GeForce GTX 1060 3GB vs Radeon HD 4870 X2

Intro

Compare all of that to the Radeon HD 4870 X2, which features GPU core speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

The GeForce GTX 1060 3GB is a lot (about 81%) better at AF than the Radeon HD 4870 X2. (explain)

GeForce GTX 1060 3GB		108432 Mtexels/sec
Radeon HD 4870 X2		60000 Mtexels/sec
	Difference: 48432 (81%)

Pixel Rate

The GeForce GTX 1060 3GB will be quite a bit (approximately 201%) better at full screen anti-aliasing than the Radeon HD 4870 X2, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1060 3GB		72288 Mpixels/sec
Radeon HD 4870 X2		24000 Mpixels/sec
	Difference: 48288 (201%)

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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
