AMD Ryzen 5 3600X vs Intel Core i7-1270P Comparison

The Intel Core i7-1270P and AMD Ryzen 5 3600X represent two very different approaches to computing: a mobile-first hybrid design versus a desktop-focused high-power chip. Benchmark results show a clear split between raw multi-threaded workloads and specific math-heavy tasks, with each processor claiming distinct victories. The data indicates the AMD part wins the majority of head-to-head tests, but the Intel part exhibits notable strengths in specific instruction-heavy scenarios.

Head-to-Head Benchmarks

The AMD Ryzen 5 3600X dominates the Cinebench suite, winning every single test by a consistent margin. In Cinebench R23 multi-core, the AMD scores 15,430 against the Intel’s 13,938, a 9.7% advantage. The single-core results follow the same pattern: the AMD part scores 2,178 versus 1,967 in R23 single-core, also a 9.7% delta. This consistency extends to Cinebench R20 and R15, where the AMD chip leads by 9.7% and 9.6% respectively in both multi-core and single-core variants. The AMD processor similarly wins PassMark’s multi-thread test with 18,154 points compared to 16,957, a 6.6% edge.

The AMD chip’s lead grows substantially in several PassMark sub-tests. In data compression, the Ryzen scores 224,318 versus 184,917, a 17.6% advantage. Data encryption shows a 20.9% gap (14,255 vs. 11,276). The largest margin comes in the extended instructions test, where the AMD wins by 28.4% (14,773 vs. 10,575). The find prime numbers test is the most lopsided of all: AMD scores 110 against Intel’s 66, a 40% difference. Random string sorting also favors AMD by 15.6% (24,343 vs. 20,546).

However, the Intel Core i7-1270P claims decisive wins in three key areas. The most striking is floating-point math, where Intel scores 43,168 against AMD’s 29,339 — a massive 47.1% advantage. Integer math also goes to Intel with a 26.2% lead (63,016 vs. 49,934). The single-thread PassMark test shows Intel at 3,354 versus AMD’s 2,649, a 26.6% victory. Notably, these Intel wins are larger in percentage terms than most of AMD’s victories, indicating that while AMD wins more tests, Intel’s wins are often by wider margins.

Architecture Differences

The two processors are built on fundamentally different architectures. Intel uses Alder Lake-P, a hybrid design combining performance and efficiency cores on a 10 nm process, fabricated by Intel itself. The chip has 12 cores and 16 threads, with a base clock of 2.20 GHz and a boost clock of 4.80 GHz. It features 18 MB of shared L3 cache, with 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The die size is 217 mm², and it supports both DDR4 and DDR5 memory in a dual-channel configuration. The Intel part includes integrated Iris Xe graphics with 96 execution units, uses PCIe Gen 4 with 20 CPU lanes, and has a 28W TDP. It is mobile-oriented, fitting the Intel BGA 1744 socket.

AMD’s Ryzen 5 3600X uses the Zen 2 architecture, codenamed Matisse, built on a 7 nm process at TSMC. This is a desktop chip with 6 cores and 12 threads, running at a 3.80 GHz base and 4.40 GHz boost. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a larger 32 MB of shared L3 cache. The die is much smaller at 74 mm², and the processor contains 3,800 million transistors. It supports only DDR4 memory in dual-channel mode, with a memory bandwidth of 51.2 GB/s. The AMD chip has no integrated graphics, uses PCIe Gen 4, and has a 95W TDP. It fits the AMD Socket AM4 and has an unlocked multiplier for overclocking.

These differences explain much of the benchmark behavior. The AMD’s larger L3 cache (32 MB vs. 18 MB) likely contributes to its wins in data compression, encryption, and extended instructions — workloads that benefit from larger on-die caching. The Intel’s higher boost clock (4.80 GHz vs. 4.40 GHz) and its hybrid core layout help in single-thread tests and math-heavy tasks. The process node difference (7 nm vs. 10 nm) gives AMD a transistor density advantage, but Intel’s design compensates with more cores and threads.

Where Each One Wins

The AMD Ryzen 5 3600X is the clear winner for multi-threaded productivity workloads. Its Cinebench scores are consistently 9.7% higher across all versions, indicating strong rendering performance. The data compression and encryption wins (17.6% and 20.9%) suggest it handles file archiving, database workloads, and encrypted communications more efficiently. The 40% margin in find prime numbers points to superior integer-heavy algorithm execution. The physics test also favors AMD (1,186 vs. 1,120, a 5.6% edge), implying better performance in simulation workloads. For users running video encoding, 3D rendering, or data processing that uses multiple cores, the AMD part is the better choice.

The Intel Core i7-1270P wins decisively in floating-point math with a 47.1% advantage. This makes it suitable for scientific computing, financial modeling, and any workload that relies heavily on floating-point operations. Its 26.2% lead in integer math further strengthens its case for general-purpose number crunching. The 26.6% single-thread PassMark victory indicates superior per-core performance, which benefits lightly-threaded applications like web browsing, office productivity, and some legacy software. The Intel chip’s integrated graphics also gives it an advantage for basic display output without a dedicated GPU, though this is not reflected in the benchmark scores.
