GeForce 810M vs GeForce 8500 GT

Intro

Compare those specifications to the GeForce 8500 GT, which features core clock speeds of 450 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 16 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

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

Memory Bandwidth

Theoretically speaking, the GeForce 810M is 13% faster than the GeForce 8500 GT in general, due to its higher data rate. (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

The GeForce 810M should be much (approximately 64%) more effective at FSAA than the GeForce 8500 GT, and will be capable of handling higher resolutions more effectively. (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
