GeForce GT 430 1GB vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which comes with a core clock speed of 780 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GT 430 1GB should perform a lot faster than the Radeon R5 M230 in general. (explain)

GeForce GT 430 1GB		28800 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The Radeon R5 M230 will be quite a bit (more or less 39%) better at anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 4400 (39%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R5 M230 is the winner, not by a very large margin though. (explain)

Radeon R5 M230		3120 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 320 (11%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
