GeForce GT 340 vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has set the core frequency at 837 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this specific card. It features 2688 SPUs as well as 224 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX Titan should in theory perform quite a bit faster than the GeForce GT 340 in general. (explain)

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

Texel Rate

The GeForce GTX Titan will be much (about 965%) faster with regards to texture filtering than the GeForce GT 340. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan is the winner, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GT 340		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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video 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 number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
