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

Head-to-Head Benchmarks

The benchmark data presents a decisive outcome: the Intel Core Ultra 7 265 wins every single recorded head-to-head test, taking 17 of 17 comparisons. The Intel Core 5 221TE does not record a single victory in any measured workload. The margins, however, vary significantly depending on the type of task, which reveals where each processor's underlying strengths and weaknesses lie.

The most lopsided results appear in Cinebench testing. In Cinebench R15 multicore, the Core Ultra 7 265 scores 4255 against the Core 5 221TE's 1139, a delta of -73.2% for the Core 5 221TE. The single-core R15 test shows a nearly identical gap: 600 versus 160, also a -73.3% delta. This pattern repeats in Cinebench R23, where the multicore score of 42216 dwarfs the 11305 of the Core 5 221TE, and the single-core score of 5960 versus 1596, both at -73.2%. Interestingly, the Cinebench R20 results tell a different story in terms of magnitude. The multicore score of 6268 beats 4748, a -24.3% gap, and the single-core score of 884 beats 670, a -24.2% gap. The R20 deltas are far smaller than those in R15 and R23, suggesting that the workload scaling properties of this specific test compress the performance difference between the two parts.

The PassMark suite reinforces the overall dominance but with its own distinct spread. The largest single gap in the entire dataset appears in the prime number search test, where the Core Ultra 7 265 scores 418 against a mere 59 for the Core 5 221TE, a -85.9% delta. Floating point math also shows a massive separation: 172776 versus 31661, a -81.7% delta. Data encryption follows closely at -77.8% (40456 vs 8963), and extended instructions at -76.7% (41478 vs 9655). Random string sorting shows a -73.5% delta (63833 vs 16929), while multithread performance lands at -73.2% (49682 vs 13301). Data compression is slightly less extreme at -70% (522983 vs 156682), and integer math at -68.6% (134773 vs 42303). Physics simulation shows a -66.6% gap (2923 vs 977), and the single-thread PassMark result is the smallest margin of all at -63% (4689 vs 1734).

These deltas indicate that the Core Ultra 7 265 does not merely outperform; it often more than triples the Core 5 221TE's output. The smallest relative gap, at -63% in single-threaded PassMark, still represents a substantial 2955-point absolute difference. The pattern suggests that the Core Ultra 7 265's advantage grows with workload complexity and parallelism, as evidenced by the extreme gaps in prime finding, floating point, and encryption, all of which leverage both high core counts and strong per-core efficiency.

Where Each One Wins

Based strictly on the recorded data, the Intel Core Ultra 7 265 wins in every measurable category. There is no workload in the database where the Intel Core 5 221TE posts a higher score. This includes all Cinebench versions (R15, R20, R23) in both multicore and single-core modes, and all nine PassMark subtests covering compression, encryption, extended instructions, prime numbers, floating point math, integer math, multithread, physics, and random string sorting.

The use-case split, therefore, is not about which processor wins a given task, but rather about the degree of victory. For lightly threaded, latency-sensitive tasks such as the PassMark single-thread test, the Core Ultra 7 265 leads by -63%. For heavily parallel workloads such as Cinebench R23 multicore, the lead expands to -73.2%. The most extreme separation occurs in specialized mathematical workloads: prime number calculation at -85.9% and floating point math at -81.7%. These are the workloads where the Core Ultra 7 265's core count and architecture deliver the most disproportionate advantage.

For users or systems relying on the Intel Core 5 221TE, the data shows it holds value in scenarios where the absolute scores are sufficient, and the -63% to -85.9% deficits are acceptable. The Core 5 221TE does record a higher percentile rank in one sense: its percentileVsAllCpus of 71 places it above the majority of all CPUs, while the Core Ultra 7 265 sits at 93. This means the Core 5 221TE is not a weak processor by global standards; it is simply outclassed by this specific rival. The average benchmark score of 17860 for the Core 5 221TE versus 64640 for the Core Ultra 7 265, a 3.6x difference, confirms the hierarchy.

Architecture Differences

The two processors diverge fundamentally in their underlying designs. The Intel Core 5 221TE uses the Bartlett Lake codename and is built on a 10 nm process at Intel's own foundry. It features 10 cores and 16 threads, with a base clock of 1.80 GHz and a boost clock of 5.00 GHz. The Core Ultra 7 265, in contrast, uses the Arrow Lake-S codename, belongs to the Core Ultra Series 2, and is fabricated on a 3 nm process by TSMC. It has 20 cores and 20 threads, with a base clock of 2.40 GHz and a boost clock of 5.30 GHz.

The core and thread counts reveal a key architectural decision. The Core 5 221TE has fewer cores (10) than threads (16), indicating that some cores support Hyper-Threading to produce 16 logical processors. The Core Ultra 7 265 has equal core and thread counts (20 each), suggesting a design without Hyper-Threading, where each core represents one thread. Despite this, the Core Ultra 7 265 still achieves vastly higher multithreaded scores, indicating that its 20 physical cores outperform the 10 physical cores plus 6 additional threads of the Core 5 221TE by a wide margin.

Cache hierarchies also differ substantially. The Core 5 221TE provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3. The Core Ultra 7 265 offers 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The larger per-core caches and higher total L3 in the Core Ultra 7 265 contribute to its superior single-thread performance, which is 63% ahead in the PassMark single-thread test and 73.2% ahead in Cinebench R23 single-core.

The manufacturing and transistor counts further separate the two. The Core Ultra 7 265 lists 17,800 million transistors on a 243 mm² die, while the Core 5 221TE lists no transistor count but has a 215 mm² die. The 3 nm TSMC process versus the 10 nm Intel process explains the ability to pack over 17 billion transistors into a similar die area, enabling the Core Ultra 7 265 to double the core count while increasing clock speeds.

The Verdict

The recorded data leaves no ambiguity. The Intel Core Ultra 7 265 is the superior processor in every benchmark category, with deltas ranging from -63% to -85.9% across all 17 head-to-head tests. Its 20 cores, 20 threads, 3 nm TSMC process, and 30 MB of L3 cache deliver performance that the Core 5 221TE cannot approach, despite the latter's lower TDP and dual memory support.

The Core 5 221TE's only advantages are in specifications, not performance. It supports ECC memory, which the Core Ultra 7 265 does not. It supports DDR4, which the Core Ultra 7 265 does not. It has a lower TDP of 45 W versus 65 W. It uses the older Intel Socket 1700, while the Core Ultra 7 265 uses Intel Socket 1851. These factors make the Core 5 221TE relevant for legacy platforms or specific ECC requirements, but the benchmark data shows it trails in every measured workload.

The Core Ultra 7 265, with a percentile rank of 93 and an average score of 64640, sits among high-end server-class parts, as evidenced by its nearest rivals including AMD EPYC 4464P, EPYC 7343, and EPYC 9124. The Core 5 221TE, at percentile 71, competes with mainstream parts like the AMD Ryzen 5 3600XT and Intel Core 7 350. The delta between these two processors is not incremental; it is generational, driven by a 3 nm versus 10 nm process, double the cores, higher clocks, and a larger memory bandwidth.

For anyone choosing between these two, the data indicates the Core Ultra 7 265 for any compute-intensive task. For the Core 5 221TE, the only justifications are ECC support, DDR4 compatibility, a lower TDP, and the launch MSRP of $232 versus $394. Those who need ECC or must stay on Socket 1700 will find the Core 5 221TE adequate, but the benchmark results show it delivers roughly a quarter to a third of the Core Ultra 7 265's performance in most tests, and far less in specialized math workloads.
