AMD Ryzen 9 9955HX vs Intel Core 7 253PQE Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall winner in the AMD Ryzen 9 9955HX, which takes 12 of the 15 recorded head-to-head tests. The most decisive victory comes in Cinebench R15 multi-core, where the AMD scores 5905 against the Intel Core 7 253PQE's 3163, a massive 86.7% lead. That gap shrinks considerably in Cinebench R23 multi-core, but the AMD still wins by 18.4%, posting 37159 versus 31390.

The AMD also dominates the Passmark suite in nearly every compute-heavy task. Data compression shows a 50.2% advantage (731998 vs 487335), while extended instructions deliver a 78.9% lead (57946 vs 32390). Integer math favors the AMD by 54.3% (212598 vs 137795), and floating point math by 29.8% (136682 vs 105279). Data encryption is another strong AMD win at 46.3% (37330 vs 25515). Prime number finding, a test sensitive to core count and memory latency, goes to the AMD by 39.3% (287 vs 206). Random string sorting also favors the AMD, with a 43.7% edge (77890 vs 54222). The multi-thread Passmark score confirms the pattern: 56171 for AMD versus 41656 for Intel, a 34.8% difference.

The Intel Core 7 253PQE does have its victories, and they are concentrated where single-core speed dominates. In Cinebench R15 single-core, Intel wins by 24.7% (446 vs 336). The R23 single-core result is even more lopsided: Intel scores 4431 against 2174, a 50.9% advantage. The third Intel win comes in Passmark physics, where it posts 2970 versus 2720, an 8.4% lead. That physics result is interesting because it uses a limited thread count, so the higher per-core performance of the Intel chip shows through.

The single-thread Passmark scores are effectively a tie. The AMD edges ahead by 0.1% with 4393 versus 4389, which is within measurement noise. This suggests that for pure single-threaded integer workloads, the two processors are near-identical, despite the large discrepancies in Cinebench single-core results.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 9955HX uses the Zen 5 architecture on a 4 nm TSMC process, with the Fire Range codename. It belongs to the 9000 series and the Ryzen 9 generation. The chip integrates 16 cores and 32 threads, built from 16,630 million transistors across a dual-die layout with each die measuring 70.6 mm². The Intel Core 7 253PQE, by contrast, uses the Bartlett Lake codename on Intel's 10 nm process, with 10 cores and 20 threads. No transistor count or die size is recorded for the Intel part.

Cache layouts differ significantly. The AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and a shared 64 MB L3. The Intel also has 80 KB of L1 per core but doubles the L2 to 2 MB per core, while its shared L3 is 33 MB. The larger L3 on the AMD helps multi-threaded workloads that reuse shared data, while the larger per-core L2 on Intel benefits single-threaded latency-sensitive tasks.

Memory support splits as well. The AMD supports DDR5 only, while the Intel supports both DDR4 and DDR5. Both use dual-channel memory buses, and both record the same memory bandwidth figure of 89.6 GB/s. Both support ECC memory. PCIe lanes differ: the AMD offers Gen 5 with 28 CPU lanes, while the Intel offers Gen 5 with 16 CPU lanes.

The integrated graphics also differ. The AMD uses Radeon 610M, while Intel uses UHD Graphics 770. The AMD is an unlocked multiplier part, while the Intel is locked. The AMD targets the mobile segment with a 55 TDP, whereas the Intel is a desktop part with a 125 TDP. The AMD uses Socket FL1, and the Intel uses Socket 1700. The AMD was released on 2025-01-05, while the Intel's release date is listed as 2026-03-08.

Where Each One Wins

The AMD Ryzen 9 9955HX is the clear choice for heavily threaded workloads. Its 16 cores and 32 threads, combined with the large 64 MB L3 cache, produce decisive wins in multi-core rendering, data compression, encryption, integer math, floating point math, and extended instruction processing. The Cinebench R15 multi-core result, with an 86.7% lead, is the strongest single indicator that the AMD is built for parallel compute. The 18.4% lead in Cinebench R23 multi-core reinforces this, as does the 34.8% lead in Passmark multi-thread. Any workload that scales across many cores will favor the AMD.

The Intel Core 7 253PQE wins where single-core performance and lower thread counts matter. The Cinebench R23 single-core score shows a 50.9% advantage, and the R15 single-core shows a 24.7% lead. These are large margins, indicating that the Intel's higher boost clock of 5.70 GHz versus 5.40 GHz, coupled with its 10 nm process and larger L2 cache, delivers superior per-thread speed. The Passmark physics win of 8.4% is consistent with this, as physics simulations often use a modest number of threads and benefit from higher clock speeds.

The single-thread Passmark score being a near tie at 0.1% difference suggests that the AMD's Zen 5 architecture closes much of the gap in integer-heavy single-thread work, even if Cinebench shows a different picture. The Intel also has a notable advantage in the Cinebench R20 single-core test, where it scores 1861, though no comparable AMD R20 score is in the database for a direct comparison.

The Verdict

The data points to a straightforward choice for most workloads: the AMD Ryzen 9 9955HX is the stronger processor overall. It wins 12 of 15 benchmark comparisons, and its average benchmark score of 91199 places it in the 96th percentile of all CPUs. The Intel Core 7 253PQE, with an average score of 55919, sits in the 91st percentile. The AMD's nearest rivals include the Intel Xeon 654 at a 0.5% higher score and the AMD Ryzen AI Max+ 392 at 0.7% higher, while the Intel's nearest rivals are all within 1.1% of its score, including the Intel Core i9-14900HX at -0.2% and the AMD Ryzen AI Max 390 at -0.6%.

For users running multi-threaded applications, rendering, compilation, data processing, or any workload that uses more than a few cores, the AMD delivers substantially higher throughput. The 86.7% lead in Cinebench R15 multi-core and the 50.2% lead in data compression are not marginal differences; they represent a different performance class. The AMD also carries a much lower TDP of 55 versus 125, which is notable even though the AMD targets mobile and the Intel targets desktop.

The Intel Core 7 253PQE is the better option only when single-core performance is the absolute priority and multi-threaded performance is secondary. The 50.9% lead in Cinebench R23 single-core is a real advantage for lightly threaded applications, legacy software, or tasks that cannot use many cores. Its higher base clock of 3.50 GHz versus 2.50 GHz also helps in bursty workloads that do not sustain high thread counts.

The near-tie in Passmark single-thread scores (4393 vs 4389, a 0.1% difference) tempers the Intel's single-core advantage, suggesting that real-world single-thread integer performance is closer than Cinebench indicates. Still, the Intel's wins in R15 single-core, R23 single-core, and Passmark physics are consistent.

The specification differences reinforce the performance split. The AMD uses a 4 nm process with 16,630 million transistors, while the Intel uses a 10 nm process with no recorded transistor count. The AMD has 28 PCIe Gen 5 lanes versus 16 on the Intel. The AMD is unlocked, while the Intel is locked. The AMD supports only DDR5, while the Intel supports both DDR4 and DDR5. The Intel has a later release date and carries a launch MSRP of $409.

Given the data, the AMD Ryzen 9 9955HX is the better all-around processor for anyone who can use its 16 cores. The Intel Core 7 253PQE serves a narrower role: those who need the fastest possible single-threaded response and do not require high multi-thread throughput. The benchmark results do not show the Intel catching the AMD in any multi-threaded test, and the AMD does not match the Intel in the two single-core Cinebench tests. The choice rests on which workload profile matches the user's needs.
