Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon RX 460
IntroThe GeForce GTX 460 SE features a GPU clock speed of 650 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 256-bit bus. It also is made up of 288 Stream Processors, 48 Texture Address Units, and 32 ROPs.
Compare those specs to the Radeon RX 460, which makes use of a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 460 should in theory perform a bit faster than the GeForce GTX 460 SE in general. (explain)
Texel RateThe Radeon RX 460 should be quite a bit (more or less 96%) faster with regards to texture filtering than the GeForce GTX 460 SE. (explain)
Pixel RateThe GeForce GTX 460 SE should be a little bit (about 19%) faster with regards to anti-aliasing than the Radeon RX 460, and 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
