Radeon R9 290 vs Radeon R9 290X

Intro

The Radeon R9 290 makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this particular card. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon R9 290X, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this particular model. It features 2816 SPUs as well as 176 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The Radeon R9 290X will be just a bit (approximately 10%) faster with regards to AF 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 exactly the same pixel rate, so theoretically they should be equally good at at FSAA, and be capable of handling the same screen 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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum 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.
