GeForce 8800 GS vs Radeon R9 M270X

Intro

The GeForce 8800 GS makes use of a 65 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 memory is set to run at a frequency of 800 MHz on this model. It features 96 SPUs along with 48 Texture Address Units and 12 ROPs.

Compare those specifications to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X should be 88% quicker than the GeForce 8800 GS in general, due to its higher data rate. (explain)

Radeon R9 M270X 72000 MB/sec
GeForce 8800 GS 38400 MB/sec
Difference: 33600 (88%)

Texel Rate

The Radeon R9 M270X is a bit (about 10%) more effective at anisotropic filtering than the GeForce 8800 GS. (explain)

Radeon R9 M270X 29000 Mtexels/sec
GeForce 8800 GS 26400 Mtexels/sec
Difference: 2600 (10%)

Pixel Rate

The Radeon R9 M270X is much (approximately 76%) better at AA than the GeForce 8800 GS, and also should be capable of handling higher screen resolutions better. (explain)

Radeon R9 M270X 11600 Mpixels/sec
GeForce 8800 GS 6600 Mpixels/sec
Difference: 5000 (76%)

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 information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
