Intel Core 3 305 vs Intel Core 5 221TE Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear overall picture: the Intel Core 3 305 wins 15 of the 17 recorded head-to-head comparisons, while the Intel Core 5 221TE takes only 2 wins. The average benchmark score for the Core 3 305 is 18,302, placing it at the 72nd percentile of all CPUs, versus 17,860 and the 71st percentile for the Core 5 221TE. This is a narrow margin in aggregate performance, but the distribution of wins reveals a distinct pattern.

The Core 3 305 dominates in Cinebench workloads across the board. In Cinebench R15 multi-core, it scores 1,322 against 1,139 for the Core 5 221TE, a 13.8% advantage. The single-core R15 result shows a 14% lead (186 versus 160). This pattern repeats in R20 multi-core (5,511 versus 4,748, 13.8% ahead) and R20 single-core (777 versus 670, also 13.8%). The R23 results follow the same trajectory: multi-core 13,123 versus 11,305 (13.9% ahead), and single-core 1,852 versus 1,596 (13.8% ahead). These consistent deltas across all Cinebench versions indicate a systematic throughput advantage for the Core 3 305 in both lightly threaded and fully threaded rendering tasks.

PassMark results are more split. The Core 5 221TE wins integer math decisively, scoring 42,303 versus 32,295, a 31% advantage. It also edges out the Core 3 305 in data compression, 156,682 versus 146,857, a 6.7% lead. However, the Core 3 305 takes the remaining PassMark tests with substantial margins in several cases. The largest gap appears in single-thread performance, where the Core 3 305 scores 3,977 versus 1,734 for the Core 5 221TE, a 56.4% difference. This is the single biggest delta in the entire head-to-head set.

Other notable PassMark wins for the Core 3 305 include extended instructions (13,543 versus 9,655, 28.7% ahead), floating point math (42,284 versus 31,661, 25.1% ahead), and physics (1,233 versus 977, 20.8% ahead). The prime number test shows a 48.7% advantage (115 versus 59), and data encryption comes in at 18.7% ahead (11,019 versus 8,963). Random string sorting is closer, with the Core 3 305 ahead by only 3.9% (17,623 versus 16,929). The multithread PassMark score also favors the Core 3 305, 15,439 versus 13,301, a 13.8% margin.

Where Each One Wins

The Intel Core 3 305 is the clear winner for single-threaded and lightly threaded workloads. Its PassMark single-thread score of 3,977 is more than double that of the Core 5 221TE, and the 56.4% delta is the largest in the dataset. This translates directly into superior responsiveness in everyday desktop tasks, web browsing, and applications that rely on a few fast cores rather than many slower ones. The Cinebench single-core results reinforce this, with the Core 3 305 leading by 13.8% to 14% across all three versions. For rendering workloads that scale well with thread count, the Core 3 305 still holds the advantage, as shown by its consistent 13.8% to 13.9% lead in every Cinebench multi-core test despite having fewer cores (6 versus 10) and fewer threads (6 versus 16).

The Core 3 305 also wins in PassMark physics, a test that often reflects both CPU speed and memory subsystem efficiency, with a 20.8% margin. Floating point math favors the Core 3 305 by 25.1%, and extended SIMD-style instructions by 28.7%. These results suggest the Core 3 305 has a significantly more efficient per-core execution engine, likely due to its newer process node and microarchitecture.

The Intel Core 5 221TE wins specifically in integer math and data compression. The 31% advantage in integer math is substantial and suggests workloads that are heavy on integer arithmetic, such as certain types of code compilation, database operations, or number crunching that does not rely on floating point, would run faster on the Core 5 221TE. Data compression, where it leads by 6.7%, is a more modest win but still indicates a slight edge in that specific workload type. These two wins, however, are narrow in scope compared to the breadth of the Core 3 305's victories.

For users choosing between these two, the decision hinges on workload type. Software that is single-threaded or uses a modest number of threads will see a large benefit from the Core 3 305. Even heavily threaded rendering tasks favor the Core 3 305, which is notable given its lower core count. The Core 5 221TE is the better choice only for integer-heavy processing and compression tasks, where its higher core and thread count can be leveraged despite lower per-core efficiency.

