GeForce 810M vs Radeon HD 4750

Intro

Compare all of that to the Radeon HD 4750, which features GPU core speed of 730 MHz, and 512 MB of GDDR5 RAM running at 800 MHz through a 128-bit bus. It also is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 4750		75 Watts
	Difference: 60 Watts (400%)

Memory Bandwidth

In theory, the Radeon HD 4750 should be quite a bit faster than the GeForce 810M in general. (explain)

Radeon HD 4750		51200 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 36800 (256%)

Texel Rate

The Radeon HD 4750 will be much (about 296%) better at AF than the GeForce 810M. (explain)

Radeon HD 4750		23360 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 17456 (296%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 4750 is a better choice, by a large margin. (explain)

Radeon HD 4750		11680 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 8728 (296%)

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 maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
