Radeon HD 3650 vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which has a clock frequency of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M265 should theoretically be a lot superior to the Radeon HD 3650 in general. (explain)

Radeon R7 M265		32000 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The Radeon R7 M265 will be a lot (about 200%) faster with regards to AF than the Radeon HD 3650. (explain)

Radeon R7 M265		17400 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 11600 (200%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 M265 is superior to the Radeon HD 3650, and very much so. (explain)

Radeon R7 M265		5800 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 2900 (100%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
