Radeon HD 6770 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 6770 should theoretically be a small bit better than the Radeon R7 M260X overall. (explain)

Radeon HD 6770		67200 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 3200 (5%)

Texel Rate

The Radeon HD 6770 should be much (approximately 82%) faster with regards to AF than the Radeon R7 M260X. (explain)

Radeon HD 6770		36000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 16200 (82%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6770 is a better choice, by a large margin. (explain)

Radeon HD 6770		14400 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 7800 (118%)

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 largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
