GeForce GTX 280 vs Radeon R9 M290X

Intro

The GeForce GTX 280 features a core clock speed of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also features a 512-bit memory bus, and makes use of a 65 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon R9 M290X, which comes with GPU clock speed of 850 MHz, and 4096 MB of GDDR5 memory running at 1200 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M290X 100 Watts
GeForce GTX 280 236 Watts
Difference: 136 Watts (136%)

Memory Bandwidth

Performance-wise, the Radeon R9 M290X should in theory be just a bit better than the GeForce GTX 280 in general. (explain)

Radeon R9 M290X 153600 MB/sec
GeForce GTX 280 141696 MB/sec
Difference: 11904 (8%)

Texel Rate

The Radeon R9 M290X is quite a bit (more or less 41%) faster with regards to anisotropic filtering than the GeForce GTX 280. (explain)

Radeon R9 M290X 68000 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 19840 (41%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M290X is superior to the GeForce GTX 280, and very much so. (explain)

Radeon R9 M290X 27200 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 7936 (41%)

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 over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
