GeForce 810M vs Radeon HD 4750

Intro

Compare all of that to the Radeon HD 4750, which features a core clock frequency of 730 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

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

Memory Bandwidth

Theoretically speaking, the Radeon HD 4750 should be quite a bit faster than the GeForce 810M overall. (explain)

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

Texel Rate

The Radeon HD 4750 should be quite a bit (more or less 296%) better at texture filtering than the GeForce 810M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 4750 is superior to the GeForce 810M, by far. (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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
