GeForce GTX 280 vs Radeon R5 M230

Intro

Compare 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 memory. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 280, in theory, should be quite a bit faster than the Radeon R5 M230 in general. (explain)

GeForce GTX 280		141696 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 125696 (786%)

Texel Rate

The GeForce GTX 280 is a lot (approximately 209%) more effective at AF than the Radeon R5 M230. (explain)

GeForce GTX 280		48160 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 32560 (209%)

Pixel Rate

The GeForce GTX 280 should be much (about 517%) faster with regards to anti-aliasing than the Radeon R5 M230, and able to handle higher screen resolutions better. (explain)

GeForce GTX 280		19264 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 16144 (517%)

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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
