Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Intel to Deliver Quad-Core Mobile Processors Next Month
"We're bringing quad-core to mobile in August," said Sujan Kamran, regional marketing manager for client platforms at Intel in Singapore. Kamran declined to disclose specifics of the quad-core chip, which will carry Intel's Core 2 Extreme moniker.While the article goes on to say that quad-core "is more about bragging rights than a genuine boost in performance", Apple is working on their next revision of Mac OS X (Snow Leopard) which is expected to specifically focus on multi-core performance.
It's not clear if Apple would use such a chip in their MacBook Pros, which currently use Dual-Core mobile processors from Intel. Apple also uses the Intel's mobile processors in their iMac. The "Core 2 Extreme" version of the mobile chip typically draws more power which may prevent it from finding its way into the MacBook Pro initially.
