Across all recorded benchmarks, the Core Ultra 5 245 wins 17 out of 17 comparisons.

Architecture Differences

The two processors come from entirely different design lineages. The Intel Core 9 273PTE uses the Bartlett Lake architecture, built on a 10 nm process by Intel, while the Intel Core Ultra 5 245 uses the Arrow Lake architecture, built on a 3 nm process by TSMC. The Core Ultra 5 245 also carries a transistor count of 17,800 million on a 243 mm² die, while the Core 9 273PTE has no recorded transistor or die size data. This process advantage is a major factor in the performance gap.

The core configurations differ significantly. The Core 9 273PTE has 12 cores and 24 threads, indicating hyper-threading support. The Core Ultra 5 245 has 14 cores but only 14 threads, meaning it lacks hyper-threading. Despite having fewer threads, the Core Ultra 5 245 still wins all multi-threaded tests, suggesting its individual cores are substantially more efficient. The Core Ultra 5 245 also has a higher base clock of 3.50 GHz versus 1.40 GHz, and a boost clock of 5.10 GHz versus 5.50 GHz. The Core 9 273PTE has a higher boost clock but a much lower base clock.

Cache hierarchies also differ. The Core 9 273PTE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The Core Ultra 5 245 has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The Core Ultra 5 245 has more per-core cache but less total L3 cache. Memory support differs as well: the Core 9 273PTE supports both DDR4 and DDR5, while the Core Ultra 5 245 supports only DDR5. The Core Ultra 5 245 has a higher memory bandwidth of 102.4 GB/s versus 89.6 GB/s. Both support ECC memory and use a dual-channel memory bus.

The integrated graphics differ substantially. The Core 9 273PTE uses UHD Graphics 730, while the Core Ultra 5 245 uses Arc Xe-LPG Graphics 64EU, which is a more modern GPU architecture. PCIe support also differs, with the Core 9 273PTE offering 16 Gen 5 lanes and the Core Ultra 5 245 offering 20 Gen 5 lanes. The sockets are different: Intel Socket 1700 for the Core 9 273PTE and Intel Socket 1851 for the Core Ultra 5 245.

The Verdict

The data indicates that the Intel Core Ultra 5 245 is the superior processor by a wide margin. Its percentile ranking of 90 versus 82 for the Core 9 273PTE confirms its position in the broader market. The average benchmark score of 48995 for the Core Ultra 5 245 is significantly higher than the 31143 for the Core 9 273PTE. The nearest rivals for the Core Ultra 5 245 include the AMD Ryzen 9 7900 (0.5% ahead) and the Intel Core i5-14600K (0.8% behind), while the Core 9 273PTE's nearest rivals include the Intel Core i7-12700F (0.2% ahead) and the Intel Core i7-12650HX (0.5% ahead). These comparisons place the Core Ultra 5 245 in a higher performance class.

The Core 9 273PTE does not win a single recorded benchmark against the Core Ultra 5 245. The smallest gap is 9.6% in integer math, while the largest is 61.1% in prime number finding. The Core 9 273PTE's higher boost clock of 5.50 GHz does not translate into a single-threaded win, as the Core Ultra 5 245 still leads by 21.9% in that test. The Core 9 273PTE's 24 threads versus 14 threads for the Core Ultra 5 245 also fails to provide a multi-threaded advantage. The data is unambiguous: the Core Ultra 5 245 is the faster processor for every workload recorded.
