The first benchmarks of Intel’s 13th Gen Raptor Lake-HX mobile flagship have surfaced. Leveraging 8 Raptor Cove “P” cores and 16 Gracemont “E” cores, it will go up against AMD’s Ryzen 9 7945HX, featuring sixteen Zen 4 cores. Now, at the moment, the PassMark database doesn’t have any runs of the 7945HX, so we’ll take the next fastest Dragon Range SKU, the Ryzen 9 7845HX. Like its elder sibling, it consists of two CCDs and an IOD, except a few cores on the secondary compute die are disabled, resulting in 12 physical cores.
The Ryzen 9 7945HX is the second fastest Dragon Range APU with 12 cores and 24 threads, backed by 76MB of L3 cache. The priority cores have a peak boost clock of up to 5.2GHz, up from their base frequency of just 3GHz. The Core i9-13980HX, on the other hand, boosts up to 5.6GHz on the performance cores and 4GHz on the efficiency cores. The CPU features 36MB of L3 cache and operates at a base TDP of 55W with a 157W boost TDP.
The Ryzen 9 7845HX has a base power draw of 45W and a peak power consumption of 75W, less than half as much as its Raptor Lake-HX rival. Despite the massive power deficit and the lower core count on the 7845HX, the Core i9-13980HX is just about 12% faster in the multi-threaded benchmark on average.
The Ryzen 9 7845HX beats the Core i9-13980HX in prime number math, physics, and extended instructions (AVX512?). In fact, the Raptor Lake-HX flagship is over 50% faster than the Dragon Range part in the Prime Number benchmark. Meanwhile, the former is 20% and 40% faster in the integer and floating point tests, respectively.
The single-core cores are closer, with a delta of just 492 MOps/Sec between the two. That said, the added core counts, higher clocks, and higher power envelope of the Ryzen 9 7945HX should level the scores of the two sides or at least bring them within single percentage figures of now another.
