Intel DZ77GA-70K Conclusion

PCMark 7 Tests

PCMark 7 is Futuremark's successor to PCMark Vantage. The full suite of tests comprises seven different sequences with more than 25 sub-tests that exercise your system's abilities in storage, computation, image and video manipulation, web browsing and gaming. It was developed with input from the designers, engineers and product managers at AMD, Compal, Dell, Hitachi GST, HP, Intel, NVIDIA, Samsung, Seagate, Western Digital and many other well-known companies.

For this benchmark I chose the PCMark test, which provides a number indicating total system performance, as well as the Productivity, Creativity, and Computation test suites.

Productivity Test

The Productivity test is a collection of workloads that measure system performance in typical productivity scenarios. Individual workloads include loading web pages and using home office applications. At the end of the benchmark run the system is given a Productivity test score. The Productivity test consists of:

  • Storage
  • Windows Defender
  • Starting applications
  • Web browsing and decrypting
  • Productivity
  • Data decryption
  • Text editing

Creativity Test

The Creativity test contains a collection of workloads to measure the system performance in typical creativity scenarios. Individual tests include viewing, editing, transcoding and storing photos and videos. At the end of the benchmark run the system is given a Creativity test score.

  • Storage
  • importing pictures
  • video editing
  • Image manipulation
  • Video transcoding - high quality

Computation Test

The Computation test contains a collection of workloads that isolate the computation performance of the system. At the end of the benchmark run the system is given a Computation test score.

  • Video transcoding - downscaling
  • Video transcoding - high quality
  • Image manipulation

It's important to note that since PCMark 7 was designed as a system test, the scores are dependent on the configuration of the entire system being tested, including things like the memory, hard disk, and graphics cards used: it's not an isolated test like most of the other benchmarks I'm using in this review. However, since all other hardware (CPU, video card, memory, hard disk, etc.) was identical, with only the motherboards being changed, any performance differences here can be attributed to differences in motherboard performance.

Except in the Computation section, overclocking doesn't help the scores that much. It does boost the Creativity score by 9%, but that won't be noticeable outside benchmark use. But in Computation, we get a nice 28% boost. At stock clock speeds, the Intel board wins only the Creativity section, but the largest difference between it and the ASUS P8Z77-V Deluxe is only about 4%.

In the next section I run everyone's favorite benchmark: CINEBENCH!



# PCI slots are still industry standardOlin Coles 2012-05-07 16:08
Conclusion ratings are purely opionion, but I think most people are still buying/using PCI-bus hardware.

And a lot of people are still running Windows XP.

This is an enthusiast-level motherboard -- save the PCI slots for the low-end stuff.

Hi! Great review but I have one question that I didn't see answered anywhere: How long does this board take to POST? By POST I mean the time it takes to go from power button pressed to Windows load screen popping up. This is information a lot of people are interested in, but I rarely see it in reviews (in fact only Anandtech test this, AFAIK).

There are several reasons you don't see this metric:

1. Most people only boot their systems once a day, if that, and the time spent to get to the Windows desktop is insignificant compared to the time the computer's being used.

2. The time will vary greatly depending on the boot device (regular hard disk, Velociraptor, SSD); the version of Windows being booted, drivers, etc.

Granted, you could use a standard hardware configuration and Windows installation to reduce the number of variables in #2, but I don't think that many people would find it useful. FWIW I didn't notice the board being particularly speedy or slow.

Thanks for the reply David! Whilst it's true that most people only boot up their system once per day (in fact I only do it twice) I can guarantee you that the average person cares more about how long their machine takes to boot up than some slight differences in benchmarks that are never actually felt by the end-user.

For reference try googling it and see dozens and dozens (hundreds even?) of people on tech forums around the world trying to find this information out :).

Or head over to anandtech and see how almost all of the positive comments mention POST time benchmarking as a great review feature.

As to hardware variability, I would assume by now that any enthusiast knows that overall boot time is greatly effected by hardware, most notably HDD/SSD. However POST time can still make 20 seconds of difference in startup time, considering most machines with SSDs start up in well under a minute, you can see how a lot of everyday users would like to see how they could shave most of this time off.

Once again, thank-you for the great review and for the reply :).

The problem with this question is that boot up time has too many variables that are far more dependent on configuration and other hardware. Did you enable RAID? Well, there's a controller that must be loaded. What boot order and devices did you enable? It may have to check for USB devices. Is RAM test enabled? Quick or full? How much? What operation system, boot loader, drivers, and services?

If you want a fast bootup: you should disable all of the motherboard features you don't use, use a small and fast boot device like a SSD without RAID, and don't install drivers and services unless you absolutely need it.
