GeForce 8800 GT 256MB vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which features a clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is made up of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GT 256MB should in theory be much faster than the Radeon R5 M330 overall. (explain)

GeForce 8800 GT 256MB		44800 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 30400 (211%)

Texel Rate

The GeForce 8800 GT 256MB will be much (more or less 63%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 8800 GT 256MB		33600 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 13000 (63%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 8800 GT 256MB is a better choice, but only just. (explain)

GeForce 8800 GT 256MB		9600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 1360 (17%)

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 largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 ability to reach the max fill rate.
