When AMD 64 came out it killed the P3 and P4 because of its IO enhancements. By moving the northbridge into the CPU no longer did desktop cpus feel sluggish and no longer would they lock up in IO based tasks. It was a large jump in the desktop space. (Before AMD64 copying a file on your hard drive would run your cpu at 100%. You couldn't multi task and read the news while burning a CD, and so on.)
Intel responded later with the Core 2 Duo, which not only met AMD on its playing field but beat it. For anyone who is wondering how Intel did this, here is an in depth article on the topic: https://www.anandtech.com/print/10525/ten-year-anniversary-of-core-2-duo-and-conroe-moores-law-is-dead-long-live-moores-law https://www.anandtech.com/print/10525/ten-year-anniversary-o...
- monocasa 6y agoThe northbridge absolutely would not cause your CPU to lock up on I/O based tasks, and contained an arbiter to balance CPU and I/O initiated memory requests. The CD burner issues were because they required hard real time control to not screw the disc up.
- kasabali 6y agoTo add that Core 2 (which was given as an example in the parent post) was still using the traditional north bridge design.
- proverbialbunny 6y agoThe AMD 64 did not, which is what gave it its large speed boost. https://www.anandtech.com/show/1098/6 https://www.anandtech.com/show/1098/6
