GeForce 930M vs GeForce GT 340 1GB

Intro

Compare those specifications to the GeForce GT 340 1GB, which features GPU clock speed of 550 MHz, and 1024 MB of GDDR5 memory set to run at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

GeForce 930M		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The GeForce 930M should be quite a bit (approximately 27%) faster with regards to AF than the GeForce GT 340 1GB. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 4672 (27%)

Pixel Rate

The GeForce 930M is quite a bit (more or less 69%) faster with regards to anti-aliasing than the GeForce GT 340 1GB, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 3024 (69%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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