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

Head-to-Head Benchmarks

The benchmark results show a clear split: the AMD Ryzen 9 9955HX wins 13 of the 15 recorded comparisons, while the Intel Core 7 253PE takes only two, both in Cinebench single-core tests. The magnitude of the AMD advantage varies sharply by workload, and the Intel single-core wins are not trivial.

The largest gap appears in Cinebench R15 multi-core, where the AMD scores 5905 against Intel's 2507, a 135.5% difference. That is more than double the output. Cinebench R23 multi-core shows a smaller but still decisive 49.4% lead (37159 versus 24880). PassMark extended instructions deliver the biggest percentage delta at 165.7% (57946 versus 21806), followed by random string sorting at 137.6% (77890 versus 32777) and data compression at 115.8% (731998 versus 339133). Data encryption is close behind at 103% (37330 versus 18385), and prime number finding shows 108% (287 versus 138). Integer math runs 86.2% ahead (212598 versus 114158), while multi-thread performance is 91.9% higher (56171 versus 29271). Floating point math shows a 69% edge (136682 versus 80870), and physics tests indicate a 47.4% advantage (2720 versus 1845).

The Intel part's two wins are in Cinebench R15 single-core (354 versus 336, a 5.1% margin) and Cinebench R23 single-core (3512 versus 2174, a 38.1% margin). The R23 single-core result is notable: Intel leads by over a third, a far larger relative advantage than the R15 gap. However, PassMark single-thread tells a different story, with the AMD scoring 4393 versus 3955, an 11.1% lead. The two Cinebench single-core tests and the PassMark single-thread test do not agree on which processor is faster in single-threaded work. The data suggests the Cinebench R23 single-core result may reflect a specific workload or boost behavior that favors Intel, while the PassMark result points to AMD having the higher sustained single-thread throughput.

The average benchmark score reinforces the overall picture: AMD sits at 91199 versus Intel's 40557. The AMD part lands in the 96th percentile of all CPUs in the database, while the Intel part sits at the 87th percentile. The nearest rivals for AMD include the Intel Xeon 654 (0.5% higher average) and the AMD Ryzen AI Max+ 392 (0.7% higher), placing it in a performance tier well above the Intel Core 7 253PE, whose closest rivals are the Intel Core 5 223PE, Intel Core Ultra X7 368H, Intel Xeon 6357P, and AMD Ryzen 9 7940H, all within 0.3% of its average score.

Architecture Differences

The two processors come from fundamentally different design approaches. The AMD Ryzen 9 9955HX uses the Zen 5 architecture on a 4 nm TSMC process, part of the Fire Range family in the 9000 series. It packages 16 cores and 32 threads. The Intel Core 7 253PE uses Bartlett Lake on a 10 nm Intel process, with 10 cores and 20 threads. The node difference is substantial: TSMC's 4 nm process versus Intel's 10 nm process, and the transistor count reflects the scale, with AMD listing 16,630 million transistors across a dual-die design of 2x 70.6 mm². Intel does not report transistor count or die size in the database.

Cache organization also differs. Both use 80 KB of L1 per core, but the L2 allocation is 1 MB per core on the AMD and 2 MB per core on the Intel. The L3 cache is a shared 64 MB on the AMD versus 33 MB on the Intel. With fewer cores but double the L2 per core, the Intel part relies on faster per-core cache access, while the AMD part leans on a much larger shared L3 pool for its 16 cores.

Memory support shows a split in flexibility. The AMD supports DDR5 only, dual-channel, with 89.6 GB/s bandwidth. The Intel supports both DDR4 and DDR5, also dual-channel, with the same 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity differs: AMD provides Gen 5 with 28 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics are Radeon 610M on the AMD and UHD Graphics 730 on the Intel.

Socket and market placement diverge sharply. The AMD uses AMD Socket FL1 and is classified as a mobile part, released 2025-01-05. The Intel uses Intel Socket 1700 and is classified as a desktop part, with a later release date of 2026-03-08. The AMD has an unlocked multiplier; the Intel is locked. The AMD lists a part number of 100-000001028, while the Intel lists SA4QE. The Intel has a launch MSRP of $384. The AMD has no recorded launch MSRP. The TDP figures are 55 W for the AMD and 65 W for the Intel, although both list the same base clock of 2.50 GHz. Boost clocks are 5.40 GHz on the AMD and 5.50 GHz on the Intel.

The Verdict

The recorded data points to two different design targets. The AMD Ryzen 9 9955HX delivers dominant multi-threaded performance across the board, with Cinebench R23 multi-core 49.4% higher and PassMark multi-thread 91.9% higher than the Intel. It also wins the PassMark single-thread test by 11.1%, meaning its per-thread advantage is not limited to heavy parallel workloads. The 96th percentile ranking and an average benchmark score of 91199 place it in a class above the Intel part, which scores 40557 on average and ranks at the 87th percentile.

The Intel Core 7 253PE does show a meaningful single-core advantage in Cinebench R23, leading by 38.1%, and a smaller edge in Cinebench R15 single-core at 5.1%. For workloads that track those Cinebench single-core results, the Intel part is the faster choice. But the PassMark single-thread result counters that picture, with the AMD ahead by 11.1%. The Intel part also supports both DDR4 and DDR5 memory, giving platform flexibility that the AMD does not offer, and its 33 MB of shared L3 cache is supplemented by 2 MB of L2 per core.

The market segments differ as well: the AMD is a mobile processor on Socket FL1, while the Intel is a desktop processor on Socket 1700. The Intel launch MSRP is $384, and it is a locked multiplier part; the AMD has an unlocked multiplier and no recorded launch MSRP. The AMD carries a 55 W TDP versus 65 W for the Intel, and the AMD provides 28 PCIe Gen 5 lanes versus 16 on the Intel.

Where Each One Wins

The AMD Ryzen 9 9955HX wins every multi-threaded and throughput-oriented workload in the database. Cinebench R15 and R23 multi-core, PassMark multi-thread, integer math, floating point math, data compression, data encryption, extended instructions, prime number finding, random string sorting, and physics all favor the AMD by margins ranging from 47.4% to 165.7%. Its 16 cores and 32 threads, paired with 64 MB of shared L3 cache, support workloads that scale with core count. The 28 PCIe Gen 5 lanes also give it more headroom for high-bandwidth peripherals. The mobile segment classification and 55 W TDP suggest it targets high-performance laptops where multi-threaded throughput is the priority.

The Intel Core 7 253PE wins the two Cinebench single-core tests, with a particularly strong 38.1% margin in R23 single-core. That indicates an advantage in lightly threaded workloads that behave like Cinebench's single-core test. The 5.50 GHz boost clock, 2 MB of L2 per core, and 33 MB of shared L3 cache likely contribute to that result. The desktop market segment and Socket 1700 platform, along with support for both DDR4 and DDR5 memory, make it a flexible desktop option, though its 16 PCIe Gen 5 lanes are half the AMD's count. Its locked multiplier and launch MSRP of $384 define it as a fixed-spec desktop processor. For users whose primary workloads match Cinebench single-core behavior, the Intel part is the faster option; for everything else in the recorded data, the AMD leads.
