Radeon HD 3650 vs Radeon R5 M230

Intro

Compare all of that to the Radeon R5 M230, which has a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is made up of 320 SPUs, 20 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3650 should be quite a bit faster than the Radeon R5 M230 overall. (explain)

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

Texel Rate

The Radeon R5 M230 should be quite a bit (approximately 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

If using high levels of AA is important to you, then the Radeon R5 M230 is superior to the Radeon HD 3650, but only just. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 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 this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
