Performance-Per-Watt & How The Raspberry Pi 2 + Pi Zero Compare To Old NetBurst CPUs
Written by Michael Larabel in Processors on 8 December 2015. Page 6 of 6. 10 Comments

To see more Raspberry Pi 2/Zero benchmarks, see our early Raspberry Pi Zero $5 benchmarks that compared the results to some other ARM systems too. Other ARM tests are forthcoming on Phoronix.

If you want to see how your own Linux system(s) compare to all of these other data points, simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 1512081-HA-BIGSYSTEM64.

Overall these results were interesting. In terms of raw performance, the Raspberry Pi 2 was performing in some CPU-bound tests better than the Celeron D 320 (2.4GHz) processor but in no test did a Raspberry Pi beat out the old Pentium 4 C NetBurst processor. When it came to power efficiency, the Raspberry Pi devices shined and were many times more efficient than these old Socket 478 processors. However, when comparing the results to newer Broadwell and Bay Trail processors, not only was the modern Intel hardware faster but it was also more power efficient than the two tested Raspberry Pi development boards.

If you are looking at any Pi devices, check out the Lover Pi on Amazon.com store, which was kind enough to send out a number of these low-end ARM board samples for testing at Phoronix.
