Intel Core 9 273PQE vs Intel Processor U300L Comparison

Head-to-Head Benchmarks

The Intel Core 9 273PQE and the Intel Processor U300L occupy vastly different performance tiers, and the recorded benchmark data confirms this without ambiguity. The Core 9 273PQE delivers an average benchmark score of 66099, placing it in the 93rd percentile of all CPUs in the database. The U300L, by contrast, holds a 50th percentile ranking and has no recorded benchmark scores in the database, meaning there is no direct head-to-head measurement available for these two processors.

The Core 9 273PQE’s Cinebench results illustrate its multi-core dominance. It scores 3950 in Cinebench R15 multi-core, 16459 in R20 multi-core, and 39190 in R23 multi-core. Single-core scores are equally strong: 557 in R15, 2323 in R20, and 5532 in R23. These numbers place it firmly in the high-end desktop segment, as evidenced by its nearest rivals. The database shows the Core 9 273PQE is 0.1% behind the Intel Core Ultra 5 250KF Plus, 0.3% ahead of the AMD Ryzen 9 7950X3D, 1.1% behind the Intel Core Ultra 5 250K Plus, and 1.2% behind the AMD EPYC 4465P. These are marginal differences against some of the strongest processors in the database, confirming that the Core 9 273PQE is a top-tier contender.

PassMark results further reinforce this picture. The Core 9 273PQE scores 585752 in data compression, 29636 in data encryption, 38743 in extended instructions, 198 in prime number finding, 125546 in floating point math, 164629 in integer math, 46107 in multithread, 2754 in physics, 53167 in random string sorting, and 4573 in single-thread performance. These are substantial figures across diverse workloads, indicating a processor that handles both integer-heavy and floating-point-heavy tasks with ease.

Since the U300L has no benchmark scores in the database, the head-to-head comparison is necessarily lopsided. The Core 9 273PQE is the only processor with measurable performance data, and that data demonstrates a clear, decisive advantage in every category where numbers exist. The U300L, with its 5 cores and 6 threads, is a low-power mobile part, and its absence from the benchmark results means the database cannot quantify how far behind it truly sits.

The Verdict

The data is unambiguous: the Intel Core 9 273PQE is a high-performance desktop processor designed for demanding workloads, while the Intel Processor U300L is a low-power mobile chip with no measurable benchmark presence in the database. The Core 9 273PQE’s 93rd percentile ranking, its 12 cores and 24 threads, and its strong Cinebench and PassMark scores all point to a processor suited for heavy multi-threaded tasks, content creation, and scientific computing. Its nearest rivals include the AMD Ryzen 9 7950X3D and Intel Core Ultra 5 variants, all within a 1.2% margin, which means the Core 9 273PQE trades blows with some of the fastest processors available.

The U300L, with its 50th percentile ranking, 5 cores, and 6 threads, is a fundamentally different product. Its 15-watt TDP and mobile market segment indicate it is built for efficiency, not raw throughput. The lack of benchmark scores means the database cannot confirm its exact performance level, but the specifications alone suggest it would be overwhelmed by the Core 9 273PQE in any compute-intensive scenario. For users who need maximum performance, the Core 9 273PQE is the clear choice. For users who prioritize power efficiency in a mobile form factor, the U300L is the only option that fits that profile, though its performance remains unquantified.

Specification Differences

The two processors differ in nearly every measurable specification. The Core 9 273PQE has 12 cores and 24 threads, while the U300L has 5 cores and 6 threads. Base clocks are 3.40 GHz versus 1.20 GHz, and boost clocks are 5.90 GHz versus 4.40 GHz. The TDP difference is stark: 125 watts for the Core 9 273PQE versus 15 watts for the U300L. The Core 9 273PQE supports ECC memory, the U300L does not. PCIe connectivity differs as well, with the Core 9 273PQE offering Gen 5 with 16 lanes (CPU only) and the U300L offering Gen 4 with 8 lanes (CPU only). The integrated graphics are also different: UHD Graphics 770 on the Core 9 273PQE, and UHD Graphics 48EU on the U300L.

