GeForce 810M vs GeForce 9500 GT DDR2

Intro

Compare those specs to the GeForce 9500 GT DDR2, which features GPU clock speed of 550 MHz, and 256 MB of DDR2 memory running at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce 9500 GT DDR2		50 Watts
	Difference: 35 Watts (233%)

Memory Bandwidth

The GeForce 9500 GT DDR2 should in theory be just a bit faster than the GeForce 810M in general. (explain)

GeForce 9500 GT DDR2		16000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 9500 GT DDR2 will be a lot (approximately 49%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9500 GT DDR2 is superior to the GeForce 810M, by a large margin. (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 data (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
