Head-to-Head Benchmarks

The Cinebench R23 single-core test delivers the clearest separation. The Intel Core 9 273PE scores 4,417, and the Intel Core i7-14700HX scores 2,103, giving the desktop part a 110% lead. This result aligns with the boost clock difference of 5.70 GHz versus 5.50 GHz, but the magnitude suggests architectural efficiency differences beyond clock speed.

The Cinebench R23 multi-core test also favors the Core 9 273PE, with a score of 31,288 versus 24,595, a 27.2% advantage. This is notable because the i7-14700HX has 8 more cores and 4 more threads. The Core 9 273PE's higher L3 cache (36 MB versus 33 MB) and higher TDP (65 watts versus 55 watts) likely contribute to this sustained all-core performance.

Cinebench R15 multi-core goes the other way. The i7-14700HX scores 3,812 against 3,153 for the Core 9 273PE, a 17.3% lead. This older benchmark appears to favor the higher core count of the mobile part. In Cinebench R20 multi-core, the two are nearly tied: 13,140 for the Core 9 273PE and 13,059 for the i7-14700HX, a 0.6% edge for the desktop chip. The Cinebench R20 single-core test shows a 0.7% lead for the Core 9 273PE with 1,855 versus 1,843.

PassMark results show a clear workload split. The i7-14700HX wins data compression (438,539 versus 405,885, a 7.4% lead), data encryption (26,092 versus 22,719, a 12.9% lead), random string sorting (48,544 versus 45,098, a 7.1% lead), and single-thread tests (3,947 versus 3,650, a 7.5% lead). The Core 9 273PE wins extended instructions (24,630 versus 25,718, a 4.2% deficit for the i7-14700HX), find prime numbers (203 versus 165, a 23% lead), floating-point math (107,884 versus 93,836, a 15% lead), integer math (139,410 versus 131,296, a 6.2% lead), multithread (36,810 versus 36,566, a 0.7% lead), and physics (3,120 versus 2,252, a 38.5% lead).

The PassMark multithread result of 36,810 for the Core 9 273PE versus 36,566 for the i7-14700HX is the closest margin outside of the Cinebench R20 tests. The physics test shows the largest multi-core gap in favor of the Core 9 273PE after Cinebench R23, with a 38.5% difference.

The win count stands at 10 for the Core 9 273PE and 7 for the i7-14700HX. The average benchmark scores reflect this split: 49,845 for the Core 9 273PE and 45,953 for the i7-14700HX, a difference of 3,892 points. The Core 9 273PE's nearest rival, the AMD Ryzen AI Max+ 388, sits only 0.1% away with an average score of 49,796. The i7-14700HX's nearest rival, the AMD EPYC 7303, matches it exactly at 45,960.
