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.
