Haswell: a laptop processor you can keep enthusiasts happy

faster hardware should not be so dark. However, we can not furrow our brows in concern for the fourth-generation Intel Core i7,

Haswell

. Yes, the typical Intel, is a feat of technical wizardry and features that are the envy of the free world. It is also, incidentally, quite fast.

How long? * Spoiler Alert * Tell the new Core i7-4770K affection midrange easily thrown above, the Core i7-3770K as the best all-around performer and even gives the high end once hexa-core hard .

So why are we so sad? This is perhaps the constant impending doom that PC murmur, despite the pure joy of a powerful PC can bring to the world, your days are numbered.

Or it may be because it is clear that if Haswell is fast, is something that is obviously intended primarily for laptops, tablets and other small computing needs instead of desktop computers. Say, as happy as we are at the point where the earth Haswell in performance, we are always concerned about the commitment of Intel Desktop performance, and do not make us feel good.

The Lineup Haswell

A new bridge includes Haswell south inside the package.

Mixed Bag of

Haswell

A new platform is a feature that can irritate fans. The most significant change for any lover launches a new socket. LGA1155 led us through Sandy Bridge Ivy Bridge, but Intel does not like you ever get too comfortable with a motherboard, is to lose the old to a new socket LGA1155 LGA1150. Both are, of course, incompatible. Why? Not just to bother you, but it is probably due to the fact that Intel can not integrate new LGA1155 Haswell features. The new decision should not be a surprise to anyone who has read Maximum PC, as we reported in terms of Intel Haswell for some time, but here it is officially: If you want the new CPU, you need a new motherboard. AMD / AM3 + fanboys can feel free to start a Nelson Muntz-style "ha-ha!" On Intel fanboys faces.

You will need a new Mobo-1150 socket for Haswell

FIVR Got a spare, Buddy?

---

We have said for some time that Intel processors are gravitational black holes suck everything in them. Ate Nehalem memory controller. Lynnfield PCIe swallowed. Sandy Bridge graphics swallowed. Haswell and has a new fully integrated voltage regulator, or FIVR, within the package. By integrating the voltage regulator simplifies Intel CPU power inputs, but it also has a lot of control in the hands of motherboard manufacturers. The FIVR not remove all voltage regulation on the motherboard such as the CPU power is to come from somewhere, so I still find tables with high control circuits beefy power.

integrating VR, however, Intel is able to regulate power to a much finer than even the best mothers it was possible degree. Voltage ripple is negligible in the design and performance of FIVR surpasses anything that can be done externally. FIVR technically also reduces the cost of a base plate, and some external voltage regulators are no longer needed.

The FIVR not a free ride, however. More heat is added to the CPU and raise the TDP of 84 Watt 4770K 77 watts against its predecessor.

The most important issue for desktop users, why? The hard truth is that we believe that the change was not made for the benefit of the desktop. Is the advantage of laptops, all-in-one, and all you really need precise control of the energy and power in a very thin package. In other words, it is a movement that is all about mobile computing and small. The good news is that it seems to hurt many fans. Yes, you must run Haswell cooling beefy overclocked, but you still need it.

Overclocking

Give and Take

---

When Intel went from Lynnfield to Sandy Bridge chips, beyond the ability to pump the base clock to overclock a chip. Overclockers processors have yet released "K", but even the parties could not overclock K for four containers through the multiplier in the Z-series boards. With Haswell, this feature is now gone, so that the parties are really stuck clock K in all possible ways.

The good news for fans is that Intel has added more buttons for overclocking K chip. Loans Sandy Bridge-E chips, chips K Haswell CPU will now offer additional straps for overclocking. Instead of being limited to only a few MHz and 100 MHz above, additional reasons to 125 MHz, 160 MHz and 250 MHz should be available to help force the CPU without overclocking PCIe and other sensitive components of the clock.

Big Fat L4-Not Just for You

one of the most interesting parts list Haswell is the new Core i7-4770R. This chip is a massive 128MB integrated DRAM, or eDRAM to improve the bandwidth problems of graphics memory. Do not worry about the integrated graphics? You should, because eDRAM Part I also acts as a huge L4 cache, which, according to some developers, it offers a great performance boost outsized. The worst news is that you can not get elsewhere today nothing BGA chips. After hearing the objections of technology enthusiasts release (see, we sometimes help), Intel is considering the possibility of proposing a connectable smart R.

TSX just for some of us

Much has been said about the role of transactional memory Intel or TSX in Haswell. TSX essentially easier for programmers to write multithreaded code address the complexity of having to block parts of a data matrix. TSX allows the processor to handle much of the dirty work. Now the bad news: TSX is apparently available only in some Haswell chips. Intel does not mean that the chips were and were not, but a letter leak That indicates that only two tabs that are concerned about the release of the two parts K-not.

and the good news?

