M17X i7 processors, can someone list them in order of power.

I`m just wondering if someone can do us a quick favour, can you list the processors that have appeared on the M17X in ranking order, top being the most powerful down to the least powerful.

Just the R2 onwards is fine, its just their are so many variations of the i7, i need to know where certain ones rank. As an example, where would a i7 M620 rank compared to an i7 840QM etc.

i believe with the use of Throttles stop and o'cing, it goes this way:

920xm/940xm
2920xm
2820qm
2720qm
2715qe
2710qe
2635qm
2630qm
840qm
820qm
740qm
720qm
2620m
620m

 

I think the i7-2920 maybe equal or to 920/940XM overclocked with throttle stop.

 

now that is funny, unless you can overclock your 920/940XM by at least 50% then the list is more like this lol and that is running the SB cpu's stock, I seen the reviews do a google search

2920xm
2820qm
2720qm
2715qe
2710qe
2635qm
2630qm
2620qm
920xm/940xm
840qm
820qm
740qm
720qm
2620m
620m

Ok you two, no need to get into a peeing contest.

Ok, it really depends on if you are using applications that are more 1 core based, or multicore applicable. And if you overclock.

At stock speeds...
2920xm
2820qm
2720qm
940xm
920xm
840qm/2630qm (difficult to say, 840qm has higher turbo, 2630=higher base)
820qm
740qm
720qm
620m

Overclocked... This is kinda difficult depending on how much you overclock. this is a rough approximation...
2920xm
940xm/920xm>=2820qm(Once again, depending on how much you overclock)
2720qm
840qm/2630qm
820qm
740qm
720qm
620m

Since when was the 2715 or 2710 or 2635 offered in the m17x ? lol

 

well, I ran some tests using my 920xm with TS and a no factory o'c (bus speed is default), and here are some of my benches:
(Cinebenchmark 10.5 & 11 , 32&64bit), superpi, wprime, 3dmark vantage, just so you can compare with the benches at notebookcheck:

now although I am comparing an unlocked 920xm vs. stock 2920, please note that these scores were achieve without any o'cing to the bus speed, many users out there who are looking to get the best out of there cpus have even way better scores such as this:

http://img140.imageshack.us/i/fmazda.jpg/

that's why i said stock 2920 vs "sort of stock" 920xm(only TS, but no o'c) = 920xm wins
but o'c 2920xm vs. o'c 920xm, now this is what i am interested in knowing, Geoffxx can u do some benches since u have the 2920?

 

I honestly don't get what all the benchmarks prove???

I don't see a comparison of 920xm and 2920xm scores, just 920xm scores.
And using TS on a 920xm results in a non stock 920xm... hence why I divided my list into OC'ed and non OC. Comparing an OCed 920xm to a stock 2920xm is apples to oranges, both OC or both at plain stock (no modification) is the best way to put it.

 

Simple solutions....get the 920Xm to be running on the base 2.5ghz and compare with the 2920xm stock clock.

This will be a super fair comparison... if there are major differents running the same speed. means SB artitechure has an advantages, else not much diff getting a 920xm over an 2920xm unless u need the AVX ext...

 

Better than that just take a look stock vs stock
PassMark CPU Lookup

 

Can anyone help us with the o'ced vs o'ced comparions, so we can see how both cpus perform at their best?

 

Guys, while I love a good debate, lets keep the opinion pushing to a minimum. Everyone is entitled to their own opinion. Not everyone wants to use throttlestop, not everyone benchmarks... Its that simple. As speedy mentioned, many look at stock vs stock. Others simply dont care and just focus on having fun and enjoying their system.

So, moving forward, lets not turn this into a personal crusade. Thanks guys.

 

just curious about where a Qx9300 would rank

 

just don't want the wrong info provided here, the simple answer is the new SB cpu's are far superior in every way there really is no argument, also when benching the base machine makes a difference AW being amonst the fastest out there, when you have a 2620QM that can trash an old revision of cpu then there's not much more to be said, intel have done a great job

 

According to anandtech Sandy bridge mobile and their benchmarks they said 2820 SB Mobile at stock speed is equal to i7 920 DESKTOP overclocked to 3.5GHZ

I Have never seen anyone ever claim that 920xm/940xm is equal in power to desktop i7 overclocked to 3.5GHZ in the past but many people have paid +1000$ for these previous generation mobile cpu so they don't like the fact how fast is SB compered to previous generation

Not only SB is fast but it's cool, no need to overclock it to its limit and burn a hole in your laptop just to reach sb speeds.

