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

The Intel Core 5 221TE and Intel Core Ultra 7 265F occupy different tiers of Intel’s desktop lineup, and the benchmark data confirms a substantial performance gap between them. The Core Ultra 7 265F wins all 17 recorded head-to-head comparisons, with the Core 5 221TE failing to secure a single victory. The average benchmark score for the Core Ultra 7 265F is 64,438, placing it in the 93rd percentile of all CPUs, while the Core 5 221TE averages 17,860, sitting in the 71st percentile. These are not close competitors; the data describes two distinct performance classes.

Head-to-Head Benchmarks

The most decisive margin appears in the Cinebench R23 multi-core test, where the Core Ultra 7 265F scores 41,980 against the Core 5 221TE’s 11,305. That is a 73.1% advantage, and the same delta appears across the R15 and R20 multi-core tests (4,231 vs 1,139 and 17,631 vs 4,748, respectively, each also 73.1%). Single-core results follow a similar pattern: Cinebench R23 single-core shows 5,926 versus 1,596, again a 73.1% gap, while R15 and R20 single-core tests show deltas of 73.2% and 73.1%. The consistency of this percentage across all Cinebench iterations suggests the performance difference scales evenly regardless of workload generation.

PassMark results reveal where the gap widens further. The largest delta is in the find prime numbers test, where the Core Ultra 7 265F scores 416 versus 59, a difference of 85.8%. Floating point math also shows a steep divide: 173,855 compared to 31,661, a delta of 81.8%. Data encryption favors the Core Ultra 7 265F by 77.3% (39,468 vs 8,963), while extended instructions show a 75.4% gap (39,235 vs 9,655). Integer math and data compression both land near 69% deltas (138,078 vs 42,303 and 507,018 vs 156,682, respectively), and multithread performance shows 49,410 versus 13,301, a 73.1% gap.

The narrowest margin in the entire dataset is the PassMark single-thread test, where the Core Ultra 7 265F leads by 63.5% (4,750 vs 1,734). Even this smallest gap is enormous, and it indicates that the Core Ultra 7 265F does not merely scale better across many cores; it also executes single-threaded work substantially faster. The physics test shows a 69.2% gap (3,172 vs 977), and random string sorting sits at 72.9% (62,439 vs 16,929). Every recorded metric, from integer math to encryption to single-core rendering, points in the same direction.

Where Each One Wins

The Core 5 221TE does not win any benchmark in this dataset, so any use-case split must rely on relative strengths rather than absolute victories. The data shows the Core 5 221TE’s best relative performance appears in single-threaded workloads, where its deficit is the smallest (63.5%). That still leaves it far behind, but it suggests the Core 5 221TE’s architecture is comparatively less penalized when only one core is active. For workloads that depend heavily on encryption or prime number calculation, the Core 5 221TE is at its worst, with deltas of 77.3% and 85.8% respectively. These tasks appear to benefit disproportionately from the Core Ultra 7 265F’s newer design and higher core count.

The Core Ultra 7 265F wins everywhere, but its largest advantages are in compute-heavy integer and floating point operations. The 81.8% gap in floating point math and 85.8% gap in prime number finding indicate that the Core Ultra 7 265F is particularly strong in scientific and mathematical workloads. The data also shows the Core Ultra 7 265F’s multithreaded score of 49,410 is 3.7 times the Core 5 221TE’s 13,301, which makes it the clear choice for rendering, compilation, or any parallel processing task. The Core 5 221TE remains functional for light desktop use, but the benchmark data provides no scenario where it outperforms its rival.

Architecture Differences

The two processors come from fundamentally different design generations. The Core 5 221TE uses the Bartlett Lake codename and is built on Intel’s 10 nm process, with a die size of 215 mm². The Core Ultra 7 265F uses the Arrow Lake-S codename and is built on TSMC’s 3 nm process, with a die size of 243 mm² and 17,800 million transistors. The shift to a smaller process node from a different foundry explains part of the performance gap, as the 3 nm design offers greater transistor density and efficiency.

Core counts differ sharply. The Core 5 221TE has 10 cores and 16 threads, indicating a hybrid layout with more threads than cores. The Core Ultra 7 265F has 20 cores and 20 threads, meaning every core contributes a single thread. The Core Ultra 7 265F also doubles the L1 cache per core (192 KB vs 80 KB), more than doubles L2 cache per core (3 MB vs 1.25 MB), and provides 30 MB of shared L3 cache versus 24 MB. These cache differences directly influence the large margins seen in integer math and data compression, where data locality matters.

Memory support also diverges. The Core 5 221TE supports both DDR4 and DDR5, while the Core Ultra 7 265F supports only DDR5. Memory bandwidth reflects this: the Core Ultra 7 265F reaches 102.4 GB/s, compared to 76.8 GB/s for the Core 5 221TE. The Core 5 221TE includes ECC memory support, while the Core Ultra 7 265F does not. PCIe lanes differ as well, with the Core Ultra 7 265F offering Gen 5 with 20 lanes versus Gen 5 with 16 lanes for the Core 5 221TE. The integrated graphics also differ, with the Core 5 221TE featuring UHD Graphics 730 and the Core Ultra 7 265F having no integrated graphics at all.

Specification Differences

The two CPUs differ in every major specification field. The Core 5 221TE has a base clock of 1.80 GHz and a boost clock of 5.00 GHz, while the Core Ultra 7 265F runs at 2.40 GHz base and 5.30 GHz boost. Thermal design power is 45 watts for the Core 5 221TE and 65 watts for the Core Ultra 7 265F. Sockets are incompatible: the Core 5 221TE uses Intel Socket 1700, while the Core Ultra 7 265F uses Intel Socket 1851. The Core Ultra 7 265F belongs to the Core Ultra Series 2 and the Ultra 7 (Arrow Lake) generation, whereas the Core 5 221TE is part of the Core 5 (Bartlett Lake) generation.

Release dates are close but not identical. The Core 5 221TE was released on 2025-01-12, and the Core Ultra 7 265F on 2025-01-06. The launch MSRP for the Core 5 221TE is $232, and for the Core Ultra 7 265F it is $379. Both processors have locked multipliers and are active in production. The Core 5 221TE has part number SRVQS, while the Core Ultra 7 265F has part number SRQCV. The Core Ultra 7 265F’s higher core count, larger caches, faster clocks, and greater memory bandwidth all align with its superior benchmark scores.

The Verdict

The benchmark data leaves no ambiguity. The Intel Core Ultra 7 265F outperforms the Intel Core 5 221TE in every recorded test, with deltas ranging from 63.5% in single-threaded PassMark to 85.8% in prime number calculation. The Core Ultra 7 265F’s 93rd percentile ranking versus the Core 5 221TE’s 71st percentile confirms the gap is not marginal. Users who need maximum multi-core throughput, high memory bandwidth, or fast single-core response should select the Core Ultra 7 265F. Its 20 cores, 30 MB L3 cache, and 5.30 GHz boost clock all contribute to the overwhelming advantage shown in the data.

The Core 5 221TE is the appropriate choice only for scenarios where its 45 watt TDP, ECC memory support, or integrated UHD Graphics 730 are required. It also supports DDR4, which may be relevant for systems reusing older memory modules. Its 10 cores and 16 threads provide basic desktop performance, and its 71st percentile ranking places it above a majority of CPUs, but it cannot compete with the Core Ultra 7 265F in any measured workload. The data indicates a clear hierarchy: the Core Ultra 7 265F is the superior processor for demanding tasks, while the Core 5 221TE serves a more constrained, lower-power role.
