GeForce 810M vs GeForce 8500 GT

Intro

Compare that to the GeForce 8500 GT, which features a clock speed of 450 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce 8500 GT		45 Watts
	Difference: 30 Watts (200%)

Memory Bandwidth

Theoretically speaking, the GeForce 810M will be 13% quicker than the GeForce 8500 GT in general, because of its greater bandwidth. (explain)

GeForce 810M		14400 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 810M should be a lot (approximately 64%) better at texture filtering than the GeForce 8500 GT. (explain)

GeForce 810M		5904 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 2304 (64%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 810M is superior to the GeForce 8500 GT, by far. (explain)

GeForce 810M		2952 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 1152 (64%)

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 (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at 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 the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
