Nvidia GT 550M vs Radeon 6750M

I'm looking forward to buying a laptop in about a month or two, and I've ben eyeing two laptops that have the said graphic cards. Both are 14" with 1366x768 resolutions and I would like to play games such as Crysis 2 and Skyrim in the future.

My question is which one of the two are better for gaming? I understand Nvidia has a better architecture than AMD but the latter has GDDR5 for its memory compared to 550M's GDDR3. I don't quite understand discrete graphics and such, having been on integrated graphics for years. Any help would be appreciated.

 

The 6750m an underclocked 6770 and that thing is on par/slightly better than the 144 shader 555m. The 550m has only 96 shaders (albeit at higher clock speed) so it's a bigger step down than the 6770 to 6750. So I think the 6750m is the faster gpu.

 

the 6750m is a better by some 15-20% and where did you get that the nvidia arch is better?

 

Just reading it off from Notebookcheck, wherein "the number of shaders is not comparable to the 1D cores of current Nvidia GPUs". I'm just confused by the article on the 550M that says it is on the same level with 6750M when equipped with a GDDR3.

 

nah its not far from it, it might be something close if they put GDDR5, not GDDR3, since that is one of the versions of the GT 555m

nah that dont say at all that either arch is better, its just that they fill different niches

 

The MacBook Pro users seem happy about their 6750m with 1gb GDDR5 so that card cant be all that bad.

 

its actually quite good, it can play most games on the mbp high res screen (1680*1050) on high ultra mixed settings

and before anyone starting pulling out the m14x, that is a gaming machine, and thus gaming is a priority, thus it should have a gaming gpu, meaning gtx, to actually pack almost the same power as the mbp 15, is quite ridicule to say the least, arent macs ovepriced and underpowered

 

Is this a 550M with GDDR5?

 

the 550m with gddr5 is named gt 555m

 

But doesn't the 555M have more shaders than the 550M, not just the memory used? GDDR5 & DDR3 can be used for the 555M.

@Kevin: No, its a DDR3 type.

 

There are at least 3 different versions of the GT 555M. One of them has 96 shaders and 128-bit bus. The other two have 144 shaders (one with 128-bit bus and the other with 192-bit bus).
Everything else the same, I'd go with the AMD 6750M.

Cheers!

 

not to mention the difference in rops

 

Sorry, I know it’s an old thread but I’m in the same situation.

Why is everyone recommending the 6750m? The 6750m is beaten on most benchmarks on notebookcheck, the same for the majority of the game tests (one or two go to the 6750 by a couple of fps, quite a few go to the 550 by a lot more than that). Are these results just to do with the hardware tested? I have not been keeping up with gpus for a while now so I could do with the advice, or any links to tests that show the 6750 being better if that is the case (not just technical numbers, they don't always show which is better between two different architectures even when you know more than the little I do).

Thanks

 

Rather than try to argue either card by putting up a bunch of links to synthetic benchmarks or old game benchmarks with older drivers... First understand that both are mid tier cards and will play most games on medium settings. The lower the resolution the higher the game settings you should be able to enable. Both cards are capable of playing most new games with driver updates. Just set realistic expectations of a mid tier GPU and you should be happy either way. Also remember that certain games may have partnered more closely with AMD or NVIDIA during the coding process and therefore the game may run more fluid on the respective GPU. Just do your best to judge the overall notebook package your looking at based on Quality, Price and Hardware. good luck

 

The stock Nvidia GT550M has 144 cuda core shaders... There was some rather interesting threads about why Nvidia on its own website advertises this card as having 96.

Every person who ran afterburner or some other video card monitoring software including Nvidias own system monitor shows 144 shaders.

As for performance I have an L702X with the GT 550M card and can say it is a decent mid range card but very few new games can be played at high settings. For some reason some games also seem to prefer the Radeon video cards for performance even when clocks and memory are similar.

I would say some of the previous posters are correct about the memory bus the higher GDDR5 memory with a higher bus on the GPU "should" outperform the DDR3 memory of the 550M.

Personally I like optimus and dont mind playing at medium to low settings so I went with the Nvidia card.
