Intel To Make A Greener Microprocessor 229
crem_d_genes writes "According to the San Jose Mercury News, Intel is planning microprocessors that have a reduced amount of lead in them (reportedly 95% lower). It's about time a company started this - good job - and let's hope other tech companies take the hint. While many places in the US have banned the disposal of computer parts, there have been unintended consequences of the eco-friendly laws. Many 'recycled' computers currently get shipped overseas where parts eventually make their ways into the hands of workers who usually 'burn' the parts to get rid of plastic and recover small amounts of valuable metals. In the process they are exposed to the toxic compounds that are released. In other cases, lead makes its way into drinking water."

Now granted, the "need for speed" in recent years has caused the net effect to be higher power consumption, but if consumption were anywhere near the level of older processors, but with the transistor count and switching speed of current processors -- we'd need some very serious heat dissipation.
Right now, speeds are fast enough that raw clock speed isn't as much of a concern for consumers any more. Even I don't feel the need to upgrade at this point, as the gains would be minimal. Any machine you buy new today will be more than sufficiently fast for what most users do, and most of them will play current and near-future games with ease.
So the push is now back to power consumption, just like when all the "Enegery Star Compliant" stuff first started appearing. Notice that most PC companies are making much quiter PCs, giving them smaller and more stylish designs, etc -- rather than having the fastest available CPU, etc. Lower power consumption falls inline with this, especially with making PCs quieter (less power means less required cooling, smaller power supplies, and ultimately smaller and quieter PCs).
It's all a matter of what's going to sell at a given moment. If we required more CPU speed, power consumption be damned. While we don't really need more speed, focus can go to power consumption and efficiency.

AMD fanboys listen up: Yeah, you guys are winning the strongarm race right now. You've got the faster middle-class processor (upper end desktop/lower- to medium-end server) and Intel knows this quite well. They could scale Prescott very quickly up, but so would come heat, and therefore energy prices.
Now, lets look at other moves Intel's made lately. They've announced they're going to a PR-rating for selling processors. What sense does this make if they're just going to ramp up their processors even faster clockwise? Why do they need to compare anything except clocks? Well, because AMD is wiping the floor with them, that's why.
90nm technology has also been undergoing perfection with Prescott, meaning lower voltages, higher yields, less wasted silicion on the wafer.
Both of these things bring us to the sucecssor to Banias, Dothan. Extremely large cache, 90nm technology, extremely fast CPU. Not only will this be one of the most (energy effecient/clock effecient) chips ever made, it most likely will be the next desktop processor. But, here's the kicker, for them to be able to do this, they need to take a short pause from ramping up their current technology's speed, and moving Dothan over to a bigger mass production line. This is why we find Intel pretty silent right now, and most likely the same with AMD (anticipation; AMD's a very reactionary company).
So, I'm very sure that this is one of the top priorities sitting on the desks of Intel Engineers, I applaud them for taking every step towards a cleaner environment while making my newest tech gadgets.

To clarify (and make sure I'm understanding correctly), Intel's "more MHz/GHz is better" marketing approach is presenting a problem to even themselves, much like it did for AMD a couple of years ago. Now that Intel is making more effecient (work done per-clock) processors, like AMD has been doing, simply comparing MHz among even just Intel processors is no longer a good performance measure, and might even make their new line appear slower (again, when comparing only clock-speed numbers).
It sounds like they're taking a step back from the P4 design, which were slower clock for clock than even their older (PIII) processors, but capable of higher clock speeds; so at the time the MHz myth worked to their advantage, where now it is no longer to their advantage.
That, and the market (in my opinion) isn't as speed-hungry as it was just a year ago. A quieter, smaller, more energy-efficient PC design is more likely to make the average user upgrade than a faster, beefier PC.

There are alternatives to Pb, but normally they require higher temperatures for soldering, which have an impact on the package thermal characteristics and material, which in turn may have some influence on the performance of the chip itself, so these changes have to be handled carefully.
At the moment the US does not have a deadline for phasing out Pb (I think they refused to sign up?) but the EU does, so if Intel wants to sell chips in the EU, or Japan, they have to provide Pb free alternatives.
One person mentioned that this is a small percentage compared to the rest of the Pb in a PC - which comes from the solder mainly, but what you should remember is that the EU directive applies to ALL Pb products, and therefore all circuit boards will be Pb free too.

Eutectic alloys have a lower melting point than any of it's components. That's exactly the reason why lead is added to tin, in soldering alloys.
Another very efficient dopant is silver - it decreases considerably the melting point. Unfortunately, it's expensive.
Tin is basicly innocuous, while lead is toxic. The problem with lead is that it causes a chronic poisoning called saturnism, where your brain suffers considerable damage - in fact, largely unrecoverable.
I should add here that there are historians that think one reason for the fall of the roman empire lies in the use of lead cups for drinking wine. These lead cups were quite popular in the roman army, and it's not inconceivable that this might have decreased the soldier's mental and physical abilities.
The problem with the lead-free soldering technologies is exactly the higher melting temperature of pure tin compared to the eutectic alloys. Reflow and other technologies have to be fine-tuned for higher temperatures, and the risk of damaging some of the components is significantly higher.
