AMD Ryzen 7 7700 vs Intel Core Ultra 7 366H Comparison

Head-to-Head Benchmarks

The benchmark data splits the field nearly evenly, with the AMD Ryzen 7 7700 taking 8 wins and the Intel Core Ultra 7 366H taking 7. The most decisive results, however, belong to AMD. The Ryzen 7 7700 dominates in passmark_extended_instructions with a score of 96,902 against 26,901 for Intel, a 260.2% advantage. Random string sorting also heavily favors AMD: 101,836 versus 39,814, a 155.8% lead. Data compression shows AMD ahead by 23.7% (405,084 vs 327,455), and integer math favors AMD by 31.8% (110,295 vs 83,695).

Intel’s wins are concentrated in modern rendering workloads and floating-point math. The most striking result is Cinebench R23 multicore, where Intel scores 28,477 against AMD’s 18,760, a 34.1% lead. The single-core R23 gap is even larger in percentage terms: Intel scores 4,020 versus 1,930 for AMD, a 52% difference. In Cinebench R15 single-core, Intel wins by 24% (405 vs 308), while in floating-point math Intel leads by 36.1% (103,615 vs 66,246). Intel also wins in physics (2,880 vs 1,978, a 31.3% lead), prime number finding (326 vs 197, a 39.6% lead), and data encryption (25,845 vs 23,858, a 7.7% lead).

The closest contest is in single-thread PassMark, where AMD edges Intel by 0.5% (4,063 vs 4,043). The overall multithread PassMark score also goes to AMD, but narrowly: 34,470 versus 33,429, a 3.1% margin. The Cinebench R15 multicore result is close as well, with AMD ahead 6.2% (3,047 vs 2,870).

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 7 7700 is a desktop part built on TSMC’s 5 nm process, featuring 8 cores and 16 threads. The Intel Core Ultra 7 366H is a mobile processor on Intel’s 3 nm node, with 16 cores and 16 threads. Despite having twice the core count, Intel matches the thread count, indicating a hybrid architecture with some cores lacking hyper-threading.

Cache hierarchies differ substantially. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. Intel counters with 192 KB of L1 per core, 2.5 MB of L2 per core, but only 18 MB of shared L3. The larger L3 pool helps AMD in data-heavy workloads, which is reflected in its compression and sorting victories.

Clock speeds tell a similar story of divergent priorities. AMD operates at a base of 3.80 GHz with a boost of 5.30 GHz, while Intel starts at 2.00 GHz and boosts to 4.80 GHz. The higher sustained clocks benefit AMD’s integer throughput, while Intel’s lower base clock likely enables its 25 W TDP versus AMD’s 65 W TDP.

Memory support also differs. Both support dual-channel DDR5, but Intel adds LPDDR5X support and achieves a higher memory bandwidth of 115.2 GB/s versus 83.2 GB/s for AMD. This bandwidth advantage appears in Intel’s floating-point and encryption results. AMD supports ECC memory, which Intel does not.

PCIe connectivity is another split. AMD provides Gen 5 with 24 CPU lanes, while Intel provides Gen 5 with 12 CPU lanes. The integrated graphics are the Radeon Graphics on AMD versus Intel Xe3 Graphics on Intel. AMD’s multiplier is unlocked for overclocking; Intel’s is locked. AMD uses Socket AM5, while Intel uses BGA 2540, which is a soldered mobile socket.

Where Each One Wins

AMD Ryzen 7 7700 wins decisively in data manipulation and legacy integer workloads. The 260.2% lead in extended instructions suggests a substantial advantage for encryption, compression, and specialized instruction sets. Data compression at 405,084 versus 327,455 and integer math at 110,295 versus 83,695 make this the clear choice for archive handling, database operations, and general-purpose integer processing. The random string sorting win by 155.8% reinforces this picture for text processing and sorting algorithms.

The Ryzen 7 7700 also holds a slight but consistent edge in overall multithreaded PassMark performance (3.1% lead) and single-thread PassMark (0.5% lead). These results indicate a balanced desktop processor that can handle mixed workloads without a weak spot in core-to-core scaling.

Intel Core Ultra 7 366H wins in modern rendering and compute-heavy tasks. The 34.1% lead in Cinebench R23 multicore is the largest absolute score difference in the entire benchmark set, suggesting a major advantage in video rendering and 3D scene composition. The 52% lead in Cinebench R23 single-core is even more pronounced, indicating superior per-thread execution for the latest instruction sets. The physics score of 2,880 versus 1,978 shows a 31.3% lead, making Intel the better choice for simulation and physics-based computing.

Intel also leads in floating-point math with a 36.1% advantage, which is critical for scientific and engineering applications. The prime number finding score of 326 versus 197 (a 39.6% lead) and data encryption at 25,845 versus 23,858 round out Intel’s strengths in cryptography and algorithmic precision.

The Verdict

The data points to two distinct user profiles. The AMD Ryzen 7 7700 is the better choice for integer-heavy, data-centric desktop workloads. Its 31.8% integer math lead, 23.7% compression lead, and 155.8% random string sorting lead make it ideal for database management, file compression, and general software development. The unlock multiplier and ECC support also favor those who need overclocking and memory stability. The 87th percentile ranking against all CPUs, with an average benchmark score of 40,081, confirms it as a top-tier desktop chip.

The Intel Core Ultra 7 366H is the stronger pick for rendering, physics, and floating-point precision. The 34.1% Cinebench R23 multicore lead and 36.1% floating-point lead make it superior for video editing, 3D animation, and scientific simulations. The 25 W TDP also makes it suited for mobile systems with thermal constraints. Its average benchmark score of 41,263 places it in the same 87th percentile, but with a different strength profile: single-core dominance and higher memory bandwidth.

Choose the AMD Ryzen 7 7700 if your work revolves around integer-heavy, data-sorting, or compilation tasks. Choose the Intel Core Ultra 7 366H if your workload prioritizes rendering, physics, cryptography, or many-core Cinebench performance. The PassMark multithread score is nearly tied (AMD 3.1% ahead), so the decision hinges on the specific workload mix rather than overall speed.
