GeForce GTX 1060 vs Radeon HD 4870 X2

Intro

Compare those specifications to the Radeon HD 4870 X2, which features core speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1060		120 Watts
Radeon HD 4870 X2		350 Watts
	Difference: 230 Watts (192%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4870 X2 is 17% quicker than the GeForce GTX 1060 overall, because of its higher bandwidth. (explain)

Radeon HD 4870 X2		230400 MB/sec
GeForce GTX 1060		196608 MB/sec
	Difference: 33792 (17%)

Texel Rate

The GeForce GTX 1060 is quite a bit (about 101%) better at texture filtering than the Radeon HD 4870 X2. (explain)

GeForce GTX 1060		120480 Mtexels/sec
Radeon HD 4870 X2		60000 Mtexels/sec
	Difference: 60480 (101%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1060 is a better choice, by far. (explain)

GeForce GTX 1060		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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many 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.
