Ryzen 9000 CPUs get “Curve Shaper” for optimal overclocking

According to the renowned overclocker 1usmus, the upcoming AMD Ryzen 9000 “Zen 5” CPUs come with a new overclocking function called Curve Shaper. This extension of the existing Curve Optimizer enables much finer control over the voltage-frequency curves (VFCurves) of the CPUs and thus promises more precise overclocking and improved performance.

The Curve Optimizer, which is already used in current Ryzen CPUs, automatically selects an optimal VC curve for the entire load and temperature range. However, this often leads to compromises, as the selected curve is not always ideal for all ranges.

Curve Shaper, however, addresses this limitation by allowing users to control the curve across the entire temperature range. This allows the VFCurve to be precisely adjusted to individual needs and the cooling system, which in combination with the new Zen 5 architecture, which promises a 16% IPC increase, can lead to significant performance gains.

1usmus has already published a detailed table of the Curve Shaper function, which defines various voltage and frequency values for different temperatures. This table can be used by experienced overclockers as a basis for fine-tuning the VFCurve of their Ryzen 9000 “Zen 5” processor.

Curve Shaper is just one of several exciting features that come with the AMD Ryzen 9000 “Zen 5” CPUs. Other highlights include:

Zen 5 core architecture, offering a phenomenal 16% IPC increase. Improved gaming and multi-threaded performance, ideal for demanding applications and games. Support for faster memory, enabling higher data transfer rates and faster access times.

The introduction of Curve Shaper in the AMD Ryzen 9000 “Zen 5” CPUs is a real novelty for enthusiasts and overclockers. The new feature allows for more precise and customized VFCurve adjustments, which can lead to significant performance improvements and optimized system stability. In combination with the other improvements to the Zen 5 architecture, the Ryzen 9000 CPUs promise a significant leap in performance for the next generation of computers.
