GeForce GT 340 1GB vs GeForce GTX 965M

Intro

Compare those specs to the GeForce GTX 965M, which uses a 28 nm design. nVidia has set the core speed at 944 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular card. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 965M is the winner, and very much so. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 25808 (587%)

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 (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
