    just a thought, "is there anything better than 940xm for a m17x r2? " i am getting a m17x r2 with a 720qm and i dont know what i should do, just keep this cpu for now, wait for prices to lower, or upgrade to something better now.

    i think for now the 720qm will be fine for me, but i just heard there is a new "planetside" coming out called "planet side next" i was a beta tester in that game in 2003 and thats the best game iv played so far, its a huge MMO that needs a good PC, and now that i got money for a good computer i want to be ready with good specs for when it comes out, early this year beta testing will start they say.

    anways, do you think intel will be making anything better then the 940xm or do you think they are going to change the whole thing, i dont no what its called sorry. like if something new comes out thats better then the 940xm, will it be compatible with our m17x r2?

    From what I understand the 940xm is the best proccessor available for the R2. There are allready proccessors out that are better than the 940xm but the sockets are diffrent and are not compatible with the r2.

    Intel has already released their next gen mobile i7, so no the 940xm is as good as it will get, though the 940xm is crazy good. It's unlocked, so with the use of Throttlestop, you can overclock it considerably. You wouldn't be able to do that with the 720qm. The 940xm will be better than all but the very best new i7.

    thanks for your responses guys, yeah thats what i meant i just didnt know how to say it, the sockets are different so newer ones wouldnt fit.

    i was thinking about getting the new m17 r3 because i can get the i7 2820QM with it, but from what i read it has less performance then the r2's but with all the specs i dont understand how it is.. because the i7 2820QM is so much better then the others, isnt the i7 2820QM alot better then the 940xm? i heard it can be OC really good and far with it being stable, and the new r3 can hold 32gb of ram, i guess if it has to do with the video card why cant i just upgrade the video card myself? then wouldnt it be better then all r2's in every aspect?

    look at this thread i just made where i talked about it

    dont get the 2820. 2720 and even the 2630 have better performance at stock than the 940XM. Get the 2720 or the 2920XM. the rest make no sense to me.

    really? the lower one is better, im just going by what is on dells website, its even cheaper. why is it better?

    the 2630 is faster than the 940XM at stock speeds. but its not better than the 2720 or the 2820. im just saying its not worth the upgrade cost to get the 2820.

    the 2920XM have some value because it might be overclockable. but we wont know for sure until it is tested

    from what people are telling me its better to have a 920xm or a 940xm then the new 2nd gen i7 that come in the new r3's is that correct?

    there are only three processors you can choose from on dells site and that is

    Intel® Core™ i7 2630QM 2.0GHz (2.8GHz Turbo Mode, 6MB Cache) [Included in Price]
    Intel® Core™ i7 2720QM 2.2GHz (3.3GHz Turbo Mode, 6MB Cache) [Add $150.00 or $5.00/month1]

    As of right now a 920xm or 940xm will be able to overclock higher and be stable. The sandy bridge if looking at stock then the lower end sandy bridge will be a stronger chip. No one buys a 920xm which has unlocked multipliers to run it at stock. Any person with half a mind would use the Throttlestop software to really tap into the powers of the 920xm/940xm. In that software you can control the multipliers and you can adjust power tdp/tdc. To have a successful overclock that is stable and usable you need to increase the multiplier but also increase power/juice to the chip to make it hold the clock speed and be stable under load. I am not 100% sure but i believe the sandy bridge mobile chips you can't adjust TDP/TDC. In the sandy bridge desktop "K" series you have access to all functions. Also in the desktop world the BCLK is not recommend to be changed from stock 100 mhz since it is not yet know if it is safe for the chip and even when it is it can be adjust very few points. In the r2 you can adjust the Bus speed from 133 mhz up to 155mhz stable and some have gone up to 166mhz. When you increase bus speed and increase multipliers you are able to hit high overclock and with unlocked TDP/TDC you can make the overclock stable. So if you get a 920xm or 940xm and use it stock then use sandy bridge is probably more powerful and you should give that chip to somone who will actually use the chip. If you use Throttlestop along with you XM chip no fears your laptop is a BEAST and you will trump many chips out there.

    enjoy

    Also remember that the 920XM and 940XM are the same chip. You can buy the 920XM and get the same performance and save a couple of hundred dollars.

