AMD Ryzen 7 PRO 8840U vs Intel Core 7 253PE Comparison

Head-to-Head Benchmarks

The benchmark data records a decisive overall victory for the Intel Core 7 253PE, which wins 16 of the 17 recorded comparisons. The AMD Ryzen 7 PRO 8840U claims only a single win, and that win is narrow. In passmark_random_string_sorting, the AMD scores 33109 against Intel's 32777, a 1% advantage. That is the only benchmark where AMD comes out ahead.

The Intel part wins every Cinebench test by a consistent margin. In cinebench_r15_multicore, Intel scores 2507 against AMD's 2041, a delta of -18.6% from AMD's perspective. The same -18.6% delta repeats across cinebench_r15_singlecore, cinebench_r20_multicore, cinebench_r20_singlecore, cinebench_r23_multicore, and cinebench_r23_singlecore. The single-core gap in Cinebench R23 is substantial: Intel scores 3512, AMD scores 2859. That is a lead of roughly 22.8% for Intel in single-threaded rendering work. The R23 multicore result shows Intel at 24880 versus AMD at 20254, an 18.6% deficit for AMD.

PassMark results tell a similar story with larger deltas in some tests. The largest gap appears in passmark_find_prime_numbers, where Intel scores 138 and AMD scores 76, a 44.9% deficit for AMD. Prime number finding is a workload that rewards high core counts and high clocks, and Intel delivers both here. passmark_floating_point_math shows Intel at 80870 versus AMD at 50746, a 37.2% gap. That is a major difference in floating-point throughput. passmark_physics also favors Intel heavily: 1845 versus 1174, a 36.4% deficit for AMD.

Integer math favors Intel as well, with 114158 versus 88339, a 22.6% gap. Data compression shows Intel at 339133 versus AMD at 272664, a 19.6% deficit for AMD. Data encryption is closer, with Intel at 18385 versus AMD at 16441, a 10.6% gap. Extended instructions score 21806 for Intel against 19132 for AMD, a 12.3% gap. passmark_multithread records Intel at 29271 and AMD at 23850, an 18.5% gap. passmark_singlethread shows Intel at 3955 versus AMD at 3641, a 7.9% gap, the smallest Cinebench-style single-thread difference outside the random string sorting test.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 7 PRO 8840U uses 8 cores and 16 threads on the Zen 4 architecture, codenamed Hawk Point. It belongs to the 8000 series and is built on a 4 nm process at TSMC. The die contains 25,000 million transistors on a 178 mm² die. The Intel Core 7 253PE uses 10 cores and 20 threads, codenamed Bartlett Lake, built on a 10 nm process at Intel. The database records no transistor count or die size for the Intel part.

Cache layouts differ significantly. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Intel chip has more than double the L3 capacity, which helps in workloads that repeatedly access large data sets. The per-core L2 is also doubled on Intel.

Memory support shows a split. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use a dual-channel memory bus, and the recorded memory bandwidth is identical at 89.6 GB/s. Both support ECC memory. PCIe capability differs: AMD uses Gen 4 with 20 lanes (CPU only), while Intel uses Gen 5 with 16 lanes (CPU only). The integrated graphics also differ: AMD includes the Radeon 780M, Intel includes the UHD Graphics 730.

Clock speeds and power envelopes are not close. AMD's base clock is 3.30 GHz with a boost of 5.10 GHz and a TDP of 28 watts. Intel's base clock is 2.50 GHz with a boost of 5.50 GHz and a TDP of 65 watts. The Intel part draws more than double the power budget, which explains its higher boost ceiling and sustained multicore output. Socket compatibility differs as well: AMD uses AMD Socket FP7, Intel uses Intel Socket 1700. The market segments also differ, with AMD listed as Mobile and Intel as Desktop. Release dates are far apart, with AMD releasing on 2024-04-15 and Intel on 2026-03-08.

Where Each One Wins

The Intel Core 7 253PE wins across nearly every measured workload. Rendering, physics simulation, floating-point math, integer math, encryption, compression, and extended instruction workloads all favor Intel. The largest margins come from prime number finding, floating-point math, and physics, all of which benefit from the combination of 10 cores, 20 threads, 33 MB of L3 cache, and a 5.50 GHz boost clock. The 65-watt TDP gives Intel the headroom to sustain high multicore throughput. For users running heavy compute tasks such as video rendering, scientific simulation, or code compilation, the data points clearly to Intel.

The AMD Ryzen 7 PRO 8840U wins only random string sorting, and that win is just 1%. This is a narrow edge in a specific sorting workload. The AMD part also has the advantage of a 28-watt TDP, which is less than half of Intel's 65-watt envelope. That makes it the more power-efficient choice for mobile or thermally constrained systems. The Radeon 780M integrated graphics are a significant feature for systems that rely on the iGPU, though the database records no benchmark scores for graphics performance. The AMD part's smaller process node, 4 nm versus Intel's 10 nm, and its lower power draw make it the practical pick for thin-and-light laptops, where sustained high power draw is not possible.

For single-threaded responsiveness, Intel wins with a 7.9% gap in passmark_singlethread and roughly 22.8% in Cinebench R23 single-core. Applications that depend on one fast core, such as older games or lightly threaded productivity tools, will respond better on Intel. The Intel part's higher boost clock of 5.50 GHz versus AMD's 5.10 GHz helps in these scenarios.

The Verdict

The recorded data favors the Intel Core 7 253PE in almost every measurable way. It wins 16 of 17 head-to-head benchmarks, with margins ranging from 7.9% to 44.9%. Its multicore scores in Cinebench and PassMark are consistently higher, and its single-thread scores are also ahead. Users who need maximum compute throughput across rendering, physics, math, and data workloads should choose the Intel part.

The AMD Ryzen 7 PRO 8840U is the better fit for power-constrained environments. Its 28-watt TDP, versus Intel's 65-watt TDP, makes it the only sensible option for thin mobile systems where sustained high power draw is impossible. The AMD part also carries a 4 nm process node, the Radeon 780M integrated graphics, and a 1% win in random string sorting. But in raw performance, the data shows no contest: Intel leads in every major category except that single sorting test. For desktop users with adequate cooling and power delivery, the Intel Core 7 253PE is the stronger processor by a wide margin.
