Radeon R5 M230 vs Radeon R7 370 4G

Intro

Compare those specifications to the Radeon R7 370 4G, which makes use of a 28 nm design. AMD has set the core speed at 975 MHz. The GDDR5 memory runs at a speed of 1400 MHz on this specific card. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 370 4G should perform a lot faster than the Radeon R5 M230 overall. (explain)

Radeon R7 370 4G		179200 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 163200 (1020%)

Texel Rate

The Radeon R7 370 4G will be a lot (about 300%) more effective at texture filtering than the Radeon R5 M230. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 46800 (300%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 370 4G is superior to the Radeon R5 M230, and very much so. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 28080 (900%)

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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
