Intel Announces New Chips, Chipsets 113

Posted by michael from the intelfanboydotcom? dept.
Saud Hakim writes "Intel showed a prototype of an IEEE 802.11a wireless LAN transceiver created by using a 90-nm CMOS (Complementary Metal-Oxide Semiconductor) fabrication. The chip can switch between different networks and frequencies; it is capable of tuning and tweaking itself. It is also capable of detecting what kinds of wireless networks are available nearby and shifting to the frequency that is most appropriate." Reader serox sends more: "Intel has two big news releases today and IntelFanboy has it covered. First up is the new Xeon processors have been released with a list of improvements. Second, Intel has revealed two significant milestones in the development of extreme-ultraviolet (EUV) lithography that will help lead to developing the next generation chip technology."

    It's new Intel server platforms based on the Xeon that have been release; not new Xeons.

    That being said, this really bulks up the low-intermediate end of the Intel enterprise offering.

    But the leakage current problems have been increasing with process shrinks (not just at Intel, but also at IBM and AMD). So they can use even smaller lithography. Great. Will the leakage current and associated heat suck even worse than Prescott?
    • According to the article, they can use less power, due to the feature shrinkage.

      I won't pretend to understand the relationship of power and leakage wrt feature size, though.
      • My very basic understanding of the relationship is this, it takes less power to cause a smaller semiconductor to switch states, however as you move wires closer together you start to have capacitive leakage and inductive effects from the wires. Up until a few years ago, you the former was signficantly larger than the latter, but in recent years they have become more equal in magnitude of effect.

    • I read somewhere today that Intel engineers have developed a new compound to use for the insulating layer on the gates, to replace SiO2. This was said to reduce the leakage currents and allow finer lithograph. IIRC the article said they were planning to start using it for 55 nm lithography.
    • > But the leakage current problems have been increasing with __process shrinks__ [my emphasis] (not just at Intel, but also at IBM and AMD).

      Not really true. Leakage current doesn't increase significantly with just a process shrink; rather, it tends to be associated with process shrinks because one of the main reasons for a process shrink is to rev the clock rate up. In this case there is little reason to rev the clock rate on an 802.11a/b/g chip that is processing signals at pre-defined frequencies.
      • Thanks for the interesting responses, folks. I feel I've learned a lot. Perhaps I didn't RTFA well enough, but I was under the impression that these were two separate news items: one about wifi chipsets, and another about a new lithography technique that Intel would be using ubiquitously, including for future CPUs.

        I definitely agree about the power savings from the process shrinks (thanks for the correction!); we saw those in the Coppermine->Tualatin shrinks and the Willamette->Northwood shrinks,

      • That's actually a funny story, with more point than you realize. A while ago, a number of groups spent a lot of money on x-ray lithography, without any commercial success. Because of this x-ray lithography has a bad reputation. So, to distance the technique from x-ray lithography, and to more closely align it with the very successful optical lithography, they changed the name to EUV lithography from projection x-ray lithography.

          • Yes, 13.4 nm (~100 eV) is far from hard x rays (> 30 KeV), but who said anything about hard x rays? X-ray lithography was generally done with wavelengths near 1 nm, so it's hard to say if 13.4 nm is closer to 1 nm or 193 nm. All three techniques are very different.

            In any case, look some of the first work done on the technique by Bell Labs and others in the late 80's, early 90's. Those papers refer to the technique as soft x-ray projection lithography.

      Not really. 802.11a operates in the 5 GHz band, and can thus coexist with 802.11b without suffering degradation, unlike 802.11g which does degrade when .11b devices are present -- if nothing else because the .11b devices hog the channel for 5 times as long.

      Thus, heavy-use WLANs like corporate installations are frequently A+G, and a lot of current wlan client chips are also A+G.

      In the current wlan market, 802.11a is the premium solution; unfortunately both in terms of cost and performance.

    • Just FYI, the operating frequency of the radio has *NOTHING* to do with its speed. At whatever the frequency the radio operates on, it uses a fixed amount of frequency width (which is on the order of 30 MHz not GigaHz). So, if I am on 10 GHz, it means that I am allocating frequencies between (10GHz-15MHz) and (10GHz+15MHz). It doesnt mean that I have a CPU running at 10 GHz. Operating speed of these radios are based on reception power which is generally inversely (and exponentially) proportional with the di

        Harvard architecture [wikipedia.org] refers to seperating instruction and data memories, unlike Von Neuman architectures you find most places. Harvard architectures are still popular in many microcontroller families, though.

        Whether parts are certified for static operation (e.g. clock frequency down to 0Hz) is a completely different matter.

        • That has nothing to do with harvard architecture, and your 68040 wasn't a harvard arch.

          That is not 100% accurate. Actually it is common to designate CPUs as a harvard architecture when they use separate data and code caches. For example it is impossible on the 68040 to modify code that resides in the code cache.
          • This is semantic. Harvard architecture implies seperate paths for data and instructions. The path into the CPU for the instructions is the same as the path into the CPU for data.

            On the 68040, yes, there is a separate I-cache that isn't coherent with memory writes. But it is quite possible to use instructions that operate on data memory to modify code-- as long as you're sure to invalidate the i-cache before the code runs.
