We will conduct further tests with the system and are planning to deliver a full review in the near future. Even though the company changed seven processor sockets (754 to 939, AM2, AM2+, AM3 and now AM3r2 and FM1 for Fusion), you can use the identical heatsink at default clock. We deliberately used the oldest AMD heatsink we could find to demonstrate just how upgradeable AMD’s ecosystem is. You might have noticed that we used an seven year old Thermaltake K8 Silent Boost cooler, originally designed for first Athlon 64 processors. It might not be the optimal choice for such a low power system, so a weaker power supply with higher efficiency at those levels might lower consumption by a few more watts. The system was powered by a 600W Silverstone Strider ST60F power supply, which is rated at 80-85% efficiency at 20-100% load. For reviewing purposes we ran a minimal system configuration with only one HDD, USB keyboard and mouse attached to the system. The mainboard we employed is a Gigabyte A75M-UD2H ♚TX board running BIOS F3b. We feel that AMD left plenty of headroom for overclocking, but actually it turns Fusion into a majestic power saver.Īll power figures presented here are measured at the wall outlet for the complete system. However, full load going from 209 to only 142 Watts for the whole system is something that sparks our interest – if you can keep the system running at this power level, you’re saving 32% of your annual computer power bill, which is not a small change regardless of the country you live in. Running idle, power drain dropped to 55.6W, which is only a minor improvement, since most savings come from power gating in this state. As you can see on the CPU-Z screenshot, with this setting, the CPU cores were operated with only 1.136V (note that due to how VIDs work, this is actually -0.288V). Adding GPU load to that raised it to about 142W. With only the CPU cores loaded power consumption was down to 123W. With our stable setting though, it ran the CPU and GPU stress tests without a hassle. When we set the voltage offset to -0.3V the system crashed with a blue screen. We toyed around a bit and finally achieved a stable -0.275V undervolt. Undervolting from 1.42 to 1.13V resulted in significant decrease of power consumption In idle mode the CPU cores clock down to 800MHz at 1.024V though.

When additionally loaded with a GPU burn-in test (we used MSI Kombustor test), the power consumption tops out at 209W for the whole system. This is up from a rather impressive 59W when running idle on the Windows desktop.
When put under full load using Prime95 “In-place large FFTs” stress test, the power consumption rises to 184W. For comparison, Intel’s 32nm Core i3-2100 pulls in 1.1 Volts. You have to know that the default voltage at 2.9GHz is 1.424V, which is quite a lot considering that Llano is manufactured on a 32nm SOI process. Thermaltake K8 Silent Boost, Socket 754.Our test system is based on following components: Instead of overclocking, we ventured the other way and came to quite remarkable results with undervolting the APU. While we aren’t finished with our testing, we wanted to check just how far AMD went to make sure the glueing of K10.6 CPU would go with the world’s first SOI-based GPU.
We recently received a review sample of AMD’s recently introduced A-series APU A8-3850.
