Radeon HD 4550 512MB vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which features a clock frequency of 1125 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M360 should perform a lot faster than the Radeon HD 4550 512MB in general. (explain)

Radeon R7 M360		16000 MB/sec
Radeon HD 4550 512MB		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R7 M360 should be quite a bit (more or less 463%) faster with regards to texture filtering than the Radeon HD 4550 512MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 22200 (463%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M360 is a better choice, by far. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 6600 (275%)

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 data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
