Radeon HD 5750 512MB vs Radeon R9 270X

Intro

Compare all of that to the Radeon R9 270X, which comes with a clock speed of 1000 MHz and a GDDR5 memory speed of 1400 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Theoretically speaking, the Radeon R9 270X should be a lot faster than the Radeon HD 5750 512MB in general. (explain)

Radeon R9 270X		179200 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 105600 (143%)

Texel Rate

The Radeon R9 270X is much (about 217%) more effective at AF than the Radeon HD 5750 512MB. (explain)

Radeon R9 270X		80000 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 54800 (217%)

Pixel Rate

The Radeon R9 270X should be quite a bit (more or less 186%) faster with regards to anti-aliasing than the Radeon HD 5750 512MB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 270X		32000 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 20800 (186%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 bandwidth is, the lower the potential to get to the max fill rate.
