Head-to-Head Benchmarks

The head-to-head data shows a dominant performance gap in favor of the Intel Core 9 273PE across nearly every test. The largest Intel advantage appears in Cinebench R23 single-core, where the Intel scores 4417 against the AMD's 2010, a delta of -54.5%. This means the AMD trails by more than half in that specific test.

In Cinebench R23 multi-core, the Intel scores 31288 while the AMD scores 16054, a delta of -48.7%. The Intel advantage is similarly pronounced in Cinebench R15 multi-core, with scores of 3153 versus 2457, a delta of -22.1%, and in Cinebench R15 single-core, with scores of 445 versus 220, a delta of -50.6%.

PassMark tests show consistent Intel wins. In floating point math, the Intel scores 107884 against the AMD's 52971, a delta of -50.9%. In find prime numbers, the Intel scores 203 against 84, a delta of -58.6%, the largest percentage gap in any recorded test. Physics performance shows the Intel at 3120 versus the AMD at 1337, a delta of -57.1%.

The Intel also leads in integer math with 139410 versus 86227, a delta of -38.1%. Data compression shows the Intel at 405885 versus 294298, a delta of -27.5%. Data encryption results show the Intel at 22719 versus 14925, a delta of -34.3%. Extended instructions show a smaller gap: the Intel at 24630 versus 20778, a delta of -15.6%. Random string sorting shows the Intel at 45098 versus 32344, a delta of -28.3%. The PassMark multithread test shows the Intel at 36810 versus 24779, a delta of -32.7%.

The single exception is the PassMark single-thread test, where the AMD wins with a score of 3955 against the Intel's 3650, a delta of 8.4%. This appears twice in the recorded data under slightly different test names, confirming the same result.

Specification Differences

The two processors differ in several recorded specification fields. The core count differs: the AMD has 8 cores, the Intel has 12. Thread counts differ similarly: 16 for AMD, 24 for Intel. Base clocks differ: the AMD runs at 2.00 GHz, the Intel at 2.30 GHz. Boost clocks differ: the AMD reaches 5.10 GHz, the Intel reaches 5.70 GHz.

TDP differs significantly: the AMD is rated at 28 watts, the Intel at 65 watts. Socket types differ: the AMD uses AMD Socket FP8, the Intel uses Intel Socket 1700. Process nodes differ: 4 nm for AMD, 10 nm for Intel. Foundries differ: TSMC for AMD, Intel for the Intel chip.

Where Each One Wins

The Intel Core 9 273PE wins in every multi-threaded and single-threaded Cinebench test. The recorded data shows the Intel ahead in all Cinebench R15 and R23 variants. The Intel also wins all PassMark tests except the single-thread test.

The AMD Ryzen AI 7 PRO 450 wins the PassMark single-thread test by 8.4%. This indicates the AMD has a per-core advantage in this specific workload, despite having fewer cores and a lower boost clock.

For multi-threaded workloads, the Intel's 12 cores and 24 threads provide a clear advantage over the AMD's 8 cores and 16 threads. The Cinebench R23 multi-core score of 31288 versus 16054 confirms this. The PassMark multithread score of 36810 versus 24779 also confirms this.

For single-threaded workloads, the results are mixed. The Cinebench R23 single-core test shows the Intel ahead by 54.5%, but the PassMark single-thread test shows the AMD ahead by 8.4%. The Cinebench R15 single-core test shows the Intel ahead by 50.6%.

The Intel wins the extended instructions test by 15.6%, which is the smallest margin among Intel wins. The largest Intel margins appear in find prime numbers (58.6%), physics (57.1%), and floating point math (50.9%).

The Verdict

The data clearly indicates the Intel Core 9 273PE is the stronger processor in the vast majority of recorded benchmarks. It wins 13 out of 15 head-to-head tests, including all Cinebench tests and all but one PassMark test. The Intel's average benchmark score of 49845 places it at the 90th percentile of all CPUs, while the AMD's average score of 37093 places it at the 85th percentile.

The Intel's nearest rivals include the AMD Ryzen AI Max+ 388 with a delta of 0.1%, the Intel Core i5-14600KF with a delta of 0.9%, the Intel Core i9-13980HX with a delta of -1.1%, and the AMD Ryzen AI 9 HX PRO 370 with a delta of -1.2%. The AMD's nearest rivals include the Intel Core i9-12900T with a delta of -0.1%, the AMD Ryzen 7 160 with a delta of -0.1%, the Intel Core i7-13700 with a delta of -0.1%, and the AMD Ryzen 7 7735H with a delta of -0.2%.

The AMD Ryzen AI 7 PRO 450 is a mobile processor with a 28-watt TDP, which explains its lower multi-threaded output compared to the 65-watt desktop Intel part. The AMD's win in PassMark single-thread shows it can match or exceed the Intel in lightly threaded scenarios, but the Intel's higher core count and larger cache produce decisive wins elsewhere.

Users prioritizing multi-threaded workloads, such as rendering or physics simulations, should choose the Intel Core 9 273PE based on the recorded data. Users prioritizing single-thread PassMark performance or mobile form factors should consider the AMD Ryzen AI 7 PRO 450. The Intel's launch MSRP of $549 is the only recorded pricing data.
