Two New AMD Mobile Chips Launched
to_kallon writes "Advanced Micro Devices (AMD) has unleashed two new mobile microprocessors today. One processor belongs to the company's 64-bit Mobile Athlon64 line while the other one comes from the 32-bit Athlon XP-M product line. According to CNET News: 'Like other Athlon 64 chips, and Intel's Prescott, the new Athlon 64 3400+ will block many security threats automatically in conjunction with Windows XP Service Pack 2. The delayed SP2 is slated to come out in August. The Athlon 64 3400+ will also run a 64-bit version of Windows, due now at the end of the year.It runs at 2.2GHz and comes with 1MB of cache. Gamer-PC maker Alienware will insert the chip in a notebook later in the month. Meanwhile, the Athlon XP-M 2200+ comes from the company's older line of chips. It runs at 1.6GHz and is built around an older processor core and comes with a 512KB cache. Averatec, a small computer manufacturer, has put the chip into a notebook that can convert into a tablet PC, marking the first time AMD's chips have been used in a tablet'."
AMD has also recently released a new multiprocessor motherboard configuration for its low-end processors. Machines based on this technology will specialize in playing 80's MP3's.
They're calling it the Duron-Duron.

With all these new advances in processor and video-card technology, when are we going to see some advances towards cheaper, and quieter cooling solutions? These devices keep getting hotter and hotter!
In order to keep my gaming computer cool I have something like 7 or 8 fans in there, and the box sounds like a jet-engine taking off... I've looked into water-cooling but virtually every water-cooling setup costs upwards of $200. Is it really *that* expensive for the equipment? What other alternatives are out there?
And with a notebook... isn't heat going to soon be a real serious issue with laptops?
my sig was dubm so i took it out.

Prior to this, they were either injected or used in suppository form.

It doesn't, it's the other way around - this CPU has a feature (NX bit) that WinXP will be aware of as of SP2.
Don't worry the proc has no idea what OS is running. Its just that it supports a noexec instruction which lets you mark areas of memory as data vs. code, this makes the buffer overflow attact a little harder because the chip won't do instructions in an area that is flagged data(where the array you are exploiting would be). SP2 will give the windows OS the ability to support performing that instruction in some instances and therfore enchance security. I have already heard noises of implementing this in Linux and *BSD. Its complex from a software stand point to make really effective use of as you have to be able to predict the future to some degree but its probably a good security tool noone the less and could be extreemly benificial in many cases.
The Hammer based chips run cooler than their older AthlonXP brothers. They also add cool-n-quiet for power management. My Athlon 64 laptop (with a DTR chip) rarely gets very warm and the lower power portable Athlon 64 chips are extremely cool (nearly in the G3 - G4 power range which is really impressive for an x86 chip). The P4 based laptops, however, can literally burn you. If you go the Intel route, the Centrino platform is excellent and one of the best chips ever by Intel.
[RIAA] says its concern is artists. That's true, in just the sense that a cattle rancher is concerned about its cattle.
Intel has 'unleashed' new low voltage and 'ultra low voltage' Centrinos and Celerons.
You know you've been IMing too long when you almost say 'lol' out loud to a non-geeky friend...
The processor comes with a "no exec" op code that an operating system can use to enhance security. OpenBSD or Linux could use this just as readily as XP. As a matter of fact OBSD already does iirc and MS isn't doing anything truely original on this platform (yes, I'm aware other processors and OSes have offered this for years.)

But it doesn't prevent the overflow, just the injection. This leaves your program free to (behave poorly|crash).
The World Wide Web is dying. Soon, we shall have only the Internet.
You can get Virus Protection without an AMD processor here.
Perhaps you would care to enlighten the more elite vendors out there then. And by your analogy, Intel is the largest retailer, making it worse than AMD.
Dream the day dream.
Keep your eyes to the sky.
I'm getting ready to build a new PC and I've decided on the Athlon64 (it was such a difficult decision... not.). It looks like the mobile chips are basically identical to their desktop brethren except that they don't put out as much heat nor do they have integrated heat spreaders. I really like the fact that they put out less power, perform identically (I think), and only cost a few dollars more.
Does anyone know if you can take a mobile A64 and just plop it in a desktop motherboard (for regular A64s) and have it just work? Or does the BIOS have to be aware of the fact that it's a mobile proc? Will the heatsinks designed for the desktop versions work with a mobile version? Does an A64 really require a 400W+ power supply as many sites suggest?
NX. Sections of memory that are marked as containing data ONLY, which cannot be made to execute. If you try to execute this memory, an exception is raised.
Helps you with things like buffer overflows that are such a PITA today because of sloppy code.
They are theoretically compatible, but it depends on whether the motherboard in question supports them. The Asus K8N-E Deluxe looks like it does a good job of that, though information is scarce as it's pretty new. As for heatsinks, they aren't inherently compatible, but the Thermalright SLK-948U is one that is.
And a true mobile will work just as well as a DTR, and have even better thermals (in the case of the 35W mobile 2700+/2800+, magnitudes better).
Work is punishment for failing to procrastinate effectively.
against Intel now in the laptop market as well. AMD has steadily been gaining against Intel is the desktop market, but I really think that the laptop market is the place to be(in terms of cash of course) Also nice that they are attacking at both ends, the performance end and the budget end.
With the advent of wi-fi, I see a lot more people ditching desktops all together and using a laptop as their only machine. Why not? Laptops easily have enough power to check email, browse, use an office suit all at the same time. And you can take them anywhere. And with a low end laptop only a few hundred more than a lowend desktop, there really isn't the financial motivation to get a desktop anymore.
Desktops aren't dying, but the real growth(at least in terms of the mature world economies) will probably be in laptops in the coming years.
