Core i7-4770K: Haswell's Performance, Previewed
Intel Haswell desktop CPUs are available for pre-order

Hexus

The run-up to any technology launch is rife with rumors and speculation, and Haswell is no different in this regard. The folks over at Tom's have managed to snag a pre-production Haswell chip and have run some numbers.

Summarizing Tom's performance findings, the pre-production Core i7-4770K is generally between five and 10 per cent faster than a Core i7-3770K for CPU-intensive benchmarks, and understanding that both chips operate at the same speed, the gains are related to architecture improvements.

But the biggest generation-to-generation improvements are to be found in the performance of the chips' on-board 'GT2' graphics. The 4770K's HD Graphics 4600 IGP is between 10 and 50 per cent faster than the 3770K's HD 4000 Graphics, with the improvement very much dependent on title.

Tom's commits a minor faux pas by not including numbers for an AMD Trinity-based APU's graphics in the graphs, though does mention them in passing in the text. The A10-5800K's IGP is 10-25 per cent faster than the new-and-improved HD Graphics 4600, the author notes. However, we know that some mobile-orientated Haswell chips will feature beefed-up 'GT3' HD 5xxx graphics, though we're unlikely to see them present for desktop parts.

Unfortunately, there are no numbers for power consumption, which would be interesting to see, and we have to take the performance of any pre-production chip, using beta drivers, on a new motherboard, with a large pinch of salt.

Indeed, the 4770K's HD Graphics 4600 IGP is between 10-50% faster than the 3770K's HD 4000 Graphics, with the difference apparently contingent on specific game titles. Meanwhile, the A10-5800K's IGP is 10-25% faster than the HD Graphics 4600.

Intel Haswell 4th Generation Core processors gain GPU optimizations
Quote:
Building on top of the existing DirectX 11.1 development language, Intel has created two driver extensions that are designed specifically to take advantage of the GPU found inside 4th Generation Core processors. The first, PixelSync, allows game creators to create effects using Order Independent Transparency - one of the "Holy Grails of real time graphics" according to Huddy.

By sending data through the pixel pipeline in a specific order, rather than randomly, it's possible to render more realistic smoke, hair, windows, foliage, fences and other complex geometry without the huge computational overheads needed to do so using random data. According to Intel, enabling OIT results in a 10% performance hit, versus 80% on traditional graphics cards.

The first developer to take advantage of PixelSync is Codemasters, adding OIT effects to racing simulation Grid2. Apparently, having accurately lit glass, smoke and dust is a feature that was high on the wish list for the company, but until now had proved impossible.
“The artists working on Grid2 have been requesting this type of effect for years, and prior to this, it wasn’t possible to achieve it at a reasonable cost,” Clive Moody, senior executive producer at Codemasters Racing, said of PixelSync. “The fact that this capability will be available to millions of consumers on forthcoming 4th generation Intel® Core™ processors is very exciting to us.”

Creative Assembly, developer of Total War: Rome 2, have also committed to using PixelSync in its games, alonhg with the second Intel-exclusive technology; InstantAccess. This driver extension lets the CPU and GPU access the same shared memory without having to go through the DirectX API. By avoiding comparatively slower PCI-Express bus, games played using the integrated GPU should see less texture stuttering when loading levels, along with a smoother overall experience and less micro-stutter during gameplay.

Of course, to use either one of these new technologies will require a PC running a 4th Generation Core processor. It also won't be able to use a dedicated graphics card, as the optimisations are tied to Intel's graphics driver. Huddy assured us that Grid2 was running at between 40-50fps on Intel hardware, although he made no mention of resolution or detail settings. We'll have to wait until later in the year, when Haswell officially launches, to put the new GPU through its paces.

Known issues:
Intel Haswell to arrive in low volume until USB 3.0 issue is fixed
Intel to Slowdown Ramp of Core i “Haswell” Platform Before New Chipset Stepping Is Ready
Quote:
Although Intel Corp. is on track to introduce its next-generation Core i-series “Haswell” microprocessors for desktops and notebooks in June, the company will limit the amount of microprocessors and mainboards on the market because of the recently transpired glitch with USB 3.0 before it fixes the issue. A financial analyst believes that delay of strong volume ramp of Haswell will further negatively impact PC market.

“Haswell for desktop (Denlow platform) looks set to launch with cautious volume in June using the faulty C1 stepping, and then to see a stronger ramp once the glitch is worked out. Still, this is more than we had hoped for in June. Caution in Ivy Bridge units still likely to constrain gross margin for Intel and contacts point to August as the more significant launch period,” said JoAnne Feeney, an analyst with Longbow Research, in a note to clients, reports Tech Trader Daily.

Earlier this month it was reported that Intel began to inform its partners that when a PC system with Core i-series “Haswell” and 8-series chipset inside wakes from S3 sleep mode, it experiences issues with devices connected through USB 3.0. Intel seemingly defines the issue only as a nuisance for end users, as there would be no serious unpleasant consequences, such as data loss. A quick fix for the problem, which may result in blank PDF pages or failure to resume playback, is already known: a restart of applications. In order to solve the issues with USB 3.0, a new chipset revision is required.

X99:
Intel X99 Chipset For HEDT Platform In The Works?
Quote:
With Intel’s Haswell and Ivy-Bridge-E platform nearing their launch, interesting rumors are starting to pop up all over the place. The latest bit by Tweaktown indicates possibility of a successor to the X79 chipset currently powering Intel’s Sandy-Bridge-E processors.
ntel prepping a successor to the X79 chipset comes as an astounding piece of info, considering everything pointed for a recycle of the chipset with Ivy-Bridge-E. The X99 chipset which is not yet confirmed will succeed the X79 chipset and will power Intel’s upcoming Ivy-Bridge-E platform. The motherboard will use the same LGA 2011 socket allowing compatibility with Sandy Bridge-E CPUs. But that’s not all of it, Tweaktown also claims Intel might scrap the Ivy-Bridge-E platform all-together and instead launch Haswell-E processors this year. I know, it sounds crazy considering Intel’s two months old roadmap marked the release of Ivy-Bridge-E processors during Q3 2013. We can’t say for sure how much truth Tweaktown’s report holds. Only time will tell.
Intel-CPU-Roadmap-2013_1-635x391_zpsc68457fb.jpg
Additionally, Tweaktown also brings along some believable info along the crazy ride. Tweaktown reports that Intel will reveal their Z87 Haswell motherboards on Computex. Possibility remains that some manufactures might just showcase them at the CeBIT 2013 starting from 5th March. Intel’s upcoming 8-Series Lynx Point based motherboards have already been thoroughly detailed along with their Haswell CPU counterparts. Although it is to be noted that the Z87 Haswell motherboards would be the last socket based motherboards from Intel. With the launch of Broadwell in 2014, Intel will completely transition from LGA socket based processors to BGA packages. BGA would seriously limit any upgrade-ability of motherboard or processors due to the CPU soldered on the motherboard itself.
BGA packages will certainly be a ‘new’ to Intel. But we can’t help but wonder if it will be successful or not, considering today’s pace we’d say otherwise. There is always AMD to rely to as they have promised to support socket based processors for quite sometime. The upcoming Richland based APU’s also look quite promising. It is still too early to draw out conclusions. Only time will tell how well Intel or AMD fare.
Tweaktown

Will keep updating when good info hits the net..
Cheers.

Nice compilation of Haswell news thumb.gif

Could anyone tell me why tsx is disabled on k series CPUs though? Seems like a bit of a cheap shot by Intel, or am I missing something?

I just want to know how soon Laptop's will be shipping with Haswell. Power consumption is allegedly the best gain for Haswell.
