Difference: 15104 (13%)

Texel Rate

The Radeon RX 460 2GB should be a lot (approximately 22%) better at texture filtering than the Radeon HD 4850 X2 512MB. (explain)

Radeon RX 460 2GB 61040 Mtexels/sec
Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Difference: 11040 (22%)

Pixel Rate

The Radeon HD 4850 X2 512MB is a small bit (more or less 15%) more effective at FSAA than the Radeon RX 460 2GB, and also capable of handling higher resolutions better. (explain)

Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Radeon RX 460 2GB 17440 Mpixels/sec
Difference: 2560 (15%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
