Radeon R9 M295X vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which features a clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X should be 144% faster than the Radeon R9 M370X in general, due to its higher bandwidth. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 104000 (144%)

Texel Rate

The Radeon R9 M295X is a lot (more or less 200%) faster with regards to anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 64000 (200%)

Pixel Rate

The Radeon R9 M295X should be a lot (approximately 88%) more effective at full screen anti-aliasing than the Radeon R9 M370X, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 11200 (88%)

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 data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
