GeForce GTX Titan X vs Radeon HD 5670

Intro

Compare those specs to the Radeon HD 5670, which uses a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this model. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5670		61 Watts
GeForce GTX Titan X		250 Watts
	Difference: 189 Watts (310%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan X is 425% faster than the Radeon HD 5670 overall, due to its greater data rate. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 272000 (425%)

Texel Rate

The GeForce GTX Titan X should be quite a bit (approximately 1139%) faster with regards to texture filtering than the Radeon HD 5670. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 176500 (1139%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is a better choice, by far. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 89800 (1448%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 output 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 max fill rate.
