Official Release Date and Ivy Bridge vs Sandy Bridge Benchmarks Revealed

Official Intel Ivy Bridge processor slides got leaked

Recently we heard many rumors that Intel Ivy Bridge processor has been pushed towards second quarter of 2012, but now this time it’s official information from Intel Confidential roadmap slides that Ivy Bridge release has been pushed towards earlier Q2 2012. It’s not uncommon for Intel confidential slides to get leaked, because earlier we had seen Sandy Bridge-E’s official Intel benchmark and roadmap slides, which is found to be true upon release. So this time too we can rely on these leaked slides about the model specifications, benchmarks and release date information of Intel Ivy Bridge processor.

Intel Ivy Bridge Release Date Info

In the earliest start of the second quarter of 2012, 18 models of Intel Ivy Bridge processors will appear, which are located primarily in the high end desktop segment, because 17 of these CPUs are based on four cores. In the later part of second quarter at least 5 dual-core variants in the Core i3 family will be released. Pentium dual-core based Ivy Bridge processors are scheduled for release in the Q3 of 2012. As always, it is not easy for the layman to understand the jumble of numbers and letters, so lets see it after the Ivy Bridge Processor’s Model sheet.

The standard models are clearly structured, they have a four-digit numbering in the 3000 series, with features such as Hyper-Threading and more L3 cache memory. Core i7-3700 series is separated from Core i5-3500 series and the following. Now letters have the game to play and it is more complicated too.

  • K models feature an unlocked multiplier
  • S versions refers to the first low-power batch with a TDP of 65W instead of 77W.
  • T versions are again trimmed further in the direction of energy efficiency, that is why they have a TDP of 45W or 35W

Product Comparison of Ivy Bridge vs Sandy Bridge

However, the graphics unit too affects the designation of processors, for example, Core i5-3475S has 5 spots higher than the Core i5-3470 which means faster graphics unit, S denotes a low-power version. This approach is already well known on the current Sandy Bridge processors itself. Current Core i5-2390T follows the Core i5-3470T, which includes turbo-function and AES support, but comes in dual-core versions, with a TDP of 35W.

Intel Ivy Bridge vs Sandy Bridge Benchmarks

Now, coming to benchmark slides, Intel has made comparison of Ivy Bridge vs Sandy Bridge processors, some in terms of clock speed and some in terms of TDP. At last, the new 65-watt model points clearly, that for the same TDP the clock is at 300 to 400 MHz over its predecessor. We already know Ivy Bridge is manufactured on same Sandy Bridge architecture with some tweaks but in 22nm manufacturing process and Tri-Gate technology.

Improvements in Ivy Bridge Processor

Intel has not only focused on adding pure processing power but also on upgrading graphics. Compared with the basic HD 2000 graphics solution that is currently installed in the “Sandy Bridge”, Ivy Bridge comes with HD 4000, which is up to 3 times faster. This is achieved by increasing the execution Units (EU) and other optimizations.
