AMD unleashes 65nm beginning in December

AMD’s long awaited 65nm Brisbane core products are just around the corner. DailyTech previously reported that Brisbane is expected to launch in December. AMD’s latest roadmap shows Brisbane 65nm products will arrive as scheduled. Brisbane will be AMD’s first 65nm core and is expected to launch with four parts. The four 65nm Brisbane core based products include the Athlon 64 X2 5000+, 4800+, 4400+ and 3800+. All four models will have 2x512KB of L2 cache and a 65W TDP rating.

Two additional products will switch over to the Brisbane 65nm core in Q2’2007. This includes the Athlon 64 X2 5200+ and 5400+. The Athlon 64 X2 5600+ will be clocked at 2.8 GHz with a 2x512KB L2 cache configuration. Unlike the lower Brisbane products it will have a 76W TDP rating. AMD’s Brisbane based Athlon 64 X2 5200+ will differ from the current Windsor offering. Instead of the 2.6 GHz clock speed and 2x1MB L2 cache configuration of the Windsor based Athlon 64 X2 5200+, the Brisbane based Athlon 64 X2 5200+ will have a 2x512KB L2 cache configuration and 2.7 GHz clock speed. The Brisbane Athlon 64 X2 5200+ also has a 65W TDP like other Brisbane products.

Also arriving in Q2’2007 is energy efficient Brisbane based products. These Energy Efficient processors will have a 35W TDP and be available in Athlon 64 X2 4200+, 4000+ and new 3800+ models. Joining the energy efficient product lineup in Q3’2007 will be the Athlon 64 X2 4400+. The energy efficient Athlon 64 X2 4400+ carries the same 35W TDP as the other low power Brisbane products.

AMD’s dual-core product lineup isn’t the only lineup switching over to 65nm. Single-core Athlon 64 products based on the 65nm Lima core will arrive in January 2007. Two initial single-core Lima products will be introduced. These products are the Athlon 64 3800+ and Athlon 64 3500+. Joining the 65nm single-core party in Q2’2007 is the Athlon 64 4000+. All single-core Lima based products carry a 45W TDP rating and have 512KB of L2 cache.

Not to be left out of the 65nm transitions is the Sempron product lineup. In Q2’2007 AMD will release four 65nm Sparta based Sempron products. The Sempron Sparta based lineup includes the 3800+, 3600+, 3500+ and 3400+ clocked at 2.2 GHz, 2.0 GHz, and 1.8 GHz respectively. All four Sparta based products carry a 35W TDP. Three of the Sparta based products have 256KB of L2 cache while the Sempron 3500+ only has 128KB of L2 cache.

AMD is just cutting itself some slack. The 2.3GHz parts will likely get close to the 35W power draw but the 2GHz parts could, for example, use 25W. The nice thing about rating all of these for 35W is that manufacturers can design systems for 35W parts and use the whole range of parts, and any future 35W AMD releases. Then there's also the fact that some chips may actually draw more power than normal and get close to 35W even at 2.0GHz, and if these don't fit the low-power TDP they'd have to be released as 65W parts.

"AMD is just cutting itself some slack. The 2.3GHz parts will likely get close to the 35W power draw but the 2GHz parts could, for example, use 25W."

What you suggest is the typical way that things work, although 25W at 2GHz seems a bit optimistic; 30W seems more likely to me.
It also gives them headroom if they struggle to produce many 35W chips at 2.3GHz. In this case the chips below 2.3GHz could actually produce 35W, rather than it being a max figure for the range of chips which is normal practice.
I’m not saying this to criticise AMD, but because they seemed to have struggled in producing many EE chips at 90nm, especially the 35W version. This isn’t surprising and AMD resorted to factory under-volting the 90nm X2 EE chips; the 35W EE SFF was unsurprisingly even more heavily undervolted than the 65W EE chips.
The very poor availability of the 35W EE SFF chip makes me think that they were cherry picked and that they had trouble in finding many that could match the specs.
At 65nm they are obviously more confident as they are offering higher speeds and a wider range of chips. That good news provided they can deliver this time and the pricing isn’t as exorbitant as well.

Incidentally, you can undervolt almost all current AMD chips using software and achieve results similar or even better than that obtainable with the EE chips and save money at the same time. Just don’t expect to match the 35W of the EE SFF chip though.
