They Say

“AMD Direct Connet Architecture,an award-winning technology designed to reduce bottlenecks that can exist when multiple components compete for access to the processor bus. Competing x86 systems use a single front-side bus (FSB) which must carry memory access, graphics, and I/O traffic. Eliminate the FSB, and you can reduce delays that competing access requests can cause.” “Lithography is the printing process used to manufacture processors. When we say we manufacture a device at 90 nanometers (nm), that number corresponds to the International Technology Roadmap for Semiconductors’ (ITRS) definition of the minimum metal pitch – the smallest metal “lines” – used. These tiny proportions allow AMD to etch onto a silicon die complex circuits of millions upon millions of transistors, which allow for more-powerful-but-smaller processors. AMD uses a combination of 248nm and 193nm lithography tools, along with resolution enhancement techniques, to etch sub-50nm transistor gates – the smaller transistors switch faster and draw less power.”

"This new core should not only allow replacing the Winchester in slower Athlon 64 CPU models and adding new functionality to these processors, but also should come to take the place of the Newcastle and ClawHammer cores in the fastest modifications of this processor family. Moreover, the arrival of Venice sets green light to the release of even faster Athlon 64 processor models. In the near future AMD is expected to announce new Athlon 64 4200+ and Athlon 64 FX-57 processors based on Venice and San Diego cores (San Diego is an analog of Venice but with larger L2 cache)."

"Those are the high points of AMD's remodeling job. As we've noted, these changes have wide-ranging implications for Hammer motherboards, chipsets, operating systems, and software. We will, of course, be testing the performance implications shortly."  Scott Wasson (2003)

"The Athlon 64 FX-51 systems notched a PC WorldBench 4 score of 142--the fastest yet. The Athlon 64 3200+ unit from ABS scored 140, and a comparably configured Intel Pentium 4 comparison PC from Alienware managed 126. The scores for three previously tested 32-bit Athlon XP 3200+ PCs averaged 136." Tom Mainelli, (2003)
