Radeon R5 M255 vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which features GPU core speed of 1125 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 M360 should be much (approximately 44%) better 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 (more or less 20%) faster with regards to AA than the Radeon R5 M255, and also will be capable of handling higher resolutions while still performing well. (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 maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
