When it comes to graphics cards, you should look at the memory bandwidth and amount of gpu cores or processors. The naming game gets confusing sometimes for the two brands, but I believe for ati you just divide the number of cores by 4 to compare them to nvidias. The clocks don't really matter that much, because for example a 4650 and a 4670 are so close that you could probably run a 4650 at 4670 speeds. A 4550 though has several less cores compared to a 4650 so even if they ran at the same clocks it would be slower. You might also want to compare die size.

A 3870 compared to a 8800m gts or gtx, the performance is very close, but the 3870 does it running a little cooler and drawing less power. The reason being is its using a 50nm die compared to the 65nm die on the nvidia cards.

fyi this is a comparison of laptop gpu's.

 

Spot on! My favorite source for those details is Notebookcheck. It's about the most comprehensive list I've seen so far (helped me when I was looking at buying the lappy I have now).

 

Always take NBC with a pinch of salt though, theres often a lot of errors, or outdated information. (for example 4870s, the ones in the M17x AW are pretty much considered to be superior all round, even if only slightly,to SLI 280m at stock, which isnt reflected on NBC)

 

wow thx but why divide cores by 4 and compare them to nvidias? 4 ati cores is the same with 1 nvidia core?

 

They work in different ways so yes, roughly. Another one I heard was divide it [ATI shaders] by 5 then add 30% to get rough NV equivalent IIRC

Shaders number, Core clock speed, Memory Speed, Memory Bandwidth, Shader Clocks etc all make a difference to how a card performs.

It can get a bit complicated, especially between architectures

 

ohhh PP Chinese.also a major problem that i have is i cant boot to w7 64bit and i think its coz my activation key is wrong.can anyone tell me where exactly the key is located on my hdd so find it and change it .i cant access to regedit coz am not booted in w7 64bit.
thx

 

Flashed your bios with the one for 1722 didn't you? And I suppose you missed this post...

 

I was wondering if the MIC label, to the right of the webcam, is an actual mic? If so how does one activate it to utilize it?

 

yea thats true .i missed it anw i restore my pc 2 months back and now its ok..and stock bios..as my friend said..live with 4% overclock

 

you don't really need to activate it , if your right click on the speaker icon ,select sounds then advanced tab , you can configure it so that other applications that supports MIC can control it (Like msn , skype & even games)

Sometimes when using turbo , the clock speed goes up to 2.7 on 1.300v for a sec or 2 then goes down to 2.4 ... wonder if manually increasing the volts would help

 

Thats IDA (What i was working on,)

You know you can perminantly trigger it for say... IE?

 

Yeah that site is where I got onto the GT725. Great, easy to understand list running from lowest 3dmark scores to highest.

 

Yes you will notice nVidia cards can have hundreds of times more transistors than the ati equivalents, but the ati card will have many times more shader pipelines. Like Alexrose said, it gets very complicated when comparing different architectures.

 

Great to have you back too Rorsch, that was what I call a temporary ban lol.

EDIT: My next post will be the 1722 cleaning guide peoples. I know a couple of people are keen, so it'll be up sometime today.

 

lol thanks, I learned a good lesson the last few days and no it has nothing to do with my ban . Motorcycles+ laptop = not good. I was getting worried lastnight, about my laptop temps because they never went past 75c before and all of a sudden they were hitting 85c. Well I got back home and cleaned everything out and decided I would take a look at the thermal paste. Turns out the vibration from the motorcycle had vibrated a lot of the thermal paste away.
Reapplied the thermal paste and also used some motorcycle chain lube on the fan to see if that might help a little and now my temps are lower than before, down to 70c. I will definitely be getting a better backpack for when I take my laptop with me or maybe I just shouldn't take it with me on the motorcycle lol.

Edit good good for some reason my laptop isn't going over 64C while gaming, the 70c temps earlier were from furmark burn in test. I guess that shows how important proper heatsink contact is.

 

FK!!!
same price as my gt725-212us WAS...

i hate my self.. ( worst buy ever

 

>.> thats a preorder though, and I heard there will be delays. Plenty of time to sell your current laptop.

 

hehe true but i love my lap..i have it 6months and no scratches AT ALL no finger prints no dust!!
just new.and am studing right now.i cant live without laptop.i have 2000pounds i can buy it anytime i want but i wont have money to eat then Ppp

anw no chance to change within 3 years )
am not idiot!

 

64 degrees gaming and 70 degrees load sounds awesome! What paste did you use? That is definitely something to be proud of.

 

Ok this post is intended to be a guide on cleaning the GT725.

It isn't a very long guide, the bulk of the work is in removing/putting parts back in.

Remember to remove the battery and ac power first too.

Okay, the first thing you need to do, (this step is optional) is contact MSI and get confirmation that opening up the laptop to clean it will not void your warranty. The response can be mixed for some reason, I got 2 yesses and a no . Also, if you feel uncomfortable opening up your laptop, I would recommend not going ahead.

(See Step 1.jpg) Ok now to remove the panel on the bottom, unscrew the 4 screws, circled in red in the picture. The screw circled in blue looks like it would need to be unscrewed, but it doesn't, so leave it. Then lift the panel out by getting your finger under the concave bit and lifting straight up (yellow arrow). Once this corner is out, gently pull the whole panel in the direction of the white arrow.

(See Step2.jpg) This is the only fan. Again, there are 4 screws you will need to unscrew, circled in red in the picture. The plug circled in white is the power for the fan, and it must be removed so you can pull the fan out. The plug circled in blue doesn't have to be removed, I found it helped to get the screws/fan out.

