GeForce 9600 GSO ASUS 512 vs Radeon R5 M255

Intro

Compare that to the Radeon R5 M255, which has a clock speed of 940 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce 9600 GSO ASUS 512 is a lot (more or less 40%) more effective at AF than the Radeon R5 M255. (explain)

GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 7600 (40%)

Pixel Rate

The Radeon R5 M255 is a little bit (approximately 14%) faster with regards to AA than the GeForce 9600 GSO ASUS 512, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R5 M255		7520 Mpixels/sec
GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
	Difference: 920 (14%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
