Architecture Differences

The Core 9 273PE uses the Bartlett Lake codename, built on a 10 nm process node. The Ultra 5 135HL uses the Meteor Lake architecture and the Meteor Lake-PS codename, built on a 7 nm process node. Both are manufactured by Intel. The Core 9 273PE belongs to the Core 9 (Bartlett Lake) generation, while the Ultra 5 135HL belongs to the Ultra 5 (Meteor Lake-PS) generation.

Cache layouts differ. The Core 9 273PE has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Ultra 5 135HL has 112 KB L1 per core, 2 MB L2 per core, and 18 MB shared L3. The Core 9 273PE’s larger L3 cache provides more shared memory for its 12 cores and 24 threads. The Ultra 5 135HL’s larger L1 cache per core may benefit single-core latency, but its overall cache capacity is smaller.

The Core 9 273PE supports PCIe Gen 5 with 16 lanes, while the Ultra 5 135HL supports PCIe Gen 4 with 8 lanes. This gives the Core 9 273PE a bandwidth advantage for high-speed storage and expansion cards. The Core 9 273PE also supports ECC memory, which is absent on the Ultra 5 135HL.

The process node difference, 10 nm versus 7 nm, indicates that the Ultra 5 135HL uses a newer manufacturing process. The Ultra 5 135HL’s lower TDP of 45 watts versus 65 watts may reflect the efficiency of the 7 nm node, but its lower boost clock and smaller L3 cache suggest a more conservative performance profile.

Where Each One Wins

The Intel Core 9 273PE wins on raw performance metrics. Its recorded Cinebench R23 multi-core score of 31288 and single-core score of 4417 place it well ahead of the unmeasured Ultra 5 135HL. The PassMark multi-thread score of 36810 and integer math score of 139410 indicate strong compute throughput for tasks like video encoding, 3D rendering, and scientific simulations. The higher boost clock of 5.70 GHz gives it an edge in lightly threaded workloads where single-core speed matters.

The Core 9 273PE also wins on memory bandwidth potential with its support for both DDR4 and DDR5, though the actual bandwidth figure of 89.6 GB/s is identical to the Ultra 5 135HL. Its larger L3 cache of 36 MB shared versus 18 MB shared benefits workloads with large working sets, such as database queries and complex simulations. The PCIe Gen 5 support with 16 lanes provides a bandwidth advantage for modern GPUs and NVMe storage.

The Ultra 5 135HL wins on power efficiency. Its TDP of 45 watts is lower than the Core 9 273PE’s 65 watts. For systems with limited cooling or power budgets, the Ultra 5 135HL presents a lower-load option. Its integrated graphics, Arc Xe-LPG 128EU, is a more advanced solution than the UHD Graphics 730 on the Core 9 273PE, which could benefit systems without a discrete GPU.

The Ultra 5 135HL also uses the newer 7 nm process node, which may contribute to its lower power draw. Its 14 cores, though fewer threads, could help in certain multi-core scenarios where core count matters more than thread count, but without benchmark data this cannot be confirmed.

For users prioritizing proven performance, the Core 9 273PE is the clear choice. For users prioritizing lower power consumption and a more capable integrated GPU, the Ultra 5 135HL offers those features, but its performance remains unverified. The database records only the Core 9 273PE’s benchmark results, so any performance-based selection should favor that processor.
