Boost) and 1500 MHz (6000 MHz effective) for the memory. Compared to the HD 7970, the R9 280X clocks slightly higher at 1050 MHz for the Core (max.
Tahiti is based on the GCN architecture and offers 2048 shaders, 128 TMUs and 32 ROPs. The R9 280X uses the same chip as the older Radeon HD 7970. The card offers 2048 shader units and a 384-bit memory interface (3 GB GDDR5, 288 GB/s). It is based on the "Tahiti" GPU and manufactured in 28 nanometers. The AMD Radeon R9 280X is a fast single-GPU graphics card for desktop PCs, that has been presented in October 2013. Under load, the card is rated at a typical power consumption of 250 watts.ĪMD Radeon R9 280X ► remove from comparison Thanks to dynamic clock adjustments and the Zero Core technology, the R9 290X is very energy efficient while idle. However, there is no offical base clock respectively a lower limit. Depending on power consumption and temperature, the core can be boosted up to 1000 MHz.
The R9 290X supports well-known features like Eyefinity, but also some innovations such as True Audio and a new turbo mode. In some cases, even the UltraHD resolution of 3840 x 2160 (4K) is possible. Demanding games like Metro: Last Light can be played fluently in 2560 x 1600 pixels and maximum settings. Therefore, even the fastest mobile GPUs like the GeForce GTX 780M are outperformed by about 50 percent. In addition to the higher performance, the 290X supports new features like DirectX 12 (FL 12_0).ĭepending on game and settings, the performance of the Radeon R9 290X is similar to the Nvidia GeForce GTX Titan. Furthermore, the R9 290X offers more shaders (2816), TMUs (176) and ROPs (64) than the previous top model Radeon HD 7970. Among other things, the front-end has been doubled and optimized, size and speed of the L2 cache increased and the memory interface widened. The Hawaii chip is based on a slightly revised version of the GCN architecture. The card offers 2816 shader units and a 512-bit memory interface (4 GB GDDR5, 320 GB/s at 5000 MHz). It is based on the "Hawaii" GPU and manufactured in 28 nanometers. The AMD Radeon R9 290X is a high-end single-GPU graphics card for desktop PCs, that has been presented in October 2013.
