Radeon R9 M295X vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which features a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X will be 83% quicker than the Radeon R9 M385X in general, because of its greater bandwidth. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 80000 (83%)

Texel Rate

The Radeon R9 M295X should be quite a bit (about 56%) more effective at texture filtering than the Radeon R9 M385X. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 34400 (56%)

Pixel Rate

The Radeon R9 M295X is quite a bit (more or less 36%) better at full screen anti-aliasing than the Radeon R9 M385X, and also should be able to handle higher resolutions better. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 6400 (36%)

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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 processed in one second. This number is worked out by multiplying the total amount of 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
