The Intel Core 9 273PTE and the Intel Processor U303L occupy opposite ends of the Intel Socket 1700 spectrum. The Core 9 273PTE is a high-core-count desktop part with a 45 W TDP, 12 cores, and a top boost clock of 5.50 GHz, while the U303L is a low-power mobile processor with 5 cores, 6 threads, and a 15 W TDP. Benchmark data shows the Core 9 273PTE delivers roughly 82nd percentile performance among all CPUs, whereas the U303L sits at the 50th percentile. The U303L has no recorded benchmark scores in the database, so the analysis below relies on the Core 9 273PTE's measured results and the architectural and specification differences between the two parts.

Where Each One Wins

The Core 9 273PTE wins in every measurable compute category because it is the only one of the two with benchmark scores recorded. Its multithreaded performance is substantial: Cinebench R23 multicore reaches 20445 points, Cinebench R20 multicore reaches 8586, and Cinebench R15 multicore reaches 2060. PassMark multithread score is 24054, integer math is 82411, floating point math is 60673, and extended instructions score is 15952. Data compression in PassMark hits 258704, data encryption 14253, random string sorting 28973, and find prime numbers 142. Physics score is 1917. These results position the Core 9 273PTE at the 82nd percentile of all CPUs, with an average benchmark score of 31143.

The U303L has no recorded scores in the database, so it cannot claim any measured win. Its advantages are structural rather than performance-based. It is built for the mobile segment with a 15 W TDP, which indicates a much lower power envelope than the Core 9 273PTE's 45 W TDP. It also carries a smaller integrated graphics unit, UHD Graphics 96EU, compared to the Core 9 273PTE's UHD Graphics 730. The U303L's integrated graphics has more execution units on paper, but without benchmark data, the practical graphics performance cannot be quantified.

The Core 9 273PTE also wins on raw clock speed. Its base clock is 1.40 GHz and boost clock is 5.50 GHz, versus the U303L's 1.20 GHz base and 2.60 GHz boost. The Core 9 273PTE's boost clock is more than double the U303L's boost clock. Single-thread performance reflects this: Cinebench R23 singlecore is 2886, Cinebench R20 singlecore is 1212, Cinebench R15 singlecore is 290, and PassMark single thread is 3433. The U303L has no comparable scores.

Architecture Differences

The Core 9 273PTE is based on Bartlett Lake and belongs to the Core 9 generation. The U303L is based on Raptor Lake and belongs to the Intel Processor generation, with the codename Raptor Lake-PS. Both use a 10 nm process node from Intel, so the manufacturing technology is identical. The foundry is Intel for both.

Core counts differ significantly. The Core 9 273PTE has 12 cores and 24 threads, while the U303L has 5 cores and 6 threads. The Core 9 273PTE therefore has 2.4 times the cores and 4 times the threads. Cache hierarchy also differs. Both have 80 KB L1 per core, but the Core 9 273PTE has 2 MB L2 per core versus the U303L's 1.25 MB L2 per core. L3 cache is 36 MB shared on the Core 9 273PTE versus 12 MB shared on the U303L. That is a 3x difference in shared L3.

The Core 9 273PTE supports PCIe Gen 5 with 16 lanes (CPU only). The U303L supports PCIe Gen 4 with 8 lanes (CPU only). Memory bandwidth is listed for the Core 9 273PTE at 89.6 GB/s, while the U303L has no recorded memory bandwidth figure. Both support DDR4 and DDR5 memory on a dual-channel bus.

ECC memory support is another differentiator. The Core 9 273PTE has ECC memory support enabled, while the U303L does not. Integrated graphics differ: the Core 9 273PTE uses UHD Graphics 730, and the U303L uses UHD Graphics 96EU. Both parts have locked multipliers, so neither offers unlocked overclocking.

Market segments differ. The Core 9 273PTE is a desktop processor, and the U303L is a mobile processor. Both are active in production status. The Core 9 273PTE was released on 2026-03-08, while the U303L was released on 2024-04-07, so the Core 9 273PTE is the newer part by roughly two years.

Head-to-Head Benchmarks

The database has no head-to-head benchmark entries for these two processors, so the comparison relies on the Core 9 273PTE's absolute scores and its position relative to other CPUs in the database. The Core 9 273PTE's average benchmark score is 31143. Its nearest rivals include the Intel Core i7-12700F with an average score of 31081 and a delta of 0.2 percent, the AMD Ryzen 9 8945HS at 31074 with a delta of 0.2 percent, the Intel Core i7-13700TE at 31028 with a delta of 0.4 percent, and the Intel Core i7-12650HX at 31290 with a delta of -0.5 percent. This means the Core 9 273PTE is essentially at parity with those four CPUs, within half a percent in either direction.

