GeForce 9800 GT 1GB vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which comes with core 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.

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

Pixel Rate

The GeForce 9800 GT 1GB will be much (approximately 208%) faster with regards to anti-aliasing than the Radeon R5 M230, and should be able to handle higher resolutions while still performing well. (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 information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
