With less than a month to go until AMD makes official the desktop version of the Llano accelerated processing units (APUs), a Chinese website managed to get its hands on such a chip and test its performance in the popular 3DMark Vantage application.

The Llano APU was clocked at 2.4GHz and was tested in all the three profiles included in Futuremark's 3DMark Vantage (performance, high and extreme) as well as in 3DMark 06.

The results speak for themselves and place the APU right below Intel's 2.93GHz Core i3 530 and the 2.6GHz Phenom X4 810 in terms of computing power, while its on-die graphics core performs about the same as the standalone Radeon HD 5550.

According to Nordic Hardware, the integrated GPU found inside the Llano chip tested features 400 stream processors clocked at 600MHz.

In comparison, the Radeon HD 5550 packs 320 stream processors and comes clocked at 550MHz, but its dedicated on-board video buffer memory is faster than the DDR3-1600MHz system memory used by Llano.

AMD's Llano APUs are based on the K10.5+/Husky x86 architecture and the quad-core desktop chips will be paired together with a BeaverCreek on-die GPU that can pack 320 or 400 stream processors while the dual-core models come with the WinterPark graphics unit that features 160 stream processors.

The chips also sport an integrated dual-channel DDR3 memory controller, a PCI Express controller, up to 4MB of cache and select processors pack AMD's Turbo Core 2.0 dynamic acceleration technology as well as a Hybrid CrossFireX graphics support.

Computer manufacturers can choose to pair the APU with AMD A70 or A75 chipsets, which both offer similar features outside of native USB 3.0 support which is only found in the A75 FCH.

The first desktop AMD Llano accelerated processing units are expected to arrive on June 14.
