Difference between ES 2720qm?

High Performance could make the difference, if it isn't your CPU could be parking cores or something. Also have you done any registry tweeks for an SSD or something? Those can reduce CPU performance.

According to passmark the average is 7196

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-2720QM+%40+2.20GHz

You should try some other benchmarks, this one could be an anomoly. What is your CPU score on 3dMarkVantage?

 

But isn't the turbo function activated when 1-2 cores is in use?
I will try with 3dMarkVantage after work.

No tweaks to SSD.

 

Correct. Check your power profile settings, lets be sure it isn't that also.

 

I am thinking about possibly upgrading my Thinkpad T420's CPU with one of these, since they are half the price of a retail chip. Are ES chips safe to use?

 

They are absolute safe to use

 

3dmark 2011:

Processor clock
2993 MHz

Score:
P2009 3DMarks

Your result has the following problem(s) and will not be shown for example on leaderboards:: Graphics driver is not approved. (What is this?)

 

Hey just ran passmark with my Q154 and got 8055 with my hyper-X ram and windows set to high performance.

 

i cannot stress enough the importance of having throttlestop when running benchmarking tools. Throttlestop cuts off windows and forces its own power control. just set the multi to turbo and all modulations to 100%, turn it on, and it will give the best possible performance. Windows power management for the CPU is BS in my opinion.

 

And I only get 6995. Sick...

 

My test

 

Ran it again to take a SS, got a slightly lower result:



I get 7282 on battery in balanced.

 

I recently retrieved my BTO 15CL37 ( Clevo P150HM ) , But i'm experiencing allot of troubles random crashes, etc bsods.
After benchmarking my hardware it seems that both my CPU & GPU are not performing to an equal lvl as similar systems. Below is info about my CPU

 

Hmmm, looks like there is a lot of variation in ES performance. This makes me think they are a risky investment in that performance is not guaranteed. I returned my ES CPU. I was able to buy a new M17 for a great deal and decided getting the 2720 from Dell was better so could get a 4 year complete care warranty. Also the 6970m GPU on my original M17 died suddenly, this made me value my warranty more than I had original thought I would.

 

I also tried ThrottleStop 3.20 but it does not apply any chances, though they are not grayed out. Anyone can provide info about this?

 

Is it turned on?

Also why are your TM1 and TM2 dissabled?

 

Uh oh, his ES may not have temp sensors AT ALL. My ES core 2 quad didn't have them

 

Yes throttlestop was turned on and I also tried the 3.00 version to be sure.
Regarding the TM1/TM2 , HWINFO64 says it's Supported but disbled. Although I cannot edit it in my bios or so.

 

OK, regardless of the temp sensors, isn't it pretty obvious you got a bad chip and should return it?

 

I think so, but I think I need more evidence of the cpu malfunctioning , I'm running benchmarks now any tips?

 

Make sure it gets through the intel burn test.

 

Prime 95 @30min no crash/error;
IntelBurnInTest @ standard No crash/error;

IntelBurnInTest @ maximum No crash/error;

IntelBurnInTest @ Standard + Furmark running = Stable. Except when the programs stop and the load drops and it's starts downthrottling I'll get a light blue screen ( Not a BSOD) and have to hard reset.

Burn in + Furmark :

 

I got my Core i7 2720QM ES 8MB Q154. No problem at all except it is performing like a core i7 2630qm...It performs nice on one core super pi = 11s so no problem here but i get i7 2630qm scores on 8 cores ;-)

No throttle issues since temps are low and the cpu is always in turbo mode under load.

Either i'm not lucky on the sample or my vostro rig is not that good.

Anyway it's a big performance boost from a core i3 2310M


Can you guys run this x264 bench, please ?

Yours is performing noticeably better, 15% more in the first pass...that's a huge gap for the same ES but that's what i was expecting. I made benchmarks and my perfs are between core i7 2730qm and the core i7 2720qm on 8 threads. But on one or two threads it is working fine i have same perfs than the core i7 2720qm.

At least i'm performing better than this guy with his core i7 2630qm:
x264 HD Benchmark 4.0 - Page 4 - Tech ARP Forums

One good point is that i will not experience throttling like him even after hours of stress since my temps are really fine.

Overall i'm happy with the purchase it's far enough powerful for my needs but i'm a little disappointed when i see your results.

Another interesting thing is that this cpu is colder while idling than the core i3 2310M i had. The fan is off 99% of the time while surfing on the web now. It wasn't the case before.

