In an attempt to compete with Intel’s low-power high-performance mobile processors, Advanced Micro Devices is preparing a new flavour of Mobile Athlon 64 processor with seriously reduced power consumption and 64-bit capability.
Web-site CoolTechZone has caught a document accidentally published on AMD’s web-site revealing the company’s intention to introduce Mobile Athlon 64 2700+ microprocessor that would feature reduced thermal envelope of 35W, about two times lower compared to today’s Mobile Athlon 64 processors.
Today’s Mobile Athlon 64 microprocessors for notebooks from AMD are available in three flavors depending on performance level in general and clock-speed in particular; these are models 2800+, 3000+ and 3200+ functioning at 1.60GHz, 1.80GHz and 2.0GHz respectively. The CPUs have 1MB of full-speed on-die L2 cache and single-channel DDR SDRAM memory controller, like the majority of other AMD Athlon 64 processors in 754-pin packaging.
The Mobile Athlon 64 2700+ processor that is yet to be introduced is expected to operate at 1.60GHz, but feature only 512KB of L2 cache. 1MB cache is overwhelmingly large for the majority of software applications available today, therefore, reduced size of the on-die memory bank is not likely to decrease performance of the part dramatically.
Even though AMD positions its Mobile Athlon 64 chips for the market of extremely powerful notebooks, thermal design power of Mobile AMD Athlon 64 processors is 62W – really lot for mobile central processing units. Thanks to PowerNow! And Cool’n’Quiet technologies, the chips consume significantly less electricity under typical load. Nevertheless, AMD still decided to create a version of the Mobile Athlon 64 with thermal design power of about 35W that is likely to be used on truly mobile machines that require low power consumption and extended battery life amid high performance.
Intel’s Pentium M processors specifically tailored for notebooks consume up to 24.5W at 1.70GHz. Intel’s Pentium 4-M processors at 2.40GHz and 2.50GHz typically consume 30W and 35W respectively under maximum load. Mobile Pentium 4 processors that are designed for DTR laptops have TDP of 60W – 76W at clock-speeds from 2.40GHz to 3.20GHz.
Advanced Micro Devices is also preparing 90nm versions of its Mobile Athlon 64 processors. According to the company’s roadmaps, code-named Odessa CPUs is scheduled for introduction the second half of the year. Already in the first half of 2005 AMD is planning to roll-out a microprocessor internally called
Pricing of Mobile Athlon 64 2700+ is not set. AMD did not comment on the report.
