GeForce GTX 880M vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which has a core clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

GeForce GTX 880M		128000 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 54400 (74%)

Texel Rate

The GeForce GTX 880M is much (more or less 385%) better at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 96912 (385%)

Pixel Rate

The GeForce GTX 880M should be a lot (about 173%) better at FSAA than the Radeon HD 5750 1GB, and will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 880M		30528 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 19328 (173%)

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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out 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 graphics 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
