GeForce GT 310 vs GeForce GT 340 1GB

Intro

Compare those specifications to the GeForce GT 340 1GB, which has a GPU core clock speed of 550 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.

GeForce GT 310		16000 MB/sec
	Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 1GB should be quite a bit (about 274%) better at texture filtering than the GeForce GT 310. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 12888 (274%)

Pixel Rate

The GeForce GT 340 1GB is a lot (more or less 87%) more effective at full screen anti-aliasing than the GeForce GT 310, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GT 340 1GB		4400 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 2044 (87%)

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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
