Compare any two graphics cards:
GeForce GTX 260 vs Radeon RX 460 2GB
IntroThe GeForce GTX 260 features a clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and uses a 65 nm design. It is comprised of 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.
Compare those specs to the Radeon RX 460 2GB, which has a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 460 2GB, in theory, should be a little bit faster than the GeForce GTX 260 overall. (explain)
Texel RateThe Radeon RX 460 2GB is quite a bit (approximately 66%) faster with regards to texture filtering than the GeForce GTX 260. (explain)
Pixel RateThe Radeon RX 460 2GB is a bit (more or less 8%) better at FSAA than the GeForce GTX 260, and should be capable of handling higher resolutions without losing too much performance. (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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated 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 better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 is calculated 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 in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
