GeForce GTX 1070 Ti vs Radeon HD 3850 X2

Intro

Compare all of that to the Radeon HD 3850 X2, which uses a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 RAM is set to run at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 1070 Ti should be quite a bit faster than the Radeon HD 3850 X2 overall. (explain)

GeForce GTX 1070 Ti		262144 MB/sec
Radeon HD 3850 X2		105984 MB/sec
	Difference: 156160 (147%)

Texel Rate

The GeForce GTX 1070 Ti is a lot (approximately 1043%) faster with regards to AF than the Radeon HD 3850 X2. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
Radeon HD 3850 X2		21376 Mtexels/sec
	Difference: 222888 (1043%)

Pixel Rate

The GeForce GTX 1070 Ti should be a lot (about 381%) more effective at full screen anti-aliasing than the Radeon HD 3850 X2, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
Radeon HD 3850 X2		21376 Mpixels/sec
	Difference: 81472 (381%)

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 (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core 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 per second.

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