Intel Core 9 273PTE vs Intel Processor U300L Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the Intel Core 9 273PTE and the Intel Processor U300L, though the comparison is limited by the fact that the U300L has no benchmark entries in the database. The Core 9 273PTE delivers a substantial multi-threaded workload advantage, with Cinebench R23 multicore score of 20,445, while the U300L has no recorded score for this test. The Core 9 273PTE's Cinebench R20 multicore result of 8,586 reinforces this pattern, as does its PassMark multithread score of 24,054.

Single-thread performance follows the same trajectory. The Core 9 273PTE records a Cinebench R23 singlecore score of 2,886, a Cinebench R20 singlecore score of 1,212, and a PassMark single-thread score of 3,433. The U300L has no recorded values for any of these tests. The Core 9 273PTE also posts a Cinebench R15 multicore score of 2,060 and a Cinebench R15 singlecore score of 290, with the U300L again absent from the benchmark table.

The Core 9 273PTE's PassMark subtest results provide additional detail on its workload profile. It scores 258,704 in data compression, 14,253 in data encryption, 15,952 in extended instructions, 142 in find prime numbers, 60,673 in floating point math, 82,411 in integer math, 1,917 in physics, and 28,973 in random string sorting. None of these scores have a counterpart for the U300L, which means the database cannot produce a direct head-to-head delta for any individual test.

The Core 9 273PTE holds an 82nd percentile ranking among all CPUs in the database, while the U300L sits at the 50th percentile. The Core 9 273PTE's average benchmark score of 31,143 places it just 0.2% ahead of the Intel Core i7-12700F (average score 31,081) and 0.2% ahead of the AMD Ryzen 9 8945HS (average score 31,074). It is 0.4% ahead of the Intel Core i7-13700TE (average score 31,028) and 0.5% behind the Intel Core i7-12650HX (average score 31,290). These nearest-rival comparisons put the Core 9 273PTE in a tightly contested performance band where only fractions of a percent separate adjacent entries.

The U300L, by contrast, has no nearest rivals and no average benchmark score recorded. Its 50th percentile placement indicates a middling position in the overall CPU distribution, but the absence of actual benchmark numbers means the database cannot quantify how far behind the Core 9 273PTE it sits in any specific workload.

Where Each One Wins

Based strictly on the recorded data, the Core 9 273PTE wins in every measurable category because it is the only one of the two processors with benchmark results. The U300L cannot be said to win any test that appears in the database, since no scores exist for it.

The Core 9 273PTE's PassMark integer math score of 82,411 and floating point math score of 60,673 indicate strong general-purpose compute capabilities. Its data compression score of 258,704 suggests heavy lifting in compression workloads, while its encryption score of 14,253 points to moderate cryptographic throughput. The extended instructions score of 15,952 covers SIMD-optimized workloads, and the random string sorting score of 28,973 reflects sorting and data manipulation tasks.

For the U300L, the database records no wins and no losses. Its 50th percentile ranking implies it lands near the middle of the CPU performance distribution, but without measured scores, the only defensible statement is that the Core 9 273PTE dominates every benchmark category that has data. The U300L's lower core count, lower boost clock, and lower TDP suggest it is positioned for efficiency-oriented use, but the benchmark database does not contain the numbers to confirm how that translates into actual performance.

Architecture Differences

The two processors come from different Intel design families. The Core 9 273PTE uses the Bartlett Lake codename and belongs to the Core 9 (Bartlett Lake) generation, while the U300L uses the Raptor Lake architecture with the Raptor Lake-PS codename and belongs to the Intel Processor (Raptor Lake) generation. Both are built on Intel's 10 nm process node and manufactured by Intel, but the architectural lineage diverges from there.

Core counts differ sharply. The Core 9 273PTE has 12 cores and 24 threads, while the U300L has 5 cores and 6 threads. The Core 9 273PTE's thread count is exactly double its core count, indicating simultaneous multithreading on all cores. The U300L's 6 threads against 5 cores means only one core benefits from an extra thread.

