AMD today unveiled a new family of low power server processors: the AMD Opteron X-Series optimized for scale-out server architectures. Formerly known as "Kyoto," the first AMD Opteron X-Series processors "are the highest density, most power-efficient small core x86 processors ever built," according to AMD. The company claims that the new X1150 and X2150 processors beat the top performing Intel Atom processor on key performance benchmarks, including single thread and throughput performance with superior power-efficiency, twice the cores and L2 cache with a more advanced pipeline architecture, higher integration and support for up to 32 gigabytes of DRAM?4x more than the Intel Atom processor.

	AMD Opteron X-Series	Intel Atom S1260	AMD Advantage
x86 CPU Cores	4	2	2X
GPU Cores	128 AMD Radeon HD 8000 Cores	None	AMD Only
Max. DRAM Per Socket	32 GB	8 GB	4X
Max. DRAM Speed	DDR3-1600	DDR3-1333	1.2X
L2 Cache	2 MB	1 MB	2X
Throughput Performance	28.9 @ 2 GHz (CPU) (est.)	13.0 @ 2 GHz	2.2X
Single Thread Performance	10.0 @ 2 GHz (CPU) (est.)	5.2 @ 2 GHz	1.9X
Integrated SATA Ports	Yes	No	AMD Only

The AMD Opteron X-Series processors come in two variants. The AMD Opteron X2150, which consumes as little as 11 watts, is the first server APU system-on-a-chip integrating CPU and GPU engines with a high-speed bus on a single die. This enables server bulders to take advantage of AMD Radeon HD 8000 graphics technology for multimedia-oriented server workloads. The AMD Opteron X1150, which consumes as little as 9 watts, is a CPU-only version optimized for general scale-out workloads.
