I5 3570k - Gaming Performance

Hello,

I've recently been overclocking my chip to 4.2ghz and 4.4ghz (Haven't pushed further yet) just trying to see how much of an impact it has on gaming performance and the games that I've been trying is:

Guild Wars 2 and World of Warcraft

In WoW the difference from stock clocks to 4.4ghz was like 1 fps difference? if that, I think 4.2ghz was actually worse by 1 fps!
Haven't tested GW2 yet properly but it seems similar also, no major increase in FPS from CPU overclock.
Strange because I thought these two games were CPU-Intensive rather than GPU!

My question is,
Is it worth overclocking my CPU for gaming performance, like will it ever give me a huge increase in FPS like 5+ at least?
Going to 4.4ghz has given me 1 fps, if I hit 4.6ghz would that give me 2fps? haha

Anyway resolution is 1080p and using a HD 6870 graphics card.

Thanks.

No, overclocking will not increase FPS in gaming 90% of the time.

That CPU is fast enough at stock clocks that 99% of graphics cards will be the bottleneck.

Your graphics card is low-end, that is what will bottleneck you.

The CPU is already good enough, so OC'ing doesn't do a thing. If you want a CPU-intensive game, try BF3 on a 64-player server.

A 6870 is only a bit worse than a 560 Ti, so it's not exactly "low end", but I agree that it's the bottleneck here, especially at 1080p, since that's almost completely GPU bound.

no 4ghz is more than enough for games in 2012, get a better graphics card such as the 7xxx amd series or nvidia gtx 6xx series if you want an improvement in the fps but a 6870 is pretty decent i have a gtx 580 and it does great

So what your saying is.. the HD 6870 bottlenecks my CPU at 1080p? what if I had a 680 GTX or something along those lines, then would my stock CPU bottleneck the GTX 680 at 1080p?

I notice you've got the same CPU and cooler as me.. but your running at 4.7ghz is that so you don't bottleneck your GTX 670? or would you get the same FPS with your CPU at stock clocks with your GTX 670?

GW2 is new, so issues are to be expected. Your CPU is good, so your GPU bottlenecks in WoW. Overclock it. A 680 for WoW and GW2 is overkill, but the i5 won't bottleneck it.

Pretty much. 1080p is a lot to ask of a 6870 (even if it is a pretty good card, though WoW shouldn't be as much of an issue as GW2).

Yes. A 3570K is pretty much the strongest gaming CPU you can buy (within reason, since a 3960x would be better).

Wow thanks for information it's much appreciated, so even with a GTX 680 and I overclocked my i5 it would give little to non FPS increase on BF3 64-player server!

It might but it still wouldn't be much because, especially in BF3, 1080p is almost totally GPU bound.

Edit: If you were playing at 720p or less, then it would help a good bit.

BF3 is GPU bound in SP, but in MP, it is pretty much the most CPU bound game ever (I don't mean that literally).

That's true, to an extent (especially 64 player), but 1080p is still quite hard on the GPU, no matter how you slice it. A 64 player server might put more stress on the CPU, but the GPU is still gonna have a tough time.

Was just playing BF3 multiplayer with my CPU at 4.4ghz.. not 64-player but like 20-30 something players and my CPU cores were all pretty much under 70% load does that mean bottleneck? or is 70% decent.

also I know this isn't the right section but, CPU was hovering around 55-65c and max of 70c are they safe?

even if it was a complete CPU application, what were your expectations? Please do math.

stock is 3.8ghz. 3.8->4.4 =15% increase.

if you were getting 50 fps, at best you could only expect 58fps.
If you were getting 100fps, at best you could only expect 115fps.

You need exponential leaps usually to feel an gaming "upgrade", that's why the tom's articles often say you need to go at least 3levels higher to make a difference.

if you want double fps, you should have the expectation that you got to double your speed, ya?

Stock is not 3.8GHZ.The turbo clock is 3.8GHZ and it only boosts to that when a single core is used.It clocks a bit lower with two cores used and with three it's almost at stock speeds.But since most games use four cores the 3570K will be clocked at 3.4GHZ at stock.