So Haswell running a little hot, take control of the tension in your hands, do not remove K overclocking gives fans access to the large version of L4 cache, no TSX in K, well you need a new motherboard, too. You're probably wondering just where the hell the good news for fans with Haswell.

for all our complaining, saying that Intel has at least paid attention to the metric that matters most: performance. Intel has not only taken a Ivy Bridge mouth, delete the name and pencil in Haswell. The company has added new Haswell instructions, including AVX2 and FMA2, which over time will benefit you. The company has also increased the application ports and generally made a lot of contact lines and creases in the name of performance. What this means is that the clock on the clock, Haswell offers a significant performance gain on Ivy Bridge. The full skinny on the performance of Haswell, but we repeat: It's fast. The apparent lack of TSX L4 fat and multiplier overclocking you could give a frowny face, but perhaps the only people who should really have a frowny face are those who just bought a system with a cargo LGA1155 limit - basic lines i7-3770K chips.

Graphics Haswell Finally good enough? Kick soccer Either the moon

Intel x86 skill almost always the envy of the free world. We can say that anyone except the subject of the most ardent AMD fanboy because when it comes to the x86 performance, Intel has cleaned watches worldwide. In PowerPC and SPARC 68000K PMI, Intel x86 parts were sent to all packages.

When it comes to graphics, however, most agree that it was the opposite. Sales entry disastrous recall old Intel i740 with discrete graphics in the 1990s. Despite the predictions of analysts conducted a ageddon Intel graphics card, Intel after retirement with a video card between his legs two years later. Despite a lack of success sucktacular, Intel gave plated lemons into lemonade i740 or when integrated into the 810 chipset. Believe it or not, today, Intel integrated graphics dominate the market penetration of AMD and Nvidia graphics chips.

But Intel wants more than just a sucky excel charts, and has been a regular in March to earn some respect. Each year, Intel announced its integrated graphics has improved a lot, and usually people like Lucy shrugged drag this sap Charlie Brown. With Ivy Bridge, but Intel graphics actually got better, but overall still can not compete with even discrete portions of low end. This time, Lucy said, is different. But is it? Haswell graphics are really good enough to finally replace a separate graphics card? We can not say, however.

first, to be fair to Intel graphics, the ability to judge their performance based solely on the built-in chip i7-4770K Core HD4600 party is not likely to be used without a GPU. The HD 5000 and HD 5200 are in fact the "real", but could not get our mitts on them. HD4600 is actually better than Ivy Bridge, though. For comparison, we used the same equipment that we use for other markers in this story, but torn discrete cards. Haswell offered good growth in Ivy Bridge. In fact, Portal 2, it was considered impossible to play with Ivy Bridge with a resolution of 1080p, Haswell gave us reasonable (but not much) frame rates with the image facing down a few notches quality. Not bad, really. 1360x768 Resident Evil 6 Haswell lives with twice the performance of Ivy Bridge. Other games Haswell also got a good advantage over its predecessor. Enough to replace a separate graphics card? Of course not. At least not with the HD4600.

The Bantha in a room is Intel HD5200 graphics. With 128 MB of eDRAM, we suspect that will better the AMD APU could finally be beaten and Charlie Brown football has been waiting to put all these years.

Haswell vs. Ivy Bridge Graphics

Click the next page to see how Haswell compared to Ivy Bridge and Sandy Bridge-E.

Haswell

meets the criteria:

A mobile-friendly design does not reduce the performance of the desktop

choose which CPU test was quite simple: we went with the high-end Core i7-4770K, Core i7-3770K processor, and give people a perspective on how they compare LGA2011 chips , a Core i7 - 3820. Although it is out of the price range of the other three, also decided to try the hexa-core Core i7-3930K to show quad-core kids what they are missing, or not to abandon the two hearts Additional.

Although different plugs make use of identical plates for our tests, at least content with a single supplier with the hope of achieving some consistency. For LGA1155, we used a premium Asus P8Z77-V for Asus Sabertooth X79 LGA2011 motherboard and the new Z87-Deluxe Asus LGA1150. Each plate was equipped with 16 GB Corsair DDR3 clocked at 1600 MHz The three systems were equipped with identical 240GB SSD Corsair Neutron GTX, which had the same firmware and cut before the start of testing. For graphics, we used corresponding GeForce GTX 580 cards, with the same driver in each. For OS, we use Windows 8.

Results

As mentioned above, the performance did not defraud Haswell. For example, we find Cinebench 10 by a single core to measure performance by heart. Haswell has given us a 17 percent bump Ivy Bridge. Against the former core Sandy Bridge-E Core i7-3820, Haswell was about 30 percent faster.

In other benchmarks, the advantage of Haswell has remained constant, with the new CPU to run faster than Ivy Bridge in almost all categories, and the widening of spreads against Sandy Bridge chip -E.

For most, offers a boost Haswell percent yield of 8-15 along Ivy Bridge. In heavily threaded test Premiere Pro CS6, Haswell enjoyed a 12 per cent. The same benefit of 12 per cent has also appeared in our ProShow Producer test, which reaches a maximum of about four threads.