The U303L has no average benchmark score and no nearest rivals recorded. Its percentile of 50 places it at the median of all CPUs in the database, but without measured scores, there is no basis for a direct numerical comparison between the two processors.

For the Core 9 273PTE, the largest performance margins appear in multithreaded workloads. The Cinebench R23 multicore score of 20445 is roughly 7 times the singlecore score of 2886. PassMark integer math at 82411 is more than double the floating point math score of 60673. Data compression at 258704 is the highest recorded score in the Core 9 273PTE's benchmark set, far above data encryption at 14253. These numbers indicate a processor heavily weighted toward parallel throughput, which aligns with its 12-core, 24-thread configuration.

The Core 9 273PTE's single-thread PassMark score is 3433, and its Cinebench R23 singlecore is 2886. These are strong single-thread numbers for a desktop part, supported by the 5.50 GHz boost clock. The U303L's boost clock of 2.60 GHz is less than half of that, so the Core 9 273PTE should dominate in latency-sensitive single-thread tasks as well, though no direct U303L scores exist to confirm the margin.

Specification Differences

The two processors differ in nearly every specification field. Core count is 12 versus 5. Thread count is 24 versus 6. Base clock is 1.40 GHz versus 1.20 GHz. Boost clock is 5.50 GHz versus 2.60 GHz. TDP is 45 W versus 15 W. Socket is the same Intel Socket 1700 for both, but the market segment differs: desktop for the Core 9 273PTE, mobile for the U303L.

Cache differences are substantial. L1 cache is identical at 80 KB per core. L2 cache is 2 MB per core on the Core 9 273PTE versus 1.25 MB per core on the U303L. L3 cache is 36 MB shared versus 12 MB shared.

PCIe support differs by generation and lane count. The Core 9 273PTE has PCIe Gen 5 with 16 lanes, while the U303L has PCIe Gen 4 with 8 lanes. Memory bandwidth is 89.6 GB/s for the Core 9 273PTE, with no figure recorded for the U303L. ECC memory is supported on the Core 9 273PTE but not on the U303L. Integrated graphics are UHD Graphics 730 versus UHD Graphics 96EU.

The integrated graphics naming is notable: the U303L's UHD Graphics 96EU carries a higher EU count than the Core 9 273PTE's UHD Graphics 730, but no graphics benchmarks are recorded for either part. The Core 9 273PTE has a launch MSRP of $549, and the U303L has a launch MSRP of $285. Both parts have locked multipliers, and both are active in production. The Core 9 273PTE's part number is SA4QJ, while the U303L's part number is SRPKEQ5CV. The Core 9 273PTE was released on 2026-03-08, and the U303L was released on 2024-04-07.

The Verdict

The data indicates a clear separation between these two processors. The Core 9 273PTE is the only one with measured performance, and its results place it at the 82nd percentile of all CPUs with an average score of 31143. Its 12 cores, 24 threads, 5.50 GHz boost, and 36 MB L3 cache make it a high-throughput desktop part. The U303L, by contrast, has no recorded scores and sits at the 50th percentile. Its 5 cores, 6 threads, 2.60 GHz boost, and 12 MB L3 cache define it as a low-power mobile part.

For workloads that depend on multithreaded throughput, the Core 9 273PTE is the only defensible choice based on the recorded data. Its Cinebench R23 multicore score of 20445 and PassMark multithread score of 24054 demonstrate strong parallel capability. Its nearest rivals, the Core i7-12700F, Ryzen 9 8945HS, and Core i7-13700TE, all score within 0.4 percent of it, confirming it sits in the upper tier of mid-range desktop CPUs.

For workloads that prioritize low power consumption and mobile form factors, the U303L is the only option that fits the profile. Its 15 W TDP is one third of the Core 9 273PTE's 45 W TDP, and its mobile market segment indicates it is intended for compact systems. However, the absence of any benchmark scores means its performance cannot be verified from the database.

The Core 9 273PTE also leads on PCIe connectivity with Gen 5 and 16 lanes versus the U303L's Gen 4 and 8 lanes, and it has ECC memory support that the U303L lacks. The U303L has a higher EU count on its integrated graphics, UHD Graphics 96EU versus UHD Graphics 730, but no graphics benchmarks exist to confirm an advantage. The launch MSRP is $549 for the Core 9 273PTE and $285 for the U303L.

The choice depends on the target system. A desktop user seeking top-tier compute performance from the recorded data should select the Core 9 273PTE. A mobile or low-power build without a need for measured high-end performance would use the U303L, accepting that its capabilities are unverified in the database. The Core 9 273PTE is the newer part by release date, 2026-03-08 versus 2024-04-07, and it is the only one of the two with any benchmark evidence of its capabilities.
