GeForce 830M vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which has core clock speeds of 780 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M230 should be a little bit faster than the GeForce 830M overall. (explain)

Radeon R5 M230		16000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 830M will be just a bit (approximately 6%) better at anisotropic filtering than the Radeon R5 M230. (explain)

GeForce 830M		16464 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 864 (6%)

Pixel Rate

The GeForce 830M will be much (more or less 164%) faster with regards to AA than the Radeon R5 M230, and also should be capable of handling higher resolutions while still performing well. (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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
