GeForce 8800 GTX vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which makes use of a 28 nm design. AMD has set the core frequency at 780 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this particular card. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTX, in theory, should perform much faster than the Radeon R5 M230 overall. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce 8800 GTX is a lot (more or less 136%) faster with regards to anisotropic filtering than the Radeon R5 M230. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 21200 (136%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GTX is superior to the Radeon R5 M230, and very much so. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 10680 (342%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
