Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.

4 Responses to “Radeon HD 7850 vs Radeon R7 260X”You were wrong with TEXEL RATE... You wrote... 7850 = 64 TMU=55040 TR and R7 260X = 56 TMU = 61600 TR.
My mistake... It's OK! Sorry! 🙂
Uh the 7850 has a TDP of 150Watts watts not 130Watts. That's why it is such a great overclocking GPU. You could make it perform almost even with a stock 7870 if you could get a high stable overclock.

This might be true with a factory overclocked card. but Stock clock the 260X has a higher texel rate. That does not mean it is faster. You have to keep in consideration the other numbers.
