GeForce GTX Titan X vs Radeon HD 3850 X2

Intro

Compare all that to the Radeon HD 3850 X2, which features a core clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Texel Rate

The GeForce GTX Titan X is much (more or less 798%) faster with regards to AF than the Radeon HD 3850 X2. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon HD 3850 X2		21376 Mtexels/sec
	Difference: 170624 (798%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan X is superior to the Radeon HD 3850 X2, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon HD 3850 X2		21376 Mpixels/sec
	Difference: 74624 (349%)

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 (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number 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 the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
