GeForce GTX 1070 Ti vs Radeon HD 5970

Intro

Compare all that to the Radeon HD 5970, which features a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also features 1600 Stream Processors, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070 Ti		180 Watts
Radeon HD 5970		294 Watts
	Difference: 114 Watts (63%)

Memory Bandwidth

In theory, the GeForce GTX 1070 Ti should be 2% faster than the Radeon HD 5970 overall, because of its higher data rate. (explain)

GeForce GTX 1070 Ti		262144 MB/sec
Radeon HD 5970		256000 MB/sec
	Difference: 6144 (2%)

Texel Rate

The GeForce GTX 1070 Ti should be a little bit (more or less 5%) more effective at texture filtering than the Radeon HD 5970. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
Radeon HD 5970		232000 Mtexels/sec
	Difference: 12264 (5%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1070 Ti is the winner, but only just. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
Radeon HD 5970		92800 Mpixels/sec
	Difference: 10048 (11%)

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 data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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