Ryan reviewed the Core i7 4770K earlier in the month and found it an impressive product. He was not able to properly test the CPU paired with a discrete GPU because of time restraints; we value results measured from direct monitor output, which takes longer than FRAPS and other software results. Still, Ryan believes that the boost in raw CPU performance justifies its existence in desktops without a funky "-E" tagged along for good luck.
For a second opinion, you could check NitroWare to see what a cynical Aussie thinks of Intel's latest offering. Of note, they compare software-measured frame rates between the on-chip GPU and those measured from a GTX 460 on Sandy Bridge, Ivy Bridge, and Haswell. He is nothing if not thorough, collecting his findings over 20 pages.
Ultimately he finds that if you are running Ivy Bridge, you will not benefit too much from the upgrade; Sandy Bridge users and earlier, on the other hand, might want to consider this platform... unless they are wanting to jump into the enthusiast-slot offerings coming up late this year and Haswell-E late the following year.
Also be sure to check back when we have our frametime measurements complete!

Intel Prevents Overclocking of non-K Haswell Processors, and Strips Virtualization and TSX Features From K Parts

First revealed at IDF Beijing, Intel's latest generation 4th Generation Core "Haswell" processors enjoy a refined architecture, improved processor graphics, an integrated voltage regulator (FIVR), and for the enthusiast crowd, new methods for overclocking.
In truth, the methods for overclocking Haswell are very similar to those used to overclock Intel's Sandy Bridge and Ivy Bridge processors. However, Intel has further unlocked the new Haswell CPUs. Enthusiasts can set an overclocked Turbo clockspeed, use additional base clock (BCLK) values (100 MHz, 125 MHz, and 167 MHz), and overclock the unlocked processor graphics core clockspeed and memory clockspeed (memory in 200 MHz or 266 MHz steps). The additional BCLK values allow for easy overclocks without putting the other subsystems (such as the PCI-E bus, GPU, and memory) out of spec, which is important for the PCI-E bus which needs to be close to 100 MHz for a stable system.
The following PC Perspective articles have further information on overclocking unlocked "K" edition Haswell processors:
- Integrated Voltage Regulator and Overclocking Haswell - Ryan pushes a Core i7-4770K to 4.6GHz
- Intel Talks Haswell Overclocking at IDF Beijing - Intel outlines overclocking features of Haswell at IDF
Although Intel's overclocking reveal at IDF was fairly detailed, the company did not get into specifics on how overclocking would work on non-K chips.
On that note, the crew over at the Tech Report uncovered some rather disheartening facts such that the non-K edition Haswell processors will, essentially, be locked at stock speeds and not overclockable (they are slightly more locked down than previous generations).
While the K edition Haswell processors, such as the Core i7-4770K, will enjoy unlocked multipliers, unlocked GPU and memory clockspeeds, and additional BCLK options, the standard non-K chips (ie Core i7-4770, Core i5-4670, et al) will have locked multipliers, no Turbo Boost clockspeed overclocking, and will not be allowed to use the additional 125 MHz and 167 MHz BLCK options, which effectively makes overclocking these standard chips impossible. It may still be possible to push the BLCK up a few MHz, but without the extra
stepping and gearing ratio options, the other component clockspeeds based off that same base clock are going to go out of spec and will become unstable fairly quickly as you try to push that BLCK up.
There is one saving grace for enthusiasts considering a non-K part, however. The standard non-K CPUs will have Intel's latest TSX extensions and enterprise virtualization technologies enabled.
Although quite the head scratcher, Intel has decided to disable TSX, vPro, and VT-d on the unlocked K edition chips. The TSX extensions are not widely used yet, but will provide a noticeable performance boost to future programs that do take advantage of them by allowing developers to essentially mark off sections of code that can be run independently, and thus increase the multi-threaded-ness of the application by running as much code in parallel across multiple cores as possible. Further, the vPro and VT-d features are used by virtual machine applications (with VT-d being more relevant to the consumer side of things).
In short, Intel has continued to lock down and artificially limit its chips, as many enthusiasts suspected would happen. Standard non-K Haswell processors are more locked down than ever, and even the premium unlocked K CPUs suffer with the (odd) removal of TSX and virtualization support. As Mr. Gasior points out, enthusiasts are going to be faced with an odd choice where they can either spend extra money on a premium K part that will overclock but is limited in other ways, or go with the lower cost part that has all of the ISA extensions and virtualization support turned on... but is not overclockable.
In my opinion, locking down the standard chips is one thing-- Intel needs to incentivize enthusiasts to go with the more expensive (~$25 premium) unlocked K processors some how -- but if those same enthusiasts are spending extra money for a premium chip, they should get all the features the accompanying non-K SKU has as well as overclocking.
What do you think about the artificial limitations placed on the various Haswell SKUs?

