Llano Processor - The concept of AMD Fusion processor is simply a processor that not only has the CPU chip but also the GPU chip in a processor package. By adding a third component that is the northbridge chipset, will get an AMD hardware called APU (Accelerated Processing Unit).
The concept of AMD Fusion processor is simply a processor that not only has the CPU chip but also the GPU chip in a processor package. By adding a third component that is the northbridge chipset, will get an AMD hardware called APU (Accelerated Processing Unit).
Family members of AMD's first Fusion processor is AMD Zacate and Ontario with a platform called Brazos. Brazos own platform is intended for desktop systems or mobile entry-level with low power consumption and affordable price.
Only in the intervening few months, AMD's Fusion processors re-release of their second, Llano. AMD Llano Lynx is equipped with a chip platform named CPU and GPU is more powerful than the previous Fusion processor. Desktop system or mobile mainstream classes become the main target of AMD Llano
AMD Llano APU consists of three main components namely chip CPU, GPU, and northbridge. The picture above shows you a schematic diagram of the die APU AMD Llano. To see more of each unit from AMD Llano, see the explanation below.
Processors
Husky is the codename given to AMD x86 computing unit at Llano AMD processors. While the K10 architecture used is the "Stars". Processor architecture is actually not entirely new because this architecture has been used in previous generations of AMD processors like the AMD Phenom series.
Although the architecture used is not entirely new, AMD made several improvements to the x86 computing units in Llano such as use of AMD's 32 nm fabrication process. The advantage a smaller fabrication process is the power consumption and hardware working temperature is lower. AMD also increases the size of the L2 cache from 512KB to 1MB for each core processor. AMD claims performance improvement of about 6% on the same clock than the previous generation processor. It seems the processor in question is the AMD Athlon series I / II because the two processors is equally not have the L3-cache.
Llano AMD planned to be released in several variants, namely the series A8, A6, and A4. A8 Series is a series of high-end AMD Llano with four cores and the GPU 400 Stream Processors, A6 series is AMD Llano with four and three-core and 320 Stream Processor GPU, and A4 series with two processor cores and 240 Stream Processor GPU. Currently, only AMD and A6-A8-3850-3650 the newly released to the market.
Graphics Card
AMD graphics computing Llano entrusted to an integrated graphics card with codename Sumo. There are two variants of Sumo who was present at this time, an AMD processor AMD HD 6550D in the A8 series Llano and Llano AMD HD series 6530D at A6.
AMD HD HD 6550D and 6530D using Redwood architecture that has been updated. Redwood architecture itself was first used in the desktop graphics card AMD HD 5670, HD 5570 and HD 5550. Therefore, not surprisingly, AMD HD 6550D have similar specifications as the HD 5570 and HD 5670/HD 6530D have similar specifications as the HD 5550, except in the specification of the GPU clock.
In addition to the GPU clock specification, the other differences that we encounter is the AMD HD HD 6550D and 6530D have used the 32 nm fabrication process. AMD has also improved version of UVD (Unified Video Decoder) from version 2.0 to version 3.0. UVD 3.0 inherits the format support that has been supported by the UVD 2.0 added support for other formats such as Multi-View Codec (Blu-ray 3D), MPEG-2 and MPEG-4 part 2 (XviD / DivX).
Memory requirement is AMD HD HD 6550D and 6530D be obtained from the system memory. AMD HD HD 6550D and 6530D will take some system memory capacity and the size of this capacity can be adjusted via the motherboard BIOS menu. The use of system memory would have an effect also on the type of memory and a memory clock AMD HD HD 6550D and 6530D. Memory type is DDR3 memory clocked to 1866 MHz and the memory bandwidth of 128-bits.
You still remember the feature Hybrid Crossfire? Hybrid Crossfire feature allows add-on graphics card and integrated graphics cards running in multi-GPU mode so graphs can increase computing performance. Llano AMD also has features such as the new "Dual AMD Graphics" or can also be called Asymmetrical Crossfire.
