GPU Battle: Radeon HD 7660G vs Radeon HD 7670M vs GT 630M

“Actually, the performance of the 7660G is too close to the 630M and 7670M to justify a premium”


Entry midrange GPUs battle. The Radeon HD 7660G found in the Trinity A10-4600M CPU, the Radeon HD 7670M which is actually a rebranded Radeon HD 6650M and the GT 630M which is actually a rebranded GT 540M. You can find them all in laptops of the same price range more or less, competing with each other like it’s the only thing that matters in the world.

Well, first lets see some dry info.


Model Core, shaders (vertex / geometry / pixel) memory and bandwidth Core speed
Radeon HD 7670M Thames XT, 480 unified : 24 : 8, 40nm process DDR3@900MHZ,  28.8GB/s 600MHZ
GT 630M / GT 540M Fermi (GF108), 96 unified : 16 : 8, 40nm/28nm process DDR3@900MHZ, 28.8GB/s 672MHZ
Radeon HD 7660G (A10-4600M) Trinity, 384 unified : 24 : 8, 32nm process System memory 497 – 686 MHz

The 7660G is based on the newer VLIW4 architecture and the 7670M / 6650M on the older VLIW5 architecture. Performance for the same clock and with the same memory bandwidth should be at least similar in most cases between the VLIW4 and VLIW5 and sometimes the newer and improves VLIW4 chips should have an advantage.



Now, for actual performance. Based on numbers from HotHardware, notebookcheck and Anandtech we can say that the Radeon HD 7670M and GT 630M are averagely of the same performance level. Of course, the performance you’ll get depends also on drivers and the system used.

Now, as for the 7660G against the GT 630M / HD 7670M – we have to remember that the 7660G does not come as a dedicated GPU, but as a part of a whole APU with the A10-4600M CPU. The A10-4600M cores are slower than the (more or less) equally clocked Intel I5 cpus usually used for the 630M and 7670M benchmarks and thus, the results we see do not show the 7660G GPU potential itself plus, I do believe that as drivers will get more mature, we’ll see better performance.

That being said, in 3DMark 11 and 3DMark Vantage  GPU Performance scores, the 7660G is positioned around the GT 630M (link). The actual FPS numbers in games, however, show that the difference between the GT 630M (OC’ed version, at least) and the 7660G can get as high as 50%  like in portal 2 (768p resolution, medium settings) and “Batman: Arkham City. But averagely, even with a fast I5 or I7, the GT 630M would be only 10%-20% faster. Interesting enough, the 7660G comes very close to the GT 630M and 7670M in many heavy duty titles, like BF3, Skyrim and more. Additionally, AMD 7660G has – probably – a significant advantage over Nvidias’ GPUs in Civilization V and the 7660G actually equals the GT 630M.

Actually, the performance of the 7660G is too close to the 630M and 7670M to justify any premium. Keep in mind that the A10-4600M chip TDP is 35W – it includes both a fast quad core cpu and a very good GPU, so you would probably get a better  battery performance with one of this compared to some of the older cpus, like the I3.




The A10-4600M + 7660G combination will give you a lot for your money, if you can get it for a good price. There is no need to try and find some 7670M / GT 630M equipped laptops if you don’t really need the extra performance. True, You’ll find it hard to find an A10-4600M laptops for less than 500$ and for that price you can get the 7670M or GT 630M anyway, but the point is that sometimes you can find the laptop you want with an A10-4600M cpu while you won’t find what you want with a GT 630M or Radeon 7670M.

A good deal of a A10-4600M laptop should be in the 500$ range.


If you are wondering how’s the 7660G competes with AMD’s previous generation 6620G or Intel’s HD 4000, read here.

  • kevin hernandez this is copy of the link of the computer that I have, but I don’t now if AMD Radeon HD 7660G Graphics is a removable graphics card or not, please help I want to play better games… thank you

    • Hi

      No, it is not – it is integrated with the CPU. There is an option to plug an external GPU but it requires some skill, time and money and I’m not sure it will work.

      Do you know what is your RAM configuration? If not, download the CPU-Z software (free) and install it, then go to ‘Memory’ – what is written in the “Channel” box?

  • Anonymous

    So over all which one is better? AMD Radeon HD 7670M or NVIDIA GeForce GT 630M?

    • depends on the game and besides – the difference isn’t really big even on specific games.

      I think you shoud go with the laptop that has the better price (unless there is another different component)

  • nels

    i wana one good gaming laptop please tell me asap 😛

    • well, what do you need? what is the budget? country of purchase? specific games?

  • rahul

    i in complete confusion….. and need help

    • for gaming?
      please links?

  • sameg

    i have a v3-551g a8-4500 with amd radeon 7640g+7670m with 2 gb dedicated memory and it sucks on playing games like assassins creed 3 and need for speed most wanted(13), and also i have 8gb ddr3… is it a problem of crossfire? since i can´t even play in low quality….

    • assassins creed 3 is a very heavy game. I don’t think it is only a problem in your crossfire. Anyway, you should install the newest drivers from AMD and see what happens

  • kuroro

    Just wanted to let you know that I went with the V3-551G and it’s working out great. Thanks junky!

    • Thank you (-:
      How is its screen?

  • Andre Lopez

    So sorry to bother you, but I don’t know nothing about laptops neither the hardware. I can only pay $630 for a laptop, and I know I wont get much performance for that, but at least I want to be able to run game on medium settings or on low and run smooth. I don’t care about battery life, or if the screen is full hd(no smaller than 15.6”). It has to last me at least 2 years. My only choices right now is:

    Pavilion g7z-2100 17’3 Notebook PC
    AMD Quad-Core A8-4500M Accelerated Processor (3.0GHz/2.1GHz, 4MB L2 Cach
    1GB AMD Radeon(TM) HD 7670M Discrete-Class Graphics
    4GB DDR3 System Memory (1Dimm)


    Acer Aspire V3-771G-6650 Notebook 17’3
    Intel Core i5 2450M(2.50GHz)
    2G NVIDIA GeForce GT 630M
    4G RAM

    thanks a lot.. really

  • Andre Lopez

    This is really frustrating I dont know nothing about laptops but I did my search and cant decide between:

    A8 4500 – Radeon 7670M or i5 2450 – 2G GT 630M

    both have 4g of ram, i just want it for gaming like d3, dw2, bf3. on med.

    pleas, advise me on this decision, you don’t know how grateful i will feel I some one clear this out for me..

    • For the same price?

      The A8-4500M (7640G GPU) can crossfire with the 7670M potentially, but it depends on drivers and in practice it doesn’t work that well in many cases.

      • Andre Lopez

        I dont get it, so should i go with:

        Pavilion g7z-2100 17’3 Notebook PC
        AMD Quad-Core A8-4500M Accelerated Processor (3.0GHz/2.1GHz, 4MB L2 Cach
        1GB AMD Radeon(TM) HD 7670M Discrete-Class Graphics
        4GB DDR3 System Memory (1Dimm)


        Acer Aspire V3-771G-6650 Notebook 17’3
        Intel Core i5 2450M(2.50GHz)
        2G NVIDIA GeForce GT 630M
        4G RAM
