AMD Radeon R9 290X
The AMD Radeon R9 290X is a high-end single-GPU graphics card for desktop PCs, that has been presented in October 2013. It is based on the "Hawaii" GPU and manufactured in 28 nanometers. The card offers 2816 shader units and a 512-bit memory interface (4 GB GDDR5, 320 GB/s at 5000 MHz).
The Hawaii chip is based on a slightly revised version of the GCN architecture. Among other things, the front-end has been doubled and optimized, size and speed of the L2 cache increased and the memory interface widened. Furthermore, the R9 290X offers more shaders (2816), TMUs (176) and ROPs (64) than the previous top model Radeon HD 7970. In addition to the higher performance, the 290X supports new features like DirectX 12 (FL 12_0).
Depending on game and settings, the performance of the Radeon R9 290X is similar to the Nvidia GeForce GTX Titan. Therefore, even the fastest mobile GPUs like the GeForce GTX 780M are outperformed by about 50 percent. Demanding games like Metro: Last Light can be played fluently in 2560 x 1600 pixels and maximum settings. In some cases, even the UltraHD resolution of 3840 x 2160 (4K) is possible.
The R9 290X supports well-known features like Eyefinity, but also some innovations such as True Audio and a new turbo mode. Depending on power consumption and temperature, the core can be boosted up to 1000 MHz. However, there is no offical base clock respectively a lower limit.
Thanks to dynamic clock adjustments and the Zero Core technology, the R9 290X is very energy efficient while idle. Under load, the card is rated at a typical power consumption of 250 watts.
