AMD Ryzen 9 7845HX vs Intel Core i7-13700K Comparison

The Intel Core i7-13700K and AMD Ryzen 9 7845HX are both 24-thread processors occupying the 89th percentile of all CPUs, yet they are built for entirely different platforms. The data shows the Intel part, a desktop Raptor Lake-S chip, decisively outpaces the AMD mobile Dragon Range processor in the majority of head-to-head benchmarks, winning 19 of 23 tests. While the Ryzen 9 7845HX posts a higher average benchmark score than the Intel Xeon w3-2535 (46654 vs 46653, a 0% delta), the i7-13700K leads the 7845HX by 0.5% in average score (46881 vs 46654). This matchup is less about overall parity and more about where each chip’s architectural strengths manifest.

Head-to-Head Benchmarks

The Intel Core i7-13700K’s dominance is most pronounced in multi-threaded and single-threaded synthetic workloads. In Geekbench multicore, the Intel part scores 19429 against the AMD’s 16633, a 16.8% advantage. The gap widens in Cinebench R23 multicore, where Intel’s 30745 score beats AMD’s 26876 by 14.4%. Similarly, in 3DMark’s 16-thread test, Intel leads 10717 to 10068 (6.4%), and in the max-thread variant, the margin grows to 11.7% (12412 vs 11108). The pattern is consistent: Intel’s higher core count of 16 versus AMD’s 12, combined with a 5.40 GHz boost clock versus 5.20 GHz, translates into substantial throughput advantages.

Single-thread performance also favors Intel, though by a narrower margin. In Cinebench R23 single-core, the i7-13700K scores 2116 versus 1852 for the 7845HX, a 14.3% lead. Geekbench single-core shows a 5.9% Intel advantage (2529 vs 2389), and 3DMark single-thread shows 10.8% (1136 vs 1025). PassMark single-thread reinforces this, with Intel at 4333 and AMD at 3935 (10.1% lead). The Intel chip’s 3.40 GHz base clock, higher than AMD’s 3.00 GHz, helps establish this consistent single-thread superiority.

The AMD Ryzen 9 7845HX wins four tests, and they reveal the Zen 4 architecture’s specific strengths. The most dramatic win is in PassMark find prime numbers, where AMD scores 329 against Intel’s 191 — a 41.9% advantage. This is a massive margin, indicating the AMD chip’s integer-heavy computation efficiency. AMD also wins PassMark extended instructions (41020 vs 36625, a 10.7% lead), a test that leverages AVX-512-style workloads. In PassMark integer math, the 7845HX edges out Intel 155118 to 154446, a marginal 0.4% win, and in random string sorting, AMD leads 63223 to 62670 (0.9%). These wins are concentrated in specialized instruction paths rather than general-purpose throughput.

Other notable Intel wins include PassMark floating point math (114867 vs 94287, a 21.8% lead), 3DMark 4-thread (4469 vs 3807, 17.4%), and 3DMark 8-thread (8193 vs 7140, 14.7%). The Intel part also leads in Cinebench R15 multicore (4507.5 vs 4320, 4.3%) and PassMark multithread (45887 vs 45010, 1.9%). The data is unambiguous: the i7-13700K is the faster processor in nearly every scenario tested.

The Verdict

The data points to a clear winner for raw performance: the Intel Core i7-13700K wins 19 of 23 head-to-head benchmarks, including all major multi-threaded and single-threaded tests. Its 16.8% lead in Geekbench multicore, 14.4% lead in Cinebench R23 multicore, and 21.8% lead in PassMark floating point math demonstrate broad superiority. The Intel part also edges out the AMD chip in average benchmark score (46881 vs 46654, 0.5%). For anyone building a desktop system where maximum throughput is the priority, the i7-13700K is the better choice based on this data.

However, the AMD Ryzen 9 7845HX is not without merit. Its 41.9% win in PassMark find prime numbers and 10.7% win in extended instructions show that for specialized integer and extended instruction workloads, the Zen 4 architecture is significantly more efficient. The 7845HX also has a much lower TDP of 55 W versus Intel’s 125 W, and it is a mobile part, making it suitable for laptops where power draw and thermal output are critical. The data shows this is a desktop versus mobile comparison; the AMD chip’s wins are narrow except for the prime number test, while Intel’s wins are often double-digit percentages.

Where Each One Wins

The Intel Core i7-13700K wins in nearly all general-purpose computing scenarios. It is the pick for multi-threaded productivity, as evidenced by its 14.4% lead in Cinebench R23 multicore and 16.8% lead in Geekbench multicore. It also excels in single-threaded responsiveness, with 14.3% and 10.1% leads in Cinebench R23 single-core and PassMark single-thread, respectively. Physics simulations favor Intel by 15.8% (2716 vs 2346 in PassMark physics), and floating-point math is a 21.8% win for Intel. Data compression also goes to Intel by 9.5% (595292 vs 543539).

The AMD Ryzen 9 7845HX wins in four specific areas. For prime number finding, the AMD chip is overwhelmingly faster (329 vs 191, a 41.9% margin), suggesting a use case in mathematical or number-theoretic workloads. Extended instruction sets are another AMD strength, with a 10.7% lead (41020 vs 36625), indicating better AVX-512-style performance. Integer math is a narrow 0.4% win for AMD (155118 vs 154446), and random string sorting is a 0.9% win (63223 vs 62670). These wins, while few, point to specialized computational tasks where the Zen 4 architecture’s design provides a measurable advantage. For everything else, the Intel Core i7-13700K is the superior processor according to the benchmark data.
