Compare any two graphics cards:
GeForce 9600 GSO ASUS 512 vs Radeon HD 5450
IntroThe GeForce 9600 GSO ASUS 512 comes with core speeds of 550 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 96 SPUs along with 48 Texture Address Units and 12 ROPs.
Compare those specs to the Radeon HD 5450, which comes with a clock frequency of 650 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit memory bus, and makes use of a 40 nm design. It is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce 9600 GSO ASUS 512 should in theory be a lot better than the Radeon HD 5450 in general. (explain)
Texel RateThe GeForce 9600 GSO ASUS 512 should be much (approximately 408%) better at AF than the Radeon HD 5450. (explain)
Pixel RateThe GeForce 9600 GSO ASUS 512 will be quite a bit (about 154%) better at AA than the Radeon HD 5450, and also able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
