i7 performance compared to previous quad cores

[Hefemeister]

above 220 bclk is tough on most boards.

Well from our superpi thread comparing clock for clock at 4.1ghz

q6600: 12.45
i7: 9.72

q9300 @ 4ghz: 10.94
http://www.techist.com/forums/f10/tech-forums-official-superpi-1m-top-list-169586/

4.1 was about the top end for the q6600 while we have i7's running at 4.6

21,131 | Dainius | Q6600 @ 3.904GHz | GTX280 SLI @ 715/1500 | XP Pro 32-bit |ORB
20,951 | AP4LIFETN | Core i7 920 @ 4.0GHz | GTX 280 @ 697/1518/2500 | Server 08 64bit | ORB

but keep in mind the q6600 had 2 cards while the i7 just had one.

thanks for the info, I don't know much about the superpi program/test/benchmark but the 3dmark is kind of surprising. Would you say my friends score of a 16,100 in 3dmark06 with a i7 920 stock with a gtx 260 core 216 at stock is low? There doesn't seem to be any equivalent comparisons.

 

[Hefemeister]

That score seems pretty fair.

Thats about right. CPU clock makes a HUGE difference in both 06 and vantage. As far as air vs water goes, i had my q6600 at 3.6 on air, but could do 4.0 on water but it took a LOT of voltage. 1.6v to be exact. I'm running my i7 at 4.2ghz (turbo on, hyperthreading off) at only 1.4v (havent really tweaked yet).

Also, 37k 3dmark vantage Long weekend, i think i'm gonna turn off all but 1 core and go for the superPI score

I can run my i7 920 at 4.3Ghz 24/7 but my temps get a little higher than I like. Here is my Bios Template for 4.3Ghz.

I normally run mine at 4.2Ghz using the same setting as above but I drop the CPU Host Frequency to 201 and I lower the CPU VCore to 1.3v and the CPU VTT to +150

If your running SLI I recommend you copy my IOH VCore, IOH/ICH/ I/O and ICH VCore Voltage settings. I can run SLI with stability at lower settings but these voltages gave me a couple hundred extra points in the benchies

My last piece of EVGA X58 advise deals with the pci-e bus speed and overclocking. As you change your Host Frequency your pci-e bus is automatically adjusted to stay as close to 100 as possible. You can see your pci-e bus speed in the Overclocking Tab of the EVGA E-LEET Utility. My system runs better when the pci-e bus is at 100 or 101 but it often sets itself to 99. So if your trying to go higher but your pci-e clock is at 99 try bumping it up a notch or two.

whats these new features with the core i7? I know what hyper threading is but is it enabled by default? Also what the heck is turbo mode and what does it do? Is it also enabled by default?

 

[veg1992]

Turbo mode no, but it allows the i7 to have a little faster speed via a Mini-OC.

HT is enabled by default though

 

[veedubfreak]

Turbo switches all 4(8) cores from a multi of 20 to 21 and core 0 to 22 assuming it is within temp specs.

I'm happy with my current setup, will go for i7 only after the first major cpu/mobo price cut (that's what I always do). Until then, I'll upgrade the case and buy an LC kit from Petra's to practice with the LC and be prepared for OCing the i7 when I eventually do buy one.

hmm I was just wondering what kind of 3dmark06 score you have for a q6600 at 3 ghz with an overclocked 8800 gt?
