I'm happy to point out that a user has discovered the logic in the Skype prgram which basically descriminates agains any GPU that's not "GenuineIntel" and doesn't have at least a dual core. He then patched it and has released a downloadable patched version of the latest Skype. Everyone can now have 10-user conference calling... well, everyone using windows. No patch for the Mac version. :(
Recently, Skype and Intel have announced a deal that would limit Skype's functionality on all but specific Intel processors. Currently, Skype 2.0 offers 10-way conference calls only on Intel's latest dual-core CPUs, while other chips, including all AMD chips, will only allow for 5-way conference calls. It is argued that only those Intel dual-core CPUs meet the requirements - which would imply that no AMD CPU is fast enough.
Now, what are these requirements? Is there some kind of micro-benchmark built into Skype which measures the processing speed? Or does Skype look for a specific hidden CPU feature? As the details on the patch reveal, the code logic behind the limitation is quite simple:
If it's a CPU with 'GenuineIntel' branding and has at least two cores, then allow 10 users; else limit to 5 users.
