We've already covered in detail the launch of the new Llano of AMD architecture. If you have not yet read dedicated article in the new APU of the caster, and specifically to their declination for laptops, the Sabine platform, we cannot advise too you to take a glance before continuing.Two weeks after products for laptops, AMD now launches its Llano APU for desktop, i.e. platform Lynx. View our previous article, we will primarily devote today record benchmarks and analysis of performance: but wait for Dual Graphics? What is the comparison to the Intel Sandy Bridge with separate graphics card? What are the effects of the performance of the memory on the games? USB 3.0 makes better or worse than the controllers cards we tested previously?Before answering these questions, do any of even a quick overview of the first APU Llano for desktop computers.
Llano: APU on a small budget
Audi must be proud (Finally, perhaps not, seen the character "entry" of these processors): AMD uses the A6 and A8 prefixes to distinguish the felt performance four first models launched today.Among these four processors, there are no surprise two A6 and A8 two. The most powerful is theA8-3850, an APU with a TDP of 100 watts, a Radeon HD 6550D graphics engine, four cores of execution (still based on the Stars architecture) each with a frequency of 2.9 GHz and 1 MB L2 cache. The Turbo Core function is not available: the only way to overcome this frequency is overclocking. Side price, AMD refers to a rate of about $135.
A6-3650 is also equipped with a TDP of 100 watts, four cores, a total of 4 MB of L2 cache and a controller taking memory supports DDR3-1866, like its big brother, but it contains a graphics engine Radeon HD 3650D and displays an a no more low frequency, namely 2.6 GHz (and again)(, the Turbo Core is not accessible). It should cost around $115; remains to be seen that this will once the conversion into euros carried out.

The other two models are 65 watts from the first two declensions. We note with interest that this less generous thermal envelope seems hardly handicap them:A8-3800 contains the same graphics engine, the same number of cores and the same amount of L2 cache as the A8-3850; only the frequency of the CPU portion fell to 2.4 GHz, and yet, it is offset by the Turbo Core, present this time, which allows in theory up to 2.7 GHz when the processor heats not too. AMD does unfortunately sent us any copy of this function of acceleration.Finally comes theA6-3600, also a 65 Watt model, which is different of the A6-3650 by its reduced to 2.1 GHz CPU frequency (but 2.4 GHz when the Turbo Core is active).
With the graphic part, the difference between the Radeon HD 6550D and Radeon HD 6530D is, broadly, a SIMD engine (and a reduced frequency).

Just look at the schema of the Llano GPU portion to understand how AMD differentiates two products. Each SIMD engine contains 80 ALU and is associated with 4 texture units. by disabling a firm transforms the Radeon HD 6550D a Radeon HD 6530D.
A small loads and already a delay
While the initial launch of the Lynx (Llano to desktop) platform contained already four models, AMD has just announce that models 65 watts, i.e. the A8-3800 and the A6-3600, would be available only later, at an indefinite date. We have therefore more than two processors to test, the A8-3850 and the A6-3650, two 100-Watt models and without Turbo Core.
