AMD Ryzen AI 9 365 vs Intel Core 5 221E Comparison

Intel Core 5 221E and AMD Ryzen AI 9 365 are two processors that, on average, land nearly on top of each other. The Intel part averages a benchmark score of 40144, while the AMD part averages 40048, a negligible delta of 0.2%. Both sit at the 87th percentile of all CPUs. Despite this statistical tie, the two chips have entirely different personalities, with the data revealing a clear split between raw computational muscle and specialized throughput.

Where Each One Wins

The Intel Core 5 221E is decisively the compute-oriented processor. Of the 15 head-to-head benchmark comparisons, Intel wins 11. Its victories are concentrated in classic CPU workloads: single-threaded performance, multi-threaded rendering, and mathematical calculations. The Intel chip leads in Cinebench R23 multi-core by 38.7%, and in single-core by an enormous 83.8%. It also dominates in PassMark’s integer math (15.7% ahead), floating-point math (25.8% ahead), and prime number finding (47.9% ahead). This is a processor built for sustained computational throughput, particularly in scenarios that leverage high clock speeds and a large core count.

The AMD Ryzen AI 9 365 wins the remaining 4 benchmarks, but they are not trivial wins. Its advantages lie in specific, often memory-latency-sensitive or instruction-heavy tasks. The AMD chip leads in Cinebench R15 multi-core by 8.1%, a result that contrasts sharply with its loss in the newer R23 version of the same benchmark suite. More significantly, it wins PassMark’s extended instructions test by 27.5%, a massive margin that points to superior handling of specialized instruction sets like AVX-512 or similar. It also edges out Intel in data compression (8.5% ahead) and random string sorting (4.5% ahead), suggesting a memory subsystem or cache hierarchy that is more efficient for certain data movement patterns.

Architecture Differences

The two chips are built on fundamentally different foundations. The Intel Core 5 221E is a desktop part using the Bartlett Lake codename, manufactured on Intel’s 10 nm process, with a die size of 257 mm². It features 14 cores and 20 threads, with a base clock of 2.70 GHz and a boost clock of 5.20 GHz. Its cache layout includes 80 KB of L1 per core, 2 MB of L2 per core, and a shared 24 MB L3. Power is rated at a 65 W TDP, and it supports both DDR4 and DDR5 memory in a dual-channel configuration. It also supports ECC memory. The platform is Intel Socket 1700, using PCIe Gen 5 with 16 CPU lanes.

In contrast, the AMD Ryzen AI 9 365 is a mobile part under the Strix Point codename, built on TSMC’s 4 nm process with a smaller die of 233 mm². It uses a hybrid architecture of Zen 5 and Zen 5c cores, totaling 10 cores and 20 threads. Its base clock is significantly lower at 2.00 GHz, boosting to 5.00 GHz. The cache hierarchy is different: still 80 KB L1 per core, but only 1 MB L2 per core and a smaller shared 16 MB L3. The TDP is much lower at 28 W, highlighting its mobile, power-efficient design. It supports only DDR5 and LPDDR5X memory, lacks ECC support, and uses a different socket (AMD Socket FP8) with PCIe Gen 4 lanes.

These architectural differences explain the benchmark split. The Intel chip’s higher boost clock (5.20 vs 5.00 GHz) and larger L3 cache (24 MB vs 16 MB) contribute to its massive single-thread lead. The AMD chip’s lower TDP and mobile design focus on efficiency, but its smaller L2 cache (1 MB vs 2 MB per core) and lower base clock put it at a disadvantage in raw compute tests. The Intel chip’s support for DDR4 memory is notable for legacy system integration, while the AMD chip’s support for LPDDR5X is aimed at thin-and-light laptops.

Head-to-Head Benchmarks

The most striking result is in Cinebench R23 single-core, where Intel wins 3661 to 1992, a delta of 83.8%. This is not a marginal victory; it is a generational gap in single-thread capability within these two specific parts. The Intel chip’s 5.20 GHz boost clock and 24 MB of L3 cache appear to be decisive factors. In multi-core R23, Intel again wins 25933 to 18698 (38.7% ahead), showing that its 14-core design scales better than AMD’s 10-core configuration in this modern rendering workload.

However, the older Cinebench R15 multi-core test tells a different story. AMD wins 2842 to 2613, an 8.1% advantage. This reversal suggests that the AMD chip’s architecture is better optimized for the older benchmark’s threading model, or that the Intel chip’s performance is more variable across different generations of the Cinebench suite. It is a reminder that benchmark results are workload-specific.

In PassMark’s suite, Intel’s dominance is clear in math-heavy tasks. Intel wins floating-point math 79028 to 62802 (25.8% ahead) and integer math 117813 to 101831 (15.7% ahead). The prime number test is particularly lopsided, with Intel scoring 173 to AMD’s 117, a 47.9% lead. These results paint a picture of a CPU that excels at pure number crunching.

AMD’s wins are more specialized. The extended instructions test is a major victory for AMD, scoring 25113 to Intel’s 18216, a 27.5% lead. This suggests the AMD chip has superior implementation of advanced vector extensions. AMD also wins data compression (354510 vs 324285, 8.5% ahead) and random string sorting (39447 vs 37686, 4.5% ahead). These are memory-bound tasks, and AMD’s performance here indicates a more efficient memory controller or cache design for certain access patterns.

The Verdict

The data supports a clear conclusion: if your priority is raw computational performance, specifically in single-threaded and multi-threaded rendering, the Intel Core 5 221E is the superior choice. Its wins in Cinebench R23 are not just wins; they are dominant, with an 83.8% lead in single-core and a 38.7% lead in multi-core. It also wins the vast majority of PassMark’s compute tests. The 14-core configuration and higher boost clock deliver tangible results in math, physics, and encryption workloads. This is the processor for a desktop workstation that will be used for heavy number crunching or content creation.

The AMD Ryzen AI 9 365 is not without merit. It is a mobile processor with a fraction of the TDP (28 W vs 65 W), making it the only viable choice for battery-powered systems. Its wins in extended instructions (27.5% ahead) and data compression (8.5% ahead) suggest it has a more efficient architecture for specific, modern workloads. If you are running code that leverages advanced CPU instructions, or if your primary tasks are data compression and sorting, the AMD chip is competitive.

However, the overall average benchmark scores are nearly identical (40144 vs 40048), meaning that neither chip is a poor choice. The decision hinges on the platform. The Intel Core 5 221E requires a desktop Socket 1700 motherboard and offers ECC memory support. The AMD Ryzen AI 9 365 is for a mobile FP8 platform, offering LPDDR5X memory support but no ECC. For a fixed desktop workstation, the Intel chip’s compute lead is decisive. For a mobile workstation or a high-performance laptop, the AMD chip’s combination of efficiency and specialized throughput is more appropriate. The benchmark data does not name a single winner; it names two different winners for two different use cases.
