Faster accouterments shouldn’t be this somber. Yet we can’t advice but channel our countenance in affair over Intel’s fourth-generation Amount i7 CPU, Haswell. Yes, in archetypal Intel fashion, it’s a bout de force of abstruse accomplishment and appearance that’s the backbiting of the chargeless world. It’s also, by the way, absolutely fast.
How fast? *Spoiler alert* Let’s just say that the new Amount i7-4770K calmly unseats the antecedent midrange sweetheart, the Amount i7-3770K, as the best all-around performer, and even gives the high-end hexa-core allotment a harder time.
So, why are we so sad? Maybe it’s the around-the-clock whispers of the PC’s approaching doom—that admitting the authentic joy a able PC can accompany the world, its canicule are numbered.
Or maybe it’s because it’s bright that, while Haswell is fast, it’s a allotment that is acutely advised primarily to account laptops, tablets, and added small-computing needs rather than desktops. Let’s just say, as blessed as we are about area Haswell acreage in performance, we’re still anxious about Intel’s charge to achievement desktop computing, and that doesn’t accomplish us feel good.
The Haswell Lineup
One new Haswell includes the south arch central the package.
Haswell’s Mixed BagA new belvedere is just one of the appearance that adeptness irk enthusiasts. The a lot of credible change for any enthusiast is the addition of a new socket. LGA1155 has agitated us from Sandy Arch through Ivy Bridge, but as Intel doesn’t like you to anytime get too adequate with a motherboard, it’s address that old LGA1155 for a new LGA1150 socket. The two are, of course, incompatible. Why? It’s not just to piss you off, but added acceptable due to the actuality that Intel can’t accommodate the new Haswell appearance in LGA1155. The new atrium should appear as no abruptness to anyone who reads Maximum PC, as we’ve been advertisement on Intel’s plan for Haswell for a while, but actuality it is officially: If you wish the new CPU, you charge a new motherboard. AMD /AM3+ fanboys can feel chargeless to absolve a big Nelson Muntz–style “ha-ha!” in the faces of Intel fanboys.
You're traveling to charge a new 1150-socket Mobo for Haswell
Got a Spare FIVR, Buddy?We’ve continued said that Intel’s CPUs are gravitational atramentous holes sucking aggregate into them. Nehalem ate the anamnesis controller. Lynnfield swallowed PCIe. Sandy Bridge gobbled up graphics. And Haswell has a new absolutely dent voltage regulator, or FIVR, central the package. By amalgam the voltage regulator, Intel simplifies adeptness inputs into the CPU but aswell takes a lot of the ascendancy out of the motherboard makers’ hands. The FIVR doesn’t annihilate all voltage adjustment on the motherboard, as the adeptness to the CPU accept to still appear from somewhere, so you’ll still acquisition boards with able-bodied caps and voltage adjustment circuits.
By amalgam the VR, though, Intel is able to adapt adeptness to a abundant bigger amount than has been accessible on even the best motherboards. Voltage ripple is about nil on the design, and the achievement of the FIVR outstrips annihilation that can be done externally. The FIVR aswell technically lowers the amount of a motherboard, as some of the alien voltage regulators are no best needed.
The FIVR isn’t a chargeless ride, though. It adds added calefaction to the CPU and raises the TDP of the 4770K to 84 watts compared to the 77 watts of its predecessor.
The bigger catechism for desktops users is, why? The harder accuracy is that we doubtable the change was not done to account desktop PCs. It’s to account laptops, all-in-ones, and annihilation abroad that absolutely needs absolute ascendancy over adeptness and voltage in a absolute attenuate package. In added words, it’s a move that’s all about adaptable and baby computing. The acceptable account is that it doesn’t assume to aching enthusiasts absolute much. Yes, you’ll charge able-bodied cooling to run Haswell overclocked, but you consistently bare that.
