The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested
by Anand Lal Shimpi on January 3, 2011 12:01 AM ESTUEFI Support: 3TB Drives & Mouse Support Pre-Boot
Remember the mountain of issues I had trying to get Seagate’s 3TB HDD to work as a boot drive in my X58 system? A couple of weeks ago Intel released version 10.1 of its storage drivers, which added software support for drives larger than 2.2TB. That’s one piece of the puzzle. With Sandy Bridge, many motherboard manufacturers are moving to UEFI instead of traditional 32-bit PC BIOSes. Combine that with a GPT partition and your new Sandy Bridge system should have no problems booting to and accessing 3TB drives made of a single partition.
ASUS' entire SNB lineup is UEFI enabled
ASUS sent over a couple of its 6-series motherboards which boast a custom skinned UEFI implementation. You get all of the functionality of a traditional BIOS but with a GUI, and yes, there’s full mouse support.
You’re either going to love or hate the new UEFI GUIs. They do take a little time to get used to but pretty much everything is where you’d expect it to be. Navigating with the mouse can be quicker than the keyboardin some situations and slower in others. Thankfully the interface, at least ASUS’, is pretty quick. There’s scroll wheel support although no draggable scroll bars, which makes quickly scrolling a little frustrating.
Unlike P55, you can set your SATA controller to compatible/legacy IDE mode. This is something you could do on X58 but not on P55. It’s useful for running HDDERASE to secure erase your SSD for example. If you do want to use HDDERASE on a 6-series motherboard you’ll need to first run HDDERASE4 to disable the UEFI initiated security on your drive and then run HDDERASE3 to secure erase it.
The biggest improvement to me honestly is POST time. Below is a quick comparison of time from power on to the Starting Windows screen. I’m using the exact same hardware in all three cases, just varying motherboard/CPU:
| Intel P67 | Intel P55 | Intel X58 | |
| Time from Power on to Boot Loader | 22.4 seconds | 29.4 seconds | 29.3 seconds |

There is the Z67 chipset which will allow both overclocking and integrated video. However, this chipset won't arrive until Q2.Tanel - Monday, January 3, 2011 - link
Well, yes, but one wonders who came up with this scheme in the first place. Q2 could be half a year from now.teohhanhui - Monday, January 3, 2011 - link
I've been thinking the same thing while reading this article... It makes no sense at all. Bad move, Intel.micksh - Monday, January 3, 2011 - link
Exactly my thoughts. No Quick Sync for enthusiasts right now - that's a disappointment. I think it should be stated more clearly in review.Another disappointment - missing 23.976 fps video playback.

Yeah, OK, lack of support for VT-d ostensibly sucks on the K parts, but as previously posted, I think there may be good reasons for it. But lets look at it objectively...1. Do you have an IO-intensive VM workload that requires VT-d?
2. Is the inefficiency/time incurred by the lack of VT-d support egregious?
3. Does your hypervisor, BIOS and chipset support VT-d?
IF you answered "NO" or "I don't know" to any of those questions, THEN what does it matter? ELSE IF you answered "YES" to all of those questions, THEN IMHO SB isn't the solution you're looking for. END IF. Simple as that.
So because you--who want that feature and the ability to OC--which is likely 0.001% of the customers who are too cheap to spend the $300-400 for a real solution--the vendor should spend 10-100X to support that capability--which will thus *significantly* increase the cost to the other 99.999% of the customers. And that makes sense how and to whom (other than you and the other 0.0001%)?
IMHO you demand a solution at no extra cost to a potential problem you do not have (or have not articulated); or you demand a solution at no extra cost to a problem you have and for which the market is not yet prepared to offer at a cost you find acceptable (regardless of vendor).

