Radeon R9 295X2 vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM works at a speed of 1500 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 295X2 should in theory be quite a bit faster than the Radeon R9 M380 in general. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 544000 (567%)

Texel Rate

The Radeon R9 295X2 will be a lot (about 796%) better at anisotropic filtering than the Radeon R9 M380. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 318336 (796%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 295X2 is superior to the Radeon R9 M380, and very much so. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 114304 (714%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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