Compare any two graphics cards:
GeForce 9600 GSO 512MB vs Radeon HD 4750
IntroThe GeForce 9600 GSO 512MB has a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It is comprised of 96 SPUs, 48 TAUs, and 16 Raster Operation Units.
Compare all of that to the Radeon HD 4750, which uses a 40 nm design. AMD has set the core speed at 730 MHz. The GDDR5 RAM works at a speed of 800 MHz on this specific model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 9600 GSO 512MB should theoretically be a little bit superior to the Radeon HD 4750 overall. (explain)
Texel RateThe GeForce 9600 GSO 512MB will be quite a bit (about 34%) better at anisotropic filtering than the Radeon HD 4750. (explain)
Pixel RateThe Radeon HD 4750 is a bit (about 12%) faster with regards to FSAA than the GeForce 9600 GSO 512MB, and capable of handling higher screen resolutions while still performing well. (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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
