GeForce 8800 GS vs Radeon R9 M265X

Intro

Compare all of that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR5 memory works at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M265X should theoretically perform a lot faster than the GeForce 8800 GS in general. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The GeForce 8800 GS should be a little bit (more or less 15%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce 8800 GS		26400 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 3400 (15%)

Pixel Rate

The Radeon R9 M265X will be much (approximately 39%) faster with regards to FSAA than the GeForce 8800 GS, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 2600 (39%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
