Bethesda's epic sword & magic game The Elder Scrolls V: Skyrim is our RPG of choice for benchmarking. It's altogether a good CPU benchmark thanks to its complex scripting and AI, but it also can end up pushing a large number of fairly complex models and effects at once. This is a DX9 game so it isn't utilizing any of IVB's new DX11 functionality, but it can still be a demanding game.

Ivy Bridge does very well in Skyrim, not able to reach 60 fps but still above 30 at up to 1680 x 1050. The gains over Sandy Bridge are significant at nearly 50%. Meanwhile Ivy Bridge also gets surprisingly close to Llano, bringing the gap down to 10% at 1366 and 18% at 1680. Seeing as how Skyrim is not particularly shader heavy at these settings, Ivy Bridge looks to be largely shrugging off its biggest bottleneck here in favor of pure pixel pushing power.

    I would like to start using quicksync, but 2 mbps for a tablet is way too much for me. I just want to quickly take a video and transcode it. There is nothing quick about copying a 1+ gigabyte file onto a tablet or phone. It does no good to be able to transcode faster than you can even copy it LOL. Can quicksync go lower? I want no more than 800 kbps,400-600 ideally.

    Also, is it possible to transcode and copy at the same time? Is anyone doing that?

    When you mention "2 mbps," I think you are referring to the bitrate, which is generally synonymous with the quality of the encoding.

    "It does no good to be able to transcode faster than you can even copy" <---I think this is completely false. The transcoding is a separate file conversion step that creates the final version which you will move to your device. Your machine won't even start copying until transcoding is complete, which means that every little bit of speed you can add to the transcoding process will directly reduce the amount of time it takes to get your file on your device.

    Getting quicksync will make a huge difference for your encoding.

    "Features like VT-d and Intel TXT are once again reserved for regular, non-K-series parts alone."

    Why do they keep doing that?

    Because those are mostly for business users, and business users don't overclock and thus don't need K-series. Reply

    I have a feeling that the real reason is that, if business users could get those features on a K-series processor, it would largely obviate the need/demand for SB-E. A 2600K/2700K overclocked up to, say, 4.5 GHz--which seems consistently achievable, even conservative--would compare very favorably to the 3930K, given the prices of both.

    Yes, I know you can overclock the 3930K, and yes, I know it has six cores and four memory controllers and more cache. But I bet that overclocked SB or IB with VT-d, &c., would make a lot of sense for a lot of applications, given price/performance considerations.

    I'd be very interested in seeing overclocked 2500K and 2600K benchmarks tossed in, because lets be honest, one of those is the most popular CPU at the high end right now, and anyone with one has bumped it to at least 4.3GHz, often about 4.4-4.5.

    I think it would be nice to have a visual aid to see how that fares, but I understand the impracticality of doing so.

    Thank you for including this section, it is great. I think it would be more relevant for people though if it were a much smaller test. I think pretty much anyone is going to know that a project of that size is going to be faster with more cores and speed. What isn't so obvious though are smaller projects, where you are compiling only a few files and debugging. A typical cycle for almost all developers is: making changes, compiling, debugging to test them out. Even though you are only talking times of a few seconds, add this up to 100s-1000s of iterations per day and it makes a difference, I base my entire computer hardware selection around this workflow. For now I use the single threaded benchmarks you post as a guide. Reply

    The features table has put me in a great dilemma. I'm very much interested in running multiple virtual machines on my desktop, for debugging and testing purposes. Although I won't be running these virtual boxes 24x7, it would be great to have processor support for any kind of hardware acceleration that I can get, whenever I fire up these for testing. On the other hand, ability to overclock the K series processor is really tempting, and yes, a decent/modest overclock of say, 4.2-4.5GHz sounds lovely for 24x7 use.

    Anyone using SNB/Intel processors with VT-d can share if its worth going for non-K processor to get better virtualization performance? To be more clear, my primary job involves web-application development with UX development. For which I require a varied testing under different browsers. Currently I've setup 4 different virtual machines on my desktop with different browsers installed on different windows OS versions. Although these machines will never run 24x7 and never all at once (max 2 at once when testing). Apart from that, I also do lot of photo editing (RAW files, Lightroom and works) and bit of video editing/encoding stuff on my dekstop, mostly personal projects, rarely commercial work). Is it better to opt for 3770 for better virtual machine performance or 3770k with chance to boost overall performance by overclocking?

    At the moment, VT-d will not give you any additional performance on your VM's using desktop virtualization programs like VMware workstation or Virtualbox. Neither supports VT-d right now. Based on progress this year, I expect VT-d support is still be a year away in Virtualbox, which is what I use.

    VT-d doesn't help performance in general; instead, VT-d allows VMs to directly access computer hardware. This is essential for high performance networking on servers or for accessing certain hardware like sound cards where low latency is crucial. For your workload, the only advantage will be slightly higher network speeds using native drivers versus a bridged connection. It may facilitate testing GPU accelerated browsers in the future as well.

    If you plan on overclocking, the K series is worth loosing VT-d.

    Thanks, that helps a lot. I've been reading about and VT-d and your comment confirms where my thinking was going. I guess, 3770K it is then. :) Reply
