Radeon HD 3650 512MB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which features GPU clock speed of 1015 MHz, and 4096 MB of DDR3 RAM running at 1100 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375 should in theory be a lot better than the Radeon HD 3650 512MB in general. (explain)

Radeon R9 M375		35200 MB/sec
Radeon HD 3650 512MB		25600 MB/sec
	Difference: 9600 (38%)

Texel Rate

The Radeon R9 M375 is quite a bit (more or less 600%) better at AF than the Radeon HD 3650 512MB. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 34800 (600%)

Pixel Rate

The Radeon R9 M375 should be quite a bit (approximately 460%) more effective at full screen anti-aliasing than the Radeon HD 3650 512MB, and should be able to handle higher resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 13340 (460%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
