Compare any two graphics cards:
GeForce GTX 275 vs Radeon RX 460
IntroThe GeForce GTX 275 comes with a GPU clock speed of 633 MHz, and the 896 MB of GDDR3 memory runs at 1134 MHz through a 448-bit bus. It also features 240 SPUs, 80 Texture Address Units, and 28 ROPs.
Compare those specifications to the Radeon RX 460, which comes with a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 275 should theoretically be a little bit better than the Radeon RX 460 in general. (explain)
Texel RateThe Radeon RX 460 is much (more or less 21%) more effective at AF than the GeForce GTX 275. (explain)
Pixel RateThe GeForce GTX 275 will be a little bit (about 2%) more effective at full screen anti-aliasing than the Radeon RX 460, and also should be capable of handling higher resolutions more effectively. (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 largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
