Updated: Intel Haswell chips power the next generation of Apple products

It's official: Apple's next-generation Macbook Pro range will sport Intel's Haswell chipset, launched in June. Promising giant leaps in power effiencey and overall performance, the chipsets utilise a newly designed architecture and are manufactured using the 22nm process.

Here's everything you need to know about Intel Haswell. 

The chips

The mobile processors will come in four varieties, and will have different capabilities depending on their suffix.

H – The quad-core processors will have Intel’s highest graphics capabilities available – dubbed Iris Pro (5200).

M – Theset raditional 2-chip models which will be available in quad-core/dual-core varieties.

U – Designed specifically for Ultrabooks – these System-on-chip (SoC) processors will available in either 28Watt or 15Watt varieties. The 28W chip will have the highest available Iris Pro (5200) graphics capabilities and the 15Watt chips will have the Iris graphics (5100).

Y – The lowest power Core-based processor will also have a System-on-chip design and will be designed for detachable products.

UPDATE: 18/06/2013

Leaked slides from Intel show that it plans to launch an unlocked desktop range known as the Haswell-E series.

According to the documentation obtained by, these will be the first chipsets to to use 6- and 8-cores, as opposed to just 4 cores. Power users will be able to overclock the chips out-of-the-box and reports suggest the chips will be between a 33 – 50 per cent faster than it predecessor.

With heavy duty processing power on board, the E-Series range will need to be supported by discrete graphics. The slides from Intel suggest that the processors will each support up to four graphics cards.

Intel has also drip fed information about its forthcoming Wellsburg motherboard. This will support four-channel DDR4 RAM for the first time, with a clock speed of 2133 MHz. Combined together, the E-series processor, DDR4 RAM, and  Wellsburg motherboard will be able to power up to 10 SATA hard drives transferring data at up to 6Gbps, and support a total of 14 USB ports (six USB 3.0 and eight USB 2.0).

Battery life

The chipmaker claims Haswell will bring the biggest improvement in battery life Intel has ever produced.

Haswell chips will have 3 power states, compared to two in its predecessor, Ivy Bridge. These will be Active, Sleep, and Active Idle. Intel claims the advanced power saving will help give it at least 20x power consumption improvement over third generation chips.

Intel claims its flagship Core i7-4650U processor with uses 15W of power will provide up to 9 hours of HD video playback. This is three hours longer than its equivalent Core i7 processor from the previous generation.

The 4th generation Core processors will be able to support Ultra HD displays – also known as 4K. This will be four times clearer than current HD. 4k has over 8 million individual pixels (3,840 x 2,160) compared to about 2 million for HD (1,920 x 1,080).


Intel has confirmed that graphics performance will be double that of the previous generation.

Tom’s Hardware benchmarked a high-end Core i7-4770K part ahead of launch, comparing it to the previous generation Ivy Bridge.

In the various tests, Haswell showed significant improvement when it came to gaming, but commonly used tasks such as converting video, music and documents didn't show too much of an increase.



Haswell chips will power servers and desktops as well as next-generation Ultrabooks. HP is one of the first manufacturers to unveil devices running the chipset.

The TouchSmart 14 Ultrabook that will be available with an optional 14in 3,200 x 1,800 display, placing it head-to-head with the likes of the Chromebook Pixel and the MacBook Pro with Retina Display. 

Meanwhile, the Envy 17 will pack a 17.3in screen with 1,920 x 1,080 resolution, 2TB of storage and four speakers with Beats Audio.

Meanwhile, Dell has announced its T1700 Workstations will be powered by the Haswell Xeon E3-1200 chipset, support for up to 32GB of EEC memory and 4 DIMM slots. Users will be able to choose between one 3.5in SATA disk or two 2.5in SATA disks.

Despite the small chassis, Dell has packed in a range of ports onto the T1700. The front will include 2 x USB 2 and 2 x USB 3 ports. The rear will pack 4 x USB 2 and 2 x USB 3 as well as 2 x PS2, 2 x DisplayPorts, 1 x VGA and 1 x RJ45 connections.

Haswell is also expected to be used in a variety of hybrid designs, and it is likely to show up in Microsoft’s Surface Pro 2.

Release date

Speaking at Intel’s Developer Forum in Beijing, Kirk Skaugen, general manager of the PC client group at Intel confirmed the processors will start shipping in Q2.


Online vendors such as The PC SuperStore have put up a price list for Core i5 and i7 parts. Prices range from $197 for the Core i5 4430 to $368 for the high-end Core i7 4770K.

Will Haswell boost Ultrabook sales?

Ken Dulaney, vice president and distinguished analyst at Gartner told IT Pro that Haswell chips are unlikely to boost the sale of Ultrabooks.

"The problem with PC sales is that there are a) alternative product categories and b) there really isn’t a new application category that will drive sales of Ultrabooks/notebooks at lifetimes that are shorter than the standard 3 – 4 years," he said.

"So people will buy an Ultrabook when they have to but the problem is that people don’t need a notebook refresh that soon, especially as more systems move to the browser. And poor marketing of Windows 8 has hurt."

"4K video (3840 x 2160 resolution), which is a four times the resolution of current HD."

(1920 x 1080) x 4 = (7680 x 4320)

might wanna think about that one again

Actually, resolution is given by the total number of pixels.

For example, a 4x4 display (16 pixels) would have four times the resolution of a 2x2 display (4 pixels).

1920x1080 = 2073600
3480x2160 = 8294400 = 2073600 x4


haha.. Maybe u can start think now.. :D

Nice response Cristian! Didn't grind him into a fine powder, just informed him of his mistake. I love it!!

idiot !

