Radeon HD 7850 vs Radeon R7 260X


The Radeon HD 7850 makes use of a 28 nm design. AMD has set the core frequency at 860 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Compare those specs to the Radeon R7 260X, which comes with GPU core speed of 1100 MHz, and 2048 MB of GDDR5 RAM set to run at 1625 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied in one second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

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! :)

Blair says:

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.
