GeForce 8800 GT 1GB vs GeForce GT 340

Intro

Compare all of that to the GeForce GT 340, which features a core clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce 8800 GT 1GB		105 Watts
	Difference: 36 Watts (52%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GT 1GB should perform a bit faster than the GeForce GT 340 overall. (explain)

GeForce 8800 GT 1GB		57600 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 3200 (6%)

Texel Rate

The GeForce 8800 GT 1GB should be quite a bit (approximately 91%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 16000 (91%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 8800 GT 1GB is superior to the GeForce GT 340, and very much so. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 5200 (118%)

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 (in units of MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
