AMD’s upcoming Ryzen 7040-series Phoenix processors for laptops primarily based on the Zen 4 microarchitecture will are available in three totally different packages aimed toward several types of laptops. Chinese language expertise assessment channel Golden Pig Improve has revealed a assessment of the Ryzen 7 7840HS processor that, amongst different issues, compares AMD’s FP8 and FP7/FP7r2 kind elements (by way of VideoCardz).
AMD’s Ryzen 7040-series CPUs will likely be accessible in all-new FP8 in addition to in FP7r2 and confirmed FP7 packages. The newer FP8 is noticeably bigger than FP7/FP7r2. As well as, the FP8 package deal is designed to help higher-performance interfaces, together with, amongst different issues, AMD’s MIPI CSI, a high-speed interface protocol for transmitting video and pictures from digital camera to host. This package deal is extra appropriate for gadgets requiring greater information throughput and superior digital camera capabilities.
Against this, the FP7 package deal is smaller and lighter. It has the identical superior options or efficiency because the FP8 package deal however gives a extra compact answer for producers seeking to construct slimmer gadgets with out compromising processing energy. Basically, FP7/FP7r2 is a greater match for light-weight and transportable gadgets. Additionally, some FP7 CPUs will likely be appropriate with Ryzen 6000-series PCB designs. Concerning PCBs, AMD will advise its companions to make use of totally different printed circuit boards with Zen 4-based merchandise with FP8 and FP7/FP7r2 packages. For instance, some next-generation AMD Ryzen 7040-series laptops will depend on Type3 10-layer PTH (plated through-hole) PCBs, whereas others will use Sort 4 HDI (high-density interconnect) PCBs. PTH PCBs use through-hole mounting, have decrease part density, and are more cost effective, making them appropriate for much less advanced designs.
Against this, HDI PCBs have greater part density and supply higher electrical efficiency as a consequence of superior fabrication methods. In consequence, they are perfect for miniaturized, high-performance digital gadgets however are typically dearer to fabricate. Within the case of AMD’s notebooks, Sort 3 PCBs will help as much as LPDDR5X-6400 reminiscence, whereas Sort 4 PCBs will allow LPDDR5X-7500.
One other attention-grabbing side of AMD’s 7040-series CPUs is the Ryzen 7040HS and 7040H specs. On paper, they seem like equivalent when it comes to TDP. Nonetheless, AMD’s Ryzen 6000H processors are rated for as much as 45W, whereas Ryzen 6000HS is rated for as much as 35W. Sadly, neither the Golden Pig Improve assessment nor AMD’s web site clarifies the variations between the 7000HS and 7000H sequence, leaving us puzzled.
The assessment compares the Ryzen 7 7840H, that includes the Radeon 780M-badged RDNA3 built-in GPU, to the Ryzen 7735H (primarily based on the Rembrandt silicon with Zen 3 and RDNA 2) and two Intel Raptor Lake CPUs (13700H and 13500H). Though the most recent Ryzen CPU boasts superior GPU efficiency, the improve from the previous-gen RDNA2 iGPU is just not substantial. In the end, the iGPU outperforms the GeForce MX550 discrete GPU and approaches the efficiency of the GeForce GTX 1650 Max-Q designs.
