GeForce 930M vs GeForce GT 340

Intro

Compare all of that to the GeForce GT 340, which comes with a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 340 is 278% quicker than the GeForce 930M overall, because of its higher data rate. (explain)

GeForce GT 340		54400 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The GeForce 930M should be quite a bit (more or less 27%) better at anisotropic filtering than the GeForce GT 340. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce 930M is a better choice, by far. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 340		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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better 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 record to its local memory in a second - measured in millions of pixels per second. The number 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
