Intel Officially Lifts the Veil On Ivy Bridge 200

Posted by samzenpus from the check-it-out dept.
New submitter zackmerles writes "Tom's Hardware takes the newly-released, top-of-the-line Ivy Bridge Core i7-3770K for a spin. All Core i7 Ivy Bridge CPUs come with Intel HD Graphics 4000, which despite the DirectX 11 support, only provides a modest boost to the Sandy Bridge Intel HD Graphics 3000. However, the new architecture tops the charts for low power consumption, which should make the Ivy Bridge mobile offerings more desirable. In CPU performance, the new Ivy Bridge Core i7 is only marginally better than last generation's Core i7-2700K. Essentially, Ivy Bridge is not the fantastic follow-up to Sandy Bridge that many enthusiasts had hoped for, but an incremental improvement. In the end, those desktop users who decided to skip Sandy Bridge to hold out for Ivy Bridge, probably shouldn't have. On the other hand, since Intel priced the new Core i7-3770K and Core i5-3570K the same as their Sandy Bridge counterparts, there is no reason to purchase the previous generation chips."

    So, Intel, a company with no real competition right now in the market, has produced a product that offers only a very slight performance boost, and relied on tons of marketing to drum up anticipation for this mediocre offering. And then priced it the same as existing offerings as an apology to those who waited. Actually, that sounds about par for the course these days. The only real news in cpus and motherboards has been that they've gone multicore and continue to increase bandwidth. And now that they can't squeeze any more performance out of the designs, they're working on decreasing energy consumption.

      For people familiar with Intel's Tick-Tock cadence - this should not come as much surprise. Some people may have gotten caught up in marketing and expected more, but this is a "Tick" which brings a process shrink, power savings, and a modest performance increase. It is just about delivering that, though perhaps on the softer side of things.

      Sandy Bridge was a Tock - a BIG performance improvement. Haswell should be a Tock - a BIG performance improvement.

      On the tick, they set more modest performance goals, and focus on getting the process shrink right and tuning things up. On the tock, they should knock our socks off. So maybe Ivy Bridge is disappointing, but perhaps familiarity with their product development strategy helps to manage expectations

        • Terrible analogy given that there's no analog in the software for the alteration between manufacturing process and microarchitecture design steps that Tick / Tock represents.

      • For people familiar with Intel's Tick-Tock cadence - this should not come as much surprise....

        It comes as a great surprise. Normally, the process shrink delivers either or both a clock boost or power efficiency improvement. Normally, also a speedup due to additional superscalar hardware, but Intel explained that one away as "improved graphics". Well, where did the clock boost go then? Power efficiency? OK, all missing in action. So, the big unwritten subtext here is: Intel's 22nm node has got problems. Big problems. Trigate not working out so well?

        • Higher clockspeeds use more power. Intel hasnt gone much above 3.3gHz for years, with 3.7 (i believe) being the top clock rate that they have ever done. You expect them to change that now when the focus is on higher efficiency, more cores, and lower power usage?

          It doesnt represent a problem at all, and for the record all of the benchmarks ive seen on hothardware (linky [hothardware.com]) show it as being faster than sandy bridge, so theres that speedup youre complaining about.

          They never said that there would be a clock boo

          • You twisted my words up entirely. Let me put it more simply: I am underwhelmed by the "tock" this time. As is every commentator with a clue. This process node appears to be a fail for Intel.

            • And, oh yes, I am underwhelmed by the "tick". On the face of it, Intel would have accomplished more with another go around at 28nm.

              Now for the Intel fanboys in the thread, let's shed some authoritative light [pcper.com] on the subject.

            • vWell, where did the clock boost go then?

              Your words, not mine. You wanted a clockboost (which they really havent done for about 6 years now, and did not promise), and a speedup (which they delivered). You claimed that power efficiency is, to quote your post, "missing in action" (even though it isnt).

              You seem to have assumed they reneged on all their promises despite the reality of the situation, for no other apparent reason than that you wanted something to rail about. Possibly check the sources before buying into the slashdot spin bs.

          Far too early to tell. The fact that they introduced a brand new, immensely complex process into manufacturing and it is working so well actually says a lot of good about how the trigate process is fairing. It will, of course, need some tuning and massaging. But it is already performing as well as/slightly better than the previous generation on its first release, at lower power (at least per Anand).

          IVB is also farking small, which as the process matures, should mean more parts and lower prices.

            Leakage was handled in several ways. Materials technology in semiconductor manufacturing (in particular CPU manufacturing) advanced a lot in the last decade and a half. It used to be chips were all made from polysilicon. Eventually as the transistors got smaller closer to the nanoscale there was work done on new materials (so called low-k and high-k materials). You probably heard about names such as Black Diamond low-k or Hafnium high-k (aka metal gates) along the way. These reduced the leakage issue. Instead of using aluminum for the wires today we use copper to reduce power consumption because copper is a better conductor. Then there is germanium doping to produce so called 'strained silicon' so that the silicon atoms are further apart to improve electron mobility. Taking these material changes and a couple of design changes today's processors are clocking higher than they were 10 years ago even if not at the rate Intel used to predict back then. You probably noticed by now we are either hitting or close to hitting 4 GHz on CPUs while not so long ago they used to be 2 GHz or less with regular air cooling.

