Bulldozer memory controller will be fully enhanced

AMD continues to elaborate bulldozer processor architecture in the form of a question and answer on the official blog, which again referred to the memory controller.

John Fruehe, director of marketing for AMD's server and workstation products, said: "Our memory controllers will be enhanced. It is not convenient to talk about them, but we expect to help reduce the memory access time, both locally and remotely. As for the century Memory access time, I will stay until the time of publication."

Relatively speaking, the memory controller design is more important for server applications. This previous-generation six-core AMD Opteron server processor required two hops in a four-way configuration to find the required information in memory and had to add HT Assist assist technology. Now the Opteron 4000/6000 series is improved by the HT bus with only one Jumping, it looks like the next generation of local memory access will also be accelerated.

In addition, AMD currently uses four-channel DDR3 memory in server products, with 8-12 cores. The next generation of bulldozers will still be up to four channels, and the number of cores will increase to up to 16, but the desktop version is still dual-channel, and the core is also Up to 8

John Fruehe also said that the future will not continue to introduce dual-platform platforms in the desktop area, because now the number of cores of a single processor is already enough, dual configuration is no longer necessary, and this system is only suitable for the field of servers and workstations, the desktop market The upper share is extremely limited, with 0.8% at the highest, and only 0.4% in the fourth quarter of last year.
