Radeon HD 5770 vs Radeon R9 M365X

Intro

The Radeon HD 5770 has a clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon R9 M365X, which comes with clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5770 will be 7% faster than the Radeon R9 M365X overall, because of its greater bandwidth. (explain)

Radeon HD 5770 76800 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 4800 (7%)

Texel Rate

The Radeon R9 M365X should be a bit (approximately 9%) more effective at anisotropic filtering than the Radeon HD 5770. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 3000 (9%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M365X is a better choice, but not by far. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 1200 (9%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card 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 maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
