GeForce 8800 GS vs Radeon R7 M265

Intro

Compare that to the Radeon R7 M265, which comes with core speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GS should perform a small bit faster than the Radeon R7 M265 overall. (explain)

GeForce 8800 GS		38400 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The GeForce 8800 GS will be much (approximately 52%) more effective at texture filtering than the Radeon R7 M265. (explain)

GeForce 8800 GS		26400 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 9000 (52%)

Pixel Rate

The GeForce 8800 GS will be a small bit (more or less 14%) better at FSAA than the Radeon R7 M265, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 8800 GS		6600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 800 (14%)

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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
