AMD KAVERI-Difference and Improvement

AMD has released one generation Latest APU, the AMD Kaveri.Dynasty APU (Accelerated Processing Units)AMD finally stepped on the fourth generation in the early 2014's. Following Llano, Trinity, and Richland, Kaveri APU finally startdebut on January 14, 2014. This date also marks the Kaveri APU start of the sale throughout the world. I think each generation of AMD APU is always eagerly anticipated by fans, even when the new Richland news release Kaveri has begun busy talking in the online forums.APU is generation that means processors from AMD Accelerated Processing Unit which is a merger between the technology Central Procesing Unit (CPU) with Graphic Processing Unit (GPU).

long wait finally paid, a processor integrated with the GPU is equipped with the best technology AMD. In the APU Kaveri have invested around the best technology owned by AMD today. Even a number of technology latest generation of the APU Kaveri have never even if used on AMD processors advance on A- Series and FX Series. curious about the technology latest generation in the APU Kaveri?

In the APU Kaveri, AMD introduced what is called Compute Cores( CC). APU Kaveri highest type has 12 Compute Cores where the 4 CC comes from the unit CPU and 8 CC other derived from the unit GPU. Simply put, Compute Cores is a computing unit( CPU+GPU) in the APU Kaveri to run applications compute- enable such applications with the support OpenCL and others. APU Kaveri have adopted the fabrication process the latest AMD, which is 28 nm. AMD build APU Kaveri by using 2, 41 billion transistors with die size processor for 245 mm². In comparison, APU Trinity/ Richland to the size of die processor 246 mm², only has 1, 303 billion transistors. This means, to die size processor approximately the same time, AMD managed to enter the 85% more transistors. From 2, 41 billion transistors, 47% of which allocated to the unit GPU.

AMD Kaveri APU consists of computational units
x86/x64 (CPU) architecture steamroller
computing and graphics units (GPU) with
architecture GCN (Graphics Core Next). Type
The highest Kaveri APU processors will be equipped
CPU and GPU are two modules steamroller
with 8 CU (Compute Units). One thing
Kaveri is interesting from this APU has
adopt Huma (Heterogeneous Unified
Memory Architecture) memory
controller. Simply put, Huma memory
controller is a memory controller
be shared between the CPU and
GPU. Huma memory controller very closely
conjunction with HSA feature
(Heterogeneous System Architecture).


APU Kaveri adopted the unit CPU architecture Steamroller. Unexpectedly, CPU architecture successor Bulldozer and Piledriver the start the debut on the processor APU A- Series. This little different from the Piledriver where the debut began in the processor AMD FX series, then continued on the APU A- Series Trinity and Richland.

Architecture CPU Steamroller still carries the scheme modules such as Bulldozer and Piledriver. In the one processor module there are two integer core, one floating point core, and L2 cache size 2MB. One significant changes in Steamroller is the presence of two units decode on a single processor module. Two units decode the work in parallel in dealing with two integer core and one floating point core. In Piledriver, one processor module has only one unit decodes the deal with two integer core and one floating point core. The existence of two units decode the deal with two integer core make computing performance integer core increase.

On Steamroller, AMD also increase the size of L1 intruction cache of 64 KB be 96 KB but still maintaining the size of L1 cache data by 16 KB. Meanwhile, the use of L2 cache is now can be set based on the burden of the use. As a result a number of the L2 cache can be turned off when not used so that can reduce power consumption.


AMD APU Kaveri using the processor socket type of the latest FM2+. Processor APU socket FM2+ need a motherboard with socket type similar. As a result processor APU socket FM2+ can not be used on the motherboard socket FM2. Interestingly, the processor APU socket FM2 can be used on the motherboard socket FM2+. As the socket FM2, it is possible socket FM2+ also used on two generation.

PCIe 3.0

In addition to the use of the latest processor socket type,Kaveri APU platform has now become a platform prime AMD with support for PCI Express3.0. To enable support for PCI Express
3.0, FM2 motherboard + must be paired with Kaveri APU. PCI Express 3.0 offers twice the total bandwidth PCI Express 2.0 or up to 15.75 GBps on the PCIe x16 slot.

Chipset / FCH (Fusion Controller Hub)

Motherboard socket FM2 + present use chipset A88X, A85X, A78, and A55. A number of The difference between these chipsets such as CrossfireX feature support, USB support 3.0, and SATA III 6Gbps support. Type The highest such A88X chipset will have
The entire feature while type cheapest only 3Gbps SATA II equipped and does not have USB 3.0 feature.

Platform FM2+ equipped a feature unique named Configurable TDP. Featured can be found on the menu motherboard BIOS socket FM2+ when paired with the processor APU Kaveri. Featured Configurable TDP allows users to lower value TDP processor APU Kaveri. Impairment TDP is usually will make the processor work with power consumption and working temperature lower. Unfortunately, according to AMD, although this feature can work on almost all the processor type APU Kaveri but feature Configurable TDP more optimized for type A8- 7600 that has two values TDP.

As previous generation, cooling system" typical" APU inikembali given to the sales package processor A10- 7850K and A10- 7700K. For the working temperature processor lower, use the cooling system processor 3rd- party with the ability to better.
