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.

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.

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.

Look familiar?

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.

Support for AMD A-Series ‘Godavari’ APUs

AMD Catalyst 15.5 Beta Driver Improves Project Cars and Witcher 3 Performance

Subject: Graphics Cards | May 29, 2015 - 11:26 AM |
Tagged: catalyst, amd, 15.5 beta

Last night AMD released a new Catalyst driver, 15.5 Beta, that targets performance improvements in both Project Cars and The Witcher 3: Wild Hunt. You can pick up the new driver for both 32-bit and 64-bit versions of Windows 7 and Windows 8.1 right here. The full display driver version is 14.502.1014.1001.

The specific changes?

Highlights of AMD Catalyst™ 15.5 Beta Windows Driver

Crossfire Profile Update for:

  • The Witcher 3 - Wild Hunt

Performance Improvements for the following :

  • The Witcher 3 - Wild Hunt :  Up to 10% performance increase on single GPU Radeon R9  and R7 Series graphics products
     
  • Project Cars - Up to 17% performance increase on single GPU Radeon R9 and R7 Series graphics products

Users of the Radeon R9 295X2 will be glad to see support for their hardware added for The Witcher 3 and just about everyone will be glad to see some dramatic performance improvements in Project Cars and Witcher 3. We know from testing internally as well as widely reported issues that AMD Radeon graphics cards had issues with Project Cars, resulting in performance well behind comparable NVIDIA GeForce hardware. With as much as 17% improvement for Radeon R9 and R7 hardware though, hopefully that frame rate increases quite a bit.

Rumor: AMD To Name Upcoming Flagship Fiji GPU "Radeon Fury"

Subject: Graphics Cards | May 29, 2015 - 11:05 AM |
Tagged: rumors, radeon, hbm, graphics, gpu, Fury, Fiji, amd

Another rumor has emerged about an upcoming GPU from AMD, and this time it's a possible name for the HBM-powered Fiji card a lot of us have been speculating about.

New box art revealed! (Or a product from early 2000.) Image: VideoCardz

The rumor from VideoCardz via Expreview (have to love the multiple layers of reporting here) states the the new card will be named Radeon Fury:

"Radeon Fury would be AMD’s response to growing popularity of TITAN series. It is yet unclear how AMD is planning to adopt Fury naming schema. Are we going to see Fury XT or Fury PRO? Well, let’s just wait and see. This rumor also means that Radeon R9 390X will be a direct rebrand of R9 290X with 8GB memory."

Of course this is completely unsubstantiated, and Fury is a branding scheme from the ATI days, but who knows? I can only hope that if true, AMD will adopt all caps: TITAN! FURY! Feel the excitement. What do you think of this possible name for the upcoming AMD flagship GPU?

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.

r9_285_itx_01.jpg

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.

r9_285_itx_02.jpg

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.
