Futuremark's PCMark 7 is a whole-system benchmarking suite. It has specific application performance measurements targeted for a Windows 7 environment and uses trace-based metrics to gauge relative performance (It has also been updated for Windows 8 compatibility). Below is what Futuremark says is incorporated into the PCMark suite...

Futuremark PCMark 7

General Application and Multimedia Performance

The PCMark test is a collection of workloads that measure system performance during typical desktop usage. This is the most important test since it returns the official PCMark score for the system
Storage
Windows Defender
Importing pictures
Gaming
Video Playback and transcoding
Graphics
DirectX
Image manipulation

Despite its lower clocks, the Core i7-5775C pulls out ahead of all of the other platforms here, mostly due to the performance impact of its 128GB of eDRAM cache and its much faster graphics engine.

PCMark 8 v2

System Level Benchmark

PCMark 8 v2 is the latest version in Futuremark’s series of popular PC benchmarking tools. It is designed to test the performance of all types of systems, from tablets to desktops. PCMark 8 offers five separate benchmark tests--plus battery life testing—to help consumers find the devices that offer the perfect combination of efficiency and performance for their particular use case. This latest version of the suite improve the Home, Creative and Work benchmarks with new tests using popular open source applications for image processing, video editing and spreadsheets. A wide variety of workloads have also been added to the Work benchmark to better reflect the way PCs are used in enterprise environments.

These tests can be run with our without OpenCL acceleration. We chose to run with OpenCL acceleration enabled to leverage all of the platforms’ CPU and GPU compute resources…

We have a different pool of reference data for the PCMark 8 tests, but as you can see, the Core i7-5775C's margins of victory in the two PCMark 8 tests we ran were much smaller. The Core i7-4770R has a similar eDRAM setup but with previous generation Iris Pro 5200 series graphics.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
