The Athlon64 4000+ Comes To Market
One interpretation is that AMD is now setting the shortly-lived performance standards in the AMD and Intel processor performance wars. With the Athlon64 3800+ the chip firm introduced a QuantiSpeed rating that exceeded the clock speed of Intel's fastest processor for the first time. Now, the 4000+ sets another landmark that can be considered a serious challenge for Intel.
Additionally, AMD is phasing in its 90 nm Winchester cores, which are really shrunken Newcastle cores with a 512 kB L2 cache.
AMD is also making the move with considerably less fanfare than when Intel shifted to its 90 nm production process. The company will also initially use the high-volume process to make its lower-speed devices. The downside of AMD's quiet shift to 90 nm is that you will have to study the data sheets in order to tell the 130 nm and 90 nm versions apart as the processors' packaging and documentation will not make the distinction.
Since AMD's 90 nm Athlon64 3500+ is rated at 67 W, while the 130 nm part consumed a maximum of 89 W, we expect the new core to be able to finally hit the 3 GHz barrier within six months. However, the race to 3 GHz also depends on how fast Intel can get back on the high-clock speed road again, and entice AMD to offer even faster processors.
