Intel Pentium G3258 On Linux
For making these Linux tests of the Intel Pentium G3258 interesting, I compared the performance of this dual-core CPU to the other following Haswell parts:
- Intel Core i3 4130
- Intel Core i5 4670
- Intel Core i7 4770K
- Intel Core i7 4790K
The selection was limited to the on-hand Haswell CPUs I had available. When benchmarking the G3258, I ran our large selection of benchmarks on the CPU at its stock frequency (3.2GHz), overclocked to 4.0GHz, and lastly at 4.4GHz as the maximum stable frequency achieved for this configuration.
All the CPUs were tested from the ASRock Z97 Extreme6 setup while running a clean Ubuntu 14.10 daily installation with Mesa 10.2.3, GCC 4.8.3, Unity 7.2.0, and then manually upgrading to a recent snapshot of the Linux 3.16 kernel. The benchmarks are on the following pages. Following the raw Linux performance results are also some power consumption and performance-per-Watt numbers. Unfortunately I don't have any thermal readings to report since the coretemp Linux kernel driver hadn't detected the CPU for reading its temperatures under Linux.
All benchmarking was carried out via our enterprise-used, open-source Phoronix Test Suite benchmarking software with OpenBenchmarking.org.
