Advanced Micro Devices company will launch its Athlon XP "Barton" processors with 400MHz PSB later this Spring we have been told a number of times already as well as shared this information with you. The only question remaining was about core-clocks of the CPUs, but fortunately today HardTecs4U web-site published the figures at last.

According to the report you can read over here, the Athlon XP 3200+ will be clocked at 2200MHz, while the Athlon XP 3000+ with 400MHz FSB will function at 2100MHz. The chips will boast with 512KB of L2 cache and will be made using the same 0.13 micron fabrication process as predecessors at the same Fab30, like all the latest AMD CPUs.

With the transition to the new FSB speed, the model 3000+ will loose 67MHz of its original core-clock what will decrease its performance in application where frequencies are important. The model 3200+ will gain about 33MHz what will pump its speed up in nearly every application you can imagine.

Remember that sometimes AMD changes the core-clocks of its processors even after it is published in some of its documents for using inside the company and among resellers.

Currently SiS has already announced its SiS748 chipset with 400MHz FSB support, later this year VIA and NVIDIA will also offer its core-logic for processors with 400MHz EV-6 bus.
