GeForce GT 210 vs GeForce GT 340

Intro

Compare those specs to the GeForce GT 340, which uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this specific model. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 340		69 Watts
	Difference: 38 Watts (123%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 should be 325% faster than the GeForce GT 210 in general, because of its greater data rate. (explain)

GeForce GT 340		54400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 41600 (325%)

Texel Rate

The GeForce GT 340 should be much (approximately 274%) better at texture filtering than the GeForce GT 210. (explain)

GeForce GT 340		17600 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 12888 (274%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 340 is superior to the GeForce GT 210, and very much so. (explain)

GeForce GT 340		4400 Mpixels/sec
GeForce GT 210		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 (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