            Today people are either doing chip stacking (e.g. on cellphones it is common to stack the DRAM and Flash on top of the CPU module) to make the system more compact. Then there are people working on so called vertical transistors and trigate transistors instead of using regular planar transistors. Ivy Bridge for example is the first processor featuring trigate transistors which is one reason for its low power consumption and reduced leakage over Sandy Bridge. It has been more trouble than usual but it seems everything is ok for the next two process shrinks to work in technological terms. Ultimately we will see the whole system on a chip and CPU/GPU integration is simply the first step with DRAM probably following soon afterwards.

        • It offers a significant power reduction (~22%), plus a slight boost in IPC, same clock rates, and a notable boost in IGP performance (~30%). For instance, i7 3770K (77W TDP, and HD 4000) vs i7 2700K (95W TDP and HD 3000) [anandtech.com]. Both are quad core, 8 thread, 3.5GHz with max turbo of 3.9GHz, and 8MB L3 cache. On the mobile CPU side, a new i7 3612QM, 35W quad core, 8 thread, 6MB L3 cache, and HD 4000 graphics, compared to at least 45W TDP on all prior quad core mobile i7 CPUs (with slower IGP).

      • Okay, so I have been planning a long term computer strategy since 2006 when I got a decent first gen Quad Core.

        So hopefully if I can hold out that long, I should wait for the Tock - Haswell architecture, at the same time waiting for the Post-Win8-Metro consensus, which might just be either a Tock for Microsoft or maybe even a paradigm explosion into Apple and/or Linux if by some Mayan Miracle Microsoft implodes as a company. Or, if there is no "Windows 9", then I'll have to think about what to do then.

      • It avoids a problem many companies have of fighting with a new design and a new process, and having a product that gets delayed, has issues, etc. They either use a new design, on a stable process, or an untested process, with a proven design.

        Sometimes a new process can give a moderate sized performance bump due to higher clock speeds, but that doesn't always happen.

        It does reduce power consumption though and that is always nice.

        Haswell should be a Tock - a BIG performance improvement.

        Don't expect a raw BIG performance improvement. Not like p4 vs core2. But Haswell DOES implement a breaktrough - Transactional Synchronization Extensions. It translates to "transactional memory for threads". An addition of couple of new instructions (may even be available on current CPUs, as they are already documented in the development manuals) to control thread context. Check http://software.intel.com/file/41604 [intel.com] for details.

    • Yes and no. Power consumption is important to some people. The graphics boost will help the majority of consumers that rely on integrated video. Gamers won't care about either but are interested in the performance increase which is slightly better. At the same price as the previous generation, a potential customer has few reasons to buy Sandy Bridge unless they are more focused on cost.

      • Power consumption is important to some people.. Gamers won't care about either.../quote.

        Wrong. Power consumption determines cooling requirements, which determines fan noise. Power consumption also determines whether your long suffering power supply needs yet another upgrade. We are already in circuit breaking blowing zone on a lot of gaming rigs.

        • I would think a gaming rig being able to blow a breaker would be a source of pride to some gamers. MOAR POWER! Ivy Bridge shaves about 18W TDP for some of the new chips compared to Sandy Bridge equivalents.

      Same price
      Compatible with old sockets/motherboards

      And who said every generation of processors had to be a significant improvement? Toyota puts out essentially the same car every year for a decade, with only minor, incremental improvements. There's no reason why you can't do the same for processors. The only downside is for people who like to brag about having the very-latest processor.

      Personally, I'm going to be grabbing an Ivy Bridge laptop, if only because my old, reliable Core 2 laptop finally died. And I'll probably skip over Haswell, maybe Broadwell too, before upgrading again.

      Long story short, if you've got a Sandy Bridge, you don't need to upgrade yet. If you've got a Nehalem and some spare cash, an upgrade may (or may not) be useful. If you're on something before that, IB is the chip to upgrade to.

      PS: I'm not really a fanboy for either company (I've used both extensively - the Phenom's were great, and even my old Athlon 900 still sees service now and again), but AMD really doesn't have any attractive higher-end options.

      Except the summary seems wrong by its own sources:

      TechSpot

      Since late last year Ivy Bridge seems to be the architecture everyone is waiting for. Although Intel is only anticipating a 10–15% processing performance bump when compared to Sandy Bridge,

      Which is what they have been saying for about a year now, and what everyone expected. And for the record, 15% speed boost at the same clock with lower power usage is not insignificant, at all.

      AnandTech:

      Ivy Bridge is a tick+, as we've already established. ... The end result is a reasonable increase in CPU performance (for a tick), a big step in GPU performance, and a decrease in power consumption.

      SemiAccurate:

      For raw numbers, the top HD 4000 only has 16 shaders, but the underlying architecture is completely new. .....Intel is claiming about 2x the graphics performance from 33% more units. We don't think these claims are out of line for the general case.

      Way to go, summary, you successfully implied that the chip was a flop when your sources indicate it hit its target, has substantially better GPU performance, and has a launch price in line with its current lineup. Slashdot truly is master of the art of spin.
