Radeon HD 6750 vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M380 should theoretically be much better than the Radeon HD 6750 in general. (explain)

Radeon R9 M380		96000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 32000 (50%)

Texel Rate

The Radeon R9 M380 should be much (about 53%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 13900 (53%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M380 is a better choice, by far. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 4400 (38%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
