Ryzen 7 4800H features the Radeon RX Vega 7, a 7 CU integrated graphics adapter running at up to 1,600 MHz. The average 4800H in our database trades blows with Intel Core i7-11850H and Core i7-11800H, rendering the Ryzen a great option for quality gaming laptops as well as high-performance mini-PCs. Please go to our Renoir processor family hub for more information on these CPUs. The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. The important difference between desktop Ryzen 4000 and mobile Ryzen 4000 processors is that the latter do not have PCI-Express 4.0 support, meaning those blazing-fast NVMe SSDs will be limited to a throughput of 3.9 GB/s. 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. Its an incredibly useful tool for a ryzen laptop owner that has some semblance of common sense.AMD Ryzen 7 4800H ► remove from comparison Mine though tops out at 72c max when under full cpu/gpu stress so it's entirely capable of managing much more than the stock 12w power limit imposed from the factory (lenovo v155). Obviously theres room for abuse and I await the 'I killed my laptop' posts when people overdo it on laptops with poor thermal design. I have a £350 laptop that can actually game even though that's not what I bought it for. I have a 3500u laptop with a crippled 12w power limit, manually getting it upto 25w increases performance dramatically. Its been available awhile but needed manual interaction with no easy frontend interface. I think the tool is mainly aimed at laptops with severely locked down power limits. Precision boost overdrive in almost all cases seems to offer better gains than what you'll see from manually overclocking or using any kind of automatic utility. You are better off simply running at the default precision boost profile or if you have good enough cooling, using PBO/PBO2.
