AMD Launches New FX CPUs, Cuts Prices On Existing Processors

With John The Ripper, the FX-8370 was running around the same speed of the FX-8350 that in turn competed well with the Core i7 4770K for this particular benchmark while the FX-8370E with its lower base frequency led to lower numbers. The FX-9590 was running into an issue still being investigated. (AMD CPUs tend to run nicely with John The Ripper.)

The AC system power monitoring was done with a USB-based WattsUp Pro power meter that was automatically polled by the Phoronix Test Suite. The FX-8370E had an average power draw of 165 Watts while the FX-8370 came in at 203 Watts. The FX-9590 meanwhile had an average draw of 241 Watts with a peak of 391 Watts. The FX-8370 system power draw was close to that of the Core i7 4960X.

On a performance-per-Watt basis, the FX-8370/8370E came in at close to the same value. (The Core i3 4130 results are missing from the power testing due to a simple oversight and not having the time to run those numbers for the power result file prior to the NDA expiration time.) The FX-8350 proved to be more power efficient for JTR performance than the newest FX CPUs.
