GeForce GT 130 vs GeForce GT 340 1GB

Intro

Compare those specifications to the GeForce GT 340 1GB, which uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this specific model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

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

Texel Rate

The GeForce GT 340 1GB should be quite a bit (more or less 47%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 5600 (47%)

Pixel Rate

The GeForce GT 130 should be much (more or less 82%) better at AA than the GeForce GT 340 1GB, and also capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface 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 higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
