Intel Core 9 273PTE vs Intel Core Ultra 7 270K Plus Comparison

The Intel Core 9 273PTE and Intel Core Ultra 7 270K Plus occupy very different positions in the desktop CPU landscape. The Core 9 273PTE is a 12-core, 24-thread processor on Intel Socket 1700, built on a 10 nm process and featuring 36 MB of shared L3 cache. The Core Ultra 7 270K Plus is a 24-core, 24-thread part on Intel Socket 1851, using a 3 nm process from TSMC with 36 MB of shared L3 cache as well. The benchmark data shows a clear and consistent performance gap, with the Core Ultra 7 270K Plus winning 16 of the 17 recorded head-to-head tests. The only exception is a single-core Cinebench R23 result, where the Core 9 273PTE takes the win. The average benchmark score reinforces the separation: the Core 9 273PTE sits at 31,143, while the Core Ultra 7 270K Plus reaches 93,785. The percentile rankings also differ sharply, with the Core 9 273PTE in the 82nd percentile of all CPUs and the Core Ultra 7 270K Plus in the 96th percentile.

Head-to-Head Benchmarks

The most dominant wins for the Intel Core Ultra 7 270K Plus come in multi-threaded and memory-heavy workloads. In Cinebench R15 multicore, the Core Ultra 7 270K Plus scores 6,656 against 2,060 for the Core 9 273PTE, a delta of -69.1%. That pattern holds in Cinebench R20 multicore, where the Core Ultra 7 270K Plus scores 24,461 versus 8,586, a -64.9% difference. Cinebench R23 multicore shows the same trend: 44,253 for the Core Ultra 7 270K Plus and 20,445 for the Core 9 273PTE, a -53.8% delta. The Core Ultra 7 270K Plus doubles or nearly doubles the Core 9 273PTE in every Cinebench multi-core test.

Single-core results are closer but still favor the Core Ultra 7 270K Plus in most cases. In Cinebench R15 single-core, the Core Ultra 7 270K Plus scores 354 versus 290, a -18.1% delta. Cinebench R20 single-core shows a much larger gap: 3,453 for the Core Ultra 7 270K Plus and 1,212 for the Core 9 273PTE, a -64.9% delta. The single exception to the Core Ultra 7 270K Plus sweep is Cinebench R23 single-core, where the Core 9 273PTE scores 2,886 against 2,439, a +18.3% delta. This indicates that in that specific test, the Core 9 273PTE holds a genuine advantage.

PassMark results also heavily favor the Core Ultra 7 270K Plus. In data compression, the Core Ultra 7 270K Plus scores 804,322 versus 258,704, a -67.8% delta. Data encryption shows 59,097 versus 14,253, a -75.9% delta. Extended instructions score 63,506 versus 15,952, a -74.9% delta. Find prime numbers delivers 615 versus 142, a -76.9% delta. Floating point math records 229,491 versus 60,673, a -73.6% delta. Integer math shows 175,986 versus 82,411, a -53.2% delta. The multithread PassMark test gives 68,574 versus 24,054, a -64.9% delta, and physics shows 4,064 versus 1,917, a -52.8% delta. Random string sorting scores 96,945 versus 28,973, a -70.1% delta. In single-thread PassMark tests, the Core Ultra 7 270K Plus scores 5,068 versus 3,433, a -32.3% delta.

The delta percentages consistently exceed 50% in most multi-threaded and specialized workloads, which indicates a fundamental throughput difference rather than a marginal one. The Core 9 273PTE only manages to beat the Core Ultra 7 270K Plus in one recorded test, and that win is limited to a single-core Cinebench R23 scenario.

The Verdict

The data points to the Intel Core Ultra 7 270K Plus as the stronger processor for almost all recorded workloads. It wins 16 out of 17 head-to-head tests, and its average benchmark score of 93,785 is roughly three times the 31,143 average of the Core 9 273PTE. The Core Ultra 7 270K Plus also lands in the 96th percentile of all CPUs, while the Core 9 273PTE sits in the 82nd percentile. The nearest rivals for the Core Ultra 7 270K Plus are server-class parts: the Intel Xeon 6520P with an average score of 93,786 and a 0% delta, the AMD EPYC 4564P at 95,183 with a -1.5% delta, the AMD EPYC 9175F at 95,615 with a -1.9% delta, and the AMD EPYC 4565P at 95,764 with a -2.1% delta. That places the Core Ultra 7 270K Plus in the same performance tier as those enterprise processors.

The Core 9 273PTE, by contrast, sits near much more modest competition. Its nearest rivals are the Intel Core i7-12700F with an average score of 31,081 and a 0.2% delta, the AMD Ryzen 9 8945HS at 31,074 with a 0.2% delta, the Intel Core i7-13700TE at 31,028 with a 0.4% delta, and the Intel Core i7-12650HX at 31,290 with a -0.5% delta. The Core 9 273PTE is effectively in the same class as those parts, which means it is not competitive with the Core Ultra 7 270K Plus in aggregate performance. The only scenario where the Core 9 273PTE takes the lead is Cinebench R23 single-core, where it beats the Core Ultra 7 270K Plus by 18.3%. For anyone choosing based on the recorded data, the Core Ultra 7 270K Plus is the clear pick for multi-threaded work, and it also wins most single-thread tests. The Core 9 273PTE is only preferable in the narrow case of Cinebench R23 single-core performance.

Where Each One Wins

The Intel Core Ultra 7 270K Plus wins in nearly every category covered by the recorded benchmarks. Multi-threaded workloads are its strongest territory, as shown by Cinebench R15, R20, and R23 multicore scores, where it leads by margins of 53.8% to 69.1%. PassMark multithread, physics, integer math, floating point math, and data compression all show the Core Ultra 7 270K Plus ahead by at least 52.8%. Data encryption, extended instructions, and find prime numbers also favor the Core Ultra 7 270K Plus by large margins, with deltas of 75.9%, 74.9%, and 76.9% respectively. Single-thread PassMark tests also go to the Core Ultra 7 270K Plus, with a 32.3% delta. The Core Ultra 7 270K Plus is also the only one of the two with an unlocked multiplier, which makes it the more flexible option for users who plan to adjust clocks.

The Intel Core 9 273PTE has one clear win: Cinebench R23 single-core, where it beats the Core Ultra 7 270K Plus by 18.3%. That result matters for workloads that rely heavily on that specific benchmark, but it does not carry over to other single-thread tests. In Cinebench R15 single-core and Cinebench R20 single-core, the Core Ultra 7 270K Plus wins. The Core 9 273PTE also has a much lower TDP at 45 W versus 125 W, which indicates it draws less power, though the recorded data does not include direct power consumption measurements. The Core 9 273PTE supports DDR4 memory, which the Core Ultra 7 270K Plus does not, and that could be relevant for users with existing DDR4 platforms. However, the Core Ultra 7 270K Plus has higher memory bandwidth, more PCIe lanes, a smaller process node, and a substantially higher average benchmark score. For users prioritizing raw throughput, the Core Ultra 7 270K Plus is the processor the data supports. For users who need a specific single-core Cinebench R23 result or prefer a lower-power part with DDR4 compatibility, the Core 9 273PTE has a narrow case.
