GeForce GT 450 (OEM) vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which uses a 28 nm design. nVidia has set the core frequency at 1127 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific card. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 960		120 Watts
	Difference: 14 Watts (13%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960 is 17% faster than the GeForce GT 450 (OEM) in general, due to its greater data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The GeForce GTX 960 is quite a bit (approximately 280%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 53168 (280%)

Pixel Rate

The GeForce GTX 960 should be quite a bit (about 90%) faster with regards to AA than the GeForce GT 450 (OEM), and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 17104 (90%)

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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
