GeForce 9800 GTX vs Radeon R9 M265X

Intro

The GeForce 9800 GTX comes with a GPU core speed of 675 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare that to the Radeon R9 M265X, which uses a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M265X should theoretically be a little bit superior to 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 will be much (about 88%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 20200 (88%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9800 GTX is superior to the Radeon R9 M265X, though only just barely. (explain)

GeForce 9800 GTX 10800 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 1600 (17%)

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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
