GeForce 9600 GT 512MB vs Radeon R9 M390X

Intro

Compare all of that to the Radeon R9 M390X, which makes use of a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

The Radeon R9 M390X should be a lot (approximately 345%) better at AF than the GeForce 9600 GT 512MB. (explain)

Radeon R9 M390X		92544 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 71744 (345%)

Pixel Rate

The Radeon R9 M390X should be quite a bit (about 122%) more effective at full screen anti-aliasing than the GeForce 9600 GT 512MB, and should be able to handle higher resolutions more effectively. (explain)

Radeon R9 M390X		23136 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 12736 (122%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