And now to the question.
Overclocking a Intel Core i5 doesn't increase performance because even at stock it's more than the game actually needs.If you had a AMD Athlon like me you'd see a 30% FPS jump with a 30% CPU OC :D .

So what your saying when you overclock, your really only overclocking the turbo boost? (Using offset mode btw) so the CPU won't run at my 4.4ghz unless turbo boost kicks in? and Turbo boost only works on 1 core... or did you mean only kicks in when one complete core is 100%

If all cores are 44x, Turbo's basic function is, for all intents and purposes, disabled. Since you're using offsets, and (I imagine) you still have SpeedStep enabled, it'll run anywhere between 1.6 and 4.4, but it'll run 4.4 with 1 core OR all 4 cores in use (not just one), no matter the load, since they're all at the same multi.

Right now, no stock i5 is a bottleneck to virtually any card (maybe a 6990/GTX 690), doesn't matter if its a 3470 or a 3570. Personally this was why I saved $100 and went with a 3470 and an H77 mATX board. You want more gaming grunt upgrade the old 68.

Like the others have said, your GPU bottlenecks you 99% of the time so overclocking now won't help, but when in say 2 years you do get a new GPU then overclock so the CPU doesn't bottleneck the GPU.

I just used tmonitor while playing World of Warcraft to show what my CPU cores are running at while running around in a high populated area.. (It's a recording of the cores for like a minute)

How come they don't stay at 4.4ghz the whole time while playing? wouldn't that give me more FPS? or a more stable FPS anyway.

Core 1 - 2101.4
Core 2 - 1701.1
Core 3 - 1601.1
Core 4 - 3302.2

Is an example of what I'm seeing, is there anyway to force them all to 4.4ghz while playing games? or is there no point?

Because they apparently don't need to be (not enough load to push them to 4.4, which would mean that the GPU really is the bottleneck), but yes, you can use the High Performance power plan in Windows to lock in full speed. Control Panel -> Power Options and select High Performance.

Okay so there is no reason to lock them at 4.4ghz? tried using Power Options high performance, did another recording of the monitor and the cores are still all over..

Core 1 - 3000
Core 2 - 1500
Core 3 - 1601
Core 4 - 3302

etc.

Would speedstepping off fix this?

That's interesting. With High Performance, it should either be at 1.6 or 4.4 (although for me, it's always full speed, but I've seen others that still idle at 1.6). That's how I got my CPU-Z Validation.

I still have SpeedStep and all other power saving features enabled, so that shouldn't affect anything.

Are you sure that the Minimum Processor State is set to 100%? If it is, there shouldn't be any way that it's throttling down.

Go to High Performance and then go to "Change Plan Settings" -> "Change advanced power settings" and go down to "Processor Power Management" -> "Minimum Processor State". That should say 100%.

I have all C-States enabled, like I said, though, but that shouldn't have any effect on this.

To answer your question on whether or not it's even worth it to run max speed, I would say no, in this case, but now I'm intrigued as to why High Performance doesn't seem to do anything for you. That's what I'm having you check on, though.

I just figured it out. tmonitor is strange. I just set my 2500K to High Performance, which gives me a solid 4.5 in every other program I have, but tmonitor tells me it's 1.6... Very strange and very obviously not right.

Try CPU-Z. That should tell you 4.4.

Honestly, I've never heard that (with Sandy and Ivy CPU's), but I've never had any issues with it (I use offset mode, as well).

The game probably isn't multithreaded very precisely, so it will be moving the active process around to different cores, and the slave processes probably are less frequent and complete quickly or go idle.

So say you had prime95 running with 1thread. If you don't mess with any affinities and try to monitor what happens, you'll see all the cores go whacky with different speeds and report like 25% usage as the work gets passed around to all the cores. I propose that similar things are happening for you here.

Go ahead and play with it, but my guess would be all the fiddling won't change anything in practical terms. You may get a "report" that you like showing 4.4ghz but it doesn't change anything.

You may get some gains messing around with affinities. If i were you i'd search WoW forums to see what people say about multi-threading and if setting affinities can increase performance.
