AMD Ryzen Threadripper 9960X vs Intel Core Ultra 5 250KF Plus Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for only one of the two processors in this comparison. The Intel Core Ultra 5 250KF Plus has a full set of seventeen benchmark scores across Cinebench and Passmark tests, while the AMD Ryzen Threadripper 9960X has no benchmark entries listed. This makes a direct head-to-head comparison of measured scores impossible. What the data does allow is an assessment of the Intel part's performance profile and its position relative to other CPUs in the database, then a qualitative analysis of how the AMD part's specifications might translate into expected performance based on the architecture data available.

The Intel Core Ultra 5 250KF Plus posts a Cinebench R23 multicore score of 42718 and a single-core score of 6030. The Cinebench R20 results show 17941 for multicore and 2532 for single-core. The older Cinebench R15 test yields 4305 multicore and 607 single-core. These scores indicate a processor that scales reasonably well from single-threaded to multi-threaded workloads, with the multicore score approximately seven times the single-core score in R23, consistent with an 18-core, 18-thread configuration that relies on physical cores without hyperthreading.

Passmark results for the Intel part include a multithread score of 50146 and a single-thread score of 4698. The integer math test records 123030, floating point math records 159824, and extended instructions (SIMD) records 42880. Data compression scores 553155, while data encryption scores 41292. Random string sorting finishes at 67209, and the find prime numbers test produces 452. Physics simulation scores 3183. The floating point math result being roughly 30% higher than integer math suggests the architecture handles FP workloads efficiently, which matters for scientific computing and rendering tasks.

The Intel processor holds a percentile rank of 93 among all CPUs in the database, placing it in the upper tier of recorded processors. Its average benchmark score is 66159. The nearest rivals in the database are closely grouped: the Intel Core 9 273PQE scores 66099, which is 0.1% behind; the AMD Ryzen 9 7950X3D scores 65914, which is 0.4% behind; the Intel Core Ultra 5 250K Plus scores 66855, which is 1% ahead; and the AMD EPYC 4465P scores 66925, which is 1.1% ahead. This clustering shows the Core Ultra 5 250KF Plus sits in a competitive band where the top four neighboring processors are all within roughly 1% of each other in average score.

The AMD Ryzen Threadripper 9960X has no benchmark scores in the database, and its percentile rank is listed at 50 with an average score of zero. The nearest rivals field for the AMD part is empty. This means the database currently holds no measured performance data for the Threadripper, and any comparison must rely on architectural specification differences rather than recorded test results.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen Threadripper 9960X uses the Zen 5 architecture with the codename Shimada Peak, built on a 4 nm process at TSMC. The Intel Core Ultra 5 250KF Plus uses the Arrow Lake Refresh codename from the Core Ultra Series 2, built on a 3 nm process, also at TSMC. The smaller process node for Intel gives it a density advantage in principle, though the AMD part uses a chiplet design with four dies each measuring 70.6 mm², for a combined die area that differs substantially from Intel's monolithic 243 mm² die.

Transistor counts differ significantly. The AMD processor contains 33,260 million transistors across its four dies, while the Intel processor contains 17,800 million transistors on its single die. The AMD part's nearly double transistor count aligns with its larger core count and larger cache hierarchy.

Core and thread configurations diverge sharply. The AMD Threadripper 9960X provides 24 cores and 48 threads, using simultaneous multithreading to present two threads per core. The Intel Core Ultra 5 250KF Plus provides 18 cores and 18 threads, with no hyperthreading support. Both processors run at identical base clocks of 4.20 GHz and identical boost clocks of 5.30 GHz, so clock speed is not a differentiator.

Cache hierarchies reveal different strategies. The AMD part uses 64 KB of L1 cache per core and 1 MB of L2 cache per core, with a massive 128 MB of L3 cache shared across the chip. The Intel part uses 192 KB of L1 cache per core and 3 MB of L2 cache per core, but only 30 MB of shared L3 cache. The AMD L3 cache is more than four times larger, which typically benefits workloads with large working sets that can fit in cache. The Intel L2 cache is three times larger per core, which can help with per-core working sets.

Memory architecture differs as well. The AMD Threadripper 9960X supports quad-channel DDR5 memory with a theoretical bandwidth of 204.8 GB/s. The Intel Core Ultra 5 250KF Plus supports dual-channel DDR5 with 115.2 GB/s bandwidth. The AMD part offers nearly 78% more memory bandwidth, a factor that becomes important for memory-bound workloads such as large data processing and certain scientific simulations.

PCIe connectivity also differentiates the two. The AMD part provides 80 Gen 5 lanes from the CPU, while the Intel part provides 20 Gen 5 lanes. The AMD platform supports far more expansion devices at full bandwidth, which matters for multi-GPU configurations, high-speed storage arrays, and accelerator cards.

Both processors support ECC memory, both use DDR5, and both have no integrated graphics. Both have unlocked multipliers for overclocking. The AMD part uses socket sTR5, while the Intel part uses socket 1851. The AMD part carries a 350 W TDP, while the Intel part is rated at 125 W. The production status for both is listed as active.

The Verdict

The data in the database makes a definitive performance comparison impossible because only the Intel part has recorded benchmark scores. The Intel Core Ultra 5 250KF Plus is a measured performer sitting at the 93rd percentile of all CPUs, with an average score of 66159 and a tight cluster of rivals within 1.1%. The AMD Ryzen Threadripper 9960X has no measured scores, so its database profile is incomplete.

From the specification data alone, the AMD part appears designed for a different class of workload. Its 24 cores with 48 threads, 128 MB of L3 cache, quad-channel memory, and 80 PCIe lanes target multi-threaded, memory-hungry, expansion-heavy environments. The Intel part, with 18 physical cores, 30 MB of L3 cache, dual-channel memory, and 20 PCIe lanes, targets mainstream desktop workloads where single-thread performance and moderate multi-threading are sufficient.

The identical clock speeds suggest the two processors may have comparable single-thread performance, but the lack of measured data for the AMD part prevents confirmation. The Intel part's single-thread score of 4698 in Passmark and 6030 in Cinebench R23 places it in a competitive position, but whether the Zen 5 architecture in the Threadripper matches or exceeds those scores cannot be determined from the database.

The release dates differ substantially. The AMD part launched on 2025-07-29, while the Intel part launched on 2026-03-10. The launch MSRP for the AMD part is $1499, while the Intel part carries a launch MSRP of $184. The database does not provide enough measured data to judge whether the price difference corresponds to performance differences.
