GeForce 8800 Ultra vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which comes with core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 Ultra, in theory, should be a lot faster than the Radeon R5 M330 in general. (explain)

GeForce 8800 Ultra		103680 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 89280 (620%)

Texel Rate

The GeForce 8800 Ultra is a lot (more or less 90%) better at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 18568 (90%)

Pixel Rate

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

GeForce 8800 Ultra		14688 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 6448 (78%)

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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
