CPU Comparison

The Intel Core 5 320 and Intel Core 5 221TE are two fundamentally different processors that happen to share a similar overall benchmark average. The Core 5 320 is a modern, low-power mobile chip based on the 3 nm Wildcat Lake architecture, while the Core 5 221TE is a desktop part built on the 10 nm Bartlett Lake design. Benchmark results show a stark divergence: the Core 5 320 wins 13 of 17 head-to-head tests, dominating single-threaded and efficiency-oriented workloads, while the Core 5 221TE counters with a massive win in Cinebench R23 multi-core and a few other throughput tasks. The data indicates that the Core 5 320 is the better all-around performer for most users, but the 221TE has specific strengths in heavily threaded, sustained workloads.

FAQ

Q: Which processor has the higher single-threaded performance?

A: The Intel Core 5 320 is decisively ahead. In PassMark single-thread testing, it scores 4045 versus 1734 for the Core 5 221TE, a 133.3% advantage. Cinebench R23 single-core results confirm this, with the 320 scoring 1926 compared to 1596 for the 221TE, a 20.7% lead.

Q: Which processor performs better in multi-core workloads?

A: It depends on the benchmark. The Core 5 221TE wins Cinebench R23 multi-core with a score of 11305 versus 6197 for the Core 5 320, a 45.2% advantage. However, the Core 5 320 wins Cinebench R20 multi-core (5462 vs 4748, a 15% lead) and PassMark multithread (15450 vs 13301, a 16.2% lead).

Q: How do their core counts differ?

A: The Core 5 221TE has 10 cores and 16 threads, while the Core 5 320 has 6 cores and 6 threads. This explains the 221TE’s advantage in the Cinebench R23 multi-core test, which scales well with core count.

Q: Which processor is more energy-efficient?

A: The Core 5 320 has a 15W TDP, while the Core 5 221TE has a 45W TDP. This threefold difference in power envelope reflects the 320’s mobile design and 3 nm process node, versus the 221TE’s desktop orientation on a 10 nm node.

Q: Which processor has better encryption performance?

A: The Core 5 320 is clearly superior in encryption tasks. It scores 10984 in PassMark data encryption versus 8963 for the 221TE, a 22.5% advantage, despite the 221TE having more cores.

Architecture Differences

The two processors represent distinct architectural generations and design philosophies. The Intel Core 5 320 is built on a 3 nm process node and uses the Wildcat Lake architecture, while the Intel Core 5 221TE uses the Bartlett Lake architecture on a 10 nm node. This process node difference is substantial, with the 320 being manufactured on Intel’s most advanced node, allowing for higher efficiency and clock speeds within a much lower power envelope.

Core configuration differs markedly. The Core 5 320 has 6 cores and 6 threads, indicating no hyper-threading support. The Core 5 221TE has 10 cores and 16 threads, suggesting a hybrid arrangement of performance and efficiency cores that allows for a higher thread count. The 221TE’s base clock is 1.80 GHz with a boost of 5.00 GHz, while the 320 starts lower at 1.50 GHz but boosts to 4.60 GHz.

Cache hierarchies are also fundamentally different. The Core 5 320 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core 5 221TE has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and a much larger 24 MB of shared L3 cache. The die size for the 221TE is specified at 215 mm², whereas no die size is listed for the 320.

Platform integration differs significantly. The Core 5 320 supports DDR5 and LPDDR5X memory in a single-channel configuration, while the 221TE supports DDR4 and DDR5 in a dual-channel configuration. The 221TE also supports ECC memory, a feature absent on the 320. PCIe capabilities favor the 221TE with Gen 5 and 16 lanes, compared to Gen 4 with 6 lanes on the 320. Integrated graphics are different as well: the 320 features Intel Xe3 Graphics with 2 Xe cores, while the 221TE uses UHD Graphics 730.

Where Each One Wins

The Core 5 320 wins in nearly every category where per-core performance or responsiveness matters. Its single-thread performance is exceptional, with a 133.3% lead in PassMark single-thread and a 72.5% lead in Cinebench R15 single-core. It also excels in encryption (22.5% lead), extended instructions (37.4% lead), prime number finding (86.4% lead), floating-point math (34% lead), physics calculations (25% lead), and random string sorting (6.6% lead). The 320 also wins the PassMark multithread test, suggesting its architecture handles thread scheduling more efficiently despite having fewer cores.

The Core 5 221TE wins where raw core count and large shared cache matter. Its biggest victory is in Cinebench R23 multi-core, where it scores 11305 versus 6197, a 45.2% advantage. It also wins Cinebench R15 multi-core (1139 vs 1054, a 7.5% lead), data compression (156682 vs 148779, a 5% lead), and integer math (42303 vs 32323, a 23.6% lead). These wins point to workloads that scale linearly with more cores and benefit from the larger 24 MB L3 cache.

Head-to-Head Benchmarks

The most dramatic single-thread result is in PassMark single-thread, where the Core 5 320 scores 4045 against the 221TE’s 1734. This 133.3% delta is the largest margin in any test. Cinebench R15 single-core shows a similar pattern, with the 320 at 276 versus 160 for the 221TE, a 72.5% advantage. These results indicate the 320’s architecture delivers vastly superior per-core instructions per clock.

The Core 5 221TE’s biggest win is Cinebench R23 multi-core, where it scores 11305 versus 6197, representing a 45.2% advantage. This is the only test where the 221TE leads by more than 25%. Its other wins are more modest: Cinebench R15 multi-core (1139 vs 1054, 7.5% lead), data compression (156682 vs 148779, 5% lead), and integer math (42303 vs 32323, 23.6% lead).

In Cinebench R20, the results are contradictory. The Core 5 320 wins multi-core with 5462 versus 4748, a 15% lead, and single-core with 771 versus 670, a 15.1% lead. This suggests that in R20, the 320’s efficiency compensates for its lower core count, while in R23, the 221TE’s extra cores become decisive.

The Core 5 320 also dominates in specialized PassMark tests. It leads in data encryption by 22.5%, extended instructions by 37.4%, prime numbers by 86.4%, floating-point math by 34%, physics by 25%, and random string sorting by 6.6%. The PassMark multithread test goes to the 320 with 15450 versus 13301, a 16.2% lead, further evidence that the 320’s thread management is more effective than the 221TE’s raw thread count.

The Verdict

The data clearly favors the Intel Core 5 320 for general-purpose computing. It wins 13 of 17 head-to-head benchmarks, including all single-thread tests and the PassMark multithread test. Its 133.3% lead in PassMark single-thread and 72.5% lead in Cinebench R15 single-core are decisive for everyday tasks like web browsing, office applications, and light content creation that rely on per-core speed. The 320 also offers superior efficiency with its 15W TDP, making it suitable for thin-and-light mobile devices.

The Intel Core 5 221TE is the better choice for specific, heavily threaded workloads that scale with core count and benefit from a large L3 cache. Its 45.2% win in Cinebench R23 multi-core and 23.6% win in integer math indicate strength in rendering, video encoding, and scientific computation. The 221TE also provides dual-channel memory with higher bandwidth and ECC support, making it more appropriate for stable, long-running desktop workloads. Its 5.00 GHz boost clock and 24 MB L3 cache are notable advantages for sustained throughput.

For users who prioritize responsiveness, encryption, and floating-point performance, the Core 5 320 is the superior processor. For users who need maximum multi-threaded throughput in Cinebench R23-style workloads and require ECC memory or PCIe Gen 5 support, the Core 5 221TE is justified. The 320’s higher overall win count and massive single-thread lead make it the recommended processor for most users, while the 221TE serves a narrower but valid niche.
