GeForce 8800 GS vs Radeon R9 M270X

Intro

The GeForce 8800 GS features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 memory. It features 96 SPUs along with 48 TAUs and 12 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M270X should in theory be quite a bit faster than the GeForce 8800 GS in general. (explain)

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

Texel Rate

The Radeon R9 M270X should be just a bit (approximately 10%) better 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

If using lots of anti-aliasing is important to you, then the Radeon R9 M270X is superior to the GeForce 8800 GS, by far. (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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must 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 AA, HDR 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 amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
