The 221TE's nearest rivals include the AMD Ryzen 5 3600XT at 17,891 (0.2% ahead) and the Intel Core 5 120U at 17,898 (0.2% ahead). These rival clusters show that both processors sit near the top of their respective performance tiers, but those tiers are far apart.

Architecture Differences

The two processors come from different Intel product families and fabrication nodes. The Core 5 221TE uses the Bartlett Lake codename and belongs to the Core 5 (Bartlett Lake) generation. It is built on Intel's 10 nm process with a die size of 215 mm². The Core Ultra 5 336H uses the Panther Lake codename, belongs to the Ultra 5 (Panther Lake-H) generation, and is built on Intel's 3 nm process. The database lists no die size for the Panther Lake part.

Core and thread counts differ in an unusual way. The 221TE has 10 cores and 16 threads. The Ultra 5 336H has 16 cores and 16 threads. This means the 221TE uses hyper-threading to reach 16 threads from 10 physical cores, while the Ultra 5 336H has 16 physical cores with no hyper-threading contribution. The 221TE's approach relies on simultaneous multi-threading, whereas the Ultra 5 336H achieves its thread count entirely through physical cores.

Cache hierarchies are substantially different. The 221TE has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The Ultra 5 336H has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Ultra 5 336H provides more than double the L1 and L2 per core, but the 221TE has 6 MB more shared L3. The larger per-core caches on the Ultra 5 336H likely contribute to its single-thread advantage, while the larger L3 on the 221TE does not compensate for the other architectural gaps.

Memory support differs as well. The 221TE supports DDR4 and DDR5, while the Ultra 5 336H supports DDR5 and LPDDR5X. Both use dual-channel memory buses. The memory bandwidth figures are recorded as 76.8 GB/s for the 221TE and 115.2 GB/s for the Ultra 5 336H, a 50% higher bandwidth for the mobile part. The 221TE supports ECC memory, while the Ultra 5 336H does not.

PCIe lane counts also differ. The 221TE provides Gen 5 with 16 lanes (CPU only), while the Ultra 5 336H provides Gen 5 with 12 lanes (CPU only). The desktop part has four additional CPU-attached lanes. Integrated graphics differ: the 221TE uses UHD Graphics 730, while the Ultra 5 336H uses Intel Xe3 Graphics. The Ultra 5 336H's graphics architecture is newer, though the database does not include graphics benchmarks.

Sockets and market segments separate the two clearly. The 221TE uses Intel Socket 1700 and is classified as a Desktop processor. The Ultra 5 336H uses Intel BGA 2540 and is classified as Mobile. The 221TE has a TDP of 45 watts, while the Ultra 5 336H has a TDP of 25 watts. The Ultra 5 336H delivers substantially higher performance while drawing less power according to the rated TDP figures. The 221TE's base clock is 1.80 GHz with a boost of 5.00 GHz. The Ultra 5 336H has a base clock of 1.90 GHz and a boost of 4.60 GHz. The 221TE boosts higher, but the Ultra 5 336H still wins every benchmark, indicating that raw boost frequency is not the determining factor.

Release dates differ by roughly one year. The 221TE has a release date of January 12, 2025. The Ultra 5 336H has a release date of January 4, 2026. Both processors have active production status. Neither has an unlocked multiplier. The part numbers are SRVQS for the 221TE and SA4RD for the Ultra 5 336H. The 221TE has a launch MSRP of $232, while the Ultra 5 336H has no recorded launch MSRP in the database.

The Verdict

The recorded data points to a clear performance hierarchy. The Intel Core Ultra 5 336H outperforms the Intel Core 5 221TE in every single benchmark in the database, with deltas ranging from 31.8% to 80.3%. The average benchmark score of 34,485 for the Ultra 5 336H versus 17,860 for the 221TE places these processors in different performance classes entirely. The Ultra 5 336H sits in the 84th percentile of all CPUs, while the 221TE sits in the 71st percentile.

For applications that stress integer math, such as prime number finding, the Ultra 5 336H's advantage is extreme at 80.3%. For floating point workloads, the 61.6% lead in Passmark floating point math is similarly decisive. The smallest recorded gap, 31.8% in integer math, still represents a substantial margin. No workload category in the database favors the 221TE.

The architecture differences explain the outcome. The Ultra 5 336H uses a 3 nm process versus 10 nm for the 221TE, has more physical cores (16 versus 10), more L1 and L2 cache per core, and higher memory bandwidth (115.2 GB/s versus 76.8 GB/s). The 221TE counters with a higher boost clock (5.00 GHz versus 4.60 GHz), more L3 cache (24 MB versus 18 MB), more PCIe lanes (16 versus 12), ECC support, and a lower launch MSRP of $232. None of these advantages translate into a benchmark win.

The market segments differ, which shapes the appropriate use case. The 221TE is a Desktop processor on Socket 1700, suitable for systems with replaceable CPUs. The Ultra 5 336H is a Mobile processor on BGA 2540, indicating it is soldered to the motherboard and intended for laptops or compact systems. The 221TE's ECC support and larger PCIe lane count suggest it targets stability-oriented desktop builds. The Ultra 5 336H's lower TDP of 25 watts versus 45 watts makes it the more power-efficient choice, and the data shows it is also the faster choice.

The nearest rivals provide additional context. The Ultra 5 336H trades blows with the Intel Core i7-13700HX (0.2% behind) and the Intel Core i5-13450HX (0.4% ahead). The 221TE sits near the AMD Ryzen 5 3600XT (0.2% behind) and the Intel Core 5 120U (0.2% behind). These rival groups confirm that the Ultra 5 336H competes with high-end HX-series mobile processors, while the 221TE competes with mid-range desktop and mobile parts from a previous performance tier.

The verdict from the data is unambiguous: the Intel Core Ultra 5 336H is the superior processor by every measured metric. The only reasons to select the Core 5 221TE would be factors outside the benchmark data: the desktop socket for upgradeability, ECC memory support, or the lower launch MSRP of $232. Within the recorded performance data, the Ultra 5 336H dominates without exception.