Overclocking Accord and TakeWhen Intel jumped from Lynnfield to Sandy Arch chips, it larboard abaft the adeptness to pump up the abject alarm to overclock a chip. Overclockers still got apart “K” CPUs, but even non-K locations could overclock by four bins through the multiplier on Z-series boards. With Haswell, that affection is now gone, so non-K locations are absolutely clock-blocked in every way possible.
The acceptable account for enthusiasts is that Intel has added added knobs to K-chip overclocking. Borrowing from the Sandy Bridge-E chips, Haswell K chips will now action added CPU straps for overclocking. Rather than accepting bound to just 100MHz and a few megahertz aloft it, added ratios of 125MHz, 160MHz, and 250MHz should be accessible to advice overclock the CPU after overclocking PCIe and added clock-sensitive components.
Big Fat L4—Just Not for YouOne of the a lot of agitative developments in the Haswell locations account is the new Amount i7-4770R. This one dent appearance a massive 128MB of anchored DRAM, or eDRAM, to alleviate anamnesis bandwidth issues in graphics. Don’t affliction about dent graphics? You should, because the R part’s eDRAM aswell acts as a massive L4 cache, which, according to some developers, offers a appealing big addition in achievement alfresco of graphics. The absolutely bad account is that you can’t get it in annihilation added than a BGA dent today. After audition the objections of the enthusiast tech columnist (see, we advice you sometimes), Intel is searching at the advantage of alms a alveolate R chip.
TSX for Alone Some of UsMuch has been said about Intel’s transactional anamnesis feature, or TSX, in Haswell. TSX about makes it easier for programmers to address multithreaded cipher by acclamation the complexities of accepting to lock portions of an arrangement of data. TSX lets the processor handle abundant of the balance work. Now for the bad news: TSX is allegedly alone accessible on some Haswell chips. Intel wouldn’t say which chips had it and which didn’t, but a leaked blueprint on Tom’s Accouterments indicates that the alone two chips we affliction about—the two apart K parts—don’t accept it.
And the Acceptable News?So, Haswell runs a bit hotter, takes some voltage ascendancy out of your hands, eliminates the non-K overclocks, doesn’t accord enthusiasts admission to the ample L4 accumulation version, doesn’t accept TSX in the K parts, and, well, requires a new motherboard, too. You’re apparently apprehensive just area the hell the acceptable account is for enthusiasts with Haswell.
Despite all our bitching, we will say that Intel has at atomic paid absorption to the one metric that counts most: performance. Intel didn’t just yield an Ivy Arch die, abolish the name, and pencil in Haswell. The aggregation has added new instructions to Haswell, including AVX2 and FMA2, that will eventually account you. The aggregation has aswell added the beheading ports and about fabricated a lot of nips and tucks in the name of performance. What this agency is that, alarm for clock, Haswell offers a credible achievement addition over Ivy Bridge. The abounding angular on Haswell’s achievement follows, but let’s just say it again: It’s fast. The credible abridgement of TSX, fat L4, and multiplier overclocking adeptness accord you a frowny face, but maybe the alone humans who should absolutely accept a frowny face are those who just bought into a full-boat LGA1155 arrangement with a top-of-the-line Amount i7-3770K chip.
Haswell Cartoon Assuredly Acceptable Enough? We’re traveling to bang that football to the moonIntel’s x86 accomplishment has about consistently been the backbiting of the chargeless world. We can say that after anyone except the a lot of agog AMD fanboy objecting, because if it comes to x86 performance, Intel has thoroughly bankrupt everyone’s clocks. From PowerPC to 68000K and from SPARC to MIPs, Intel’s x86 locations accept beatific anybody packing.
When it comes to graphics, though, a lot of accede it’s been the exact opposite. Old salts will bethink Intel’s adverse access into detached cartoon with the i740 in backward 1990. Admitting analyst predictions of an Intel-led graphic-card-ageddon, Intel instead withdrew with its video agenda amid its legs two years later. Admitting a sucktacular non-success, Intel angry lemons into gold-plated lemonade if it anchored i740 into the 810 chipset. Believe it or not, today, Intel’s dent cartoon boss in bazaar assimilation over AMD and Nvidia cartoon chips.
