GeForce 8800 GTS (G80) 320MB vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features core speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Radeon R5 M330		14400 MB/sec
	Difference: 48960 (340%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB should be a bit (more or less 20%) faster with regards to anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 4024 (20%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G80) 320MB is superior to the Radeon R5 M330, by a large margin. (explain)

GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 2020 (25%)

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 (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
