The upcoming AMD Ryzen 7040-series Phoenix processors for laptops based on the Zen 4 microarchitecture will be available in three distinct packages aimed at various types of laptops. Golden Pig Upgrade, a Chinese technology review channel, has published a review of the Ryzen 7 7840HS processor, which compares AMD’s FP8 and FP7/FP7r2 form factors (via VideoCardz).
The AMD Ryzen 7040-series CPUs will be available in both new FP8 and proven FP7 packages. The newer FP8 is noticeably larger than the previous FP7/FP7r2. Furthermore, the FP8 package is intended to support higher-performance interfaces such as AMD’s MIPI CSI, a high-speed interface protocol for transmitting video and images from camera to host. This package is better suited for devices that require more data throughput and advanced camera capabilities.
The FP7 package, on the other hand, is smaller and lighter. It has the same advanced features and performance as the FP8 package, but it is more compact, allowing manufacturers to create slimmer devices without sacrificing processing power. FP7/FP7r2 is a better fit for lightweight and portable devices in general.
In addition, some FP7 CPUs will be compatible with PCB designs from the Ryzen 6000 series. AMD will advise its partners to use different printed circuit boards with Zen 4-based products with FP8 and FP7/FP7r2 packages when it comes to PCBs.
Some AMD Ryzen 7040-series laptops will be using the Type 3 10-layer PTH (plated through-hole) PCBs, while others will use Type 4 HDI (high-density interconnect) PCBs.
PTH PCBs use through-hole mounting, have lower component density, and are less expensive, making them appropriate for simpler designs. Due to advanced fabrication techniques, HDI PCBs have higher component density and provide better electrical performance.
As a result, while they are ideal for miniaturised, high-performance electronic devices, they are more expensive to produce. Type 3 PCBs in AMD notebooks will support up to LPDDR5X-6400 memory, while Type 4 PCBs will support LPDDR5X-7500.
The AMD Ryzen 7040HS and the AMD Ryzen 7040H specifications are another intriguing aspect of AMD Ryzen 7040-series CPUs. In terms of TDP, they appear to be identical on paper. AMD’s Ryzen 6000H processors, on the other hand, are rated for up to 45W, while the Ryzen 6000HS is rated for up to 35W. Unfortunately, neither the Golden Pig Upgrade review nor AMD’s website explain the differences between the AMD Ryzen 7000HS and the Ryzen 7000H series, so we’re left perplexed.
The Ryzen 7 7840H with the Radeon 780M-badged RDNA3 integrated GPU is compared to the Ryzen 7735H (based on Rembrandt silicon with Zen 3 and RDNA 2) and two Intel Raptor Lake CPUs (13700H and 13500H). Although the latest Ryzen CPU boasts superior GPU performance, the improvement over the previous-generation RDNA2 iGPU is minor. Finally, the iGPU outperforms the discrete GeForce MX550 GPU and approaches the performance of GeForce GTX 1650 Max-Q designs.
