Intel Core 9 273PQE vs Intel Core Ultra 5 245T Comparison

Head-to-Head Benchmarks

The head-to-head data shows a dominant result for the Intel Core 9 273PQE, which wins 16 of the 17 recorded comparisons. The margins are substantial across most workloads. In Cinebench R15 multicore, the 273PQE scores 3950 against 2641 for the Core Ultra 5 245T, a 49.6% advantage. The single-core R15 result is nearly identical in percentage terms, with the 273PQE at 557 versus 372, a 49.7% lead. These patterns repeat in Cinebench R20 and R23, where the multicore deltas are 49.5% and 49.5% respectively, and single-core deltas are 49.6% in both cases.

The PassMark suite reveals where the performance gap widens even further. Data compression shows the 273PQE at 585752 against 283812, a massive 106.4% delta. Integer math follows with 164629 versus 88676, an 85.7% lead. Extended instructions show a 75.5% gap (38743 to 22071), and random string sorting comes in at 52.2% (53167 to 34931). Multithread performance is 49.5% higher for the 273PQE, consistent with the Cinebench multicore results.

The only benchmark where the Core Ultra 5 245T wins is PassMark find prime numbers. The 245T scores 324, while the 273PQE scores 198, meaning the 245T is 38.9% ahead. This is a notable outlier given the overall trend, and it suggests a specific workload characteristic that favors the Arrow Lake architecture. The closest head-to-head margin is in PassMark single-thread, where the 273PQE leads by just 4.7% (4573 to 4367). Floating point math also shows a relatively modest gap of 15.7% (125546 to 108499), while physics testing shows a 20.9% difference (2754 to 2278).

Architecture Differences

The two processors come from fundamentally different design directions. The Intel Core 9 273PQE uses the Bartlett Lake codename on the Intel Socket 1700 platform, built on Intel's 10 nm process. It features 12 cores and 24 threads, with base clock at 3.40 GHz and boost clock at 5.90 GHz. The thermal design power is 125 W. The Core Ultra 5 245T, by contrast, is an Arrow Lake-S part on Intel Socket 1851, fabricated by TSMC on a 3 nm process. It has 14 cores but only 14 threads, with a 2.20 GHz base clock and 5.10 GHz boost clock, and a 65 W TDP.

The transistor counts and die sizes reflect the different approaches. The 245T carries 17,800 million transistors on a 243 mm² die, while the 273PQE has no transistor count or die size recorded in the database. The cache hierarchies diverge as well. The 273PQE has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The 245T offers 192 KB L1 per core, 3 MB L2 per core, but only 24 MB shared L3. Despite having fewer cores, the 273PQE's larger L3 cache and higher clocks appear to drive its benchmark dominance.

Memory support differs: the 273PQE supports both DDR4 and DDR5, while the 245T supports only DDR5. Both are dual-channel, but the 245T has a higher memory bandwidth rating at 102.4 GB/s versus 89.6 GB/s for the 273PQE. Both support ECC memory. PCIe lane counts also differ, with the 273PQE providing Gen 5 with 16 CPU lanes, while the 245T provides Gen 5 with 20 CPU lanes. Integrated graphics differ as well: the 273PQE uses UHD Graphics 770, while the 245T uses Arc Xe-LPG Graphics 64EU.

The release dates are separated by over a year. The 245T launched in January 2025, and the 273PQE followed in March 2026. Both are marked as Active production status and target the Desktop market segment. Neither has an unlocked multiplier. The part numbers are SA4Q9 for the 273PQE and SRVFF for the 245T. The 273PQE belongs to the Core 9 generation under Bartlett Lake, while the 245T is part of Core Ultra Series 2 under Arrow Lake.

Where Each One Wins

The benchmark data splits cleanly by workload type. The Intel Core 9 273PQE wins every rendering, compression, encryption, math, and multithread test in the database. Cinebench R15, R20, and R23 multicore scores all favor the 273PQE by roughly 49.5%, which indicates strong scaling across its 24 threads. The PassMark data compression result, with a 106.4% lead, suggests the 273PQE has a significant advantage in data-heavy tasks. Integer math at 85.7% ahead reinforces this pattern for compute-intensive operations.

The single-core results are closer, especially in PassMark single-thread where the gap is only 4.7%. This suggests that for lightly threaded applications, the difference narrows considerably. The boost clock advantage of the 273PQE (5.90 GHz versus 5.10 GHz) likely contributes to this edge, but the 245T's newer 3 nm process and higher per-core L1 and L2 caches keep it competitive in single-threaded scenarios.

The Core Ultra 5 245T's sole win in prime number finding is intriguing. The 38.9% margin in that test, despite losing most other workloads, points to a specific algorithmic advantage. Prime number finding often benefits from certain instruction paths or cache behaviors, and the 245T's larger L1 (192 KB per core) and L2 (3 MB per core) may play a role here. The 245T also wins in efficiency-oriented metrics by virtue of its 65 W TDP versus 125 W for the 273PQE, though the database records no direct power consumption benchmarks.

For floating point math, the 273PQE leads by 15.7%, which is smaller than the integer math gap. This implies the 245T's architecture handles floating-point operations relatively well despite its lower core count and thread count. The physics test shows a 20.9% lead for the 273PQE, and random string sorting shows a 52.2% lead, indicating memory-heavy operations favor the 273PQE's larger L3 cache.

The Verdict

The data indicates a clear performance hierarchy. The Intel Core 9 273PQE is the faster processor in the vast majority of recorded benchmarks, with an average benchmark score of 66099 compared to 38194 for the Core Ultra 5 245T. The 273PQE sits at the 93rd percentile among all CPUs, while the 245T sits at the 86th percentile. The nearest rivals for the 273PQE include the Intel Core Ultra 5 250KF Plus at 66159 (0.1% behind) and the AMD Ryzen 9 7950X3D at 65914 (0.3% ahead), placing it in a strong competitive tier. The 245T's nearest rivals include the AMD Ryzen 7 250 at 38221 (0.1% behind) and the Intel Core i5-13600KF at 38103 (0.2% ahead), a lower performance bracket.

For users prioritizing raw compute, rendering, and multithreaded workloads, the 273PQE is the choice based on the recorded data. The 24 threads and 5.90 GHz boost clock deliver consistently higher scores, with some workloads nearly doubling the 245T's output. For single-threaded tasks, the 273PQE still leads, but the margin is small enough that the 245T remains competitive. The 245T's 14 threads and lower clocks limit its multicore potential, but its 14 physical cores and newer process node give it a distinct advantage in the prime number test, which may indicate strength in certain integer-heavy or cache-sensitive algorithms.

The socket and platform differences are decisive for system planning. The 273PQE requires Intel Socket 1700 and supports DDR4 or DDR5, while the 245T requires Intel Socket 1851 and only supports DDR5. The 245T offers more PCIe lanes (20 versus 16) and higher memory bandwidth (102.4 GB/s versus 89.6 GB/s), which could benefit systems with multiple GPUs or high-speed storage. The 245T also has a lower TDP, which may influence cooling requirements, though the database records no thermal or power measurements.
