AMD talks details of "Bulldozer," the first completely new architecture since K8

AMD plans to launch its third-generation Opteron platform in 2009 with the Sandtiger octal-core processor. Beneath Sandtiger is AMD’s M-SPACE modular approach towards CPUs. M-SPACE allows AMD to mix and match CPU features for specific tasks.

The definition for M-SPACE is as follows:
  • Modular: Reconfigurable “building blocks” for design speed/agility
  • Scalable: Linear scaling of multi and single-thread performance
  • Portable: Energy-efficiency for increased mobility/portability
  • Accessible: Ongoing commitment to open innovation
  • Compatible: Backward compatibility and ease of upgrade
  • Efficient: Optimal on-chip and system level I/O efficiency
Sandtiger’s eight cores consist of eight AMD Bulldozers. Bulldozer is the name AMD has given to one of the CPU cores for its M-SPACE architecture. AMD claims dramatic performance-per-watt improvements in HPC applications with Bulldozer cores. Unlike Barcelona and Shanghai, which have evolved from AMD’s K8 architecture, Bulldozer is a completely new design developed from the ground up.

AMD installs eight Bulldozer CPU cores in Sandtiger with a memory control. AMD optimizes the design for servers and raises the performance-per-watt bar for single and multithreaded applications.

The modular M-SPACE technology also finds its way into Fusion. AMD plans to mix and match M-SPACE components for Falcon, a Fusion processor optimized for mobile and mainstream desktops. Falcon forms the basis of AMD’s planned Copperhead mainstream desktop platform. Falcon features four Bulldozer CPU cores with an integrated graphics processor. The integrated graphics processor features DirectX 10, possibly 11, support with AMD’s Universal Video Decoder, or UVD, technology. Falcon also features integrated PCIe.

In addition to Bulldozer, AMD has the Bobcat CPU core for Fusion processors designed for mobile, ultra-mobile and consumer electronics applications. Bobcat is also a completely new design and has greater power scaling capabilities. Bobcat-based processor designs can consume as low as one watt of power. AMD has not announced any details of Bobcat-powered Fusion processors yet.

Expect AMD to introduce Fusion designs based on Bulldozer and Bobcat beginning in 2009.

Practicality???

Graphics on the CPU... sounds great on paper. why not send graphics over the hyper transport bus. That would get instructions from ram to CPU/GPU incredibly fast. It doesn't seem like it would be easy to squeeze high end graphics features into such a small die that's shared with the Main CPU. If I add a Beast Graphics card (ie 8800 ultra) to a computer using this processor, what would happen to the part of the processor that's meant for graphics. would those cores just take up space and cost me money for cores that don't get used.
One might also think that this is a great idea for a laptop. Which it sorta is. but it is highly unlikely that an eight core processor has any sort of power efficiency which would deter people from this processor from most laptop buyers. I mean who wants a laptop that has 40 mins of battery life.
It actually sounds like a great Idea for server purposes. the on processor graphics would relieve bandwidth from the northbridge which is a very high traffic area for servers anyway. Most Servers aren't particularly concerned with super high end graphics and multicore processors are always a plus for servers. They're also not perticularly concerned with power consumption as much as laptops are.
It seems as though this basic design is aimed towards the server users. A basic desktop user doesn't need an 8 core processor. A high end desktop user would want to customize the graphics card. A laptop user wouldn't need 8 cores and can still achieve great performance on 2 cores which would yield better bettery life anyway.
If any AMD people are reading this. The list of consumers that this kind of processor would benefit is smaller than what I think AMD should be aiming for.
