Moving From Intel Ivy Bridge 3770K to Intel Broadwell 5775C

Some Quick Ivy Bridge Versus Broadwell Benchmarks


Our old Intel Ivy Bridge platform scored a 6.5 base score in the Windows Experience Index in Windows 7 and the lowest score was the Graphics component in the test.



On the new Intel Broadwell platform we scored a 7.4 base score thanks to the improved Graphics performance in Broadwell. None of the other subscores changed.

We ran 3DMark Sky Diver on both systems and got an overall score of 2,266 on the Intel Core i7-3770K system with a graphics score of 1,966 and a Physics score of 10,201.


On the new Intel Core i7-5775C system we scored 6,670 on Sky Diver with a graphics sub-score of 6,243 and an overall physics score of 10,968. As you can see the Broadwell system with Intel Iris Pro Graphics 6200 is getting the bulk of the performance gains from improved graphics.


Here are the results from the Core i7-3770K system. As you can see we were getting around 27,000 to 28,000 MB/s speeds and had a latency of 47.1 ns.


The latest version of AIDA64 is not optimized for Broadwell and a warning pops up stating this as soon as the benchmark completes. The read/write/copy benchmarks are all higher than Ivy Bridge, but the latency is much higher at 59.6 ns. Both systems were tested with the same exact memory kit!


We next wanted to run 4K (3840×2160) video editing tests, so we downloaded HandBrake 0.10.2 and converted our 5.00GB 4K MOV clip from our GoPro camera to an MP4.



The Intel Broadwell platform had a 15.8% higher average frame rate and we were able to complete the workload just over six minutes faster!


Next we used that same 4K 5.00GB movie clip and used CyberLink MediaEspresso 7 with Intel QuickSync video enabled (hardware encoding and decoding) to convert the file to the Apple iPhone 6 Plus with the better quality profile.


When Intel QuickSync video is used you’ll see a massive 38% reduction in conversion time from our Intel Ivy Bridge platform and the new Intel Broadwell platform! If you are running software that uses Intel QuickSync, you should see nice performance gains over older processors!


Testing a 3-year old Kingston HyperX 5K 480GB SATA SSD versus a brand new HyperX Predator 480GB M.2 PCIe SSD that just had Windows 7 and our base applications installed on it for a week feels wrong, but it shows real world performance on systems that have been used. The sequential and random write performance saw the largest performance increases, but most all of the read tests also improved. We were a bit shocked to see the 4K QD32 test actually lower on the new drive, but we ran the benchmark multiple times and the results were constant.


Here is a look at the performance on the HyperX Predator 480GB M.2 PCIe SSD right after we installed Windows 7 Ultimate 64-bit and all 251 Windows Updates that are needed! Most of these performance numbers are higher than our week old drive numbers shown above and we are showing this to show the difference between a ‘fresh’ and ‘used’ SSD.


We ran a quick Gigabit LAN test to set out the performance on new Intel I218V controller and was happy to see we were hitting 112.3 MB/s on our office network that uses Netgear switches. Not bad considering the theoretical limit of a Gigabit network is 125 MB/s and we all know theoretical speed limits are seldom actually obtained in the real world due to network overhead.

Let’s take a look at Power Consumption and Tempeartures!

  • actually the very best gaming cpu on the planet still when paired with a 1080ti or Titan Xp. Boy, did you guys ever goof this one up!
    Or, more likely were paid by Intel to sabotage this awesome gaming cpu. WHAT a shill.

    Oddly enough, 6 months later and they all did make high end DDR3L kits, up to at least 2133 from Corsair. They’re more expensive at the moment than the DDR4 kits… so their point is kind of moot except for those who are still on older systems and want the low voltage for a later incremental upgrade, but if prices and availability are any indication, they’re going to not be available for much longer.

    Love the hate people give. Other people spend money and give you a review for free and you have a negative comment. If Legit Reviews want to spend $1330 on a new office computer , then they can. Obviously they are after the Iris Pro and not a dGPU. I wish people could keep their stinking negative opinions to themselves. One thing wrong with this world, too many ****ing opinions.

  • MoogleStiltzkin

    also though you specifically mention this was a case scenario from ivy bridge 3770k to a broadwell, though interesting, it would also be nice if you had made a 2nd scenario for a more typical gamer user.

    the integrated graphics doesn’t do much for gamers. so skylakes lack of isn’t really an issue. also like ano mentions it’s better anyway.

    $1330 for ~10% improvement, or get a dedicated graphics card for $300 and a 500% improvement in the graphics performance. Your conclusion should have stated, take the G card option, upgrading anything else would be the behavior of a madman – utterly pointless.

      Obviously you can read, maybe you’re just too dense to read it all… This machine is for office drone duty. Why would you need a $300 GPU to run office apps?

      • Virtual Insanity

        I agree with the $1330 for 10%
        The article only states that the ability to drive a 4K display was the only real thing lacking.
        An $80 discrete graphics card would have done the job.
        i7 and water cooling for what is admitted to be an office machine?

        Efficiency counts for more than just watts of power drawn from the wall.
        Superfluous upgrading is far from efficient, encouraging the manufacture of goods unnecessarily.

        Appreciate the content, but feel the point is lost, not sure what is trying to be achieved.
