Re: Editorial : AMD's 2000 Roadmap - The Facts? Whooeeee - editorial is right. That's one of the most spun pieces of writing I've ever seen. Not quite outright lies, but very close to the line. I wonder how much "support" he's been getting from Intel? I think I know why AMD is being careful to limit samples of Duron and Thunderbird, they want to limit the amount of time Intel's Bapco subsidiary has to comb the universe for "benchmarks" that make AMD look bad and Intel look good.

I like this part--AMD's Mustang The third derivative of the Athlon core will be the Mustang, which will be out sometime in Q3/Q4 2000. The Mustang core will offer some tweaks and enhancements over the Thunderbird core, including support for larger on-die L2 cache sizes (~1MB) as well as AMD's PowerNow! technology. AMD has not disclosed any of the other feature enhancements as they are concentrating on the Thunderbird/Duron parts right now. However, closer to the release date of the Mustang, you'll hear more about it. The Mustang will actually be quite a bit more than simply the server/workstation Athlon part; the high end market will simply be one area that the Mustang is geared towards. The Mustang will eventually find itself in every Athlon derived processor after its release, starting off as the core for the Athlon Ultra (High End server/workstation part), but by varying the amount of on-die L2 cache, the Mustang core will find its way in desktop Athlon parts as well as in mobile Athlon solutions. This means that the Thunderbird will be fairly short-lived if it is to be replaced by the Mustang as the core of choice for the Athlon later this year, and it also means that AMD is going to be able to compete with Intel much more seriously than they have in the past in the mobile market with the mobile Mustang. The mobile Mustang, going under the code name Corvette, will feature a smaller L2 cache than the desktop Athlon (Mustang) part and a lower voltage, which makes sense since it will be a mobile part.

ThunderbirdThe Jack of all Trades - AMD's MustangAthlon goes MobileChipset & Motherboard SupportFinal Words anandtech.com Athlon goes Mobile The Corvette will put AMD's PowerNow! technology to good use. You may remember PowerNow! technology from last Comdex when we referred to it as AMD's Gemini technology, which was talked about around the same time as Intel released their first mobile Pentium III processors with Speedstep. AMD really wants to illustrate that their PowerNow! technology is dramatically different from Intel's Speedstep, and it actually is. Intel's Speedstep technology allows a Speedstep enhanced processor to switch clock speeds/voltages when plugged into a wall versus when running off of battery power alone. For example, Intel's mobile Pentium III 650 with Speedstep technology runs at a core voltage of 1.60v when plugged into a wall outlet (i.e. not running off of battery power). When the laptop switches over to battery power, the clock speed drops from 650MHz down to 500MHz while pulling the core voltage down to 1.35v in order to conserve power. AMD's PowerNow! takes this one step further. Instead of simply decreasing the clock speed and the voltage of the CPU when running off of battery power, the PowerNow! technology in combination with the motherboard's BIOS allows for the dynamic adjustment of clock speed/voltage of the CPU during actual program usage. For example, say we have a 600MHz mobile AMD processor equipped with the PowerNow! Technology. Upon launching a program such as MS Word, the processor will most likely operate at close to its full speed, but immediately after the loading process is complete, the CPU will drop to a slower clock speed and lower voltage. During this time, if you decide to start up another application or begin doing some very CPU intensive calculations (ok, maybe not in Word) the PowerNow! technology will increase the CPU's operating frequency in order to compensate. We will see PowerNow! used in AMD based notebooks this summer, but these notebooks will be using K6-2+ or K6-3+ processors, not the Corvette. Milo

Chung - RE: "Editorial : AMD's 2000 Roadmap - The Facts" Yikes! The situation is much worse than I thought. And not only is the Via KX133 chipset incompatible with Thunderbird, only OEMs will get the slotted versions. While this is good in that AMD is going to lower cost sockets faster, this is going to leave many current Athlon owners ticked off because they can't upgrade, unless a slocket card is made AND they are using motherboard based on the AMD 750 chipset. The sad thing is people were actually waiting for the Via KX133 chipset becasuse they thought it would be the better option later down the road. But those people are now left with a dead end platform... And again, AMD is left at Via's peril with the KZ133 chipset. I hope this thing works as planned. I'm surprised at how Anand paints the picture that Thunderbird will be so short lived. I guess it depends on how fast AMD wants the transition to Mustang to be. With so many potential chances for error this year, AMD's ability to execute will be put to the toughest test ever. I just wish it wasn't so dependent on Via.

Chung, <AnandTech May 4th Editorial : AMD's 2000 Roadmap - The Facts anandtech.com > Welcome aboard. Nice article from Anand. thanks for posting the link. <The remaining question is what happens when you overclock the Celeron to 850MHz or beyond; only then will the Duron have problems keeping up because it currently takes an Athlon 800 or an 850 to match or beat the performance of a Celeron overclocked to 850MHz on a BX board.> This doesn't make sense to me. I cannot see any realistic scenario or any MHz where Celeron would outperform Spitfire.Does anyone? <The assumption has always been that, upon the release of the Thunderbird, everyone would be running motherboard platforms with DDR SDRAM support, but unfortunately, that won't be the case. Remember that we just said that the only two available platforms for Socket-A processors at the launch of the Duron/Thunderbird will be the AMD 750 and the VIA KZ133. We already know that the AMD 750 doesn't support DDR SDRAM, and as we made it a point to mention twice above, the KZ133 is nothing more than the KX133 with support for Socket-A. This translates into no DDR SDRAM platforms available for the Athlon at the launch of the Thunderbird ? don't kill the messenger.> "shooting the messenger", I wonder if Anand was reading this thread ;-) Anyways, it kind of felt a little bit of Deja Vu to me so I went back to check if we had this discussion before. Well, what do you know, we did and the discussion was a bit more polite then. What a difference 40 points make! Message 12989446 Message 12989474 Message 12989512 Chuck
