AMD Ryzen 7 4800H vs Intel Core i7-1270P Comparison

Head-to-Head Benchmarks

The head-to-head results show a near split: the Intel Core i7-1270P wins 8 tests, while the AMD Ryzen 7 4800H wins 7. The most dramatic single-core margin belongs to Intel. In Cinebench R23 single-core, the i7-1270P scores 1967 against 1253.5 for the Ryzen, a 56.9% lead. The same pattern holds in Cinebench R15 single-core, where Intel wins 198 to 188, a 5.3% edge, and in PassMark single-thread, where Intel posts 3354 versus 2597, a 29.1% advantage. The i7-1270P also dominates the Cinebench R23 multi-core test, scoring 13938 against 11135.5, a 25.2% win. That result flips the older Cinebench R15 multi-core test, where the Ryzen 7 4800H takes a decisive 1854 to 1404 victory, a 24.3% margin.

Data encryption follows a similar path: 15530 for AMD against 11276, a 27.4% lead. Extended instructions also favor AMD, with 17035 versus 10575, a 37.9% swing. Random string sorting goes to AMD at 29181 versus 20546, a 29.6% difference. Integer math is nearly even, with AMD just ahead at 63999 versus 63016, a slim 1.5% margin. PassMark multithread also favors AMD, 18222 to 16957, a 6.9% edge.

Intel takes the remaining wins with clear margins. PassMark find prime numbers shows Intel at 66 versus 33, a perfect 100% delta. Floating point math goes to Intel, 43168 to 37312, a 15.7% win. Physics simulation is also Intel's, 1120 to 754, a 48.5% gap. The overall averages reflect this balance: the i7-1270P holds an average benchmark score of 22502, while the Ryzen 7 4800H sits at 21749. In the database percentile ranking, Intel lands at the 76th percentile, AMD at the 75th. The nearest rivals for Intel include the Core i5-13500H at 22468 (0.2% behind) and the Core Ultra 5 135U at 22618 (0.5% ahead). For AMD, the closest competitor is the Ryzen 5 5600X at 21771 (0.1% behind), with the Xeon D-1746TER at 21635 (0.5% behind).

Architecture Differences

The two processors come from different design philosophies. Intel's i7-1270P uses Alder Lake architecture on a 10 nm process, built by Intel itself. It packs 12 cores and 16 threads, with a hybrid layout typical of Alder Lake-P. The base clock is 2.20 GHz, boosting to 4.80 GHz. The die size measures 217 mm². Cache is generous: 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3. Memory support covers DDR4 and DDR5, through a dual-channel bus. PCIe is Gen 4 with 20 lanes from the CPU. The integrated graphics are Iris Xe with 96 execution units.

AMD's Ryzen 7 4800H is a Zen 2 part on a 7 nm TSMC process, codenamed Renoir. It has 8 cores and 16 threads, with a base clock of 2.90 GHz and a boost of 4.20 GHz. The transistor count is 9,800 million on a 156 mm² die. Cache is smaller: 64 KB L1 per core, 512 KB L2 per core, and 8 MB shared L3. Memory support is DDR4 and LPDDR4, dual-channel, with a recorded memory bandwidth of 51.2 GB/s. PCIe is Gen 3 only. The integrated graphics are Radeon with 448 shader processors.

The node difference matters. Intel's 10 nm process is older than AMD's 7 nm, yet the i7-1270P still achieves a higher boost clock (4.80 GHz versus 4.20 GHz) and wins single-core benchmarks by wide margins. The cache structure also diverges sharply: Intel provides more than double the L3 (18 MB versus 8 MB) and larger per-core L2 (1.25 MB versus 512 KB), which likely contributes to the floating point and physics wins. AMD counters with a larger L1 per core (64 KB versus 80 KB is actually smaller, but the per-core L1 is not the deciding factor here), and the Ryzen's higher base clock (2.90 GHz versus 2.20 GHz) helps in sustained multi-threaded loads. The TDP tells a story too: Intel runs at 28 W, AMD at 45 W. That higher power envelope for AMD explains some of its multi-core wins, but it also means the i7-1270P achieves comparable multithread scores at a much lower power target.

Where Each One Wins

The Intel i7-1270P is the choice for single-threaded and lightly threaded tasks. Its 56.9% lead in Cinebench R23 single-core and 29.1% lead in PassMark single-thread make it clearly faster for everyday responsiveness, web browsing, and applications that rely on one or two cores. The 48.5% win in physics simulation suggests it handles game physics or similar real-time calculations better. Floating point math, with a 15.7% edge, points to scientific or engineering workloads that use vectorized operations. The find prime numbers result, doubling AMD's score, indicates strong integer sequence processing, though this is a niche workload.

The AMD Ryzen 7 4800H is the better fit for data-centric and compression-heavy tasks. Its 31.3% lead in data compression and 29.6% lead in random string sorting make it ideal for file archiving, database operations, or any workload that shuffles large blocks of data. Data encryption at 27.4% ahead suggests faster VPN or disk encryption performance. Extended instructions at 37.9% ahead means AMD handles advanced instruction sets more efficiently, which can benefit media encoding or cryptography. The multithread score, 6.9% ahead, and the Cinebench R15 multi-core win at 24.3%, indicate that older, well-parallelized rendering workloads still favor AMD.

The split is not clean-cut. Intel wins the newer Cinebench R23 multi-core test by 25.2%, while AMD wins the older R15 multi-core by 24.3%. That suggests Intel's advantage emerges in newer, more complex multi-threaded workloads, while AMD holds an edge in simpler, older parallel tasks. PassMark integer math is essentially a tie, so neither chip dominates pure integer throughput. For a user deciding based on the recorded data: pick Intel for responsive single-core performance and modern rendering, pick AMD for data manipulation and legacy multithreading.

The Verdict

The data points to a clear split based on workload type. For users who prioritize single-thread responsiveness, modern rendering, and floating-point operations, the Intel Core i7-1270P is the stronger pick. Its 56.9% lead in Cinebench R23 single-core and 25.2% lead in Cinebench R23 multi-core show it handles newer software better. The 48.5% win in physics and 15.7% win in floating point math reinforce this. The 28 W TDP also means it delivers this performance in a more power-efficient package.

For users who work with large datasets, compression, or encryption, the AMD Ryzen 7 4800H is the better choice. Its 31.3% lead in data compression, 29.6% lead in random string sorting, and 27.4% lead in encryption make it a data-handling specialist. The 37.9% win in extended instructions and 6.9% win in multithread add to its appeal for batch processing. The higher 45 W TDP is a trade-off, but it enables sustained throughput in these workloads.

The overall benchmark averages are close: 22502 for Intel versus 21749 for AMD, a difference of about 3.4%. Both sit near the 75th percentile in the database, with Intel at 76 and AMD at 75. The Ryzen 5 5600X, a desktop chip, is AMD's nearest rival at 21771, while Intel's i5-13500H at 22468 is almost identical to the i7-1270P. The verdict is not about which is universally faster, but which fits the intended use. Intel for interactive and modern tasks, AMD for data-intensive and legacy parallel workloads.