The L3 cache is another major divider. The Core 9 273PQE has 36 MB of shared L3 cache, while the U300L has 8 MB. L2 cache per core is 2 MB on the Core 9 273PQE and 1.25 MB on the U300L. Both have 80 KB of L1 cache per core. Memory bandwidth is listed for the Core 9 273PQE at 89.6 GB/s, while the U300L has no recorded memory bandwidth figure. Both processors support DDR4 and DDR5 memory in a dual-channel configuration.

The Core 9 273PQE was released on 2026-03-08, while the U300L was released on 2024-04-07. The Core 9 273PQE has a launch MSRP of $589, and the U300L has a launch MSRP of $107. Neither processor has an unlocked multiplier. The part numbers are SA4Q9 for the Core 9 273PQE and SRPEKSRPEM for the U300L.

Architecture Differences

The Core 9 273PQE uses the Bartlett Lake codename and belongs to the Core 9 (Bartlett Lake) generation. The U300L uses the Raptor Lake architecture and belongs to the Intel Processor (Raptor Lake) generation, with a Raptor Lake-PS codename. Both are manufactured on a 10 nm process node at Intel’s foundry, and both use the Intel Socket 1700.

The core counts reveal a fundamental architectural divide. The Core 9 273PQE is a 12-core, 24-thread desktop part, indicating a design with simultaneous multithreading and a focus on parallel throughput. The U300L is a 5-core, 6-thread mobile part, suggesting a hybrid configuration with fewer performance cores and a strong emphasis on power efficiency. The 15-watt TDP of the U300L is characteristic of a mobile design, whereas the 125-watt TDP of the Core 9 273PQE is typical of a high-end desktop processor.

Cache architecture also differs. The Core 9 273PQE has 2 MB of L2 cache per core, 36 MB of shared L3 cache, and supports ECC memory. The U300L has 1.25 MB of L2 cache per core and 8 MB of shared L3 cache, with no ECC support. The larger caches on the Core 9 273PQE align with its higher-performance positioning, while the smaller caches on the U300L reflect its efficiency-oriented design.

Integrated graphics differ as well. The Core 9 273PQE includes UHD Graphics 770, while the U300L includes UHD Graphics 48EU. The Core 9 273PQE also has more PCIe lanes (16 Gen 5 lanes) compared to the U300L’s 8 Gen 4 lanes, which further separates the two in terms of expansion capability and data throughput.

Where Each One Wins

The Core 9 273PQE wins in every category where benchmark data exists. Its multi-core performance, as shown by Cinebench R23 scores of 39190, is exceptional for tasks like video rendering, 3D simulation, and software compilation. The PassMark physics score of 2754 and multithread score of 46107 indicate strong performance in scientific computing and heavily threaded applications. The data compression score of 585752 and integer math score of 164629 point to strong file archiving and general computation capabilities. Single-thread performance, with a PassMark score of 4573 and Cinebench R23 single-core score of 5532, ensures responsiveness in lightly threaded workloads such as gaming and office productivity.

The U300L has no recorded wins in any benchmark category. Its only advantages are structural: a 15-watt TDP that enables fanless or ultra-slim mobile designs, a mobile market segment, and a lower launch MSRP. The database does not include any performance measurements for this processor, so no workload-specific strengths can be confirmed. Its 5 cores and 6 threads, along with a 4.40 GHz boost clock, suggest it can handle basic tasks like web browsing, document editing, and light media playback, but no benchmark data exists to verify these capabilities.

For users selecting between these two processors, the decision hinges on the intended use case. The Core 9 273PQE is the only choice for demanding, multi-threaded workloads and high-performance desktop computing. The U300L is the only choice for power-constrained, mobile applications where efficiency matters more than raw performance. The database records no scenario in which the U300L outperforms the Core 9 273PQE.
