Radeon HD 7730M Review
Radeon HD 7730M, codenamed 'Chelsea LP', is a fast-middle-class GPU part of the Mobility HD 7000M Series released by AMD in 2012.
It's based on the new GCN (Graphics Core Next) architecture and therefore not related to any of the previous AMD GPUs. The core-clock will range from 575MHz to 675MHz, and will be decided by the laptop manufacturer, probably according to the cooling system.
Very Demanding games, like Metro 2033, The Witcher II and Max Payne 3, should run smoothly at medium settings, while less demanding games, such as Crysis 2 and Skyrim V, might be playable with high settings and attractive resolutions.

ok i overclocked core clock to 750mhz and memory was 900mhz

temperatures were rock solid 60'c which was quite good i think

My scores here,complete stock frequencies ,no overclock.
i did this benchmark after playing crysis 2 for a hour and GPU temperature reached 58'c so maybe cpu and gpu are throttling.

I have a laptop with an amd A8-4500m Processor, paired with this 7730m GPU. i knew at the beginning the integrated 7640g couldnt be crossfired with the 7730, i just thought it would be handy for low power gaming on the go. HOWEVER since i upgraded to i think it was around version 12 beta but also the current Catalyst 13.5 Beta Driver i have an 'enable dual graphics' option in the CCC. I tested dual graphics in dx11 crysis2 and tomb raider.....

......and system monitor shows both gpus working. I also get the 'dual graphics' logo in the top right corner of the screen. Performance seems worse than the 7730 on its own and i also get bizzarre screen tearing. I'm just curious because this seems odd since i shouldnt be able to pair them at all? Is this a new feature they're implementing? Universal dual graphics cabability?

are you talking about memory clocks or core clocks??
can you explain??
i can get core clocks 750mhz max on Afterburner, on which after 705mhz, AMD driver crashes, and memory to 990mhz..

what?? where you got this info??
and it does'nt work that way, numbering system is always different for each GPU generation, you just can't guess the performance by looking at the numbers, take this year's card for example, according to notebookcheck, 7730m-8790m and 7730m>>>>>8830m, so numbering does'nt matter here, what matters is how the GPU performs..

hey Pip, why GD score dropped from 6 to 5???
DDR3 640m is rated 6, and it's equal, if not better to it???
Please correct it..

yes, that's what i mean, and 640m is 6 GD Rating..
A card like this reaching 2300P on 3d Mark 11 deserves atleast 6.. :(
Pip
11:37 Jan-01-2013

Some ranks were adjusted based on real game benchmarks rather than 3D Mark Scores. For example if I were to rank 7660G based on the 3D Mark Score I would rank it as high as a GT 650M. Now we all know that's not its true performance. Even so, 7730M is behind GT 640M even on 3D Mark and on all benchmarks. That's why it's ranked lower. It's just a coincidence that this one is a 5 and 640M a 6. The different in % is what matters.

really, then GD has gone down in terms of quality, i am following a forum where users own both 14R (640m) and 15R (7730m), and mostly 7730m beats 640m hands down, 640m wins where game is heavily nvidia optimized (Arkham city, MP3)..
You should know that GCN based architecture of AMD is far better than nvidia kepler, and even outside gaming, GCN beats kepler in terms of performance..
So you should check overall performance for ratings..

To all the owners of this card, can you share your 3DMark 11 scores, i am posting mine. (These scores are after a slight overclock to Core speed: 665Mhz and using Catalyst 12.11beta8)

yes, coz both are same cards, 7730m is supposed to be the slightly downgraded DDR3 version of 7750m, so 3DMark 11 detect it as 7750m..
