Ars Evaluates Core 2 Duo in Latest System Guide

RevDobbs writes "I always take a peek at the Ars Technica System Guides before white-boxing my next PC. Well, today I hit the site and see that they recently published their first post-Core 2 Duo System Guide." From the article: "The new Intel Core 2 Duo processors bring a swift change to the Hot Rod, making the lifespan of Socket AM2 very brief in the Hot Rod. Performance from the Core 2 Duo (aka, Conroe) appears to be excellent in all regards, from pure performance to heat output. Overclocking prospects also look excellent, with an overclocked Core 2 Duo being an amazingly fast chip for the money."

    Intel is doing a lot of things right. This is a common core from laptop to server. Keeping it simple--AMD has a lot to worry about. I wonder about what a giant leap in energy issues would do. For example, greatly reduce power reduction at the transistor level. The whole issue of power usage would go away--and you'd have Intel and AMD racing for performance as they did in the late 1990's. The Conroe is a great processor, but a lot of effort went toward being miserly.

    And I'm still waiting for an architecture change. How about finally retiring the byte as a base logical unit? In return, just use the bit, or whatever word length the machine is.

      Um, the laptop processors were the same as the desktop in the 754 pin category. And in the Socket A they were ALSO compatible with the desktops.

      And the move from K7 -> K8 brought about 90nm SOI which greatly reduced power and heat issues. A similarly clocked K8 would easily run 10-15C cooler than a K7 at idle.

      AMD has plans to move to 65nm and 45nm. I won't say when [cuz that's secret and frankly I don't remember anyways]. They're just not rolling out a completely new core every other month to avoid wasting time supporting really short lived products.

      Conroe seems like a decent design. Until I build a box with one I can't really say. If all the hype is true though it's a good competitor to AMD K8, not a replacement, certainly in a lot of server oriented computing tasks.

      Intel is the first but not always the best. Their move to 90nm for instance led to Prescott processors hotter than the sun. Granted their move to 65nm was a lot smoother, being first isn't always the goal.

      Frankly, even given where I work I'm happy that Intel is turning out good [or at least better] hardware. We all win when technology is getting neatoer.

      I'm reading rumor and news leaks that say more along the lines of Q4/2006 for the 65nm production. The new Opteron socket F CPUs are due out soon and I'm not sure whether they're going to be 90nm or 65nm. And that could slip until 1Q/2007 or later of course. (I confess that I mostly scan the news looking for when AMD's next price cut is going to take place. Because we mostly buy CPUs in the lower half of the Athlon64/Opteron lineup.)

      AMD is always going to be a generation behind on process size. It's the nature of being a smaller company (have to make do with less). So the downside is that AMD is always going to lag 6-24 months behind the process shrink of Intel. On the other hand, they've done very well with 90nm technology. So while the 65nm shrink won't be a magic bullet, it will hopefully at least narrow the gap (in terms of overall performance, power consumption and thermal output).

      It's a good time to be a customer. For either side of the fence. Reasonably priced chips that are multi-core, hardware virtualization (making things easier to run multiple O/S instances), and increased competition between the two sides.

      (We're mostly rolling out AM2 X2 3800+ CPUs in our desktops because it's reasonably priced. If they fire-sale the old 939 X2s, we may pickup a few more of them. Odds are low that we'll upgrade CPUs down the line, but it's a reason to favor AM2 over 939. The Core 2 Duos are still more then we want to pay for a desktop CPU and we don't want to buy end-of-life Pentium D 805/9xx dual-cores. If a low-end Core 2 Duo was $120-$150, I'd consider it for these particular machines.)

    So instead of doing

    movb (%rax),%bl

    movq (%rax),%rbx
    andq $255,%rbx

    With the Core 2 Duo processor, there has been quite a significant leap in energy issues. While the current trend for the past 4 or 5 years has been to beef clock speeds and performance at the expense of power consumption, Intel's major stride has been to drastically increase performance while cutting power consumption in half. If AMD can match this power consumption (Intel's chips currently run at 40W according to their information), then we can concentrate again on having a speed war. The effort that went into being miserly had to be done at some point, and now it's up to AMD to catch up.

    There isn't a decent board for the Conroe that's under $250.
    Either they don't support DDR2800 (anything less is a waste), or they don't have SLI, or they're missing amenities like firewire or decent onboard sound.
    A "budget" Conroe system is difficult to spec since unless you go DDR2800 you aren't going to have much over a DDR400/DDR500-based AMD K8 system (and I'm not talking AM2, but the same logic applies). Memory bandwidth is a bottleneck for performance and usability. Despite Conroe's advances in CPU power, most situations where you wait for the computer are not CPU bound (unless you are heavy into movie/music decoding/compression). An bus-overclocked low power K8 (like the Opteron Denmark) can still beat a Conroe system in memory throughput.
    DDR2800 brings this to parity but then you are not talking about a cheap system anymore; it's everything EXCEPT for the CPU that costs too much.

    Hopefully in the next few months we'll see price drops in DDR2 memory and more competetion in the Core-2 Duo compatible motherboards. This should make them more affordable and help to shake out the gold implementations.

It's not like X2AM2 chips are that much different from X2939 ones...

      I sorta remember that too, so I went and looked. Socket 939 came out in June 2004 (or thereabouts). This could be part of the downside of having a built-in memory controller. Since DDR reached the end of it's reach (PC3200 seeming to be the fastest commonly available) and DDR2 commonly available, they decided to go with a new pin-out so that you couldn't mistakenly mix/match the wrong CPU with the wrong memory. Less confusion for the customer.

      At least, I think that's why the pin-out was changed... (according to the AMD FAQ it was).

      What AMD has said at this time is that the new AM3 chips (which support DDR3) will be compatible with AM2 and AM3 motherboards. So you can put an AM3 chip into an older AM2 motherboard, but not the other way 'round. We'll see if that holds true...

    2. The push to the socket AM2 architecture was to enable DDR2 support for AMD chips. Socket 939 could not support the faster memory that is hitting the market now, such as the DDR2 800Mhz (cheaper) or the brutal DDR2 1066Mhz (save your pennies).

    AMD has stated that the AM2 platform motherboards will be able to support their next generation of chips. So if you are like me and made the plunge, your mobo won't be obsolete for a good long time.
