GeForce 810M vs GeForce 8500 GT

Intro

Compare all of that to the GeForce 8500 GT, which has GPU core speed of 450 MHz, and 512 MB of DDR2 memory running at 400 MHz through a 128-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the GeForce 810M should theoretically be a small bit superior to the GeForce 8500 GT overall. (explain)

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

Texel Rate

The GeForce 810M should be much (approximately 64%) better at anisotropic 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 quite a bit (more or less 64%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and able to handle higher screen 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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
