AMD Ryzen 5 9500F vs Intel Core Ultra 5 250K Plus Comparison

Where Each One Wins

The recorded data paints a one-sided picture in the head-to-head benchmark suite. The Intel Core Ultra 5 250K Plus wins all 11 recorded comparisons against the AMD Ryzen 5 9500F. There is no benchmark category in the database where the AMD part takes the lead. That said, the margin of victory is not uniform across workloads, and the shape of those margins reveals where each processor holds its relative strengths.

The Intel chip's largest advantage appears in floating-point math, where it scores 162,692 against AMD's 56,570, a delta of 65.2% in Intel's favor. That is the single biggest gap in the dataset. Data encryption also shows a dramatic split: Intel records 42,144 versus AMD's 15,716, a 62.7% deficit for the Ryzen part. These two workloads, one compute-heavy and one cryptography-oriented, suggest the Intel part carries substantially more raw execution throughput in these specific tests.

The smallest Intel win is in single-thread performance. The Core Ultra 5 250K Plus posts 4,757 in PassMark single-thread testing against 4,258 for the Ryzen 5 9500F, a 10.5% advantage. That is still a clear win, but it is the closest contest in the entire comparison. For workloads that depend primarily on single-core responsiveness, the AMD chip is comparatively more competitive, even though it does not take the lead.

The multithreaded tests show a large but not overwhelming Intel margin. In PassMark multithread, Intel scores 51,596 against AMD's 28,312, a 45.1% gap. Integer math shows a 32.7% Intel advantage (125,091 versus 84,198). Prime number finding has Intel at 486 versus AMD's 220, a 54.7% gap. Random string sorting goes to Intel by 50.5% (69,090 versus 34,174). Extended instructions favor Intel by 40.8% (44,565 versus 26,370). Physics simulation shows Intel at 3,494 versus AMD's 1,851, a 47% gap.

Looking at the broader database context, the Intel part sits at the 93rd percentile among all CPUs, while the AMD part sits at the 91st. The average benchmark score tells a similar story: Intel records 66,855, AMD records 52,873. Intel's nearest rivals in the database include the AMD EPYC 4465P (delta of 0.1% against Intel) and the Intel Xeon 6515P (0.2% against Intel). AMD's nearest rivals include the AMD Ryzen AI Embedded P164 (0.1% against AMD) and the Intel Xeon 634 (0.2% against AMD). The Ryzen 5 9500F's closest company in average score is the AMD Ryzen 9 7900X, which sits 0.8% above it.

The practical interpretation is straightforward: the Intel Core Ultra 5 250K Plus is the stronger performer in every recorded workload category, with its largest leads in floating-point throughput and encryption and its smallest lead in single-threaded execution. The AMD Ryzen 5 9500F remains a functional desktop processor, but the database does not contain a single benchmark category where it outruns its Intel counterpart.

Architecture Differences

The two processors diverge sharply in their fundamental design. The AMD Ryzen 5 9500F uses the Zen 5 architecture under the Granite Ridge codename, built on TSMC's 4 nm process. The Intel Core Ultra 5 250K Plus uses the Arrow Lake Refresh codename under the Core Ultra Series 2 banner, built on TSMC's 3 nm process. Both are produced by TSMC, but at different nodes.

The core counts could not be more different. AMD fields 6 cores and 12 threads, while Intel fields 18 cores and 18 threads. The Intel part has no hyperthreading-style thread duplication in its recorded thread count, so its 18 threads equal its 18 cores. AMD's 6 cores each carry a second thread, giving it 12 threads total. That core-count disparity is the single most important architectural difference and explains most of the multithreaded benchmark gaps.

Cache hierarchy also differs. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Intel's per-core L1 and L2 are larger, but AMD's shared L3 pool is slightly bigger. Neither part has a 3D V-Cache variant recorded in the database.

Transistor counts and die sizes reflect the different design philosophies. AMD's chip contains 8,315 million transistors on a 70.6 mm² die. Intel's contains 17,800 million transistors on a 243 mm² die. Both are active production parts, and both use the DDR5 memory standard with dual-channel buses. Memory bandwidth differs: AMD records 89.6 GB/s, Intel records 115.2 GB/s. Both support ECC memory.

PCIe connectivity differs as well. AMD provides Gen 5 with 24 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). Intel includes integrated graphics in the form of Arc Xe-LPG Graphics 64EU, while AMD's Ryzen 5 9500F has no integrated graphics at all. Both parts have unlocked multipliers. The AMD part carries part number 100-000001406, the Intel part carries part number SA4UZ.

Clock speeds favor Intel on paper. AMD's base clock is 3.80 GHz with a 5.00 GHz boost. Intel's base clock is 4.20 GHz with a 5.30 GHz boost. Thermal design power shows a major difference: AMD is rated at 65 W, Intel at 125 W. The Intel part draws substantially more power per its TDP rating, consistent with its larger core count and higher clock speeds.

The AMD part released on September 7, 2025. The Intel part released on March 10, 2026. The AMD part belongs to the 9000 series, the Intel part to Core Ultra Series 2. Both are desktop market segment parts with active production status. Both use different sockets: AMD on Socket AM5, Intel on Socket 1851.

Head-to-Head Benchmarks

The full head-to-head dataset shows an Intel sweep across all 11 recorded comparisons. The biggest wins for Intel come in floating-point math and data encryption. In floating-point math, Intel posts 162,692 against AMD's 56,570, a 65.2% advantage. In data encryption, Intel posts 42,144 against AMD's 15,716, a 62.7% advantage. These two workloads show Intel nearly tripling AMD's output in encryption and nearly tripling it again in floating-point throughput.

Prime number finding shows Intel at 486 versus AMD's 220, a 54.7% gap. Random string sorting has Intel at 69,090 versus AMD's 34,174, a 50.5% gap. Physics simulation shows Intel at 3,494 versus AMD's 1,851, a 47% gap. Multithread performance has Intel at 51,596 versus AMD's 28,312, a 45.1% gap. Data compression shows Intel at 568,721 versus AMD's 325,678, a 42.7% gap.

Extended instructions favor Intel by 40.8%, with scores of 44,565 against 26,370. Integer math shows the closest of the compute-heavy tests at 32.7%, with Intel at 125,091 and AMD at 84,198. The single-thread test appears twice in the dataset with identical values: Intel at 4,757, AMD at 4,258, a 10.5% gap in both entries.

The pattern across all benchmarks is consistent. Intel wins every category, and the margin scales roughly with the degree of parallelism and raw throughput required. Single-thread performance is the most competitive area, with Intel ahead by just over 10%. Multithreaded and vector-heavy workloads show Intel ahead by 30% to 65%. The AMD Ryzen 5 9500F's best relative showing is in single-threaded execution, but even there it does not close the gap.

In the database's broader context, the Intel part's average benchmark score of 66,855 places it at the 93rd percentile of all CPUs, while the AMD part's 52,873 places it at the 91st.
