Intel DZ77GA-70K Motherboard Benchmark Performance Tests

Manufacturer: Intel Corporation
Model Number: DZ77GA-70K
Product Name: Intel Z77 Express motherboard
Price: $224.00-$240.00 MSRP

Full Disclosure: Intel Corporation provided the product sample used in this article.

Does Intel really want to cater to enthusiasts? Personally, I've never known anyone who used an Intel motherboard in their rig, although I'm sure some people do. And it's hard to blame them: historically, third party vendors have offered superior performance and features. Intel seemed to be more concerned with stuff like skull logos whose eyes blinked as drive activity indicators rather than creating motherboards enthusiasts would actually want to use.


Here's a preview: while Intel still has a way to go to before the likes of ASUS, MSI, and EVGA need to start worrying, their latest Extreme series motherboard is the first one I've tested that's actually competitive in features and performance. In one specific area it's better than anything I've seen before.

Testing Methodology and Specifications

I was fortunate enough to have three new Intel Z77 Express motherboards available: the MSI Z77A-GD65 that I've previously reviewed, an ASUS P8Z77-V Deluxe, and the subject of this performance comparison, the Intel DZ77GA-70K.

I compared the performance of the motherboards at stock speeds using the benchmark programs listed below, with a spiffy new Ivy Bridge Core i7-3770K CPU. Since the Core i7-3770K's "HD 4000" integrated graphics shares L3 cache and memory bandwidth with the CPU cores, I disabled it and use and AMD Radeon HD5770 video card for all benchmarks. I used the same processor, hard disk, and memory on each motherboard, so that the motherboards were the only thing that changed between tests. Any performance differences at stock clock speeds are thus due to the motherboards.

On the Intel motherboard, I also ran the benchmarks at the highest overclock I could achieve.

# 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.
