Intel Core i7-3770K Review: A Small Step Up From Sandy Bridge

Benchmark Results: File Compression

Recently adopting WinZip 16 doesn’t seem to have helped with the software’s inability to utilize multi-core processors effectively. As such, Ivy Bridge’s slight IPC advantage garners it another top finish, just ahead of the Core i7-3960X and -2700K. Fortunately, we have inside information that indicates WinZip’s next incarnation will be more competitive.

More aggressive optimizations for parallelism give Intel’s Core i7-3960X an edge in WinRAR, allowing it to reclaim the top spot, though the quad-core Ivy Bridge chip does manage to tie the £440 Core i7-3930K.

Let’s not mince words, though. Core i7-2700K is just one second behind the new chip, and the £170 Core i5-2550K is just two seconds back. You certainly won’t have much to complain about if saving some money is more important than waiting a couple of extra seconds for a folder full of files to compress.

Long known as the file compression/decompression utility in our suite best optimized for multi-core processors, 7-Zip puts both Sandy Bridge-E based CPUs in the lead, followed closely by Core i7-3770K.

The real loser here is Core i5, which sports four cores, but lacks Hyper-Threading, landing it in last place. AMD’s Bulldozer-based FX-8150 fares better in the face of more aggressive threading, though it can’t quite catch the Core i7-2700K.

    Thanks for the pretty quick review. The HD 4000 may be a tempting factor for many low-end desktop users. High-end users are unlikely to switch to IB. Unless extensive future reviews show a different picture, Sandy Bridge would be the CPU for my high-end new build!

    4% on average is a pretty small performance bump from a dye shrink i was hoping that ivy was gonna be in the region of 10% but i guess a small bump is better than none. still not a big enough jump for me to give up my old i7 920... ah well maybe haswell will deliver.

    Well I think this will be improved in no-time, the guys are doing well in their new architecture and finding new ways to make the big jump. This is like testing, their stuff is good enough to get on the market and they can earn a lot of credits that will help them to keep working hard with new stuff.I really liked their quick sync thing.
    I still don't know the negative points in including gpus in cpus.

    US comp. You would think they could put that somewhere in the article.

    I'm personally very excited by Ivy Bridge. I'm not planning on replacing the first gen i5 in my gaming rig, I can't see the benefit. But I'm looking at replacing the Sempron 1100LE in my server with one of the low power i3 chips when they come out. For a computer that runs 24/7, power consumption and noise are fairly important to me for that machine. The Sempron and the low end i3 have similar TPD ratings, but there's a gulf of difference in performance.

    An unlocked, "K" variant of the i3, or Pentium-G? That might get people excited...

    I'm happy with my FX-6100...Even if I had the money, I wouldn't upgrade it, except for maybe a 8150. This CPU is amazing, and no review on here or anywhere really does it justice. It handles every game i throw, I can convert a 6gb HD video to MP4 in 5 mins WHILE photoshop, and a game is running

    I still do wish that Intel offered a cheaper or more powerful CPU without the built-in GPU. It seems like a big waste of time, work, and die space (and maybe even money) for, esp. now, such a big GPU portion. But maybe from the business/profit-spending point of view, it really is better for Intel as a company to have GPU's built-in irregardless.

    I'm interested in hearing from anyone else's thoughts on this.

    I see and hear about the reasons for not upgrading from Sandy-bridge to Ivy-bridge, but I would be interested in pointers for someone who has not had a desktop for about 5 years but is now looking for a new architecture which will be as long lasting as possible so I can buy a good ($200-$300) motherboard and a cheaper processor with a view to upgrading all components (memory / graphics etc) on the motherboard as time and money permits. I'm thinking either 1150 or 2011 but would appreciate some general guidance
