Radeon HD 5770 vs Radeon R9 M370X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5770 should in theory be a little bit superior to the Radeon R9 M370X overall. (explain)

Radeon HD 5770		76800 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 4800 (7%)

Texel Rate

The Radeon HD 5770 should be a bit (approximately 6%) more effective at anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon HD 5770		34000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 2000 (6%)

Pixel Rate

The Radeon HD 5770 will be a small bit (more or less 6%) faster with regards to anti-aliasing than the Radeon R9 M370X, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 5770		13600 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 800 (6%)

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 information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
