GeForce GT 450 (OEM) vs GeForce GTX 1060

Intro

Compare those specifications to the GeForce GTX 1060, which comes with GPU core speed of 1506 MHz, and 6144 MB of GDDR5 memory running at 2000 MHz through a 192-bit bus. It also is comprised of 1280 SPUs, 80 Texture Address Units, and 48 ROPs.

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 1060		120 Watts
	Difference: 14 Watts (13%)

Memory Bandwidth

In theory, the GeForce GTX 1060 should be 105% faster than the GeForce GT 450 (OEM) overall, because of its greater data rate. (explain)

GeForce GTX 1060		196608 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 100608 (105%)

Texel Rate

The GeForce GTX 1060 is much (approximately 535%) faster with regards to AF than the GeForce GT 450 (OEM). (explain)

GeForce GTX 1060		120480 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 101520 (535%)

Pixel Rate

The GeForce GTX 1060 will be much (more or less 281%) more effective at anti-aliasing than the GeForce GT 450 (OEM), and also will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1060		72288 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 53328 (281%)

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 information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
