Radeon R5 M255 vs Radeon R7 M360

Intro

Compare all of that to the Radeon R7 M360, which has a core clock frequency of 1125 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 M360 should be a lot (more or less 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 just a bit (about 20%) faster with regards to FSAA than the Radeon R5 M255, and also capable of handling higher resolutions without slowing down too much. (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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
