GeForce GT 450 (OEM) vs GeForce GTX 960M

Intro

The GeForce GT 450 (OEM) has a clock frequency of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Compare that to the GeForce GTX 960M, which makes use of a 28 nm design. nVidia has set the core frequency at 1096 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GT 450 (OEM) 96000 MB/sec
GeForce GTX 960M 64000 MB/sec
Difference: 32000 (50%)

Texel Rate

The GeForce GTX 960M should be much (approximately 131%) faster with regards to anisotropic filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 960M 43840 Mtexels/sec
GeForce GT 450 (OEM) 18960 Mtexels/sec
Difference: 24880 (131%)

Pixel Rate

The GeForce GT 450 (OEM) will be just a bit (more or less 8%) better at FSAA than the GeForce GTX 960M, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GT 450 (OEM) 18960 Mpixels/sec
GeForce GTX 960M 17536 Mpixels/sec
Difference: 1424 (8%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
