While it was reported a year ago that AMD's Tonga XT GPU had a 384-bit memory bus in articles sourcing the same PC Watch report, when the Radeon R9 380X was released last month we saw a Tonga XT GPU with a 256-bit memory interface.

Reports of the upcoming card had consistently referenced the wider 384-bit bus, and tonight we are able to officially confirm that Tonga (not just Tonga XT) has been 384-bit capable all along, though this was never enabled by AMD. The reason? The company never found the right price/performance combination.
AMD confirms 384-bit bus available on Tonga, just not enabled on any product, including 380X. Didn't find a perfect perf/$ slot.

AMD's Raja Koduri confirmed Tonga's 384-bit bus tonight, and our own Ryan Shrout broke the news on Twitter.
So does this mean an upcoming Tonga GPU could offer this wider memory bus? Tonga itself was a follow-up to Tahiti (R9 280/280X), which did have a 384-bit bus, but all along the choice had been made to keep the updated core at 256-bit.
Now more than a year after the launch of Tonga a new part featuring a fully enabled memory bus doesn't seem realistic, but it's still interesting to know that significantly more memory bandwidth is locked away from owners of these cards.

The full serving of Tonga in the AMD Radeon R9 380X has 32 compute units, 2048 stream processors, 32 ROPs and 128 texture units which compares favourably to the 23CUs, 1792 stream processors, 32 ROPs and 112 texture units of the existing R9 380. Memory bandwidth and amount is unchanged, 182GB/sec of memory bandwidth at the stock speed of 5.7GHz effective and the GPU clock remains around 970MHz as well. The MSRP is to be $230 for the base model.
With the specifications out of the way, the next question to answer is how it fares against the direct competition, the GTX 960 and 970. That is where this review from [H]ard|OCP comes in, with a look at the ASUS STRIX R9 380X DirectCU II OC, running 1030MHz default and 1050MHz at the push of a button. Their tests at 1440p were a little disappointing, the card did not perform well until advanced graphics settings were reduced but at 1080p they saw great performance with all the bells and whistles turned up. The pricing will be key to this product, if sellers can keep it at or below MSRP it is a better deal than the GTX 970 but if the prices creep closer then the 970 is the better value.
"AMD has let loose the new AMD Radeon R9 380X GPU, today we evaluate the ASUS STRIX R9 380X OC video card and find out how it compares to a 4GB GeForce GTX 960 and GeForce GTX 970 for a wide picture of where performance lies at 1440p or where it does not at 1440p considering your viewpoint."

AMD will reportedly be launching their latest performance graphics card soon, and specs for this rumored R9 380X have now been reported at VR-Zone (via Hardware Battle).
(Image credit: VR-Zone)
Here are the full specifications from this report:
- GPU Codename: Antigua
- Process: 28 nm
- Stream Processors: 2048
- GPU Clock: Up to 1000 – 1100 MHz (exact number not known)
- Memory Size: 4096 MB
- Memory Type: GDDR5
- Memory Interface: 256-bit
- Memory Clock: 5500 – 6000 MHz (exact number not known)
- Display Output: DisplayPort 1.2, HDMI 1.4, Dual-Link DVI-D
The launch date is reportedly November 15, and the card will (again, reportedly) carry a $249 MSRP at launch.
The 380X would build on the existing R9 285
Compared to the R9 280X, which also offers 2048 stream processors, a boost clock up to 1000 MHz, and 6000 MHz GDDR5, the R9 380X would lose memory bandwidth due to the move from a 384-bit memory interface to 256-bit. The actual performance won’t be exactly comparable however, as the core (Antigua, previously Tonga) will share more in common with the R9 285 (Tonga), though the R9 285 only offered 1792 Stream processors and 2 GB of GDDR5.
You can check out our review of the R9 285 here to see how it performed against the R9 280X, and it will certainly be interesting to see how this R9 380X will fare if these specifications are accurate.

So far the only published review with benchmarks is this one from Legion Hardware, with many others including Ryan's to follow as the benchmark monkeys are whipped to a furious pace. The initial results show roughly what has been expected, the R9 390X is roughly 10% faster overall than the 290X and about 6% faster than the base 390 model which itself is roughly 8% faster than the previous 290. The 380 shows a similar 6% gain over the 285 and performance wise can tie the GTX 960. Bear in mind this is very preliminary review, as time is needed to properly test and to overclock the cards, keep your eyes peeled for more reviews and cards from other sources.
"Firstly we would like to thank HIS for supplying their HIS Radeon R9 390X IceQ X2 OC 8GB, R9 390 IceQ X2 OC 8GB and R9 380 IceQ X2 OC 2GB graphics cards. The cooling performance of their IceQ X2 cooler was excellent on all three cards and they look very eye catching as well."

