AMD is preparing the launch of its next-generation K10-derivedStars-family single, dual and quad-core processors. The next-generation Stars-family splits into three different brand names – Phenom, Athlon and Sempron. Ringing in the flagship is three Agena FX-based AMD Phenom FX processors. AMD has yet to confirm clock speeds for the three models; however, the latest roadmap reveals ballparks for the processors.
The top-end AMD Phenom FX processor clocks in the 2.4-2.6 GHz speed range. Slotting below the top-end Phenom FX is a 2.2-2.4 GHz model. These two models occupy AMD’s upcoming Socket 1207+ and current Socket 1207 Quad FX platforms. AMD also has a Phenom FX for single-processor customers as well, clocked at 2.4-2.6 GHz.
AMD further differentiates its Phenom FX processors with different Hyper Transport 3.0 clock speeds. The flagship 2.4-2.6 GHz model features a 3.6 GHz HT 3.0 clock speed while the two 2.2-2.4 GHz models have a lower 3.2 GHz HT 3.0 clock. All three models share the same 4x512KB L2 cache and 2MB L3 cache configuration. AMD has yet to determine the TDP of its Phenom FX processors yet.
Catering towards high-end user are two Socket AM2+ AMD Phenom X4 processors. AMD remains undecided on its model numbers; however, clock speeds on the Agena-based Phenom X4 processors are set. The two AMD Phenom X4 processors clock in at 2.4 GHz and 2.2 GHz. These models share the same 4x512KB L2 cache and 2MB L3 cache configuration as the Phenom FX processors.
HT 3.0 speeds differ on the two models, the 2.4 GHz features a 3.6 GHz HT 3.0 speed while the 2.2 GHz model features a 3.2 GHz HT 3.0 speed. AMD rates the Phenom X4 processors with 89W TDPs. AMD plans to start taking orders for its Phenom FX and Phenom X4 processors in Q3’2007.
AMD’s dual-core Kuma processors will carry the Phenom X2 name and drop into Socket AM2+ and AM2 motherboards. There are three AMD Phenom X2 processors in the pipeline with 2.8 GHz, 2.6 GHz and 2.4 GHz clock speeds. HT 3.0 speeds vary on the AMD Phenom X2 processors. At the top with the AMD Phenom X2 2.8 GHz model, the HT 3.0 bus clocks in at 4.2 GHz – higher than the Phenom FX and Phenom X4 models. The two lower models have 3.8 GHz and 3.6 GHz HT 3.0 clock speeds, respectively.
All three models feature a 2x512KB L2 cache and 2MB L3 cache configuration. The higher end 2.8 GHz has an 89W TDP, similar to the Phenom X4 models while the 2.6 GHz and 2.4 GHz receive a lower 65W TDP rating. AMD plans to take orders for its Phenom X2 processors beginning in Q4’2007.
If low power is a concern, AMD intends to offer three low power AMD Phenom X2 models. Three AMD Phenom X2 occupy the low power dual-core lineup. AMD rates these models with 45W TDPs. The low power Phenom X2 clock in at 2.3 GHz, 2.1 GHz and 1.9 GHz with 3.4 GHz, 3.0 GHz and 2.8 GHz HT 3.0 speeds, respectively.
Although AMD plans to launch its new Phenom branding for high-end processors, the Athlon 64 X2 name lives on with Rana. There’s one Rana model in the pipeline clocked at 2.2 GHz. The Rana-based Athlon 64 X2 does away with L3 cache and only has 2x512KB of L2 cache, differentiating it from the Kuma-based AMD Phenom X2.
At the bottom of the Stars-family are the Spica Sempron models. Two Spica Sempron models occupy AMD’s value lineup. The new Spica Sempron models clock in at 2.4 GHz and 2.2 GHz with 512KB of L2 cache. As with the dual and quad-core products, the two Spica Sempron models have 3.6 GHz and 3.2 GHz HT 3.0 clocks, respectively. AMD rates the Spica Sempron models with 45W TDPs, as with the low power Phenom X2 models.
AMD plans to take orders for its low power Kuma Phenom X2, Rana Athlon 64 X2 and Spica Sempron models beginning in Q1’2008.
