GeForce 9800 GTX+ vs Radeon R9 M265X

Intro

The GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory runs at a speed of 1100 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M265X, which features core clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M265X should perform a little bit faster than the GeForce 9800 GTX+ in general. (explain)

Radeon R9 M265X 72000 MB/sec
GeForce 9800 GTX+ 70400 MB/sec
Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX+ should be quite a bit (more or less 105%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce 9800 GTX+ 47232 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 24232 (105%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9800 GTX+ is the winner, by a large margin. (explain)

GeForce 9800 GTX+ 11808 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 2608 (28%)

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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
