AMD Ryzen Threadripper 9970X vs Intel Core Ultra 9 386H Comparison

Head-to-Head Benchmarks

The AMD Ryzen Threadripper 9970X dominates the Intel Core Ultra 9 386H across every recorded benchmark, winning all 11 head-to-head comparisons. The largest gap appears in integer math, where the Threadripper scores 465378 against the Core Ultra 9's 87284, a delta of 433.2%. Data compression shows a similar pattern, with the AMD part at 1757998 versus 352365, a 398.9% margin. Extended instructions follow closely at 388.5% (142342 vs 29138), and random string sorting lands at 354.4% (191445 vs 42135).

The multi-threaded PassMark result confirms the scale of the performance divide. The Threadripper 9970X posts 107399, while the Core Ultra 9 386H manages 35399, putting the AMD chip 203.4% ahead. Floating point math shows a 185.4% gap (309719 vs 108527), and physics simulation scores 6835 against 3028, a 125.7% advantage. Data encryption completes the sweep with a 219.6% lead, 86765 versus 27150.

The closest contest occurs in single-threaded performance, where the Threadripper 9970X scores 4530 and the Core Ultra 9 386H scores 4218, a modest 7.4% delta. This narrow gap indicates that architectural efficiency in the Intel mobile part nearly matches the AMD desktop flagship on a per-thread basis. Prime number finding shows an 80.4% margin (615 vs 341), which remains substantial but smaller than the other multi-threaded workloads.

The average benchmark scores reinforce the hierarchy. The Threadripper 9970X holds an average of 279778, placing it in the 99th percentile among all CPUs. The Core Ultra 9 386H averages 43210, good for the 88th percentile. The nearest rivals for the AMD part include the Intel Xeon 6780E at 280438 (0.2% higher) and the AMD EPYC 9565 at 285471 (2% higher). The Core Ultra 9 386H sits near the AMD Ryzen AI Max PRO 385 (43326, 0.3% higher) and the AMD Ryzen AI 9 465 (43431, 0.5% higher).

Architecture Differences

The two processors target entirely different market segments, and the silicon reflects that split. The AMD Ryzen Threadripper 9970X uses the Zen 5 architecture from the Shimada Peak codename, built on a 4 nm process at TSMC. It packs 32 cores and 64 threads. The Intel Core Ultra 9 386H uses the Panther Lake architecture, fabricated on Intel's 3 nm process, with 16 cores and 16 threads. Notably, the Intel part has no hyper-threading, so its thread count equals its core count.

Cache layouts differ sharply. The Threadripper 9970X provides 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of shared L3. The Core Ultra 9 386H offers 192 KB of L1 per core, 2.5 MB of L2 per core, and only 18 MB of shared L3. The AMD chip's L3 cache is over seven times larger, which directly supports its data-heavy workloads. Transistor count for the Threadripper is listed at 33,260 million across a die size of 4x 70.6 mm²; the Intel part has no recorded transistor or die size data.

Memory architecture also diverges. The Threadripper 9970X supports DDR5 over a quad-channel bus with 204.8 GB/s of bandwidth and ECC memory. The Core Ultra 9 386H supports DDR5 and LPDDR5X over a dual-channel bus with 115.2 GB/s and no ECC. PCIe connectivity favors the desktop part heavily: 80 Gen 5 lanes on the CPU versus 12 Gen 5 lanes on the mobile chip. Integrated graphics appear only on the Intel side, which carries Intel Xe3 Graphics; the Threadripper has none.

The AMD processor uses the AMD Socket sTR5 and has an unlocked multiplier. The Intel chip uses Intel BGA 2540, a soldered mobile socket, with a locked multiplier. The Threadripper 9970X launched on 2025-07-29 with a launch MSRP of $2499. The Core Ultra 9 386H launched on 2026-01-04 with no recorded launch MSRP. The Threadripper's TDP is 350 W, while the Core Ultra 9 386H is rated at 25 W, a 14x difference that explains the performance gap.

Where Each One Wins

The AMD Ryzen Threadripper 9970X wins every recorded workload category, but the size of each win tells a different story. For heavily parallel workloads, the Threadripper is decisively ahead. Data compression, integer math, extended instructions, and random string sorting all show deltas above 350%, reflecting the benefit of 32 cores, 64 threads, and massive L3 cache. These tasks scale with core count and memory bandwidth, and the Threadripper has both in abundance.

The Core Ultra 9 386H finds its narrowest gap in single-threaded performance, trailing by only 7.4%. That result suggests the Panther Lake architecture, built on Intel's 3 nm node, delivers strong per-core efficiency. For mobile workloads where power draw is constrained, the 25 W TDP makes the Core Ultra 9 386H functional in ways the 350 W Threadripper cannot match. The Intel chip also brings integrated Xe3 graphics, a feature entirely absent from the AMD part, and supports LPDDR5X memory for low-power designs.

The prime number benchmark shows a moderate 80.4% gap, smaller than the multi-threaded average. This indicates that the Core Ultra 9 386H's per-core integer throughput is comparatively respectable. Physics simulation and floating point math show gaps of 125.7% and 185.4%, which are large but not as extreme as the data-heavy workloads. The Threadripper's wins are largest where cache capacity and memory bandwidth matter most, and smallest where single-core speed is the limiting factor.

Specification Differences

The processors differ across nearly every core specification. The Threadripper 9970X has 32 cores and 64 threads; the Core Ultra 9 386H has 16 cores and 16 threads. Base clocks are 4.00 GHz versus 2.10 GHz, and boost clocks are 5.40 GHz versus 4.90 GHz. The TDP rating is 350 W for the AMD part and 25 W for the Intel part. The Threadripper uses AMD Socket sTR5, while the Intel chip uses Intel BGA 2540.

Cache specifications diverge completely. The Threadripper provides 64 KB L1 per core, 1 MB L2 per core, and 128 MB L3. The Core Ultra 9 offers 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB L3. Memory support shows DDR5 for the AMD side versus DDR5 and LPDDR5X for the Intel side. Memory channels are quad for AMD, dual for Intel, and bandwidth is 204.8 GB/s versus 115.2 GB/s. ECC is supported on the Threadripper but not on the Core Ultra 9.

PCIe lane counts differ by a factor of more than six: 80 Gen 5 lanes on the Threadripper versus 12 Gen 5 lanes on the Core Ultra 9. Integrated graphics exist only on the Intel chip. The process node is 4 nm at TSMC for AMD and 3 nm at Intel for the mobile part. The Threadripper has an unlocked multiplier; the Core Ultra 9 does not. The Threadripper's part number is 100-000001594, while the Intel part is SA4R5Q9EH. The Intel chip has no recorded launch MSRP.
