GeForce GTX 970M vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which features a core clock frequency 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 made up of 320 SPUs, 20 TAUs, and 4 ROPs.

Texel Rate

The GeForce GTX 970M will be quite a bit (about 374%) better at anisotropic filtering than the Radeon R5 M230. (explain)

GeForce GTX 970M		73920 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 58320 (374%)

Pixel Rate

The GeForce GTX 970M should be a lot (more or less 1322%) better at AA than the Radeon R5 M230, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 970M		44352 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 41232 (1322%)

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 largest amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it 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 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 worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
