GeForce GT 340 1GB vs GeForce GTX 960M

Intro

Compare those specifications to the GeForce GTX 960M, which uses a 28 nm design. nVidia has set the core speed at 1096 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

	Difference: 4 Watts (6%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960M is 18% quicker than the GeForce GT 340 1GB in general, due to its higher data rate. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The GeForce GTX 960M is a lot (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, and very much so. (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 largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
