GeForce 9800 GT 1GB vs Radeon R5 M230

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GT 1GB is 260% quicker than the Radeon R5 M230 in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 9800 GT 1GB is a lot (more or less 115%) more effective at AF 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 should be a lot (approximately 208%) faster with regards to FSAA than the Radeon R5 M230, and also able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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