Intel Core 5 221TE vs Intel Core Ultra 5 135HL Comparison

Where Each One Wins

The recorded database contains a complete benchmark profile for the Intel Core 5 221TE, while the Intel Core Ultra 5 135HL has no benchmark entries in the current dataset. This asymmetry shapes the entire comparison: the 221TE can be positioned against a wide field of processors, whereas the 135HL can only be assessed through its architectural specifications and market positioning.

The Core 5 221TE sits at the 71st percentile among all CPUs in the database, with an average benchmark score of 17860. Its nearest rivals include the AMD Ryzen 5 3600XT at 17891 (0.2% ahead of the 221TE), the Intel Core 5 120U at 17898 (0.2% ahead), the Intel Core 7 350 at 17779 (0.5% behind), and the AMD Ryzen 5 1600 at 17994 (0.7% behind). These tight margins place the 221TE in a competitive mid-range cluster where performance differences between adjacent processors are minimal.

The Core Ultra 5 135HL, by contrast, carries a 50th percentile ranking with no recorded average score and no rival comparisons. The data indicates that the 135HL cannot currently be placed within the same performance hierarchy. What the specification sheet does show is a hybrid architecture with 14 cores and 18 threads, a boost clock of 4.60 GHz, and an integrated Arc Xe-LPG 128EU graphics unit. These features point toward workloads that benefit from parallel efficiency and integrated graphics capability, but the absence of measured scores means no direct win can be assigned to the 135HL in any benchmark category.

For the 221TE, the wins are measurable and specific. It delivers a Cinebench R23 multicore score of 11305 and a single-core score of 1596. In PassMark tests, it records 42303 in integer math, 31661 in floating point math, and 156682 in data compression. These numbers establish concrete performance levels for compute-heavy and data-processing tasks. The 135HL, lacking any benchmark data, cannot claim a single measured victory in this database.

Architecture Differences

The two processors diverge substantially in their underlying designs. The Core 5 221TE uses the Bartlett Lake codename, built on a 10 nm process node with a die size of 215 mm². The Core Ultra 5 135HL uses the Meteor Lake architecture, specifically the Meteor Lake-PS codename, built on a 7 nm process node. The smaller process node for the 135HL suggests a denser transistor layout, though the database does not list transistor counts for either chip.

Core configurations differ significantly. The 221TE has 10 cores and 16 threads, while the 135HL has 14 cores and 18 threads. The 135HL therefore offers 4 more cores and 2 more threads. Cache hierarchies also differ: the 221TE provides 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. The 135HL provides 112 KB of L1 per core, 2 MB of L2 per core, but only 18 MB of shared L3. The 221TE thus holds a 6 MB advantage in L3 capacity, while the 135HL has larger per-core L1 and L2 allocations.

Memory support diverges as well. The 221TE supports both DDR4 and DDR5 memory in a dual-channel configuration, with 76.8 GB/s of memory bandwidth and ECC support enabled. The 135HL supports DDR5 only, with the database noting that support depends on the motherboard, also in dual-channel, but with a higher 89.6 GB/s memory bandwidth. The 135HL does not support ECC memory. This makes the 221TE the more flexible option for memory compatibility, while the 135HL offers higher theoretical bandwidth.

PCIe connectivity differs. The 221TE provides Gen 5 with 16 lanes from the CPU, while the 135HL provides Gen 4 with 8 lanes. The 221TE clearly offers more expansion bandwidth and more lanes. Integrated graphics also differ: the 221TE uses UHD Graphics 730, while the 135HL uses Arc Xe-LPG 128EU, a more capable integrated GPU based on Intel's Arc technology.

Sockets separate the two. The 221TE uses Intel Socket 1700, while the 135HL uses Intel Socket 1851. This means they are not interchangeable in the same motherboard. The 221TE launched on January 12, 2025 with a launch MSRP of $232, while the 135HL launched earlier on April 7, 2024 and has no recorded launch MSRP in the database. Both have locked multipliers and both are in active production.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, which means no direct measured comparison exists between the Core 5 221TE and the Core Ultra 5 135HL. The 221TE has a full suite of 17 recorded benchmark results, while the 135HL has none. Without paired measurements, a rigorous side-by-side performance comparison cannot be constructed from the available data.

What can be analyzed is the 221TE's standing against its nearest rivals. In Cinebench R23 multicore, the 221TE scores 11305, and in single-core it scores 1596. These results place it just below the AMD Ryzen 5 3600XT and the Intel Core 5 120U in average score, with deltas of -0.2% for both. It sits slightly above the Intel Core 7 350 by 0.5% and above the AMD Ryzen 5 1600 by 0.7%. The margins are small enough that run-to-run variance could reorder these chips, but the data shows the 221TE performing within a narrow band of its direct competitors.

In PassMark integer math, the 221TE records 42303, a strong result for general-purpose arithmetic workloads. Its floating point math score of 31661 indicates solid performance in scientific and simulation tasks. Data compression reaches 156682, a high figure that suggests efficient handling of compression algorithms. Data encryption scores 8963, and extended instructions score 9655. Prime number finding is notably low at 59, which may indicate a weakness in that specific workload pattern.

The 135HL's architecture suggests it could compete in certain areas. Its 14 cores and 18 threads give it a thread-count advantage of 2 over the 221TE, and its 7 nm process node could imply better power efficiency per operation. Its 89.6 GB/s memory bandwidth is 16.7% higher than the 221TE's 76.8 GB/s. However, its L3 cache is 25% smaller at 18 MB versus 24 MB, and its boost clock is 0.40 GHz lower at 4.60 GHz versus 5.00 GHz. These factors pull in opposite directions, and without recorded benchmarks, the net effect remains unknown.

The Verdict

For users selecting between these two processors strictly on the basis of database measurements, the Core 5 221TE is the only option with verified performance data. Its 71st percentile ranking, average score of 17860, and full benchmark suite allow concrete workload predictions. The Core Ultra 5 135HL offers an appealing specification sheet with more cores, a newer process node, higher memory bandwidth, and a more advanced integrated GPU, but the database contains zero measured results for it.

The 221TE suits scenarios where proven multi-threaded performance matters. Its Cinebench R23 multicore score of 11305 and PassMark multithread score of 13301 indicate solid throughput for rendering, compilation, and data processing. Its 24 MB of L3 cache and 5.00 GHz boost clock support single-thread responsiveness, reflected in its 1596 Cinebench R23 single-core score. The dual-channel DDR4 and DDR5 support, combined with ECC capability, makes it a flexible choice for systems requiring validated memory configurations.

The 135HL targets a different profile. Its 14 cores and 18 threads suggest strong parallel workload capacity, and its Arc Xe-LPG 128EU integrated graphics far exceed the UHD Graphics 730 in the 221TE. For systems that rely heavily on integrated graphics output, the 135HL may deliver a better experience, though the database cannot confirm this with numbers. Its 89.6 GB/s memory bandwidth and 7 nm process node point to a modern, efficient design.

The socket difference matters for platform decisions. Socket 1700 systems are broadly available, while Socket 1851 represents a newer platform. The 221TE's Gen 5 PCIe with 16 lanes provides more expansion headroom than the 135HL's Gen 4 with 8 lanes. Users with high-bandwidth add-in cards or multiple storage devices may prefer the 221TE for this reason alone. The 135HL's ECC absence could disqualify it for certain workstation or server-adjacent workloads, while the 221TE's ECC support makes it viable there.