This feature is quite interesting because Llano Lynx AMD platform users can increase computing performance by adding a graphics add-on graphics card. However, there are some limitations on this feature. The first is an add-on graphics cards that are used should have a maximum of two times the performance of graphics card performance Sumo. In the above table, the add-on graphics cards that can be combined with the AMD HD HD 6550D and 6530D is the HD 6450, HD 6570 and HD 6670. While the second is a feature of AMD Dual-Graphics is more optimal for use in applications or games based on DirectX 10 and 11.
Power Gating
The combination of AMD Athlon CPU chip class II and HD 5000 series GPU chip would need a good power management mechanisms that TDP processor does not exceed the maximum specified value. AMD Llano APU uses the power saving mechanism, called "Power Gating". Simply put, "Power Gating" will cut off power in a unit if the unit is off / not working (idle). APU equipped with two AMD Llano switch "Power Gating" respectively to the CPU and GPU chips.
The picture above can explain how the "Power Gating" on AMD's APU Llano die work. Seen here the difference when the entire AMD Llano APU unit is switched on or when one unit of experience "Power Gating" because the unit is off. Even the "Power Gating" on the CPU unit can be adjusted further so that the "Power Gating" can be done in each processor cores are inactive. Not only the CPU chip and GPU, UVD units were also able to perform "Power Gating" on their own units.
Turbo Core Technology
This feature allows the processor to raise the CPU clock speed over the default clock for the processor limitations (such as the TDP or the working temperature) has not been achieved. For example, AMD-3800 A6 with the default CPU clock of 2.4 GHz CPU clock can be re-increase of up to 2.7 GHz.
Increasing the CPU clock itself depends on the activity of processor cores. The less active processor cores, the higher the increase in CPU clock on the processor cores are active. Therefore, a more optimal Turbo Core features used for applications that do not use the entire processor cores. To activate this feature, make sure the power saving feature that is a la AMD Cool n Quiet is active.
Northbridge
In AMD platform Llano Lynx, AMD northbridge chipset move into the processor die. Northbridge chipset is responsible for providing PCI Express lane and bridge the communication with the CPU and GPU memory. Llano AMD's memory controller designed to accommodate high-speed memory to support memory speeds up to 1866 MHz. High-speed memory bandwidth plays an important role in AMD's GPU performance as well as Llano. In case of default, the memory clock is used at 1333 MHz. You simply change the memory multiplier in the BIOS menu so that the memory can run at speeds of 1866 MHz (of course if the memory used to support such speeds).
PCI Express lane is available on the AMD platform Llano Lynx is available in 24 pieces. Sixteen lane PCI Express graphics cards are allocated to the needs of the add-on. This pathway can also be subdivided into two pathways (x8; x8) multi-GPU configuration for CrossfireX. Four other pathways are used as channels of communication with the chipset FCH (Fusion Controller Hub) or southbridge. While the remaining four lane PCI Express can be allocated for other needs such as extra PCI Express slot, USB 3.0 line, and so on.
FCH (Fusion Controller Hub)
Since the chipset northbridge is integrated into the die AMD Llano, Llano in the AMD motherboard chipset Southbridge only remaining here or call FCH AMD (Fusion Controller Hub). AMD chipset provides two types of FCH, an AMD A75 and A55.
AMD A55
Maybe you will ask, where is the difference between the chipset AMD A75 and A55? Difference A75 and A55 AMD chipset is actually located in the feature of SATA and USB. AMD A75 which is a high-end chipset AMD Llano equipped feature 6Gbps SATA III, and four USB 3.0 ports. While AMD A55 only has features SATA II 3Gbps and USB 3.0 feature is removed. But this does not preclude the motherboard manufacturer to add features 6Gbps SATA III and USB 3.0 using an additional chip on the motherboard AMD A55.
AMD's new processor socket Llano using named FM1 (905-pin). This certainly makes the new socket AMD Llano not be used on the previous generation of AMD motherboards still use the socket AM3/AM2 +. The good news is you can still use your old cooler AMD processors in the AMD motherboard Llano.
Motherboard led chip A75 FCH is ready we are testing with AMD processors Llano who also has landed on our test lab, an AMD A8 and A6-3850-3650. As to whether the performance of AMD's latest platforms this? Wait for more test results remain at soloreview.
