Compare any two graphics cards:
GeForce 9600 GSO 768MB vs Radeon RX 470 4GB
IntroThe GeForce 9600 GSO 768MB has a GPU clock speed of 550 MHz, and the 768 MB of GDDR3 memory is set to run at 800 MHz through a 192-bit bus. It also is comprised of 96 SPUs, 48 TAUs, and 12 Raster Operation Units.
Compare that to the Radeon RX 470 4GB, which has a GPU core clock speed of 926 MHz, and 4096 MB of GDDR5 RAM running at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470 4GB should in theory be quite a bit faster than the GeForce 9600 GSO 768MB in general. (explain)
Texel RateThe Radeon RX 470 4GB is quite a bit (approximately 349%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)
Pixel RateThe Radeon RX 470 4GB should be quite a bit (about 349%) better at FSAA than the GeForce 9600 GSO 768MB, and also should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 per second. This number is worked out by multiplying the total amount of texture units of the card 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 applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
