Radeon HD 5750 512MB vs Radeon R9 M290X

Intro

Compare all of that to the Radeon R9 M290X, which makes use of a 28 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this card. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M290X is superior to the Radeon HD 5750 512MB, and very much so. (explain)

Radeon R9 M290X		27200 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 16000 (143%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