 

the link I posted speaks for itself, it compares desktop - mobile SB and old XM cpu's. There's not much else to be said here, as to the original poster, you can't go wrong with any of the SB offerings starting with the 2620qm then 2720qm then 2820qm and the ultimate 2920xm extreme, they all perform much much better than previous cpu's from intel

 

We can settle this easily. Geoffxx has a 2920XM in his R3, and I have a 920XM in my R2.

By the way, I do realize that the 1st gen. i7 is dead tech. I am excited that the technology keeps progressing. Everyone should be.

Geoffxx, I'll post whatever I've got for benchmarks with my CPU at stock speeds, no OC of any kind. You do too. Did you buy that 2920 off of eBay? That's cool to have one of those bad boys in an R3!

 

I will be glad to bench i7 920 also to have a bigger sample.

 

Geoff since you have the 2920xm on your R3, can you post a screen shot of cpu-z with the cpu and mainboard tabs open? I would like to see some of the info on it. How are you liking the 2920xm?

 

Thanks for the detailed replies, at least it made for a debate between the techies of which i aint one lol

I take it the newer i7's are geared for sandy bridge ?

Lets say you bought an R2 machine, can you upgrade that to sandy bridge with a newer i7 processor or would it need a new motherboard as well ?

 

Yes, the 2nd generation i7's are Sandy Bridge. R2 and Sandy Bridge don't mix. That's what the R3 is for.

 

well you young guys can strut your stuff around benchmarks and what ever else, I just cruise along making claim to nothing, I don't need too lol

now if you want to step up to my xx I strut all day

enjoy your trip guys what ever it is

i almost think there is a slight doubt in my spec, - in shipping lol

 

i would also love to see some benchmark results for those ES 2920xm in the R3, and if it's done with some overclocking that's great too...

 

So you're saying that you ordered that configuration from the factory? What website? Also, you won't provide any benchmarks for the 2920? That's your decision I guess. A lot of folks would really like to see them though.

 

This reminded me of a kid getting pissed off and taking his ball and going home."Screw you guys i'm goin home" In my best cartman voice.

 

Probably hid evolution, they have a lot of extra options for a premium.
Or he could have ordered the 2920xm from ebay, there are a couple for 888.

 

I just want to see a cpu-z screenshot with the cpu and mainboard tabs. I don't think Dell offers the 2920xm, so Im assuming is an es or bought elsewhere. Where did you get it will? I may pick one up too

 

He ordered it from HIDevolution just like me(we're both pissed at the prices here too ) but I got the lesser one since I'm never going to ever use it to it's full capacity.


Also not going to take a risk just in case any problems happen in delivery.


I'm happy with the one I got it's best buy if you have a budget in mind.

 

You`re not really expecting 920XM to win against 2920XM at stock speed are you?

 

No. If that was the case, the 2nd generation i7 would be nothing but a joke. It appears that the 920XM at stock speed it right underneath the 26XX. If you read further back you'll see that someone placed the 920XM at the very bottom of a long list of CPUs. I should have known better than to post anything in a pissing contest thread like this one.

 

ES ???? who mentioned the ES word, how about production release from Intel........you know - from the big cpu shop, you're posts are getting muddy lol or should I say back to muddy like your first post on this thread

 

This. this exactly +1 rep

10char..

 

sorry for the confusion...I am talking to other members with R3, ES or not...

 

Non-ES 2920XM are quite difficult to locate at the moment. If I were receiving a notebook with one in it, the first thing I would do after making sure it starts is tear the system down and check.

But that's me.

Grats on your r3. Here's hoping ThrottleStop will get some functionality with gen2 XM.

 

did nobody read the review on that link I posted, and may I also add that in an AW the gap would be greater, some cleaver guy called Tom sat down with a desktop cpu a 2920XM extreeeme and a legacy old out of date 940xm and did some very extensive benches, the latter forgot to run when the the flag was dropped




quote......

The formerly-high-end Core i7-940XM is beginning to look like a budget part

while the new mobile CPU trumps the old one by a far more significant 41%

The desktop Core i7-980X beats the mobile i7-2920XM by nearly 40% in Photoshop, while the -2920XM outpaces the -940XM by a similar amount

Is it time to recycle last-year’s high-end notebooks? The Core i7-2920XM quad-core continues its strong showing, placing marginally behind the six-core i7-980X.

The desktop Core i7-980X stands nearly 50% higher in Sandra Arithmetic compared to the mobile Core i7-2920XM, thanks to its greater number of cores. Proving the advancement in mobile CPU technology, Core i7-2920XM beats its flagship mobile predecessor by a similar amount.

Likewise, Sandra Multimedia shows that the Core i7-980X’s 50% greater number of cores gives it an approximate 50% performance lead. In spite of that loss, the old mobile CPU looks like a chump compared to the Core i7-2920XM.

do we need to say any more lol

 

I rarely oc, no need for it, I like my equipment to last, but I am content in knowing that if I did oc nothing in the mobile world would touch it

 

I respect that Geoffxx but having a 2920XM without overclocking is like driving a car with 12 cylinders but have disconnected 2 of them

Isn`t the 2920/920/940 intended to OC and that they take no damage of it (within reasonable levels)?

