AMD Ryzen 7 8745HX vs Intel Core 7 253PQE Comparison

The AMD Ryzen 7 8745HX and the Intel Core 7 253PQE occupy different corners of the processor market, yet their benchmark results place them in a surprisingly close overall performance band. The AMD part, a mobile-focused 8-core chip from the Ryzen 8000 series, sits at the 92nd percentile against all CPUs in the database. The Intel part, a desktop-oriented 10-core chip from the Bartlett Lake generation, sits at the 91st percentile. Despite that near-identical overall ranking, the head-to-head measurements show a decisive split: the Intel Core 7 253PQE wins all 11 recorded benchmark comparisons, with margins ranging from a modest 11.6% to a dominant 43.4%. The AMD Ryzen 7 8745HX records zero wins in the direct comparison set. This analysis walks through the exact numbers, the architectural reasons for the gap, and the use cases where each processor still holds its ground.

Head-to-Head Benchmarks

The largest single delta appears in the PassMark physics test. The Intel Core 7 253PQE scores 2970, while the AMD Ryzen 7 8745HX scores 1681. That is a 43.4% advantage for Intel, the biggest gap in the entire comparison. Physics workloads often stress scheduling and raw core throughput, and the Intel chip’s 10 cores and 20 threads appear to provide a substantial edge here.

Floating-point math shows a similar pattern. Intel scores 105279, AMD scores 61972, a 41.1% deficit for the AMD part. This is the second-largest margin in the set. Floating-point performance matters for scientific simulations, certain rendering tasks, and financial modeling, so this gap is not trivial. Integer math follows with Intel at 137795 and AMD at 100328, a 27.2% difference. Integer workloads cover a broad swath of general-purpose computing, from database queries to code compilation, and the Intel chip leads clearly.

Data compression shows Intel at 487335 versus AMD at 363759, a 25.4% margin. Compression is heavily dependent on memory bandwidth and cache behavior, and the Intel chip’s 33 MB of shared L3 cache and 89.6 GB/s memory bandwidth likely contribute. Data encryption tells a similar story: Intel scores 25515, AMD scores 21840, a 14.4% difference. Encryption tests often stress the processor’s ability to handle AES instructions and other cryptographic operations, and Intel maintains its lead, though the margin is tighter here.

Extended instructions deliver Intel 32390 against AMD 27638, a 14.7% gap. Prime number finding, a common single-threaded stress test, shows Intel at 206 versus AMD at 159, a 22.8% margin. Random string sorting gives Intel 54222 and AMD 44494, a 17.9% difference. Multithreaded performance, measured by the PassMark multithread score, puts Intel at 41656 and AMD at 31517, a 24.3% advantage for Intel. The single-thread scores, which appear twice in the database under slightly different labels, both show Intel at 4389 and AMD at 3879, an 11.6% margin. That single-thread delta is the smallest of the set, but it still favors Intel across the board.

The overall average benchmark scores reflect this dominance. Intel’s average is 55919, while AMD’s is 60104. That seems contradictory at first glance, since AMD’s average is higher. The explanation lies in the different benchmark suites recorded for each chip. The AMD processor’s average includes its PassMark results only, which are strong across the board. The Intel processor’s average includes a set of Cinebench scores (R15, R20, R23) alongside the PassMark results, and those Cinebench numbers pull its average down relative to the head-to-head PassMark tests. The direct comparison set, however, uses only the identical tests, and there Intel wins every one. The database’s nearest-rival data places the AMD chip near the AMD Ryzen 9 7945HX (0% delta), the Intel Core i9-14900F (0.2% ahead), and the AMD Ryzen 9 7945HX3D (0.8% ahead). The Intel chip’s nearest rivals include the Intel Core i9-14900HX (0.2% behind) and the AMD Ryzen AI Max 390 (0.6% behind). Both chips compete with top-tier desktop and mobile parts from previous generations, which contextualizes their overall percentile rankings.

Architecture Differences

The two processors diverge sharply at the architectural level. The AMD Ryzen 7 8745HX uses Zen 4 architecture on the Dragon Range codename, built on a 5 nm process by TSMC. It packs 8 cores and 16 threads, a configuration typical of high-end mobile gaming laptops. The Intel Core 7 253PQE uses the Bartlett Lake codename, built on a 10 nm process by Intel’s own foundry, and offers 10 cores and 20 threads. That two-core, four-thread advantage directly explains many of the multithreaded benchmark wins.

Cache layouts differ as well. AMD provides 64 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Intel part has larger per-core L1 and L2 caches, plus a slightly larger L3 pool. For workloads that fit within those caches, Intel has a structural edge. The AMD chip does not offer any 3D V-Cache variant in this data, so that advantage is not present here.

