Miscellanea

  • Thunderbolt supports other Thunderbolt compatible peripherals as well, providing up to 10 Gbps of bandwidth in both directions.
  • The top feature of Sandy Bridge is that the chip tries to boost up to its max speed under a heavy workload. It actually allows the chip to exceed the max value for a short duration.
  • In stress-tests CPU showed no throttling at 94-97°C but only for short spikes. Fans power is still inadequate to the heating.
  • Yet, MacBook Air Thunderbolt users are restricted in peripherals options, for they have to look for thunderbolt-compatible gadgets only. The only external display to go with would be Apple Thunderbolt, which also quite expensive.
