Compression & Encryption Performance

7-Zip Benchmark

By working with a small dataset, the 7-zip benchmark gives us an indication of multithreaded integer performance without being IO limited:

Although real world compression/decompression tests can be heavily influenced by disk IO, the CPU does play a significant role. Here we're showing a 15% increase in performance over the 2600K. In the real world you'd see something much smaller as workloads aren't always so well threaded. The results here do have implications for other heavily compute bound integer workloads however.

TrueCrypt Benchmark

TrueCrypt is a very popular encryption package that offers full AES-NI support. The application also features a built-in encryption benchmark that we can use to measure CPU performance:

AES-128 Performance - TrueCrypt 7.1 Benchmark

Our TrueCrypt test scales fairly well with clock speed, I suspect what we're seeing here might be due in part to Ivy's ability to maintain higher multi-core turbo frequencies despite having similar max turbo frequencies to Sandy Bridge.

    How long will Intel keep its HD Graphics increases? Reply

    I don't understand the logic of selling a high end CPU with the best IGP. Seems like anyone running an it isn't going to stick with the IGP for games, and if they aren't gaming, then what good is that high-end GPU? Maybe the entire "Core i" line should use the HD 4000. Reply

    Because the low end chips are just die-harvested high end chips it makes sense. No reason to disable it so they leave it on.

    And some people do actually use high end processors with IGPs. It's fairly easy to get one from a major OEM. It's stupid but most people don't know any better.

    Funny comments I saw.

    What's wrong even if the High End CPU that comes with IGP?

    Is High End CPU = Gaming Machine CPU? If that is your logic, you're a rich but shallow boy!

    I do lots of Video Editing and Transcoding, I need High End CPU but None of the High End GPU beats Quick Sync in Transcoding in terms of Quality and Speed.

    "and if they aren't gaming, then what good is that high-end GPU?"

    I feel like you missed that part. He's not saying that only gamers use high-end CPUs. He's saying that gamers using a high-end CPU won't care about the high-end iGPU because they won't use it. Also, non-gamers who need a high-end CPU generally won't see the benefits of the included high-end iGPU. So, he proposes that the better niche for the high-end iGPU would be on the more affordable CPUs, because then budget-minded gamers could buy an affordable CPU that has a relatively powerful iGPU integrated into it.

    This is a mid-range CPU, not high-end one.

    High desktop CPUs (i7 3800-3900) don't have IGP.

    It is because laptops continue to get slimmer and slimmer. Getting good GPU performance without the compromises on the chassis that a dedicated GPU would force is the point. Reply

    This.

    My next laptop will have processor graphics for the sake of battery life and size, and whoever has the best graphics gets my money.

    If the 4000HD is on the level of lets say a 560m I would not hesitate to get a laptop with no dedicated graphics but if it isn't I'm still going to go for the dedicated. Reply
