Yesterday the news reached our forums that Sapphire is listing the entire Radeon 300 Series on their website, and that includes the R9 390X, R9 390, R9 380, R7 370 and R7 360. And hey, there are entries for two Fiji cards as well, the R9 Fury X and R9 Fury.
Sapphire is listing EVERYTHING, this is a pretty severe leak, here a short overview.
The high-end Radeon R9 390X Tri-X OC is the Grenada XT (Hawaii XT) GPU with 2816 stream processors, 176 TMUs and 64 ROPs. The card has a clock speed of 1055 MHz and has the 8 GB GDDR5 VRAM clocked at 6100 MHz that runs across a 512-bit wide I/O interface.
The Radeon R9 390 Nitro has the Grenada Pro or Hawaii Pro core with 2560 stream processors and is clocked at 1010 MHz while the 8 GB GDDR5 VRAM operates at the same clock speed of 6100 MHz. This model has Nitro cooling with a black shroud.
Antigua (Tonga Pro) based cards which feature 1792 stream processors, 112 TMUs and 32 ROPs. The chip has a clock speed listed at 985 to 980 MHz core with 256-bit memory clocked at 5.7 GHz for the 4 GB and 5.5 GHz for the 2 GB model. There are three models; an ITX-Compact model, the Dual-X OC variant and a Nitro.
Series R7 370
370 is Pitcairn XT with 1024 stream processors, 64 TMUs and 32 ROPs. There are two models listed with 2 GB GDDR5 memory on a Nitro and a Dual-X OC model, core clocks are 1000 MHz and 985 MHz.
Series R7 360
Thid is Bonaire Pro core with 768 stream processors, now called Tobago. The GPU is clocked at 1060 MHz with 2 GB GDDR5 at 6.5 GHz tied to a 128-bit bus interface.
