Memory Bandwidth Benchmarks

SiSoftware Sandra 2016 SP3 Memory Bandwidth: link

SiSoftware Sandra 2016 is a utility, which includes remote analysis, benchmarking and diagnostic features for PCs, servers, mobile devices and networks. This test has been popular for CPU and memory benchmarks for well over a decade and it is one of the easiest benchmarks out there to run.

AIDA64 5.80 Memory & Cache Benchmark: link

AIDA64 is an industry-leading system information tool, loved by PC enthusiasts around the world, which not only provides extremely detailed information about both hardware and installed software, but also helps users diagnose issues and offers benchmarks to measure the performance of the computer.

 

Memory Bandwidth Results Summary: The Intel Core i7-6950X and Core i7-6900K were tested on the same exact board and the Corsair Vengeance DDR4 3000MHz memory kit with CL15 timings was the same. Due to this fact, it’s not a big shocker that the memory performance being very close, but we were shocked to see that the 6900K was slower in most the tests as we weren’t sure if having more than 8-cores would really impact memory bandwidth since they were running at lower clock speeds.

    What a Crock in ALL the forums they say the 6-8 Cores are Worthless Over Kill. Unless you spend ALL day editing and want to save time then it Becomes a TAX Wright off as a Business Expense. Other wise they have NO Use. My 2500 stock Blows through All games steam and Origin Max Out. I bought a Devil Canyon for 190$ that is even Over KILL. All these Stories are Just Advertisement to SELL something you Don’t need. And if AMD is really that Good Intel WILL have to drop their Prices in HALF.

      well it’s overkill until our software becomes so complex that we need the overkill as standard.

    You’d have to be a complete idiot to buy a broadwell-E right now and not wait until Ryzen proves it’s better and/or Intel drops prices to compete

    My 3970X is holding strong. Love how my memory was supposed to be max 55gb/s and is actually running more like 62-65gb/s reads and writes. 64gb of quad channel ddr3 2400mhz is holding up just fine.

    “Both processors have 40 PCI Express lanes, so you don’t have to worry about the limitations of the Intel Core i7-6800 on Intel X99 platforms.”

    I don’t think the 28 PCI Express lanes on the Intel Core i7-6800K is a serious limitation. In SLI or crossfire, 8 PCI express lanes are enough to drive a second GPU without a bottleneck. Or you can just forget about SLI or Crossfire – a single GTX 1080 get’s the job done – even at 4K. You may have to dial back settings in the latest games – which I’ve done and the games still look great. Only in the most heavy threaded applications will you benefit from having 8 cores over 6. Those applications always make you wait…you’ll still be waiting…only waiting less. If your workload is only sometimes heavy threaded (Arguably 99+% of people on the planet) then you can save yourself another $600.

    When you compare the extra money spent versus the performance gained, the i7-6800K really shines.

      Agreed.

      And the 6800K isn’t even in the comparison charts.
      Funny how that works …

      Fake News

      • tristan smith

        “Fake News” really? is it not good to have nonsense out there that way we have to learn how to discern real from fake? correct me if i am wrong.

          ‘Triggered’ !

    Nate, thanks for the thorough review and including my 2700K at 4.5 in da mix. I can still sit tight.
