AMD Dragon Range “Ryzen 7045” CPUs Come With Various Power Optimizations Delivering Up To 54% Higher Efficiency Versus Raptor Lake
AMD recently launched its Ryzen 7045 CPUs for enthusiast laptops codenamed Dragon Range and they come with some unique power optimizations.
During its latest Meet The Experts Webinar, AMD revealed how its Dragon Range Enthusiast CPU lineup is not only the fastest in application workloads but also in gaming. In various benchmarks, the company shows the flagship Ryzen 9 7945HX leading against Intel's top 13th Gen Raptor Lake chips including the Core i9-13980HX and Core i9-13950HX.
But what's even more important is how efficient the new AMD Ryzen 7045 Dragon Range family is. We have seen a few reviews where the Dragon Range CPUs just obliterate Intel in terms of power efficiency. This is achieved through implementing some mobile optimizations that aren't present on the desktop SKUs.
The first trick to achieve the level of efficiency that AMD's Dragon Range "Ryzen 7045" CPUs offer is to adopt Voltage Range tuning which let AMD engineers go a little bit aggressive with the voltages used by the Dragon Range chips are handled.
On desktops, you certainly have more margin when it comes to voltage though, on mobile, you have to be more careful (AMD's words) which means that laptops run cooler, consume lower power, and also run a bit faster. We have seen Ryzen 7000 CPU lineup for desktops offering similar or better performance when undervolted and the same is the case here. The end result is getting a higher frequency across a larger number of points on the voltage curve.
How do we make it even more efficient so that it can work in a notebook? One of the things that we do is voltage range tuning. So on desktops, we do what we call allow a lot of margin on voltage curve, there's voltage and frequency curve, and we probably use a little
