GeForce 8800 GT 1GB vs Radeon R9 M270X

Intro

The GeForce 8800 GT 1GB has a core clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit bus, and makes use of a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 ROPs.

Compare all that to the Radeon R9 M270X, which comes with clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

The GeForce 8800 GT 1GB is a bit (about 16%) better at texture filtering than the Radeon R9 M270X. (explain)

GeForce 8800 GT 1GB 33600 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 4600 (16%)

Pixel Rate

The Radeon R9 M270X is much (approximately 21%) faster with regards to anti-aliasing than the GeForce 8800 GT 1GB, and also capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M270X 11600 Mpixels/sec
GeForce 8800 GT 1GB 9600 Mpixels/sec
Difference: 2000 (21%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few 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.
