Intel Core 5 221TE vs Intel Core Ultra 7 265HX Comparison

Head-to-Head Benchmarks

The recorded data presents a one-sided comparison. Across all 17 head-to-head benchmarks, the Intel Core Ultra 7 265HX wins every single test. The Intel Core 5 221TE does not record a single victory in any benchmark category. The most extreme margin appears in PassMark's find prime numbers test, where the Ultra 7 265HX scores 406 against the 221TE's 59, a delta of -85.5% for the smaller chip. This is the largest percentage gap in the dataset.

Cinebench results follow the same pattern. In Cinebench R23 multi-core, the Ultra 7 265HX scores 40,642 versus 11,305 for the 221TE, a -72.2% delta. Single-core performance in the same test shows 5,737 versus 1,596, again a -72.2% delta. The consistency of this percentage across all three Cinebench versions, R15, R20, and R23, suggests a fixed performance relationship between the two processors that scales uniformly with workload intensity. Each Cinebench iteration, whether single-core or multi-core, reports exactly -72.2% or -72.3% delta, indicating the relative gap does not widen or narrow based on the benchmark version.

PassMark's integer math test shows the smallest multi-threaded gap at -66.7%, with scores of 126,954 for the Ultra 7 265HX and 42,303 for the 221TE. The single-thread PassMark test also shows the smallest overall delta at -61.5%, with 4,500 versus 1,734. This narrower gap in single-threaded integer work hints that the architectural advantage of the Ultra 7 265HX is partially mitigated in lightly threaded, simple arithmetic tasks. However, even in this best case for the 221TE, it still trails by more than half.

The data encryption benchmark records the second largest gap at -77.3%, with 39,472 versus 8,963. Extended instructions follow at -76.3%, with 40,741 versus 9,655. Floating point math shows -80.4%, with 161,605 versus 31,661. Random string sorting shows -72.9%, with 62,458 versus 16,929. Data compression shows -69.4%, with 511,817 versus 156,682. Physics simulation shows -67.2%, with 2,978 versus 977. Multi-threaded PassMark shows -72.3%, with 47,985 versus 13,301. Across every workload type, from compression to encryption, from sorting to physics, the Ultra 7 265HX maintains a commanding lead, with deltas ranging from roughly two-thirds to over four-fifths.

Where Each One Wins

The benchmark data does not identify any workload category where the Intel Core 5 221TE takes the lead. Every recorded test, whether focused on integer math, floating point math, data compression, encryption, extended instructions, prime number finding, random string sorting, physics simulation, or any Cinebench rendering scenario, favors the Intel Core Ultra 7 265HX. The closest contest appears in PassMark single-thread tests, where the Ultra 7 265HX leads by -61.5%, and in integer math, where it leads by -66.7%. These are the smallest deltas, suggesting the 221TE is comparatively less disadvantaged in simple, single-threaded arithmetic workloads.

The Ultra 7 265HX shows its largest relative advantage in prime number finding, encryption, and extended instruction workloads. Prime number finding, which is often sensitive to instruction latency and branch prediction, shows the -85.5% gap. Encryption workloads, which frequently rely on specialized instruction sets, show -77.3%. Extended instructions show -76.3%. These results indicate the Ultra 7 265HX's architectural features, such as its newer process node and larger cache configuration, provide outsized benefits in workloads that depend on advanced instruction processing and cryptographic operations.

For use-case analysis, the data suggests the Ultra 7 265HX is suited for demanding multi-threaded content creation, data compression tasks, and scientific computing involving floating point operations. The 221TE, while slower, still records functional benchmark scores, including 11,305 in Cinebench R23 multi-core and 42,303 in PassMark integer math, indicating it can handle everyday computing tasks, though with significantly lower throughput. The average benchmark score for the 221TE is 17,860, placing it at the 71st percentile of all CPUs. The Ultra 7 265HX averages 63,173, placing it at the 93rd percentile.

Architecture Differences

The two processors differ fundamentally in their underlying architecture. The Intel Core 5 221TE uses the Bartlett Lake codename and belongs to the Core 5 generation. It is built on a 10 nm process node at Intel's foundry. The die size measures 215 mm². In contrast, the Intel Core Ultra 7 265HX uses the Arrow Lake-HX codename, belongs to the Core Ultra Series 2 generation, and is built on a 3 nm process node at TSMC. Its die size measures 243 mm², and it contains 17,800 million transistors, a figure not recorded for the 221TE.

The cache hierarchy differs substantially. The 221TE provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 24 MB of shared L3 cache. The Ultra 7 265HX provides 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. This means the Ultra 7 265HX has more than double the L1 and L2 cache per core, and 6 MB more shared L3 cache. Such cache differences directly impact performance in workloads with repeated data access patterns, which aligns with its stronger results in compression and sorting tests.

The core and thread configurations also diverge. The 221TE has 10 cores and 16 threads, indicating hyper-threading support. The Ultra 7 265HX has 20 cores and 20 threads, suggesting no hyper-threading, but double the physical core count. This core count advantage, combined with the higher boost clock of 5.30 GHz versus 5.00 GHz, explains much of the multi-threaded performance gap. The base clocks differ as well, with the Ultra 7 265HX running at 2.60 GHz versus 1.80 GHz for the 221TE.

The integrated graphics differ. The 221TE uses UHD Graphics 730, while the Ultra 7 265HX uses Arc Xe-LPG Graphics 64EU. The 221TE supports DDR4 and DDR5 memory, while the Ultra 7 265HX supports DDR5 only. The 221TE supports ECC memory, while the Ultra 7 265HX does not. These architecture-level differences point to different design priorities: the 221TE targets reliability and compatibility, while the Ultra 7 265HX targets maximum throughput.
