GeForce 810M vs Radeon HD 4670 512MB

Intro

Compare those specs to the Radeon HD 4670 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory is set to run at a frequency of 1000 MHz on this model. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 4670 512MB		70 Watts
	Difference: 55 Watts (367%)

Memory Bandwidth

The Radeon HD 4670 512MB should in theory perform quite a bit faster than the GeForce 810M in general. (explain)

Radeon HD 4670 512MB		32000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The Radeon HD 4670 512MB should be much (approximately 307%) better at AF than the GeForce 810M. (explain)

Radeon HD 4670 512MB		24000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 18096 (307%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 4670 512MB is the winner, and very much so. (explain)

Radeon HD 4670 512MB		6000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 3048 (103%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
