GeForce GT 340 1GB vs GeForce GTX 965M

Intro

The GeForce GT 340 1GB comes with a GPU core speed of 550 MHz, and the 1024 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 TAUs, and 8 ROPs.

Compare all of that to the GeForce GTX 965M, which has a GPU core clock speed of 944 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 that the graphics card can 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
