GeForce GTX 285 1GB vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which comes with GPU core speed of 780 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Radeon R5 M230		15600 Mtexels/sec
	Difference: 36240 (232%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 285 1GB is superior to the Radeon R5 M230, and very much so. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 17616 (565%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock 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 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 maximum fill rate.
