GeForce 810M vs GeForce 930M

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same 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 running with high levels of AA is important to you, then the GeForce 930M is superior to the GeForce 810M, 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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface 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 bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
