Radeon R9 M265X vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon R9 M370X should be a lot (more or less 39%) better at AF than the Radeon R9 M265X. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 9000 (39%)

Pixel Rate

The Radeon R9 M370X should be much (about 39%) more effective at anti-aliasing than the Radeon R9 M265X, and also should be able to handle higher resolutions more effectively. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 3600 (39%)

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 (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure 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 graphics 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 most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
