Architecture Differences

The architectural gap between these two parts is substantial. The Intel Core 7 253PE is a desktop-class processor built on Intel’s 10 nm process node and hails from the Bartlett Lake codename, representing the Core 7 generation. It uses the Intel Socket 1700 platform and integrates UHD Graphics 730. In contrast, the AMD Ryzen 9 7940H is a mobile processor from the 7000 series, built on TSMC’s 4 nm process with the Zen 4 architecture under the Phoenix codename. It uses the AMD Socket FP8 and integrates Radeon 780M graphics.

Core and thread counts differ significantly. The Intel part fields 10 cores and 20 threads, while the AMD part has 8 cores and 16 threads. This gives the Intel chip a 25% core advantage and a 25% thread advantage. The cache hierarchy also diverges: Intel provides 80 KB of L1 cache per core and 2 MB of L2 per core, with 33 MB of shared L3. AMD provides 64 KB of L1 per core and 1 MB of L2 per core, with only 16 MB of shared L3. The Intel chip’s larger L3 cache is more than double that of the AMD.

The process technology gap is notable. AMD’s 4 nm node from TSMC is significantly more advanced than Intel’s 10 nm process, contributing to the AMD’s lower 35 W TDP compared to Intel’s 65 W TDP. The AMD processor also has a smaller die size at 178 mm² and contains 25,000 million transistors. Memory support differs as well: the Intel chip supports both DDR4 and DDR5, while the AMD chip supports only DDR5. Both use dual-channel memory buses with identical peak bandwidth of 89.6 GB/s. PCIe connectivity also differs, with Intel offering Gen 5 with 16 lanes (CPU only) and AMD offering Gen 4 with 20 lanes (CPU only).

Clock speeds tell another story. Intel lists a 2.50 GHz base clock and a 5.50 GHz boost clock. AMD lists a higher 4.00 GHz base clock but a lower 5.20 GHz boost clock. Neither processor has an unlocked multiplier. The Intel chip has a launch MSRP of $384, while the AMD chip has no listed launch MSRP. The Intel part is marked for the Desktop market segment, while the AMD part is for Mobile.

The Verdict

The data paints a clear picture of two processors with different strengths. The Intel Core 7 253PE is the better choice for workloads that rely on raw integer and floating-point throughput, multi-core rendering, and prime number calculations. It wins 13 of the 17 head-to-head benchmarks, including all six Cinebench tests, though its margins in those rendering tests are slim, ranging from 0.7% to 0.9%. The Intel chip’s 70.4% lead in find prime numbers and 41.9% lead in physics tests are its most dominant results.

The AMD Ryzen 9 7940H is the better option for data compression, encryption, extended instruction sets, and random string sorting. It wins four benchmarks, with its largest victories being 18.6% in extended instructions and 12.9% in data encryption. The AMD chip also leads in data compression by 3.7% and random string sorting by 22.1%. For users prioritizing these specific workloads, the AMD part offers substantial advantages.

The overall average benchmark scores are nearly identical, with the Intel part ahead by just 0.3%. Both processors sit at the 87th percentile among all CPUs. The Intel chip’s higher core count and larger cache likely drive its wins in multi-threaded and math-heavy tasks, while the AMD chip’s newer 4 nm process and Zen 4 architecture shine in data-oriented and cryptographic workloads. The Intel part’s desktop socket and higher TDP suggest it is intended for stationary systems, while the AMD part’s mobile socket and lower TDP indicate a focus on laptops.

Head-to-Head Benchmarks

The Intel Core 7 253PE establishes a consistent, if narrow, lead across all Cinebench tests. In multi-core R15, it scores 2507 against AMD’s 2490, a 0.7% margin. The single-core R15 result is similar, 354 versus 351, a 0.9% edge. R20 multi-core shows 10449 versus 10375, again 0.7%. R20 single-core is 1475 versus 1464, an 0.8% lead. R23 multi-core is 24880 versus 24703, and R23 single-core is 3512 versus 3487, both at 0.7%. The PassMark multithread test also goes to Intel, 29271 versus 29063, a 0.7% margin. These results indicate a small but repeatable advantage for Intel in rendering and general multi-threaded tasks.

Intel’s largest wins come in specific PassMark subtests. The find prime numbers test is a blowout: Intel scores 138 versus AMD’s 81, a 70.4% advantage. Physics is another decisive win, with Intel at 1845 versus AMD’s 1300, a 41.9% lead. Floating point math also favors Intel heavily, 80870 versus 62057, a 30.3% margin. Integer math is less extreme but still substantial, 114158 versus 101977, an 11.9% win. The single-thread test is essentially a tie, with Intel at 3955 and AMD at 3952, a 0.1% difference. These results suggest the Intel architecture excels at arithmetic and physics calculations.

The AMD Ryzen 9 7940H counters with four wins, all in data-centric PassMark tests. The most significant is extended instructions, where AMD scores 26804 versus Intel’s 21806, an 18.6% advantage. Data encryption favors AMD by 12.9%, with scores of 21096 versus 18385. Random string sorting is a 22.1% win for AMD, 42093 versus 32777. Data compression is closer, with AMD ahead 352077 versus 339133, a 3.7% margin. These results indicate that AMD’s Zen 4 architecture handles cryptographic and string manipulation workloads more efficiently, likely due to its newer process node and instruction set optimizations. The overall win count stands at 13 for Intel and 4 for AMD, yet the average benchmark scores remain within 0.3% of each other, underscoring how workload-dependent the choice is.
