How We Tested

In order to achieve a generic conclusion about the impact of the dual-channel technology over the integrated video performance, we decided to use two different systems, one with an AMD processor and one with an Intel CPU. Besides this, those two systems use different amounts of RAM and operating systems.

So, you must keep in mind that those tests do not compare the performance of the two CPUs (even because they have very different price points), but the impact of the dual-channel in each configuration.

During our benchmarking sessions, we used the configurations listed below.

Hardware  configuration (AMD)

Hardware configuration (Intel)

  • Processor: Core i7-5775C
  • Video: Iris Pro 6200 (integrated to the processor)
  • Motherboard: ASRock Z97 Extreme 4
  • CPU Cooler: Intel stock
  • Memory: 16 GiB DDR3, two G.Skill Sniper F3-1866C10D-16GSR 8 GiB modules configured at 1,600 MHz
  • Boot drive: Kingston HyperX Savage 480 GB
  • Video Monitor: Philips 236VL
  • Power Supply: Corsair CX500M

Operating System Configuration

  • Windows 7 Home Premium 64-bit (AMD)
  • Windows 10 Home (Intel)
  • NTFS
  • Desktop resolution: 1920 x 1080

Driver Versions

  • AMD driver version: 15.7
  • Intel driver version: 10.0

Software Used

Error Margin

We adopted a 4% error margin. Thus, differences below 4% cannot be considered relevant. In other words, products with a performance difference below 4% should be considered as having similar performance.
