AMD Ryzen 5 150 vs Intel Core Ultra 5 250K Plus Comparison

Head-to-Head Benchmarks

The benchmark data records a complete sweep for the Intel Core Ultra 5 250K Plus across all eleven head-to-head tests. The AMD Ryzen 5 150 does not register a single win in any measured workload. The largest gap appears in prime number finding, where the Intel chip scores 486 against the AMD chip's 47, a delta of -90.3% from the Intel perspective. That is the most lopsided result in the entire comparison.

The multithreaded PassMark score tells a similar story. Intel posts 51,596 against AMD's 17,492, which is 66.1% behind. The floating point math test shows Intel at 162,692 versus AMD at 35,118, a 78.4% deficit. Physics simulation results are equally one-sided: Intel scores 3,494, AMD scores 806, leaving AMD 76.9% behind. Integer math is the closest of the heavy compute workloads, with Intel at 125,091 and AMD at 62,151, still a 50.3% gap.

Single-thread performance narrows the relative difference but still favors Intel clearly. The Intel Core Ultra 5 250K Plus scores 4,757 in the PassMark single-thread test, while the AMD Ryzen 5 150 scores 3,155. That puts AMD 33.7% behind in the single-thread metric, the smallest delta in the entire set. Data compression shows Intel at 568,721 versus AMD at 211,289, a 62.8% gap. Data encryption lands at 42,144 for Intel and 13,425 for AMD, a 68.1% difference. Extended instructions score 44,565 for Intel and 14,675 for AMD, a 67.1% gap. Random string sorting completes the sweep with Intel at 69,090 and AMD at 22,382, a 67.6% deficit.

The average benchmark score in the database confirms the overall picture. Intel's average sits at 66,855, while AMD's average is 34,881. Intel's nearest rivals in the database include the AMD EPYC 4465P at 66,925 and the Intel Xeon 6515P at 67,006, both within 0.2% of the Intel score. AMD's nearest rivals are the Intel Xeon 6349P at 34,890 and the Intel Core 7 253PTE at 34,962, placing the Ryzen 5 150 in a much lower performance tier. The percentile ranking reinforces this: Intel sits at the 93rd percentile of all CPUs in the database, AMD at the 84th.

Architecture Differences

The architectural split between these two processors is substantial. The AMD Ryzen 5 150 uses the Zen 3+ architecture under the Rembrandt-R codename, fabricated on a 6 nm process by TSMC. The Intel Core Ultra 5 250K Plus belongs to the Arrow Lake Refresh codename within the Core Ultra Series 2, built on a 3 nm process, also by TSMC. The process node difference is three full generations apart in lithography terms.

Core configuration differs sharply. The AMD chip provides 6 cores and 12 threads, relying on simultaneous multithreading to reach its thread count. The Intel chip provides 18 cores and 18 threads, with no multithreading, so each core maps to exactly one thread. That 18-core count versus 6-core count explains much of the multithreaded benchmark gap, though the Intel chip's higher clocks also contribute.

Cache hierarchies are built differently. AMD allocates 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. Intel's L3 is nearly double AMD's, and the per-core L2 allocation is six times larger. The Intel die measures 243 mm² with 17,800 million transistors, while the AMD die measures 210 mm² with no transistor count recorded in the database.

Memory support is DDR5 for both, with dual-channel buses. However, Intel's memory bandwidth is recorded at 115.2 GB/s, while AMD's is 76.8 GB/s. Intel also supports ECC memory, while AMD does not. PCIe connectivity differs as well: Intel provides Gen 5 with 20 CPU lanes, AMD provides Gen 4 with 20 CPU lanes.

Integrated graphics present different options. AMD uses the Radeon 660M, while Intel uses Arc Xe-LPG Graphics with 64 execution units. The market segments differ: AMD is classified as a mobile processor, Intel as a desktop processor. The AMD chip uses an unlocked multiplier, while the Intel chip does not.

Specification Differences

The two processors differ on nearly every specification field recorded in the database. Core count is 6 for AMD versus 18 for Intel. Thread count is 12 versus 18. Base clock is 3.30 GHz for AMD versus 4.20 GHz for Intel. Boost clock is 4.55 GHz for AMD versus 5.30 GHz for Intel. TDP is 35 watts for AMD versus 125 watts for Intel.

