The AMD Ryzen 7 7840HS is an octa-core processor from the Phoenix series that is designed for high-end laptops. It offers exceptional performance and is based on the latest Zen 4 architecture, which provides better energy efficiency, improved instruction per clock (IPC), and higher clock speeds. With a base clock of 3.8 GHz and a single-core boost clock of 5.1 GHz, the Ryzen 7 7840HS is a highly capable processor that can handle demanding tasks with ease.
The chip has 8 cores and 16 threads, which is excellent for multi-tasking and running resource-intensive applications. It also includes 8 MB of L2 cache and 16 MB of L3 cache, which improves performance by reducing the need for data to be transferred between the processor and RAM. The CPU has a TDP (Thermal Design Power) of 35 watts, which is within the range of most high-end laptop processors.
The Phoenix series includes an RDNA 3 graphics card called Radeon 780M, which is a highly capable iGPU that can handle most modern games at decent frame rates. It has 12 CUs (compute units) and a clock speed of up to 2.7 GHz, making it faster than most other integrated graphics solutions. The processor also has a video engine that supports AV1 decoding and encoding, which is a new open-source video codec that offers better compression efficiency than previous codecs.
Another notable feature of the Ryzen 7 7840HS is the Xilinx FPGA-based XDNA AI accelerator, which is designed to handle artificial intelligence workloads. The AI accelerator is faster than the AI engine in the Apple M2 SOC, making it an attractive option for those who require high-performance AI processing capabilities.
The processor includes a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller, which provides support for faster and more energy-efficient memory. Additionally, the memory controller supports ECC (Error-Correcting Code) memory, which is useful for those who require high data integrity.
The connectivity features of the Ryzen 7 7840HS are also impressive. The processor supports USB 4 (40 Gbps) ports, which provide faster data transfer speeds than USB 3. Additionally, it has 20 PCIe 4.0 lanes, which can be used to connect high-speed storage devices and graphics cards.
The Phoenix series uses a single monolithic design, which is different from the chiplet design used in the 7045HX series. The monolithic design allows for better power efficiency, as it reduces the need for data to be transferred between the different chiplets.
The Ryzen 7 7840HS is manufactured using the 4nm process at TSMC, which is the latest and most advanced process node available. The 4nm process offers better power efficiency and performance than previous generations of manufacturing nodes, which makes it an ideal choice for high-end processors like the Ryzen 7 7840HS.
In terms of performance, the Ryzen 7 7840HS is a highly capable processor that can handle most tasks with ease. It is slightly slower than the fastest model in the Phoenix series, the Ryzen 9 7940HS, but the difference in performance is minimal. It also outperforms the older Ryzen 9 6980HX and Ryzen 9 6980HS processors.
In conclusion, the AMD Ryzen 7 7840HS is a highly capable processor that offers exceptional performance and energy efficiency. It is based on the latest Zen 4 architecture, which provides improved IPC and clock speeds, and includes an RDNA 3 graphics card, Xilinx FPGA-based XDNA AI accelerator, and fast memory support.
