Radeon HD 5550 vs Radeon R7 M265

Intro

Compare those specs to the Radeon R7 M265, which features a GPU core clock speed of 725 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should perform quite a bit faster than the Radeon HD 5550 in general. (explain)

Radeon R7 M265		32000 MB/sec
Radeon HD 5550		12800 MB/sec
	Difference: 19200 (150%)

Texel Rate

The Radeon R7 M265 will be quite a bit (about 98%) more effective at texture filtering than the Radeon HD 5550. (explain)

Radeon R7 M265		17400 Mtexels/sec
Radeon HD 5550		8800 Mtexels/sec
	Difference: 8600 (98%)

Pixel Rate

The Radeon R7 M265 is much (approximately 32%) faster with regards to FSAA than the Radeon HD 5550, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 M265		5800 Mpixels/sec
Radeon HD 5550		4400 Mpixels/sec
	Difference: 1400 (32%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one 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. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
