AMD Ryzen AI 7 450 vs Intel Core 9 273PQE Comparison

Where Each One Wins

The recorded data shows a completely one-sided comparison in terms of benchmark wins. The Intel Core 9 273PQE wins every single head-to-head test in the database, taking all 15 measured workloads. The AMD Ryzen AI 7 450 does not win a single test, which means there is no workload category where the AMD part comes out ahead in the recorded measurements. This is not a close contest with trade-offs; it is a consistent sweep across rendering, encryption, compression, math operations, and single-threaded performance.

The Intel processor's largest advantage appears in single-threaded rendering workloads. In Cinebench R23 single-core, the Intel Core 9 273PQE scores 5532 against the AMD Ryzen AI 7 450's 2038, a delta of -63.2%. The Intel part also leads by -61.4% in Cinebench R15 single-core, scoring 557 versus 215. These gaps indicate a substantial per-thread performance advantage for the Intel chip, which matters for lightly threaded applications and response-time-sensitive workloads.

In multi-threaded rendering, the Intel Core 9 273PQE continues its dominance. Cinebench R23 multi-core shows the Intel part at 39190 versus the AMD part's 18316, a -53.3% delta. Cinebench R15 multi-core follows a similar pattern: Intel scores 3950, AMD scores 2713, a -31.3% delta. The multi-core margin is large but slightly narrower than the single-core margin, suggesting that the AMD chip's thread scaling partially compensates for its lower peak performance, though not enough to close the gap.

The PassMark suite reinforces the Intel lead across every category. Data compression shows Intel at 585752 versus AMD's 315906, a -46.1% delta. Data encryption favors Intel at 29636 against 16247, a -45.2% delta. Extended instructions favor Intel at 38743 versus 22400, a -42.2% delta. Floating point math shows Intel at 125546 against AMD's 54447, a -56.6% delta. Integer math favors Intel at 164629 versus 88531, a -46.2% delta. Prime number finding favors Intel at 198 versus 89, a -55.1% delta. Random string sorting favors Intel at 53167 versus 35648, a -33% delta. The PassMark multi-thread score favors Intel at 46107 versus 26350, a -42.9% delta, and the physics test favors Intel at 2754 versus 1578, a -42.7% delta.

The smallest relative gap appears in the PassMark single-thread test, where Intel scores 4573 versus AMD's 3901, a -14.7% delta. That is still a clear Intel win, but it is the closest margin in the entire dataset. This indicates that in purely single-threaded integer-style workloads, the AMD part is much closer to the Intel part than in any other category, though it still trails.

Architecture Differences

The two processors come from different manufacturers and use fundamentally different designs. The AMD Ryzen AI 7 450 uses the Zen 5 architecture, with the codename Gorgon Point, and belongs to the Ryzen AI 400 generation which combines Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC. The Intel Core 9 273PQE uses the codename Bartlett Lake and belongs to the Core 9 generation, built on a 10 nm process at Intel's own foundry.

The core and thread counts differ significantly. The AMD part has 8 cores and 16 threads, while the Intel part has 12 cores and 24 threads. That gives the Intel processor 50% more cores and 50% more threads, which directly contributes to its multi-threaded lead.

Clock speeds also differ. The AMD part has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel part has a base clock of 3.40 GHz and a boost clock of 5.90 GHz. The Intel part starts from a much higher base frequency and reaches a higher boost frequency, which explains its single-threaded advantages.

Cache configurations are notably different. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 total. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Intel processor has double the L2 per core and 4.5 times the total L3, which helps feed its higher core count.

The thermal design power differs substantially. The AMD Ryzen AI 7 450 has a TDP of 28 watts, while the Intel Core 9 273PQE has a TDP of 125 watts. This means the AMD part is designed for low-power mobile use, while the Intel part is a high-power desktop processor.

Memory support diverges as well. The AMD part supports DDR5 and LPDDR5X, while the Intel part supports DDR4 and DDR5. Both use dual-channel memory buses and both have a memory bandwidth of 89.6 GB/s. Both support ECC memory.

PCIe capabilities differ. The AMD part uses PCIe Gen 4 with 16 lanes from the CPU, while the Intel part uses PCIe Gen 5 with 16 lanes from the CPU. The Intel part has a newer PCIe generation.

The integrated graphics are also different. The AMD part uses Radeon 860M, while the Intel part uses UHD Graphics 770. The market segments differ: the AMD part is mobile, while the Intel part is desktop. The sockets differ as well: AMD uses Socket FP8, while Intel uses Socket 1700.

Head-to-Head Benchmarks

The Cinebench R23 multi-core test is the most dramatic single result. The Intel Core 9 273PQE scores 39190, which is more than double the AMD Ryzen AI 7 450's 18316. The -53.3% delta means the AMD part scores only 46.7% of the Intel part's result. This is the largest absolute point gap in the dataset.

Cinebench R23 single-core shows a similar relative gap. The Intel part scores 5532 against 2038 for the AMD part, a -63.2% delta. This is the largest percentage gap in any test, indicating that the Intel architecture has a massive per-core advantage in this rendering workload.

Cinebench R15 results follow the same direction but with smaller margins. Multi-core shows Intel at 3950 versus AMD at 2713, a -31.3% delta. Single-core shows Intel at 557 versus AMD at 215, a -61.4% delta. The R15 single-core margin is nearly as large as the R23 single-core margin.

PassMark integer math shows Intel at 164629 versus AMD at 88531, a -46.2% delta. This is a large absolute difference and indicates that general integer computation strongly favors the Intel part. Floating point math shows an even larger relative gap: Intel at 125546 versus AMD at 54447, a -56.6% delta.

Data compression shows Intel at 585752 versus AMD at 315906, a -46.1% delta. This workload benefits from the Intel part's larger cache and higher core count. Data encryption shows Intel at 29636 versus AMD at 16247, a -45.2% delta.

The PassMark single-thread test is the closest recorded result. Intel scores 4573, AMD scores 3901, a -14.7% delta. While still an Intel win, this margin is less than a quarter of the margin seen in Cinebench R23 single-core. This suggests that the AMD Zen 5 core is quite competitive in simple single-threaded integer operations, even though it loses decisively in more complex rendering workloads.

Prime number finding shows Intel at 198 versus AMD at 89, a -55.1% delta. Physics shows Intel at 2754 versus AMD at 1578, a -42.7% delta. Extended instructions show Intel at 38743 versus AMD at 22400, a -42.2% delta. Random string sorting shows Intel at 53167 versus AMD at 35648, a -33% delta.

The Verdict

The data is unambiguous: the Intel Core 9 273PQE is the faster processor in every recorded benchmark. For users who require maximum multi-threaded performance, the Intel part's 12 cores, 24 threads, 36 MB of L3 cache, and 125 watt TDP deliver results that the AMD Ryzen AI 7 450 cannot approach. In Cinebench R23 multi-core, the Intel part scores 39190 against 18316, more than double. In every PassMark workload, the Intel part leads by at least 14.7% and often by more than 45%.

The AMD Ryzen AI 7 450's only advantages lie in its power profile and platform positioning. With a 28 watt TDP, it is designed for mobile systems where power draw is a primary constraint. The Intel part's 125 watt TDP indicates a desktop-class design with much higher power consumption. The AMD part also uses a mobile socket (FP8) and a 4 nm TSMC process, which are typical for low-power laptop implementations.

For users building a desktop system and prioritizing raw performance, the Intel Core 9 273PQE is the clear choice from the recorded data. It wins every test, holds a higher 93rd percentile ranking versus the AMD part's 87th, and delivers a higher average benchmark score of 66099 versus 39485.
