Intel Core i7 4770K "Haswell" Benchmarks On Ubuntu Linux

Starting was Rodinia, a scientific benchmark commonly used within academia settings, and the OpenMP LavaMD workload. The Core i7 4770K was about 12% faster than the Core i7 3770K "Ivy Bridge" processor and was significantly faster than the AMD FX-8350.

With the OpenMP Leukocyte workload, the i7-4770K was still faster than the i7-3770K, but the FX-8350 had a surprising showing and came out ahead. This isn't too much of an incredible surprise as in some select multi-core scientific benchmarks, we've seen AMD CPUs have a strong showing under Linux.

As talked about already in this article and last weekend's piece, the Core i7 4770K performance seemed to struggle at some times, possibly due to power-management/scaling or scheduling issues. Those issues are still being investigated. One CPU case where the performance was odd was with BT.A where the i7-4770K was outperformed by the i7-3770K and FX-8350.

With NASA's NPB "Embarrassingly Parallel" workload test, the Core i7 4770K was significantly faster than all tested CPUs.