(See Step3.jpg) Once the fan is out, you can clearly see the vents for the heatsinks. Compressed air is the best thing for this, although you could easily use an old toothbrush and vacuum (be careful vacuuming inside your laptop though!). If using compressed air, blow from the inside out, as indicated by the red arrows.

With the fan out, stick something inside the fan to stop it from spinning, then give it good blow with compressed air. If you don't stop if from spinning first, you could damage it with compressed air by spinning it too fast.

(See Step4.jpg)(This stage is optional) If you really want to get rid of all that dust, use a cotton bud dipped in metho and wipe all the blades of the fan individually. Its a bit tedious, but as you can see from this picture I was able to get rid of some serious crap.

Ok you're done! Just put the fan back in, screw all 4 screws back in, plug everything back in. Put the bottom panel back on, 4 screws again. Put the battery back in, and thats it.

This isn't intended to lower your temps too significantly, but it should be done as a general maintainance of your laptop to prolong the life of the parts, probably once every 6 months or so, depending on how dusty the environment you use it in and how often you use it.

I hope this guide helped everyone, please remember to give me feedback!

Cheers

 

AS5 not my preferred paste, but just what happened to be laying around. I really think it might have had more to do with lubricating the fan. It sounds a little louder now, but at the same time it also sounds like its running faster.

 

Hmm might have too look into that myself.

Hey thanks for the great post! The pix are excellent, btw. I do have a minor nit to pick. I would have recommended disconnecting the power and battery before proceeding.

 

' I didn't even notice the battery was in, definitely should do that.

 

All I got was static from the recording.

 

Yeah I already wrote it in, 3rd line down...

Just after I took that picture I noticed it too, and then took it out.

Cheers for that though

 

thank you, great guide, + rep

 

Cheers mate

 

What's a student doing with £2000 CLEARLY they aren't poor as they make out

 

I love our machines, and there not getting too old to be fair, the 5870 apparently is running with a 128mb memory bus?

Still it shows a 30% increase, but to be honest, it'l most likely be coupled most the time with 1080p screens, because it will handle games at that res.

Im running an advent so im pretty happy xD, and the MSIs can either use both 1680x1050 or 1920x1080.

 

actually i had 2500 but i spend for clothes 500


OMG 80usd lower...anw dont show me more gaming laps..pls

 

omg is that website safe to buy??
http://www.provantage.com/
ITS SOO CHEAP!!


also thx lambo!!! while i was cleaning my lap i didnt stop fan spinning with compressed air ://// i never thought that maybe i will brake it..but it was fun ppPP
how i know if i broke it? temps are fine no noise i think

 

Did you succeed ?

@ Rorschach , Loving your sig

 

IDA seems to work flawlessly when the computers in the right circumstance, now this i'm quite happy about, although i've only really done one thread at the moment (and 2.7 ghz for you on a single app is pretty mad ) assuming it works with yours, ill drop some instructions soon!

 

42C cpu and 48C gpu : idle
am i good???

 

Kool can't wait apparently quads don't have IDA .. instead it got DDA ( Dual Dynamic Acceleration ) which right now according to HWinfo is correct as 2 of my cores are @ 2.7 and the other 2 @ 2.4 ..

"Dual Dynamic Acceleration technology boosts CPU performance by means of increasing frequency of any one CPU core when any other CPU core is idle, that is when the other CPU core is in Deep Sleep or lower power state. The CPU may also increase frequency of two of its cores when two other cores are idle. Frequency in Core 2 Quad Mobile CPUs is usually increased by 266 MHz.
This feature was introduced in Intel Core 2 Quad Mobile CPU family and is applicable only to quad-core CPUs. Similar feature in dual-core processors is called Intel Dynamic Acceleration technology. Newer Intel microprocessors based on Nehalem core utilize improved version of IDA called Turbo Boost Technology."

Your temps are fine , why did you buy a GX720 ? Got any mail from msi regarding new ...... ?

 

no my friend they dont talk strait but i state my question again and am waiting ..maybe they dont know .i will inform u if i have a strait answer but i dont thing so. am still using what u send me. i bought gx720 for my bro

 

How much did you paid for it if you don't mind me asking well usually they are pretty fast at replying to email .. I sent them one on Friday and got my reply this morning

I want one http://www.pcpro.co.uk/news/354688/alienware-m11x-gaming-laptop-video-first-look

 

600euro + 100euro shipping

 

Check this site: ResellerRatings.com

 

Hmm, odd, i dont have fsb gains, i can get up to 3 cores using this *strange technology?*

Multipliers change as far as im aware.

But go ahead and go to youtube, load up a hd video, go to task manager, right click all the iexplorer.exe blah blah, then set afinity to 1, then have cpu-z read the clock and you should find that it either fsb clocks (as dda says) or multi ups like ida i think.

 

am little lost.what are these things are u trying to do? i lost posts.can u pls tell me with few words?

 

Ok done it , and it's the multiplier that goes up(tried with 1 core and 2) ... which is more accurate ? cpuz or hwinfo ?

 

265.9 x 10 seems more accurate, atleast i think thats how multipliers work . So 2659 on the clock.

I wish we could, i dont know take control of this feature to use it for safe overclocking @@,

Its built into the processor so its safe too! hmm we need someone that understands this technology better.

 

There trying to get a precise overview of the CPU clock speeds and memory module data comming from the computer.

Endless tinkering to try and extract that extra ninth yard out of our favourite lappy.

Still interesting non the less

 

We want more miles!!!

I wonder what IDA/DDA is a feature of though, bios, processor?

Need to interface with it .

 

Dont Do Anything.

leave it be, poor thing

 

Haha, it'd be good, overclocking with a feature which is fairly useless anyway .
