Radeon HD 7850 vs Radeon R7 260X
Intro
The Radeon HD 7850 comes with a GPU core clock speed of 860 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1200 MHz through a 256-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.Compare those specifications to the Radeon R7 260X, which comes with 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 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory 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.
