Radeon HD 3650 256MB vs Radeon R5 M230

Intro

Compare that to the Radeon R5 M230, which uses a 28 nm design. AMD has set the core speed at 780 MHz. The DDR3 memory is set to run at a speed of 1000 MHz on this specific model. It features 320 SPUs as well as 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 3650 256MB should be quite a bit faster than the Radeon R5 M230 overall. (explain)

Radeon HD 3650 256MB		25600 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 9600 (60%)

Texel Rate

The Radeon R5 M230 should be quite a bit (more or less 169%) more effective at AF than the Radeon HD 3650 256MB. (explain)

Radeon R5 M230		15600 Mtexels/sec
Radeon HD 3650 256MB		5800 Mtexels/sec
	Difference: 9800 (169%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R5 M230 is superior to the Radeon HD 3650 256MB, but it probably won't make a huge difference. (explain)

Radeon R5 M230		3120 Mpixels/sec
Radeon HD 3650 256MB		2900 Mpixels/sec
	Difference: 220 (8%)

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 (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
