Performance, benchmarks and gaming
One of the big criticisms of the current MacBook Air platform is that it uses Core 2 Duo chips at its core. Taking a step back, however, it appears to be a pretty reasonable decision. Until Intel’s Sandy Bridge platform rolls around (presumably), the integrated graphics offered by the chipmaker are…less than stellar.
Unfortunately, the thermal envelope of the MacBook Air is unable to support both integrated and discrete graphics – a necessity if Apple had chosen something like the Core i3-330UM. Using the NVIDIA MCP89 chipset and associated GeForce 320M graphics, (a custom part for Apple based on the more powerful GeForce 335M found in laptops like the M11x) Apple is able to get respectable graphics performance and adequate battery life while maintaining the MBA’s profile.
Even though the Core 2 Duo SU9400 is only clocked at 1.4GHz, it remains a surprisingly robust platform capable of handling some complex tasks.