In the search results in real life, it was decided to launch the popular Photomatix HDRsoft CPU. We used a new RAW file shot with a Nikon D800 and ran a batch conversion on it. So we can say that the particular charge is multithreaded and literally everything stops during the race. Haswell took a great victory, HDR processing 22 percent faster than Ivy Bridge.

In tests of synthetic 3DMark games, both CPUs equal to the test table is not a surprise. But the physical evidence, Haswell longer had a gain of 10 percent on Ivy Bridge. In the actual game engine, the gap between the two varied CPU. We did our tests with low quality and low resolution to take the GPU out of the equation. In Dirt 3, we saw an incredible difference of 34 percent between Ivy Bridge and Haswell, and Total War: Shogun 2 CPU Test, an increase of 10 percent. We could go on, but for the most part, Haswell is all-the-board fast. Part of the performance improvements are under the hood settings with Intel chip, but part is also due to Turbo Boost modes. We monitor the clock speed chip in some tests and found that sometimes ran to 4.1GHz for long periods of time, while Ivy Bridge chip fell behind in 3.8GHz. The combination of both Turbo Boost speeds up to and improvements in efficiency explains most of their victories against Ivy Bridge.

Haswell

already has an advantage over Ivy Bridge, but against the more Sandy Bridge-E core is a bit of a massacre. If you were to link the benefit Haswell has more Sandy Bridge-E, it seems that it is about 20 percent overall, when all four cores against four cores. The only advantage Sandy Bridge-E collection is when you get to six hearts. The Core i7-3930K has an advantage in highly multithreaded like 3D and video encoding tasks. In games and applications that can not really use the six-core Core i7-3930K, Haswell comes to mind.

What should you buy?

first Haswell calls into question not Ivy Bridge systems. Built on Ivy Bridge are always very fast machines and offer great performance, but there is simply no reason to build a generation of CPU over a dead socket (good luck getting another Intel LGA1155) with lower chipset. Sorry, but it's the truth, and some of you just built boxes Ivy Bridge, too, despite our warning to wait a month or two.

When it comes Haswell Core i7-4770K vs. Core i7-3820, is a bit more complex. Haswell leaves hard quad-core Sandy Bridge-E in the dust. The only reason I even build a i7-3820 base box is now with an eye to future updates. Should lead Intel Ivy Bridge-E or Ivy processors later this year city.

This is more or less our guide for Core i7-3930K, too. The chip is almost two times more expensive than the Core i7-4770K, but if you work for a living pushing pixels in 3D processor, or video encoder, it is worth it. If you can cut a video encode four hours to three hours with Core i7-3930K, you can work on other projects that pay, instead of waiting. The only caveat is that most core clock Haswell and can actually be improved so fast, even in multi-threaded work loads. Peep our Photomatix test which saw the Core i7-4770K actually beat six-core Core i7-3930K.

Despite all our negativity, we must say, Haswell can still make us smile. We can not help but wonder, however, as impressive as Haswell is running, what could have been if Intel has focused on taking part purely Haswell enthusiastic office. We fear that those days are long gone, however.

Haswell vs. Ivy Bridge pictures

The transition from Sandy Bridge to Ivy Bridge graphics die space was eating a lot more space. To the casual examination Haswell seems almost the same proportion as Ivy Bridge, but a further 200,000 transistors tucked inside. The voltage regulator fully integrated on the motherboard is not actually in the die, but within the package. Intel chip with 128 MB of embedded DRAM memory also display additional silicone band inside the box, but outside the actual matrix.

series 8 Deletes previous errors

finally gives Z87 SATA 6Gb / s through all ports

The new 8 series chipsets ultimately lead to 6 Gb / s SATA across all ports

Intel

We bitched not give us does not give us this or that, but the company has at least finally put our biggest problem since, well, forever. First introduced Intel P67 6Gb / s drives that have the look terrible third SATA native report. The only problem? SATA 6Gb / s are supported on both ports. Already in 2011, it was not a problem as hell had more than two SSD could even push a SATA 6 Gb / s? Today, the price of the SSD really affordable and can saturate the SATA 6Gb / s, which is a problem. Oh, and AMD had 6Gb / s native six SATA ports since 2010 (cue Nelson Muntz again).

The new Z87 chipset fixes this. The six 6Gb / s SATA. Intel also has USB support increased from four to six USB 3.0 ports and 10 USB 2.0 ports for 14 USB 2.0 ports. The Z87 chipset now supports inability to port for security reasons.

There was news earlier this year that the USB 3.0 support on the Z87 chipset was sloppy. USB 3.0 devices apparent error would sleep modes. We asked the panel manufacturers and suppliers who believe that the problem is solved, especially now, and only existed in earlier revisions of silicon, which should not reach the hands of consumers.

addition to support PCI removing the Z87 chipset is not very different from its predecessor.
