GeForce 810M vs GeForce 8500 GT

Intro

Compare those specifications 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 comprised of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

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

Texel Rate

The GeForce 810M should be quite a bit (more or less 64%) better at AF 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 will be quite a bit (approximately 64%) more effective at AA than the GeForce 8500 GT, and capable of handling higher screen resolutions without slowing down too much. (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 (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels 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 amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
