AMD64 with Direct Connect Architecture can improve overall system performance and efficiency by eliminating traditional bottlenecks inherent in legacy architectures.
Legacy front-side buses restrict and interrupt the flow of data. Slower data flow means slower system performance. Interrupted data flow means reduced system scalability.
With Direct Connect Architecture, there are no front-side buses. Instead, the processors, memory controller, and I/O are directly connected to the CPU and communicate at CPU speed.
Direct Connect Architecture is available only with AMD64 processors, including the AMD Opteron™ and AMD Athlon™ 64 processors, as well as with AMD Turion™ 64 mobile technology.
Exclusive features of Direct Connect Architecture include:
Integrated memory controller
AMD64 processors with Direct Connect Architecture feature an integrated, on-die memory controller, optimizing memory performance and bandwidth per CPU. AMD’s memory bandwidth scales with the number of processors, compared to legacy designs that scale poorly because access to main memory is limited by external Northbridge chips.
HyperTransport™ technology
HyperTransport™ technology is a high-speed, bi-directional, low latency, point-to-point communication link that provides a scalable bandwidth interconnect between computing cores, I/O subsystems, and other chipsets. AMD Opteron processors support up to three coherent HyperTransport links, yielding up to 24.0 GB/s peak bandwidth per processor.