But Intel wants added than to alone excel at sucky graphics, and has been on a abiding advance to accretion some respect. Every year, Intel proclaims its dent cartoon abundant improved, and usually humans absolve it off as Lucy trolling that sap Charlie Brown. With Ivy Bridge, though, Intel’s cartoon absolutely got better, but all-embracing still couldn't attempt with even low-end detached parts. This time, Lucy says, it’s different. But is it? Are Haswell cartoon really, assuredly acceptable abundant to alter detached graphics? We can’t say—yet.
First, to be fair to Intel graphics, our adeptness to adjudicator its achievement is alone based on the HD4600 allotment anchored in the Amount i7-4770K chip—a CPU no one is acceptable to use after a detached GPU. The HD 5000 and HD 5200 are in actuality the “real deal,” but we couldn’t get our mitts on them. HD4600 is absolutely bigger than Ivy Bridge, though. To compare, we acclimated the aforementioned rigs we acclimated for the added benchmarks in this story, but ripped out the detached cards. We saw Haswell alms a advantageous access over Ivy Bridge. In fact, in Portal 2, which we advised unplayable with Ivy Arch at 1080p resolutions, Haswell gave us reasonable (but not fantastic) anatomy ante with angel superior angry down a few notches. Not bad, honestly. Resident Evil 6 at 1360x768 saw Haswell with alert the achievement of Ivy Bridge. Added amateur aswell gave Haswell a acceptable leg up over its predecessor. Abundant to alter detached graphics? Hell no. At least, not with HD4600.
The Bantha in the allowance is absolutely Intel’s HD5200 graphics. With its 128MB of eDRAM, we doubtable that it’ll accord even AMD’s best APUs a complete thrashing and adeptness assuredly be the football Charlie Brown has been cat-and-mouse to bang all these years.
Haswell vs. Ivy Arch GraphicsHaswell Meets the Benchmarks: A Mobile-friendly Architecture Doesn’t Diminish Desktop Performance
Picking which CPUs to analysis was adequately straightforward: We went with the top-end Amount i7-4770K, a Amount i7-3770K, and to accord humans a angle on how LGA2011 chips compare, a Amount i7-3820. Even admitting it’s out of the amount bandage of the three others, we aswell absitively to analysis the hexa-core Amount i7-3930K to appearance the quad-core boys what they’re missing, or not, by above the two added cores.
While differing sockets fabricated it absurd to use identical motherboards for our tests, we at atomic ashore with one bell-ringer in the hopes of accomplishing some uniformity. For LGA1155, we acclimated an Asus P8Z77-V Premium, for LGA2011 an Asus Sabertooth X79, and Asus’s new Z87-Deluxe lath for the LGA1150. Anniversary motherboard was outfitted with 16GB of Corsair DDR3 clocked at 1,600MHz. All three systems were outfitted with identical 240GB Corsair Neutron GTX SSDs, which had the aforementioned firmware and were Trimmed afore testing began. For graphics, analogous GeForce GTX 580 cards were used, with the aforementioned disciplinarian on each. For OS, we acclimated Windows 8.
As ahead mentioned, in performance, Haswell doesn’t disappoint. For example, we ran Cinebench 10 beyond just one amount to barometer the per-core performance. Haswell gave us about a 17 percent bang over Ivy Bridge. Adjoin the earlier Sandy Bridge-E cores in the Amount i7-3820, Haswell was about 30 percent faster.
In the added benchmarks, Haswell’s advantage remained constant, with the new CPU assuming faster than Ivy Arch in just about every category, and the margins addition adjoin the Sandy Bridge-E chip.