 

One question meaker what are the frequencies of your 2720qm while your are stressing it on 8 threads ?

Mine starts at 2,6ghz for several seconds and then stabilizes at 2,5ghz for the rest of the time.

If you could do some Hyper pi benchies on 1,2 and 4 threads that would be great, it's a fast bench and you can easily choose the number of threads :
http://www.xtremesystems.org/forums/showthread.php?176904-Hyper-PI-0.99b

I'd like to know if my loss in perf is only on 8 threads by curiosity.

AOGenMark.exe -t 1 -s 8 ??

 

Thanks for you results.

You have to use the .bat files included in the archive to lauch the benchies.

But you can use Hyper Pi if you want it's faster.

Here's what i get with Hyper PI 1M :
1T : 11s575
2T : 15,975s
4T : 17,253s

 

Starts on 2,60ghz and stabilizes on 2,20ghz after 6 second or so..

 

Seems your cpu is even worst than mine. Buying an ES cpu looks like a lottery...But QS samples are far more expensive.

I bet meaker has a higher turbo on 8 threads. That would explain everything.

 

Hehe, yeah. But it is cheap compared to a new cpu I will buy i7 extreme next year.

 

Yes when running that test it goes at 3ghz.

1T = 3.3ghz
2T = 3.2ghz
4-8T = 3.0ghz

 

Damn that's one of a turbo. Surrealist. Even OEM cpus don't have such a turbo. Lucky you. The seller must be in love with you to sell you this one ;-)

 

Really? I thought once all the real cores were reached turbo stayed the same for any more threads.

What's it supposed to be?

 

Don't know if my lap could handle a core i7 extreme cause of the 55W tdp but something like the core i7 2860qm with a 45W TDP should be fine. And maybe there will be even better in a few months. Don't know if upcoming 22nm cpus will be compatible with our laps though.

 

I don't really know but i'm pretty sure there are not supposed to stay at 3ghz when fully 4-8 threads loaded more than several seconds in order to stay within the 45 TDP.

I have this :
1T = 3.3ghz
2T = 3.2ghz
4-8T = 2,5ghz

Your cpu can stay at 3ghz fully 4-8T loaded for hours ?

 

If you smack it with something like linX then it will oscillate between 2.5-2.8ghz (starting a 3ghz), if you are running a normal load like a game it will happily sit at 3ghz all day long.

 

Mine sits at 2,5 ghz all day long. Games or Linx don't change anything. The hottest core remains under 75 degrees celcius so it's fine. It would probably burn at 3 ghz ;-)

Under some benchies i hit almost 80W on my wattmeter and my power adapter is rated at 90W. So i don't think it could handle a more power hungry cpu.

 

Ah but I have a dual heatpipe dedicated cooler designed to take up to a 2920XM

 

That's all ? i'm not impressed ;-)
there will be more powerfull 45W cpus than this crappy 55W 2920XM soon ;-)
Anyway i never buy high end cpus that's a rule.

 

55W is 55W, regardless of the speed of those CPUs, it will handle any 45W CPU at any speed.

 

How can I change the multiplier? Program for Windows?

 

try intel XTU or throttlestop

 

I don't believe the 2720 ES are unlocked.

 

This is normal for a 2720.

I had a 2630qm that sat at 2.4ghz all day long 8 threads going 100%

 

really? My 2630qm goes 2.78 ghz across all 4 cores under load.

 

yes it does at first...but as your "short interval time" runs out, you'll drop to 2.6ghz, then eventually to 2.3-2.4ghz

I'm running the unlocked A08 bios so at first my 2630qm would hit over 2.9ghz...but then as time went on, it would drop slowly...eventually settling at 2.45ghz

run prime95 or some other CPU stress tool and monitor your MHZ in something like HWINFO64

My current CPU (2820) will turbo at first at 3.4ghz, but it settles at 2.8ghz with all 8 threads @ 100% utilization

 

SlickDude80 did you try using intel XTU version 3, you may be able to get your cpu to stay at 3.4ghz.

 

i've played with XTU and it works fabulously...however, i don't use it for everyday. I only use it while benching. What i have found is that if i set the max turbo tdp to 58w, i get max advertised turbo speeds forever. No slowdowns after the short interval.

So my 2820 stays at 3.2ghz forever (after a slight 5% increase to the bclk). I haven't tried upping the tdp any higher but i haven't had a need to.

 

Wow i will try this when i get back home. That sounds amazing for benching!
