Intel Core 3 305 vs Intel Core 5 213PTE Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the Intel Core 5 213PTE, winning 15 of the 17 head-to-head comparisons. The Intel Core 3 305 takes only 2 wins, both in the single-threaded PassMark tests. The magnitude of the Core 5 213PTE's advantage varies substantially across workloads, ranging from a modest 16.1% lead in extended instructions to a commanding 65.3% lead in integer math.

In Cinebench tests, the Core 5 213PTE consistently outperforms the Core 3 305 by roughly 39.7% across all six variants. The R15 multi-core score of 2192 versus 1322, the R20 multi-core score of 9135 versus 5511, and the R23 multi-core score of 21751 versus 13123 all reflect this same margin. Single-core Cinebench results follow the identical pattern: R15 single-core shows 309 versus 186, R20 single-core shows 1289 versus 777, and R23 single-core shows 3070 versus 1852, each a 39.7% deficit for the Core 3 305.

PassMark results reveal a wider spread. The largest gap appears in integer math, where the Core 5 213PTE scores 93109 against the Core 3 305's 32295, a 65.3% difference. Floating-point math also favors the Core 5 213PTE heavily: 71722 versus 42284, a 41% gap. Data compression shows 261083 versus 146857, a 43.8% difference, while physics tests show 2199 versus 1233, a 43.9% gap. Random string sorting favors the Core 5 213PTE by 41.5% (30106 versus 17623). Data encryption shows a smaller but still clear advantage at 23.5% (14413 versus 11019). Prime number finding shows a 26.8% lead for the Core 5 213PTE (157 versus 115). Extended instructions show the narrowest multi-core gap at 16.1% (16146 versus 13543). The multithread PassMark score favors the Core 5 213PTE by 39.7% (25590 versus 15439).

The only two benchmarks where the Core 3 305 wins are the PassMark single-thread and singlethread tests, which both record the same scores: 3977 for the Core 3 305 versus 3718 for the Core 5 213PTE, a 7% advantage. This single-thread victory stands in contrast to the Cinebench single-core results, where the Core 5 213PTE leads by 39.7%. The divergence between PassMark and Cinebench single-threaded measurements suggests the tests stress different aspects of the core architecture.

The average benchmark score reinforces the overall picture: the Core 5 213PTE averages 32924 while the Core 3 305 averages 18302. In percentile terms, the Core 5 213PTE sits at the 83rd percentile of all CPUs, while the Core 3 305 sits at the 72nd percentile. The nearest rivals for each chip confirm the performance tier separation. The Core 3 305's closest competitors include the Intel Core i3-14100 with an average score of 18318 (0.1% ahead), the Intel Core 5 330 at 18345 (0.2% ahead), the Intel Core 7 360 at 18374 (0.4% ahead), and the AMD Ryzen 5 2600E at 18230 (0.4% behind). The Core 5 213PTE's nearest rivals include the Intel Core i7-12700 at 32942 (0.1% ahead), the AMD Ryzen 7 PRO 6850H at 32812 (0.3% behind), the AMD Ryzen 7 7800X3D at 33079 (0.5% ahead), and the AMD Ryzen 7 8700G at 33089 (0.5% ahead).

The Verdict

The benchmark data indicates that the Intel Core 5 213PTE is the substantially faster processor in nearly every measurable workload. Its 8 cores with 16 threads, compared to the Core 3 305's 6 cores with 6 threads, translate into large multi-threaded advantages that reach as high as 65.3% in integer math and hold steady around 39.7% across Cinebench tests. The Core 5 213PTE also leads in single-core Cinebench tests by the same 39.7% margin, meaning the performance gap is not limited to heavily threaded workloads.

The Intel Core 3 305 does claim a 7% win in PassMark single-thread testing, which indicates that in at least one single-threaded measurement methodology, the Wildcat Lake architecture holds an edge. However, this single result does not offset the broader pattern. The Core 5 213PTE wins every Cinebench test, every multi-core PassMark test, and all but two of the seventeen recorded comparisons.

For users prioritizing raw compute throughput across compression, encryption, physics, and general math workloads, the data clearly points to the Core 5 213PTE. The Core 3 305's higher single-thread PassMark score may appeal to those running lightly threaded applications that align with that specific benchmark, but the Cinebench single-core results contradict that advantage. The Core 5 213PTE also carries a higher percentile ranking (83rd versus 72nd) and a higher average benchmark score (32924 versus 18302).

Architecture Differences

The two processors come from different architectural families and target different market segments. The Intel Core 3 305 uses the Wildcat Lake codename and is built on a 3 nm process node at Intel's foundry. It is classified as a Mobile segment part with 6 cores and 6 threads. The Intel Core 5 213PTE uses the Bartlett Lake codename and is built on a 10 nm process node, also at Intel's foundry. It is classified as a Desktop segment part with 8 cores and 16 threads.

Cache configurations differ notably. The Core 3 305 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core 5 213PTE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. This means the Core 5 213PTE's L3 cache is four times larger in total capacity, which can benefit workloads with large working sets.

The integrated graphics differ as well. The Core 3 305 features Intel Xe3 Graphics with 1 Xe core, while the Core 5 213PTE features UHD Graphics 730. The Core 3 305 also supports a newer memory generation set: DDR5 and LPDDR5X, while the Core 5 213PTE supports DDR4 and DDR5. The Core 5 213PTE includes ECC memory support, which the Core 3 305 lacks.

PCIe capabilities also separate the two. The Core 3 305 provides Gen 4 with 6 lanes (CPU only), while the Core 5 213PTE provides Gen 5 with 16 lanes (CPU only). The Core 3 305 uses a single-channel memory bus with 59.7 GB/s bandwidth, whereas the Core 5 213PTE uses a dual-channel memory bus with 76.8 GB/s bandwidth.

The sockets differ entirely: the Core 3 305 uses Intel BGA 1516, while the Core 5 213PTE uses Intel Socket 1700. This means the two chips are not interchangeable in any platform.

Where Each One Wins

The Intel Core 5 213PTE wins in virtually every compute-heavy category. Cinebench multi-core and single-core tests all favor it by 39.7%. PassMark integer math, floating-point math, data compression, data encryption, physics, prime number finding, extended instructions, multithread, and random string sorting all favor the Core 5 213PTE with margins from 16.1% to 65.3%. For any workload involving heavy math, data processing, compression, or rendering, the Core 5 213PTE is the clear performer.

The Intel Core 3 305 wins only in PassMark single-thread and singlethread tests, both recording 3977 versus 3718, a 7% advantage. Applications that depend on a single thread and align with PassMark's particular measurement methodology could see a benefit from the Core 3 305. Additionally, the Core 3 305 operates at a 15 watt TDP versus the Core 5 213PTE's 45 watt TDP, and it uses a 3 nm process node versus 10 nm, which positions it for lower-power mobile scenarios. Its support for LPDDR5X memory and Intel Xe3 Graphics also targets a different platform type.

The Core 5 213PTE's dual-channel memory bus with 76.8 GB/s bandwidth, 16 PCIe Gen 5 lanes, and 24 MB of L3 cache give it structural advantages for desktop workloads. The Core 3 305's single-channel bus at 59.7 GB/s and 6 PCIe Gen 4 lanes limit data movement capacity. Each processor wins in its intended environment: the Core 5 213PTE for desktop compute, the Core 3 305 for mobile efficiency with a narrower single-thread PassMark edge.
