"Geneseo": Intel's Answer to AMD "Torrenza"

As you might know, AMD shaked the semiconductor world couple of months ago by announcing its wish to open its processor platform to third-party hardware developers thanks to a technology entitled Torrenza. Via this direct access to hardware, one will be able to install accelerators designed to speed up some specific tasks/functions/process.
Last week, during the last IDF in Beijing, Intel announced the "Geneseo" project aiming to provide an answer to AMD initiative. While AMD technology will open both Opteron socket and PCI-Express to third-parties, Intel Geneseo will only focused to the PCI-Express, becoming an additional extension of the PCIe bus. Here one can immediately spot the difference performance wise, between an accelerator connected via the Opteron socket, getting access to high-speed system bus, as well as low access time devices and low latency memory bus; and an accelerator plugged to the PCIe bus. Of course, accelerator aiming to take advantage of AMD technology will require a much deeper integration and will of course be more expensive to develop than accelerator installed via the Intel PCIe-only solution.
So in 2009, one will be able to evaluate if the strategy of high-cost/high performance accelerator was more suited than the cheap/universal PCIe way.
