The rumours are flying today, with some purportedly leaked performance results of AMD's upcoming Fiji XT based card, the Fury X.  The leak at Videocardz shows the results of 3DMark's Firestrike Ultra and Extreme for an AMD Radeon Graphics Processor in single card configuration and Crossfire results for Extreme only.  The results show a card that can keep up with the Titan X and by extension the new GTX 980 Ti as well.  At 1440p resolution, the Firestrike Extreme benchmark, the new AMD card seems to lag slightly behind NVIDIA in single and dual GPU configurations, but not by much while in the Ultra test at 4K the AMD GPU pulls ahead, likely thanks to the new HBM-1 memory.

They also claim to have a source who has run the new GPU though the CompuBench suite which gives us more information about the general architecture.  The tests show a card with 64 Compute Units, which translates into 4096 Stream Cores if it is designed similarly to current Radeons.  The tests also confirm the 1050MHz core clock and more interestingly the 4GB of HBM-1 will be clocked at 500MHz memory clock with a 4096-bit bus, which is good news for those who like their resolutions as high as they can go.  Nothing is confirmed yet but these numbers bode well for the new Radeon architecture if they are true.

Even more information has allegedly leaked out ahead of AMD’s official announcement of new 300-series Radeon GPUs, this time from rumor site WCCFtech. This information is totally unverified at least from any public source, but it is very specific regarding both price and GPU.

Here is the list published by WCCFtech in their report:

Graphics Card GPU Price
R9 390X 8GB Enhanced Hawaii XT $389
R9 390 8GB   Enhanced Hawaii Pro  $329
R9 380X 3GB/6GB    Tonga XT (NOT CONFIRMED)  
R9 380 4GB   Tonga Pro  $235
R9 380 2GB Tonga Pro   $195
R7 370 4GB Pitcairn $175
R7 370 2GB Pitcairn $135
R7 360 2GB Bonaire $107

Credit: WCCFtech

As to whether this comes via leaked slides or is complete guesswork, we’ll likely have no answer until the official unveiling. Such an announcement is likely the purpose of the AMD gaming event at E3 which is now just days away. We can only hope that Fiji will in fact be making an appearance at the show as it does not appear on this list (again, if accurate).

AMD R9 390X Confirmed Hawaii Rebrand via Leaked Box Shot

Tagged: r9 390x, leak, hbm, hawaii, GDDR5, Fiji, amd

On the XFX R9 290X Double Dissipation product page something very curious appears when you scroll all the way down to the bottom…

xfx_1.png

What’s this image over here on the right, I wonder…

R9-390X-8DFR_4.JPG

Well would you look at that. The box is clearly labeled for an AMD Radeon R9 390X with 8GB of GDDR5 memory, further indicating that the upcoming GPU will in fact be a Hawaii rebrand; and that the HBM-based flagship Fiji GPU we keep hearing about (and seeing pictures of) will have a new name. Whether that ends up being R9 490X or a name like “Fury” we will soon find out. As it is, it looks like we know at least part of what to expect from AMD’s gaming event at E3 on June 16.

Hmm. What might this be about??

Of course we will have complete coverage when any official announcement is made, but for now enjoy the accidental product reveal!

Update: XFX has removed the R9 390X images from their R9 290X DD product page, but not before numerous sites took their own screenshots before posting the news as well. There has been some disagreement about what the leaked photos actually reveal, or if anything has genuinely been "confirmed", but it seems likely that the product named 390X will be a rebranded 290X with 8GB of GDDR5.

AMD Carrizo SKUs and Dual Graphics Options Announced

Subject: Graphics Cards, Processors, Mobile | June 4, 2015 - 04:58 PM |
Tagged: amd, carrizo

My discussion of the Carrizo architecture went up a couple of days ago. The post did not include specific SKUs because we did not have those at the time. Now we do, and there will be products: one A8-branded, one A10-branded, and one FX-branded.

amd-2015-carrizo-skus.jpg

All three will be quad-core parts that can range between 12W and 35W designs, although the A8 processor does not have a 35W mode listed in the AMD Dual Graphics table. The FX-8800P is an APU that has all eight GPU cores while the A-series APUs have six. The A10-8700P and the A8-8600P are separated by a couple hundred megahertz base and boost CPU clocks, and 80 MHz GPU clock.

amd-2015-carrizo-dualgpu.jpg

Also, we have been given a table of AMD Radeon R5 and R7 M-series GPUs that can be paired with Carrizo in an AMD Dual Graphics setup. These GPUs are the R7 M365, R7 M360, R7 M350, R7 M340, R5 M335, and R5 M330. They cannot be paired with every Carrizo APU, and some pairings only work in certain power envelopes. Thankfully, this table should only be relevant to OEMs, because end-users are receiving pre-configured systems.

