AMD Radeon HD 7670M Vs NVIDIA GeForce GT 630M

Postby ihaveaquestion » Thu Jul 05, 2012 9:46 am


The AMD Radeon HD 7670M and the NVIDIA GeForce GT 630M sit just below the top of the line discrete graphics for notebook processors ? Let us compare these to see which one is better.

The AMD Radeon HD 7670M turns out to be 15 to 20% faster than the NVIDIA GeForce GT 630M according to this comparison.

You can play Battlefield 3 (2011) , for example at 25 fps with the Radeon HD 7670M while the fram rate for the GT 630M is 22 - the Radeon HD 7670M is slightly better.

But if you compare the AMD Radeon HD 7670M with the NVIDIA GeForce GT 650M, then latter could come out better.

Examining your comparison I don't see how AMD Radeon HD 7670M turns out to be better than NVIDIA GeForce GT 630M. It shows that GT 630M is better on important benchmark tests such as 3DMark 05 and 3DMark 06. Having in mind that the GeForce GPU also has greater core and shader speeds, I'll definitely spend my money on it.

In 3DMark 11 and 3DMark Vantage, the GeForce wins as well. The comparison you're looking at must be outdated because not only are most of the benchmarks inaccurate, some games do perform better with the GeForce. For example, Fifa 12 (ultra) runs at 72 fps on the 630M, while with the Radeon it runs at 53 fps. t With the GeForce GPU having greater core and shader speeds as well, I would go with the NVIDIA GeForce GT 630M.

The benchmark result 3DMark11.

Radeon HD 7670M 1061

Nvidia 630M 924


Radeon HD 7670M is slightly better in this one - but give a particular game one or the other may be better. Games that are sensitive to CPU power will show different results depending upon the CPU they are paired with.

GT 630M is more power efficient. nVidia has updated this one from 40 nm to 28 nm and the new process has reduced the leakage and it consumes lower power.

For gaming power consumption is not a big deal. All we want is a good performance. If battery life gets lower, who cares. We always have a power plug. Most notebooks now come with dual graphics - an integrated graphics and an extra graphics. So it is not a big deal.

Just wanted to elaborate this thing a little more for the readers who are un initiated into it. An integrated graphics is something that sits inside the CPU itself. It is not as great as the external graphics, but is still more than good enough for display and potentially video transcode. You do not play video games always - and in that case there is really no use of the external graphics. The system shuts the external graphics off to preserve the power consumption. As soon as the graphics utilization need increases, the external graphics in powered on to give you the graphics horse power required.

The problem with the integrated graphics is the memory bus. It does not get its own dedicated memory and has to share it with the CPU. Anyone who has worked on GPU know the importance of fast GPU memory bandwidth. I think Intel's Haswell CPU is looking at this problem and their GT3 variation will have dedicated memory which will boost its performance by 2x.

I know I am deviating a bit from the original HD 7670M Vs GT 630M discussion, but it does not hurt to know where integrated graphics is heading in future. In 2013 Intel will release three variants of Haswell graphics, GT1, GT2, and GT3. There is not much to write about GT1 and GT2 which will of course be better than the HD Grahics 2500 and HD Graphics 4000 that we have in Ivy Bridge today, but the the top end part, GT3, has 40 of the enhanced Ivy shaders ( There are other reports that say there are only 20). By contrast the HD Graphics 4000 has only 4000 today. Even if GT3 does not increase GPU clocks at all, has zero performance enhancements, nor anything else, it will be 2.5x faster than the Ivy Bridge. Ivy Bridge is 2x faster than the Sandy Bridge. So, Haswell is 5x faster than the Sandy Bridge.

Just multiply that with the integrated memory, performance improvement per core and the Haswell is a graphics monster.
