Conclusion: High Efficiency for Multi-Core Applications
Does a low-power version of a quad-core CPU make sense if it runs at a clock rate as low as 1.80 GHz?
This CPU is definitely not recommended for gamers, but users who work with multi-core-capable applications and give importance to low power consumption will enjoy the AMD Phenom X4 9100e. After all, this CPU is unmatched in terms of power efficiency. When all four computing cores of the 9100e are under load, it is more efficient than the Phenom X3 and previous Phenom X4 CPUs. Thus, the Phenom X4 9100e is suitable for video and 3D rendering.
AMD has reduced the power loss of the low-power Phenom so much that compared to the conventional Phenom X4, it cuts the equivalent power consumption of one computing core.
We were able to overclock the Phenom X4 9100e by 33% without increasing the core voltage. At present, the chipset prevents further overclocking.
The low-power Phenom demonstrates that AMD is capable of substantially reducing the power consumption of its quad-core CPUs by optimizing the manufacturing process.
When clocked to the level of the Phenom X4 9750, the Phenom X4 9100e consumes 30% less energy, while providing the same computing performance.
The AMD overclocking community would surely be happy about a Black Edition with an unlocked multiplier.
