Radeon R5 M255 vs Radeon R7 M360

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon R7 M360 should be quite a bit (approximately 44%) more effective at texture filtering than the Radeon R5 M255. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 8200 (44%)

Pixel Rate

The Radeon R7 M360 will be a little bit (approximately 20%) better at AA than the Radeon R5 M255, and also will be able to handle higher screen resolutions better. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon R5 M255		7520 Mpixels/sec
	Difference: 1480 (20%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
