Intel Announces Devil's Canyon Core I7-4790K: 4GHz Base Clock, 4.4GHz Turbo 157

Posted by timothy from the let-the-bleeding-edge-do-the-bleeding dept.
MojoKid (1002251) writes "Last year, Intel launched two new processor families based on the Haswell and Ivy Bridge-E based Core i7 architecture. Both chips were just incremental updates over their predecessors. Haswell may have delivered impressive gains in mobile, but it failed to impress on the desktop where it was only slightly faster than the chip it replaced. Enthusiasts weren't terribly excited about either core but Intel is hoping its new Devil's Canyon CPU, which launches today, will change that. The new chip is the Core i7-4790K and it packs several new features that should appeal to the enthusiast and overclocking markets. First, Intel has changed the thermal interface material from the paste it used in the last generation over to a new Next Generation Polymer Thermal Interface Material, or as Intel calls it, "NGPTIM." Moving Haswell's voltage regulator on-die proved to be a significant problem for overclockers since it caused dramatic heat buildup that was only exacerbated by higher clock speeds. Overclockers reported that removing Haswell's lid could boost clock speeds by several hundred MHz. The other tweak to the Haswell core is a great many additional capacitors, which have been integrated to smooth power delivery at higher currents. This new chip gives Haswell a nice lift. If the overclocking headroom delivers on top of that, enthusiasts might be able to hit 4.7-4.8GHz on standard cooling."

(The new server boards with Atom C2750 are nice for multi-threaded workload in a similar performance range, with very little power, though. That depends on what you're running, of course. More expensive though, but you get ECC and proper server interfaces at least.)

      Because most people don't care about these things anymore. Take this from TFS:

      Haswell may have delivered impressive gains in mobile, but it failed to impress on the desktop where it was only slightly faster than the chip it replaced.

      In reality, Haswell had double the FLOPs thanks to the new FMA instructions, near double the integer throughput thanks to AVX2, and a significant boost to multithreaded code thanks to TSX.

      In practice, people saw maybe a 10% speedup in what they actually do. A flops/$ metric would significantly inflate the actual value people would see from these CPUs.

      The thing is, these measurements are either synthetic (who has code consisting of nothing but FMA?), hard and uncommon to use (Integer SIMD is rare and AVX2 has a confusing idea of "lanes" that splits some 256-bit ops into two 128-bit ones), or not on all CPUs (TSX is disabled on their unlocked K line for some reason).

The same system with the E5-2630 v2 has 64GB of RAM, a 500GB Samsung 840 EVO and five 2TB WD Red drives in RAID-5 connected to an Adaptec 6805 with battery backup. Reads and writes to the SSD and the array are at similar speeds (between 400MB/sec and 600MB/sec), and more than one app hitting the disk at the same time doesn't make things slow to a crawl.

The i5-4690K is similar to the i7-4690K, dropping hyperthreading, a bit of cache and some stock clock, but for $100 cheaper ($242 instead of $339, if reports are accurate).

    The really interesting one is the Pentium G3258. Two cores, no hyperthreading, but with an unlocked multiplier, for $72. If you care more about single-threaded performance than multi-threaded, this might be a very cool thing. Buy one, and a good aftermarket cooler, and overclock it into the 4GHz range. If your load is mainly single-threaded, like far too many games are, that can give you the same performance but be much, much cheaper.

    My 2 year old Ivy Bridge Core i7 is fast enough, and will be fast enough for the foreseeable future with no overclocking. Neither Intel nor AMD will get any money from me for at least 3 more years ;)
    Last time an overclock was meaningful for me was when I had a Pentium 1 at 233 Mhz. The bus was 66 Mhz, and that was the ram speed as well. Upping it to 250 Mhz on a 100 Mhz bus (remember back when multipliers went in 0.5 steps?) speed greatly improved the overall responsiveness of the system.

      The sad thing is that my positively ancient Core2Duo 2.4Ghz is still plenty fast for most tasks these days. This isn't the old days where upgrading the CPU every couple of years gave noticeable improvements to the OS and generic applications like word processors and web browsers. Worse, application developers have been focusing on improving speed (especially on browsers) instead of just jamming in more features. Its getting harder and harder to find motivation to upgrade. We really need some CPU depend

        Yeah, my needs are already above the norm. I could do with your core 2 duo for about 90% of my stuff. Heck, I could do with my 2009 macbook white for about 90% of my stuff.

  • One of the two new "features" is basically TIM that doesn't suck so much?

    A) The first thing than an OC does is wipe whatever the fsck is on there off.
    B) Quality stuff is literally 4$ a tube, and per application is measured in pocket change. Is that significant to the cost of a high end CPU?
    C) Many new components like aftermarket HS and water blocks now come with quality TIM, and not just silicone sludge.

      They're talking about the *other* layer of TIM, between the metal capsule that you wipe off and the actual CPU core. Can't access it without a razor blade.

      You may be confused. They aren't referring to the white silicone paste or the sticky pad that is normally use to attach the heat spreader (top of the CPU you normally see) to the OEM heatsink/fan.

      They are talking about the material used to attach the heat spreader to the actual CPU core. Unless you are prying the metal cap off the top of the CPU you aren't replacing this existing TIM with your $4 arctic silver compound.

      • Ah. Obviously didn't read the article.

        Though I remember people lapping CPU's back in the day, though again that was more to level and ensure a good mating with the HS. Thought I have seen some that got the metal pretty thin as well almost exposing the core.

        However the whole conversation is a bit moot. By Intel "targeting" the OC you pretty much eliminate the purpose for doing so in the first place. The whole idea was you take a cheap chip, and OC it to something much better. Now the chips you can OC are mor

  • I think the most significant thing is that they managed to break the 4GHz barrier. Is this a one off, or did they finally come up with the technology required to make >4GHz chips a standard thing from now on?

  • Sounds like a really cool product. It's a pity intel has over-segmented their product line and I can't get this chip with ECC. That would be cool. In fact, ECC should some day become a standard feature. But that's just wishful thinking.

  • For a person owning a single workstation power consumptions means little.

    Even if you are an intel fanboi, look at the single core performance, in a comparable test.

    I don't thing the newer chips will be much faster at multi-core raytracing either.
