A couple of articles giving an architectural and technical preview of Ivy Bridge

http://www.hardwaresecrets.com/article/ ... cture/1397

Features at a glance:

Socket 1155
PCI Express 3.0 controller, which increases the bandwidth of the PCI Express lanes connected to the CPU from 500 MB/s to 1 GB/s; motherboards must use PCI Express 3.0 channel chips, otherwise, the video card slots will be limited to 2.0 speeds
Two new security features: a digital random number generator and a Supervisory Mode Execution Protection (SMEP)
Float16 format conversion instructions, which convert between a 16-bit compressed floating point memory format and a 32-bit single precision format
Improved performance for instructions that handle strings (REP MOVSB and REP STOSB)
Four new instructions for allowing applications to access the FS and GS registers of the CPU
Support for DDR3L (i.e., low-power DDR3) memories in mobile CPUs
DirectX 11 graphics engine
New 2D graphics engine
Support for three video monitors
Memory overclocking limit was increased from 2,133 MHz to 2,800 MHz, and memory clock can be configured in 200 MHz increments now
Dynamic overclocking, allowing you to change the clock ratio on unlocked CPUs without needing to reboot the PC, and higher clock ratios (up to 63) available for unlocked CPUs
Improvements in power management
22-nm manufacturing process

It all sounds good to me and I look forward to being able to run one in my system.

Is IB still going to be 8x+8x PCIe bandwidth or have they finally allotted 16x+16x?

-- and it's about time for PCIe 3.0. Intel may have the CPUs but their MBs currently lack.

Depends on the motherboard iirc. Those that are capable of PCI-e 3 should be able to do 16x (due to the doubled bandwidth PCI-e 3 provides). PCI-e 2 motherboards will stay 8x

i have a feeling that it may be delayed a bit ..

i am thinking that i should contact Intel and ask for a SB sample. i can get a MB to review.
-- i am really curious how much different it will be in gaming compared to the AMD CPUs and i7-920

i am guessing that the only difference will come from increased clockspeed.
- from 3.8GHz to 4.4GHz or so. i bet there is no difference in 95% of the games except for clockspeed scaling
(just a guess .. i want to test this out and also test out vRAM in Videocards at 5760x1060)
:hello:

Intel Ivy Bridge CPU Names and Features Revealed
By Hilbert Hagedoorn, October 18, 2011 - 8:54 PM via soft-pedia

You'll need to wait another month or six but the first processors based on the Ivy Bridge architecture, details about these chips keep surfacing, the latest info has come to confirm the names Intel intends to use for these CPUs as well as some of their specifications.

Starting with the Core processor lineup, this will be split into the same i3, i5 and i7 series, but Ivy Bridge parts will carry the 3000 designation, just as is the case with the upcoming Sandy Bridge-E processors.

Pentium CPUs on the other hand, won't get the same 3000-series designation as their more powerful brothers, but will also move to a new naming scheme that used four digits instead of the usual three.

In addition to the new names, Intel has also operated a series of changes to the maximum TDP's of the processors as these now top at 77W compared to 95W in Sandy Bridge.

This TDP is common for both the high-end Core i7 and Core i5 parts, including the K-series unlocked CPUs.

The rest of the features were pretty much left unaltered so the same characteristics that made the difference between Core i7, i5, i3 and Pentium processors in Sandy Bridge SKUs are also used for Ivy Bridge parts.

Ivy Bridge is the code name used for the 22nm die shrink of the current Sandy Bridge chips and features basically the same architecture, but with a few minor tweaks and improvements.

This includes a new on-die GPU that will come with full DirectX 11 support as well as with 30% more EUs than Sandy Bridge, in order to offer up to 60% faster performance that current Core CPUs according to Intel.

I'll just add Anandtech's Ivy Bridge article for good measure: http://www.anandtech.com/show/4830/inte ... re-exposed

I'd be nuts about Ivy Bridge, but as long as it has that stupid on-die GPU (which is only 60% faster than the current one on Sandy Bridge, compared to AMD's fusion GPU being 300+% faster), I refuse to buy the GPU version of Ivy Bridge. That is, unless Windows 8 can use the on-die GPU for low-power 2D/3D functions like Aero while completely powering down the video card GPU in order to save electricity.

You already can do that with z68 and Lucid Virtu. I don't use that though, I find the integrated gpu is quite handy for controlling an extra monitor with no performance hit at all on my main GPU's. The integrated is pretty decent.

Hmm, this HyperFormance by Lucid is interesting..
"Lucid's 'smarter vsync' could revolutionize game performance
It's called HyperFormance, unfortunately"
see http://techreport.com/articles.x/21682

This would be awesome tech for the APU's IGP if it works well.
