GeForce GTX 285 2GB vs Radeon R9 M290X

Intro

The GeForce GTX 285 2GB comes with a clock frequency of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also makes use of a 512-bit bus, and uses a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 32 ROPs.

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

Radeon R9 M290X 153600 MB/sec
Difference: 5376 (4%)

Texel Rate

The Radeon R9 M290X is quite a bit (more or less 31%) faster with regards to anisotropic filtering than the GeForce GTX 285 2GB. (explain)

Radeon R9 M290X 68000 Mtexels/sec
GeForce GTX 285 2GB 51840 Mtexels/sec
Difference: 16160 (31%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M290X is superior to the GeForce GTX 285 2GB, and very much so. (explain)

Radeon R9 M290X 27200 Mpixels/sec
GeForce GTX 285 2GB 20736 Mpixels/sec
Difference: 6464 (31%)

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 data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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