GeForce 9800 GTX vs Radeon R5 M230

Intro

Compare those specs to the Radeon R5 M230, which makes use of a 28 nm design. AMD has set the core frequency at 780 MHz. The DDR3 memory runs at a speed of 1000 MHz on this card. It features 320 SPUs along with 20 Texture Address Units and 4 Rasterization Operator Units.

Radeon R5 M230		16000 MB/sec
	Difference: 54400 (340%)

Texel Rate

The GeForce 9800 GTX is quite a bit (approximately 177%) faster with regards to texture filtering than the Radeon R5 M230. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 27600 (177%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9800 GTX is the winner, by a large margin. (explain)

GeForce 9800 GTX		10800 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 7680 (246%)

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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This 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 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
