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.

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 ...

Lol..so the 380 & 380X are nothing but name changed, speed bumped 290 & 290X's.
AMD have had nearly 2yrs to come up with something and the best they can do to rival the 970 & 980 is a different name on the box and a speed bump.
They're doomed if they carry on like this.

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

Speed bumps of 7970 GHz Edition and 280x compared to the regular 7970 were pretty significant. Perhaps it'll be similar in case of 380(x) too. I hope it'll be able to fight 970 and 980, especially as the price of the latter is absurd in EU.
Still, I'd wait for 390(x).

IS IT ME OR IS IT SUPERDUPER QUIET IN THE AMD DRIVER DEVELOPMENTS??

There aren't many new games in January, so the nVidia and AMD driver teams don't have to churn out so many drivers.
Looking at the specks os the cards seems like well be getting just a 1.2 GCN update, like the Tonga refresh a few months back.

GPU rebrands and rehashes are a norm in the industry. Even Nvidia did it with some of their 700 series. It happens a lot more in the low end/entry level segment just that they don't get the limelight. At the very least the Grenada (Hawaii refresh) is getting modernized and performance improved to beat the 980.
Its going to be interesting with Fiji's performance and the 300 series is going to force Nvidia to lower prices again. So even Nvidia fans should rejoice.
Competition FTW.

Damn, I'm disappointed. Last year I was looking at 970 to finally replace my current, ancient video card, but a friend told me it might be worth it to wait for the AMD 300 generation with the all new technology. So, I've been waiting only to learn now that the 380(x) model, which is the highest I could afford as I'd assume 390(x) is going to cost an arm and a leg being the flagship model, will be in fact dusty old technology with absolutely nothing new.
Unless I'll get 380(x) for 300 euros or less (which is impossible, I reckon), then I'm forced to continue with Nvidia. Fortunately it's all the same for me if it's Nvidia or AMD. Rather than never having had problems with either, I've had problems with both equally, har har.

Somebody knows/guess the clock speed r9 "290x" needs to beat 980 (??? reference 980 ???) ?

They really need an update, to match the 980 with grenada. Around 1200ish base clock at least.

Ive had my 380 for over a year now, so its 390 for me.

Give me a Tonga based card on Steroids which beats standart 290 and with 4-6GB Ram with less then 200Watts and i go red with a DP1.2a Monitor.
Otherwise i go green with a G(ay)-Sync monitor and i always will go green until the Monitor DIE.
I really hate this GPU´s this days, why Intel cant make good GPUs, i m really sick of AMD and NVIDIA

IF we want to call cards like 370(x) rebrands, then nearly everything in history of x86 architecture has been rebranded.
Because while Tonga may have GPU compute/rendering part of Tahiti, it has only 256bit bus but has new display controller and TrueAudio, better tessellation. (this means architectural changes)
And if 370(x) is supposed to be Tonga based it would again have to have 256bit bus, but it apparently features 384bit bus.
(if anything, it is not rebrand, it is updated/upgraded Tahiti to GCN 1.3)
Anyway, this is like 5th rumor thread...

If the 380X will be as fast as the GTX 980 and cost like the gtx 970 or lower then gg nVidia

So if R380 is going to fight with GTX980, R390 should be really interesting card. interesting see what NV will come up with.

I will take a 380X if its a rebranded 290X, probably won't be able to fit a 390 with its closed loop cooler in my case any way (if it needs one that is).
