Specifications

Iím not going to go into too much detail on the specs because Iíve already taken a look a number of different TBird processors that all have the exact same core architecture.
Speed: 1.4GHz
Font-side Bus: 133MHz DDR (effectively 266MHz)
Fabrication Process: 0.18 micron, Aluminum or Copper Interconnects
Number of Transistors: 37 million
Processor Die Size: 117 mm2
L1 Cache Size: 128KB
L2 Cache Size: 256KB
L2 Cache Speed: 1:1 Core Speed
L2 Cache Path Width: 64bits wide
L2 Cache Organization: 16-way set Associative
Voltage: 1.75V
Supported Chipsets: AMD 750, AMD 760, AMD 60MP, VIA Apollo KT133, KT133A, KT266, ALi MAGiK1.

Yesterday I talked about the Athlon processorís point-to-point transaction bus and its advantages. I talked about how it enables the Athlon to command its own independent bus in a multi processor system like the one based on the 760MP chipset. With this in mind, the current TBird is also ready for use in a 760MP or future dual socket A motherboards.

If your motherboard supports it, just plug in the 1.4GHz and go. There shouldnít be any fuss should you have the right hardware requirements to begin with.

AYHJA Athlon


With the release of the 1.4GHz Athlon, we notice a new processor stepping code on the core with the letters AYHJA. The last stepping that was famous for its overclocking ability was the AXIA stepping. We had people who could get 1GHz AXIA Athlon processors to speeds that were pretty close to 1.5GHz. Can the new stepping compete?

To test, I used the Iwill KK266 KT133A based motherboard. Raising the FSB and multiplier together, I achieved a setting of 143MHz FSB * 12X multiplier. What does this give me exactly? 1.71GHz of pure Athlon power!

Again, we have another stepping capable of pushing the speeds envelop. Weíll see how it performs in just a sec.
