GeForce GTX 470 vs Radeon R9 M290X

Intro

The GeForce GTX 470 has a core clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Compare that to the Radeon R9 M290X, which features a core clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 32 ROPs.

GeForce GTX 470 133920 MB/sec
Difference: 19680 (15%)

Texel Rate

The Radeon R9 M290X will be quite a bit (about 100%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)

Radeon R9 M290X 68000 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 34008 (100%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M290X is the winner, but only just. (explain)

Radeon R9 M290X 27200 Mpixels/sec
GeForce GTX 470 24280 Mpixels/sec
Difference: 2920 (12%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to get to the max fill rate.
