Ivy Bridge is Intel's next-gen processor that is being manufactured now and is due to land in laptops by the first quarter of next year. It will have more powerful graphics silicon than the current Sandy Bridge chip and offer improved power saving features to boost battery life.

But those marquee features have overshadowed one technology that probably directly affects more PC users: USB. Intel elected not to update USB 2.0 [USB 3.0] in its silicon for 10 years, leaving many data-intensive devices like high-end digital cameras, video cameras, and external hard drives stuck with USB 2.0's relatively pokey connection speeds.

The other hidden gem in Ivy Bridge is DirectX 11, a multimedia and game acceleration technology that Advanced Micro Devices and Nvidia have already been supporting.

The upshot is that Intel will be able support some higher-end gaming and multimedia features that its chips have been incapable of to date. This might include, for example, advanced lighting techniques to enhance the mood of a scene in a game or enhanced shadow effects.

I talk about the intel next generation architecture Ivy Bridge that is based on 22 nn and what these new Ivy bridge based chip that is scheduled to launch in mid 2012 and what improvements they offer over the current sandy bridge based processors.

Ivy Bridge is not just a shrink of Sandy Bridge from 32nm to 22nm ...



Intel's next-generation Ivy Bridge chips will include a host of improvements, including integrated graphics that the company claims will narrow the lead now held by AMD's Fusion APUs.

"I expect that that gap, from everything that I've seen, is closing fast," Intel's director of graphics architecture Tom Piazza told an Ivy Bridge confab on Tuesday at the Intel Developer Forum (IDF), when he was asked if Intel was closing the performance gap with its competition – presumably AMD.

Such a significant redesign is unusual in Intel's tick-tock chip-release cadence, in which a tick in a process shrink – say, from 32nm to 22nm – and a tock is a new architecture. During his IDF keynote on Wednesday, Intel's PC client honcho Mooly Eden referred to Ivy Bridge as a tick-plus – a scaled-down version of Sandy Bridge, but with its own architectural improvements.

Intel to launch 22nm Ivy Bridge processors on April 8


Intel is reportedly preparing to launch the upcoming 22nm Ivy Bridge series of processors on or around April 8. The company is expected to release a total of 25 Ivy Bridge chips during this time frame.

The chips are expected to offer a 20 percent overall performance boost over comparable Sandy Bridge CPUs on the processing side. A reworked internal GPU will produce 30 to 60 percent better overall graphics performance with DirectX 11 and OpenCL 1.1 support.

Intel confirms Ivy Bridge processor delay: Manufacturing difficulties blamed



Intel has confirmed that the delivery of its new Ivy Bridge processor which will power the next generation of Ultrabooks has been delayed.

We had already heard rumblings that shipments of the new chip could be knocked back, but now it has been confirmed by Intel's Sean Maloney.

The Ivy Bridge chips were expected as early as April, but when asked for a new release date by the Financial Times, Maloney said, "I think maybe it's June now."

Maloney suggested the delay was due to the upgraded manufacturing process used to produce the 22nm process chips (compared to the 32nm process Sandy Bridge chips).

Intel's most power-frugal Ivy Bridge processors should be fast enough to satisfy the vast majority of users who are upgrading from a Core 2 Duo-based laptop or even more recent Sandy Bridge processors. Benchmarks show significant gains for Ivy Bridge over analogous Sandy Bridge silicon.

So, without further ado, here's a rundown of Intel's most power-efficient Ivy Bridge processors coming to a laptop near you--via VR-Zone:

  • Core i5-3427U: at 17W, it runs at 1.8GHz. But it can operate at as low as 14W (at lower speed) and as high as 25W. At 25W it can operate up to 2.3GHz (sans "turbo boost," which dynamically throttles the processor speed up or down).

  • Core i7-3667U: at 17W, it runs at 2GHz and at speeds of 2.5GHz at 25W. And note that these speeds can be programmed by PC makers in some cases.

  • Core i3-3217U: This power-efficient Core i3 is rated a 1.8GHz model with no option to increase the wattage--i.e., the power envelope--for higher speeds. At lower speeds its power envelope is 14W. This Core i3 also has slightly slower graphics compared with the above models, topping out at 1,050MHz rather than 1,150MHz. That said, it does support DDR3 1,600MHz memory and has 3MB of cache memory. And note that all Core i3 processors do not offer turbo boost.

  • Core i5-3317U: This chip is rated at 1.7GHz, with no option for higher stock speeds. But the power envelope can be ratcheted lower. There is turbo boost support up to 2.4GHz for both cores and 2.6GHz for a single core. The graphics chip "clock" (speed) is unlocked and can be overclocked--though it's unclear if laptop makers will add support for this.

  • Core i7-3517U: This is a 1.9GHz part that supports the higher 25W power envelope and concomitantly an increased clock speed of up to 2.4GHz. Turbo mode goes up to 2.8GHz for two cores and 3GHz on a single core. This has 4MB of cache memory.



Note that Ivy Bridge chips include both the central processing unit (CPU) and graphics processing unit (GPU) on the same piece of silicon. So, for example, Ivy Bridge (and Sandy Bridge) offers significant power-efficiency improvements compared with an older Intel Core 2 Duo chip with a power envelope of 17 watts because those older chips integrated only the CPU. The GPU was separate.

Intel Ivy Bridge Launch Confirmed: Chips Available For Purchase April 29th


Intel's Ivy Bridge processors have seen a couple delays so far, but the launch date of April 29th has been confirmed with chips available for purchase, according to CPU World. April 8th of course will be the date Intel announces the Z77, Z75, H77 and B75 chipsets, which we reported on back in February.



The rest of the Core i5 lineup and Core i5 dual-core mobile processors will arrive June 3rd. The below chart showcases all chips that should be introduced on that date.

Intel Ivy Bridge Processors To Launch March 23 2012


Intel divides their desktop processors into two segments - the standard voltage processors with a TDP of 77 W and lower-voltage processors with a TDP of 65 W (S-parts) or 35-45 W (T-parts). K-parts are enthusiast-class processors with unlocked multipliers.

The Intel Core i7-3700 series will be the only one that supports the Intel Hyper-Threading Technology, allowing them to simultaneously process up to 8 threads. The Core i7-3700 series also features 8 MB of L3 cache, while the lower SKUs only have 6 MB.

You will notice that there are some oddities. The Intel Core i7-3770K breaks away from "standard conventions" to feature a slight 100 MHz increase in the base clock speed over the non-K version. Both Core i7-3770K and Core i7-3770 will have the same Turbo Boost speed of 3.9 GHz though.

Ivy Bridge CPU Torndown, Photographed, Tri-Gates Revealed


According to TechInsights, the 3.3 GHz Core i5-3550 was packaged in Malaysia and has a die size of 170 mm2, which is down from 208 mm2 for a comparable Sandy Bridge processor. The company analyzed the processor using electron microscopy as well as "x-ray techniques" and spreading resistance profiling and said it discovered 90 nm gate pitches in the embedded SRAM, but also 22 nm gate lengths in the logic areas.

A published picture confirms Intel's 22 nm tri-gate 3D transistors.