Big Things, Small Packages
Sapphire isn’t a brand we have covered in a while, so it is nice to see a new and interesting product drop on our door. Sapphire was a relative unknown until around the release of the Radeon 9700 Pro days. This was around the time when ATI decided that they did not want to be so vertically integrated, so allowed other companies to start buying their chips and making their own cards. This was done to provide a bit of stability for ATI pricing, as they didn’t have to worry about a volatile component market that could cause their margins to plummet. By selling just the chips to partners, ATI could more adequately control margins on their own product while allowing their partners to make their own deals and component choices for the finished card.
ATI had very limited graphics card production of their own, so they often would farm out production to second sources. One of these sources ended up turning into Sapphire. When ATI finally allowed other partners to produce and brand their own ATI based products, Sapphire already had a leg up on the competition by being a large producer already of ATI products. They soon controlled a good portion of the marketplace by their contacts, pricing, and close relationship with ATI.
Since this time ATI has been bought up by AMD and they no longer produce any ATI branded cards. Going vertical when it come to producing their own chips and video cards was obviously a bad idea, we can look back at 3dfx and their attempt at vertical integration and how that ended for the company. AMD obviously produces an initial reference version of their cards and coolers, but allows their partners to sell the “sticker” version and then develop their own designs. This has worked very well for both NVIDIA and AMD, and it has allowed their partners to further differentiate their product from the competition.
Sapphire usually does a bang up job on packaging the graphics card. Oh look, a mousepad!
Sapphire is not as big of a player as they used to be, but they are still one of the primary partners of AMD. It would not surprise me in the least if they still produced the reference designs for AMD and then distributed those products to other partners. Sapphire is known for building a very good quality card and their cooling solutions have been well received as well. The company does have some stiff competition from the likes of Asus, MSI, and others for this particular market. Unlike those two particular companies, Sapphire obviously does not make any NVIDIA based boards. This has been a blessing and a curse, depending on what the cycle is looking like between AMD and NVIDIA and who has dominance in any particular marketplace.

Benchlife.info, via WCCFTech, believes that AMD's Radeon R9 300-series GPUs will launch in late June. Specifically, the R9 380, the R7 370, and the R7 360 will arrive on the 18th of June. These are listed as OEM parts, as we have mentioned on the podcast, which Ryan speculates could mean that the flagship Fiji XT might go by a different name. Benchlife.info seems to think that it will be called by the R9 390(X) though, and that it will be released on the 24th of June.
WCCFTech is a bit more timid, calling it simply “Fiji XT”.
In relation to industry events, this has the OEM lineup launching on the last day of E3 and Fiji XT launching in the middle of the following week. This feels a little weird, especially because AMD's E3 event with PC Gamer is on the 16th. While it makes sense for AMD to announce the launch a few days before it happens, that doesn't make sense for OEM parts unless they were going to announce a line of pre-built PCs. The most likely candidate to launch gaming PCs is Valve, and they're one of the few companies that are absent from AMD's event.
And this is where I run out of ideas. Launching a line of OEM parts at E3 is weird unless it was to open the flood gates for OEMs to make their own announcements. Unless Valve is scheduled to make an announcement earlier in the day, or a surprise appearance at the event, that seems unlikely. Something seems up, though.

It will not be officially rolled in until kernel 4.2 but you can currently grab the new binary blob by following the links from Phoronix. This new AMDGPU kernel driver will be used by both the full open-source driver and the Catalyst driver provided officially by AMD and provide support not only for the R9 285 but upcoming families as well. There is still some development to be done as AMD's Alex Deucher told Phoronix that this initial code lacks power management features for Tonga but that will be addressed shortly.
"At long last the source code to the new AMDGPU driver has been released! This is the new driver needed to support the Radeon R9 285 graphics card along with future GPUs/APUs like Carrizo. Compared to the existing Radeon DRM driver, the new AMDGPU code is needed for AMD's new unified Linux driver strategy whereby the new Catalyst driver will be isolated to being a user-space binary blob with both the full open-source driver and the Catalyst driver using this common AMDGPU kernel driver."

MSI's Radeon R9 285 GAMING OC does not yet show up for sale but with it's factory overclock may arrive at a slightly higher price than the MSRP of $250. The RAM remains at the default 5.5 GHz but the GPU has been bumped up 55MHz to 973MHz out of the box and could likely be pushed higher as MSI has included the usual suspects on this card, Twin Frozr IV Advanced and Military Class 4 components. In [H]ard|OCP's testing the card was well matched by the GTX 760, the HD 285 won more than it lost, but not always and not by much. Compared to the HD 280 not only did the new Tonga card usually provide better performance but the additional feature the GPU supports, of which FreeSync is only one, make the HD 285 the clear winner in that contest. Check their full review for benchmarks.
"AMD has launched the $249 AMD Radeon R9 285 video card. We dive into this somewhat confusing GPU. We compare it to the GeForce GTX 760 as well as an AMD Radeon R9 280. We'll discuss GCN differences in this new video card that may give it the edge with some feedback from AMD."

Tonga GPU Features
On December 22, 2011, AMD launched the first 28nm GPU based on an architecture called GCN on the code name Tahiti silicon. That was the release of the Radeon HD 7970 and it was the beginning of an incredibly long adventure for PC enthusiasts and gamers. We eventually saw the HD 7970 GHz Edition and the R9 280/280X releases, all based on essentially identical silicon, keeping a spot in the market for nearly 3 years. Today AMD is launching the Tonga GPU and Radeon R9 285, a new piece of silicon that shares many traits of Tahiti but adds support for some additional features.
Replacing the Radeon R9 280 in the current product stack, the R9 285 will step in at $249, essentially the same price. Buyers will be treated to an updated feature set though including options that were only previously available on the R9 290 and R9 290X (and R7 260X). These include TrueAudio, FreeSync, XDMA CrossFire and PowerTune.
Many people have been calling this architecture GCN 1.1 though AMD internally doesn't have a moniker for it. The move from Tahiti, to Hawaii and now to Tonga, reveals a new design philosophy from AMD, one of smaller and more gradual steps forward as opposed to sudden, massive improvements in specifications. Whether this change was self-imposed or a result of the slowing of process technology advancement is really a matter of opinion.
