GeForce 810M vs GeForce 9500 GT DDR2

Intro

Compare all of that to the GeForce 9500 GT DDR2, which features a clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit bus, and makes use of a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 9500 GT DDR2 will be quite a bit (approximately 49%) faster with regards to AF than the GeForce 810M. (explain)

GeForce 9500 GT DDR2		8800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 2896 (49%)

Pixel Rate

The GeForce 9500 GT DDR2 is much (about 49%) more effective at full screen anti-aliasing than the GeForce 810M, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce 9500 GT DDR2		4400 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 1448 (49%)

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 information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
