Intel Core 9 273PE vs Intel Processor U302L Comparison

The Intel Core 9 273PE and the Intel Processor U302L occupy different ends of the Intel Socket 1700 platform, and the recorded data shows a clear separation in capability and purpose. The Core 9 273PE, a desktop part from the Bartlett Lake generation, delivers 12 cores and 24 threads, while the U302L, a mobile Raptor Lake-PS processor, offers 5 cores and 6 threads. Their benchmark coverage differs as well: the Core 9 273PE has a full set of Cinebench and PassMark results, whereas the U302L has no recorded benchmark scores in the database. This asymmetry shapes the analysis, allowing direct performance interpretation for the Core 9 273PE while the U302L is assessed primarily through its specifications and architectural role.

Where Each One Wins

The Core 9 273PE wins in every measurable category because it is the only one with recorded benchmark data. Its active production status, desktop market segment, and 65 watt TDP position it as a high-throughput processor for sustained workloads. The U302L, with its 15 watt TDP and mobile segment, targets power-constrained environments where low heat output and energy efficiency matter more than raw compute. The data shows that the Core 9 273PE is designed for tasks like multi-threaded rendering, compilation, and heavy data processing, while the U302L suits lightweight productivity, embedded-like deployments, and portable systems where the 5-core, 6-thread configuration keeps power draw minimal.

The Core 9 273PE achieves a 90th percentile ranking among all CPUs in the database, indicating it outperforms the vast majority of tested processors. Its average benchmark score of 49845 further confirms its position as a strong desktop performer. The U302L, by contrast, sits at the 50th percentile, which is the median performance tier, and its average benchmark score is listed as 0 due to the absence of scores. This means the database has no direct performance evidence for the U302L, so any performance claim about it must remain qualitative. The Core 9 273PE clearly wins on multi-core throughput, single-core speed, and every PassMark subtest, while the U302L wins only in the context of power efficiency and mobility, which are not benchmark categories here.

Architecture Differences

The two processors share the same 10 nm process node and Intel as both manufacturer and foundry, but their underlying designs diverge significantly. The Core 9 273PE comes from the Bartlett Lake generation, specifically labeled as Core 9 (Bartlett Lake), and uses a desktop architecture with no additional architecture descriptor. The U302L uses the Raptor Lake architecture with the codename Raptor Lake-PS, and its generation is listed as Intel Processor (Raptor Lake). This architectural split explains their different core counts and clock speeds.

The Core 9 273PE has 12 cores and 24 threads, indicating hyperthreading support that doubles the thread count. The U302L has 5 cores and 6 threads, which suggests a configuration with one core lacking hyperthreading, likely a mix of performance and efficiency cores common to Raptor Lake designs. The L1 cache is identical at 80 KB per core for both, but the L2 cache differs: the Core 9 273PE has 2 MB per core, while the U302L has 1.25 MB per core. The L3 cache shows an even larger gap, with the Core 9 273PE offering 36 MB shared across all cores, versus 10 MB shared for the U302L. This difference directly impacts multi-threaded workloads that rely on shared data, giving the Core 9 273PE a substantial advantage in cache-sensitive applications.

The integrated graphics also differ. The Core 9 273PE uses UHD Graphics 730, while the U302L uses UHD Graphics 80EU. The "80EU" designation indicates a higher execution unit count, but no benchmark data confirms its actual performance, and the database does not provide comparable graphics scores. PCIe support differs as well: the Core 9 273PE supports PCIe Gen 5 with 16 lanes (CPU only), while the U302L supports PCIe Gen 4 with 8 lanes (CPU only). This makes the Core 9 273PE more suitable for high-bandwidth discrete GPUs and NVMe storage, whereas the U302L is limited to older PCIe standards and fewer lanes.

Memory support is shared in terms of types, as both accept DDR4 and DDR5 with dual-channel memory buses. However, the Core 9 273PE has a recorded memory bandwidth of 89.6 GB/s, while the U302L has no memory bandwidth figure in the database. ECC memory support also differs: the Core 9 273PE supports ECC, while the U302L does not. This makes the Core 9 273PE attractive for workstations and servers that require error-correcting memory, while the U302L targets consumer and mobile use cases where ECC is unnecessary.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, and the win counts for both processors are 0. This means the database contains no direct comparison tests between the Core 9 273PE and the U302L. Despite this absence, the Core 9 273PE's individual benchmark scores provide a complete picture of its performance, while the U302L's lack of scores leaves its performance unquantified.

Looking at the Core 9 273PE's Cinebench results, the data shows a multi-core score of 3153 in Cinebench R15, 13140 in R20, and 31288 in R23. Single-core scores are 445 in R15, 1855 in R20, and 4417 in R23. These numbers indicate strong scaling from single-core to multi-core workloads, with the R23 multi-core score being roughly 7 times the single-core score, reflecting the benefit of 24 threads. The PassMark suite reinforces this: multi-thread score of 36810, integer math at 139410, floating point math at 107884, and data compression at 405885. These are high absolute values, placing the processor in the top 10% of all CPUs.

The nearest rivals for the Core 9 273PE provide context. The AMD Ryzen AI Max+ 388 has an average score of 49796, which is 0.1% higher than the Core 9 273PE's 49845, meaning the two are effectively tied. The Intel Core i5-14600KF scores 49394, which is 0.9% lower, so the Core 9 273PE holds a slight edge. The Intel Core i9-13980HX scores 50398, which is 1.1% higher, making it marginally faster. The AMD Ryzen AI 9 HX PRO 370 scores 50448, which is 1.2% higher. These deltas are all within a narrow 2.3% band, indicating that the Core 9 273PE performs on par with these established rivals, neither dominating nor being dominated by any of them.

Since the U302L has no benchmark scores, no direct comparison to the Core 9 273PE is possible from the database. The data only allows for a specification-level comparison, which shows the Core 9 273PE with 2.4 times the cores, 4 times the threads, a 1.1 GHz higher base clock, and a 3.3 GHz higher boost clock. The L3 cache is 3.6 times larger on the Core 9 273PE. These differences suggest that the Core 9 273PE would outperform the U302L by a wide margin in any CPU-bound workload, but no measured scores confirm this.
