GeForce GT 130 vs GeForce GT 340

Intro

Compare those specs to the GeForce GT 340, which features GPU core speed of 550 MHz, and 512 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also features 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

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 should be 353% quicker than the GeForce GT 130 overall, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GT 340 should be much (more or less 47%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

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

Pixel Rate

The GeForce GT 130 will be much (more or less 82%) more effective at full screen anti-aliasing than the GeForce GT 340, and also able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
