Testing Procedures

Our testing procedures are used to determine the performance and energy efficiency of the CPU and its integrated graphics (if applicable). A series of CPU and GPU-centric benchmarks are used and system power consumption is measured in various states as well as during each CPU benchmark (an average of the first 5~15 seconds).

CPU testing is conducted with a discrete graphics card (a GeForce 9400 GT) to eliminate integrated graphics as a variable, most notably with regards to power consumption. This is necessary to fairly compare CPUs that do not have an onboard graphics chip such as AMD FX/Athlon and Intel "E" models. Default CPU core clock speeds/multipliers are used rather than those prescribed by the motherboard manufacturers.

Measurement and Analysis Tools:

Video Test Suite:

H.264/MKV 1080p: A custom 1080p H.264 encoded clip inside an Matroska container with a 22 mbps bitrate.

YouTube HTML5 4K: RBG Rainbow, a dead/stuck pixel screen fixer in 4K.


GPU Benchmark Suite:

Gaming tests are conducted at two resolutions, 1366x768 and 1600x900 (or the closest allowable screen resolution) with differing levels of image quality. The results we report are for the highest resolution and detail level with which the product can deliver a reasonably good framerate (about 45 frames per second).

CPU Benchmark Suite:

  • Adobe Photoshop: Timed image processing job; A derivation of Driver Heaven's Photoshop Benchmark V3.
  • foobar2000: Timed audio (FLAC) encode.
  • Windows Defender: Timed anti-virus scan.
  • 7-Zip: Timed file compression.
  • TrueCrypt: Encryption/decryption benchmark; 500MB setting, AES-Twofish-Serpent algorithm, mean result, converted into time for comparison purposes.
  • HandBrake: Timed video (H.264) encode.
  • Maxon Cinebench: Rendering benchmark; CPU setting, converted into time for comparison purposes.

As we will be making conclusions on the energy efficiency of the CPUs compared, some of the power consumption figures have been artificially adjusted to be more "average" to better represent typical energy efficiency. This particularly applies to the Intel Core i7/i5 processor results as they were tested on the Gigabyte Z170X-UD5 and Gigabyte Z97MX-Gaming 5, two unusually energy efficient motherboards according to our extensive power consumption tests of LGA1151 and LGA1150 boards.

Our timed benchmark results have also been adjusted but proportionally (such that relative differences remain the same) to facilitate better chart scaling.
