GeForce GTX 870M vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which features core speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Radeon HD 4350		4600 Mtexels/sec
	Difference: 100792 (2191%)

Pixel Rate

The GeForce GTX 870M will be much (more or less 882%) more effective at anti-aliasing than the Radeon HD 4350, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 870M		22584 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 20284 (882%)

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 megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
