Radeon R9 M365X vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon R9 M365X is a small bit (about 16%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 5000 (16%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M365X is superior to the Radeon R9 M370X, but only just. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 2000 (16%)

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.

Price Comparison

Specifications

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
