    Default CAM Benchmarking, DDR4 vs DDR3, more cores, cooling, etc

    We wrote a new blog post running some CAM benchmarks. Checking in a casual way, new memory standards vs older, does cooling matter, etc.

    I hope you find the information useful

    I seriously doubt that the 22% speed increase has very much to do with the DDR4 memory.
    It's really almost impossible to compare DDR3 vs DDR4 on an even level, as nearly all other components will be different as well.

    When I built a new PC a year ago, the general consensus was that DDR4 is certainly faster, but in the real world, you probably wouldn't notice the difference. At the time the price difference was more than double.

    I went with the DDR4 platform because of the affordable 6 core processor, not because of the DDR4. It's nice to see 12 cores (with hyperthreading) running at 100%.

    Well, for one, DDR4 is a lot faster than DD3, even with the higher latency rating. Also the memory bus is a lot wider with DDR4/Skylake than DDR3. Plus it's lower voltage, so lower thermal displacement.

    I should note my new Precision 7510 laptop is a Core i7-6820 with 16GB DDR4-2133, 4GB NVidia Quadro M2000M, 256GB NVMe SSD, and even driving a 4K screen it is stupid fast. Makes my M6500 feel like a turd, though it's still pretty snappy 5 years old.

    Yes, but memory alone is not going to increase your PC's speed by 22%. And they are used on totally different platforms, so how do you do an even comparison?

    And fwiw, my new Dell 7559, with i7-6700HQ, 16Gb DDR3, GTX960M, and M2 SSD is also pretty fast, and was only $900. Pretty good bang for the buck. Runs Fusion 360 very well.

    My 6 core desktop with 32Gb of DDR4 is not noticeably faster than the 4 core laptop with 16Gb of DDR3, unless you were to max out the laptops CPU and GPU.

    Of course, it's always difficult to make an apples to apples comparison. Even the Haswell CPU is built on a 22nm process and the Skylake on 14nm, so the electrical "passages" are shorter as well. The memory bus in Skylake is wider as well, but even with today's software it would be difficult to saturate that bus. Good future-proofing, as Skylake supports Thunderbolt 3, and uses 4 PCIe lanes for the NVMe M.2 port. So likely with today's software (I'm demoing SpaceClaim which is still only DX9) there won't be as much a performance boost. But by the fall with NVidia Pascal coming out it may be a different game.

    Pretty good price on that 7559. I was going to build a desktop workstation but I'm not home half the time and I don't want to lug my desktop around with me, or have to constantly synch up my files. Also it's nice to take my machine to a client and make changes to something right there and then. I buy a new machine every 4-5 years...

    Bought it refurbished on Ebay (Like new with warranty) for $780, and added the 16Gb of RAM and SSD myself. It came with 8Gb and a 1Tb hard drive (slow).
    I'm the opposite. I only use the laptop when I'm traveling. My old one was unbearable the last time I went away for the weekend, which made me pull the trigger on this one.
    And I upgrade every 7 years or so. I spent a lot on the Haswell E last year to get as much life out of it that I could.

    While it is nice to see benchies, I would have been quite surprised to see slower marks attributed to DDR4, As others have stated, it is difficult to compare DDR3 to DDR4 due to the differences in motherboard components and architecture. .
