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.
AMD Radeon R9 390X Performance Numbers Surface - 11/26/2014 02:46 PM
It is rumored that AMD is working hard on releasing the next high-end graphics cards, tagged as Radeon R9 390X (or 380X). Asian website Chiphell now has posted a couple of benchmarks in their forums ...
AMD Radeon 390 and 390X Specs and Benchmarks ? - 11/11/2014 08:57 AM
Interesting news, over at the ranking system of SiSoft Sandra new entries have been spotted of what seem to be GPUs that we don't know of. And the specs are pretty appealing. Let's call the two entr...
AMD Radeon R9 285 Launches September 2nd - 08/22/2014 07:00 AM
AMD has kept the wraps on this one tight, however a document shows that the Tonga based Radeon R9 285 will be released onb the 2nd September, 2014. Tomorrow August 23rd AMD is celebrating 30 years o...
Review: AMD Radeon R7 Series SSD - 08/20/2014 04:49 AM
We review the AMD Radeon R7 series SSD. Based on an Indilinx Barefoot 3 controller the product comes with the latest iteration of Toshiba NAND flash memory. The end result is an SSD that is very fast ...
Several AMD Radeon R9 285 Tonga based GPU cards Spotted - 08/11/2014 09:17 AM
It was rumored already that AMD is about to release a R9 285 based on the new Tonga GPU. Tonga will likely have the very rather similar shader processor count as one of the "Tahiti" GPUs ...

Depends, they had 1 year time to optimize 290x chip further.. ~1200mhz is enough to surpass it, same as 780Ti ~ 1170mhz..
http://www.overclock.net/t/1515264/gtx-980-vs-gtx-780-ti-benchmarked-1440p-performance
I saw one bench clock for clock @ 1000mhz 780ti vs 980gtx, 780ti beat it in everything.
if 290X gets the Tonga updates, then the 980 is pretty much done at stock, but that would mean AMD would have 2 300W GPUs on the market, and one that doesn't overclock for crap (this 380X). I wonder if it will be fully DX12.
Anyway in all games little Maxwell has enough of a lead on big Kepler. Ryse, Dying Light, The Crew (Kepler gets crushed) and pretty much any game to come. Drivers have come along nicely.
That will destroy a 980 and it will probably match my 970 SLI performance wise!!
Yes, yes it will. :/
970 SLI should be faster though.

Idk I played Ryse Son of Rome above 60fps on mine, but yeah it was Oc'ed to 1100mhz..
Anyway not really relevant, I think 390X will be the bomb, much much bigger bomb then GK110 or 290x was, just like Geforce GM200.
There are few exception benchmarks, like always, but overall its still the same.
Stock 780Ti, slight OC from stock 928mhz boost to ~ 1100mhz makes a big difference.

Those are old. Right this moment 780ti is so crippled that cant even beat 970. You can thank nvidia for that...

What about the 390, 390x and 395x2? You focus on 380 and 380x which will be made to fight 970 and 980 respectively. I bet it will be a -15% difference or so on price.
nV will answer with their 980ti or titan2 and then amd, half a year later, with 390x and then 395x2... This will never end lol
So it's okay for you to make an excuse for AMD to rebrand 290 and 290x, but it's okay to bash Nvidia for 500mb of slower Vram that instead acts like a buffer.
Yeah okay.
That is why these comments are invalid. They don't make any sense.

AMD's excuse would be no 20nm tech. nVIDIA's is communication error.
Nice comparison.

Oh my good lord!!!
That 390X looks like a total beast!!
4096 shaders, 256 TMU's, 128 ROPS, 1024-bit bus..... 640GB/s bandwidth!!
That will destroy a 980 and it will probably match my 970 SLI performance wise!!
I think this is the time to sell my 970's and jump back to AMD!!!
Please god let the prices be good but more importantly I want good temps!!!
