GeForce GTX 1060 vs Radeon HD 4850 X2 1GB

Intro

Compare all that to the Radeon HD 4850 X2 1GB, which features a core clock speed of 625 MHz and a GDDR3 memory speed of 993 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 4850 X2 1GB		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

Performance-wise, the GeForce GTX 1060 should theoretically be much better than the Radeon HD 4850 X2 1GB in general. (explain)

GeForce GTX 1060		196608 MB/sec
Radeon HD 4850 X2 1GB		127104 MB/sec
	Difference: 69504 (55%)

Texel Rate

The GeForce GTX 1060 will be a lot (more or less 141%) faster with regards to anisotropic filtering than the Radeon HD 4850 X2 1GB. (explain)

GeForce GTX 1060		120480 Mtexels/sec
Radeon HD 4850 X2 1GB		50000 Mtexels/sec
	Difference: 70480 (141%)

Pixel Rate

The GeForce GTX 1060 will be quite a bit (approximately 261%) more effective at AA than the Radeon HD 4850 X2 1GB, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1060		72288 Mpixels/sec
Radeon HD 4850 X2 1GB		20000 Mpixels/sec
	Difference: 52288 (261%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, 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 in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