Cache hierarchies show significant differences in capacity and organization. Both processors use 80 KB of L1 cache per core. The Core 9 273PTE has 2 MB of L2 cache per core, while the U300L has 1.25 MB per core. The shared L3 cache is the largest discrepancy: the Core 9 273PTE has 36 MB shared, while the U300L has 8 MB shared. That is a 4.5x difference in L3 capacity.

Memory support is similar on the surface: both support DDR4 and DDR5 with dual-channel memory buses. The Core 9 273PTE lists a memory bandwidth of 89.6 GB/s, while the U300L has no recorded memory bandwidth value. ECC memory support also differs: the Core 9 273PTE supports ECC, while the U300L does not.

PCIe connectivity is another point of divergence. The Core 9 273PTE uses PCIe Gen 5 with 16 lanes (CPU only), while the U300L uses PCIe Gen 4 with 8 lanes (CPU only). The Core 9 273PTE's integrated graphics is UHD Graphics 730, whereas the U300L has UHD Graphics 48EU. The market segment classifications reflect their intended roles: the Core 9 273PTE is listed as Desktop, and the U300L is listed as Mobile.

Release timing and pricing also separate them. The Core 9 273PTE has a launch MSRP of $549 and a release date in March 2026. The U300L has a launch MSRP of $107 and a release date in April 2024. Neither processor has an unlocked multiplier, so both are locked for overclocking.

Specification Differences

The two processors diverge on nearly every specification field in the database. Core count: 12 versus 5. Thread count: 24 versus 6. Base clock: 1.40 GHz versus 1.20 GHz. Boost clock: 5.50 GHz versus 4.40 GHz. TDP: 45 W versus 15 W. L2 cache per core: 2 MB versus 1.25 MB. L3 cache shared: 36 MB versus 8 MB. Memory bandwidth: 89.6 GB/s versus no recorded value. ECC memory: supported versus not supported. PCIe: Gen 5 with 16 lanes versus Gen 4 with 8 lanes. Integrated graphics: UHD Graphics 730 versus UHD Graphics 48EU. Market segment: Desktop versus Mobile. Launch MSRP: $549 versus $107. Release date: March 2026 versus April 2024. Part number: SA4QJ versus SRPEKSRPEM.

Fields that match include the L1 cache size of 80 KB per core, memory support for both DDR4 and DDR5, the dual-channel memory bus, the 10 nm process node, the Intel foundry, and the locked multiplier. Both processors use Intel Socket 1700.

A: Its average benchmark score of 31,143 is 0.2% ahead of the Intel Core i7-12700F (31,081), 0.2% ahead of the AMD Ryzen 9 8945HS (31,074), 0.4% ahead of the Intel Core i7-13700TE (31,028), and 0.5% behind the Intel Core i7-12650HX (31,290).

The Verdict

The database paints a clear picture: the Intel Core 9 273PTE is the only one of the two with measured performance data, and that data shows a capable desktop processor sitting at the 82nd percentile with an average benchmark score of 31,143. Its nearest rivals, all within 0.5% of its average score, confirm it is positioned among strong mid-to-high-end desktop parts. The 12-core, 24-thread configuration with a 5.50 GHz boost clock, 36 MB of L3 cache, PCIe Gen 5 support, and ECC memory capability makes it a suitable choice for workloads that need substantial multi-threaded throughput, as indicated by its Cinebench R23 multicore score of 20,445 and PassMark multithread score of 24,054.

The Intel Processor U300L, with no benchmark scores in the database, cannot be evaluated on measured performance. Its 50th percentile ranking, 5 cores, 6 threads, 4.40 GHz boost clock, 8 MB L3 cache, and 15 W TDP position it as a low-power mobile-oriented part. The launch MSRP of $107 reflects its entry-level positioning, but the data does not contain any test results to quantify its real-world speed.

For anyone choosing between these two on the basis of the recorded data, the Core 9 273PTE is the only option with demonstrated performance. The U300L's efficiency profile, with a TDP of 15 W versus 45 W, makes it the lower-power choice, but the absence of benchmark numbers means its performance claims cannot be verified from the database. The Core 9 273PTE's 5.50 GHz boost clock, 24 threads, and 36 MB of L3 cache give it the structural advantages on paper, and its measured scores back those advantages up. The U300L lacks any measured scores to argue otherwise.
