AMD Ryzen Threadripper 9960X vs Intel Core Ultra 5 336H Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the AMD Ryzen Threadripper 9960X against the Intel Core Ultra 5 336H. This is a common situation when comparing processors from fundamentally different market segments: a 350 W desktop workstation part versus a 25 W mobile chip. However, the recorded data for the Intel Core Ultra 5 336H provides a baseline for interpretation. The Intel part achieves an average benchmark score of 34,485, placing it in the 84th percentile of all CPUs in the database. Its nearest rivals include the Intel Core i7-13700HX at 34,554 (0.2% ahead), the Intel Core i5-13450HX at 34,333 (0.4% behind), the AMD Ryzen 7 3700X at 34,260 (0.7% behind), and the AMD Ryzen AI 7 350 at 34,222 (0.8% behind). This places the Ultra 5 336H in a competitive mobile-class performance band, effectively trading blows with those established parts.

The Cinebench results for the Ultra 5 336H show a multi-core score of 23,991 in Cinebench R23 and 10,076 in Cinebench R20, with single-core scores of 3,387 and 1,422 respectively. In Cinebench R15, it records 2,418 multi-core and 341 single-core. PassMark results include a multithread score of 28,545, single-thread score of 4,013, integer math at 62,070, floating point math at 82,415, data compression at 280,340, data encryption at 21,291, extended instructions at 24,542, physics at 2,682, random string sorting at 34,402, and prime number finding at 299. Since the Threadripper 9960X has no recorded benchmark entries in the database, direct numerical comparison is impossible. The data confirms that the Ultra 5 336H is a capable mobile processor that outperforms or matches its nearest rivals within a narrow margin, but the absence of scores for the Threadripper means no delta can be calculated between the two.

Architecture Differences

The two processors are built on entirely different architectural foundations. The AMD Ryzen Threadripper 9960X uses the Zen 5 architecture with the Shimada Peak codename, part of the 9000 series and the Ryzen Threadripper generation. It is fabricated by TSMC on a 4 nm process node, with 33,260 million transistors spread across four 70.6 mm² dies. The Intel Core Ultra 5 336H uses the Panther Lake architecture, also its codename, from the Core Ultra Series 3 and Ultra 5 generation (Panther Lake-H). Intel fabricates this chip on its own 3 nm process node. Transistor count and die size are not recorded for the Intel part.

Core configuration differs dramatically. The Threadripper 9960X provides 24 cores and 48 threads with a base clock of 4.20 GHz and boost clock of 5.30 GHz. The Ultra 5 336H provides 16 cores and 16 threads, meaning no hyperthreading support, with a base clock of 1.90 GHz and boost clock of 4.60 GHz. Cache hierarchies are structured differently: the Threadripper has 64 KB L1 per core, 1 MB L2 per core, and 128 MB of L3 cache. The Ultra 5 336H has 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB of shared L3 cache. The Threadripper's L3 cache is 128 MB versus 18 MB, a substantial difference that favors heavily threaded workloads with large working sets.

Memory support also diverges. The Threadripper 9960X supports DDR5 in a quad-channel configuration with 204.8 GB/s of memory bandwidth and ECC memory enabled. The Ultra 5 336H supports DDR5 and LPDDR5X in a dual-channel configuration with 115.2 GB/s of memory bandwidth and no ECC support. PCI Express connectivity differs as well: the Threadripper provides Gen 5 with 80 lanes from the CPU, while the Ultra 5 provides Gen 5 with 12 lanes from the CPU. The Threadripper has no integrated graphics, while the Ultra 5 includes Intel Xe3 Graphics. The Threadripper uses AMD Socket sTR5 and has an unlocked multiplier; the Ultra 5 uses Intel BGA 2540 and is locked. Power envelopes are far apart: 350 W TDP for the Threadripper versus 25 W for the Ultra 5. The Threadripper launched on 2025-07-29 with a launch MSRP of $1499, while the Ultra 5 launched on 2026-01-04 with no recorded launch MSRP. The Threadripper targets the desktop market segment; the Ultra 5 targets mobile.

