processors: 2760 qm vs 2860 qm..which one to get? What does having + 2 MB cache mean?

Hey guys,

I know that the 2760 is very close to the 2860 in terms of performance and according to passmark.com, it is MUCH better value.

However, what does having +2 MB of cache really mean? (2760 has 6mb while the 2860 has 8mb).

Also which processor would you guys get (or have gotten) and why?

Sincerely,
Nappy

 

intel 2760 is really fine. Though it is 2.4ghz, in reality it gives you 2.6ghzish if it stays cool for all 4cores in 100% load.

2mb cache will not make any visible difference. Seems like 2760qm does the job. For me at least.

 

BTW dellalienware,

How does your quadro card in your dell workstation compare to a 6990 radeon in terms of gaming?

Dear dellalienware,

Also, what's the purpose of having 32 GB of ram in the workstation laptop? I'm curious because i do CAD work/Rendering as well..does it help that much? Or would 8 gb ram suffice?

 

Hello and welcome to NBR, nappy123.

Please take a moment to review the forum rules.

6990 radeon will kill the 4000m in GAMING.

The 5010M will be slightly slower than the 580M due to slower clock but same chip. Hence 5010M will be slightly slower than the 6990.

And 5010M is faster than 4000M. Not MUCH, but quite a bit.

I did not run benchies yet so I cant comment on that. But 4000M should play all the latest titles in 1080p high/max settings.

 

thanks dellalienware and
noted katalin!

thanks

 

Depending on what programs you use 8gb is enough FOR NOW. If you have to run multiple softwares for rendering, editing, and storing and others at the same time, having more than 8gb can really benefit. For me, I wanted more ram so it can cache pretty much all the software I use. I do not shutdown the machine. Right now it seems that all the programs I use utilize only up to 16gb, but does use caching up to like 26gbish.

Also, I do not use SSD at the moment because I need raw capacity for softwares & Programs (need at least 700gb...) and data. Even two 512gb SSD in raid 0 are insufficient.. And therefore, since HDD are slow in opening programs, I really benefit from cachin in the ram.

 

2860QM wins

 

By the slightest of margins so is very marginal.

 

oh well was cheaper so why not..

 

Lol... the margin is extremely small.
Unless one is running CPU intensive programs, the differences won't be noticed... and even if you do, the said difference will be miniscule at best.

Get whichever is cheaper.

 

I suggest ,get the 2860 if money is not tight. saving you from upgrade.

2760 , you may get upgrade itch in a 1-2 years time. with win 8 coming this year.

 

aaaaaaaa Laptopmonkey
YOU ARE HERE ???

That is awesome Just received your CPU 2860QM and I have successfully replaced it ..
here are sreens
One thing - why cpu-z shows me that I have 2920XM ??
And HWinfo shows correctly BIOS too

 

GalaxySII, can you overclock with intel XTU V3.0?
Would be interested to know if that ES 2860QM has an unlocked multi.

 

U mean with throttle STOP ?
Uuh am scared ..
I was overclocking GPU and system was crashing so I left it

 

No, XTU is not throttlestop, it's made by intel.
Just go to the intel download page and search for XTU.

But you dont have to, I was just curious.

I wonder when laptopmonkey will get the ES IB CPUs.

 

Oh crap sorry I didn't read that intel XTU just seen overclock and answered straight
OK am on it

 

Wow looks awesome never heard about this softwre from intel !
So what should I do ? Hit Tune ?

 

Yes, check out the manual tuning tab, you may be lucky and find that you can have control over your multiplier.

 

Naaah looks like not working .. doesn't matter

 

Does this mean that I can overclock in throttle stop ?
cos when I had 2820QM this soft popped window ; CPU not supported

 

you have to enble the overriding of turbo settings and enable overclocking in the bios. If you don't have these options, then XTU will not work for you.

XTU works great for me. I can bump my bclk by about 5% and i can set my tdp to a high level to enable max turbo settings forever (no degradation after the short interval)

You can't overclock the 2860 because your mutliplier is locked. The best you can do is remove the short interval throttle to get advertised turbo speeds

 

Where do you see that locked mutliplier ? where it says ?

 

only the extreme XM processors have unlocked multi's. So if you don't have a 2920xm or 2960xm, you have a locked multiplier

 

But I have ES version and somebody said that they can left it unlocked too even in QMs

 

The myth is that there is a 2720qm es version with 8mb cache and unlocked multiplier. But oher than that there is no concrete evidence of its existance.

 

Having an ES CPU does not mean the multipler is unlocked. Only a few ES CPUs have had their multipliers unlocked. For example, the i7 2720 ES q154 with 8 meg cache was multiplier unlocked...this chip was really a 2920xm q154 in disguise

i do not believe that your 2860 ES is multiplier unlocked. But you can try and overclock it via upping the multiplier just to be sure

 

Guys sandra showed me these tips
what u think about them ?

 

This thread is a bit old, but I have a question regarding it.

Some of you mention a marginal difference in real-world (and even bench-marking results) between the chips and their cache/processing speed.

My question is, though it may be unlikely, where WOULD you notice a difference, no matter how slight? And I do not mean in benchmarks.

 

There is virtually NO difference between 6m cache vs 8 meg cache

For proof, go to these charts here:

You can compare the 2500k (6m cache) to the 2600k (8m cache). What they did was clock everything to 3ghz and run apps using only a single core so they can do direct comparisons. What you see is vitually no difference between the the 2500k and 2600k...usually within 1%

Benchmarks X86 Core Performance Comparison


and as far as speed goes...there is a 100mhz difference. That isn't going to do anything significant
