GeForce GT 130 vs GeForce GT 340 1GB

Intro

Compare all of that to the GeForce GT 340 1GB, which features a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 32 Texture Address Units, and 8 ROPs.

GeForce GT 130		12000 Mtexels/sec
	Difference: 5600 (47%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 130 is a better choice, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 3600 (82%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. 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 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 reach the maximum fill rate.
