"As the well-informed colleagues of Planet3DNow! Learn, AMD will successor at K10 (we think K11) to the basic design of the AMD K6 back. Short memory or to those who are too young to recall to the K6. The AMD K6 was mid to late 90s manufactured, had one of the highest IPC (to a good efficiency per clock) of all x86 CPUs and AMD was already a big step further in the world market.
Who is now something about wondering why a man about 10 years old design again wants to be the one recalled. Intel Core2 processors are based fundamentally on the Pentium III, of course, were the latest techniques (command sets, etc.) are inserted and bottlenecks eliminated.
The big advantage of the K6 was only 6 classify long pipeline, an intelligent Branch-Predictor and then times very large TLB. After parts of the slow-speed FPU, and a very bad / slow connection to the infrastructure and bad Taktbarkeit. Therefore, the K6 also often its performance is not off, as simply too little data to the CPU came. But enough of the K6
By HT3.0, the problem with the connection already been solved and things FPU AMD has also made great progress, and problems resolved Speed Path = higher stroke. That would be the biggest weaknesses remedied, but still much to do. Of course, even at K11 new command sets (by SSE to SSE5, X86-64, etc.) to use new manufacturing processes (45nm SOI based on germanium), a 512Bit connected with, and with full CPU operated 256KB L2 cache, and 8MB L3 cache to .
Since the times of K6 from 250nm to 180nm manufacturing processes, is the number of transistors also quite small. Thus, a K11 core merely 24Mio transistors (to just 5 mm ², to come across yet IMC CPU, Northbridge, and the 8MB shared L3 cache. For comparison, a recent AMD K8 dual core with 2x 512KB cache has 184MIo transistors.Some are perhaps already on this, which I also would like to.
AMD is in a position many nuclei at K6 usual small TDP to a very small area DIE-to get. The CPU is therefore very cheap to produce and is only about 90Watt unter Volllast aller 16 Kerne benötigen. 90Watt under full load of 16 cores. A dual-core for mobile applications to be easily 10Watt coming!
This allows AMD to offer low cost many models, and a large part of the market covered. The clock rates should begin to lie about 2Ghz, later. All the fun will begin at the end of 2009. Incidentally, the new AMD core landed on the name "Bazooka". Even by the Swift M CPUs known space is used. It is also the integration of GPU cores, etc. At the conclusion that even the mention everything but still more unconfirmed rumors. However, Planet3DNow! Not really known for false reports and the information sounds realistic. And now, a comparison of the old K6 III and the planned K11, and an AMD slide."
