Jaguar Hits the Embedded Space
It has long been known that AMD has simply not had a lot of luck going head to head against Intel in the processor market. Some years back they worked on differentiating themselves, and in so doing have been able to stay afloat through hard times. The acquisitions that AMD has made in the past decade are starting to make a difference in the company, especially now that the PC market that they have relied upon for revenue and growth opportunities is suddenly contracting. This of course puts a cramp in AMD’s style, but with better than expected results in their previous quarter, things are not nearly as dim as some would expect.
Q1 was still pretty harsh for AMD, but they maintained their marketshare in both processors and graphics chips. One area that looks to get a boost is that of embedded processors. AMD has offered embedded processors for some time, but with the way the market is heading they look to really ramp up their offerings to fit in a variety of applications and SKUs. The last generation of G-series processors were based upon the Bobcat/Brazos platform. This two chip design (APU and media hub) came in a variety of wattages with good performance from both the CPU and GPU portion. While the setup looked pretty good on paper, it was not widely implemented because of the added complexity of a two chip design plus thermal concerns vs. performance.
AMD looks to address these problems with one of their first, true SOC designs. The latest G-series SOC’s are based upon the brand new Jaguar core from AMD. Jaguar is the successor to the successful Bobcat core which is a low power, dual core processor with integrated DX11/VLIW5 based graphics. Jaguar improves performance vs. Bobcat in CPU operations between 6% to 13% when clocked identically, but because it is manufactured on a smaller process node it is able to do so without using as much power. Jaguar can come in both dual core and quad core packages. The graphics portion is based on the latest GCN architecture.

Now that AMD’s dual-gpu Malta graphics card is official, cards from Add-In Board (AIB) partners are starting to roll in. One such recently announced card is the XFX Radeon HD 7990 card. The XFX card is based on the reference AMD design, which includes two Radeon HD 7970 GPUs in a Crossfire configuration.
The two GPUs can boost up to 1GHz clock speeds and feature a total of 4096 stream processors, 256 texture units, 64 ROPs, and 8.6 billion transistors. The card also includes 3GB of GDDR5 memory per GPU running off a 384-bit bus. It supports AMD’s Eyefinity technology and offers up one DL-DVI and four mini-DisplayPort video outputs.
The XFX HD 7990 uses the reference AMD heatsink as well, which includes a massive aluminum fin stack with five copper heatpipes that run the length of the heasink and directly touch the two 7970 GPUs. Three shrouded fans, in turn, keep the heatsink cool.
The dual-GPU monster is eligible for AMD’s Never Settle bundle which includes eight free games. With purchase of the HD 7990 (from any eligible AIB), you get free key codes for the following games:
- Bioshock Infinite
- Crysis 3
- Deus Ex: Human Revolution
- Far Cry 3
- Far Cry 3: Blood Dragon
- Hitman: Absolution
- Sleeping Dogs
- Tomb Raider
The XFX press release further assures gamers that the card can, in fact, play Crysis 3 at maximum settings at a resolution of 3840 x 2160. The company did not mention pricing, however.
For those interested in AMD’s new Malta GPU, check out our review as well as how the card performs when paired with a prototype AMD driver that seeks to address some of the frame rating issues exhibited by AMD's Crossfire multi-GPU solution.

PowerColor (a TUL corporation brand) launched its dual-GPU Radeon HD 7990 V2 graphics card, and this time the card is based on the (recently reviewed) official dual-GPU AMD “Malta” GPU announced at the Games Developers Conference (GDC). The new HD 7990 V2 graphics card features two AMD HD 7970 cards in a Crossfire configuration. That means that the Malta-based card features a total of 4096 stream processors, and a rated 8.2 TFLOPS of peak performance.
The PowerColor HD 7990 V2 joins the company’s existing Devil 13 and HD 7990 graphics cards. The new card sports a triple-fan shrouded heatsink that is somewhat tamer-looking that the custom Devil 13. Other hardware includes 3GB of GDDR5 RAM per GPU clocked at 1500MHz and running on a 384-bit bus (again, per GPU) for a total of 6GB. Both GPUs have clock speeds of 950MHz base and up to 1GHz boost.
The new GPU has a single DL-DVI and four mini-DisplayPort video outputs. PowerColor is touting the card’s Eyefinity prowess as well as its ZeroCore support for reducing power usage when idle. The board has a TDP of 750W and is powered by two PCI-E power connections. In all, the HD 7990 V2 graphics card measures 305 x 110 x 38mm. While PowerColor has not released pricing or availability, expect the card to be available soon and around the same price (or a bit lower than) as its existing (custom) HD 7990.
The full press release can be found here.

