Intel Corp.'s attempts to lower power consumption of its chips aimed at ultrabooks and eventually at media tablets and smartphones inevitably bring fruits to desktop personal computers as well. Based on unofficial information, the company's next-generation Ivy Bridge microprocessor will have substantially lower thermal design power compared to the existing desktop chips.

Initially believed to be an evolutionary step from the Core i-series "Sandy Bridge" microprocessors, the Core i-series "Ivy Bridge" central processing units (CPUs) will be much more than just a "tick" in Intel's roadmap. Apparently, the chips, in addition to all major innovations that Intel installed into it, will have numerous power management improvements that will reduce nominal thermal design power of high-performance Ivy Bridge desktop CPUs to 77W, according to a slide that resembles those from Intel's presentations published by ChipHell web-site.

For several years Intel's performance mainstream and performance microprocessors had TDP of around 95W. For example, Intel's current top-of-the-range "non extreme" quad-core Core i7-2600K microprocessor with unlocked multiplier has 95W thermal design power, just like its lower-end brethren. By contrast, the future Intel Core i7-3000K "Ivy Bridge" chips will have 77W default thermal design power, which means lower overall power consumption as well as quieter operation of the whole PC system.

In addition to high-performance Core i7-series "Ivy Bridge" chips with 77W TDP, Intel will introduce Core i5 and Core i3 "Ivy Bridge" quad-core microprocessors with 65W and 45W thermal design power as well as dual-core processors with 55W and 35W thermal envelopes. Previously, Intel recommended to use notebook-oriented 35W processors for low-power performance desktops.

Reduced power consumption does not mean lower overclockability or lower Turbo Boost improvements. Thanks to configurable thermal design power  feature, system makers and end-users will be able to increase or reduce TDP in order to allow chips to more significantly increase clock-speeds in Turbo Boost mode or disable automatic overclocking in order to squeeze the chips into smaller form-factors.

Ivy Bridge will generally inherit Sandy Bridge micro-architecture and will sport a rather significant number of improvements. Firstly, it will have certain improvements that will boost its performance in general applications by around 20% compared to Core i "Sandy Bridge" chips (e.g., enhanced AVX acceleration). Secondly, the forthcoming chip will have a new graphics core with DirectX 11 and OpenCL 1.1 support, 30% higher performance compared to the predecessor as well as new video processor and display controllers. Thirdly, Ivy Bridge will feature PCI Express 3.0 x16 interconnection as well as PCIe 2.0 x4 controller. In fourth, the processor will support a number of power management innovations. The CPU is made using 22nm process technology.

Intel will release its code-named Ivy Bridge central processing units for desktops in March or April, 2012.

So as Intel is not being pressed by competition instead of launching better performing chips, they launch moderately better chips but with lower TDP.

I see PC CPU market slowering in terms of performance thanks to AMD lack of needed products.

I'm all for lower TDP. And it's expected to be faster in addition. How is that bad? I want 100% silent computers!

77W is not a huge sacrifice. Even in the heyday of the Pentium 4, the 2.8GHz Pentium 4, which was (in its time) the standard for mid-high grade CPUs had a TDP of LESS THAN 75W. A 125-130W CPU is absolutely insane, absolutely noisy, and undesirable for most consumers. Even 95W is a little bit high when you consider that's equivalent to 1 and a half lightbulbs.

dudde,if you have tons of money,you think youll have the same will to go to work? That analogy aplies to Intel too. If you think they will work hard to give you better Cpu's now that they have no competition you are wrong man.

tell that to AMD! until they can come up with a better cpu than crapdozer, these bridge chips (SB and IB) will provide sufficient performance.

there's nothing wrong about competition. As long as the participants are competing well. Bottomline is right now, no matter how you sugarcoat it, AMD just can't compete well in the top-tier in terms of performance.

You are thinking about this backwards; no company that sits on their butt will survive very long. Andy Grove (former Intel CEO) believed strongly that only the paranoid survive, and I don't think Intel will be making another "P4" mistake anytime soon.

Besides, Intel has bigger things to think about than AMD. Think big picture beyond just PC/Server CPUs.

