This efficient fusion of CPU and GPU is called the Accelerated Processing Unit (APU) and benefits in a special way from the direct connection of the individual components. The AMD A12-9800E Quadcore is at the forefront of the Bristol Ridge APU generation, which entered the desktop market in the summer of 2017, and is relying on heavily reworked Excavator modules and a powerful graphics unit with Graphics Core Next v3 architecture.
AMD Bristol Ridge APU
The AMD A12-9800E 3.1 GHz 4-core processor at a glance:
4 cores (2 Excavator modules) with only 35 watts TDP
Basistact of 3.1 GHz & 3.8 GHz Turbo + 2 MB of L2 cache
Free multiplier for manual overclocking (unlocked CPU)
X86-64 (64-bit processor AMD64) & AMD-V virtualization
Integrated AMD Radeon R7 graphics unit with GCN v3 architecture
GPU features: AMD FreeSync, DirectX 12, Vulkan & Eyefinity
28-Nanometer Transistors (Diffused in Germany)
AVX2 instruction set extension for complex vector calculations
AES for reliable data encryption
Modern AM4 platform with extensive features
Supports energy-efficient DDR4 RAM (dual-channel)
AMD Boxed CPU cooler included!
The chip, produced in 28 nm, already clocks at 3.100 MHz in the basic stage and can increase the clock speed of individual cores to up to 3,800 MHz via TurboCore 3.0 with a corresponding load. Thanks to an open multiplier (unlocked CPU), the APU can be easily overclocked, but this is accompanied by the loss of the manufacturing guarantee. In addition, the chip is packed with a variety of modern features, including AES encryption, AMD-V virtualization technology, and SSE and AVX2 command set expansions.
Integrated AMD Radeon R7 graphics unit with GCN V3 architecture
The graphics unit in the form of an integrated Radeon chip of the R7 series has 512 shader cores with 900 MHz GPU clock. The graphic part of the APU team gained almost half of the chip area and has gained a lot of computing power compared to its predecessors. Not least, the Radeon R7 graphics benefit from the much faster DDR4 memory of the AMD socket AM4 platform. The underlying chip architecture is called Graphics Core Next (GCN) and is used in the dedicated Radeon R and Series Radeon graphics cards, as well as in the latest game consoles Xbox One and Playstation 4.
Overall, this symbiotic chip offers powerful computing power for demanding gaming demands - without the need for a dedicated graphics card! With a TDP of only 35 watts, the APU makes multimedia and entry-level gaming PCs possible in the smallest format. It is also predestined for use in Mini-ITX or Cube housings. Further highlights are e.g. (4K) or AMD's FreeSync and TrueAudio, as well as the low-level APIs Mantle, Vulkan, and DirectX12. In addition, the integrated universal video decoder (UVD) and the video code engine (VCE) play off all imaginable formats of HD video material without affecting the CPU.
High-tech platform AM4 with lush features
AMD Logo Mainboards with the AM4 socket offer state-of-the-art interfaces and serve as a platform for AMD Ryzen CPUs as well as AMD Raven Ridge and AMD Bristol Ridge APUs. The Bristol Ridge APU itself has two SATA 6G data channels for traditional SATA SSDs and two dedicated PCI Express 3.0 lanes to support modern PCI Express SSDs in M.2 or U.2 formats Developed NVM-Express protocol (NVMe for short).
A further 8 PCIe 3.0 lines provide more than enough bandwidth for alternative gaming graphics cards or other expansion cards. Additional data ports and PCIe lanes for additional volumes, add-on cards, and peripherals are provided separately, depending on the motherboard chipset. The AM4 platform also brings modern external device connections such as USB 3.1 Gen 2 with Type A and / or Type C connectors and high data transmission rates of up to 10 Gbit / s. AM4 motherboards also support fast, energy-efficient DDR4 memory in dual-channel mode via the CPU's built-in memory controller.
Notes: This is a boxed version including AMD CPU cooler. An AM4 motherboard is required to use an AMD Bristol Ridge or Raven Ridge APU.
