AMD Ryzen 9 7945HX 16-core laptop CPU trades places with Intel 13th Gen Core i9 HX series in Geekbench leak

AMD Dragon Range more than twice as fast as Rembrandt, compete with Intel’s flagship HX series

Twice the core count, twice the performance. 

The very first Ryzen 9 7945HX benchmark has been spotted over at Geekbench database. This SKU is part of AMD “Dragon Range” series with up to 16 Zen4 cores and 32 threads. There are just as many threads as Intel’s flagship 13th Gen Core-HX models, but the core count is lower (vs. 24).

AMD Ryzen 9 7945HX offers the full configuration with both CCDs featuring 8 cores. That’s twice as many cores as last gen Rembrandt silicon. AMD also increased max clock speeds and TDP for newest generation. The 7945HX goes up to 5.4 GHz with 55 watts, however the TDP may be configured up to 75 watts.

The AMD processor was tested on ASUS ROG Zephyrus Duo 16 laptop, the upcoming ultra-expensive dual-screen gaming notebook. It was equipped with a total of 32GB of DDR5 memory clocked at 4800 MT/s.

On average, the CPU scores 2061 and 18685 points in single and multi-core Geekbench tests. The highest score was 2127 points in single-core 19403 points in multi-core test. This score puts AMD processor on top of the single-core mobile CPU benchmark ranking and just about a few percent below in multi-core test compared to Intel 13th Gen Core i9-HX series.

Furthermore, the new Ryzen 9 for laptops is significantly faster than last-gen 8-core model. AMD Ryzen 9 6900HX Zen3+ processor with 8-cores offers just about half of the multi-core score compared to Ryzen 9 7945HX. What is also worth noting is that the AMD mobile CPU offers very similar performance to desktop 12-core CPU which has a higher default TDP (55W vs. 170W). However, Geekbench is a relatively short benchmark, so it definitely doesn’t tell the full story.
