Where Each One Wins

The Intel Core 9 273PE dominates nearly every measurable workload category in the database. Across 17 head-to-head benchmark comparisons, it wins 15. Its largest advantages appear in integer math, where it scores 139410 against 39679 for the Ultra 5 228V, a 251.3% lead. Cinebench R23 multi-core shows a 215% advantage, and data compression shows a 133.4% margin (405885 versus 173924). These results indicate that the Core 9 273PE is the clear choice for compute-heavy tasks such as rendering, compilation, and data processing.

The Intel Core Ultra 5 228V wins only the PassMark single-thread test, scoring 3836 versus 3650 for the Core 9 273PE, a 4.8% edge. This is a narrow but genuine advantage in lightly threaded, latency-sensitive work. The Ultra 5 228V also has a much lower TDP of 17 watts versus 65 watts for the Core 9 273PE, which positions it as a more power-efficient option for mobile workloads despite its lower absolute performance.

Architecture Differences

The two processors come from different Intel product lines and use distinct designs. The Core 9 273PE is based on the Bartlett Lake architecture and belongs to the Core 9 generation. It is built on a 10 nm process at Intel's own foundry. The Ultra 5 228V uses the Lunar Lake architecture, part of the Core Ultra Series 2, and is fabricated on a 3 nm process by TSMC. The process node difference is substantial, with the Ultra 5 228V using a more advanced lithography.

Cache configurations also differ significantly. The Core 9 273PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Ultra 5 228V has 192 KB of L1 per core, 2.5 MB of L2 per core, and only 8 MB of shared L3. The Core 9 273PE therefore provides more than four times the total L3 capacity, which contributes to its large lead in multi-threaded workloads.

The Core 9 273PE uses the Intel Socket 1700 platform and is classified as a desktop part. The Ultra 5 228V uses Intel BGA 2833 and is a mobile processor. The integrated graphics also differ: the Core 9 273PE pairs with UHD Graphics 730, while the Ultra 5 228V includes Arc 130V. PCIe lane counts differ as well, with the Core 9 273PE offering 16 CPU lanes at Gen 5 and the Ultra 5 228V providing 4 lanes at Gen 5.

Specification Differences

The Core 9 273PE has 12 cores and 24 threads, while the Ultra 5 228V has 8 cores and 8 threads. Base clock speeds are 2.30 GHz for the Core 9 273PE and 2.10 GHz for the Ultra 5 228V. Boost clocks are 5.70 GHz and 4.50 GHz respectively. The Core 9 273PE has a TDP of 65 watts, while the Ultra 5 228V has a TDP of 17 watts, a difference of 48 watts.

Memory support differs: the Core 9 273PE supports DDR4 and DDR5, while the Ultra 5 228V's memory support is listed as dependent on the motherboard. The Core 9 273PE has a memory bandwidth of 89.6 GB/s, while the Ultra 5 228V has no recorded bandwidth figure. ECC memory is supported on the Core 9 273PE but not on the Ultra 5 228V.

The Core 9 273PE has a launch MSRP of $549. The Ultra 5 228V has no recorded launch MSRP in the database. The Core 9 273PE was released on 2026-03-08, while the Ultra 5 228V was released on 2024-09-23. Both processors have locked multipliers and are currently marked as active in production.

Head-to-Head Benchmarks

The largest single benchmark gap between the two processors appears in PassMark integer math. The Core 9 273PE scores 139410, while the Ultra 5 228V scores 39679, giving the Core 9 273PE a 251.3% advantage. This is a particularly wide margin and suggests that the Core 9 273PE's higher core count and larger cache provide a substantial edge in arithmetic workloads.

Cinebench R23 multi-core shows a 215% lead for the Core 9 273PE, with scores of 31288 versus 9932. The gap narrows in Cinebench R20 multi-core to 102.4% (13140 versus 6491) and in Cinebench R15 multi-core to 109.9% (3153 versus 1502.5). Single-core Cinebench results follow a similar pattern: R23 shows a 151.3% advantage for the Core 9 273PE (4417 versus 1758), R20 shows 102.5% (1855 versus 916), and R15 shows 66.7% (445 versus 267).

PassMark data compression favors the Core 9 273PE by 133.4%, with scores of 405885 versus 173924. Data encryption shows a 74.3% advantage (22719 versus 13032). Floating-point math scores 107884 for the Core 9 273PE against 53310 for the Ultra 5 228V, a 102.4% lead. Multi-thread performance in PassMark shows a 102% difference (36810 versus 18227), while physics tests show 102.9% (3120 versus 1538). Random string sorting favors the Core 9 273PE by 112.2% (45098 versus 21254). Extended instructions show a 66.4% lead (24630 versus 14801), and prime number finding shows a 20.8% edge (203 versus 168).

The only win for the Ultra 5 228V is in PassMark single-thread performance, where it scores 3836 against 3650 for the Core 9 273PE. The 4.8% margin is modest but consistent across both recorded entries for that test.

The Verdict

The Intel Core 9 273PE is the stronger processor in essentially every performance category measured. It holds a 215% lead in Cinebench R23 multi-core, a 251.3% lead in PassMark integer math, and a 133.4% lead in data compression. Its 90th percentile ranking versus the 75th percentile for the Ultra 5 228V reflects this overall performance gap. The Core 9 273PE also offers ECC memory support, a higher memory bandwidth of 89.6 GB/s, and a larger 36 MB shared L3 cache.

The Intel Core Ultra 5 228V has one genuine strength: single-thread performance. Its PassMark score of 3836 beats the Core 9 273PE's 3650, a 4.8% advantage. It also uses a more advanced 3 nm process from TSMC and consumes only 17 watts, compared to 65 watts for the Core 9 273PE. For mobile systems where power draw is a primary constraint, the Ultra 5 228V is the more efficient choice. However, its 8 MB L3 cache, 8 threads, and lower clock speeds limit its multi-threaded capability.

The data indicates a clear split in intended use. The Core 9 273PE is a desktop processor designed for maximum throughput across multi-threaded workloads, with a 65-watt TDP and support for DDR4 and DDR5 memory. The Ultra 5 228V is a mobile processor built for efficiency, with a 17-watt TDP and a single-thread edge that makes it suitable for lighter, latency-sensitive tasks. The Core 9 273PE wins 15 of 17 head-to-head comparisons, and the two that go to the Ultra 5 228V are both the same single-thread test.