Specification Differences

The two processors differ substantially in their core configurations and physical specifications. The Intel Core 5 221TE has 10 cores and 16 threads, while the Intel Core 3 305 has 6 cores and 6 threads. The Core 5 221TE operates at a base clock of 1.80 GHz with a boost clock of 5.00 GHz, whereas the Core 3 305 runs at 1.50 GHz base and 4.30 GHz boost. The thermal design power differs significantly: the Core 5 221TE is rated at 45 watts, while the Core 3 305 is rated at 15 watts.

The socket types are not interchangeable. The Core 5 221TE uses Intel Socket 1700, a desktop platform, while the Core 3 305 uses Intel BGA 1516, indicating a mobile form factor. The market segment confirms this: the Core 5 221TE is a desktop part, and the Core 3 305 is a mobile part. Both have locked multipliers.

Memory support diverges as well. The Core 5 221TE supports DDR4 and DDR5 memory over a dual-channel bus with 76.8 GB/s bandwidth and ECC capability. The Core 3 305 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s bandwidth and no ECC. PCIe support also differs: the Core 5 221TE offers Gen 5 with 16 lanes (CPU only), while the Core 3 305 offers Gen 4 with 6 lanes (CPU only).

Integrated graphics are different, with the Core 5 221TE featuring UHD Graphics 730 and the Core 3 305 featuring Intel Xe3 Graphics (1 Xe). Cache configurations also differ, which is covered in the architecture section. The release dates are roughly 15 months apart, with the Core 5 221TE released in January 2025 and the Core 3 305 in April 2026. The launch MSRP for the Core 5 221TE is $232, and the launch MSRP for the Core 3 305 is $309.

Architecture Differences

The two CPUs are built on different microarchitectures and process nodes. The Intel Core 5 221TE uses the Bartlett Lake codename, while the Intel Core 3 305 uses Wildcat Lake. The Core 5 221TE is fabricated on a 10 nm process by Intel, with a die size of 215 mm². The Core 3 305 is fabricated on a 3 nm process, also by Intel, with no die size recorded in the database. The 3 nm node for the Core 3 305 is a significant architectural advantage, as it allows for higher transistor density and efficiency, which helps explain its strong per-core performance despite lower clock speeds.

Cache hierarchies are structured differently. The Core 5 221TE has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and a shared L3 cache of 24 MB. The Core 3 305 has a combined L1 cache of 192 KB, an L2 cache of 2.5 MB, and a shared L3 cache of 6 MB. The Core 5 221TE's larger L3 cache is substantial, providing four times the shared cache of the Core 3 305. However, the Core 3 305's per-core L1 and L2 allocations appear more generous relative to its core count, which contributes to its superior single-thread performance.

The memory controller differences reflect the target platforms. The Core 5 221TE's dual-channel DDR4/DDR5 support with ECC is aimed at desktop workloads that benefit from higher bandwidth and data integrity. The Core 3 305's single-channel DDR5/LPDDR5X support, without ECC, is optimized for mobile power efficiency and compact designs. The 59.7 GB/s bandwidth of the Core 3 305 is lower than the 76.8 GB/s of the Core 5 221TE, yet benchmark results show the Core 3 305 still outperforms in memory-sensitive tests like Cinebench, which suggests the newer memory technology and higher per-core efficiency offset the bandwidth deficit.

The PCIe capabilities also reflect the platform split. The Core 5 221TE provides 16 Gen 5 lanes, suitable for high-end desktop GPUs and NVMe storage. The Core 3 305 provides 6 Gen 4 lanes, adequate for mobile devices with more limited expansion. Both processors are currently marked as Active in production status. The Core 3 305's integrated graphics, Intel Xe3 Graphics with 1 Xe core, represent a newer GPU architecture compared to the UHD Graphics 730 in the Core 5 221TE, though no graphics benchmarks are recorded in the database to quantify the difference.
