GeForce 8800 GS vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which comes with GPU clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M385X should perform a lot faster than the GeForce 8800 GS overall. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The Radeon R9 M385X should be much (approximately 133%) faster with regards to AF than the GeForce 8800 GS. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 35200 (133%)

Pixel Rate

The Radeon R9 M385X will be quite a bit (approximately 167%) better at full screen anti-aliasing than the GeForce 8800 GS, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 11000 (167%)

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 largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
