Radeon HD 4730 vs Radeon R9 M375X

Intro

The Radeon HD 4730 features a GPU core clock speed of 700 MHz, and the 512 MB of GDDR5 memory runs at 900 MHz through a 128-bit bus. It also is made up of 640(128x5) Stream Processors, 32 TAUs, and 8 ROPs.

Compare those specs to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be quite a bit superior to the Radeon HD 4730 overall. (explain)

Radeon R9 M375X 72000 MB/sec
Radeon HD 4730 57600 MB/sec
Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X will be a lot (about 81%) more effective at anisotropic filtering than the Radeon HD 4730. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon HD 4730 22400 Mtexels/sec
Difference: 18200 (81%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375X is superior to the Radeon HD 4730, by far. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon HD 4730 5600 Mpixels/sec
Difference: 10640 (190%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
