New Xeon CPU Hot and Underpowered 293

Kasracer writes "Web Sites The Register and GamePC received several of the new dual-core processors from Intel, dubbed 'Paxville', and ran a battery of tests on them. What did they find? From the article: 'There's no doubt about it, Intel's dual-core Xeons are their most power hungry Xeons to date ... Even when idling, two dual-core Xeons consume nearly 400W of power at any given time, which is amazingly high, even by Intel's standards ... their new dual-core chips (while powerful in their own right) simply are bested across the board by AMD's dual-core Opteron processors. Even worse, the Opterons typically perform much better while running at slower clock speeds and only having half the amount of on-die L2 cache to utilize.'"

    The situation (Intel's, not necessarily the difference) should change RSN when Intel's 65nm process comes online. Looking at the huge lead AMD has right now, I don't see how Intel can beat them in both power and performance anytime soon unless they're willing to add a few hundred more pins to their sockets to accomodate on-die memory controller(s). I doubt Intel will do that. I also doubt they'll come back a bit from the 150W/CPU these Paxville chips crank out, so they'll be using the process headroom for higher clocks and/or larger caches.

    Ultimately an on-die memory controller is the only way to bridge the increasingly large gap between the CPU and RAM. Intel's managed amazingly low latencies to RAM given that they've got an entire extra bus and chip to run through, but they're still ~50% higher than AMD's. The netburst architecture was supposed to be insensitive to RAM latencies but Intel is not keeping up in the bandwidth department either, and it's clear that these CPUs are suffering from a lack of RAM bandwidth (twice the processing power per chip, but no increase in bandwidth).
    • The situation (Intel's, not necessarily the difference) should change RSN when Intel's 65nm process comes online.

      Yeah, but Intel has been depending on technical solutions to cover for their designing flaws. AMD can use yesterday's cheaper fab technology to achieve the same performance through superior design.

      Eventually, Intel won't be able to make a smaller die, and then they'll have to go back to the drawing board and start over to make something that can compete in the marketplace.

        It's less a matter of design flaws as marketing flaws, I think. The P4 sucks in a lot of ways, but it's also very well-done in a lot of ways. The big problem is not so much netburst as it is Intel's inertia. Intel's working on a way to transition their product matrix from netburst on the desktop and in server space to something based on the pentium-M. The faster pentium-Ms beat the fastest P4s hands down in most benchmarks, but there are no good desktop chipsets for it yet, etc. Eventually Intel will release a dual-core P-M-based design, hopefully with an on-die memory controller, and then the Opteron will finally have some real competition.

        Even if Intel eventually hits a process wall, they'll still be able to rest on their huge manufacturing capacity. For the past 5ish years, Intel has been building bigger chips than AMD, mostly in terms of L2 cache. It's not necessarily the best way to improve performance, but it's fairly easy, and leverages Intel's manufacturing strengths. Intel can afford to crank out dies 50-100% larger than an equivalent AMD die, and still make money at it, and still not run out of capacity. The reason Intel has been having shortages of late in the chipset arena is not lack of capacity but bad capacity management. They mis-read the market 3ish months ago and are paying for it now.

        Anyway, here's hoping AMD's 65nm transition goes as smoothly as their 90nm one.
    • AMD developed their CPUs to beat Intel on a clock cycle for clock cycle basis. But isn't it about time both companies show new architectural wonders? Of course, they don't want to quit the market immediately after all the investment to make dual core processors running almost 4 GHz but Intel is reaching the limits of power consumption so what else is coming?

        I'll give you a quick hint: the K8 (I.e. Opterons and Athlon 64 and X2 series) is a freaking marvel of technology. The dual-core variants even more so.

        Intel's dual core chips are just two chips pasted on the same die. Take a look at a proper description of an X2 some time -- there's cache sharing, an inter-cache on-chip hypertransport bus and all that nice shit that Intel just doesn't have. It's not far-fetched to say that at the moment, speaking from a microarchitecture point of view, AMD is a generation ahead of Intel.
    • so they'll be using the process headroom for higher clocks and/or larger caches.
      Haven't we already hit the point of diminishing returns on bigger caches? It's just a simple way to use up transistors. I think I rather have more cores instead.

      In short, decreasing the die size has allowed Intel to reduce power consumption a bit, but it's also increased thermal density to such a degree that they can't clock them as fast as even the current crop of 90nm processors. Why upgrade to these chips?

    (Disclaimer: I haven't read the entire article in depth yet, and I don't know **** about chip design)

    I assume that this chip is basically derived from the Prescott P4, which (in spite of all the hype) has been considered by some commentators to be a dead-end in chip design and a mistake on the part of Intel.

    There are rumours that Intel are now using the Pentium M (ironically, a chip which supposedly owes at least as much to the Pentium III design as to the Pentium 4(*)) as their "reference" design instead of Prescott. Bearing in mind that the Pentium M has been praised for providing performance approaching that of the P4s with *much* smaller power requirements and minimal cooling needed, this wouldn't surprise me. In fact, I've read several articles (including one via /.) promoting the Pentium M as a desktop chip (IIRC passive cooling was possible with a reasonably-sized desktop heatsink).

    (*) And I don't know if that was the previous-gen P4; it's been said by some that Prescott was different enough to warrant the "Pentium 5" name. At any rate, the Pentium M isn't simply a power-efficient Pentium 4.

    I cant see how Intel is going to catch up without a redraw of the whole CPU structure and mem controller. Simply going for smaller die wont solve the performance problem. I really think Michael Dell was wrong in thinking that 65 nm is going to get Intel in par with AMD. This is really and interesting moment, will dell stick to Intel and deliver less performance than HP/Intel/Sun etc? At some stage they will have to start selling AMD and i suspect it will be a horrific moment for Dell. To date they always state that they use Intel because they are better but really how long can they put that charade up?

      Yeah, it's already started. I'd say about 2 years ago.

      The first wave of it was folks starting to harp about the amount of noise that most PCs make. While the Mini-ITX folks were already using fanless systems to reduce noise in specialized application, I think the fanless iMac gave momentum to the movement. At least, that little acryllic cube was cool enough to generate lots of press about being nearly silent.

      Then there were the folks that started buying laptops instead of desktops due to the noise / form-factor / lifestyle choices. Laptops are easier to hide away, can be setup anywhere in the house on a whim, and laptops used to be pretty quiet.

      Hard drive manufacturers switched over to fluid bearing drives a few years ago. At first, it was a marketing thing that allowed them to differentiate themselves from the pack. Now, I don't think you can find too many drive makers who are still making noisy ball bearing drives.

      Energy costs have also gone up in the past few years. My electricty bill has gone from ~$40/mo up to ~$120/mo and I'm starting to consider whether I really want 4 servers, 3 desktops and a laptop running all the time. (And whether I can pack more storage into fewer watts.) Plus the heat issues that all of those systems cause.

      PCs are also continuing to move further and further out of the office. As you moving into the living room / kitchen, folks start paying closer attention to noise / power / heat issues. And PCs have gotten powerful enough over the years, that they are "fast enough" for a lot of tasks. They're starting to compete against things like VCRs / DVD players / DVR & PVR (devices which are typically dead-quiet, low-power, and low-heat).

      Dell even started selling "quiet" PCs a few years ago (most quiet PCs are also lower energy and lower temperature). Those are nice in an office setting for lowering the ambient noise level (which leads to a less-stressful environment).
