AMD Ryzen AI 5 435 vs Intel Core 5 221E Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear picture: the Intel Core 5 221E wins every single recorded head-to-head comparison, taking 15 of 15 tests. The AMD Ryzen AI 5 435 does not secure a single victory in any of the shared workloads. The widest gap appears in Cinebench R23 multi-core, where the Intel part scores 25,933 against the AMD's 11,333, a delta of -56.3% for the Ryzen. That margin is substantial and indicates a fundamental difference in multi-threaded throughput capability.

Single-core performance also favors Intel decisively. In Cinebench R23 single-core, the Core 5 221E records 3,661 points, while the Ryzen AI 5 435 manages 1,816, a -50.4% difference. The same pattern shows in Cinebench R15 single-core: 368 for Intel versus 260 for AMD, a -29.3% gap. These results indicate that the Intel architecture holds a commanding lead in lightly threaded workloads, not just heavily parallel ones.

The PassMark suite reinforces the Intel advantage across every category. In integer math, Intel scores 117,813 against AMD's 61,026, a -48.2% delta. Floating point math shows 79,028 versus 40,627, a -48.6% difference. Find prime numbers, a test sensitive to both core count and clock speed, delivers 173 for Intel and just 58 for AMD, the largest percentage gap in the entire dataset at -66.5%. Physics simulation follows suit: 2,230 for Intel versus 1,075 for AMD, a -51.8% deficit for the Ryzen.

Data compression and encryption workloads show similar trends. Intel leads in data compression with 324,285 points versus 225,374, a -30.5% gap. Data encryption favors Intel 19,205 to 11,110, a -42.2% difference. Random string sorting, another memory and cache sensitive test, sees Intel at 37,686 versus AMD's 24,891, a -34% margin. Extended instructions, the narrowest of the recorded deltas, still goes to Intel: 18,216 versus 16,197, an -11.1% difference.

The PassMark multi-thread score summarizes overall parallel performance: Intel at 30,510 versus AMD at 19,000, a -37.7% gap. Single-thread PassMark results are closer but still favor Intel: 4,147 versus 3,734, a -10% delta. That 10% single-thread gap is the smallest margin found anywhere in the head-to-head data, yet it remains consistent with the broader trend.

Where Each One Wins

The Intel Core 5 221E wins in every measured category, so the use-case split is straightforward from the recorded data. For multi-threaded rendering workloads, Cinebench R23 multi-core shows Intel ahead by more than double the AMD score. That translates directly to faster video rendering, 3D scene compilation, and other fully parallel CPU tasks. The Cinebench R15 multi-core result of 2,613 versus 1,686 reinforces the same conclusion with a -35.5% margin.

For single-threaded responsiveness, the Intel part again dominates. Cinebench R23 single-core at 3,661 versus 1,816 and PassMark single-thread at 4,147 versus 3,734 both indicate faster per-core execution. Applications that rely on one or two threads, such as legacy software, spreadsheet recalculation, or light scripting, would see measurable latency improvements on the Intel platform.

Mathematical and scientific workloads strongly favor Intel. The floating point math score of 79,028 versus 40,627 is nearly double. Integer math follows the same pattern at 117,813 versus 61,026. Prime number finding, a stress test for integer throughput and branch prediction, shows Intel at 173 versus 58. These are the kinds of workloads that scale with core count and clock frequency, both areas where the Intel chip demonstrates superiority in the data.

Memory and I/O intensive tasks also lean Intel. Data compression at 324,285 versus 225,374 and random string sorting at 37,686 versus 24,891 both indicate better sustained throughput with large data sets. The Intel part's larger L3 cache likely contributes to these wins, though the benchmark data alone cannot isolate cache effects from core count or clock speed differences.

The AMD Ryzen AI 5 435 does not win any recorded benchmark, which means no use case in this dataset favors it. However, its lower power envelope and mobile market segment suggest it targets different deployment scenarios, though the current measurements show it trailing in every performance category.

