The Core Ultra 7 265K also holds a commanding position relative to its nearest rivals in the database. Its average score of 70,879 sits 1% above the Intel Core i7-14700KF and 1.3% above the AMD Ryzen 7 9700F. It trails the Intel Xeon 6511P by 0.2% and the Intel Xeon Platinum 8270 by 0.7%. The Core 9 273PTE, by contrast, sits within 0.5% of its nearest competitors. It runs 0.2% above the Intel Core i7-12700F and the AMD Ryzen 9 8945HS, 0.4% above the Intel Core i7-13700TE, and 0.5% below the Intel Core i7-12650HX.

Where Each One Wins

The Core Ultra 7 265K wins across nearly every measured category. Its strengths concentrate in heavily parallel workloads: Cinebench multicore tests, PassMark multithread, data compression, encryption, extended instructions, prime number finding, floating point math, integer math, physics simulation, and random string sorting. The data indicates that this processor delivers substantially higher throughput in tasks that scale with core count and instruction-level parallelism.

The Core 9 273PTE wins in exactly one recorded benchmark: Cinebench R23 singlecore. Its score of 2,886 exceeds the Core Ultra 7 265K's 2,020 by 42.9%. This single result does not indicate broad single-thread superiority, because the Core Ultra 7 265K wins the other three single-thread tests in the database. The Cinebench R23 singlecore result stands as an isolated data point, possibly reflecting workload-specific behavior in that particular renderer.

For workloads that rely on single-threaded Cinebench R23 performance specifically, the Core 9 273PTE holds an edge. For everything else in the recorded data, the Core Ultra 7 265K delivers higher scores. The PassMark singlethread result corroborates this: the Core Ultra 7 265K leads by 30.3%, and the same margin appears in PassMark single thread. The Core 9 273PTE's 82nd percentile ranking and 31,143 average score place it in a different performance class entirely, closer to mid-range desktop and mobile parts from earlier generations.

Specification Differences

The two processors differ across nearly every physical and electrical specification. The Core Ultra 7 265K uses 20 cores and 20 threads, while the Core 9 273PTE uses 12 cores and 24 threads. The Core 9 273PTE thus supports hyperthreading, giving it more threads than cores, while the Core Ultra 7 265K runs one thread per core.

Base clocks differ substantially. The Core 9 273PTE has a base clock of 1.40 GHz, while the Core Ultra 7 265K runs at 3.90 GHz. Both boost to 5.50 GHz. Thermal design power differs by a wide margin: the Core 9 273PTE is rated at 45 watts, and the Core Ultra 7 265K at 125 watts.

Sockets are incompatible. The Core 9 273PTE uses Intel Socket 1700, while the Core Ultra 7 265K uses Intel Socket 1851. Memory support also differs: the Core 9 273PTE supports DDR4 and DDR5, while the Core Ultra 7 265K supports DDR5 only. Both use dual-channel memory buses, but peak bandwidth differs: 89.6 GB/s for the Core 9 273PTE versus 102.4 GB/s for the Core Ultra 7 265K.

PCIe lane counts differ. The Core 9 273PTE provides Gen 5 with 16 lanes, while the Core Ultra 7 265K provides Gen 5 with 20 lanes. Integrated graphics differ as well: the Core 9 273PTE uses UHD Graphics 730, while the Core Ultra 7 265K uses Arc Xe-LPG Graphics 64EU. The multiplier is locked on the Core 9 273PTE and unlocked on the Core Ultra 7 265K. The Core 9 273PTE launched with an MSRP of $549, and the Core Ultra 7 265K launched with an MSRP of $394.

Architecture Differences

The two processors come from different architectural lineages. The Core 9 273PTE is a Bartlett Lake part, and the Core Ultra 7 265K is an Arrow Lake-S part. The Core 9 273PTE belongs to the Core 9 generation, while the Core Ultra 7 265K belongs to the Core Ultra Series 2 and the Ultra 7 generation.

Process nodes and foundries differ. The Core 9 273PTE is fabricated on a 10 nm process at Intel. The Core Ultra 7 265K uses a 3 nm process at TSMC. The Core Ultra 7 265K has a published transistor count of 17,800 million and a die size of 243 mm². The Core 9 273PTE has no transistor or die size data in the database.

Cache structures differ across all levels. The Core 9 273PTE has 80 KB of L1 cache per core, 2 MB of L2 per core, and 36 MB of shared L3. The Core Ultra 7 265K has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The larger L3 on the Core 9 273PTE does not compensate for the lower core count in the recorded benchmarks.

Release timing differs by roughly a year and a half. The Core Ultra 7 265K was released on 2024-10-23, and the Core 9 273PTE on 2026-03-08. Both are listed as Active in production status. Both support ECC memory. Both target the desktop market segment. The part numbers differ: SA4QJ for the Core 9 273PTE and SRQCW for the Core Ultra 7 265K.

The Verdict

The recorded data directs a straightforward choice. The Intel Core Ultra 7 265K outperforms the Intel Core 9 273PTE in 16 of 17 benchmarks, with wins in every multicore test, every PassMark workload, and three of four single-thread tests. Its average score of 70,879 versus 31,143 places it in a different performance tier, and its 94th percentile ranking confirms that position. The Core 9 273PTE's single Cinebench R23 singlecore win, while notable at 42.9% ahead, does not offset the Core Ultra 7 265K's advantages elsewhere.

Buyers who need maximum throughput in rendering, compression, encryption, physics, or general multithreaded work should select the Core Ultra 7 265K. It also offers a higher memory bandwidth of 102.4 GB/s, more PCIe lanes at 20, a 3 nm process, an unlocked multiplier, and a lower launch MSRP of $394 against $549. The Core 9 273PTE suits a narrower set of use cases: those specifically targeting Cinebench R23 singlecore performance, systems limited to Intel Socket 1700, or builds requiring DDR4 support. Its 45 watt TDP and dual memory support (DDR4 and DDR5) may fit constrained platforms, but the benchmark data shows a substantial performance gap in nearly every measured workload. The Core Ultra 7 265K is the stronger processor across the database's recorded metrics.