For the a lot of part, Haswell offers an 8 to 15 percent achievement addition over Ivy Bridge. In the heavily threaded Premiere Pro CS6 test, Haswell enjoyed a 12 percent advantage. The aforementioned 12 percent advantage aswell popped up in our ProShow Producer test, which acme out at about four threads.
In a seek for added real-world results, we absitively to bandy HDRsoft’s accepted PhotoMatix at the CPU. We acclimated a nine-shot RAW book from a Nikon D800 and ran a accumulation catechumen on it. From what we can tell, that accurate amount is heavily multithreaded and in fact stops aggregate abroad while accepting run. Haswell pulled out a big win, processing the HDR about 22 percent faster than Ivy Bridge.
In the constructed 3DMark gaming tests, both CPUs pulled even in the cartoon test—no surprise. But in the physics test, Haswell afresh had a 10 percent accretion over Ivy Bridge. In absolute bold engines, the aberration amid the two CPUs varied. We ran our tests at low superior and low resolutions to yield the GPU out of the equation. In Dirt 3, we saw an alarming 34 percent aberration amid Haswell and Ivy Bridge, and in Total War: Shogun 2’s CPU test, a 10 percent gain. We could go on, but for the a lot of part, Haswell is all-embracing faster. Allotment of the achievement improvements appear from Intel’s under-the-hood tweaks to the chip, but some of it aswell comes from the Turbo Addition modes. We monitored the chip’s alarm acceleration in some tests and begin that sometimes it would run at 4.1GHz for continued stretches of time, while the Ivy Arch dent afraid aback at 3.8GHz. Combining both the college Turbo Addition speeds and the ability enhancements explains a lot of of its wins adjoin Ivy Bridge.
Haswell already has a leg up over Ivy Bridge, but up adjoin the even earlier Sandy Bridge-E cores, it’s a bit of a slaughter. If you were to peg the advantage Haswell has over Sandy Bridge-E, we’d say it’s about 20 percent all-embracing if its four cores against four cores. The alone advantage Sandy Bridge-E picks up is if you get to six cores. The Amount i7-3930K has an advantage in heavily multithreaded tasks such as 3D apprehension and video encoding. In gaming and apps that absolutely can’t accomplishment all six cores of the Amount i7-3930K, Haswell comes out on top.
What Should You Buy?First, Haswell doesn’t invalidate Ivy Arch systems. Machines congenital on Ivy Arch are still absolutely fast and action affluence of performance, but there’s artlessly no acumen to body on an older-generation CPU with a asleep atrium (good luck accepting addition LGA1155 out of Intel) with an inferior chipset. Sorry, but that’s the truth, and we apperceive some of you just congenital Ivy Arch boxes, too, admitting our admonishing you to delay a ages or so.
When it comes to Haswell Amount i7-4770K vs. Amount i7-3820, it’s a bit added tricky. Haswell apace leaves quad-core Sandy Bridge-E in the dust. The alone acumen to even body a Amount i7-3820 box at this point is with an eye against approaching upgrades. Intel is accepted to advance out Ivy Bridge-E or Ivy Town CPUs after this year.
That’s appealing abundant our advice for Amount i7-3930K, too. The dent is about alert as big-ticket as Amount i7-4770K but if you plan for a active blame pixels in a 3D renderer, or video encoder, it’s account it. If you can cut a four-hour video encode down to three hours with Amount i7-3930K, you can plan on added projects that pay, rather than wait. The alone admonition is that Haswell’s college alarm and bigger amount can in actuality be as fast, even on multithreaded workloads. Peep our PhotoMatix analysis that saw the Amount i7-4770K in actuality exhausted the six-core Amount i7-3930K.
Despite all our negativity, we accept to say, Haswell can still accomplish us smile. We can’t advice but wonder, though, as absorbing as Haswell is in performance, what it could accept been like if Intel had focused on authoritative Haswell a absolutely desktop-enthusiast part. We abhorrence those canicule are abaft us, though.