Architecture Differences

The two processors diverge sharply in their underlying designs. The AMD Ryzen AI 5 435 uses Zen 5 architecture with the Gorgon Point codename, built on a 4 nm process at TSMC. It contains 6 cores and 12 threads. The Intel Core 5 221E uses Bartlett Lake architecture on a 10 nm process at Intel, with 14 cores and 20 threads. That core count difference alone explains much of the multi-threaded benchmark gap.

Clock speeds favor Intel as well. The AMD part has a base clock of 2.00 GHz and a boost clock of 4.50 GHz. The Intel part runs at 2.70 GHz base and 5.20 GHz boost. Both base and boost clocks are higher on the Intel chip, contributing to its single-threaded wins. The boost clock difference of 0.70 GHz is substantial for lightly threaded workloads.

Cache hierarchies differ meaningfully. Both processors share the same L1 cache at 80 KB per core. L2 cache differs: AMD uses 1 MB per core, while Intel uses 2 MB per core. The L3 cache presents the largest structural gap. AMD has just 4 MB of L3, while Intel has 24 MB shared. This sixfold difference in last-level cache helps explain Intel's dominance in data compression and string sorting benchmarks, which typically benefit from larger working sets held on-chip.

Memory support shows both commonality and divergence. Both support dual-channel memory with identical memory bandwidth of 89.6 GB/s. Both support ECC memory. However, AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. The Intel part's DDR4 compatibility offers broader platform flexibility, though the benchmark data does not differentiate memory types.

PCIe connectivity also differs. AMD provides Gen 4 with 14 lanes CPU-only. Intel provides Gen 5 with 16 lanes CPU-only. The newer PCIe standard and higher lane count give the Intel platform more headroom for expansion cards and high-speed storage, though no benchmark in the dataset directly measures PCIe throughput.

Integrated graphics split between Radeon 840M on the AMD side and UHD Graphics 730 on Intel. The AMD iGPU is generally positioned as more capable for graphics workloads, but no graphics benchmarks appear in the recorded data. Socket types differ as well: AMD uses FP8, while Intel uses Socket 1700. Market segments reflect the design intent: AMD is classified as mobile, Intel as desktop. The Intel part has a die size of 257 mm², while the AMD die size is not recorded.

The Verdict

The data supports a clear conclusion. The Intel Core 5 221E outperforms the AMD Ryzen AI 5 435 in every recorded benchmark, with margins ranging from -10% in PassMark single-thread to -66.5% in PassMark find prime numbers. The Intel part sits at the 87th percentile of all CPUs in the database, while the AMD part sits at the 80th percentile. The average benchmark score for Intel is 40,144, compared to 28,128 for AMD.

Intel's nearest rivals in the database include the AMD Ryzen 7 7700 at a delta of 0.2%, the AMD Ryzen AI 9 365 at 0.2%, the AMD Ryzen 9 270 at -0.3%, and the Intel Core i9-13905H at -0.4%. This places the Core 5 221E in company with high-end desktop and mobile parts. The AMD Ryzen AI 5 435, by contrast, aligns with the Intel Core i5-13490F at -0.2%, the Intel Core i5-14500T at 0.2%, the AMD Ryzen 5 PRO 8500GE at 0.3%, and the AMD Ryzen 5 PRO 5655G at 0.3%. These rival comparisons confirm that the Intel part competes in a higher performance class.

For users who prioritize raw compute performance in rendering, mathematics, compression, or any CPU-bound workload, the Intel Core 5 221E is the clear choice from the recorded data. Its 14 cores, 20 threads, 5.20 GHz boost clock, and 24 MB L3 cache deliver results that the 6-core, 12-thread AMD part cannot approach. The Intel chip carries a launch MSRP of $232, which may be stated once as reference.

For users who require a mobile form factor with lower power consumption, the AMD Ryzen AI 5 435 fits a different physical and thermal profile with its 28 W TDP versus Intel's 65 W TDP. However, the benchmark data shows no performance scenario where the AMD part wins. The choice between these two parts depends entirely on platform constraints, not on measured performance, since Intel wins all 15 head-to-head tests.
