GeForce 8800 Ultra vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which features core speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. 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 Ultra should in theory perform quite a bit faster than the Radeon R5 M230 in general. (explain)

GeForce 8800 Ultra		103680 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 87680 (548%)

Texel Rate

The GeForce 8800 Ultra should be quite a bit (about 151%) better at texture filtering than the Radeon R5 M230. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 23568 (151%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 Ultra is the winner, by far. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 11568 (371%)

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 megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 applied in one second. This 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
