AMD Radeon 300 series this spring – Hawaii will be renamed Grenada and R9 380X

The graphics card maker AMD has not yet responded to Nvidia’s autumn launch of the Geforce GTX 980 and 970, but has so far only contracted with depressed prices or as it is officially called “limited promotions”. This is expected to change in the spring, when AMD launches the partly new Radeon 300 series.

Specifications: AMD Radeon 300 Series

German 3DCenter has compiled a list based on rumors, speculations and what is said to be its own information from partner manufacturers. The list talks about a mix of old and new, where for example the graphics processor Hawaii in the current Radeon R9 290 series is renamed Grenada and the R9 380 series.

Further down the hierarchy are the Radeon R9 370X and 370, which are said to be based on the graphics processor Tonga in the Radeon R9 285. So far, however, it has only been found in a scaled-down version with 1,792 stream processors and 256-bit memory bus, but with the new series also the full-scale variant is launched.

At the bottom of the series and reportedly closest in time is Trinidad, which is the Radeon R7 360X and 360. Previous data speaks of a 256-bit memory bus with 2 GB of GDDR5 memory, which is recognizable from Pitcairn / Curacao in the Radeon R9 270X and 270 which it is intended to replace. What performance differences are to be expected, however, is difficult to say, as the number of stream processors is still shrouded in obscurity.

For those who are looking forward to news in the absolute top tier, there is Fiji, which is said to house the Radeon R9 390 series. It is worth mentioning that an AMD engineer at Linkedin previously spoke in favor of this graphics circuit being used in the Radeon R9 380X, the same as the Grenada. However, it can not be ruled out that AMD has made changes to the name scheme since the name was found online.

For Fiji, up to 4,096 stream processors apply, which according to leaks should be translated into round slings 50 percent higher performance than the Radeon R9 290X. While 3DCenter claims that this is accompanied by a 1,024-bit memory bus, previous data speaks for as many as 4,096 bits, which with stacked HBM memories paves the way for a bandwidth up to a record high 640 GB / s.

The whole thing is rounded off by the mythical Bermuda, which is believed to be a graphics card with dual graphics processors Fiji. As Fiji in the Radeon R9 390X is expected to have a TDP value of 300 W, a possible Radeon R9 395X2 can be expected to be a thirsty story, with the potential to break the 500 W that applies to the Radeon R9 295X2.

First out for launch is Trinidad with the Radeon R7 370 series, which according to previous information arrives in March. This will be followed by the remaining graphics cards during the second quarter of the year, of which the Fiji and Radeon R9 390 series are expected to arrive in connection with or at Computex 2015 in June. However, the Radeon R9 395X2 monster card is expected to arrive much later, for Christmas shopping in 2015.
