AMD Ryzen AI 7 450 vs Intel Core 7 253PQE Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in this comparison. Across all 15 head-to-head benchmark entries, the Intel Core 7 253PQE wins every single test. The AMD Ryzen AI 7 450 does not register a single victory in the database. The margins, however, vary considerably depending on the workload type.

The largest gap appears in Cinebench R23 single-core testing. Intel scores 4431 against AMD's 2038, a delta of -54%. That is a massive single-threaded advantage, more than doubling the AMD part's output. Cinebench R15 single-core shows a similar pattern: Intel at 446 versus AMD at 215, a -51.8% delta. These results indicate that the Intel chip holds a commanding lead in lightly threaded tasks that depend on raw per-core performance.

Multi-core performance also favors Intel, though the margin is somewhat smaller. In Cinebench R23 multi-core, Intel scores 31390 while AMD scores 18316, a -41.7% delta. Cinebench R15 multi-core shows Intel at 3163 versus AMD's 2713, a narrower -14.2% delta. The gap narrows significantly in this older test, suggesting the AMD processor handles the R15 workload more efficiently relative to its overall capability.

PassMark's integer math test shows Intel at 137795 versus AMD's 88531, a -35.8% delta. Floating point math shows an even larger separation: Intel at 105279, AMD at 54447, a -48.3% delta. The AMD chip delivers roughly half the floating-point throughput of the Intel part. Extended instructions follow suit, with Intel at 32390 and AMD at 22400, a -30.8% delta.

The prime number search test reveals the most dramatic ratio. Intel scores 206, AMD scores 89, a -56.8% delta. This workload, which is heavily dependent on integer operations and branch prediction, strongly favors the Intel architecture. Data compression tells a similar story: Intel at 487335 versus AMD's 315906, a -35.2% delta. Data encryption shows Intel at 25515 against AMD's 16247, a -36.3% delta.

Random string sorting has Intel at 54222 and AMD at 35648, a -34.3% delta. The physics test, which often reflects multi-core scaling, shows Intel at 2970 and AMD at 1578, a -46.9% delta. PassMark's multithread benchmark has Intel at 41656 versus AMD's 26350, a -36.7% delta.

The closest contest in the entire dataset is PassMark single-thread performance. Intel scores 4389, AMD scores 3901, a -11.1% delta. While Intel still wins, this is the only test where the AMD processor comes within striking distance. The database also records the same result under the passmark_singlethread field, confirming consistency.

Looking at average benchmark scores, Intel sits at 55919 while AMD sits at 39485. That places Intel roughly 41.6% higher on average. The percentile rankings reflect this: Intel lands in the 91st percentile of all CPUs, AMD in the 87th. Both are high performers, but Intel sits clearly above in the overall distribution.

The Verdict

The data shows a straightforward outcome. The Intel Core 7 253PQE wins every recorded benchmark, with particularly large margins in single-core and floating-point workloads. The AMD Ryzen AI 7 450 cannot claim a single victory in the head-to-head dataset.

For users prioritizing maximum performance in rendering, encryption, compression, or physics simulation, the Intel part is the clear choice from the numbers. The 54% lead in Cinebench R23 single-core means applications that rely on one or two fast threads will see substantial gains on Intel hardware.

The AMD Ryzen AI 7 450, however, should not be dismissed based on these losses alone. Its closest result, an 11.1% deficit in PassMark single-thread, shows it is competitive in basic single-threaded throughput. The chip also carries a much lower TDP of 28 watts against Intel's 125 watts, which the database records. For constrained thermal environments, that power difference may matter more than raw benchmark scores.

The database places Intel at the 91st percentile versus AMD's 87th. Intel's nearest rivals include the Intel Core i9-14900HX, with a delta of -0.2%, and the AMD Ryzen AI Max 390, with a delta of -0.6%. These are extremely close scores. AMD's nearest rivals include the AMD Ryzen 7 PRO 8840HS at -0.3% and the AMD Ryzen 7 9800X3D at -0.7%. The AMD part is effectively trading blows with those chips, while Intel sits in a slightly higher performance tier.

Architecture Differences

The two processors come from fundamentally different design approaches. The AMD Ryzen AI 7 450 uses the Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI 400 generation. It is built on a 4 nm process at TSMC. The Intel Core 7 253PQE uses the Bartlett Lake codename, part of the Core 7 generation, and is built on a 10 nm process at Intel.

Core counts differ significantly. AMD provides 8 cores and 16 threads. Intel provides 10 cores and 20 threads. That is two additional cores and four additional threads for the Intel part, which helps explain its multi-core wins.

Clock speeds also favor Intel. The AMD chip has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel chip has a base clock of 3.50 GHz and a boost clock of 5.70 GHz. Both base and boost clocks are higher on Intel, contributing to its single-core dominance.

Cache layouts are notably different. AMD uses 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 total. Intel uses 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Intel part has double the L2 per core and more than four times the total L3 cache. That large shared cache likely aids in workloads with repeated data access.

Memory support differs as well. AMD supports DDR5 and LPDDR5X. Intel supports DDR4 and DDR5. Both use dual-channel memory with identical recorded bandwidth of 89.6 GB/s. Both support ECC memory.

PCIe connectivity is a differentiator. AMD provides Gen 4 with 16 lanes from the CPU. Intel provides Gen 5 with 16 lanes from the CPU. The newer Gen 5 standard doubles the per-lane bandwidth, which matters for high-throughput devices.

Integrated graphics also differ. AMD uses the Radeon 860M. Intel uses UHD Graphics 770. The database does not record any graphics benchmark scores, so a direct comparison is not possible from the data.

The socket and market segment set these chips apart. AMD uses AMD Socket FP8 and targets the mobile segment. Intel uses Intel Socket 1700 and targets the desktop segment. The Intel chip also has a recorded launch MSRP of $409, while AMD's field is null.

The Intel part has a TDP of 125 watts. The AMD part has a TDP of 28 watts. That is a 97-watt difference in thermal design power.

Where Each One Wins

The Intel Core 7 253PQE wins in every measured category. The largest margins are in prime number finding (-56.8%), Cinebench R23 single-core (-54%), and Cinebench R15 single-core (-51.8%). These are heavily single-threaded or branch-intensive workloads. The Intel chip's higher boost clock of 5.70 GHz and larger cache give it a clear edge here.

Intel also dominates in floating-point math, leading by 48.3%. Physics simulation, which often stresses both integer and floating-point units, shows a 46.9% Intel advantage. Data encryption and compression both show Intel leads of roughly 35-36%. These are workloads where the 10-core, 20-thread configuration provides substantial parallel throughput.

The AMD Ryzen AI 7 450 has no benchmark wins in the recorded data. Its closest margin is the 11.1% deficit in PassMark single-thread, where it scores 3901 against Intel's 4389. That is the only test where the AMD chip comes within a small percentage of the Intel part.

The AMD chip's strongest relative showing is in Cinebench R15 multi-core, where its 2713 score trails Intel's 3163 by only 14.2%. This suggests the Zen 5 architecture handles this particular workload more efficiently than the newer R23 test, where the gap expands to 41.7%.

For power-sensitive deployments, the AMD part draws 28 watts against Intel's 125 watts. The database does not include efficiency ratios, but the raw TDP difference is substantial. In a thermally constrained chassis, the AMD chip will generate far less heat.

For raw performance, the Intel part is the clear winner in the database. Its 91st percentile ranking versus AMD's 87th, combined with its perfect 15-0 head-to-head record, leaves no ambiguity in the recorded scores. The AMD chip remains viable for scenarios where its significantly lower TDP and mobile socket are more critical than benchmark supremacy.
