    10W to 13W, with a twist

    From Fudzilla today.

    Earlier this week it emerged that Intel is working on a series of power efficient Ivy Bridge chips, with TDP’s well south of 17W. Now the first specs are out and we are looking at five dual-core parts, including a single Core i3, two Core i5 parts, a Core i7 chip and even a single Pentium.

    Although there was talk of 10W and 13W parts, it turns out only the Pentium 2129Y fits the 10W envelope. It’s a 1.1GHz dual-core, sans Hyperthreading and Turbo. It has 2MB of cache and an 850MHz GPU. The Core i3-3229Y also lacks Turbo, but it’s clocked at 1.4 and has four threads. It’s got a nominal TDP of 13W, HD 4000 graphics and 3MB of L3 cache.

    Moving on Core i5 parts, Intel will offer the Core i5 3339Y and 3439Y, both stock clocked at 1.5GHz, with 3MB of cache and 13W TDP. However, the 3339Y will go up to 2GHz on Turbo, while the 3439Y can hit 2.3GHz. Pretty impressive for a 13W part, but the Core i7 3689Y takes it one step further. It’s clocked at 1.5GHz, but on Turbo it can run at 2.6GHz. It has 4MB of cache, and like the other parts, it also features HD 4000 graphics clocked at up to 850MHz.

    However, here’s a twist. All five chips support cTDP Down mode, that lets manufacturers limit the TDP to just 10 watts. Furthermore, they can all be made to fit an even lower thermal envelope – just #$%$ Of course, bringing 13W parts down to just 7W will degrade performance, but at least it’s possible.

    The new frugal Ivy parts should appear in Q1 2013.

    • ' bringing 13W parts down to just 7W will degrade performance, but at least it’s possible.'

      The performance at 10w will be the same performance at 7W, the only difference is that the 7W variants will need a better cooling solution to reduce the max junction temperature from 105c to 80c.

      Also note these are just harvested Ivy Bridge dies still on the high performance 22nm process, these wattages could go even lower with Intel's upcoming 22nm SoC LP process if they needed to but they won't need to as 22nm Haswell and 14nm Broadwell are following on 6-18 month cadences to still compete against the same A15/A6/S4 ARM processors only just on 28/20nm .

      The lowly 1.1 GHz Pentium 2129Y will be the cheapest lowest power Ivy Bridge variant yet still have too much processing power for ARM's greatest processors in most meaningful applications, this is a serious competition only in the silly minds of some dumbo ANALysts, it will be a turkey shoot in reality as each new year's wave of Tick-Tock processors take aim and take out these brash ARM newcomers as they pop up.

    • FROM ZDNET, SEPTEMBER 2012, ON THE INTEL IDF.

      Intel gave two Haswell demonstrations. In the first, he compared a Haswell-based Ultrabook to a reference system using an Ivy Bridge processor that consumes about the same power. The Haswell system delivered a 2x increase in graphics performance in the same power, he said. The difference in the graphics performance was obvious. This is especially significant because the current 3rd-generation Core processors, or Ivy Bridge, already delivered a significant increase in graphics. Perlmutter joked that this is something people expect from Intel but it is no "small exercise." In the second demonstration, Intel compared a current 17-watt Ivy Bridge systems to a 4th-generation Core processor running at half the power (about 7.8 watts in the demo). The Haswell system delivered the same level of performance, he said.

    • 32-bit Geekbench for a 1.8ghz Ivy Bridge does pretty good against the iPad.

      • Interesting numbers. For comparison, the A15 in the Nexus 10.

        ARM ARMv7 @ 1.70 GHz ,1 processor, 2 cores

        Integer Processor integer performance 1776
        Floating Point Processor floating point performance 3963
        Memory Memory performance 2758
        Stream Memory bandwidth performance 1052

        Although the A15 is only 2 threads, Ivy Bridge kills it on memory bandwidth and Integer performance but not in float. Will be interesting to see what the power consumption of the A15 is in reality.

    • as INTC spends vast amounts of money to reinvent newer chips, the smart money makes money keeping things simple like making good old fashioned potato chips the good old fashioned way.

      only fools like Waldo (an old fool who should know better) buy semiconductor chip stocks as long term investments instead of trading plays.

      Never fear Waldo, social security should still be around to support you in your old age
