Save the money and get a good GPU and you will be happier. But of course, it only matters if you are gaming at 1080p or higher.
Agreed. Hell, CPU only matters for AI-heavy or badly optimized games, or if you play in 1024x768 resolutions.

It would be useful to have more CPU-demanding games thrown in like GTA4 and SC2 where the true potential of the chips would appear.

One more testing that you might want to do, is the 2600k with max OC (4.6 GHz+) and HT off, to simulate a 2500k on it's best, which is the best bang for buck CPU. Bet results would be similar, but would prove that you do not need a bleeding-edge CPU for the latest games, better save that money towards an SSD and a GPU upgrade.

Nice review, ekg84.

In your tests, I notice the i3-550 ram is clocked faster than the i7-2600k ram.

In this review here,
http://www.xbitlabs.com/articles/cpu/display/pentium-g850-g840-g620_4.html#sect0
stock i3-530 with 1333 ram and stock i3-2100 with 1600 ram
better performance with the i3-2100. I guess faster ram helps.

Question: In your tests, in the bios, what is the QPI speed of your i3-550 @ 4.33GHz? I'm curious because I know that overclocking QPI (DMI) can improve ram performance (latency and bandwidth).

I recorded this Hard Reset gameplay vid @540p 30fps with my i3-530 @4.15GHz. Could not record at 720p or 1080p. fps was too low (under 30).
I think my single 7200 rpm HDD is too slow.
Another question for ekg84,
Have you tried recording gameplay with your i3-550 and your SSD? Can you record 720p or 1080p gameplay at 30fps or higher?

This is garbage. Unless you're trying to tell me the A8 is faster than the 2500K this is just a bad test.

I still don't see why the maximum FPS for the i3 is higher than the SB unless it's testing methodology or some setting.

After reading your sig rig (title) I can't imagine where you are getting that idea from... rolleyes.gif

If you are questioning the results, go to TechSpot and email the editor. There are quite simple and obvious reasons but you clearly don't see them because all you see is "AMD CPU FASTER THAN INTEL?! NO WAY! IMPOSSIBLE! FAKE!".

No, it's because the i3-550 that ekg84 tested was overclocked.

With non-K SB processors getting 5-7% in OC improvement is actually a feat, because the multiplier is locked, and BCLK OCing is harder since now you've linked the BCLK to PCIe speed (and other stuff), and if you pass a certain threshold the whole system gets unstable, that's why you see only SB OC's with multiplier only, and that's the real value of a K processor. Even non-K i5's and i7's can be OC'd a bit more nicely, but that's done using the Turbo Boost multipliers (fooling the mobo in using the turbo multipliers on all cores) but sadly, the i3's lack turbo features.

A "measly" i3-530 can be easily OC'd to 4 GHz without generating much heat or needing extreme voltages and using the *cough*fail*cough* stock cooler, and that's almost a 36% performance increase over stock clocks... and most can go over that that easily (a 4.2 GHz OC is around 43% increase) with more specialized cooling. I bought my H70 for $65 used, and my chip could easily hit 4.5-4.6 GHz but i chickened out with temps as i did not want anything above 70c, plus my ambient temps are never below 25c on the day, and can go as high as 34-36c... hell, the budget Hyper 212+ would do a fine job of keeping the chip cool with a 4.1-4.2 GHz OC with a $30 price tag. Add into that an i3-2100 provides roughly 5-20% performance increase over a stock last-gen CPU, any lightly OC'd Clarky can beat it.

Too bad there are no i3 K-series.

Good question. Would be useful to see a CPU-Z shot of the i3. Maybe i could lover my QPI and also lower VTT volts, tho i love to see two 4 GHz speeds on my CPU-Z screen smile.gif

It's not like you'll see a lot of max FPS's unless you like too stare at the game's walls or stay still (like a camper) all the time. Min and Avg are the ones that matter the most.

Is the i3 forcefully clocked at 4.3 while the 2600 is using Turbo and constricting to a single core?

These results are unnerving.

I may not be a genius, but I think this is because of the higher clock speed probably. But that is just the highest fps. Doesnt mean it stays there for long time, cuz in all the test i7 wins in the averages.

These aren't all OC'ed to the same speed. Also, what's the test system used for each CPU? Where's this bench coming from?

Also, keep in mind this is the Beta for BF3. Once it full releases I expect to see a different picture.

*SNIP*

You cant really say they are faster, this graph is basically proving that the GPU is more important than the CPU for BF3, since even with a GTX 580 the CPU is not bottle-necking the system. All the FPS's are basically the same, only 1-5 FPS different. So, it's just showing that even with a mid range processor, your gaming performance will still be as good as your GPU and your CPU will not be bottle-necking your system.
