Intel Core 3 100UL vs Intel Core 9 273PE Comparison

Where Each One Wins

The recorded data splits these two processors into completely different performance classes. The Intel Core 3 100UL has no benchmark entries in the database, which means every measured performance comparison falls to the Intel Core 9 273PE. The Core 3 100UL sits at the 50th percentile among all CPUs, while the Core 9 273PE reaches the 90th percentile. That gap alone indicates a fundamental difference in intended workload.

The Core 9 273PE carries 12 cores and 24 threads, which makes it suitable for heavily threaded rendering, encoding, and scientific workloads. Its Cinebench R23 multi-core score of 31288 places it well above typical desktop processors. The Core 3 100UL, with 6 cores and 8 threads, targets lighter multitasking and office-oriented tasks, though the database contains no direct benchmark scores to confirm its absolute performance level.

The Core 9 273PE also wins on single-threaded responsiveness. Its Cinebench R23 single-core score of 4417 and PassMark single-thread score of 3650 indicate strong per-core performance. The Core 3 100UL has a boost clock of 4.50 GHz, which should handle everyday applications competently, but without recorded benchmarks, the database cannot quantify its single-thread advantage or deficit.

For data-heavy tasks, the Core 9 273PE shows clear dominance. Its PassMark data compression score of 405885 and data encryption score of 22719 reflect substantial throughput. The Core 3 100UL lacks any recorded entries in these categories, so the comparison remains one-sided.

The Core 9 273PE also leads in memory bandwidth, with a recorded 89.6 GB/s versus no listed figure for the Core 3 100UL. The higher memory bandwidth supports the Core 9's multi-core advantage in bandwidth-sensitive workloads such as database operations and large file processing.

The Core 3 100UL does have one structural advantage: a much lower thermal envelope. Its 15 W TDP versus 65 W for the Core 9 273PE makes it suitable for compact, passively cooled or low-power systems. The database does not list any cooling or power consumption benchmarks, so this remains a specification-level observation rather than a measured result.

Architecture Differences

The two processors come from different architectural lineages. The Core 3 100UL uses Raptor Lake with the Raptor Lake-PS codename, while the Core 9 273PE uses Bartlett Lake. Both are built on Intel's 10 nm process node and fabricated by Intel, but the design philosophies diverge sharply.

Core counts differ significantly: the Core 3 100UL provides 6 cores and 8 threads, while the Core 9 273PE provides 12 cores and 24 threads. The thread count difference suggests the Core 9 273PE uses simultaneous multithreading across all cores, whereas the Core 3 100UL has a more limited threading layout.

Cache hierarchies also differ. The Core 3 100UL has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The Core 9 273PE also has 80 KB of L1 per core, but doubles L2 to 2 MB per core and expands shared L3 to 36 MB. The larger L3 cache on the Core 9 273PE reduces memory latency for frequently accessed data, which contributes to its higher benchmark scores.

Clock speeds favor the Core 9 273PE substantially. The Core 3 100UL has a base clock of 1.20 GHz and a boost clock of 4.50 GHz. The Core 9 273PE has a base clock of 2.30 GHz and a boost clock of 5.70 GHz. The higher base clock means the Core 9 273PE maintains better performance under sustained load, while the higher boost clock provides a peak single-thread advantage.

Memory support is identical on paper: both support DDR4 and DDR5 with dual-channel memory buses. The Core 9 273PE adds a recorded memory bandwidth of 89.6 GB/s, and it supports ECC memory, which the Core 3 100UL does not. ECC support makes the Core 9 273PE more attractive for error-sensitive workloads such as financial modeling or long-running scientific computations.

PCIe connectivity also differs. The Core 3 100UL provides Gen 4 with 8 lanes (CPU only), while the Core 9 273PE provides Gen 5 with 16 lanes (CPU only). The Core 9 273PE offers double the lane count and double the per-lane bandwidth of the previous generation, which matters for high-throughput GPUs and NVMe storage arrays.

Integrated graphics differ as well. The Core 3 100UL uses UHD Graphics 64EU, while the Core 9 273PE uses UHD Graphics 730. The database does not include graphics benchmarks, so relative iGPU performance cannot be quantified. Both should handle basic display output and video playback.

Release dates place the Core 3 100UL in early April 2024 and the Core 9 273PE in early March 2026. The Core 9 273PE is a newer design. The Core 9 273PE has a launch MSRP of $549, while the Core 3 100UL has no listed launch price.

Head-to-Head Benchmarks

The database contains 17 recorded benchmark scores for the Core 9 273PE and zero for the Core 3 100UL. This asymmetry means every head-to-head comparison shows the Core 9 273PE winning by default, though the magnitude of its scores still provides useful context.

In Cinebench R15, the Core 9 273PE scores 3153 in multi-core and 445 in single-core. The multi-core figure indicates strong parallel scaling. In Cinebench R20, the Core 9 273PE scores 13140 multi-core and 1855 single-core. The multi-core to single-core ratio of roughly 7:1 reflects the benefit of its 12-core, 24-thread configuration.

Cinebench R23, the most widely cited rendering benchmark in the database, shows 31288 multi-core and 4417 single-core. The multi-core score places the Core 9 273PE in the top decile of all CPUs. The single-core score of 4417 indicates that even lightly threaded tasks receive a substantial clock speed advantage from the 5.70 GHz boost.

PassMark results reinforce the multi-core story. The multithread score of 36810 pairs with a single-thread score of 3650. Integer math reaches 139410, floating-point math reaches 107884, and extended instructions reach 24630. The data compression score of 405885 is particularly high, suggesting the Core 9 273PE handles compression workloads with ease. Random string sorting hits 45098, which reflects memory and cache efficiency.

Finding prime numbers scores 203, which is a comparatively low figure in the PassMark suite. This indicates that the Core 9 273PE does not excel at this particular integer-heavy, branch-heavy workload, despite strong overall integer performance. Physics scores 3120, which is modest relative to the multithread and math scores.

Comparing the Core 9 273PE to its nearest rivals in the database shows a tight cluster. The AMD Ryzen AI Max+ 388 has an average score of 49796, which is 0.1% below the Core 9 273PE's 49845. The Intel Core i5-14600KF scores 49394, which is 0.9% lower. The Intel Core i9-13980HX scores 50398, which is 1.1% higher. The AMD Ryzen AI 9 HX PRO 370 scores 50448, which is 1.2% higher. These four rivals bracket the Core 9 273PE within a roughly 2.3% total band, indicating that the Core 9 273PE performs essentially at parity with high-end mobile and desktop chips from the same era.

The Core 3 100UL has no rivals listed and no average benchmark score. Its 50th percentile placement suggests it sits in the middle of the database's CPU distribution, but without measured scores, any comparison to the Core 9 273PE remains speculative.

Both processors share the same L1 cache size of 80 KB per core, the same dual-channel memory bus, the same DDR4/DDR5 memory support, the same 10 nm process node, the same Intel Socket 1700, and the same Intel foundry. Neither has an unlocked multiplier. The Core 9 273PE's 90th percentile placement versus the Core 3 100UL's 50th percentile placement reflects the measured performance gap, though the Core 3 100UL's lack of benchmark data limits direct comparison.
