AMD has recently announced its first Zen 4 APUs for its AM5 desktop platform at CES, and enthusiasts are already putting these budget-friendly processors to the test. The latest entry-level CPUs from AMD feature Zen 4 CPU cores and RDNA 3 graphics, designed for 1080p gaming without a discrete GPU. A professional overclocker has demonstrated the potential for significant performance gains by overclocking both the integrated GPU (iGPU) and system memory.
Skatterbencher, a renowned overclocker, has shared an extensive overclocking guide for the Radeon 780M integrated GPU found in the Ryzen 8700G. The guide showcases substantial headroom in the iGPU, with the overclocker achieving a remarkable 3,150MHz, up from the stock 2,881MHz. By also overclocking the CPU cores and pushing the memory to 8,000MHz, the overall performance saw a 37% boost, a feat that is quite exceptional for a desktop CPU without extreme cooling methods.
Skatterbencher’s testing involved various overclocking tools, including BIOS features and manual tuning, with each step’s impact reflected in benchmarks. While enabling AMD’s built-in overclocking in the BIOS (PBO and EXPO) yielded a 15% performance increase, overclocking the iGPU alone resulted in a 22% boost, demonstrating that significant gains can be achieved without overclocking all components. However, it’s important to note that such aggressive overclocking significantly increased power consumption, with the iGPU drawing up to 156W compared to its stock 50W, necessitating high-end cooling solutions.
While this level of overclocking may not be suitable for every user, it highlights the potential for substantial performance improvements in AMD’s budget-friendly CPUs. With the right expertise and cooling solutions, users can unleash impressive performance gains from these processors, opening up new possibilities for budget gaming setups.
