GeForce GTX 1070 Ti vs Radeon HD 4870 X2

Intro

The GeForce GTX 1070 Ti makes use of a 16 nm design. nVidia has clocked the core speed at 1607 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this card. It features 2432 SPUs as well as 152 Texture Address Units and 64 ROPs.

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

Radeon HD 4870 X2 60000 Mtexels/sec
Difference: 184264 (307%)

Pixel Rate

The GeForce GTX 1070 Ti will be a lot (about 329%) faster with regards to full screen anti-aliasing than the Radeon HD 4870 X2, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 1070 Ti 102848 Mpixels/sec
Radeon HD 4870 X2 24000 Mpixels/sec
Difference: 78848 (329%)

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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
