GeForce 810M vs GeForce 9500 GT 512MB GDDR3

Intro

Compare those specs to the GeForce 9500 GT 512MB GDDR3, which makes use of a 55 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 RAM works at a speed of 800 MHz on this particular card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

GeForce 810M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 9500 GT 512MB GDDR3 should be quite a bit (more or less 49%) better at texture filtering than the GeForce 810M. (explain)

GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 2896 (49%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9500 GT 512MB GDDR3 is a better choice, and very much so. (explain)

GeForce 9500 GT 512MB GDDR3		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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
