Radeon HD 6450 (OEM) vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 memory runs at a speed of 1100 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375 is 175% faster than the Radeon HD 6450 (OEM) in general, because of its greater bandwidth. (explain)

Radeon R9 M375		35200 MB/sec
Radeon HD 6450 (OEM)		12800 MB/sec
	Difference: 22400 (175%)

Texel Rate

The Radeon R9 M375 is much (about 712%) faster with regards to AF than the Radeon HD 6450 (OEM). (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 35600 (712%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375 is superior to the Radeon HD 6450 (OEM), and very much so. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 13740 (550%)

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 max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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