Radeon R9 290 vs Radeon R9 290X

Intro

The Radeon R9 290 features a core clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 512-bit bus, and uses a 28 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon R9 290X, which has a clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 512-bit memory bus, and uses a 28 nm design. It features 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon R9 290X is just a bit (more or less 10%) better at anisotropic filtering than the Radeon R9 290. (explain)

Radeon R9 290X 140800 Mtexels/sec
Radeon R9 290 128000 Mtexels/sec
Difference: 12800 (10%)

Pixel Rate

Both cards have the exact same pixel fill rate, so theoretically they should perform equally good at at AA, and be able to handle the same resolutions. (explain)

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 (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

wow... they are practically EXACTLY the same LOLOLOL
...although these stats are wrong, core speed for the 290 is 940mhz and for the 290x is 1000mhz.
