GeForce 810M vs Geforce GTX 770

Intro

Compare all of that to the Geforce GTX 770, which features a clock speed of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

GeForce 810M		5904 Mtexels/sec
	Difference: 127984 (2168%)

Pixel Rate

The Geforce GTX 770 is a lot (more or less 1034%) faster with regards to full screen anti-aliasing than the GeForce 810M, and will be capable of handling higher screen resolutions better. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 30520 (1034%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