We've seen tests of dual 7970s in CrossFire simulating a 7990 and ASUS released the ARES II which was the closest we had until today with the release of the reference HD 7990. There are many reviews to chose from when looking at this new flagship card, such as from a pure performance perspective such as [H]ard|OCP's which did not come out well for AMD's new card. If you are more interested in our new Frame Rating process then there are two reviews to read, one that deals with the 7990 on the publicly available driver and perhaps more interesting is a prototype driver provided to Ryan that is intended to fix Crossfire stuttering on single displays but not for EyeFinity
"Today marks the launch of AMD's Radeon HD 7990. The Radeon HD 7990 is a dual-GPU video card that has its two GPUs down on a single PCB that uses CrossFire to operate the two Radeon HD 7970 GPUs. We will test this video card in the latest games, comparing it to GeForce GTX 680 SLI and Radeon HD 7970 GHz Edition CrossFire. "

The card we have been expecting
Despite all the issues that were brought up with our new graphics performance testing methodology we are calling Frame Rating, there is little debate in the industry that AMD is making noise once again in the graphics field. From the elaborate marketing and game bundles with all Radeon HD 7000 series cards over the last year to the hiring of Roy Taylor, VP of sales but also the company's most vocal supporter.
Along with the marketing though goes plenty of technology and important design wins. With the dominance of the APU on the console side (Wii U, Playstation 4 and the next Xbox), AMD is making sure that the familiarity with its GPU architecture there pays dividends on the PC side as well. Developers will be focusing on AMD's graphics hardware for 5-10 years with the console generation and that could result in improved performance and feature support for Radeon graphics for PC gamers.
Today's release of the Radeon HD 7990 6GB Malta dual-GPU graphics card shows a renewed focus on high-end graphics markets since the release of the Radeon HD 7970 in January of 2012. And while you may have seen something for sale previously with the HD 7990 name attached, those were custom designs built by partners, not by AMD.
Both ASUS and PowerColor currently have high-end dual-Tahiti cards for sale. The PowerColor HD 7990 Devil 13 used the brand directly but ASUS' ARES II kept away from the name and focused on its own high-end card brands instead.
The "real" Radeon HD 7990 card was first teased at GDC in March and takes a much less dramatic approach to its design without being less impressive technically. The card includes a pair of Tahiti, HD 7970-class GPUs on a single PCB with 6GB of total memory. The raw specifications are listed here:
Considering there are two HD 7970 GPUs on the HD 7990, the doubling of the major specs shouldn't be surprising though it is a little deceiving. There are 8.6 billion transistors yes, but there are still 4.3 billion on each GPU. Yes there are 4096 stream processors but only 2048 on each GPU requiring software GPU scaling to increase performance. The same goes with texture fill rate, compute performance, memory bandwidth, etc. The same could be said for all dual-GPU graphics cards though.
A very early look at the future of Catalyst
Today is a very interesting day for AMD. It marks both the release of the reference design of the Radeon HD 7990 graphics card, a dual-GPU Tahiti behemoth, and the first sample of a change to the CrossFire technology that will improve animation performance across the board. Both stories are incredibly interesting and as it turns out both feed off of each other in a very important way: the HD 7990 depends on CrossFire and CrossFire depends on this driver.
If you already read our review (or any review that is using the FCAT / frame capture system) of the Radeon HD 7990, you likely came away somewhat unimpressed. The combination of a two AMD Tahiti GPUs on a single PCB with 6GB of frame buffer SHOULD have been an incredibly exciting release for us and would likely have become the single fastest graphics card on the planet. That didn't happen though and our results clearly state why that is the case: AMD CrossFire technology has some serious issues with animation smoothness, runt frames and giving users what they are promised.
Our first results using our Frame Rating performance analysis method were shown during the release of the NVIDIA GeForce GTX Titan card in February. Since then we have been in constant talks with the folks at AMD to figure out what was wrong, how they could fix it, and what it would mean to gamers to implement frame metering technology. We followed that story up with several more that showed the current state of performance on the GPU market using Frame Rating that painted CrossFire in a very negative light. Even though we were accused by some outlets of being biased or that AMD wasn't doing anything incorrectly, we stuck by our results and as it turns out, so does AMD.
Today's preview of a very early prototype driver shows that the company is serious about fixing the problems we discovered.
If you are just catching up on the story, you really need some background information. The best place to start is our article published in late March that goes into detail about how game engines work, how our completely new testing methods work and the problems with AMD CrossFire technology very specifically. From that piece:
It will become painfully apparent as we dive through the benchmark results on the following pages, but I feel that addressing the issues that CrossFire and Eyefinity are creating up front will make the results easier to understand. We showed you for the first time in Frame Rating Part 3, AMD CrossFire configurations have a tendency to produce a lot of runt frames, and in many cases nearly perfectly in an alternating pattern. Not only does this mean that frame time variance will be high, but it also tells me that the value of performance gained by of adding a second GPU is completely useless in this case. Obviously the story would become then, “In Battlefield 3, does it even make sense to use a CrossFire configuration?” My answer based on the below graph would be no.
An example of a runt frame in a CrossFire configuration
NVIDIA's solution for getting around this potential problem with SLI was to integrate frame metering, a technology that balances frame presentation to the user and to the game engine in a way that enabled smoother, more consistent frame times and thus smoother animations on the screen. For GeForce cards, frame metering began as a software solution but was actually integrated as a hardware function on the Fermi design, taking some load off of the driver.

