As CPU speeds increased over time, a bottleneck eventually emerged between the processor and the motherboard, due to limitations caused by data transmission between the CPU and its support chipset.[7] Accordingly, starting with the AMD Athlon64 series CPUs (based on the Opteron), a new architecture was used where some functions of the north- and southbridge chips were moved to the CPU. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent.
