The Verdict

The recorded data presents a clear split between the two processors. The Intel Core 9 273PE has a full suite of benchmark scores, an average benchmark score of 49845, and sits at the 90th percentile among all CPUs. The Intel Core Ultra 5 235TA has no recorded benchmark scores in the database, an average benchmark score of 0, and ranks at the 50th percentile. For any workload measured by the database, the Core 9 273PE is the only option with quantitative performance data.

The Core 9 273PE also offers higher boost clocks (5.70 GHz versus 5.00 GHz), more threads (24 versus 14), more L3 cache (36 MB versus 24 MB), and ECC memory support. The Core Ultra 5 235TA counters with a smaller 3 nm process node, more physical cores (14 versus 12), higher memory bandwidth (102.4 GB/s versus 89.6 GB/s), and a larger per-core L2 cache (3 MB versus 2 MB). Its integrated graphics, Arc Xe-LPG Graphics 24EU, is also a different class of GPU than the UHD Graphics 730 in the Core 9 273PE.

Users who rely on measured multi-threaded performance, single-thread responsiveness, or any of the specific PassMark and Cinebench tests should select the Core 9 273PE. The data shows it delivers scores across all recorded benchmark categories. Users who prioritize process technology, physical core count, memory bandwidth, or the newer Socket 1851 platform would look to the Core Ultra 5 235TA, but they must accept the absence of any benchmark results in the database. The launch MSRP for the Core 9 273PE is $549, and the launch MSRP for the Core Ultra 5 235TA is $269.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries comparing the two processors, and the wins count for each is zero. However, the Core 9 273PE has a complete set of individual benchmark scores, which allows for a detailed analysis of its performance profile. The Core Ultra 5 235TA has no such scores, so all comparative observations must rely on the Core 9 273PE's absolute results and its position relative to other CPUs in the database.

The Core 9 273PE's average benchmark score is 49845. Its nearest rivals in the database are the AMD Ryzen AI Max+ 388 with an average score of 49796 (a delta of 0.1 percent), the Intel Core i5-14600KF with 49394 (0.9 percent ahead), the Intel Core i9-13980HX with 50398 (1.1 percent behind), and the AMD Ryzen AI 9 HX PRO 370 with 50448 (1.2 percent behind). This clustering indicates the Core 9 273PE sits in a tightly contested performance band, slightly ahead of some desktop and mobile parts while slightly trailing others.

In Cinebench R15 multicore, the Core 9 273PE scores 3153, and in single core it scores 445. The R20 results show 13140 multicore and 1855 single core. The R23 results show 31288 multicore and 4417 single core. These numbers indicate strong scaling from R15 to R23, with the multicore score growing substantially as the workload becomes more demanding.

PassMark results for the Core 9 273PE cover a wide range of specialized tests. Integer math scores 139410, floating point math scores 107884, and extended instructions score 24630. Data compression scores 405885, while data encryption scores 22719. Random string sorting scores 45098, and finding prime numbers scores 203. The multithread score is 36810, and the physics score is 3120. The single-thread score is 3650.

The absence of benchmark data for the Core Ultra 5 235TA means the database cannot confirm any performance advantage for that processor. The Core 9 273PE is the only one of the two with measurable results, and its scores span both synthetic rendering tests and real-world-style computational tasks. The Core Ultra 5 235TA's 50th percentile ranking, based on an average score of zero, places it far below the Core 9 273PE's 90th percentile in the overall CPU distribution.

Specification Differences

The two processors differ across nearly every major specification field. The Core 9 273PE has 12 cores and 24 threads, while the Core Ultra 5 235TA has 14 cores and 14 threads. Base clocks are close, with the Core 9 273PE at 2.30 GHz and the Core Ultra 5 235TA at 2.20 GHz. Boost clocks differ more significantly: 5.70 GHz versus 5.00 GHz.

Both processors have a 65 W TDP. The Core 9 273PE uses Intel Socket 1700, while the Core Ultra 5 235TA uses Intel Socket 1851. The Core 9 273PE is codenamed Bartlett Lake and belongs to the Core 9 (Bartlett Lake) generation. The Core Ultra 5 235TA is codenamed Arrow Lake-S, belongs to the Core Ultra Series 2, and uses the Arrow Lake architecture.

