Intel Core 3 100UL vs Intel Core Ultra 3 205 Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 3 205 completely dominates the Intel Core 3 100UL in every recorded benchmark category. The Core 3 100UL has no benchmark scores in the database, while the Core Ultra 3 205 has scores across Cinebench R15, R20, R23, and Passmark tests. This means the comparison is one-sided: the Core Ultra 3 205 delivers measurable performance data, while the Core 3 100UL offers none for direct comparison.

The Core Ultra 3 205 achieves an average benchmark score of 31,473. Its percentile ranking of 82 indicates it outperforms 82% of all CPUs in the database. The Core 3 100UL sits at the 50th percentile with an average benchmark score of zero, though this reflects the absence of recorded data rather than actual performance parity.

In multi-core workloads, the Core Ultra 3 205 posts strong results. Cinebench R23 multicore reaches 19,856 points, while Cinebench R20 multicore lands at 8,339 points. The older Cinebench R15 multicore test shows 2,001 points. Passmark multithread scoring produces 26,167 points, and Passmark physics adds 2,016 points. These results position the chip in the upper half of the database, matching or slightly trailing a cluster of rivals. The nearest rivals include the Intel Core 7 240H with an average score of 31,483 and a delta of 0%, the AMD Ryzen 9 5980HX at 31,495 with a delta of -0.1%, the Intel Core Ultra 5 225H at 31,508 with a delta of -0.1%, and the Intel Core i5-13500 at 31,510 with a delta of -0.1%. The Core Ultra 3 205 sits within 0.1% of these chips, indicating near-identical average performance.

Single-core performance for the Core Ultra 3 205 is equally notable. Cinebench R23 singlecore records 2,803 points, Cinebench R20 singlecore reaches 1,177 points, and Cinebench R15 singlecore posts 282 points. Passmark singlethread scoring shows 4,575 points. These numbers confirm the boost clock of 4.90 GHz translates into competitive single-threaded throughput.

Specialized Passmark workloads reveal specific strengths. Data compression scores 260,651 points, a high figure that suggests strong integer throughput for compression tasks. Data encryption reaches 18,772 points. Extended instructions deliver 22,578 points, confirming robust SIMD and instruction-set support. Floating point math records 75,136 points, while integer math lands at 54,755 points. Prime number finding produces 268 points, and random string sorting hits 31,083 points.

The lack of any benchmark data for the Core 3 100UL means the head-to-head comparison cannot show a single instance where the older chip wins. The Core Ultra 3 205 holds every recorded metric. Its 8 cores and 8 threads, combined with a 4.90 GHz boost clock, deliver scores that place it among established mid-range and upper-mid-range processors. The Core 3 100UL, with 6 cores and 8 threads and a 4.50 GHz boost clock, likely trails in raw throughput, but the database offers no direct scores to quantify the gap.

The Verdict

The data supports a clear distinction between the two processors. The Intel Core Ultra 3 205 belongs in systems where measured performance matters. Its 82nd percentile ranking, average benchmark score of 31,473, and strong Cinebench and Passmark results place it among capable desktop CPUs. The 8 cores, 4.90 GHz boost clock, and DDR5-only memory support fit a modern desktop build.

The Intel Core 3 100UL offers no recorded benchmark scores, so the database cannot substantiate any performance claim for it. Its 50th percentile ranking and zero average score reflect missing data, not verified capability. The 6 cores, 4.50 GHz boost clock, and DDR4/DDR5 compatibility suggest it targets lower-power or legacy-platform scenarios, but the recorded information does not confirm its competitive position.

For any user relying on benchmark-verified performance, the Core Ultra 3 205 is the only choice supported by data. Its near-identical scores to the Intel Core 7 240H, AMD Ryzen 9 5980HX, Intel Core Ultra 5 225H, and Intel Core i5-13500 confirm it competes at a specific performance tier. The Core 3 100UL cannot be positioned against those chips without measurements.

Architecture Differences

The Core 3 100UL is built on Raptor Lake architecture with the codename Raptor Lake-PS, using a 10 nm process from Intel. The Core Ultra 3 205 uses Arrow Lake architecture with the codename Arrow Lake-S, built on a 3 nm process from TSMC. The manufacturing shift from Intel to TSMC marks a significant foundry change. The Core Ultra 3 205 contains 17,800 million transistors on a 243 mm² die, while the Core 3 100UL has no recorded transistor count or die size.

Cache hierarchies differ substantially. The Core 3 100UL provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The Core Ultra 3 205 provides 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 15 MB of shared L3 cache. Every level of cache is larger on the Core Ultra 3 205.

The Core Ultra 3 205 belongs to the Core Ultra Series 2 family and the Ultra 3 generation under Arrow Lake. The Core 3 100UL belongs to the Core 3 generation under Raptor Lake-PS. The Core 3 100UL has no series designation in the database. Both processors have locked multipliers, so neither supports unlocked overclocking. Neither supports ECC memory. Both target the desktop market segment and remain in active production.

Where Each One Wins

The Intel Core Ultra 3 205 wins every category with recorded data. Its 8 cores and 8 threads, combined with the 3 nm TSMC process, deliver benchmark scores across Cinebench R15, R20, and R23, as well as Passmark workloads. It is the clear pick for multi-threaded applications like video rendering, data compression, and physics simulation. Its Cinebench R23 multicore score of 19,856 and Passmark multithread score of 26,167 support this use case. Single-threaded work also favors the Core Ultra 3 205, with a Passmark singlethread score of 4,575 and a Cinebench R23 singlecore score of 2,803.

The Core Ultra 3 205 also wins on platform capabilities. PCIe Gen 5 with 20 lanes supports faster expansion devices, and the 102.4 GB/s memory bandwidth suits memory-intensive tasks. The larger L2 and L3 caches improve data locality. The 82nd percentile ranking confirms its position among the broader CPU landscape.

The Intel Core 3 100UL has no recorded benchmark wins. Its advantages are structural rather than measured: a 15-watt TDP suggests lower power consumption, and DDR4 support offers broader memory compatibility with existing platforms. The Intel Socket 1700 ecosystem is more established. However, the database contains no scores to quantify its performance, so any claim of a win in efficiency or compatibility rests on specification inference, not benchmark data. The Core Ultra 3 205 remains the only processor with verified performance results in this comparison.