General best practice is not to feed the trolls - but in this case your arguments are so weak I will go ahead anyway.First off, I like how you - without having any insight in my usage profile - question my need for VT-d and choose to call it "lets look at it objectively".
VT-d is excellent when...
a) developing hardware drivers and trying to validate functionality on different platforms.
b) fooling around with GPU passthrough, something I did indeed hope to deploy with SB.
So yes, I am in need of VT-d - "Simple as that".
Secondly, _all_ the figures you've presented are pulled out of your ass. I'll be honest, I had a hard time following your argument as much of what you said makes no sense.
So I should spend more money to get an equivalent retail SKU? Well then Sir, please go ahead and show me where I can get a retail SB SKU clocked at >4.4GHz. Not only that, you're in essence implying that that people only overclock because they're cheap. In case you've missed it it's the enthusiasts buying high-end components that enable much of the next-gen research and development.
The rest - especially the part with 10-100X cost implication for vendors - is the biggest pile of manure I've come across on Anandtech. What we're seeing here is a vendor stripping off already existing functionality from a cheaper unit while at the same time asking for a premium price.
If I were to make a car analogy, it'd be the same as if Ferrari sold the 458 in two versions. One with a standard engine, and one with a more powerful engine that lacks headlights. By your reasoning - as my usage profile is in need of headlights - I'd just have to settle with the tame version. Not only would Ferrari lose the added money they'd get from selling a premium version, they would lose a sell as I'd rather be waiting until they present a version that fits my needs. I sure hope you're not running a business.
There is no other way to put it, Intel fucked up. I'd be jumping on the SB-bandwagon right now if it wasn't for this. Instead, I'll be waiting.

Apologies, didn't mean to come across as a troll or in-your-face idjit (although I admittedly did--lesson learned ). Everyone has different requirements/demands, and I presumed and assumed too much when I should not have, and should have been more measured in my response.You're entirely correct to call me on the fact that I know little or nothing about your requirements. Mea culpa. That said, I think SB is not for the likes of you (or I). While it is a "mainstream" part, it has a few too many warts..
Does that mean Intel "fucked up"? IMHO no--they made a conscious decision to serve a specific market and not serve others. And no, that "10-100X" is not hot air but based on costing from several large scale deployments. Frickin amazing what a few outliers can do to your cost/budget.

I didn't have time to read all reviews, and furthermore I am not sure I will be able to express what I mean with the right nuances, since English is not my first language.For the moment I am a bit disappointed. To account for my relative coldness, it is important to explain where I start from :
1) For gaming, I already have more than I need with a quad core 775 and a recent 6x ati graphic card.
2) For office work, I already have more than I need with an i3 clarkdale.
Therefore since I am already equipped, I am of course much colder than those who need to buy a new rig just now.
Also, the joy of trying on a new processor must be tempered with several considerations :
1) With Sandy Bridge, you have to add a new mobo in the price of the processor. That makes it much more expansive. And you are not even sure that 1155 will be kept for Ivy Bridge. That is annoying.
2) There are always other valuable things that you can buy for a rig, apart from the sheer processor horsepower : more storage, better monitor...
3) The power improvement that comes with Sandy Bridge with what I call a normal improvement for a new generation of processors. It is certainly not a quantum leap in the nature of processors.
Now, there are two things I really dislike :
1) If you want to use P67 with a graphic card, you still have that piece of hardware, the IGP, that you actually bought and that you cannot use. That seems to me extremely unelegant compared to the 775 generation of processors. It is not an elegant architecture.
2) If you want to use H67 and the Intel IGP for office work and movies, the improvement compared to clarkdale is not sufficient to justify the buying of a new processor and a new mobo. With H67 you will be able to do office work fluently and watch quasi perfectly, with clarkdale you already could.
The one thing that I like is the improvement in consumption. Otherwise it all seems to me a bit awkward.

Well, the IGP non being removable is like having on-board sound, but also having a dedicated soundcard. Not much of a deal, since you can't buy a motherboard withou integrated sound nowadays...Shadowmaster625 - Monday, January 3, 2011 - link
You say you want Intel to provide a $70 gpu. Well, here's a math problem for you: If the gpu on a 2600K is about 22% of the die, and the die costs $317 retail, then how much are you paying for the gpu? If you guessed $70, you win! Congrats, you now payed $70 for a crap gpu. The question is.... why? There is no tock here... only ridiculously high margins for Intel.