Socket types are incompatible. AMD uses Socket FP7, while Intel uses Socket 1851. The process node is 6 nm for AMD and 3 nm for Intel. AMD's architecture is listed as Zen 3+, while Intel's architecture field is null in the database, though its generation is recorded as Ultra 5 (Arrow Lake) with the Arrow Lake Refresh codename.

Cache differs at every level. L1 is 64 KB per core for AMD versus 192 KB per core for Intel. L2 is 512 KB per core for AMD versus 3 MB per core for Intel. L3 is 16 MB shared for AMD versus 30 MB shared for Intel. Memory bandwidth is 76.8 GB/s for AMD versus 115.2 GB/s for Intel. ECC support is absent for AMD and present for Intel.

PCIe generation is Gen 4 for AMD and Gen 5 for Intel, both with 20 CPU lanes. The integrated GPU is Radeon 660M for AMD and Arc Xe-LPG Graphics 64EU for Intel. Market segment is mobile for AMD and desktop for Intel. The production status is active for both. Release dates differ: AMD was released on 2025-09-30, Intel on 2026-03-10. Intel has a recorded launch MSRP of $199, while AMD has no recorded launch MSRP. The multiplier is unlocked on AMD and locked on Intel.

The Verdict

The benchmark data leaves no ambiguity about the performance hierarchy. The Intel Core Ultra 5 250K Plus wins every recorded test, with margins ranging from 33.7% in single-thread work to 90.3% in prime number finding. The average benchmark score is 66,855 for Intel versus 34,881 for AMD, a 91.7% advantage for Intel in the aggregate metric. Intel's 93rd percentile ranking versus AMD's 84th percentile confirms that these chips sit in different performance classes.

The Intel chip's 18 cores and 18 threads, 5.30 GHz boost clock, and 30 MB of L3 cache deliver results that the AMD chip cannot approach. The AMD Ryzen 5 150 does have a 35-watt TDP versus Intel's 125-watt TDP, which indicates a much lower power envelope, but the database does not include power consumption measurements to quantify the efficiency trade-off. The AMD chip also uses an older 6 nm process versus Intel's 3 nm process, though Intel still draws more power based on the TDP figures.

For buyers prioritizing raw performance across the board, the Intel Core Ultra 5 250K Plus is the clear choice from the recorded data. The AMD Ryzen 5 150 occupies a lower performance tier, closer in average score to Intel Xeon 6349P and Core i7-13800H than to the Core Ultra 5 250K Plus. The Intel chip's nearest rivals are the AMD EPYC 4465P and Intel Xeon 6515P, both server-class parts, which indicates that the Core Ultra 5 250K Plus performs at a level above typical desktop competition.

Where Each One Wins

The Intel Core Ultra 5 250K Plus wins in every measured category. The largest advantages appear in prime number finding, floating point math, and physics simulation, where the Intel chip leads by 90.3%, 78.4%, and 76.9% respectively. These are compute-heavy workloads that scale with core count and memory bandwidth, both of which favor the Intel chip. Data encryption and extended instructions also show large gaps of 68.1% and 67.1%, reflecting the Intel chip's broader execution resources.

The AMD Ryzen 5 150 does not win any benchmark, but its smallest deficits appear in single-thread performance at 33.7% and integer math at 50.3%. If the AMD chip has a relative strength, it is in lightly threaded integer work, where the gap narrows compared to heavily threaded workloads. The 35-watt TDP also indicates a much lower power draw, though the database does not provide efficiency measurements to compare performance per watt directly.

For use-case planning based strictly on the data, the Intel Core Ultra 5 250K Plus suits workloads that benefit from many cores and high memory bandwidth: multithreaded rendering, physics simulation, data compression, and encryption. The AMD Ryzen 5 150, with its 6 cores and 12 threads, fits scenarios where the 35-watt TDP and mobile form factor are priorities, though its performance ceiling is substantially lower in every recorded test. The Intel chip's desktop market segment and unlocked multiplier also make it the more flexible option for users who can adjust system settings, while the AMD chip's locked multiplier limits tuning options.
