GeForce 810M vs GeForce 930M

Intro

Compare those specifications to the GeForce 930M, which has GPU clock speed of 928 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce 930M is quite a bit (approximately 277%) more effective at texture filtering than the GeForce 810M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce 930M is a better choice, and very much so. (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 (counted in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to get to the maximum fill rate.
