Intel Core 9 273PTE vs Intel Core Ultra 7 256V Comparison

Where Each One Wins

The benchmark data splits cleanly by workload type. The Intel Core 9 273PTE wins 14 of 17 head-to-head tests, dominating multi-threaded, integer-heavy, and data-processing workloads. The Intel Core Ultra 7 256V wins only 3 tests, but those wins are concentrated in prime-number finding and single-thread PassMark tests, which points to its strength in light, latency-sensitive tasks.

For content creation and heavy parallel workloads, the Core 9 273PTE is the clear choice. Its Cinebench R23 multicore score of 20445 versus 10399 for the Ultra 7 256V represents a 96.6% advantage, nearly double the output. The Core 9 also leads in PassMark multithread (24054 vs 19530, a 23.2% gap), integer math (82411 vs 43358, a 90.1% gap), and data compression (258704 vs 184985, a 39.9% gap). These are tasks that scale with core count and thread count, and the Core 9's 12 cores and 24 threads provide the necessary parallelism.

The Ultra 7 256V wins in PassMark single-thread (4029 vs 3433, a 14.8% advantage) and PassMark find prime numbers (192 vs 142, a 26% advantage). These results suggest the Lunar Lake architecture has a per-core efficiency edge in certain scalar workloads, despite its lower boost clock of 4.80 GHz versus 5.50 GHz. The prime-number test, which is highly dependent on branch prediction and low-latency execution, shows the Ultra 7's architectural efficiency can overcome the Core 9's clock speed advantage.

In mixed workloads, the scores are closer. The Core 9 leads in floating-point math (60673 vs 58576, a 3.6% gap), extended instructions (15952 vs 15643, a 2% gap), and data encryption (14253 vs 13998, a 1.8% gap). These are small margins, indicating the Ultra 7 256V remains competitive in lightly threaded or vectorized tasks. The Core 9's wins in physics (1917 vs 1595, a 20.2% gap) and random string sorting (28973 vs 22481, a 28.9% gap) further cement its lead in structured computation.

Architecture Differences

The two processors represent fundamentally different Intel designs. The Core 9 273PTE uses the Bartlett Lake architecture, built on Intel's 10 nm process, while the Ultra 7 256V uses the Lunar Lake architecture, fabricated by TSMC on a 3 nm process. This process difference explains much of the efficiency gap: the Ultra 7 has a TDP of 17 watts, while the Core 9 is rated at 45 watts.

The core configurations differ sharply. The Core 9 273PTE has 12 cores and 24 threads, indicating Hyper-Threading support, while the Ultra 7 256V has 8 cores and 8 threads, meaning no SMT. The Core 9's cache hierarchy uses 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Ultra 7 uses larger per-core caches: 192 KB L1 and 2.5 MB L2, but only 12 MB shared L3. The Ultra 7's larger L1 and L2 caches likely contribute to its single-thread PassMark win, while the Core 9's much larger L3 pool supports its multi-threaded throughput.

Memory support also diverges. The Core 9 supports DDR4 and DDR5 with dual-channel memory and a rated bandwidth of 89.6 GB/s. The Ultra 7's memory support is listed as unknown and dependent on motherboard, though it also uses dual-channel memory. ECC memory is supported on the Core 9 but not on the Ultra 7. PCIe connectivity differs as well: the Core 9 provides 16 Gen 5 lanes, while the Ultra 7 provides only 4 Gen 5 lanes.

The integrated graphics differ significantly. The Core 9 uses UHD Graphics 730, a basic desktop solution, while the Ultra 7 uses Arc 140V, which is a more capable integrated GPU. The market segments reflect this: the Core 9 is a Desktop part on Intel Socket 1700, while the Ultra 7 is a Mobile part on Intel BGA 2833. Release dates are also far apart, with the Ultra 7 launching in September 2024 and the Core 9 in March 2026.

Head-to-Head Benchmarks

The largest single win for the Core 9 273PTE comes in Cinebench R23 multicore, where it scores 20445 against 10399, a 96.6% advantage. This is the clearest signal of the Core 9's multi-threading dominance. Cinebench R20 multicore shows a similar but smaller gap: 8586 vs 6958, a 23.4% lead. The R15 multicore test shows a 30.1% lead (2060 vs 1583.5). The scaling across Cinebench versions suggests the Core 9's advantage grows with longer, more complex rendering workloads.

PassMark integer math delivers the second-largest gap: 82411 vs 43358, a 90.1% lead for the Core 9. This test exercises ALU throughput, and the Core 9's 24 threads provide more parallel integer execution. Data compression shows a 39.9% lead (258704 vs 184985), and random string sorting shows a 28.9% lead (28973 vs 22481). These results confirm the Core 9 is substantially faster in data-processing tasks.

Single-core Cinebench results favor the Core 9 but by smaller margins. R15 single-core shows 290 vs 285.5, a 1.6% lead. R20 single-core shows 1212 vs 982, a 23.4% lead. R23 single-core shows 2886 vs 1877.5, a 53.7% lead. The R23 single-core gap is notable, as it indicates the Core 9's 5.50 GHz boost clock provides a significant advantage in sustained single-thread rendering. The Ultra 7's PassMark single-thread win (4029 vs 3433, a 14.8% lead) does not translate to Cinebench single-core wins, suggesting the two tests measure different aspects of single-thread performance.

The Ultra 7 256V wins only 3 tests total. Beyond PassMark single-thread and prime numbers, it wins no other head-to-head comparison. Its best relative showing in a losing effort is data encryption, where it trails by just 1.8% (13998 vs 14253). Extended instructions show a 2% gap (15643 vs 15952). These close margins indicate the Ultra 7's efficiency-oriented design keeps it competitive in moderately vectorized workloads despite the Core 9's higher core count.

The Verdict

The data points to the Intel Core 9 273PTE as the superior processor for multi-threaded and data-intensive workloads. Its 96.6% lead in Cinebench R23 multicore and 90.1% lead in integer math are decisive. The 24-thread configuration, 36 MB L3 cache, and 89.6 GB/s memory bandwidth give it a structural advantage that the Ultra 7 256V cannot overcome in parallel tasks. The Core 9 also holds a 23.4% lead in Cinebench R20 single-core, showing it is not merely a multi-thread specialist.

The Intel Core Ultra 7 256V is the efficiency-focused alternative. Its 17 W TDP versus 45 W, plus its 3 nm process node, make it suitable for mobile platforms where power draw is critical. Its wins in PassMark single-thread and prime-number finding indicate per-core efficiency in specific scalar workloads. However, its 8-core, 8-thread design and 12 MB L3 cache limit its throughput in rendering, compression, and math-heavy applications.

For desktop users running render farms, data compression pipelines, or compilation workloads, the Core 9 273PTE is the data-backed choice. For mobile users prioritizing battery life and light-thread responsiveness, the Ultra 7 256V has a role. The 82nd percentile ranking of the Core 9 versus the 75th percentile of the Ultra 7 confirms the overall performance hierarchy, but the two parts serve different market segments and power envelopes. The Core 9 wins on raw capability; the Ultra 7 wins on efficiency and specific single-thread tests.
