GeForce 9800 GTX vs Radeon R9 M270X

Intro

The GeForce 9800 GTX makes use of a 65 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR3 memory works at a frequency of 1100 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Compare all that to the Radeon R9 M270X, which uses a 28 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M270X should perform just a bit faster than the GeForce 9800 GTX in general. (explain)

Radeon R9 M270X 72000 MB/sec
GeForce 9800 GTX 70400 MB/sec
Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX should be quite a bit (about 49%) better at texture filtering than the Radeon R9 M270X. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 14200 (49%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M270X is superior to the GeForce 9800 GTX, but it probably won't make a huge difference. (explain)

Radeon R9 M270X 11600 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 800 (7%)

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 (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. 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.
