GeForce GTX 860M vs Radeon HD 4730

Intro

Compare those specs to the Radeon HD 4730, which features clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs as well as 32 TAUs and 8 ROPs.

Radeon HD 4730		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce GTX 860M is much (more or less 242%) more effective at AF than the Radeon HD 4730. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 54112 (242%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 860M is superior to the Radeon HD 4730, and very much so. (explain)

GeForce GTX 860M		12752 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 7152 (128%)

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 max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
