Intel Core 3 100UL vs Intel Core 7 253PE Comparison

Intel Core 3 100UL and Intel Core 7 253PE are both Socket 1700 desktop processors, but they occupy very different tiers of performance. The Core 3 100UL is a low-power 6-core Raptor Lake part, while the Core 7 253PE is a 10-core Bartlett Lake chip with higher clock speeds and a much larger cache. Our measurements show a clear performance gap, driven by core count, thread count, and clock speed differences.

Head-to-Head Benchmarks

The benchmark database includes extensive test results for the Intel Core 7 253PE, but no recorded scores for the Intel Core 3 100UL. This means the comparison is one-sided, but the data is still revealing. The Core 7 253PE delivers a Cinebench R23 multi-core score of 24880, which is a strong result for a desktop processor. Its single-core score in the same test is 3512.

For the Core 3 100UL, the absence of benchmark scores means we have no direct measurements. However, the specification data indicates a significant disadvantage. The Core 3 100UL has 6 cores and 8 threads, while the Core 7 253PE has 10 cores and 20 threads. The Core 3 100UL boosts to 4.50 GHz, but the Core 7 253PE boosts higher, to 5.50 GHz. The Core 7 253PE also has a much larger L3 cache, 33 MB shared versus 10 MB shared on the Core 3 100UL.

The Core 7 253PE scores 10449 in Cinebench R20 multi-core and 1475 in single-core. Its Cinebench R15 results are 2507 multi-core and 354 single-core. These numbers place the Core 7 253PE in the 87th percentile of all CPUs in the database, with an average benchmark score of 40557. The Core 3 100UL sits at the 50th percentile, with an average benchmark score of zero due to missing data.

PassMark tests for the Core 7 253PE show a multi-thread score of 29271, a single-thread score of 3955, and an integer math score of 114158. Floating point math comes in at 80870, and extended instructions score 21806. Data compression reaches 339133, while data encryption scores 18385. Prime number finding is much lower at 138, and random string sorting scores 32777. Physics simulation scores 1845.

Architecture Differences

The two CPUs use different core architectures. The Core 3 100UL is based on Raptor Lake, with the codename Raptor Lake-PS. The Core 7 253PE uses Bartlett Lake, which is a separate codename. Both are built on a 10 nm process at Intel, so the transistor density is the same.

Cache organization differs substantially. Each core on the Core 3 100UL has 80 KB of L1 cache and 1.25 MB of L2 cache. The Core 7 253PE also has 80 KB of L1 per core, but its L2 cache is larger at 2 MB per core. The shared L3 cache is 10 MB on the Core 3 100UL versus 33 MB on the Core 7 253PE. This larger cache hierarchy on the Core 7 253PE helps feed its more numerous cores.

Memory support is similar, both supporting DDR4 and DDR5 in a dual-channel configuration. The Core 7 253PE adds ECC memory support, which the Core 3 100UL lacks. The Core 7 253PE also has a higher memory bandwidth figure, 89.6 GB/s, which is not specified for the Core 3 100UL.

PCIe capabilities differ. The Core 3 100UL provides PCIe Gen 4 with 8 lanes (CPU only). The Core 7 253PE provides PCIe Gen 5 with 16 lanes (CPU only). This gives the Core 7 253PE more bandwidth for GPUs and NVMe storage.

Integrated graphics are different. The Core 3 100UL uses UHD Graphics 64EU. The Core 7 253PE uses UHD Graphics 730. Both are Intel integrated solutions, but the Core 7 253PE has a different graphics unit designation.

Specification Differences

The key specification differences between the two processors are clear from the data. The Core 7 253PE has 10 cores versus 6 cores on the Core 3 100UL. Thread counts are 20 versus 8. The base clock is 2.50 GHz on the Core 7 253PE versus 1.20 GHz on the Core 3 100UL. Boost clock is 5.50 GHz versus 4.50 GHz.

Thermal design power is very different. The Core 7 253PE has a TDP of 65 watts, while the Core 3 100UL has a TDP of 15 watts. This indicates the Core 3 100UL is designed for low-power operation, while the Core 7 253PE targets higher sustained performance.

Cache sizes differ as noted above: L2 cache is 1.25 MB per core on the Core 3 100UL versus 2 MB per core on the Core 7 253PE. L3 cache is 10 MB versus 33 MB. PCIe generation and lane count differ: Gen 4 with 8 lanes versus Gen 5 with 16 lanes. ECC memory support is present only on the Core 7 253PE. Memory bandwidth is listed only for the Core 7 253PE.

Part numbers differ. The Core 3 100UL has an unknown part number, while the Core 7 253PE has part number SA4QE. Neither processor has an unlocked multiplier. Both are listed as active production parts.

Where Each One Wins

The Core 7 253PE wins in every measurable performance category. Its multi-core performance is far superior due to 10 cores and 20 threads, which is 4 more cores and 12 more threads than the Core 3 100UL. The higher boost clock of 5.50 GHz also gives it a single-thread advantage over the 4.50 GHz Core 3 100UL. The larger 33 MB L3 cache and 2 MB per-core L2 cache improve data access patterns.

The Core 3 100UL wins on power efficiency. Its 15 watt TDP is much lower than the 65 watt TDP of the Core 7 253PE. This makes it suitable for low-power or compact systems where heat output and cooling requirements are minimal. The Core 3 100UL also has a lower base clock of 1.20 GHz, which helps manage power consumption during idle or light loads.

For ECC memory support, the Core 7 253PE is the only option. This makes it attractive for systems requiring error-correcting memory, such as small servers or workstation setups. The Core 3 100UL lacks ECC support entirely.

The Core 7 253PE also offers faster PCIe connectivity with Gen 5 and 16 lanes, versus Gen 4 and 8 lanes on the Core 3 100UL. This matters for high-bandwidth peripherals. The Core 3 100UL offers no PCIe advantage.

The Verdict

The data clearly shows the Intel Core 7 253PE is the superior processor. It has more cores, more threads, higher clock speeds, more cache, ECC memory support, faster PCIe, and higher memory bandwidth. Its benchmark scores are strong, placing it in the 87th percentile of all CPUs. The Core 7 253PE is appropriate for demanding multi-core workloads, content creation, and professional applications.

The Intel Core 3 100UL is a low-power part with a 15 watt TDP. It has no recorded benchmark scores, but its specifications suggest it is suitable for basic desktop tasks and energy-conscious builds. Its 6 cores and 8 threads are insufficient for heavy multi-threaded work compared to the Core 7 253PE.

Users needing maximum performance should choose the Core 7 253PE. Users prioritizing low power consumption or minimal cooling requirements may consider the Core 3 100UL, but they must accept significantly lower performance in every benchmark category. The 50th percentile ranking of the Core 3 100UL versus the 87th percentile of the Core 7 253PE summarizes the gap. The Core 7 253PE is the clear choice for performance-focused systems.
