Hmm. Hard to say for sure. A little lacklustre in terms of absolute performance. And already been seeing rather flakey reports where overclocking is concerned.

On the other hand, from my SB rig, a few bonuses. More Sata6 ports + twice the bandwidth between the chipset and the CPU could make it fun to play with more than 2 SSD's in a Raid 0 setup.

Just rememberd this from another thread:
The flaw is not really a big flaw. It only effects - reportedly - effects USB 3.0 devices which are attached when you put the system 'to sleep'. Restart any progs that mess up is the short term solution...and thats the scope of the problem. It shouldnt - reportedly...from what I heard - effect USB 2 devices. So as long as you dont leave your USB 3 stroage drive plugged in...and / or make sure to save your work before before putting the system into low power mode....you will be fine...or atleast that is what I have heard. Wont know for sure UNTIL it lands...but thats what I have heard :)
How about any issues regarding this and anything else you may find that can be found and adding them to the summary?

I'm all for new toys, but not enough of a performance jump from SB to be worth it in the workloads that i do care about.

Is it at all possible that the integrated graphics into the Sandy Bridge, Haswell, etc platforms are part of why processor speed hasn't really seemed to significantly increase? I don't think it's as simple as 'it's taking horsepower space on the chip', but I'm curious as to if it's part of why the clock speed increases haven't been dramatic, or if it's a matter of the limits of silicon, marketing or something completely different (I'm not particularly knowledgeable on the CPU structures, limits and inner workings).
A lot of the reasons why clock speed hasnt ramped can be boiled down to the fact that frequency isnt the limiting factor in making things run faster. That sounds like a hypocrisy, but its not; Somewhere else is usually the bottleneck, and not at the 'processing' level due to speed. It is referred to as "Transmission Delay" (or at least that is how it was relayed to me :biggrin:). This is why more cores started getting added. You can thus process more information in an equal time. For example, in perfect theory (and parallelism) it takes two cores at 2ghz to process the same amount of information as one core at 4ghz. This obviously doesnt take in to account a slew of factors that change this, but it gives a great idea.

In addition to that, there are also the physical limitations. Thermally, things get out of hand as clock speeds ramp up. Having transistors switch on and off (or going from 0v to 1v in real terms) takes time. Gate leakage in your transistors occurs. etc. Essentially we're limited by the properties of the silicon, and the laws of Physics.

The Prescott era processors were a great example of the problems with ramping clock speeds unduly, and the problems associated with it.

Ditto, sooo tempted.

Can't wait to see more on the overclocking (and the 4670k done too hopefully)


One thing I don't get is why you didn't include a 920 or even slightly older parts as I think these are the people that will be most likely to upgrade here?

I get you can't test everything and it add a butt load of work for every part you test against but I would have liked to have seen that much and the A series dropped when IGP wasn't being used.



Wasn't that an ASrock z87 fatality?
D'oh you are right! GAH! Now its three to choose from :bleh:

I guess you could always go back to the IB or SB reviews and then just scale the numbers roughly. Might not be a perfect comparison, but it shouldn't be amazingly far off.

Good points Sagath. I thought of thermals being an issue, but I never really considered transmission delay and the variety of components and activities that go into a CPU.

Nice review as always. No surprises for me anywhere.

As much as I don't really like the idea of BGA, I can say I am curious to see what the 3770R will be priced like (and how much the lower TDP will hold back its turbo).

Yea but I'm Laaazzzzzzeeeeeeee :p

I know I can but I then have to match the few tests that are the same and also it doesn't take into consideration any software based performance increase that the 920 or whatever may not have benefited from.. ie I'd be guessing

Great review Sky.

That said I will have to hold my opinion until I see what they are really capable of with regards to the OCing. I have had my [email protected] stable for ages and can even get it up to 5.1GHz on occasions. For me to even consider one of these I would have to be able to get at the least an equivalent OC.

Scrapping PCI, more SATA3 and USB3 is awesome. But honestly, that should've been done a generation ago.
But yeah, just your standard ~5-10% average increase in performance.

We need something more impressive... Come on AMD and your heterogeneous cores!
