Compare any two graphics cards:
GeForce 920M vs GeForce 9600 GSO ASUS 512
IntroThe GeForce 920M features a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.
Compare those specs to the GeForce 9600 GSO ASUS 512, which features a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit bus, and uses a 65 nm design. It is made up of 96 SPUs, 48 Texture Address Units, and 12 ROPs.
Power Usage and Theoretical Benchmarks
In theory, the GeForce 9600 GSO ASUS 512 should be a bit faster than the GeForce 920M in general. (explain)
Texel RateThe GeForce 920M should be a small bit (more or less 16%) better at anisotropic filtering than the GeForce 9600 GSO ASUS 512. (explain)
Pixel RateThe GeForce 920M should be a small bit (about 16%) faster with regards to anti-aliasing than the GeForce 9600 GSO ASUS 512, and also will be capable of handling higher resolutions without slowing down too much. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
