Intel discontinues Core i5 and i7 Ivy Bridge CPUs
Jun 04, 2014: Earlier this week Intel published a few Product Change Notification (PCN) documents, detailing discontinuation of large number of Core i5 and i7 desktop microprocessors. The list includes all Core i7-3xxx models, specifically the i7-3770K, i7-3770S, i7-3770T and boxed i7-3770. Retired Core i5 models include the i5-3330, i5-3330S, i5-3340, i5-3340S, i5-3470, i5-3470S, i5-3470T, i5-3475S, i5-3550, i5-3570, i5-3570K, i5-3570S and i5-3570T.

Preliminary benchmarks of Intel Core i7-4770K CPU surface
Mar 20, 2013: Earlier this week Tom's Hardware posted preliminary benchmarks of Intel Core i7-4770K microprocessor, comparing it with the top Ivy Bridge and Sandy Bridge models. As you may know, most Haswell SKUs have the same specifications as their Ivy Bridge predecessors, and the i7-4770K is not an exception. The microprocessor has the same number of cores, size of caches, CPU and GPU base frequencies, and memory support as the 3770K.

Intel Ivy Bridge processors released today
Apr 29, 2012: Last Monday Intel announced Ivy Bridge microprocessors, and disclosed initial lineup for desktop and mobile markets. The same day the announcement was followed by numerous reviews and benchmarks, published by hardware news site. Today is another big day: the processors are now officially released, and they are hitting retail. Also today, Intel added new SKUs to official pricelist.

Ivy Bridge Performance and Overclocking Overview
Apr 27, 2012: With the paper launch of Ivy Bridge earlier this week, and products shipping from the end of the week, we have taken a look at a number of reviews to give you an idea of what to expect if you buy an Ivy Bridge system, along with an overview of what to expect if you overclock it. Indications so far are that at the same clock speeds, Ivy Bridge will outperform Sandy Bridge by a few percent, but if you overclock it will get much hotter much quicker.

Intel announces Ivy Bridge desktop and mobile CPUs
Apr 23, 2012: Today Intel announced Ivy Bridge (IVB) microarchitecture, as well as 15 quad-core microprocessors, and 5 wireless chipset options. Initial IVB line-up includes six mobile processors, four desktop Core i7 CPUs with Hyper-Threading, and five Core 5 desktop models without Hyper-Threading. All processors will be available in OEM systems and in retail later this month. Some processor benchmark results are already available on Intel website, and earlier today many hardware news sites posted their own reviews with detailed benchmarks.

Ivy Bridge productions CPUs sold on eBay
Mar 31, 2012: Next Intel micro-architecture, code-named Ivy Bridge, is still a month away, however you can already buy unreleased processors. It's not unusual to see pre-production, or engineering samples of not yet released CPUs sold before they they are announced. In this case, however, we're talking about production processors. Several Ivy Bridge production SKUs, including i5-3570K and i7-3770K, are sold in countries like Russia or China. Two IB models can be also bought on eBay.

Revised Ivy Bridge launch schedule confirmed
Mar 27, 2012: Ivy Bridge launch was delayed twice. First time it slipped from the first to the second quarter 2012, and then it was delayed by another two weeks. Current launch date for desktop Ivy Bridge CPUs is set on April 29, which was confirmed by two different sources, Sweclockers and Donanimhaber. That still left us in the dark in regards to mobile processors, due to rumors that their launch was pushed back until June. After seeing recent desktop and mobile roadmaps we can confirm that both desktop and mobile IB chips will be released at the same time.

Ivy Bridge Benchmarks Surface
Mar 11, 2012: As the release of Ivy Bridge grows closer, there has been much speculation regarding what sort of performance boost we will see over a similar Sandy Bridge processor. Intel gave us an overview of the new 22nm process at last year's Intel Developer Forum, and the information that was released indicated an expected performance boost of approx 10% for Ivy Bridge's CPU core and up to over 100% for the GPU. We have now seen some real benchmarks performed by independent testers.

Ivy Bridge to launch on April 8
Dec 28, 2011: There has been a lot of talk recently about Intel reducing prices of Sandy Bridge CPUs in the run-up to the launch of Ivy Bridge. Digitimes today (December 28 ) published details including pricing and release dates for various Ivy Bridge processors and chipsets. Initial SKUs will be released on or around April 8 2012, with a few more parts following over the following few weeks.

Prices of Ivy Bridge desktop CPUs
Dec 19, 2011: Ivy Bridge micro-architecture, planned for the second quarter 2012, will bring a number of enhancements to CPU and graphics portions of the chip. The CPU cores will feature up to 15%, sometimes even higher performance due to micro-architecture improvements and 100 MHz - 300 MHz higher Turbo Boost frequencies. HD 4000 and HD 2500 graphics will add support for DirectX 11, and it will be considerably faster than current HD 3000 and HD 2000 on-chip graphics. What's more important, better performing Ivy Bridge CPUs will come with 20% lower Thermal Design Power. It's great that upcoming CPUs will run cooler and faster, but at what price? Based on pricing information, that we've seen, desktop Ivy Bridge SKUs will have prices, in most cases identical to Sandy Bridge predecessors.

Early Ivy Bridge Benchmarks Revealed
Dec 14, 2011: On November 29 we published details of Ivy Bridge performance expectations. We can now reveal benchmarks results of an i7-3770K sample that was tested by a user on the chiphell forums. Each test was executed at stock settings, so the results are easily compared to those of an i7-2700K at stock settings.

Ivy Bridge Performance Expectations
Nov 29, 2011: On November 27th, we published the first of 2 articles revealing the Ivy Bridge desktop CPU line-up, with details of Sandy Bridge CPUs that are being directly replaced and their Ivy Bridge counterparts. A user in HWBOT forums leaked latest roadmap slides with very detailed benchmarks, comparing equivalent processors from both generations, and showing how different parts of the new architecture will affect performance.

Ivy Bridge desktop CPU lineup details, part II
Nov 27, 2011: Today we published details of upcoming Ivy Bridge microprocessors, that were leaked by news site. As soon as we published the story, we discovered that more detailed list of Ivy Bridge models was leaked by corescn website.

Ivy Bridge desktop CPU lineup details
Nov 27, 2011: In the second quart 2012, Intel is going to introduce 22nm shrink of Sandy Bridge micro-architecture, codenamed Ivy Bridge. As we previously reported, initial launch will include Core i5 and Core i7 desktop microprocessors, along with Core i7 mobile models. Processor numbers and some details of desktop Core i5s and Core i7s were revealed this week by
