Radeon HD 3650 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which uses a 28 nm design. AMD has set the core frequency at 780 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 320 SPUs as well as 20 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 3650 will be 60% quicker than the Radeon R5 M230 in general, due to its higher bandwidth. (explain)

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

Texel Rate

The Radeon R5 M230 is quite a bit (about 169%) more effective at texture filtering than the Radeon HD 3650. (explain)

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

Pixel Rate

The Radeon R5 M230 should be a little bit (more or less 8%) more effective at AA than the Radeon HD 3650, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon R5 M230		3120 Mpixels/sec
Radeon HD 3650		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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
