GeForce GTX 1070 Ti vs Radeon HD 5970

Intro

Compare that to the Radeon HD 5970, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular card. It features 1600 SPUs along with 160 Texture Address Units and 64 ROPs.

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

As far as performance goes, the GeForce GTX 1070 Ti should theoretically be just a bit superior to the Radeon HD 5970 in general. (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%) faster with regards to 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 running with high levels of AA is important to you, then the GeForce GTX 1070 Ti is a better choice, 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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 applied per second. This number is calculated by multiplying the total amount of 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
