Radeon HD 5770 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which features a GPU core 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 made up of 320 Stream Processors, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5770 should in theory be quite a bit better than the Radeon R5 M230 overall. (explain)

Radeon HD 5770		76800 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 60800 (380%)

Texel Rate

The Radeon HD 5770 should be a lot (approximately 118%) faster with regards to anisotropic filtering than the Radeon R5 M230. (explain)

Radeon HD 5770		34000 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 18400 (118%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 5770 is the winner, by far. (explain)

Radeon HD 5770		13600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 10480 (336%)

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 information (counted in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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