Radeon HD 3850 256MB vs Radeon R7 M260X

Intro

The Radeon HD 3850 256MB makes use of a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory runs at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Compare that to the Radeon R7 M260X, which comes with a core clock speed of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Theoretically speaking, the Radeon R7 M260X is 21% faster than the Radeon HD 3850 256MB overall, because of its higher bandwidth. (explain)

Radeon R7 M260X 64000 MB/sec
Radeon HD 3850 256MB 52992 MB/sec
Difference: 11008 (21%)

Texel Rate

The Radeon R7 M260X should be much (more or less 85%) more effective at AF than the Radeon HD 3850 256MB. (explain)

Radeon R7 M260X 19800 Mtexels/sec
Radeon HD 3850 256MB 10688 Mtexels/sec
Difference: 9112 (85%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 3850 256MB is the winner, by far. (explain)

Radeon HD 3850 256MB 10688 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 4088 (62%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
