This efficient fusion of CPU and GPU is called APU (Accelerated Processing Unit) and benefits in a special form of the direct connection of the individual components. The AMD A6-7470K belongs to the middle-class models of the latest generation APU named Godavari, a refresh of the preceding Kaveri APUs.
The new JC-Stepping continues to use the Kaveri-based, however, thanks to the optimized manufacturing process increased clock rates for the processor and graphics part with improved overall efficiency. The revised entry-level APU resorts to 1 MB L2 cache and uses it for the processor-Part one of the improved Steamroller modules (total of 2 CPU cores), which are characterized by an increased per-clock performance and extensive feature range, such as AES encryption, AMD-V virtualization technology or SSE and AVX instruction set extensions. The fabricated chip in 28 nm clocked into the basic level of 3.700 MHz and can increase via Turbo Core 3.0 under load and the clock of single cores at up to 4000 MHz. Since it is a Black Edition, also the uncomplicated overclocking via the unlocked multiplier is possible, although this would involve the loss of warranty.
In keeping with the modern architecture of the CPU graphics chip, the silicon includes a total of five whole computing units, divided into the two mentioned 64-bit CPU cores (1 module) and four "compute units" of the graphics unit (256 Shaders) with 800 MHz clock. The larger graphic part of the team collected almost half of the total chip area and has the strongest growth compared to its predecessor. He comes here therefore in the form of an integrated Radeon R5 series. The architecture is based is called GCN (Graphics Core Next) and place both in the dedicated Radeon graphics cards in the HD-7000 and R-series, as well as the latest game consoles Xbox One and Playstation 4 application.
In addition, the APU combines several other important functions in it, which were formerly separately vorfand in the chipset on the motherboard, such as the memory controller with a native support for DDR3 memory up to 1866MHz clock. Here AMD now uses a heterogeneous system architecture, whereby graphics and processor cores working together more intensively. A feature of this technology is the new memory management called Huma that helps to provide shared access to the PC's RAM, which can be used equally by both parties. Both functional units can thus always exchange information with each other and operate independently.
Overall, this symbiotic chip offers thus all-round computing power for frugal claims - and all without a dedicated graphics card! With its maximum TDP of only 65 watts, it thus enables multimedia PCs in miniature and is ideal for use in ITX Cube or enclosures. If that is still too warm, which can, however, configure the power dissipation of its Kaveri APU with corresponding motherboard in the BIOS or UEFI free and the APU so limiting example, at 45 watts TDP.
Other highlights include e.g. support for multi-monitor Eyefinity velvet or Ultra-HD resolutions (4K). In addition, the integrated Universal Video Decoder (UVD) plays all imaginable forms of HD video material from liquid, without thereby burdening the CPU. AMD's revolutionary interface for hardware 3D calculations called Mantle relieves the processor of the APU and obsolete thanks to direct access to the graphics unit the most out of the Radeon graphics part with Graphics Core Next architecture out.
This boxed version of the processor include a matching CPU Cooler AMD supplied.
