Intel Core Ultra 5 135H

The Intel Core Ultra 5 135H is a mobile processor from the Core Ultra Series 1 family, built on the Meteor Lake architecture at Intel's 7 nm process. It has 14 cores and 18 threads, with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. The average benchmark score is 29600, placing it at the 86th percentile of all CPUs in the database. The part was released on 2023-12-13 and carries a launch MSRP of $342.

Benchmark Performance

The average benchmark score of 29600 is the primary summary metric for the Ultra 5 135H. At the 86th percentile, it sits above the majority of processors in the database. Cinebench results support that position. In Cinebench R23, the multi-core score is 19080 and the single-core score is 2693. In Cinebench R20, the multi-core score is 8013 and the single-core score is 1131. In Cinebench R15, the multi-core score is 1923 and the single-core score is 271. Across the listed Cinebench results, the multi-core values are consistently much higher than the single-core values in the same test generation, which indicates a design oriented toward many threads. The PassMark multithread score of 22422 and PassMark single-thread score of 3521 show the same relationship.

PassMark subtest scores add detail. Data compression is 251651, data encryption is 15026, extended instructions are 15028, find prime numbers is 89, floating point math is 54867, integer math is 73509, physics is 1482, and random string sorting is 28980. Data compression and integer math are the largest PassMark values in the list, followed by floating point math. Those results point to strong throughput in workloads that move, compress, or process large amounts of data. The find prime numbers score of 89 is the smallest PassMark value in the set and is not representative of the overall processor.

Turning to the nearest-rival list, the aggregate positions are close. The AMD Ryzen 5 PRO 8645HS averages 29641, a delta of -0.1 percent. The Intel Core i5-13500HX averages 29554, a delta of 0.2 percent. The AMD Ryzen AI 7 PRO 360 averages 29682, a delta of -0.3 percent. The AMD Ryzen 9 8945HS averages 29467, a delta of 0.5 percent. The deltas are -0.1, 0.2, -0.3, and 0.5 percent, so the aggregate benchmark differences are small. A workload-specific benchmark would be needed to separate these processors in a given application.

Platform and Compatibility

The processor is built for the mobile segment and uses Intel BGA 2049 as its socket specification. The architecture and codename are both listed as Meteor Lake, and the generation is "Ultra 5 (Meteor Lake)". The production status is Active, and the release date is 2023-12-13. The part number is SRMZ0. The foundry is Intel, and the process node is 7 nm.

The core and cache specifications are as follows: 14 cores, 18 threads, 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 18 MB of shared L3 cache. The TDP is 28, and the multiplier is locked, so the reported 3.60 GHz base clock and 4.60 GHz boost clock are the operating targets.

Memory support is DDR5, with support depending on the motherboard. The memory bus is dual-channel, and the listed memory bandwidth is 89.6 GB/s. ECC memory is not supported. The PCIe interface is Gen 5, with 8 lanes available from the CPU only. Integrated graphics are Arc Xe-LPG 96EU.

For upgrade planning, the BGA 2049 package and the mobile market segment mean the CPU is not a user-replaceable component in the desktop sense. The Active production status confirms availability, but the path to a faster processor is tied to the platform rather than the chip itself.

Who Should Consider It

The workload profile starts with the large multi-core scores. R23 multi-core is 19080, R20 multi-core is 8013, R15 multi-core is 1923, and PassMark multithread is 22422. These numbers indicate a chip that should be considered for CPU rendering, all-core compilation, and other parallel compute tasks. The 86th percentile overall ranking also supports the idea that this is an above-average CPU in the database rather than a basic mobile part.

Single-thread performance is still adequate for general productivity. The R23 single-core score of 2693 and the PassMark single-thread score of 3521 show that the processor can handle responsive desktop applications. The integer math score of 73509 and data compression score of 251651 further suggest common office tasks will be well served.

Data processing workloads have dedicated subtest evidence. Data encryption is 15026 and extended instructions are 15028, which are closely aligned. Random string sorting is 28980, and floating point math is 54867. For encryption, sorting, and floating-point-heavy work, these are the relevant metrics. The physics score of 1482 provides a separate physics result, though it sits far below the larger PassMark scores.

Gamers should note that the data pack does not include game-specific frame rate tests. The Arc Xe-LPG 96EU integrated graphics is the available on-die graphics solution, and the CPU's aggregate position is high, but the benchmark data cannot verify gaming frame rates. Users whose priority is overclocking should not choose this part because the multiplier is locked.

How It Compares

AMD Ryzen 5 PRO 8645HS: This rival averages 29641. The Ultra 5 averages 29600, for a delta of -0.1 percent. The processors are effectively equivalent in aggregate benchmark terms.

Intel Core i5-13500HX: This rival averages 29554. The Ultra 5 leads by a delta of 0.2 percent. The aggregate advantage is small but positive.

AMD Ryzen AI 7 PRO 360: This rival averages 29682, which is higher than the Ultra 5's 29600. The delta is -0.3 percent, meaning the AI 7 PRO 360 holds a narrow aggregate edge.

AMD Ryzen 9 8945HS: This rival averages 29467, which is lower than the Ultra 5's 29600. The delta is 0.5 percent in favor of the Ultra 5, the largest aggregate margin in the nearest-rival set.

Single-Thread vs Multi-Thread Behavior

The difference between multi-thread and single-thread performance is visible across every Cinebench version. In R15, the multi-core result is 1923 and the single-core result is 271. In R20, the multi-core result is 8013 and the single-core result is 1131. In R23, the multi-core result is 19080 and the single-core result is 2693. PassMark records multithread at 22422 and single-thread at 3521. In each case, the multi-core score is larger by a wide margin.

These numbers imply that the processor's strongest use case is all-core throughput. The 14 cores and 18 threads can be saturated by parallel jobs, and the multi-core results show that this CPU rewards thread scaling. For single-threaded workloads, the 4.60 GHz boost clock and the per-core cache of 112 KB L1 / 2 MB L2 are the relevant specifications. Those specifications place single-thread performance in a usable range, but not at the level of the processor's own multi-thread output.

A workload that does not scale across cores will not see the benefit of the 19080 R23 multi-core result. A workload that does scale across cores will. This split matters for software selection: parallel builds and renders will align with the multi-thread scores, while lightly threaded applications will align with the single-core scores.
