The dual-GPU AMD Radeon HD 8990 is rumored to be released in the second quarter of 2013. This is according to information obtained by the Spanish website, Bit Dreams. They also claimed to have information on the performance and specifications of the AMD Radeon HD 8000 series GPUs.
We have reported on the possible existence of the Sea Island GPUs in June this year, and according to the alleged leaked information obtained by Bit Dreams, the specifications of the Sea Island GPUs are in line with our expectations. Bit Dreams also claimed that the top end dual-GPU AMD HD 8990 is slated for launch in the second quarter of next year. This card will essentially be two AMD Radeon HD 8970 GPUs combined on a single PCB.
This graphics card is listed as having 5.1 billion transistors, between the two GPUs; it will feature 5,210 stream processors and 160 texture units per core. The card is also alleged to support video memory capacity in the range of 6GB to 12GB and will be clocked at a factory default of 1,250MHz. Each of its 8970 GPU will be rated at 950MHz and has 48 ROP units. As a note to our readers, the single AMD Radeon HD 8970 GPU is alleged to have a default clock speed of 1,050MHz core and feature video memory rated at 1,500MHz. This means that each graphic core of the AMD Radeon HD 8990 card is actually set lower than a standalone 8970 GPU.
The card will support DirectX 11, Shader Model 5.0 and OpenGL 4.2, like the rest of the AMD Radeon HD 8000 Series GPUs. We do hope to witness the official launch of this dual-GPU card next year; however, given the elusiveness of the official Radeon HD 7990 card, we may get to see similar efforts by partner graphics cards manufacturers as they take matters into their own hands.
