Radeon HD 4870 X2 vs Radeon R7 260X

Intro

The Radeon HD 4870 X2 has a GPU clock speed of 750 MHz, and the 1024 MB of GDDR5 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R7 260X, which has core clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Texel Rate

The Radeon R7 260X will be just a bit (more or less 3%) more effective at AF than the Radeon HD 4870 X2. (explain)

Radeon R7 260X 61600 Mtexels/sec
Radeon HD 4870 X2 60000 Mtexels/sec
Difference: 1600 (3%)

Pixel Rate

The Radeon HD 4870 X2 should be quite a bit (more or less 36%) more effective at anti-aliasing than the Radeon R7 260X, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 4870 X2 24000 Mpixels/sec
Radeon R7 260X 17600 Mpixels/sec
Difference: 6400 (36%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