The Verdict

The recorded data shows two processors built for entirely different purposes. The AMD Ryzen Threadripper 9960X is a desktop workstation processor with 24 cores, 48 threads, 128 MB of L3 cache, quad-channel DDR5 with ECC, 80 PCIe Gen 5 lanes, and a 350 W TDP. Its 5.30 GHz boost clock, unlocked multiplier, and 4 nm TSMC process position it for high-throughput compute tasks that scale across many threads. The Intel Core Ultra 5 336H is a mobile processor with 16 cores, 16 threads, 18 MB of shared L3 cache, dual-channel memory, 12 PCIe Gen 5 lanes, integrated Intel Xe3 Graphics, and a 25 W TDP. Its 84th percentile ranking and average benchmark score of 34,485 place it in the same performance class as the Intel Core i7-13700HX, Intel Core i5-13450HX, AMD Ryzen 7 3700X, and AMD Ryzen AI 7 350, all within a 1% delta.

Since the Threadripper has no recorded benchmark scores, the database cannot confirm a direct performance advantage. What the data does confirm is the architectural intent: the Threadripper is designed for maximum multi-threaded throughput on a desktop platform with server-class memory bandwidth and PCIe lane count, while the Ultra 5 is designed for mobile efficiency with a 25 W envelope and integrated graphics. The Threadripper's 128 MB L3 cache and 204.8 GB/s memory bandwidth suggest workloads such as large dataset processing, compilation, and rendering. The Ultra 5's benchmark scores, particularly the Cinebench R23 multi-core result of 23,991 and PassMark multithread score of 28,545, indicate strong performance for a mobile chip, but its 16 threads and 18 MB cache place a hard ceiling on scaling.

Where Each One Wins

The AMD Ryzen Threadripper 9960X wins in every specification category that favors raw compute capacity. Its 24 cores and 48 threads double the thread count of the Ultra 5 336H. The 5.30 GHz boost clock exceeds the Ultra 5's 4.60 GHz. The 128 MB L3 cache is over seven times larger than the 18 MB shared cache on the Intel part. Quad-channel memory with 204.8 GB/s bandwidth nearly doubles the 115.2 GB/s of the dual-channel Ultra 5. The 80 PCIe Gen 5 lanes provide expansion headroom that the 12 lanes of the Intel chip cannot match. ECC memory support makes the Threadripper suitable for error-sensitive compute environments. The unlocked multiplier allows overclocking. The 350 W TDP, while high, signals sustained all-core performance capability. The 4 nm TSMC process with 33,260 million transistors indicates a much larger silicon footprint dedicated to compute.

The Intel Core Ultra 5 336H wins in efficiency and platform integration. Its 25 W TDP is a fraction of the Threadripper's 350 W, making it suitable for laptops and compact mobile devices. The 3 nm Intel process node is smaller than the 4 nm TSMC node. The integrated Intel Xe3 Graphics eliminates the need for a discrete GPU in basic display tasks. The 192 KB L1 cache per core and 2.5 MB L2 cache per core are larger than the Threadripper's per-core allocations, which can benefit latency-sensitive single-threaded operations. LPDDR5X memory support allows for power-efficient memory configurations. The BGA 2540 socket is a soldered mobile package, which is appropriate for thin-and-light designs. The 16 cores at 16 threads indicate a design prioritizing power efficiency over multi-threading. Its benchmark performance, ranked in the 84th percentile with an average score of 34,485, positions it competitively against the Intel Core i7-13700HX, Intel Core i5-13450HX, AMD Ryzen 7 3700X, and AMD Ryzen AI 7 350. The Threadripper 9960X, with no recorded benchmarks, cannot be placed in the same percentile ranking, but its desktop workstation classification and 350 W TDP clearly target sustained multi-threaded workloads rather than mobile efficiency. The data supports a straightforward split: the Threadripper for high-throughput desktop compute, the Ultra 5 for mobile systems where power draw and integrated graphics matter more than absolute core count.
