Intel Core 5 315 vs Intel Core Ultra 5 135UL Comparison

The Verdict

The recorded data positions the Intel Core 5 315 as the stronger performer of the two, with a complete benchmark suite and a 72nd percentile ranking among all CPUs. The Intel Core Ultra 5 135UL, by contrast, has no recorded benchmark scores, an average score of zero, and a 50th percentile ranking, meaning its actual compute capabilities are unmeasured in the database. For users selecting strictly on available data, the Core 5 315 is the only unit with verified performance results, and its nearest rivals include the AMD EPYC 9274F and Intel Core i7-9700, both within 0% delta of its average score, indicating it sits at a well-established performance tier. The Ultra 5 135UL, while offering more cores and threads on paper, cannot be assessed for workload throughput because no measurements exist for it. The data shows the Core 5 315 as the actionable choice for any application where a benchmark score matters, while the Ultra 5 135UL remains a specification-only option with unproven execution.

Architecture Differences

The two processors diverge fundamentally in their design blueprints. The Core 5 315 uses the Wildcat Lake codename, belongs to the Core 5 generation, and is fabricated on a 3 nm process node by Intel. Its silicon houses 6 cores and 6 threads, meaning no hyperthreading is present, and each core operates with a base clock of 1.50 GHz and a boost clock of 4.40 GHz. Cache allocation includes 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The integrated graphics are Intel Xe3 Graphics with 2 Xe units.

The Core Ultra 5 135UL, in contrast, uses the Meteor Lake architecture with the Meteor Lake-PS codename, belongs to the Core Ultra Series 1 generation, and is built on a 7 nm process node. It contains 12 cores and 14 threads, indicating a hybrid configuration with performance and efficiency cores, and its base clock is 1.60 GHz with the same 4.40 GHz boost. Cache is organized differently: 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3. Its graphics solution is Arc Xe-LPG with 64 execution units.

The process node difference is substantial: 3 nm versus 7 nm, which typically indicates a more advanced manufacturing technology for the Core 5 315. Thread count favors the Ultra 5 135UL with 14 threads versus 6, a 133% increase, but the lack of benchmark data prevents any conclusion about whether that translates to real-world gains. The Core 5 315 also uses Intel BGA 1516 socket, while the Ultra 5 135UL uses Intel Socket 1851, meaning they are not platform-compatible. The Core 5 315 is classified as a Mobile segment part, while the Ultra 5 135UL is a Desktop segment part, despite both having a 15 TDP. This TDP parity, combined with the clock speeds, suggests similar power envelopes, but the architectural choices for core counts and cache hierarchies reflect different design intents.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for these two processors. The Core 5 315 has a full suite of 17 recorded test scores, while the Core Ultra 5 135UL has zero recorded scores across any test. Consequently, no direct comparison can be made for specific workloads such as Cinebench R23 multi-core, where the Core 5 315 scores 12981, or Cinebench R23 single-core, where it scores 1832. The database records no wins for either processor in a head-to-head context, as the winsA and winsB fields are both zero. The only meaningful interpretation is that the Core 5 315’s scores are verifiable: in PassMark integer math it reaches 31690, in floating point math 42441, in data compression 146143, and in data encryption 11119. Its single-thread PassMark score is 4021, and its multithread score is 15272. The Ultra 5 135UL offers no numbers to compare against any of these figures. Benchmark results indicate that any claims about the Ultra 5 135UL’s performance would be speculative, which is why the database lists its average benchmark score as zero. For users who rely on measured outcomes, the Core 5 315 is the sole source of quantitative evidence, and its 72nd percentile placement among all CPUs, with rivals like the AMD EPYC 9274F at an average score of 18189 and the Intel Core i7-9700 at 18180, places it in a well-known performance bracket. The Ultra 5 135UL’s 50th percentile, with no rivals listed, offers no comparable context.

Specification Differences

The specification sheets reveal several divergences beyond core counts and process nodes. Memory support differs: the Core 5 315 supports DDR5 and LPDDR5X, while the Core Ultra 5 135UL supports DDR5, with the latter’s support depending on the motherboard. Memory bus configuration is single-channel for the Core 5 315 versus dual-channel for the Ultra 5 135UL, which directly affects memory bandwidth: 59.7 GB/s for the Core 5 315 versus 89.6 GB/s for the Ultra 5 135UL, a 50% advantage for the latter. PCIe lanes also differ: the Core 5 315 provides Gen 4 with 6 lanes (CPU only), while the Ultra 5 135UL provides Gen 4 with 8 lanes (CPU only). Neither supports ECC memory. Both are locked multipliers. The release dates are not identical: the Core 5 315 has a release date of 2026-04-15, while the Ultra 5 135UL has a release date of 2024-04-07. The launch MSRP for the Core 5 315 is $340, and for the Ultra 5 135UL it is $331. Part numbers are SAEFC and SRN97 respectively. The production status for both is Active. The Ultra 5 135UL’s integrated graphics, Arc Xe-LPG with 64EU, is a different implementation from the Core 5 315’s Xe3 Graphics with 2 Xe units, indicating a higher execution unit count on the Ultra part. Cache structure is the most divergent field: the Core 5 315 has a small L2 of 2.5 MB total, while the Ultra 5 135UL has 2 MB per core, which for 12 cores could total significantly more, and the L3 doubles from 6 MB to 12 MB shared. The Core 5 315’s L1 is listed as 192 KB total, whereas the Ultra 5 135UL lists 112 KB per core. These cache differences suggest the Ultra 5 135UL is designed for higher data throughput per core, but without benchmarks, that remains a structural observation rather than a performance conclusion.
