Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon RX 460
IntroThe GeForce GTX 460 2GB comes with a core clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 32 ROPs.
Compare those specs to the Radeon RX 460, which has a clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 460 2GB will be 3% faster than the Radeon RX 460 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 460 should be much (more or less 61%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 460 2GB is superior to the Radeon RX 460, and very much so. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
