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.

    It confirms Temash tablets will be the GPU+CPU performace / power / price ratio to beat. Reply

    At 8-15W. What size market is that again? It's like saying Amtrak has a better cost/distance than a Prius. Yes, but so what? Reply

    its not disappointing at all, its gains, and any gains matter on an annual schedule. As long as it beats Ivy by any percentage, its progress. You know Intel's goals are not IPC related as much as mobile, so dont rant when all the facts are in front of you. Reply

    You must have missed the part where S0ix isn't available on the desktop parts. How about you wait until the MOBILE and ULV processor tests are in before you start ranting. Reply

    The point of Haswell is not to drastically improve performance. Haswell is designed to move x86 into the tablet and mobile market with drastically improved idle and low power performance. Skylake, in roughly 2015, will likely be the next big performance boost. Reply

    "Haswell" isn't going into tablets Reply

    It does - Surface Pro class.(TDP 10W) Reply

    Well I am happy to see the 4th gen release. And yay PCI is now officially gone. Shouldn't there be a memorial ceremony? And maybe a trophy? :)

    Kudos to the first posters looks like they some what actually read the review, even tho I don't know if I agree with your comments.
  • klmccaughey - Monday, June 03, 2013 - link

    Yes, it is great to see PCI finally dead and buried. It's been a bit like having a tow bar on a ferrari this last few years. Hoorah for the death of PCI!!! :) Reply

    Where this will probably shine is in mixed workloads. Not overclocking for gaming or production.
    It will be easier to put Haswell into (G)HTPC builds at mini-ITX and µATX formfactors and keep noise down while still having great burst performance. The 4770K seems to be not worth it for overclockers that have got good Sandy/Ivy chips.

    I think i may upgrade my parents living room PC to something like a mini-ITX build with i3-42xxT, and just transfer the SSD (Force GT 120GB) and RAM (8GB 1600 SO-DIMM). It should be a substantial upgrade from E-350 and almost fit the same power envelope for their use cases.

    I'm looking more forward to more info on Ivy-E. I'm happy with my 3930K with a decent OC, but if Ivy-E can bring the power/performance ratio down without bringing performance down or heat issues, i might upgrade :)
