The Inquirer reports AMD is planning to integrate PCI Express onto its Opteron processors with Socket F. This will mean another serious decrease of latency and everything from graphics cards to 10 Gigabit Ethernet would get faster.
For the home, you get more frames and better graphics responsiveness. For the business world, you get latency reduction on I/O, latency reduction on I/O, and latency reduction on I/O as the three most important things.
The Inquirer says this is a clear win for AMD, when it will come out.
If you were wondering what all those pins on S1207 were for, wonder no more. If you need I/O that scales with the number of CPUs, look no farther.
The AMD Athlon 64 already integrated the memory controller onto its chips and Intel will do the same soon.
