Radeon HD 5750 1GB vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 1GB should in theory be a small bit superior to the Radeon R9 M370X overall. (explain)

Radeon HD 5750 1GB		73600 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M370X is quite a bit (about 27%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 6800 (27%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M370X is a better choice, though only just barely. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 1600 (14%)

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 maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
