 AMD’s CPU Roadmap, 2008-2011 | Page:: ( 1 / 2 ) |
Because these details were already disclosed last month in Japan, the real news wasn’t made in graphics, rather AMD has made sweeping changes to their CPU roadmap. The following chart quickly summarizes the changes:
As you can see, AMD has totally reworked their mobile CPU roadmap, with four new cores slated for release between now and the end of 2010, “Caspian”, “Conesus”, “Champlain”, and “Geneva”. The desktop roadmap is dominated by Deneb, which we now know has been officially branded as Phenom II. Then in 2011, AMD plans to introduce Orochi for high-end desktops as well as their first CPU-GPU hybrid processors (AMD refers to them as APUs or accelerated processing units) that combine traditional CPU processing with graphics duties. These processors are codenamed “Llano” and “Ontario”.
Previously AMD’s roadmap indicated we’d see the first CPU-GPU APUs in 2009 with the introduction of their Swift processors. At the time of AMD’s ATI acquisition in 2006, the company made the case that their 45-nm manufacturing process was the right time for the CPU to gain graphics functionality, now the company feels that the tech isn’t feasible until they shrink to 32-nm with Llano and Ontario, with the Swift core disappearing entirely from AMD’s new roadmap.
Until we see the introduction of the first APUs however, AMD plans to service the mobile segment with more conventional 45-nm processors.
Up first will be Caspian, Conesus, and Huron, all slated to be introduced in the second half of 2009.
Caspian is AMD’s solution for mainstream notebooks. Like today’s Griffin-based Turion X2 CPUs, the Caspian core will feature two processing cores with 2MB of cache and DDR2 memory. Unfortunately AMD wouldn’t provide further details on Caspian’s architecture (i.e. is the core simply a die-shrink of Griffin or are its origins based on Phenom II), when asked the company declined to answer the question. However, the “S1G3” (socket 1 generation 3) designation in the second chart implies that it’s definitely more advanced than just a simple die-shrink of Griffin, although it may not be quite as complex as Phenom II to keep power consumption and die size down.

Caspian will ship with AMD’s next-generation Tigris platform, which replaces today’s Puma. Tigris will feature a new RS880M North Bridge + SB710 South Bridge. Once again AMD wasn’t specific on details when it comes to RS880M, so we don’t know if it’s derived from RV770 or RV870 technology. AMD also expects manufacturers to offer Tigris-based notebooks with discrete graphics, presumably using upcoming Mobility Radeon 4000 parts.
Moving further down the rung, for the ultraportable/mini-notebook (netbook) segment, AMD plans to offer Conesus in 2H’09. Yesterday, rumors were swirling that AMD would offer a CPU to rival Intel’s Atom CPU. Today AMD reiterated their position on the topic: NO! The company still feels consumers want a more fully-fledged notebook experience with no compromises; as anyone who has tried to seriously game or encode a video on a netbook can tell you, Intel’s Atom CPU really isn’t up to the task for these duties. Rather than offer a dedicated CPU for the netbook segment, AMD plans to counter with lower priced ultraportable systems based around Conesus and Huron.
Conesus is a dual-core part with 1MB of cache and DDR2, while Huron is a single-core CPU. Conesus will rely on AMD’s upcoming Congo platform, which consists of RS780M + SB710 South Bridge, while Huron will ship with Yukon, which will utilize RS690E + SB600. To minimize power consumption we’d guess that these chipsets will be built using TSMC’s 40-nm manufacturing process, although AMD wouldn’t provide specifics on that topic either.

Also due in 2010 is Geneva. Geneva is a dual-core, lower power part with 2MB of cache and DDR3.
As we mentioned on the previous page, we’ll see the first APUs from AMD in 2011, a delay of roughly two years from AMD’s original plans due to their decision to wait for 32-nm before producing a CPU-GPU part. AMD actually expects to begin producing 32-nm parts in 2010, although the process won’t be ready for mass production until 2011. If the first 32-nm samples look good in 2010, it’s conceivable that Llano and Ontario could be introduced in the first half of 2011, although AMD wouldn’t provide anything specific here.

AMD’s desktop plans
Earlier this morning AMD revealed the brand name for their first 45-nm desktop CPUs based on their Deneb core, Phenom II. This afternoon AMD revealed one new nugget of info about Phenom II – it’s launching in early January at CES in Las Vegas alongside AMD’s Dragon platform.
Phenom II will ship with 8MB of cache and will initially support DDR2 memory and AMD’s AM2+ socket. The CPU is also rumored to launch at clock speeds as high as 3.0GHz. (Newer reports have also suggested that Phenom II will scale much better than Phenom when it comes to overclocking.) Later in 2009 the processor will transition to AMD’s AM3 socket with support for DDR3 memory.

