GeForce GT 340 1GB vs GeForce GTX Titan

Intro

Compare that to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has clocked the core speed at 837 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this specific model. It features 2688 SPUs as well as 224 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340 1GB		69 Watts
GeForce GTX Titan		250 Watts
	Difference: 181 Watts (262%)

Memory Bandwidth

Performance-wise, the GeForce GTX Titan should theoretically be much better than the GeForce GT 340 1GB overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 233984 (430%)

Texel Rate

The GeForce GTX Titan should be quite a bit (more or less 965%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 169888 (965%)

Pixel Rate

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

GeForce GTX Titan		40176 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 35776 (813%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 can 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 Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
