CALIFORNIA: An American worldwide semiconductor company, AMD plans to officially introduce its new Radeon R9 300-series graphics processors in June, around the Computex Taipei 2015 trade-show. According to sources with knowledge of AMD plans, this time the company will take a rather untraditional approach to introduction. Instead of unveiling numerous new graphics cards one after another, the company is going to reveal the whole family at once. As reported, the new series will contain both new and old graphics processing units.
Based on media reports and sources with knowledge of AMD’s plans, it is expected that the Radeon R9 300-series family will contain three all new graphics processors: Fiji, Grenada (improved Hawaii) and Trinidad. In addition, some forecast that AMD to finally use Tonga XT chip with all compute units/stream processors activated.
Here is the compilation of what we do know about the Radeon R9 300-series range so far (please keep in mind that not all model numbers and specifications may be accurate):
AMD Radeon R9 390/390X – Fiji Pro/Fiji XT graphics processing units featuring GCN 1.3 architecture with up to 4096 stream processors and 4096-bit interface to HBM memory. Price range: $649 and upwards.
AMD Radeon R9 380/380X – Grenada Pro/Grenada XT graphics processing units featuring GCN 1.2 or GCN 1.3 architecture with up to 2816 stream processors and 512-bit interface to GDDR5 memory. Price range: $249 – $299 – $329. Since “Grenada” GPU is basically a revamped “Hawaii”, it is possible that instead of making a new GPU, AMD will simply use the old one under a new moniker.
AMD Radeon R9 375X – Tonga XT graphics processing units featuring GCN 1.2 architecture with up to 2048 stream processors and 384-bit interface to GDDR5 memory. Price range: around $229.
AMD Radeon R9 375 – Tonga Pro graphics processing units featuring GCN 1.2 architecture with up to 1792 stream processors and 256-bit interface to GDDR5 memory. Price range: around $199.
AMD Radeon R9 370/370X – Trinidad Pro/Trinidad XT graphics processing units featuring GCN 1.3 architecture with up to 1536 stream processors and 256-bit interface to GDDR5 memory. Price range: $119 – $149.
The situation with the upcoming Radeon R7 300-series look less clear. On the one hand, AMD could continue offering its code-named “Curacao” graphics processing units for Radeon R7 360-series graphics cards, but the company could also introduce something powered by the GCN 1.2 or the GCN 1.3 for the price range of around $100.
