GeForce 9800 GT 1GB vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which has GPU clock speed of 780 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also is comprised of 320 SPUs, 20 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GT 1GB should perform a lot faster than the Radeon R5 M230 in general. (explain)

GeForce 9800 GT 1GB		57600 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The GeForce 9800 GT 1GB will be quite a bit (more or less 115%) faster with regards to anisotropic filtering than the Radeon R5 M230. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 18000 (115%)

Pixel Rate

The GeForce 9800 GT 1GB is much (about 208%) more effective at full screen anti-aliasing than the Radeon R5 M230, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 6480 (208%)

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 one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
