AMD Ryzen 7 8840U vs Intel Core i7-1360P Comparison

The AMD Ryzen 7 8840U is the dominant performer in this head-to-head, winning 12 of the 15 shared benchmarks against the Intel Core i7-1360P. The data is not close: AMD’s lead in multi-threaded workloads frequently exceeds 20%, and its advantage in specific instruction-heavy tasks reaches nearly 38%. The Intel part takes only three wins, and one of those is a tie. For any workload that scales across cores, the Ryzen 7 8840U is the clear choice, though the Intel chip does claim a notable single-core victory in one rendering test.

Head-to-Head Benchmarks

The most decisive result between these two mobile processors comes from PassMark’s extended instructions test. The AMD Ryzen 7 8840U scores 18,654, which is 37.9% ahead of the Intel Core i7-1360P’s 11,581. This is the largest margin in the entire comparison, indicating a substantial advantage in workloads that utilize advanced CPU instruction sets such as AVX-512 or similar. This is not a marginal win; it is a generational gap in execution efficiency.

Multi-threaded performance follows a similar pattern, though with slightly smaller margins. In Cinebench R23 multi-core, the AMD chip scores 12,972 against Intel’s 11,266.5, a 13.1% deficit for the i7-1360P. The older Cinebench R15 multi-core test shows an 8.2% win for AMD (2,024 vs. 1,858). PassMark’s multithread benchmark reinforces this trend, with AMD leading 23,346 to 18,632, a 20.2% advantage. The integer math test is even more lopsided: AMD scores 85,740 versus Intel’s 67,963, a 20.7% lead.

Data-centric workloads show the largest gaps outside of extended instructions. PassMark data compression favors AMD by 23.8% (267,525 vs. 203,746), and data encryption shows a 22.5% advantage for AMD (16,072 vs. 12,463). Random string sorting is another strong AMD result, with a 30% lead (32,158 vs. 22,522). These are not synthetic edge cases; they reflect real-world database, compression, and security workloads.

The Intel Core i7-1360P does manage to win one meaningful single-threaded test. In Cinebench R23 single-core, Intel scores 1,829 versus AMD’s 1,703, a 7.4% advantage. This is notable because it shows Intel’s Raptor Lake architecture still has a clock-for-clock single-thread edge in some rendering scenarios. However, the AMD chip wins the Cinebench R15 single-core test (266 vs. 258, a 3% margin) and the PassMark single-thread test (3,543 vs. 3,461, a 2.3% margin). So Intel’s single-core win is isolated to one benchmark generation.

The remaining Intel win is in PassMark physics, where Intel scores 1,280 against AMD’s 1,176, an 8.8% margin. The final shared benchmark, PassMark find prime numbers, is an exact tie at 78 for both processors. AMD wins the floating-point math test as well, scoring 48,820 versus Intel’s 45,997, a 5.8% lead. The overall score distribution is unambiguous: AMD wins the vast majority of tests, and its wins are often by double-digit percentages.

Where Each One Wins

The AMD Ryzen 7 8840U is the outright winner for multi-threaded productivity. If the workload involves rendering, video encoding, or 3D modeling that uses all cores, the data points to AMD. The 13.1% lead in Cinebench R23 multi-core and the 20.2% lead in PassMark multithread demonstrate that the 8-core Zen 4 design scales better than Intel’s 12-core hybrid layout. Similarly, for data-heavy tasks like compression, encryption, and string sorting, AMD’s 22.5% to 30% leads make it the only rational choice.

The Intel Core i7-1360P wins in two narrow niches. The first is in single-threaded rendering, specifically Cinebench R23 single-core, where its 7.4% lead suggests it can handle legacy or lightly-threaded rendering workloads slightly faster. The second is in physics calculations, as measured by PassMark, where Intel’s 8.8% advantage could translate to better performance in certain simulation or gaming physics engines. However, these wins are isolated and do not offset AMD’s broader dominance.

For users who prioritize floating-point math, AMD’s 5.8% lead in that specific test is relevant, but it is not as decisive as the integer math victory. The tie in finding prime numbers indicates that neither chip has a particular advantage in that specific algorithmic task. Overall, the use-case split is stark: AMD for everything that uses multiple cores or heavy data processing, Intel only for a narrow set of single-threaded or physics-centric tasks.

Architecture Differences

The two processors are built on fundamentally different architectures and manufacturing processes. The Intel Core i7-1360P uses Raptor Lake architecture on Intel’s 10 nm process, fabricated in-house. It features 12 cores and 16 threads, with a base clock of 2.20 GHz and a boost clock of 5.00 GHz. The AMD Ryzen 7 8840U uses Zen 4 architecture on a 4 nm process from TSMC, with 8 cores and 16 threads, a base clock of 3.30 GHz, and a boost clock of 5.10 GHz. AMD’s process node advantage is significant, allowing for higher transistor density.

The transistor counts highlight this difference. AMD’s chip packs 25,000 million transistors on a 178 mm² die, while Intel’s transistor count and die size are not listed in the data. The cache configurations also differ. Intel provides 80 KB of L1 cache per core, 2 MB of L2 per core, and 18 MB of shared L3 cache. AMD offers 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. Despite having fewer cores, AMD’s higher clock speeds and smaller process node help it achieve superior multi-threaded scores.

Memory support is another differentiator. Intel supports both DDR4 and DDR5 memory, while AMD supports only DDR5. Both are dual-channel, but AMD’s memory bandwidth is listed as 89.6 GB/s, while Intel’s is not specified. Both chips use PCIe Gen 4 with 20 lanes (CPU only) and have integrated graphics: Intel’s Iris Xe Graphics 96EU versus AMD’s Radeon 780M. Neither supports ECC memory. The sockets are incompatible: Intel uses BGA 1744, while AMD uses Socket FP8.

The release dates differ by nearly a year, with Intel launching on January 3, 2023, and AMD on December 5, 2023. Both are active production parts, and neither has an unlocked multiplier. AMD’s part number list includes three variants (FP7r2, FP7, FP8), while Intel has a single part number (SRMJ8). Intel’s launch MSRP is $480; AMD’s launch MSRP is not listed.

The Verdict

The data is clear: the AMD Ryzen 7 8840U is the superior processor for almost all workloads. With 12 wins out of 15 head-to-head benchmarks, and decisive margins in multi-threaded (13.1% to 20.2%), data compression (23.8%), encryption (22.5%), and extended instructions (37.9%), AMD offers a significantly faster mobile platform. The only reasons to choose the Intel Core i7-1360P are if the workload is specifically single-threaded Cinebench R23 rendering (where Intel leads by 7.4%) or PassMark physics (8.8% lead). These are narrow niches.

Both chips have identical percentile rankings (76th) against all CPUs, and their average benchmark scores are close (Intel at 24,344, AMD at 23,982), but the head-to-head data shows AMD winning where it matters. The Intel chip’s closest rivals include the AMD Ryzen 5 PRO 6650H and Intel Core i5-13400, while AMD’s rivals include the Ryzen 5 8600G and Xeon 6333P. This suggests that the Intel chip is competing with AMD’s lower-tier Ryzen 5 parts, while the Ryzen 7 8840U is positioned against Intel’s desktop-class Xeon parts.

For a mobile user who needs maximum multi-core throughput for rendering, data processing, or encryption, the Ryzen 7 8840U is the only defensible choice. The 20%+ margins in integer math and multithread performance are not trivial. For users who have a specific, proven need for Intel’s single-thread Cinebench advantage, the i7-1360P is acceptable, but it is a compromise. The tie in prime number finding is irrelevant to real-world decisions.
