GeForce 9800 GTX+ vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which has GPU clock speed of 780 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 9800 GTX+ should be a lot faster than the Radeon R5 M230 overall. (explain)

GeForce 9800 GTX+		70400 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 54400 (340%)

Texel Rate

The GeForce 9800 GTX+ should be a lot (more or less 203%) better at anisotropic filtering than the Radeon R5 M230. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 31632 (203%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9800 GTX+ is a better choice, and very much so. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 8688 (278%)

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 (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
