Renoir family processors feature up to 8 CPU cores compared to 4 cores of the previous generation mobile AMD CPUs.Ī 4800H will work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. This isn't the only noteworthy change however as Zen 2 architecture is leagues ahead of the outgoing Zen+ when it comes to single-core performance.
Ryzen 7 4800H is manufactured on the modern 7 nm TSMC process and in part thanks to this fact AMD promises an up to 2x higher performance-per-watt figure compared to Ryzen 3000 series mobile APUs. Thread-doubling SMT tech is enabled in this processor, allowing for up to 16 concurrent processing threads. The CPU also has 8 MB of 元 cache and a Vega series integrated GPU. The Ryzen features eight Zen 2 cores running at 2.9 GHz (base clock speed) to 4.2 GHz (Boost). The AMD Ryzen 7 4800H is a Renoir APU designed for larger, more powerful laptops with room for better termals. The R9 7845HX is rated at a TDP of 55 Watt and can be configured from 45 to 75 Watt (cTDP).ĪMD Ryzen 7 4800H ► remove from comparison The chip integrates 4x USB 3.2 Gen2 (10 Gbps) ports (no USB4), 28 PCIe 5.0 lanes (for GPU and SSDs) and a dual-channel DDR5-5200 memory controller. The Dragon Range series still uses a chiplet design with two CCD-clusters (each with 8 possible cores) in 5nm and an IO-die (including the memory controller and the Radeon 610M iGPU) in 6nm.
The performance of the R9 7845HX is significantly faster than the old top model Ryzen 9 6980HX (8 Zen 3 cores, 5 GHz max) thanks to the higher core count, improved architecture and higher clock speed. The 7845HX is the second-fastest mobile Ryzen CPU at launch and derived from the desktop Ryzen 9 7900X. The cores clock from 3 (base) up to 5.2 GHz (single core boost). It offers 12 of the 16 cores based on the Zen 4 architecture that supports hyperthreading (24 threads).
The AMD Ryzen 9 7845HX is a fast high-end laptop processor of the Dragon Range series. AMD Ryzen 9 7845HX ► remove from comparison
