GeForce GTX Titan X vs Radeon HD 5550

Intro

Compare all of that to the Radeon HD 5550, which comes with GPU clock speed of 550 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan X, in theory, should perform a lot faster than the Radeon HD 5550 overall. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 323200 (2525%)

Texel Rate

The GeForce GTX Titan X will be a lot (more or less 2082%) faster with regards to AF than the Radeon HD 5550. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 183200 (2082%)

Pixel Rate

The GeForce GTX Titan X should be a lot (more or less 2082%) faster with regards to full screen anti-aliasing than the Radeon HD 5550, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 91600 (2082%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
