GeForce GTX 260 vs Radeon R9 M385X

Intro

The GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM is set to run at a frequency of 999 MHz on this model. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.

Compare all of that to the Radeon R9 M385X, which features core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

The Radeon R9 M385X is much (more or less 67%) faster with regards to AF than the GeForce GTX 260. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 24736 (67%)

Pixel Rate

The Radeon R9 M385X will be a little bit (more or less 9%) better at FSAA than the GeForce GTX 260, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 1472 (9%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
