GeForce GT 420 vs GeForce GTX 1060

Intro

Compare all that to the GeForce GTX 1060, which makes use of a 16 nm design. nVidia has set the core speed at 1506 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this card. It features 1280 SPUs as well as 80 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 420		50 Watts
GeForce GTX 1060		120 Watts
	Difference: 70 Watts (140%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1060 should be 583% quicker than the GeForce GT 420 in general, due to its higher bandwidth. (explain)

GeForce GTX 1060		196608 MB/sec
GeForce GT 420		28800 MB/sec
	Difference: 167808 (583%)

Texel Rate

The GeForce GTX 1060 should be much (about 2051%) better at texture filtering than the GeForce GT 420. (explain)

GeForce GTX 1060		120480 Mtexels/sec
GeForce GT 420		5600 Mtexels/sec
	Difference: 114880 (2051%)

Pixel Rate

The GeForce GTX 1060 will be quite a bit (more or less 2482%) faster with regards to full screen anti-aliasing than the GeForce GT 420, and able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1060		72288 Mpixels/sec
GeForce GT 420		2800 Mpixels/sec
	Difference: 69488 (2482%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 max fill rate.
