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.

    These are some very good processors. What is misplaced though is the graphics part. It is ok for mobile processors to have such a part, but for high energy consuming desktop processors, it is irrelevant and more of a burden. In the desktop world you expect a cpu with the highest possible processing power. It is 2013 and quad core is kind of old, come on intel don't be shy bring 8 and 10 core processors, you have the room to accommodate it. If I want graphics I 'll buy a monster graphics chip and will not be bothered by "optimal" power consumption.
    It is sad to see the energy efficiency and the computing efficiency improving only to accommodate a miserable graphics card. If you want us to buy graphics together with the cpu(an apu) make a chip with a tdp 300-400 because this is a mainstream energy budget for the desktop.
    If it is impractical(which is probably the case) build your own discrete graphics.
    Don't vandalize your cpus this way. If you want the mobile go for it, just don't contaminate your desktop products.

    same with me!
    I'm currently running an E8400@4,5GHz since 2008, and now seems a good time to upgrade.
    I hope the haswell chip will overclock just as good. From what I've read that means that I may have to exchange the thermal paste under the IHS for some coolaboratory stuff...
    Not decided on i5 or i7 yet though...

    You shouldn't have expected a reason to upgrade yet. Sheesh...we knew it would not be a real upgrade over an SB or IB CPU. Reply

    I built a new from the case up Z77 rig with a 3570K processor running 24/7 @ 4.4GHz last fall. I seriously considered waiting for Haswell to hit the market before upgrading my machine (circa 2007). I'm glad I didn't wait any longer since, I have been running a damned fast machine for 8 months now. I think I may have felt perhaps a little bit underwhelmed if I had waited for Haswell. Just my 2 cents worth. Reply

    Yep...I built up my current 3570k system around the summer last yearyear Reply

    While you are right that load power consumption is higher, the system is not loaded all the time.
    Not for the common users any way. In that case, idle will serve as a better power performance indicator as opposed to load consumption.

    Pulling up this website and browsing my CPU utilization is under 20% and under 10-5% the majority of the time. Now I'm 5 years back on a Core2Duo. I'd imagine by now, if I was browsing this page on a Haswell, it'd be even lower considering processors are much faster as well. So mobile side I'm guessing that average battery life increased quite a bit. We'll see with the review. Using LOAD power consumption to judge mobile though is just plain ignorant.

    This is why some people need to stick to reading reviews, and wait for full reviews come out, rather than jumping to early conclusions and misinterpreting information.

    So, what about people that want to gaming on laptop? Reply

    Did you realize that these are all desktop chips? Let's not judge using desktop parts. But seriously, what percentage of users game with a mobile quad core & intel graphics? Reply
  • krumme - Saturday, June 01, 2013 - link

    5-10% is on the positive side imho.

    Sometimes it can even be slower :)
    This processor is not intented for desktop. There is nothing wrong in that. But why all this bs covering it. Its a fine processor and a weird and shallow review.
