Radeon HD 4730 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which has core speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 4730 should be quite a bit faster than the Radeon R9 M375 in general. (explain)

Radeon HD 4730		57600 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 22400 (64%)

Texel Rate

The Radeon R9 M375 will be quite a bit (more or less 81%) faster with regards to anisotropic filtering than the Radeon HD 4730. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 18200 (81%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is a better choice, by a large margin. (explain)

Radeon R9 M375		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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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