GeForce GT 340 vs Geforce GTX 760

Intro

Compare all of that to the Geforce GTX 760, which has GPU clock speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is comprised of 1152 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
Geforce GTX 760		170 Watts
	Difference: 101 Watts (146%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 should be 253% quicker than the GeForce GT 340 overall, due to its greater bandwidth. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 137856 (253%)

Texel Rate

The Geforce GTX 760 is quite a bit (about 435%) more effective at AF than the GeForce GT 340. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 76480 (435%)

Pixel Rate

The Geforce GTX 760 will be a lot (approximately 613%) faster with regards to anti-aliasing than the GeForce GT 340, and also able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 26960 (613%)

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 maximum amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