Tagged: amd, never settle, never settle reloaded, bundle
While browsing around on Twitter today I saw mention of a leaked slide on the Tech Report forums that seems to point in the direction of upcoming games to be included in future AMD Never Settle gaming bundles. AMD has been knocking the ball out of the park when it comes to bundled software with graphics card releases as they have gotten essentially every major PC game in the last 12 months.
This slide indicates that Grid 2, Company of Heroes 2, Rome: Total War II, Splinter Cell Blacklist, Lost Planet 3, Battlefield 4, Raven's Cry and Watch Dogs will all eventually make their way to the AMD bundle list at some point this year. Whether it will be in one mega-bundle or several different promotions throughout the year isn't known, but AMD is serious about keeping up appearances in the PC gaming front.

AMD64 arrived a decade ago with the launch of the first Opteron processor in April of 2003, back in the days when NVIDIA made motherboards and ATI was a separate company. In those days AMD looked like serious competition for Intel as they were out innovating Intel and competing for Big Blue's niche markets as they were first to cross the GHz line and the first to offer a 64bit architecture on a commercially available platform. At that point Intel actually licensed AMD64, re-branded it as x86-64 and used it on their Xeon processor line, a huge victory for AMD. Unfortunately there was not much in the way of consumer software capable of taking advantage of 64-bit architecture and unfortunately remains so to this day, apart from peoples ability to benefit from the enlarged RAM pool allowed. Take a walk down memory lane at The Inquirer, and remember the good old days when AMD was prospering.
"A DECADE AGO AMD released the first Opteron processor and with it the first 64-bit x86 processor."

Tagged: raja koduri, apple, amd
Interesting information has surfaced today about the addition of a new executive at AMD. Raja Koduri, who previously worked for ATI and AMD as Chief Technology Officer, departed the company in 2009 for a four year stint at Apple, helping to turn that company into an SoC power house. Developing its own processors has enabled Apple to stand apart from the competition in many mobile spaces and Koduri is partly responsible for the technological shift at Apple.
Starting on Monday though, Raja Koduri is officially back at AMD, taking over as the CVP (Corporate Vice President) of Visual Computing. This position will result in more complete control over the entirety of the hardware and software platforms AMD is developing including desktop discrete, mobile and APU/SoC designs. This marks the second major returning visionary executive in recent memory to AMD, the first of which was Jim Keller in August of 2012 (also returning from a period with Apple).
It will take some time for Koduri to have effect on AMD's current roadmap
Having known Raja Koduri for quite a long time I have always seen the man as an incredibly intelligent engineer that was able to find strengths in designs that others could not. Much of the success of the ATI/AMD GPU divisions during the 2000s was due to Koduri's leadership (among others of course) and I think having him back at AMD at an even more senior role is great news for both discrete graphics fans and APU users.
In a discussion with Koduri recently, Anandtech got some positive feedback for PC gamers:
Raja believes there’s likely another 15 years ahead of us for good work in high-end discrete graphics, so we’ll continue to see AMD focus on that part of the market.
Koduri sees 15 years more GPU evolution
So even though this hiring isn't going to change AMD's position on the APU and SoC strategy, it is good to have someone at the CVP level that sees the importance and value of discrete, high power GPU technology.
In many talks with AMD over the last 6 months we kept hearing about the healthy influx of quality personnel though much of it was still under wraps. Keller was definitely one of them and Koduri is another and both of the hires give a lot of hope for AMD as a company going forward. Some in the industry have already written AMD off but I find it hard to believe that this caliber of executive would return to a sinking ship.
