Haswell will have an integrated voltage regulator

Autore: Welcome to Fudzilla

For those who need their volts regulated and integrated

Chipzilla’s secret weapon to push its Haswell Chip is an internal voltage regulator which it thinks will cut power consumption.

According to Xbit labs Haswell will not only improve performance and feature some tricks to lower power consumption, but will use a VRM as a secret weapon. This will improve the granularity of power supply to central processing units and thus further cut power consumption without compromising performance.

VRMs usually sit on the mainboards, but recently, multi-phase CPU power supply circuitries were bought in. While these are not bad they cost a bit and take up too much space on mainboards. They also do not improve granularity and performance as well as Intel needs.

Xbit has found evidence that Intel has developed a special programmable chip with 20 power cells. Each power cells is a mini VR with analogue circuits rated for up to 25A electric current and supporting up to 16 phases. Potentially, one 20-cell chip enables 320 power phases per CPU, which allows extreme granularity of power supply. Apparenly Intel will install the integrated voltage regulator (IVR) chip, which will be made using 22nm process technology onto the same substrate with Haswell microprocessors.

Ultimately Chipzilla will build an IVR into microprocessor to further improve granularity of power supply. This will probably appear in Broadwell chips for notebooks, but also for various system-on-chip solutions for smartphones and tablets.

  1. We look forward to receiving a trial order. this would enable you to see for yourselves the high quality of materials and finish put into this model and give you the opportunity to test its efficiency. Grazie!!!

    grazie mille!

  3. Well, I say the ‘The After Eight Face Climb Challenge’, but it doesn’t have a name and I just made that up.

    Ok, so it’s a simple game. For the game, you need two things:

    1. An After Eight
    2. A face

    Step 1

    Place the After Eight on your forehead.

    Step 2

    Moving your head and face, attempt to deliver the After Eight in to your mouth. Nothing must touch the After Eight and you must move it only using the power of your face.

    The attempt will then looking something like this…

    Alcohol consumption may provide added comedy effect.

    Second attempt and I got it in ;)

  4. So here are the facts … I wanna buy a 8600GTS to replace my 8500GT …. and I have a 300W Liteon power supply… I want to give it a shot ..wouldn’t the PSU , in the worst case(though I’m not so sure of that ) burn only if I start overclocking the GPU? …. this is my PSU :Lite-On PS-5301-08HF , I think it’s pretty strong since the rest of my pc is strong ( Quad Core 2.4GHZ , 2 GB Ram ddr2, plus the 8500GT) donno what do you guys think ?

  5. Ciao a tutti volevo sapere se qualcuno di voi ha provato o sa come sono gl occhiali lcd per i miei computer. Io volevo prenderli ma non so alcune cose:
    1) fanno venire mal di testa?
    2) vedo i pixel grossi stile super mario bros?
    3) funzionano bene?
