The Launch Lineup: Quad Cores For All

As was the case with the launch of Ivy Bridge last year, Intel is initially launching with their high-end quad core parts, and as the year passes on will progressively rollout dual cores, low voltage parts, and other lower-end parts. That means the bigger notebooks and naturally the performance desktops will arrive first, followed by the ultraportables, Ultrabooks and more affordable desktops. One change however is that Intel will be launching their first BGA (non-socketed) Haswell part right away, the Iris Pro equipped i7-4770R.

Starting at the top of the product and performance stack, we have the desktop Core i7 parts. All of these CPUs feature Hyper-Threading Technology, so they’re the same quad-core with four virtual cores that we’ve seen since Bloomfield hit the scene. The fastest chip for most purposes remains the K-series 4770K, with its unlocked multiplier and slightly higher base clock speed. Base core clocks as well as maximum Turbo Boost clocks are basically dictated by the TDP, with the 4770S being less likely to maintain maximum turbo most likely, and the 4770T and 4765T giving up quite a bit more in clock speed in order to hit substantially lower power targets.

It’s worth pointing out that the highest “Test TDP” values are up slightly relative to the last generation Ivy Bridge equivalents—84W instead of 77W. Mobile TDPs are a different matter, and as we’ll discuss elsewhere they’re all 2W higher, but that is further offset by the improved idle power consumption Haswell brings.

Nearly all of these are GT2 graphics configurations (20 EUs), so they should be slightly faster than the last generation HD 4000 in graphics workloads. The one exception is the i7-4770R, which is also the only chip that comes in a BGA package. The reasoning here is simple if perhaps flawed: if you want the fastest iGPU configuration (GT3e with 40 EUs and embedded DRAM), you’re probably not going to have a discrete GPU and will most likely be purchasing an OEM desktop. Interestingly, the 4770R also drops the L3 cache down to 6MB, and it’s not clear whether this is due to it having no real benefit (i.e. the eDRAM functions as an even larger L4 cache), or if it’s to reduce power use slightly, or Intel may have a separate die for this particular configuration. Then again, maybe Intel is just busily creating a bit of extra market segmentation.

Not included in the above table are all the common features to the entire Core i7 line: AVX2 instructions, Quick Sync, AES-NI, PCIe 3.0, and Intel Virtualization Technology. As we’ve seen in the past, the K-series parts (and now the R-series as well) omit support for vPro, TXT, VT-d, and SIPP from the list. The 4770K is an enthusiast part with overclocking support, so that makes some sense, but the 4770R doesn’t really have the same qualification. Presumably it’s intended for the consumer market, as businesses are less likely to need the Iris Pro graphics.

The Core i5 lineup basically rehashes the above story, only now without Hyper-Threading. For many users, Core i5 is the sweet spot of price and performance, delivering nearly all the performance of the i7 models at 2/3 the price. There aren’t any Iris or Iris Pro Core i5 desktop parts, at least not yet, and all of the above CPUs are using the GT2 graphics configuration. As above, the K-series part also lacks vPro/TXT/VT-d support but comes with an unlocked multiplier.

Obviously we’re still missing all of the Core i3 parts, which are likely to be dual-core once more, along with some dual-core i5 parts as well. These are probably going to come in another quarter, or at least a month or two out, as there’s no real need for Intel to launch their lower cost parts right now. Similarly, we don’t have any Celeron or Pentium Haswell derivatives launching yet, and judging by the Ivy Bridge rollout I suspect it may be a couple quarters before Intel pushes out ultra-budget Haswell chips. For now, the Ivy Bridge Celeron/Pentium parts are likely as low as Intel wants to go down the food chain for their “big core” architectures.

For those interested in the mobile side of things, we’ve broken out those parts into a separate Pipeline article.

    Finally, let's see how good Haswell is. Reply

    Disappointing, to say the least. He's even comparing it to 2-3 older generations, just to be able to write some non-embarrassing numbers in the review, considering Haswell is only like 5-10% faster than IVB.

    The only big improvement seems to be in idle power consumption, of about 30%, which seems to "impress" Anand, but it just means that if your laptop had a 12h idle time, now it gets 16h.

    It won't do much in ACTIVE power, which is really what matters. So much for all the "Haswell will totally dominate tablets in the near future" hype from Anand. Yes, this is not the mobile version, if Haswell really were an impressive design for power consumption, you'd see it here, too. It actually consumes 5-10% more than same clock speed IVB chip, which means its extra performance is almost completely negated.

    This means that my predictions that Intel will try to "trick" us into thinking Haswell is ready for tablets will soon come true. Because if Haswell is not that efficient to warrant being used in "normal" tablets, then they'll try to dramatically lower clock speed and performance to even achieve 10W TDP (still too high for a tablet).

    Pretty good points.

    I'll still upgrade from my i5 750, and we won't get anything interesting until Skylake on the desktop (apparently, it wont be BGA), as I'm expecting motherboard OEMs to force us into buying their high end motherboards with any of the high end i7s Broadwell.

    I'm using an i7-950 (over 4 years old) and its funny seeing how still-competitive it is to Intel's newest chips. It seems Sandy Bridge brought the bang and its just been trickle down performance since... Reply

    No kidding, I'm in the same boat and was thinking of upgrading but with my moderate over clock and these results have no problem waiting until the next generation. Reply

    I'm still running my i5-2500k @ 4.3GHz and see nothing here of interest. I don't see myself upgrading any time soon. Reply

    I'm still running an E8400. I see plenty of reason to upgrade. Reply
  • dananski - Monday, June 03, 2013 - link

    Ahh I had one of those until this time last year. The E8400 found a happy home with a friend and I went to Ivy Bridge. Even small improvements like Sandy -> Ivy -> Haswell are useful, so don't feel too bad for having waited so long. Reply

    haha. I'm still running an OC'd E6600 (amongst others) for my desktop, which I hardly touch anymore, and am unsure whether to upgrade. I'm curious to see how Haswell performance vs power consumption vs price, is for NAS systems.

    Aside from natural degradation in one of the components (cpu, memory, psu, or gpu), which brings on an error every once in a while, the E6600 still does 98% of what I want of it and 100% of what I need it to do. So I suppose my needs are to get my electric bill down.

    I need to read more because I was hoping this chip would bring me to buy a Surface Pro.

    You will get benefits upgrading from E6600 no doubt about it. For you its worth it as you are going to get a lot less power consumption, cooler operating chip and less noisy as well, with a significant performance increase especially in multithreaded applications, but for those thinking upgrading from Sandy or Ivy bridge to Haswell its worthless.

    I mean upgrading from 2500k to the new 4770k is useless. At best you are going to see 40% performance improvement which calculates into 5 seconds faster decoding or 5 seconds faster unzipping, but at worst you are going to get 2% performance increase which amounts to milliseconds of faster decoding and stuff.

    You are not going to get less power consumption and it seems you may even get worse power consumption at loads. The new chips don't even overclock as well either, so its a waste of money to upgrade. If you have 3-4 generations older chip its worth upgrading, but else your money is better spent elsewhere.
