AMD Ryzen 9 7845HX “Dragon Range” 12-Core Reference Laptop CPU, Faster Than Intel 12900K

AMD’s Ryzen 9 7845HX “Dragon Range” CPU with 12 Zen 4 cores was tested in the Geekbench benchmark and shows incredible performance for a laptop chip running at a TDP range of 55W.

The AMD Ryzen 9 7845HX 12-core Dragon Range CPU sits ahead of the Intel Core i9-12900K in a 55W TDP range

The AMD Ryzen 9 7845HX CPU is a high-end Dragon Range SKU that features the Zen 4 architecture and brings a large number of cores and a larger cache to the mobile platform. The chips are aimed at the enthusiast segment and as such TDPs range from 45W and beyond 75W. Now this chip has been tested in the Geekbench benchmark. Now that we’ve seen detailed benchmark tests of the AMD Ryzen 9 7945HX and Ryzen 7 7745HX CPUs, it’s time for us to see what the 12-core chip can handle against other chips.

AMD Ryzen 9 7845HX Dragon Range CPU was tested inside MECHREVO Jiaolong Series MRID6-23 Laptop, which is an Asian laptop manufacturer. The laptop comes with 32GB of DDR5-4800 memory and should also house a nice NVIDIA RTX 40-series discrete GPU, although the exact model hasn’t been mentioned.

So, in terms of performance, the AMD Ryzen 9 7845HX Dragon Range CPU scored 2697 points in single-core tests and 15039 points in multi-core tests within Geekbench 6. If we compare these performance numbers with the Intel Core i9 -12900K, we would see the Dragon Range chip being on par in multi-threaded performance and 6% faster in single-threaded performance with clocks up to 5.2GHz. What’s more impressive is the fact that the Core i9-12900K can consume up to 250W of power while the Dragon Range chip consumes around 50-60W of power when running similar multi-threaded tests.








The CPU also outperforms the Intel Core i7-13700HX, which scores around 2,450 points in single-core tests and 14,200 points in multi-threaded tests on the same benchmark with 16 cores. The only thing that remains to be seen is whether AMD can offer its Dragon Range line, including the Ryzen 9 7845HX, in decent numbers.

In the last two generations, AMD has had supply problems in the notebook CPU segment that allowed Intel to grab market share. AMD has great products but they should really work hard to fix the supply constraints in the laptop segment as the demand for their laptop chips will be overwhelming considering the performance efficiency and value their chips offer.
