AMD Ryzen 5 5600F vs Intel Core Ultra 5 250K Plus Comparison

Head-to-Head Benchmarks

The benchmark data paints an unambiguous picture: the Intel Core Ultra 5 250K Plus wins all 11 recorded head-to-head tests. The largest margin appears in floating point math, where the Intel part scores 162,692 against the AMD Ryzen 5 5600F's 34,548, a delta of -78.8% from the AMD perspective. That is the widest gap in the entire comparison set. The smallest margin is in single-thread performance, where the Intel chip scores 4,757 versus 2,872, a -39.6% delta. Even in its closest contest, the AMD processor trails by nearly 40%.

Multi-threaded workloads show similar dominance. The Intel Core Ultra 5 250K Plus delivers 51,596 in the PassMark multi-thread test, while the Ryzen 5 5600F manages 19,236, a -62.7% gap. Data compression follows the same pattern: 568,721 for Intel versus 232,836 for AMD, a -59.1% difference. Encryption work favors Intel heavily as well, with 42,144 versus 13,839, a -67.2% delta.

The extended instructions test, which measures SIMD and other specialized instruction throughput, gives Intel a 44,565 score against AMD's 16,266, a -63.5% difference. Prime number finding, a test sensitive to integer throughput and branch handling, shows Intel at 486 versus AMD's 120, a -75.3% gap. Random string sorting, a memory-latency-sensitive workload, records 69,090 for Intel and 23,422 for AMD, a -66.1% delta.

Physics simulation, often a proxy for gaming-related CPU physics calculations, shows Intel at 3,494 versus AMD's 1,043, a -70.1% margin. Integer math, the foundation of general computing, gives Intel 125,091 against AMD's 59,339, a -52.6% gap. Across every recorded test, the Intel part holds a commanding lead, with no single benchmark where the AMD processor closes the gap below roughly 39%.

Architecture Differences

The two processors come from fundamentally different design generations. The AMD Ryzen 5 5600F uses the Zen 3 architecture, codenamed Vermeer, built on a 7 nm process at TSMC. It packs 4,150 million transistors into a 74 mm² die. The Intel Core Ultra 5 250K Plus uses Arrow Lake Refresh, built on a 3 nm process, also at TSMC, with 17,800 million transistors across a 243 mm² die. The node advantage alone explains a significant portion of the performance gap, as the Intel chip fits more than four times the transistor count into roughly three times the die area.

Core configuration differs sharply. The AMD part has 6 cores and 12 threads, relying on simultaneous multithreading to double thread count. The Intel part has 18 cores and 18 threads, with no hyperthreading; it simply offers three times the physical cores. Cache hierarchies reflect the architectural split. AMD uses 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3. Intel uses 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The Intel per-core L2 is six times larger, which helps with frequently accessed data.

Memory support diverges completely. The AMD processor runs DDR4 on a dual-channel bus with 51.2 GB/s of bandwidth. The Intel part runs DDR5 on a dual-channel bus with 115.2 GB/s, more than double the bandwidth. Both support ECC memory, a feature often reserved for workstation-class parts. PCIe connectivity also differs: AMD provides Gen 4 with 20 lanes, while Intel provides Gen 5 with 20 lanes, doubling the per-lane bandwidth for storage and GPU expansion.

Integrated graphics exist only on the Intel side, with an Arc Xe-LPG Graphics 64EU unit. The AMD part has no integrated graphics, requiring a discrete GPU for any display output. Clock speeds show the Intel chip running higher: a 4.20 GHz base and 5.30 GHz boost versus AMD's 3.00 GHz base and 4.00 GHz boost. Thermal design power reflects the performance disparity, with Intel rated at 125 W and AMD at 65 W.

Where Each One Wins

The Ryzen 5 5600F wins no recorded benchmark in this comparison. Its only advantages are structural rather than performance-based. It uses the AMD Socket AM4 platform, which supports DDR4 memory, allowing reuse of existing DDR4 modules. Its 65 W TDP is lower, which can simplify cooling requirements in compact builds. The smaller die size of 74 mm² and lower transistor count of 4,150 million indicate a less complex part that may be easier to manufacture, though the database does not record yield data.

The Intel Core Ultra 5 250K Plus wins every performance test. For single-threaded tasks, the 5.30 GHz boost clock and 3 nm process deliver a 39.6% advantage. For multi-threaded workloads, the 18 physical cores provide a 62.7% edge. The largest wins come in floating point math, where the combination of newer architecture, higher clocks, and wider SIMD units yields a 78.8% lead. Data encryption, a workload that benefits from dedicated instructions and high memory bandwidth, shows a 67.2% margin.

The Intel chip also carries integrated graphics, which means systems without a discrete GPU can still output video. Its PCIe Gen 5 support doubles the interface bandwidth for the fastest current SSDs and GPUs, provided the motherboard and peripherals support the standard. The 115.2 GB/s memory bandwidth is more than sufficient for DDR5 modules at standard speeds, and the larger per-core L2 cache helps with workloads that repeatedly access the same data sets.

Specification Differences

The two processors differ in every major specification category. The AMD Ryzen 5 5600F uses 6 cores and 12 threads; the Intel Core Ultra 5 250K Plus uses 18 cores and 18 threads. Base clocks are 3.00 GHz versus 4.20 GHz, and boost clocks are 4.00 GHz versus 5.30 GHz. TDP is 65 W versus 125 W. Sockets differ: AMD Socket AM4 versus Intel Socket 1851. Process nodes are 7 nm versus 3 nm, both from TSMC. Transistor counts are 4,150 million versus 17,800 million. Die sizes are 74 mm² versus 243 mm².

Cache configurations are not comparable on a per-core basis. AMD provides 64 KB L1 per core, 512 KB L2 per core, and 32 MB shared L3. Intel provides 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3. Memory support is DDR4 versus DDR5, with bandwidths of 51.2 GB/s versus 115.2 GB/s. PCIe generation is Gen 4 versus Gen 5, both with 20 CPU lanes. Integrated graphics are absent on AMD and present on Intel as Arc Xe-LPG Graphics 64EU. Release dates differ: September 15, 2025 for AMD and March 10, 2026 for Intel. The Intel part has a recorded launch MSRP of $199; the AMD part has no recorded MSRP in the database.

The Verdict

The data directs a clear choice. For any workload captured in the benchmark set, the Intel Core Ultra 5 250K Plus outperforms the AMD Ryzen 5 5600F by a wide margin. The smallest lead is 39.6% in single-thread performance; the largest is 78.8% in floating point math. The Intel chip also offers higher memory bandwidth, more physical cores, a newer process node, PCIe Gen 5, and integrated graphics. Its launch MSRP is recorded as $199, though the database does not list a comparable figure for the AMD part.

The AMD Ryzen 5 5600F retains relevance only for systems constrained by its 65 W TDP, DDR4 memory support, or AM4 socket compatibility. It is a functional desktop processor with a 85th percentile ranking among all CPUs, but its 36,945 average benchmark score sits far below the Intel part's 66,855 average. The Intel chip ranks in the 93rd percentile, a difference of 8 percentile points that reflects its position among all recorded processors.

The decision hinges on whether the platform advantages of AM4 and DDR4 outweigh a performance deficit that never drops below 39.6% in any tested metric. The benchmark record shows the Intel Core Ultra 5 250K Plus as the superior processor in every measured category, with the AMD part offering no performance counterpoint in the recorded data.
