Intel Core Ultra 5 125UL

The Intel Core Ultra 5 125UL is an active desktop processor in the Core Ultra Series 1, built on the Meteor Lake architecture (Meteor Lake-PS) using Intel's 7 nm process. It pairs 12 cores with 14 threads, a 1.30 GHz base clock, and a 4.30 GHz boost clock. The part uses Intel Socket 1851 and carries a 15 W TDP. The record lists an all-CPU percentile of 50 and an average benchmark score of 0; no benchmark entries or nearest-rival deltas are present. Its launch MSRP is $309.

Benchmark Performance

The data table contains no benchmark scores for the Core Ultra 5 125UL. The avgBenchmarkScore field is 0, and the nearestRivals array is empty, so there are no named comparison products, no rival scores, and no deltaPct values to analyze. The only comparative marker is percentileVsAllCpus at 50, which places the CPU at the midpoint of the database's all-CPU distribution. Because no measured results accompany that rank, it should be treated as a database position rather than a benchmark-confirmed performance tier.

The specifications that remain available for analysis are the 12 cores, 14 threads, 1.30 GHz base, 4.30 GHz boost, 112 KB L1 per core, 2 MB L2 per core, and 12 MB shared L3. The 14-thread count for a 12-core part gives the OS more hardware threads than physical cores, which can help parallel scheduling. The 4.30 GHz boost figure is the highest clock in the record and is the only boost-side performance datum.

Without benchmark output, the record cannot substantiate percentage deltas ahead of or behind any other CPU. It also cannot quantify real-world differences between single-thread and multi-thread workloads. The architectural picture is one of a 12-core, low-TDP processor with a wide base-to-boost clock span and a moderately large shared L3. In the absence of scores, any conclusion about ranking must remain anchored to the 50th percentile field and the listed specifications.

Platform and Compatibility

The Core Ultra 5 125UL is specified for Intel Socket 1851. Its market segment is Desktop, its production status is Active, its part number is SRN96, and its release date is 2024-04-07. A desktop motherboard with Socket 1851 is therefore the required platform.

Memory support is DDR5, with the record noting that the specific configuration depends 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 4 with 8 lanes provided by the CPU only. That lane count is a CPU-centric constraint: any additional PCIe connectivity beyond the 8 CPU lanes must be accounted for by the platform rather than by the processor record.

The processor includes integrated graphics in the form of Arc Xe-LPG 64EU, so a separate graphics card is not necessary for basic display output. The multiplier is not unlocked, so user-controlled frequency adjustment through the multiplier is not supported. The architecture is Meteor Lake, also identified as Meteor Lake-PS, with generation listed as Ultra 5 (Meteor Lake-PS). The process node is 7 nm and the foundry is Intel.

These platform facts define both the compatibility envelope and the upgrade context: the part is a current, active Socket 1851 desktop processor with motherboard-dependent DDR5 memory and a limited CPU-only PCIe lane allocation.

Who Should Consider It

Because the record contains no benchmark scores, the following recommendations are grounded in the listed specifications instead of measured results.

For general office use, the 1.30 GHz base and 4.30 GHz boost provide a wide clock range, and the 15 W TDP indicates a low-power system; the integrated Arc Xe-LPG 64EU removes the need for a discrete component simply to generate a display output.

For creation workloads, the relevant resources are the 12 cores, 14 threads, 12 MB shared L3, and dual-channel DDR5 with 89.6 GB/s bandwidth. These values point toward a processor that can handle parallel creation tasks, although no benchmark data in the record verifies throughput.

For gaming, the record includes no game scores. The processor's gaming potential would be tied first to the 4.30 GHz boost clock and second to the Arc Xe-LPG 64EU integrated GPU for graphics without a discrete card. Neither of these can be converted into a frame-rate estimate from this data.

The 50th percentile all-CPU rank and the absence of nearest-rival entries mean the 125UL is not positioned by this record as a high-end part. It is best considered by users who need the specific combination of Intel Socket 1851, low 15 W TDP, 12 cores, and integrated graphics in a single active desktop product. Users who need exact performance comparisons against named alternatives should note that such comparisons are not available in the benchmark fields of this record.

Power and Thermals

The TDP is 15 W. This is the only power-related figure in the record and it places the Core Ultra 5 125UL in the low-power desktop class. The processor is built on Intel's 7 nm process, and the architecture is Meteor Lake-PS.

The combination of a 15 W TDP and desktop Socket 1851 means the cooling requirement should be modest; nothing in the data implies a large cooling solution. A cooler that matches the low-power desktop segment and fits Socket 1851 is the appropriate tier.

The base clock of 1.30 GHz and boost clock of 4.30 GHz define the frequency envelope within that 15 W design point, but the record does not list sustained power limits or thermal throttling behavior. The production status is Active, so the part remains available in the current product line. For users assessing cooling, the 15 W TDP is the decisive thermal figure. Any cooling plan would also need to respect the physical Socket 1851 mounting, which is the socket listed in the record.

Single-Thread vs Multi-Thread Behavior

Single-thread behavior is represented by the 4.30 GHz boost clock and the per-core L1 cache of 112 KB. Multi-thread behavior is represented by the 12-core/14-thread count, the per-core L2 cache of 2 MB, and the shared L3 cache of 12 MB.

The record gives no per-core turbo table, so the number of cores that can actually run at 4.30 GHz is unspecified. It also gives no all-core sustained clock. The 14-thread count over 12 cores means the scheduler has more logical threads than physical cores, which can help when parallel tasks outnumber the physical cores.

Workloads that depend mainly on one thread should look to the 4.30 GHz boost figure as the best-case frequency. Workloads that use many threads should look to 12 cores, 14 threads, and the 12 MB shared L3. The memory path also matters for multi-threaded activity: the dual-channel DDR5 bus has a listed bandwidth of 89.6 GB/s.

Because no benchmark scores are recorded, the data cannot express how quickly single-threaded or multi-threaded workloads complete, nor can it provide a measured speedup ratio between those two modes. What the data does show is a wide base-to-boost clock gap, a core/thread count that favors parallelism, and a shared cache that is considerably larger than the per-core caches.
