Radeon HD 3650 512MB vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which uses a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 3650 512MB should perform much faster than the Radeon R7 M260 overall. (explain)

Radeon HD 3650 512MB		25600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 9600 (60%)

Texel Rate

The Radeon R7 M260 should be quite a bit (more or less 196%) better at anisotropic filtering than the Radeon HD 3650 512MB. (explain)

Radeon R7 M260		17160 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 11360 (196%)

Pixel Rate

The Radeon R7 M260 should be quite a bit (more or less 97%) better at full screen anti-aliasing than the Radeon HD 3650 512MB, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 M260		5720 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 2820 (97%)

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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
