Radeon HD 6870 vs Radeon R9 M290X

Intro

The Radeon HD 6870 comes with a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 memory is set to run at 1050 MHz through a 256-bit bus. It also features 1120 SPUs, 56 TAUs, and 32 ROPs.

Compare all that to the Radeon R9 M290X, which features core speeds of 850 MHz on the GPU, and 1200 MHz on the 4096 MB of GDDR5 RAM. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Radeon R9 M290X 153600 MB/sec
Radeon HD 6870 134400 MB/sec
Difference: 19200 (14%)

Texel Rate

The Radeon R9 M290X is a lot (approximately 35%) better at anisotropic filtering than the Radeon HD 6870. (explain)

Radeon R9 M290X 68000 Mtexels/sec
Radeon HD 6870 50400 Mtexels/sec
Difference: 17600 (35%)

Pixel Rate

The Radeon HD 6870 is just a bit (approximately 6%) more effective at anti-aliasing than the Radeon R9 M290X, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 6870 28800 Mpixels/sec
Radeon R9 M290X 27200 Mpixels/sec
Difference: 1600 (6%)

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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