    The other thing to keep in mind is the fact that Dell has yet to issue a 2920XM for the R3. With out BIOS support, the chip does no good. But everything Faiz stated is 100% on the money. But wth the new Sandy Bridge, until somone gets a system, it's mostly speculation. If the SB Chips are infact TDP locked, a 920XM/940Xm will wal all over them because the chips are highly capable. When I was benchmarking, I was running all cores/threads at 3.8GHz or somewhere there abouts. Allowing the TDP to be increased gives the CPU more power to hold a higher multiplier in turbo boost mode. So if you increase your multiplier to 27x, and run it at stock TDP, when you run wPrime 8 threads and give the chip 100% load, your actually only going to hit 17-18 multipliers. Increasing TDP to crazy amounts (like I've done) will allow that chip, under the same conditions to run at 27x multipliers. It's highly flexible, and my only gripe is that I don't get to control voltage :D

    EDIT: Just be careful with throttle stop, I basically ruined a 920XM :p That chip now won't overclock very high, but runs fine at stock speeds. I may have to test it again sometime. But my 940XM doesn't hold a load quite as well as my 920XM. Wow I spent too much money, 1 920XM OEM, 1 920XM ES, 1 940XM ES... :rolleyes:

    I just thought I would add that there is no discernable performance gain in games though using a 940xm vs a 740qm. I saw benchmarks on a german site comparing the processors and in all of the latest games the slower i7 performed the same (sorry i don't have a link).

    Sure in benchmarking video encoding and cpu intensive programs the 940 will murder the 740 but for gaming the 740 is fine.

    As an example my buddy has a desktop i7 950 and no game has come close to maxxing out the processor. I have yet to test this on my new M17x R2 740 but I think once you get a decent i7 most modern games will be limited by the graphics card more than anything.

    I'm happy to be corrected if anyone has done a comprehensive test, I was thinking about getting a 920 ES and after comparing the gaming scores it wasn't worth it. I only use my m17x for gaming :eek:

    Oh yea, if there was anything better than the 940XM, you would se it in my sig ;) lol Although at the moment I have a 920XM ES installed.

    You are gonna have to wait for joker to post but in quad core games 920xm makes a big impact. If i am not mistaken 720qm runs at 1.6-1.7ghz when loaded all cores down. The 920xm on the other hand can do 26x on all 4 cores that is 3.5ghz. Now in games like BFBC2 or GTA IV having that extra raw power will gain you like 5 fps (don't quote me on it) but more importantly it will keep your FPS stable and stop it from having dips. Also my current 920xm i can run core's in this order from 1-4....28,27,27,26 so my slowest core is running at 3.5ghz and my core 0/1 is running at 3.75ghz. Now add some FSB overclock and slowest core is at 3.9 and core 0/1 is at 4.2ghz @ 151 fsb. 920xm when using the Throttle stop will annihilate desktop and laptop chips and you will see that effect in daily use, gaming, encoding and heavy cpu intensive tasks or horribly optimized console ports.

    I guess I was basing my opinion on a translated german website so I'll defer to the experts.

    wait what no way.. its the same exact chip? then why it is 920 and one 940xm? i would think the other gives better performance, i mean your right its even more money. i dont understand.

    They are essentially the same but the 940 oc slightly better.

    ok so if i really had to decide then go with the 940xm since it clocks better.. that doesnt sound resonable? or is the slightly better oc not noticable?

    i just dont understand why its the same chip if its different version and one is suppose to be better then the other its even more money for the 940xm

    See this

    http://forum.notebookreview.com/7067284-post68.html

    Basically the 940xm is $200-$400 higher and will probably Overclock one multiplier higher than 920xm. Is that a guarantee no but between the 2 money aside the 940xm will be the stronger chip. Many 920xm chips easily keep up with 940xm and the slight slight difference in clock speed between the 2 chips is not worth a 50% premium in price for 5-10% increase in performance if that. Get which ever chip you can afford and both will blow you mind :D

    940XM only has one more multiplier at default settings. Everything else is the same. Same stepping, same voltage, ect. Both unlocked multiplier and TDP/TDP. Heck look at the benchmark thread. 920XM is on top. Not much differance in the benchmarks once overclocked.

    man the 920xm doesnt sound that much of a difference, im not the kind of guy that just wants to spend more money for no reason, i guess the 920xm it is, i really wish the 940xm performed better because isnt this the best CPU that will ever be in these m17x R2's " the 920/940xm's "

    Yes i'm affraid that will be it/nothing on top of those for the R2.
