AMD revealed back in July that the first Fusion APU will launch in Q4. The first will be the mobile Ontario circuit, whose theoretic performance is said to have been revealed by the BOINC project, and it hints of the performance we can expect.

Ontario builds on the AMD Bobcat architecture and will bring integrated DirectX 11 graphics optimized for mobile and energy efficient platforms. The Bobcat architecture will according to AMD be capable of TDPs lower than 1 watt, but the level AMD is aiming for with the first Ontario models is uncertain.


According to an Ontario APU has appeared on BOINC and with dual cores and clock frequency between 1.4 and 1.6 GHz the floating point performance is 1,351 million operations per second, and the integer performance 3,047 million operations per second.

The German site compared the numbers to both Intel’s Atom D510 CPU and AMD’s Athlon II X2 250u and Phenom II X4 965 BE processors. The performance turned out to be double that of Intel’s Atom D510 CPU and not far from the desktop CPU Athlon II X2 250u, also operating at 1,60 GHz.

Processor OS Clock frequency Integer FP Relative performance
Ontario Server 2008 R2 1,40 – 1,60 ? 3,047 GIPS 1,351 GFLOPS
Atom D510 Windows 7 x86 1,66 1,892 GIPS 0,735 GFLOPS 0,58x
Athlon II X2 250u Windows 7 x86 1,60 3,465 GIPS 1,591 GFLOPS 1,15x
Phenom II X4 965 BE Windows 7 x64 3,40 8,452 GIPS 2,792 GFLOPS 2,42x


There is still no concrete information on the power consumption of Ontario and these benchmarks are still unconfirmed, but Ontario could become a real interesting notebook alternative with its relatively powerful DirectX 11 graphics portion, but also for HTPCs and multimedia PCs where Intel Atom has found a niche.
