Q: Does either processor have an unlocked multiplier for overclocking?

A: Only the AMD Ryzen Embedded 9900X has an unlocked multiplier. The Intel Core 5 221TE has a locked multiplier, meaning it does not support user overclocking through multiplier adjustment.

Q: Which processor has a larger L3 cache?

A: The AMD Ryzen Embedded 9900X features 64 MB of L3 cache, while the Intel Core 5 221TE has 24 MB of shared L3 cache. The AMD chip's larger cache can benefit workloads with high cache reuse.

Architecture Differences

The AMD Ryzen Embedded 9900X is built on the Zen 5 architecture with the Granite Ridge codename, manufactured on a 4 nm process at TSMC. It uses a dual-chiplet design with a combined die size of 2x 70.6 mm², containing 16,630 million transistors. The processor fits into AMD Socket AM5 and belongs to the Ryzen Embedded 9000 series.

The Intel Core 5 221TE is based on the Bartlett Lake codename, using a 10 nm process from Intel's own foundry. It has a monolithic die size of 215 mm². The socket is Intel Socket 1700, and it is part of the Core 5 generation.

Cache topology differs noticeably. Both processors provide 80 KB of L1 cache per core. For L2, the AMD chip uses 1 MB per core, while the Intel chip uses 1.25 MB per core. The L3 cache is the major divider: AMD offers 64 MB total, while Intel provides 24 MB shared.

Memory controller support also separates the pair. AMD supports only DDR5, while Intel supports both DDR4 and DDR5, giving the Intel part flexibility for older memory platforms. The AMD processor's memory bandwidth is rated at 89.6 GB/s versus 76.8 GB/s for Intel.

Integrated graphics differ as well. The AMD Ryzen Embedded 9900X includes Radeon Graphics, while the Intel Core 5 221TE includes UHD Graphics 730. PCIe connectivity favors AMD with 24 Gen 5 lanes versus 16 on Intel.

The AMD processor has an unlocked multiplier, while the Intel one is locked. Production status is active for both, with the Intel part released on 2025-01-12 and the AMD part on 2025-10-06.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two processors. However, the Intel Core 5 221TE has a full set of measured scores, while the AMD Ryzen Embedded 9900X has no recorded benchmark entries in the database. This absence of data for the AMD chip means a direct numerical comparison is not possible from recorded measurements.

The Intel Core 5 221TE's recorded scores include a Cinebench R23 multi-core result of 11,305 and a single-core result of 1,596. In Cinebench R20, it scores 4,748 multi-core and 670 single-core. Older Cinebench R15 results show 1,139 multi-core and 160 single-core.

PassMark tests for the Intel chip show a multi-thread score of 13,301 and a single-thread score of 1,734. Integer math scores 42,303, floating point math scores 31,661, and extended instructions score 9,655. Data compression reaches 156,682, while data encryption scores 8,963. Prime number finding scores 59, random string sorting scores 16,929, and physics scores 977.

The AMD Ryzen Embedded 9900X, despite its higher core count and clock speeds, has no benchmark scores in the database. This is a significant gap. The Intel part's average benchmark score is 17,860, with a percentile rank of 71 among all CPUs. The AMD part has a percentile rank of 50 but an average benchmark score of 0, reflecting the missing data.

Without measured AMD scores, the database cannot confirm the expected performance advantage from the AMD part's specifications. The Intel Core 5 221TE's nearest rivals include the AMD Ryzen 5 3600XT with an average score of 17,891 and a delta of -0.2%, the Intel Core 5 120U at 17,898 (-0.2%), the Intel Core 7 350 at 17,779 (+0.5%), and the AMD Ryzen 5 1600 at 17,994 (-0.7%). These deltas are all within one percentage point, indicating that the Intel Core 5 221TE performs at a similar level to those established desktop processors.

The Verdict

Based solely on recorded data, the Intel Core 5 221TE is the only one of the two with measurable benchmark results. It has an average benchmark score of 17,860 and sits at the 71st percentile of all CPUs. The AMD Ryzen Embedded 9900X has no recorded benchmarks, so its real-world performance cannot be verified from the database.

For users who need a low-power processor, the Intel Core 5 221TE's 45-watt TDP is substantially lower than the AMD part's 120 watts. The Intel chip also supports both DDR4 and DDR5 memory, which can ease system integration with existing memory modules.

The AMD Ryzen Embedded 9900X offers a higher core count, more threads, higher clocks, more PCIe lanes, and a larger L3 cache on paper. Its unlocked multiplier and newer 4 nm process are additional specification advantages. However, without benchmark data, these advantages remain theoretical.

The Intel Core 5 221TE has a launch MSRP of $232. The AMD part has no listed launch MSRP in the database.

Users who require verified performance numbers should rely on the Intel Core 5 221TE, as its benchmark results are present and consistent with its nearest rivals. Users who can accept unverified specifications might consider the AMD part for its higher core count and PCIe connectivity, but the database provides no evidence of its actual performance.

Where Each One Wins

The Intel Core 5 221TE wins in verified performance data. Its recorded benchmark scores across Cinebench and PassMark tests provide a concrete baseline. Its 45-watt TDP makes it suitable for thermally constrained systems. The dual DDR4/DDR5 memory support allows compatibility with older memory hardware. Its launch MSRP of $232 gives it a listed price point.

The AMD Ryzen Embedded 9900X wins on raw specifications. It offers 20% more cores and 50% more threads, which could benefit heavily threaded workloads if performance scales accordingly. Its 64 MB L3 cache is nearly three times larger than the Intel chip's 24 MB. The 24 PCIe Gen 5 lanes provide more expansion bandwidth than Intel's 16 lanes. The unlocked multiplier enables overclocking for users who need extra performance beyond stock settings. Its 4 nm process node is more advanced than Intel's 10 nm, potentially offering better efficiency per transistor.

For memory-intensive applications, the AMD part's 89.6 GB/s bandwidth exceeds the Intel part's 76.8 GB/s, but only for DDR5 configurations. The Intel part's ability to use DDR4 could be preferable in systems where DDR5 is unavailable or cost-prohibitive.

For server or embedded workloads requiring many cores, the AMD processor's 12-core, 24-thread configuration is the stronger specification. For low-power or legacy-memory deployments, the Intel processor's 45-watt TDP and dual memory support are practical advantages. The database currently supports the Intel part's measured performance, while the AMD part remains unverified.
