GeForce GTX 260 216SP 55 nm vs Radeon R9 M385X

Intro

The GeForce GTX 260 216SP 55 nm uses a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this model. It features 216 SPUs as well as 72 Texture Address Units and 28 ROPs.

Compare those specs to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory works at a speed of 1500 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 260 216SP 55 nm should theoretically be a bit superior to the Radeon R9 M385X in general. (explain)

GeForce GTX 260 216SP 55 nm 111888 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 15888 (17%)

Texel Rate

The Radeon R9 M385X will be a lot (more or less 49%) more effective at anisotropic filtering than the GeForce GTX 260 216SP 55 nm. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 260 216SP 55 nm 41472 Mtexels/sec
Difference: 20128 (49%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M385X is a better choice, not by a very large margin though. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce GTX 260 216SP 55 nm 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