 

I'll let you know lol

just going to cook breakfast on my 2920XM fryer lol

 

Now your talking! Lol j/k. I'm sure it's going to be a sick cpu. Hope you enjoy it. I know s/b is a leap ahead of it's predecessors.

 

so you really want nothing in the mobile world to touch ya?

looking forward to your results

 

Geoff, please also remember that none of the reviews you keep quoting had the 920/940XM using ThrottleStop. Boosting the TDP/TDC, even with no overclock at all, nets me a ~25% performance gain. ThrottleStop starts when Windows starts, and runs seamlessly. It's not something that I fire up when I want to do some benchmarking. At any given time I can pull a CPU score of 21-22K in Vantage. The highest temperature I can achieve is with stress testing programs such as OCCT or Prime95, and that's 89°C. The rest of the time it hits the mid 70s. No, the 1st generation i7s are not that impressive in comparison without ThrottleStop.

 

also remember that the benches you are quoting do not reflect the full performance spectrum of a cpu in a system doing what cpu's do, also note that the preformance increases in some of those tests where between 40 and 50%, it was simply wrong of the poster of that list to place the 9##XM chips at the top regardless of OC, but never mind I think most people get the idea and no point in dwelling on it

 

I am just thinking out loud but for quick test and short benchmarks the 2920xm is very powerful. Under heavy load the sandy bridge chips reduce the multiplier after like 30 seconds and throttle back. The throttling is what is hurting the chip in comparison to the 920xm. The older XM chips can run at full power all day long when running a single test. Take for example Wprime which would be like a encoding job that last like couple hours. In the 920xm the chip would run at full multiplier and full load at all times. The sandy bridge chip will run full load for 30 seconds and then it gets scaled back down. The performance leap and temperature controls of the sandy bridge is wonderful and truly what you expect when you see a new revision. I love my sandy bridge 2600k and my 920xm but both of them have their Pro's and Con's.

 

What do you mean by that the SB CPUs throttle "back"? Like said a million times, it will still be running with turbo at much higher speeds than the base clock. You have a certain TDP which CPUs can go on forever in. Sandy Bridge have additionally a peak that is higher than TDP where it can reach speeds beyond TDP. Example the 2820QM. The base speed is 2.3 GHz, speeds within TDP is up to 2.7 GHz in Quad Core mode, while 2.7 GHz to 3.4 GHz is above TDP. The time it can hold these speeds are determined by the thermal envelope of the laptop and a timer. With good cooling you can see the threshold within TDP could be higher than 2.7 GHz.

Anyway, i am not going to argue about SB vs old i7 anymore. Its getting old and frankly, both the 920/940XM and the 2920XM are all very good CPUs.

 

So how far is sandy bridge a leap forward comapred to the R2 machines and their processors, is it huge or minimal in performance ?

Would a basic sandy bridge i7 processor be more powerful and quicker than a high end R2 i7 processor ?

 

Even 2630 is much faster than 940xm at stock speed unless you plan to overclock like crazy previous i7 is obsolete power wise compared to the newer and cheaper i7, plus 940 runs hot and leave you almost with no battery life unplugged

 

You really can't discuss 920xm/940xm vs. SB without throttlestop. The weak argument at hand is, "stock for stock," as if Throttlestop (and the true potential of 920xm/940xm's) doesn't exist. As noted of course stock for stock, SB is going to put the smackdown on the older generation. That isn't even a point of contention.

The question still comes down to Throttlestop and the 2920xm and what, if any, limits Dell (or any other makers) have applied to BIOS since it has BIOS level hard locks that will prevent even Throttlestop from overclocking it. I'm hoping Throttlestop whips the 2920xm into shape the same way it did the 920xm/940xm. The only thing I do not like is with a simple BIOS update, programs like Throttlestop could be locked out with the 2920xm.

Still waiting to see someone with a 2920xm use Throttlestop and see what it can produce because as of now, with Throttlestop, 920xm's are hitting 3.2ghz+ (940xm 3.33ghz+) across all 4 cores rock solid hours on end which is why it is still top dog for full core tasks. With Throttlestop and sub 8 second scores, they are matching and exceeding the 2920xm's Wprime 32m score (which plays to the 2920's short term boost benefits even) of ~8.5 seconds. As a result, the 920xm/940xm with Throttlestop are then obviously doing even better than the 2820qm and 2720qm.

As previously noted, Throttlestop is easy to use and can be set to auto load (or you click one button).
