Advanced Micro Devices has already initiated its first value processors with 64-bit capability, just a couple of weeks after its larger rival Intel Corp. officially introduced its Celeron D processors with the same feature. With both AMD and Intel supplying 64-bit chips across all market segments, the era of 64-bit computer should be considered as ongoing.

“As of today AMD has 64-bit enabled Sempron processors available. Customers will be able to tell the difference between the 32-bit only and 64-bit enabled Sempron processors by the OPN number,” AMD’s spokesman Damon Muzny told X-bit labs.

The AMD Sempron chips in 754-pin form-factor have integrated PC3200 memory controller and also support NX-bit security capability. Particular specifications of AMD Sempron processors with 64-bit capability, such as clock-speeds and cache sizes, are not reported, but they should be similar to central processing units with the same processor numbers, but with no AMD64 enabled.

The lineup consists of AMD Sempron processors with model numbers 2600+, 2800+, 3000+, 3100+ and 3300+ in PGA754 packaging. The 64-bit AMD

Sempron processors 2600+, 2800+, 3000+, 3100+, and 3300+ are priced at $74, $83, $98, $113, and $140 respectively, which is a bit higher compared to chips with similar characteristics, but without AMD64.

China’s largest computer maker Lenovo has already received the first batch of 64-bit enabled AMD Sempron processors.

“Lenovo Group, China’s largest PC company, will begin offering 64-bit-enabled AMD Sempron processor systems in China,” Mr. Muzny added.
