AMD Ryzen Threadripper 9970X vs Intel Core Ultra 9 290HX Plus Comparison

The Verdict

The recorded data separates these two processors into entirely different performance classes, despite both carrying flagship positioning in their respective segments. The AMD Ryzen Threadripper 9970X wins 9 of 11 head-to-head benchmarks, while the Intel Core Ultra 9 290HX Plus takes only 2. The Threadripper delivers massive multi-threaded superiority, with the largest single margin reaching 182.3% ahead in integer math. Its average benchmark score of 279778 places it in the 99th percentile of all CPUs, while the Intel part scores 79574 on average, sitting in the 95th percentile.

The Intel Core Ultra 9 290HX Plus claims victory only in single-threaded tests, scoring 4951 versus 4530, a margin of 8.5%. That advantage is real but narrow in context. The Threadripper counters with a 4.00 GHz base clock and 5.40 GHz boost, while Intel runs 2.70 GHz base and 5.50 GHz boost. The data suggests the desktop Threadripper exists for sustained heavy workloads, while the mobile Intel chip prioritizes single-core responsiveness within a 55 W envelope. The Threadripper carries a 350 W TDP, a 295 W gap that reflects its desktop sTR5 platform and quad-channel memory design.

For users who need maximum parallel throughput across 32 cores and 64 threads, the Threadripper 9970X is the clear choice. For workloads that depend on single-thread latency and low power draw in a mobile form factor, the Intel Core Ultra 9 290HX Plus holds the edge. The data does not support using the Intel chip for heavily threaded tasks, where it trails by 80.7% in multithread performance and 101.8% in physics calculations.

Architecture Differences

The AMD Ryzen Threadripper 9970X belongs to the 9000 series and uses the Zen 5 architecture under the codename Shimada Peak. It is built on TSMC's 4 nm process node with 33,260 million transistors spread across a 4x 70.6 mm² die configuration. The Intel Core Ultra 9 290HX Plus comes from the Core Ultra Series 2, codenamed Arrow Lake-HX Refresh, and uses a 3 nm TSMC process with 17,800 million transistors on a single 243 mm² die. The node difference favors Intel in density, but the Threadripper compensates with a multi-die layout that accommodates far more cores.

Cache hierarchies diverge significantly. The Threadripper allocates 64 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Intel chip provides 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The Threadripper's total L3 cache is more than three times larger, which helps explain its dominance in data compression and random string sorting where large working sets benefit from on-die storage. Intel's larger per-core L1 and L2 caches support its single-thread advantage.

The Threadripper integrates no graphics, requiring a discrete GPU for display output. The Intel chip includes Arc Xe-LPG Graphics with 64 execution units, making it suitable for systems without a dedicated graphics card. The Threadripper uses AMD Socket sTR5, while the Intel chip uses BGA 2114, a soldered mobile socket. Both processors have unlocked multipliers, though the Threadripper's desktop platform offers more overclocking headroom in practice.

The Threadripper's 128 MB L3 and 32 cores make it a data-center-class part aimed at servers and workstations. The Intel chip's 36 MB L3 and 24 cores target high-end mobile workstations. The production status for both is active, with the Threadripper released on 2025-07-29 and the Intel chip released on 2026-03-16.

Specification Differences

The core count differs by 8 cores, with the Threadripper at 32 and the Intel chip at 24. Thread counts differ by 40, with the Threadripper at 64 threads versus the Intel chip's 24. Base clocks measure 4.00 GHz for AMD and 2.70 GHz for Intel, a 1.30 GHz gap. Boost clocks are closer, 5.40 GHz versus 5.50 GHz, giving Intel a 0.10 GHz edge at the top end.

TDP ratings represent the largest specification gap besides cores. The Threadripper draws 350 W, while the Intel chip draws 55 W. This 295 W difference reflects the desktop versus mobile design philosophy. The Threadripper uses quad-channel memory for 204.8 GB/s bandwidth, while the Intel chip uses dual-channel for 102.4 GB/s, exactly half the bandwidth.

PCIe lane counts also halve: 80 lanes on the Threadripper versus 20 lanes on the Intel chip, both Gen 5. The Threadripper has no integrated graphics; the Intel chip includes Arc Xe-LPG Graphics with 64 EU. Socket types differ entirely, sTR5 versus BGA 2114, meaning no platform compatibility between the two.

The Threadripper carries a launch MSRP of $2499. The Intel chip has no listed launch MSRP in the database. Release dates differ by roughly eight months, with the Threadripper arriving first.

Head-to-Head Benchmarks

The Threadripper wins every multi-threaded test in the head-to-head set, often by substantial margins. Data compression shows the largest absolute gap: 1757998 versus 658724, a 166.9% advantage. This test benefits from the Threadripper's 128 MB L3 cache and 64 threads. Extended instructions follow at 177.5% (142342 versus 51290), and integer math leads by 182.3% (465378 versus 164839), the largest percentage margin in the entire comparison.

Floating-point math favors the Threadripper by 53.5% (309719 versus 201773), a smaller gap than integer math but still decisive. Random string sorting shows a 138.3% advantage (191445 versus 80327), again leveraging the large cache and thread count. Data encryption comes in at 73.5% (86765 versus 50008), while find prime numbers shows the narrowest Threadripper win at 18.5% (615 versus 519).

Multithread performance confirms the overall trend: 107399 versus 59439, an 80.7% lead. Physics calculations amplify this to 101.8% (6835 versus 3387). The Intel chip's only wins come in single-thread tests, where it scores 4951 against 4530, an 8.5% margin. This result appears twice in the data, once as passmark_single_thread and once as passmark_singlethread, with identical scores.

The average benchmark scores contextualize these wins. The Threadripper's 279778 average sits within 0.2% of the Intel Xeon 6780E (280438) and 2% of the AMD EPYC 9565 (285471). The Intel chip's 79574 average lands 0.3% above the Intel Core i9-14900KF (79371) and 0.6% above the Intel Core i9-14900K (79097). These rival comparisons show both parts performing at the top of their respective classes.

Where Each One Wins

The Threadripper 9970X dominates in every throughput-oriented benchmark. Its 32 cores and 64 threads, combined with 128 MB of L3 cache and 204.8 GB/s memory bandwidth, make it the choice for workloads that scale with parallel execution. Data compression, encryption, extended instruction sets, integer and floating-point math, random string sorting, multithread, and physics all favor AMD by margins ranging from 18.5% to 182.3%. The 80 PCIe Gen 5 lanes also support large multi-GPU configurations, which the data implies through the lane count rather than direct benchmarks.

The Intel Core Ultra 9 290HX Plus wins only in single-threaded performance, where its 5.50 GHz boost clock and larger per-core L1 and L2 caches deliver a 8.5% edge. This makes it suitable for applications that primarily depend on single-core responsiveness, such as interactive development or lightly threaded legacy software. Its 55 W TDP and integrated Arc Xe-LPG Graphics with 64 EU also position it for mobile systems where power draw and space constraints matter. The dual-channel memory and 20 PCIe lanes limit expansion compared to the Threadripper, but the data does not show these constraints affecting its single-thread victories.

The 9 wins for AMD versus 2 wins for Intel in the head-to-head set make the overall performance hierarchy clear. The Threadripper's 99th percentile standing versus the Intel chip's 95th percentile confirms that the desktop part operates in a higher performance tier. Users requiring maximum parallel compute should select the Threadripper; users prioritizing single-thread speed and low power consumption in a mobile form factor should select the Intel chip. The data offers no scenario where the Intel chip outperforms the Threadripper in multi-threaded work, and no scenario where the Threadripper outperforms Intel in single-thread tests.
