GeForce GT 130 vs GeForce GT 340

Intro

Compare all that to the GeForce GT 340, which uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce GT 130		75 Watts
	Difference: 6 Watts (9%)

Memory Bandwidth

In theory, the GeForce GT 340 is 353% quicker than the GeForce GT 130 in general, because of its greater data rate. (explain)

GeForce GT 340		54400 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 42400 (353%)

Texel Rate

The GeForce GT 340 will be quite a bit (about 47%) more effective at AF than the GeForce GT 130. (explain)

GeForce GT 340		17600 Mtexels/sec
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 superior to the GeForce GT 340, by a large margin. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce GT 340		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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount 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 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
