GeForce 810M vs GeForce 930M

Intro

Compare those specs to the GeForce 930M, which uses a 28 nm design. nVidia has set the core speed at 928 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce 930M should be quite a bit (approximately 277%) more effective at AF than the GeForce 810M. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 16368 (277%)

Pixel Rate

The GeForce 930M will be a lot (more or less 151%) better at anti-aliasing than the GeForce 810M, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 4472 (151%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