But here we are talking about the desktop/server market. If Intel improves on other areas is irrelevant.

AMD is definitely making a Pentium 4 mistake. Still, consider this: over time, P4 chips got better and better, offsetting the inefficiencies of the architecture with raw performance ability. AMD "Dozer" chips will get better and better, they just haven't lived up to their full potential yet due to inadequate firmware. The whole idea behind them makes too much sense to fail, but Intel incorporates so many technologies that AMD lacks, such as the upcoming Tri-gate transistor technology. Nothing AMD can do in just 1 year will give it the ability to stand up to that. AMD should just stick to the entry-level to mid-grade market with its Fusion APUs that can be manufactured cheaply by using well-established technology.

This would be a nice change from the flame throwing Intel chips of the past. I remember one website frying an egg on a PIII CPU and video recording it.

Intel's 77w CPUs are an attempt to mimic AMD's 65w CPUs that they have been selling for a long time. It's a step in the right direction as AMD realized a long time ago. AMD even has A-series APUs running at 65w which is impressive with the GPU combined with the CPU.

I'm still using one of those "flame throwing Intel chips" in a Dell laptop. It called a P4 running at 3.4Mhz. It's great to keep my coffee warm while I'm reading emails :-)

I don't understand some peoples logic on here. Lower TDP, 20% more computing performance and 30% more graphical performance equals a decent amount of performance over Sandy Bridge much like what Sandy Bridge was over Nehalem.

AMD needs help fast. Intel is leaping ahead on every front and ARM is devouring the low end. Unfortunately AMD's resources are so limited they are in real danger of being reduced to irrelevancy as far as CPUs are concerned.

Yeah, the way VIA went. Maybe thats why we saw some kind of RAM has made by AMD. Maybe AMD interested in designing minor chips rather than processors to survive. But I accept. They kinda need help.

I don't think so...

Demand for AMD Opteron, Llano and FX series CPUs exceeds demand.

Yes AMD needs to improve production issues but they have been getting huge system builder gains because they offer good products that end users desire.

AMD has sold over 12 million APUs in the past nine months. Cray bought the first 10,000 Bulldozer based Opterons and has standing orders for more. FX series chips are selling well and Newegg and others are exhausting their inventory quickly.

Does AMD need to improve Zambezi/FX - Yes. That will come with the Piledriver version. Llano is being superceded by Trinity in Q1 of '12 and it's significantly faster than the best selling Llano.

AMD is hiring more experienced management to try and smooth the delivery process. According to many people AMD is "close to going out of Biz". This mantra has been stated by so many armchair experts over the last 40 years, that I just laugh every time I hear it.

BTW, AMD has been selling 65w CPUs for years and now they have 65w APUs and soon will have 35w Trinity APUs and even 17.5w Trinity APUs for those who need extended battery life on a laptop.

Over the years Intel has sold quite a few flame throwing model CPUs so it's good to see them copy AMD with lower power consumption CPU designs.

Bulldozer should do good in their primary target: HPC and server applications.

AMD has 5.5% of the server market, down from 20% a few years ago. Not a great trendline.

Are you still in an outdated life? maybe from 2001/2002???

Selling well?? AMD can't even make enough of these toaster chips! It just makes a false sense of demand! Now that the reviews are out for crapdozer, your so-called demand will plunge!

Regardless of who AMD hires these days, their role will definitely be doing damage control!

Intel too is Selling 65w Processor, Wow copy Amd lower power consumption, so Core2 was from AMD Design? Dont add false assumption without any document

Not in the budget desktop market. Their Fusion APUs are a good idea to make solid money: combine 2 well-established technologies with some minor tweaks (eg. 32nm shrink) to make something that can be cheaply and easily manufactured. At the APU price point, all Intel has is dual core chips with inferior integrated GPUs. That i3 serves only a niche market of people who need Single-threaded performance and little else. It doesn't matter what kind of marketing hype is thrown at us, Hyper-Threading is NOT the same as twice as many cores(or even 1.33 cores). I love Intels high-end chips and notebook chips, but AMD has the mainstream budget market for desktops(though that market is shrinking with the dominance of laptops and mobile devices.)
