Head-to-Head Benchmarks

The AMD Ryzen Threadripper 9970X dominates every recorded head-to-head benchmark, but the magnitude varies widely by workload type. In Passmark data compression, the AMD part scores 1757998 against 336177, a 422.9% advantage. That result aligns with the raw thread count and large L3 cache, which favor heavily parallel compression workloads.

In Passmark data encryption, the AMD part scores 86765 against 26345, a 229.3% advantage. Extended instructions show an even larger gap: 142342 against 27898, a 410.2% delta. Integer math produces the single largest delta at 459.9%, with the AMD part scoring 465378 and the Intel part scoring 83111. Floating-point math shows a 200.3% delta, with 309719 against 103128.

Prime number finding shows a smaller but still decisive gap. The AMD part scores 615 against 327, an 88.1% delta. Physics workloads record 6835 against 2895, a 136.1% delta. Random string sorting shows 191445 against 40990, a 367.1% delta.

The multithread benchmark puts the AMD part at 107399 against 33978, a 216.1% delta. That result sits between the extreme integer and encryption deltas and the smaller physics delta, indicating that the AMD part scales well across mixed parallel loads.

Single-thread performance is the closest contest. The AMD part scores 4530 against 4072, an 11.2% delta. The Intel part's Panther Lake architecture narrows the gap in single-threaded work, but it does not close it. The AMD part still leads in every recorded metric, and the single-thread result remains the only benchmark where the two processors are within a single-digit percentage of each other.

The benchmark data shows a clear pattern: the AMD Ryzen Threadripper 9970X leads by the smallest margin in single-threaded work and by the largest margins in integer math, extended instructions, and data compression. These results reflect the AMD part's 32 cores, 64 threads, and 128 MB of L3 cache, which allow it to maintain large advantages in parallel workloads.

The Verdict

The recorded data indicates that the AMD Ryzen Threadripper 9970X is the stronger processor in every benchmark category measured. The AMD part wins all 11 head-to-head comparisons, with deltas ranging from 11.2% in single-thread performance to 459.9% in integer math. The average benchmark score of 279778 places it in the 99th percentile of all CPUs, and its nearest rivals in the database are server-class Xeon and EPYC processors, which it trails by only 0.2% to 2.5%.

The Intel Core Ultra 7 356H, by contrast, records an average benchmark score of 41215 and sits in the 87th percentile. Its nearest rivals include the AMD Ryzen AI 5 PRO 440, the Intel Core Ultra 7 366H, the AMD Ryzen 9 5900X, and the Intel Core Ultra X7 358H, all within a 1% band. The Intel part's single-thread score of 4072 is the closest it comes to the AMD part, but it still trails by 11.2%.

The data supports a straightforward selection based on workload type. The AMD Ryzen Threadripper 9970X is the appropriate choice for parallel workloads that scale across many cores and threads, such as data compression, integer math, extended instructions, and multithreaded rendering. Its 350 W TDP, quad-channel memory, 128 MB of L3, and 80 PCIe Gen 5 lanes indicate a platform designed for maximum throughput in a desktop form factor.

The Intel Core Ultra 7 356H is the appropriate choice for mobile deployments where the 25 W TDP, integrated Intel Xe3 Graphics, and dual-channel LPDDR5X support matter more than raw parallel throughput. Its 16 cores and 16 threads deliver a fraction of the AMD part's multithreaded performance, but the power envelope and integrated graphics point to a different use case entirely.

The closest comparison between the two is single-thread performance, but even there the AMD part leads by 11.2%. For any application that relies on the benchmark categories recorded here, the AMD Ryzen Threadripper 9970X is the faster processor. The Intel Core Ultra 7 356H does not win a single recorded head-to-head comparison.
