Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum 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.
