GeForce GT 340 1GB vs GeForce GTX 650 Ti

Intro

Compare that to the GeForce GTX 650 Ti, which has clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 41 Watts (59%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti should be 59% quicker than the GeForce GT 340 1GB in general, due to its greater bandwidth. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 32000 (59%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (approximately 237%) better at AF than the GeForce GT 340 1GB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 41792 (237%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is superior to the GeForce GT 340 1GB, and very much so. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 10448 (237%)

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 MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
