Radeon R7 360 vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which uses a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 360 should in theory perform much faster than the Radeon R9 M265X in general. (explain)

Radeon R7 360		104000 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 32000 (44%)

Texel Rate

The Radeon R7 360 will be quite a bit (more or less 119%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 27400 (119%)

Pixel Rate

The Radeon R7 360 is much (about 83%) more effective at FSAA than the Radeon R9 M265X, and will be capable of handling higher resolutions better. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 7600 (83%)

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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
