Intel Core i7 4790K: Devil's Canyon Benchmarks On Ubuntu Linux

Written by Michael Larabel in Processors on 11 June 2014. Page 6 of 6. 16 Comments

Reports so far of the Core i7 4790K overclocking in the real-world have been good, while I'll be experimenting with some overclocking on air-cooling in the days ahead once I've had more time with the review sample.

While running a few benchmarks and measuring the AC power consumption of the system using a WattsUp power meter logged by the Phoronix Test Suite, the i7-4790K configuration had an average power draw of 86.3 Watts compared to 70.6 Watts for the i7-4770K. The peak power consumption of the i7-4790K was much greater at 215 Watts versus 130 Watts for the i7-4770K, but only in a few rare cases did the power peak that high.

For performance junkies, the Core i7 4790K is currently the best desktop offering Intel has until desktop Broadwell CPUs make it out months down the road. With AMD having no serious high-end desktop processors, the i7-4790K is easy to call a winner. The i7-4790K is a nice upgrade if you're currently running a Sandy Bridge or Ivy Bridge CPU, since its price is about $340 USD at launch, which is right around the original price of the i7-4770K (currently the i7-4770K can be found for ~$310) while offering ~10% better performance than the i7-4770K in computational workloads.

Overclocking results and many other Linux (and perhaps BSD too) performance numbers for the Core i7 4790K will be coming out shortly on Phoronix due to just having had the processor for a few days. Thanks to Intel for the Devil's Canyon review sample for being able to inform Linux users about the support and performance.

Thanks to the open-source Phoronix Test Suite and, if you wish to see how your own system's Linux performance compares to this range of Intel Haswell CPUs and the AMD FX-8350, it's actually rather trivial and quite easy to compare. Simply install the Phoronix Test Suite on your system and then run phoronix-test-suite benchmark 1406101-KH-INTELDEVI74 to automatically download/install all the tests that were run for this article, set them up in the same configuration as we used for testing, and then the Phoronix Test Suite will continue to automatically run all the tests and end with comparing all of the data side-by-side. It's that easy! Give it a shot and share your results with us on
