GeForce GTX 1060 3GB vs Radeon HD 4870 X2

Intro

The GeForce GTX 1060 3GB has a GPU clock speed of 1506 MHz, and the 3072 MB of GDDR5 RAM runs at 2000 MHz through a 192-bit bus. It also is made up of 1152 Stream Processors, 72 TAUs, and 48 ROPs.

Compare all of that to the Radeon HD 4870 X2, which features a clock frequency of 750 MHz and a GDDR5 memory speed of 900 MHz. It also features a 256-bit bus, and uses a 55 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Radeon HD 4870 X2 350 Watts
Difference: 230 Watts (192%)

Memory Bandwidth

In theory, the Radeon HD 4870 X2 will be 17% faster than the GeForce GTX 1060 3GB overall, due to its higher data rate. (explain)

Radeon HD 4870 X2 230400 MB/sec
GeForce GTX 1060 3GB 196608 MB/sec
Difference: 33792 (17%)

Texel Rate

The GeForce GTX 1060 3GB will be a lot (more or less 81%) more effective at anisotropic filtering 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 should be quite a bit (approximately 201%) faster with regards to FSAA than the Radeon HD 4870 X2, and also able to handle 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 are applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
