AMD Hawaii’s GPU architecture has been presented and described in detail at the GPU ’14 press conference to date. The Hawaii GPU architecture is based on the latest GCN 2.0 (Graphics Core Next) architecture and has been redesigned from the ground up to enable the next era of gaming performance.
Next Generation AMD Hawaii GPU Architecture Revealed
The AMD Hawaii GPU architecture is integrated on the premium Radeon R9 290X graphics card from AMD, which is now the fastest graphics card in the world. AMD has made some very big changes with the new Hawaii architecture, including the addition of a massive 512-bit bus interface and a stream processor count of up to 2816 SPs on a 28nm chip that is just under 420mm2 in size, the Tahiti merged with the Radeon HD 7970 while being 30% smaller than NVIDIA’s flagship GK110 GPU.
There are two cards based on the Hawaii GPU architecture: the AMD Radeon R9 290X with the Hawaii XT core and the AMD Radeon R9 290 with the Hawaii Pro core. The specifications for the Hawaii XT part have been confirmed, but the exact configuration of the Hawaii Pro remains a mystery. Even so, the Hawaii GPU has more than 6 billion transistors compared to 4.3 billion transistors in the Radeon HD 7970. This is a phenomenal increase considering the price of the Hawaii GPU, which is $ 599 for the Radeon R9 290X. Dollar amounts.
The exact memory speeds and clock frequencies are currently unknown, but AMD showed a slide that stated the bandwidth for Hawaii was over 300 GB / s compared to 288 GB / s on the Radeon HD 7970 Tahiti. The AMD Hawaii GPU offers a total of 5 TFlops of computing power and supports the DirectX 11.2 range of functions.