Clock speeds matter in the single-thread tests. AMD lists a base clock of 3.60 GHz and a boost clock of 5.10 GHz. Intel lists a base clock of 3.50 GHz and a boost clock of 5.70 GHz. The Intel chip boosts 600 MHz higher, which aligns with its 11.6% single-thread win. The AMD chip has a slightly higher base clock, but that does not translate into a win in any recorded test.

Memory support presents another split. AMD supports DDR5 only, with dual-channel access and a recorded memory bandwidth of 83.2 GB/s. Intel supports both DDR4 and DDR5, also dual-channel, with a higher recorded memory bandwidth of 89.6 GB/s. That 6.4 GB/s bandwidth advantage, combined with the larger L3 cache, likely contributes to the Intel wins in data compression and random string sorting. Intel also supports ECC memory, while AMD does not, a meaningful factor for workstation reliability. PCIe lanes differ as well: AMD provides Gen 5 with 28 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The AMD part offers more PCIe connectivity for expansion, which matters for users attaching multiple GPUs or high-speed storage devices.

Integrated graphics also differ. AMD uses the Radeon 610M, while Intel uses UHD Graphics 770. Neither part is positioned as a graphics powerhouse, but the presence of any iGPU means both can drive displays without a discrete GPU. The AMD chip is unlocked for overclocking, while the Intel chip is locked. The AMD part targets the mobile segment with a 55 W TDP, while the Intel part targets the desktop segment with a 125 W TDP. That thermal and power envelope difference explains why the Intel chip can sustain higher boost clocks and more aggressive performance, but it also means the Intel chip requires a more substantial cooling solution and power delivery setup.

Where Each One Wins

The benchmark data shows a clean sweep for Intel in every direct comparison, so the “where each one wins” section is necessarily about qualitative strengths derived from the specification sheet, not from head-to-head test victories. The AMD Ryzen 7 8745HX wins on portability and platform flexibility. It is a mobile processor with a 55 W TDP, which means it belongs in laptops and compact systems where power draw and heat output are constrained. Its 28 PCIe Gen 5 lanes provide more expansion headroom than the Intel chip’s 16 lanes, which matters if the motherboard needs multiple NVMe drives or additional add-in cards. The unlocked multiplier allows tuning for users who want to extract extra performance within the thermal limits of their chassis. The AMD chip’s 8 cores and 16 threads are fewer than Intel’s, but the Zen 4 architecture on a 5 nm process demonstrates that a smaller transistor count can still compete in the same performance percentile.

The Intel Core 7 253PQE wins on raw compute across every measured workload. The 10 cores and 20 threads give it a structural advantage in heavily threaded applications such as video encoding, 3D rendering, and scientific number crunching. The 5.70 GHz boost clock gives it the edge in single-threaded tasks like web browsing, office productivity, and lightly threaded legacy software. The larger caches and higher memory bandwidth support data-intensive workloads. The ECC memory support makes it a candidate for error-sensitive tasks in data processing or server-like roles. The desktop Socket 1700 platform offers a wide ecosystem of motherboards and cooling options, though the 125 W TDP demands a capable cooler.

For users who prioritize battery life, low noise, or small form factors, the AMD part’s 55 W TDP is a clear advantage. For users who prioritize maximum throughput and do not care about power consumption, the Intel part’s benchmark margins are decisive. The database does not record any test where the AMD chip beats the Intel chip, so any recommendation for the AMD part must rest on non-benchmark factors: platform, power, and expansion.

The Verdict

The recorded data points to one unambiguous conclusion: the Intel Core 7 253PQE outperforms the AMD Ryzen 7 8745HX in every head-to-head benchmark test. The smallest Intel margin is 11.6% in single-thread performance, and the largest is 43.4% in physics. Multithreaded performance favors Intel by 24.3%. Floating-point math favors Intel by 41.1%. Data compression favors Intel by 25.4%. No test in the comparison set shows an AMD win. The Intel chip’s higher core count, larger caches, higher boost clock, and greater memory bandwidth all contribute to this sweep.

Users should pick the Intel Core 7 253PQE if their priority is maximum compute performance across a wide range of tasks, especially those that use many threads, heavy math, or large data sets. The desktop platform with Socket 1700 and ECC support suits workstation and content-creation environments. Users should pick the AMD Ryzen 7 8745HX if their priority is a mobile form factor, lower power draw, or broader PCIe expansion. The 55 W TDP makes it suitable for laptops and compact builds where the 125 W Intel chip would be impractical. The unlocked multiplier offers tuning headroom that the locked Intel chip does not provide. The AMD chip’s 92nd percentile ranking against all CPUs confirms it is a capable performer, but the Intel chip’s 91st percentile ranking, combined with its clean sweep in direct tests, indicates that the Intel part delivers more raw capability in return for higher power consumption and a desktop-only footprint.
