GeForce GT 340 1GB vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which uses a 28 nm design. nVidia has set the core speed at 1096 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Texel Rate

The GeForce GTX 960M will be quite a bit (more or less 149%) better at AF than the GeForce GT 340 1GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 26240 (149%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 960M is superior to the GeForce GT 340 1GB, by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 13136 (299%)

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 max amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
