AMD has been taking a beating lately; when Intel released its Core 2 microprocessor family it was priced and performed aggressively, too aggressively for AMD to adequately compete with at the time. AMD's marketing even went into remission as reviewers weren't even seeded for speed bumps to the Athlon 64 X2 line, the X2 5000+ and FX-62 were the fastest Socket-AM2 parts AMD sent out for review and they were the first ones we'd ever reviewed as well. Sometimes no PR is good PR, and an article around the launch of the Athlon 64 X2 5200+, 5400+ or 5600+ simply proclaiming that Core 2 is once again on top would only work in Intel's favor.

Quad FX came and went with limited interest from the enthusiast community, but the new platform signified a change in AMD's product lineup. Expensive FX series processors would no longer be simply speed bumps of mainstream CPUs with more cache, they would be reserved for a completely different socket as well and sold in bundles of two for Quad FX platforms. It's almost fitting that the FX line has been relegated to a platform that we didn't recommend as it makes the task of encouraging users to stay away from FX-class processors a little easier. And if having to move to a new socket wasn't reason enough to pick an AM2 processor over its FX counterpart, AMD's latest price cuts should seal the deal:

CPU Clock Speed L2 Cache Price
AMD Athlon 64 X2 6000+ 3.0GHz 1MBx2 $459
AMD Athlon 64 X2 5600+ 2.8GHz 1MBx2 $326
AMD Athlon 64 X2 5400+ 2.8GHz 512KBx2 $267
AMD Athlon 64 X2 5200+ 2.6GHz 1MBx2 $232
AMD Athlon 64 X2 5000+ 2.6GHz 512KBx2 $222
AMD Athlon 64 X2 4800+ 2.5GHz 512KBx2 $217
AMD Athlon 64 X2 4600+ 2.4GHz 512KBx2 $195
AMD Athlon 64 X2 4400+ 2.3GHz 512KBx2 $170
AMD Athlon 64 X2 4200+ 2.2GHz 512KBx2 $159
AMD Athlon 64 X2 4000+ 2.1GHz 512KBx2 $144
AMD Athlon 64 X2 3800+ 2.0GHz 512KBx2 $113
AMD Athlon 64 X2 3600+ 1.9GHz 512KBx2 $102

The most expensive Athlon 64 X2, in fact the one being introduced today, is priced at under $500. Clocked at 3.0GHz with a 1MB L2 cache per core, the Athlon 64 X2 6000+ isn't even the most attractive part of AMD's lineup. Shave 200MHz off the 6000+ and you get the Athlon 64 X2 5600+, priced at $326. Note that the X2 5600+ is simply a FX-62 in disguise, what used to be a $999 processor has been reduced to less than a third of its cost - ain't competition grand?

Of course a price war isn't in AMD's best interest when it comes to making money, but it's the best AMD can do until its new micro-architecture makes its debut later this year. As a reference, below is a table of Intel's Core 2 price list:

CPU Clock Speed L2 Cache Price
Intel Core 2 Extreme X6800 2.93GHz 4MB $999
Intel Core 2 Duo E6700 2.66GHz 4MB $530
Intel Core 2 Duo E6600 2.40GHz 4MB $316
Intel Core 2 Duo E6400 2.13GHz 2MB $224
Intel Core 2 Duo E6300 1.86GHz 2MB $183
Intel Core 2 Duo E4300 1.80GHz 2MB $163

The Core 2 Duo E6700 is $70 more expensive than the X2 6000+ but it is Intel's closest competition to the new AMD processor. The E6600 lines up pretty well with the Athlon 64 X2 5600+ at a price $10 lower, while the E6400 is only $2 away from the X2 5000+. While we know that Intel's Core 2 processors are faster, the question that remains is whether AMD's aggressive pricing changes the value equation at all.

Still 90nm

Despite AMD's recent move to 65nm, the highest clocked cores are still built on a 90nm process; this is usually the case when a new process isn't mature enough to produce adequate yields at higher clock speeds. There's also the fact that higher volume processors run at lower clock speeds so it makes sense for a capacity constrained company like AMD to move high volume parts to 65nm production before the lower demand SKUs.

    The maximum measured 8800GTX power consumption is about 150W. NVidia has mentioned that absolute maximum is 180W. However, since this is a CPU review, it's logical to assume that they stressed only the CPU in "full load" power consumption test. Reply

    wow so 260w load plus 50w for a 8800gtx, thats only 310wts! kinda strange when companies are selling 1kilowatt psus.:/ Reply

    i was gonna ask the exact same question. I wish they'd clarify that in the articles when they talk about power consumption. Is that 263wts under load for the 5600+ JUST for the cpu or the whole system? thanks for any of the writers who can clarify this 100%. Reply
  • JarredWalton - Tuesday, February 20, 2007 - link

    Power reports are always for the entire system. Obviously, lower end GPUs would reduce total power requirements quite a bit, but in maximum load testing the stress is only on the CPU and not the GPU. Thus, the ~50W power difference is going to remain whether you're running an 8800 GTX or an X1300 SE. The latter would simply use probably 40-50W less total power. Reply

    Add in OC'ing and Intel, still, jumps further in the lead. Reply

    But most people don't overclock. Reply

    Many of the readers of this site do though. The C2D is so mind numbingly easy to overclock, it's hard to not do it. Reply
  • Roy2001 - Tuesday, February 20, 2007 - link

    I agree. I never OCed before. But with E6400 it is so easy. I just changed FSB from 266 to 350, I have a 2.8Ghz C2D. No voltage change, no cooling change. That's easy. Reply

    Not to mention 800FSB E4300 parts.
    2.66/333FSB is pretty much a safe bet on most boards.
    Even 2.13 for $150 is nice with board at STOCK FSB!.
    Who needs E6400 then :) (for stock performance).
  • poohbear - Tuesday, February 20, 2007 - link

    well if a 2.4ghz C2D can beat a AMD64 @ 3.0ghz, then calling a C2D @ 3.2ghz (the average overclock from what im reading) the "king" processor is a monumental understatement. It'd rape the 6000+. Reply
