GeForce 830M vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which comes with core clock speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 4 Rasterization Operator Units.

Radeon R5 M230		15600 Mtexels/sec
	Difference: 864 (6%)

Pixel Rate

The GeForce 830M is a lot (approximately 164%) better at AA than the Radeon R5 M230, and also able to handle higher screen resolutions better. (explain)

GeForce 830M		8232 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 5112 (164%)

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 (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video 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 maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