Are you stupid .... you dont work out like that . its 2 x the width and 2 x the heigt . which equals 4 x . not 4 x each thats 8 x. people make me laugh when they try so hard to look right

4K UHD is a resolution of 3840 pixels × 2160 pixels (8.3 megapixels, aspect ratio 16:9) and is one of the two resolutions of ultra high definition television, the other being 8K UHD which is 7680 pixels × 4320 pixels (33.2 megapixels). Both are aimed at consumer televisions. 4K UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.[1]... Straight from the wiki... I think Andrew .aka stupid should edumicate himself a little before he responds to articles...

OMG! i am such an idiot i posted here your all noobs and can't undertand what i am telling you i am an expert when it comes to resolutions!

But then again Marketing referred to the Vertigo Lines in 1080p and 720p so why has it changed to now horizontal? 4K really should be 7680 x 4320 and 3840 x 2160 should be 2K.

8x you say? I believe it is 16x. The person essentially multiplied by 4, twice, which would be 16.

Let's check it:

Reference Value: 7680 x 4320 = 33,177,600

1920x1080x8 = 16,588,800

1920x1080x16 = 33,177,600

wtf what is up with all this pixel talk!

I'm getting confused. Can some one please make a list of which of the posters above are idiots? Because people seem to be saying different things.

Look at the one who have more 'likes'

Christian is right with 4k(@16:9 resolution?)
1920x1080 = 2073600
3480x2160 = 8294400 = 2073600 x4

(And i guess when tvscreens will have the same, they would then call it 2160p?)

Last comment on the article is wrong, when we get tired of tablets, we will move back to ultrabook convertibles.

Problem is, you are full of it. No expert or professional (which I happen to be) would ever claim that the following is 4x the resolution of HD.

(1920 x 1080) x 4 = (7680 x 4320)
Everyone and I mean everyone who is an expert or better in the field knows that what you gave is a 16x increase not a 4x increase.

That would make sense but 4k just sounds better to the marketing people!

What you quoted is not 8K but 16K. Do not forget that you are multiplying BOTH the number of pixel in both the x and y axis by 4, which results in a 16 times multiplier. To get 4 k, you will only multiply both the pixel resolution along the length and width of the monitor by 2 each - 2x2 = 4. To get either times, you actually have to multiply it by 2.8284271 ... each

you sir, are correct. In fact, this is a common error when the primary school and secondary school kids tries to learn mensuration and was tasked to calculate the increase in area/volumn (in which case it will be a cube instead of square of the increment, assuming the increment is the same on all side) of a shape/form.

Now, that is common sense, isn't it? But since when has marketing and finance been about common sense?

Are you talking to me hohopig???

Your description an math are off... if I need to provide any more proof beyond your standard wiki.. head to any manufacturer site and look at the specs of a up coming 4k tv.... Go to sonys site for instance....

do not hold me to it... but pixel density and resolution do not always go hand in hand... Look at apples screens for example.... They have (until recently), The highest pixel to resolution ratio out there. But yet maintain the industry standard resolution..... The industry standard for 4k is what I originally said and for 8k as well... If manufacturers would like to come up with a process to improve on this standard.. then so be it... but just to let ya know... that is the rez of 4 and 8k... believe in da wiki...

Man what is so hard to understand about this if you double you length and width you increase your area by four times not two.

a x b = ab

2a x 2b = 4ab


1920 x 1080 = 2 073 600 pixels

3840 x 2160 =8 294 400 pixels ....

resolutions is measured in number of pixels. the screen resolution you quote will have 16 times as many pixels not 4

3840 pix ~ 4k
7680 pix ~ 8k


you will never understand me only few lucky people have a wise brain like me, Guys HD is high division UHD is upper high division so according to that 4K is 4000UHD/HD this gives (3840x2160)/(1920x1080)=2x therfore 4k is actually 2k. got it now douche bags!

No it's due to the fact that doubling the length and doubling the height is 2x2 for 4k. Think of a square face with 2 boxes across and two down (so 2 by 2 thus 4 total). Now double each side (4 by 4) there is 16 boxes total now not 8.

type (3840x2160)/(1920x1080) in a calculator it's 4

3840x2160 is actually 4k resolution or 2160p
dont confuse 4320p with 4k, 4k =2160p, 8k=7680x4320

4k" refers to the horizontal resolution not the area 3840 ~ 4k(yes it's off but, I guess the cinema 10:19 aspect ration would make it 4096 which is a little bit closer to 4k)

2160p and 4320p isn't advertised from what i see, only in tv forums by some users

In Summary:
Full HD = 1920x1080=1080p
4k Ultra HD = 3840x2160=2160p
8k Ultra HD = 7680x4320=4320p

no one is claiming that 4k HD means 4x the area, it is the vertical and horizontal resolutions that is being referenced, not the area

it is 4x the area btw, but 4k refers to horizontal pixels (badly rounded but still...)

please dont call people stupid, it's not nice (especially if you're wrong lol)
4k resolution refers to horizontal resolution, and it happens that 4k = 4x the area(1920x2=3840 horizontal pixels), but with 8k=16x the area (4x1080=7680 horizontal pixels)

yes it's a pretty bad approximations, but it's the marketing they came up with

it's based on horizontal resolutions (3840~4k), 4k happens to be 4x the resolution of 1080p, but once u get to 8k, it's 16x the resolution (7680 horizontal resolution)

you dont have to be rude to prove your smart your highness.

You are a rude person !
Very UGLY comments only prove you are a FOOL !
