Radeon R5 M255 vs Radeon R7 M360

Intro

Compare all of that to the Radeon R7 M360, which uses a 28 nm design. AMD has clocked the core speed at 1125 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this card. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon R7 M360 is much (more or less 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 should be just a bit (more or less 20%) faster with regards to FSAA than the Radeon R5 M255, and also should be capable of handling higher resolutions more effectively. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
