Hardware specialists over at Bare Feats ran a series of interesting Final Cut Pro X benchmarks pitting the latest Sandy Bridge-equipped iMac and MacBook Pro against the last year’s Mac Pro. The iMac system rocked a 3.4GHz quad-core Core i7 processor with 16GB of DDR3 1333MHz RAM and AMD Radeon HD 6970M graphics with 2GB of GDDR5 video memory. The MacBook Pro was a 2.3GHz quad-core Core i7 system with 8G of DDR3 1333MHz RAM and AMD Radeon HD 6750M graphics with 1G of GDDR5 video memory. The 2010 Mac Pro desktop had a 3.33GHz six-core Westmere processor with 24GB of ECC DDR3 1333MHz RAM and AMD Radeon HD 5870 graphics with 1G of GDDR5 video memory.
Summing up, in two out of four benchmarks involving blur sharpen and blur directional effects the iMac came in first and the MacBook Pro outperformed or matched the Mac Pro. It is in the remaining two GPU-intensive tests – exporting a Final Cut Pro X project in H.264 (transcoding) and encoding a Blu-Ray stream in Compressor 4 – that the Mac Pro shined. Although the benchmarks are far from conclusive, they give away the false impression of Apple favoring the newer Sandy Bridge architecture.