Manufacturing details diverge sharply. The Core 9 273PE uses a 10 nm process at Intel. The Core Ultra 5 235TA uses a 3 nm process at TSMC, with 17,800 million transistors and a 243 mm² die size. The Core 9 273PE has no listed transistor count or die size in the database.

Cache hierarchies also differ. The Core 9 273PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core Ultra 5 235TA has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache.

Memory support is another differentiator. The Core 9 273PE supports DDR4 and DDR5, while the Core Ultra 5 235TA supports only DDR5. Both use a dual-channel memory bus, but the Core Ultra 5 235TA has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s. ECC memory is supported on the Core 9 273PE but not on the Core Ultra 5 235TA.

PCIe connectivity differs as well. The Core 9 273PE provides Gen 5 with 16 lanes (CPU only). The Core Ultra 5 235TA provides Gen 5 with 20 lanes (CPU only). Integrated graphics are also different: UHD Graphics 730 for the Core 9 273PE versus Arc Xe-LPG Graphics 24EU for the Core Ultra 5 235TA.

Neither processor has an unlocked multiplier. The release dates differ, with the Core Ultra 5 235TA released on 2025-07-28 and the Core 9 273PE released on 2026-03-08. Both are marked as Active in production status and target the Desktop market segment. Part numbers also differ: SA4QD for the Core 9 273PE and SRWPP for the Core Ultra 5 235TA.

Architecture Differences

The architecture gap between the two processors is substantial. The Core 9 273PE is based on Bartlett Lake, which the database lists under the Core 9 generation. The Core Ultra 5 235TA uses the Arrow Lake architecture and belongs to the Core Ultra Series 2. These are different design families with different implementation targets.

The manufacturing process separates them further. The Core 9 273PE is fabricated on a 10 nm node at Intel. The Core Ultra 5 235TA is fabricated on a 3 nm node at TSMC. The database records 17,800 million transistors for the Core Ultra 5 235TA and a die size of 243 mm². No transistor count or die size is recorded for the Core 9 273PE. The shift to a denser process node for the Core Ultra 5 235TA is a major architectural divergence, though the database does not provide direct performance or efficiency measurements for that part.

Core organization also differs. The Core 9 273PE has 12 cores and 24 threads, indicating that each core supports two threads. The Core Ultra 5 235TA has 14 cores and 14 threads, indicating a one-to-one mapping without simultaneous multithreading. This is a fundamental architectural choice: the Core 9 273PE relies on thread duplication to increase parallelism, while the Core Ultra 5 235TA uses more physical cores but no thread duplication.

Cache architecture reflects these design priorities. The Core 9 273PE has a smaller per-core L1 (80 KB) and L2 (2 MB) but a larger shared L3 (36 MB). The Core Ultra 5 235TA has a larger per-core L1 (192 KB) and L2 (3 MB) but a smaller shared L3 (24 MB). The larger per-core caches on the Core Ultra 5 235TA suggest a design aimed at reducing latency for individual threads, while the larger L3 on the Core 9 273PE provides more shared capacity for multi-threaded workloads.

Memory architecture also differs. The Core 9 273PE supports both DDR4 and DDR5, offering backward compatibility. The Core Ultra 5 235TA supports only DDR5, which pairs with its higher memory bandwidth of 102.4 GB/s. The Core 9 273PE's memory bandwidth is 89.6 GB/s. ECC support is present on the Core 9 273PE and absent on the Core Ultra 5 235TA, which may matter for specific reliability-focused use cases.

PCIe lane counts differ as well, with 16 lanes on the Core 9 273PE and 20 lanes on the Core Ultra 5 235TA, both at Gen 5 speeds. The integrated graphics units represent different architectural families: UHD Graphics 730 versus Arc Xe-LPG Graphics 24EU. The socket change from Intel Socket 1700 to Intel Socket 1851 also indicates a platform-level architectural transition between the two parts.