With the launch of Intel's Haswell processor, accessory maker-turned notebook vendor Razer announced a pretty slick machine, the Blade. Based on a quad-core, 37 watt Core i7 Haswell CPU and a GeForce GTX 765M GPU, the Razer Blade packs a lot of punch.
It also includes 8GB of DDR3-1600 memory, an mSATA SSD and integrates a 14-in 1600x900 display. The design of the unit looks very similar to that of the MacBook Pro but the black metal finish is really an attractive style change.
The embedded battery is fairly large at 70 Whr and Razer claims this will equate to a 6 hour battery life when operating non-gaming workloads. With a weight just barely creeping past 4 lbs, the Razer Blade is both portable and powerful it seems.
The price tag starts at $1799 so you won't be able to pick one of these up on the cheap, but for users like me that are willing to pay a bit more for performance and style in a slim chassis, the Blade seems like a very compelling option. There are a lot of questions left to answer on this notebook including the thermal concerns of packing that much high frequency silicon into a thin and light form factor. Does the unit get hot in bad places? Can the screen quality match the performance of Haswell + Kepler?
We are working with Razer to get a model in very soon to put it to the test and I am looking forward to answering if we have found the best gaming portable on the market.

As Scott covered earlier this week, Apple quietly announced an update to the MacBook Air line along side the headline-grabbing Mac Pro redesign preview. Being a MacBook Air user for the past 2 years, I decided it was time to replace my Sandy Bridge-based model with some new Haswell goodness. Today marked the first day of retail store availability, and I picked up an 11" model with 256GB SSD.
Naturally, when I got back to the office there was only one route to take, installing Windows and disassembling it. While Anand uncovered the fact that these MacBooks were hiding a new unadvertised option, in a PCI-Express based SSD, I wanted to check it out for myself.
When I did some digging, I discovered that while Anand found a Samsung based SSD in his MacBook, mine actually contained a model by Sandisk. I did a quick initial benchmark in OS X, and proceeded to inspect the hardware itself.

Tagged: power supply, ocz, haswell, c7, c6
OCZ recently posted a list of its power supplies that are fully compatible with Intel's new 4th Generation Core "Haswell" CPUs and their new C6 and C7 processor sleep states. The new sleep states can draw as little as 0.05A from the 12V rail, and not all power supplies (especially older models) were built with that use case in mind. Somewhat paradoxically, as power supplies have ramped up in Wattage and power delivery characterists, other PC internals have started moving in the other direction towards increased power efficiency and lower power usage overall.
OCZ seems well prepared for Haswell, however, with a number of PSUs that are already fully compatible with Haswell CPUs. Even going as far back as its Z Series which launched in 2009 are compatible, which is comforting.
The full list of Haswell compatible OCZ power supplies is available below.
MK III Silencer
MK II Silencer
Fatal1ty Gaming Series
Z Series (EOL)
With that said, even if your OCZ (or PC Power & Cooling) power supply is not on this list, it will still work in systems that utilize Intel Haswell processors. However, you will not be able to take advantage of the new power sipping C6 and C7 sleep states.
As the launch of Haswell approaches, more and more PSU manufacturers are releasing compatibility information. So far, the following companies have put together compatibility lists.

Following Intel's announcement of new Haswell sleep states, various power supply manufacturers have released compatibility lists detailing which PSUs are able to deliver the low load necessary to support the power sipping sleep states on the 12V rail (which has not been much of a concern until Haswell).
One such PSU manufacturer was Seasonic, who has quite a few Haswell-ready power supplies across several lineups including its Platinum, G, and M12II series, among others. Included in that compatibility list were two new power supplies that Seasonic is showing off at Computex this week: the Seasonic Platinum 1200 and Seasonic M12II Bronze Evo Edition.
SeaSonic Platinum 1200
The Platinum 1200 is a high-end modular power supply that is capable of powering beefy multi-GPU setups. It is 80+ Platinum rated and is up to 92% efficient at 50% load.
Sesonic M12II Bronze Evo Edition
The Seasonic M12II Bronze Evo Edition is an updated version on past models and includes two SKUs that come in at 750W and 850W. It is a fully modular unit with flat black cables and fan control tech. It is 80+ Bronze and Energy Star rated, and is compatible with Intel's 4th Generation Core processors.

Intel had a host of new technologies to show off at Computex this year, starting of course with the Haswell processor launch. Hopefully you have read our review of the Core i7-4770K LGA1150 CPU already but thanks to some video sent our way, we have other interesting bits to share.
Below you will see Intel demonstrating four new products. First is the Acer Aspire S7 using a Haswell dual-core platform playing back 4K content. Next up is an Ivy Bridge tablet that is running completely fanless (passive) thus generating no noise at all while still offering impressive CPU and graphics performance. Intel then pulls a Lenovo K900 Android smartphone out of its pocket powered by the Clovertrail+ enabled Atom Z2580 SoC. Finally, we get a sneak peak at the next-generation of SoC designs with a look at a Silvermont-based Baytrail tablet running at 2560x1440.
