AMD Radeon R300 Grenada is 380X, Fiji is 390X and Bermuda is 395x2

AMD Radeon R300 Grenada is 380X, Fiji is 390X and Bermuda is 395x2

Alright, it's time for some sugar and spice. New specs and codenames for AMDs upcoming Radeon 300 series have surfaced on the web. Initially you will see a Radeon R9 380X and R9 380 graphics released, these now fall under codename Grenanda.

 

Fiji and Bermuda (Radeon R9 390 & 390X & 395x2)

We start with Fiji, this will be an new GCN v1.3 based silicon, that GPU forms the basis of the high-end and enthusiast class products. Very little is know TBH. The latest gossip points towards 4,096 shader processors / GCN 1.3 architecture / 256 TMUs with 128 ROPs, and a 1024-bit wide HBM memory interface, offering 640 GB/s of memory bandwidth. We assume 4 GB will be defacto the the memory amount. Expect the R9 390, the R9 390X, and the 2x Fiji = Bermuda = R9 390X2 to be based on that GPU.

Grenada (Radeon R9 380 & 380X)

Grenada will be based on the good and relatively old 28nm fab process, the GPU will actually be refresh of Hawaii.  Here is the spicy bit as this is going to be rather disappointing for a lot of you guys, Grenada will have the same specs as Hawaii - 2,816 GCN stream processors, 176 TMUs, 64 ROPs, and a 512-bit wide GDDR5 memory interface and is tapping into 4 GB memory (fully usable we assume:). The GPU is different in the sense that it is going to have increased clock frequencies to beat the GTX 980 from Nvidia. We expect a similar TDP, yet better cooling we hope.


Hawaii GPU to be refreshed 

Tonga (Radeon R9 370 & 370X)

The second rumor is that Tonga (R9 285) which had a rather miserable launch will be re-used and form the basis of the Radeon R9 370 series. Tonga has  2,048 shader processors,  GCN 1.3 architecture, 128 TMUs, 32 ROPs, and a 384-bit wide GDDR5 memory interface. We expect these cards to have increased clocks and 3GB of graphics memory.

Trinidad (Radeon R7 360 & 360X)

Trinidad is the low-end segment, and will be the Radeon R7 360 & 360X. Very little is known however this will be a refresh based on Pitcairn.

im thinking the 380x which will compete against the 980 will probably have similar performance against the 980, they'll probably top each other on certain benchmarks like always with competing cards. since it sounds like the 380x is nothing more but a rebranded 290x with a little speed bump, it'll probably have a little better power consumption and cooling but im not holding my breathe knowing AMD's track record in this area.

I find it doubtful that the 380x is going to have superior or even comparable TDP to a 980, being a rebrand.
We'll see.

I'm sure GM200 will be faster. But I'd be retarded to care, because it'll probably be 200 bucks more than the 390X. So I'm going AMD after this one.

If the 380x is indeed using the same core as the 290x, there could be a new revision of the core to do so. Claiming to be as low or comparable to the 980, that I do doubt.

Only 200$ more? Come on... :D
