GeForce GT 340 vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which comes with core speeds of 1127 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

GeForce GT 340		17600 Mtexels/sec
	Difference: 54528 (310%)

Pixel Rate

The GeForce GTX 960 will be quite a bit (more or less 720%) faster with regards to anti-aliasing than the GeForce GT 340, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 31664 (720%)

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 (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core 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 maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
