GeForce 810M vs GeForce GTS 450

Intro

Compare all that to the GeForce GTS 450, which features a clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

GeForce 810M		5904 Mtexels/sec
	Difference: 19152 (324%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTS 450 is the winner, and very much so. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 9576 (324%)

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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a 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 clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
