GT 540M Performance

I came across the Asus N53SV the other day and it looks good to me but I was wondering if anyone else has a laptop with a GT 540M and how it compares to the 5650/6550. Also, does anyone know how overclockable it is?

 

The GT 540M is a little better than the 5650, but worse than the 5730.

 

Actually, the GT 540m is quite a bit faster than the HD 5650, and a little faster than the HD 5730:

NVIDIA GeForce GT 540M - Notebookcheck.net Tech

ATI Mobility Radeon HD 5650 - Notebookcheck.net Tech

ATI Mobility Radeon HD 5730 - Notebookcheck.net Tech

 

It's right between them in most of those games.

 

So, would you consider the GT 540m faster than the HD 5650, but about even with the HD 5730?

 

I'm sticking with smack in the middle.

By the way, I'm not looking at the synthetic benchmarks, nor am I looking at the games where the rankings seem random.

 

Honestly, notebookcheck is a nice place to get a idea of where your GPU is at. It isn't by any means a definitive answer to all mobile GPU Q&A. As an example, the site doesn't take into account drivers for increase in performances. Another example is laptop manufactures can do whatever they want to a card (lower clocks, undervolt, etc...) and still call it a 540m or 5650m.

 

Thanks guys, those links are great but does anyone know just how far the GT 540M can be overclocked? I know the 5650 is a great overclocker but how about the GT 540M?

 

It really depends on your luck. It should be a good overclocker, I think. Still, that doesn't mean much if you're unlucky. I can't get any sort of stable OC on my 5650 at all.

 

I guess it depends on your luck then.I guess I'm going to get me a Asus N53SV!

 

for references,
my GT 425M OC stable to 700/1400/860.

For daily usage I decrease to 675/1350/860.

Clock can go higher but cooling/power brick is not enough for NP5135

 

How much of a difference is there in terms of fps between the stock clock and the OC?

 

you can compare several card with the same core's default frequencies:

Clevo 425M: 560/1120/700
435M: 650/1300/800
525M: 600/1200/900
540M: 672/1344/900
550M: 740/1480/900

My Clevo 425M OC: 675/1350/860

This probably can give you some idea on how OCed 425M performs.

I haven't tested the difference in terms of frames. But the difference is noticable when playing fast paced FPS.

Not quite scientific just for reference.

 

Since the GT 540M is a overclocked GT 435M, I should be able to get some more juice out of it. Thanks for the references!

 

Yeah, the medium-power notebook GPU industry for 2011 is all rebranding of 2010 GPUs, quite disappointing really.

 

at least AMD launched new products in the mid range...

 

As said above, this is not the case with AMD. The 6600M/6700M cards are new.

Also, I think NVidia's GT 555M is a new card.

 

the GT 555M has GF106 core, i.e. the same as GT 445M

All current announced NVIDIA's 5xxM series using the same core as their respective 4xxM series but with fine-tuned TSMC 40nm process(so clocks better), paired with faster memory.

 

Right, I forgot about the GT 445M...

It's pretty sad that NVidia doesn't seem to care about the low-end and mainstream cards too much, especially since so many OEMs go with NVidia just for Optimus. The cards are still nice, but it would be nice to see a bit more value.

 

I'm pretty sure the HD 6770 is basically a re-brand of the HD 5770 :

ATI Mobility Radeon HD 5770 - Notebookcheck.net Tech

But, you guys know how accurate my GPU info is

 

You accuracy on GPU specifications is just as accurate as a Revolutionary War smoothbore musket!

The 6770M is all new tech with 80 more shader cores. The 5770M's rebrand is the 6570M.

 

Exactly. They could only be the same chip if the 5770 had 80 disabled cores, which it doesn't.

 

Nop the 6750/6770M are not just rebranded cards with a few more SPs, they're definitely a different architecture. They have the improved memory controller and all kind of tweaks featured in Barts and Turks on desktop and improved tesselation performance, among other stuff.

GPU-Z also says it has twice the ROPs (makes sense since it would be an exact Barts Pro chip cut in half), AMD's official page says it doesn't, but then it wouldn't be the first time they screw up on their own GPUs specs.

So 480sp & GDDR5 already gives you quite a decent bump and then Northern Islands managed to achieve more than Evergreen with the same sp count so you can definitely expect some serious leap in performance here.
