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:

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.

    Thankfully the comments of a certain troll were removed so mine no longer makes sense, for any future readers. Reply

    Just like how overclocking a Pentium 4 resulted in it beating an Athlon 64 and had lower power consumption to boot-- oh wait. Reply

    That's a stupid comment only a stupid fanboy would make AMD is way ahead of Intel in the graphics department and is very competitive with Intel in the mobile segment now. Reply

    Your comments would do nothing to inform regular readers of sites like this, we already know more. So please, can it. Reply

    Not what I asked little troll. Give a source that says Apple will get a special HD4000 like no other. Reply

    What are you talking about? As long as AMD has a better iGPU there is plenty of reason for them to be viable choice today. And if gaming iGPU performance holds on against Intel there is more than just hope of them getting back in the game in terms of high performance comput tomorrow. Reply

    I'm pretty sure even 16x AF has a sub 2% performance hit on even the lowest end of todays GPUs, is it different with the HD Graphics? If not, why not just enable it like most people would, even on something like a 4670 I max out AF without thinking twice about it, AA still hurts performance though. Reply

    AF has greater performance impact on low end GPUs. Typically its about 10-15%. It's less on the HD Graphics 3000, only because their 16x AF really only works at much lower levels. It's akin to having option for 1280x1024 resolution, but performing like 1024x768 because it looks like the latter.

    If Ivy Bridge improved AF quality to be on par with AMD/Nvidia, performance loss should be similar as well.

    Hmm I did not know that, what component of the GPU is involved in that performance hit (shaders, ROPs, etc)? My card is fairly low end and 16x AF performs nearly no different than 0x. Reply

    AF requires more samples in cases of high anisotropy so I guess the TMU load increases, which may also increase bandwidth requirements since it could force higher LOD in these cases. You'll only see a performance difference if the AF causes the scene to be TMU/bandwidth limited instead of say, ALU limited. I'd expect this to happen more as you move up in performance, not down, since ALU:TEX ratio tends to go up along the higher end.. but APUs can be more bandwidth sensitive and I think Intel's IGPs never had a lot of TMUs.

    Of course it's also very scene dependent. And maybe an inferior AF implementation could end up sampling more than a better one.
