does your PC has an issue of some sort? Bottlenecking at the hard drive? Get a SSD (Solid State Drive). I don't see any reason for it to bottleneck elsewhere.

Then do nothing. Any gains you may possibly get will not even remotely be worth the dollars spent. I seriously doubt there is any game out there that will max out a i7-4930k. If you want to spend money, get a GTX 980. Your CPU isn't the problem at all, even in the slightest.

No point at all to upgrade your CPU (or more like downgrade).
Also not much point to get GTX 980, performance gain over GTX 780 Ti is not worth the money either.

i7-4790K would be a downgrade.

If you are worried about frequency make sure you have a good high performance cooler then learn to tune your CPU.

You can probably reset the turbo to do exactly the same as the i7-4790K if you want. To reduce power use and temperatures you could also disable 2 core, underclock (downclock) 2 cores or simply have their Turbo speed be set to the default non-Turbo, effectively selectively disabling Turbo.

Basically what I'd saying is you can tune your i7 into a i7-4790K or better by overclocking or a combination of overclocking and underclocking/disabling.

Personally I'd just leave it at stock settings and keep on cruising though. Very nice CPu at stock speeds. If the tuneup makes you feel better and you don't care that it may void your warranty then go right ahead though.

Well 4.4 GHz on all cores seems to be the ceiling for my chip but I can't really tell for sure because I only spent a few minutes testing at 4.4 GHz and I don't want to operate my chip at the edge of stability for everyday use. Also I noticed that manually entering the turbo settings for each core in the BIOS brings a small performance hit, at least in some tests in 3Dmark 06. For example manually entering 39 39 38 37 36 36 is a little slower in some tests in 3Dmark 06 than the stock turbo on Auto which is 39 37 37 37 36 36. 39 39 38 37 36 36 should be faster than 39 37 37 37 36 36, or at least never slower. Even setting the stock turbo multipliers manually to stock turbo settings is slower for some reason in 3Dmark 06 than turbo in the auto setting. Does it sound like a BIOS issue? So manually entering the stock turbo multipliers does not seem to be performing as it should be.

Also is it common in Grid Autosport to once in a while get a 0.5 second stutter during a race even on a high-end system? I tried it on a HDD and and SSD and that does not get rid of that stutter. A dedicated sound card does not get rid of it either.

My PC:

i7-4930k
32GB DDR3-1600
GTX 780Ti
512GB SSD
1 TB HDD
SB X-Fi Titanium sound card
Windows 8.1 Pro

Try downloading Intel's tuning utility and using that instead of BIOS.

If it was a AMD Chip I'd be recommending AMD Overdrive but Intel has their own I just don't recall the name. Intel Extreme Tuning Utility or something.

Also when overclocking play with the power a little to see if giving it more power on the overclock will improve the performance. It can be stable but still losing performance if there is not enough power running through it I think.

Just don't fry your chip.

I was recommending turning down 2 cores to turn up the other 4 so as not to change your total power use. Also to allow the software to switch turbo from core to core to prevent making hotspots or taxing any one core too hard. I can see how turning up all 6 would be a lot harder on the chip than turning down 2 and up 4.

never use software to overclock cpus/ram ect..
do it the old fasioned way, in bios

[Rove]

Why?

Sometimes sftware might be able to do it better, specially if it's from the CPU manfacturer (AMD or Intel) themself. I mean what if the BIOS is buggy? What's wrong with software?

[djp_20]

I tried ITX instead of the BIOS and same result, manually entering the multipliers is slower in 3Dmark 06 when entering the stock multipliers and a little higher multipliers. I also had this issue with an i7-4820k. I don't know if some kind of performance feature in the chip get's disabled if entering multipliers manually rather than auto. I think I"m going to stick with settting the turbo to "sync all cores" to 3.9 GHz, the max turbo for my chip, that way instead of 3.6 GHz on 6 core loads, I will be getting 3.9 GHz. I've done lots of stress testing at the speed without issues yet and core temps don't exceed 73C during stress testing at that setting.

Turn off turbo boost if you're overclocking. Just change your multiplier to whatever you want your max clock to be, speedstep will take care of bringing it down when you don't need it. Also set your vcore manually.