This brings us to Dragon, AMD’s new platform for Phenom II. Apparently Dragon doesn’t refer to AMD’s next-generation RD890 chipset, but 700-series chipsets with AMD’s new SB750 South Bridge. RD890 may not appear until well into 2009, perhaps as late as the second half of next year.
For the mainstream desktop CPU segment AMD plans to offer Propos. Propos is a quad-core part with just 2MB of total cache.
According to AMD’s latest roadmap, both Deneb and Propos will serve as AMD’s primary desktop CPUs for 2009 and 2010. In our opinion this is an awfully conservative move on AMD’s part, particularly for 2010. Over that same time frame Intel is slated to offer Westmere (their 32-nm Nehalem refresh part) and Sandy Bridge, which is Intel’s next-generation CPU architecture beyond Nehalem. To put things in perspective, Deneb is expected to bring AMD on par with Intel’s Penryn processors when it comes to performance, so by the time AMD’s next-generation desktop core is ready in 2011, Intel could be two generations beyond them.
Bulldozer, now codenamed “Orochi”, could be a powerful processor when it arrives in 2011 though. AMD plans to outfit the processor with more than four cores and more than 8MB of cache. Little is known beyond that, although we do know it will utilize AMD’s 32-nm manufacturing process.
Combining a new manufacturing process with a new microarchitecture could be tricky for AMD. Both AMD and Intel have learned the hard way how difficult it can be pulling off a new architecture alone, and they’ve both also had their fair share of difficulties with rolling out a new manufacturing process, so if AMD can pull both off simultaneously with Orochi it would be quite a coup for the company. Our guess is Orochi must have some type of game-changing feature that needs 32-nm for it to be worth the risk for AMD to combine both in one processor.
Conclusion
If you’re a hardcore AMD enthusiast holding out for the return of the FX line and AMD’s CPU supremacy, chances are you’re going to be waiting quite a while. 2011 at the very earliest. AMD has repeatedly stated that Deneb is not a performance competitor with Intel’s latest Nehalem processors, instead it’s geared against Intel’s latest quad-core Core 2 CPUs.
That’s fine for the next 9-10 months for AMD, after all Nehalem (Core i7) isn’t going to overtake Core 2 until Intel offers more mainstream platforms for it next year, but what is AMD going to do when Deneb is going up against Westmere roughly a year from now? What’s going to happen in 2010? Does AMD really expect Deneb to hold its own against Intel for two full years if they’re already acknowledging they’re behind Intel’s best 2008 processor?
What if AMD encounters delays with 32-nm and/or Orochi? Either one of these scenarios could equal major problems for the company.
From our perspective, AMD’s immediate roadmap looks fine. In terms of roadmap execution, AMD shouldn’t have any problems getting by through 2009. It’s 2010 and beyond that worries us. AMD’s best hope is for Intel to delay the introduction of their 32-nm manufacturing process or encounter some type of snag with Westmere or Sandy Bridge. If none of these occur, and Intel continues to execute on their roadmap like clockwork, 2010 could be a very rough year for AMD on the desktop space in our opinion.
On the mobile side, AMD’s refusal to offer a direct competitor to Atom is definitely intriguing. For now, AMD has no plans to offer a CPU with TDPs rivaling Atom. Instead they plan to offer notebook solutions that are slightly more expensive, and certainly more powerful. AMD wouldn’t give any specifics when it comes to price, although when pressed they implied price points starting somewhere in the $500 range with Windows Vista included. Considering that ASUS has multiple Eee PC’s priced above $500, AMD could have a winner if their partners can offer a compelling full-fledged alternative priced in that range. For their part, Intel certainly is walking a tightrope when it comes to Atom. The company enjoys Atom’s sales volume, but on the other hand its low price is hurting their ASPs (average selling price) of their CPU line overall.
With the lack of a single high-end CPU, AMD’s ASPs are already lower than Intel’s. Also remember that the company doesn’t have the engineering resources of Intel, so rather than devote their limited resources on a low-end Atom competitor, they’d much rather devote their engineers to CPUs with higher profit margins.
Considering these last two points, we don’t fault them for approaching the nascent netbook market with a healthy dose of skepticism.
In closing, hopefully AMD has learned from their mistakes of the last year and is able to turn a profit soon. With the divestment of their foundries, the company can now focus 100% on CPU/GPU design. We also hope that AMD has more products planned for 2010 than they’re currently willing to divulge. Over the course of the next year, Nehalem and follow-up parts from Intel will slowly trickle down from the high-end desktop segment to the mainstream desktop and mobile markets. When that occurs, AMD’s going to need more than Deneb and Propus on the desktop, while Intel’s lead in the mobile space could grow despite AMD’s superior graphics solutions.
