Woohoo, my computer is slowly dying so it will need replacing in the near future. Hopefully the desktop parts will be out by then.

Some overclocking info about Ivy Bridge:

Ivy Bridge has been officially announced today. Can't wait to see the benchmarks!

Umm... go see the reviews that Jeff posted?

That last one is Intel Insider, and it is a horrendous step backward for Ivy Bridge, and Sandy Bridge before it. Basically it spends power and time to encrypt everything on the system buses. It is useless work, lessened battery life, and the only reason it is there is to placate the content MAFIAA.
To make matters worse, Intel Insider is not user controllable, it is only controllable by unnamed remote 3rd parties who can now do things to your system that Intel won’t list. Seriously, think about the security implications, you are giving an unknown list of entities that are proven to be hostile to users the right to silently deny you use of your computer. They can potentially put things on your PC, take things off, and do so in a way that you can’t control, avoid, or worst of all detect. This ‘technology’ is actively harmful to the owner, and enough of an issue that I suggest that you avoid Ivy Bridge until it is not just fully documented, but user controllable. Scary on a whole new level.

One thing I haven't been able to find info about is "Intel OS Guard". Any ideas there? It sounds bad.
Edit: Here are two particularly useless quotes. No actual info yet.

Quote:

New security features include Intel OS Guard, which prevents malware attacks on Windows 8 and some Linux distributions

Quote:

Intel OS Guard helps defend against privilege escalation attacks where a hacker remotely takes over another person's system.

(The second quote is clearly meant for the clueless masses.)

It seems that if you wanna go for "maximum kicks in the butt per ingested watt" the ivy-3770K would serve you better, but if you are targeting the performance (and don't mind about cost and killed watts) then sbe-3960X is still the king (I have yet to put my hand on one of those, never touched one, I tested a sbe-3820 some time ago but the performance was lousy compared to sb-2600k), and if you want to get the best price/performance, then sb-2600k is still the best by far (eventually a 2700k, but the only difference to 2600k is the clock a bit higher, for a higher price).

Per number of cores, like either buying 3 times ivy-3770k or buying 2 times sbe-3960X (to get the same number of 12 cores, as you can't really compare a 4-core with a 6-core), then you get a better deal with ivy, considering you would have 3 systems (three times the bus width, plus: if one crashed you still have 66% of the farm producing, contrary to 50% for sbe, etc) for about half of the price (the 3960x is still bloody expensive!) and about 70% of power consumption.

If you don't need a compute right now, in this very right moment, then I would recommend to wait for a while, few months. Some 6 cores or 8 cores ivy stuff should pop-up under (or around) 500 bucks. Then we could really compare, i.e. we would have the same number of cores as a 3960X, or more, maybe the same bus, for half of the price and 60% power (heating elements).

edit: and there is no hardware virtualization for 3770k???? Grrrrr....

I'm not sure how you got there, but the 3770K is around the same price as the 2600K, and less than a 2700K, while getting slightly more performance. The 3770K is king in both performance/watt and price/performance.

Memory scales nicely -- frequency is directly correlated with bandwidth.
http://www.tomshardware.com/reviews/...k,3181-10.html

Quote:

A synthetic like Sandra 2012 demonstrates sizable gains. Bandwidth literally doubles as we move from two channels of DDR3-1066 to DDR3-2133. <snip> Real-world performance improvements trail off a lot faster though, likely because memory isn’t the most debilitating bottleneck.

Since of course for v27+/AVX memory is the most debilitating bottleneck, we might see some returns even moving from 1866->2133. Has any one actually managed to acquire one, or are we all out of money?

For Bdot:

Quote:

HD Graphics 4000, on the other hand, supports FP32/FP64 under DirectCompute and FP32 in OpenCL. Intel currently lacks Khronos certification for ARB_gpu_shader_fp64, so it’s not enabled.

http://www.tomshardware.com/reviews/...0k,3181-6.html
However, in the AnandTech review that Jeff posted, I got the impression that OpenCL 1.1 wasn't initially supported.

It's SMEP (Supervisor Mode Execution Protection) in disguise

Cool! Thanks. A quick Google brings up http://vulnfactory.org/blog/2011/06/...t-it-on-linux/, by way of http://forums.overclockers.com.au/sh...d.php?t=964305.

Ok,
The integrated GPU improvements are less important on desktop system. (Add card instead)
The Ivy Bridge is the last LGA 1155 socket processor
The power improvements of Ivy Bridge are less important on the desktop.

It sounds to me like Ivy Bridge is better as a mobile upgrade and that a large desktop investment should wait for the LGA 1150 socket.

I just bought an i5-3570k on sale at Microcenter today. Put together the cheapest build I could (under $400--plus some parts I had sitting around) I don't know what numbers you guys actually want to see.

It's doing a double check @ .010 seconds per iteration.
and running a couple P1's
and an LL of a 56 million number @ .021 seconds per iteration.

temps are stable with intel's stock air cooler. I played with the Gigabyte auto-overclocker application a bit, but it didn't seem to improve times much.