Pricing and availability will depend on OEMs, of course.

AMD's Massive Fiji GPU with HBM Gets Pictured

Subject: Graphics Cards | June 3, 2015 - 08:39 PM |
Tagged: amd, Fiji, radeon, R9, 390x, maybe

Sorry for all of these single item news posts I keep making, but this is how the information is coming out about AMD's upcoming Fiji GPU using new HBM (high bandwidth memory) technology. (And make no mistake this is exactly the way that AMD marketing dreamed it would happen.) Below we have an image of Fiji: the GPU die, the interposer and the four stacks of HBM.

amdfijidie.jpg

Look familiar?

04-fourstacked.jpg

That chip is massive, quite simply, measuring about 70mm x 70mm based on the information presented during our HBM technical session last month. That is gigantic when compared to other GPU dies alone but is smaller than previous generation GPUs and the required memories on the PCB separately. 

In case you missed it earlier today, AMD also released a teaser video of a CG Radeon card using Fiji. We'll know everything (maybe?) about AMD's latest flagship on June 16th.

AMD Teases New Radeon Fiji GPU on June 16th with Video

Subject: Graphics Cards | June 3, 2015 - 03:25 PM |
Tagged: radeon, hype train, hbm, Fiji, amd

The AMD Fiji hype train keeps rolling. Here is a video that AMD posted to its AMD Radeon Graphics Twitter account with a several second long teaser video.

First and foremost, it looks like all of the leaks about the cooler and card design of Fiji were at least mostly accurate. Also, note that AMD included the #AMD300 tag in the tweet, leading us to believe that the R9 390X is indeed going to be the branding.

Looks like we'll know more on June 16th during E3.

Digging into a specific market

A little while ago, I decided to think about processor design as a game. You are given a budget of complexity, which is determined by your process node, power, heat, die size, and so forth, and the objective is to lay out features in the way that suits your goal and workload best. While not the topic of today's post, GPUs are a great example of what I mean. They make the assumption that in a batch of work, nearby tasks are very similar, such as the math behind two neighboring pixels on the screen. This assumption allows GPU manufacturers to save complexity by chaining dozens of cores together into not-quite-independent work groups. The circuit fits the work better, and thus it lets more get done in the same complexity budget.

amd-2015-carrizo-63mil.jpg

Carrizo is aiming at a 63 million unit per year market segment.

This article is about Carrizo, though. This is AMD's sixth-generation APU, starting with Llano's release in June 2011. For this launch, Carrizo is targeting the 15W and 35W power envelopes for $400-$700 USD notebook devices. AMD needed to increase efficiency on the same, 28nm process that we have seen in their product stack since Kabini and Temash were released in May of 2013. They tasked their engineers to optimize their APU's design for these constraints, which led to dense architectures and clever features on the same budget of complexity, rather than smaller transistors or a bigger die.

15W was their primary target, and they claim to have exceeded their own expectations.

Backing up for a second. Beep. Beep. Beep. Beep.

When I met with AMD last month, I brought up the Bulldozer architecture with many individuals. I suspected that it was a quite clever design that didn't reach its potential because of external factors. As I started this editorial, processor design is a game and, if you can save complexity by knowing your workload, you can do more with less.

amd-2015-carrizo-3.jpg

Bulldozer looked like it wanted to take a shortcut by cutting elements that its designers believed would be redundant going forward. First and foremost, two cores share a single floating point (decimal) unit. While you need some floating point capacity, upcoming workloads could use the GPU for a massive increase in performance, which is right there on the same die. As such, the complexity that is dedicated to every second FPU can be cut and used for something else. You can see this trend throughout various elements of the architecture.

Read on for more about what Carrizo is, and what it came from to get here.
