AMD Ryzen AI 7 450 vs Intel Core 5 221E Comparison

Head-to-Head Benchmarks

The database records 15 head-to-head benchmark comparisons between the Intel Core 5 221E and the AMD Ryzen AI 7 450. The Intel part wins 13 of those tests, while the AMD part takes 2. The overall average benchmark scores sit close: Intel at 40144, AMD at 39485, a gap of roughly 1.7% in favor of Intel. Both processors land in the 87th percentile of all CPUs in the database.

The biggest wins for Intel come in single-core workloads. In Cinebench R23 single-core, Intel scores 3661 against AMD's 2038, a 79.6% advantage. Cinebench R15 single-core shows a 71.2% lead (368 vs 215). PassMark single-thread is closer: Intel at 4147, AMD at 3901, a 6.3% edge. This pattern is consistent: Intel's boost clock of 5.20 GHz versus AMD's 5.10 GHz helps, but the raw score differences suggest more than clock speed alone.

Multi-core results are split. In Cinebench R23 multi-core, Intel wins decisively with 25933 versus 18316, a 41.6% margin. However, in Cinebench R15 multi-core, AMD takes the win: 2713 to 2613, a 3.7% edge. This reversal is notable. The older R15 test favors AMD's architecture, while the newer R23 test rewards Intel's higher core count and thread count.

PassMark multi-thread shows Intel ahead by 15.8% (30510 vs 26350). Integer math goes to Intel by 33.1% (117813 vs 88531), and floating-point math follows with a 45.1% lead (79028 vs 54447). Prime number finding is a landslide: Intel scores 173, AMD only 89, a 94.4% gap. Physics simulation also favors Intel, 2230 to 1578, a 41.3% margin.

AMD's other win is in extended instructions. PassMark extended instructions scores 22400 for AMD versus 18216 for Intel, an 18.7% advantage for AMD. This indicates AMD's Zen 5 core handles certain SIMD or specialized instruction workloads more efficiently.

Data compression is nearly a tie. Intel scores 324285, AMD 315906, a 2.7% lead for Intel. Data encryption favors Intel by 18.2% (19205 vs 16247). Random string sorting goes to Intel by 5.7% (37686 vs 35648).

The overall picture: Intel dominates in single-thread performance, multi-core rendering (R23), and general math throughput. AMD wins only in the older R15 multi-core test and in extended instruction throughput. The delta percentages are not uniform; Intel's wins range from 2.7% to 94.4%, while AMD's wins are 3.7% and 18.7%.

The Verdict

The data clearly favors the Intel Core 5 221E for most workloads. With 14 cores and 20 threads against AMD's 8 cores and 16 threads, Intel has a structural advantage in parallel tasks. The Cinebench R23 multi-core score of 25933 versus 18316 is a 41.6% difference, which is substantial for rendering or compilation workloads.

Single-core performance is not close. Intel's 79.6% lead in Cinebench R23 single-core (3661 vs 2038) and 71.2% lead in R15 single-core (368 vs 215) make Intel the clear choice for lightly threaded applications, everyday responsiveness, and legacy software that relies on one or two threads.

However, the AMD Ryzen AI 7 450 is not without merit. Its 18.7% advantage in extended instructions suggests it handles certain cryptographic or vectorized workloads better. The R15 multi-core win, though smaller, hints that some older multi-threaded software may actually run faster on AMD. The AMD part also draws less power on paper (28W TDP versus 65W), which matters for mobile platforms.

For a desktop system where power draw is less critical, the Intel part is the better all-rounder. For a mobile or power-constrained build, the AMD part's efficiency and extended instruction throughput could tip the scale. The database shows both CPUs in the 87th percentile, so neither is weak; the question is which workload profile matches the user.

Where Each One Wins

Intel Core 5 221E wins in: single-core rendering (Cinebench R23 and R15), multi-core rendering in R23, integer math, floating-point math, prime number finding, physics simulation, data encryption, data compression, random string sorting, and PassMark multi-thread. These are typical CPU workloads: office tasks, code compilation, photo editing, and most gaming scenarios where single-thread performance matters.

The 94.4% lead in prime number finding is a strong indicator for mathematical or scientific computing. The 33.1% lead in integer math and 45.1% lead in floating-point math cover most general-purpose compute. Data encryption at 18.2% ahead means file encryption or secure communications will feel faster on Intel.

AMD Ryzen AI 7 450 wins in: Cinebench R15 multi-core and extended instructions. The R15 multi-core win suggests compatibility with older rendering or simulation software that was optimized for the test's specific workload. The extended instructions win (18.7% ahead) points to workloads like SHA hashing, AES encryption (if using specific instruction paths), or certain signal processing tasks.

For a user who runs a mix of office, web, and occasional rendering, the Intel part wins nearly everywhere. For a user who runs specific AVX-512-like or cryptographic workloads, the AMD part may be faster in those narrow cases, but the overall benchmark average still favors Intel by 1.7%.
