AMD Ryzen 7 7700X3D vs Intel Core Ultra 7 366H Comparison

# AMD Ryzen 7 7700X3D vs Intel Core Ultra 7 366H

The database contains benchmark results for the Intel Core Ultra 7 366H, a mobile processor, while the AMD Ryzen 7 7700X3D has no recorded benchmark scores in the current dataset. This asymmetry defines the comparison: the Intel part has measurable performance data across multiple workloads, while the AMD part's evaluation must rely on its architectural and specification profile. The Intel Core Ultra 7 366H sits at the 87th percentile among all CPUs in the database, with an average benchmark score of 41,263. Its nearest rivals include the Intel Core Ultra 7 356H with an average score of 41,215, the AMD Ryzen AI 5 PRO 440 at 41,208, the AMD Ryzen 9 5900X at 41,376, and the Intel Core Ultra X7 358H at 40,967. The recorded data shows a tight cluster of performance around this tier, with the 366H trailing the Ryzen 9 5900X by 0.3 percent while leading the other three rivals by margins of 0.1 to 0.7 percent.

Where Each One Wins

The Intel Core Ultra 7 366H wins in every measurable benchmark category because it is the only processor in this comparison with recorded scores. Its wins span Cinebench R15, R20, and R23 in both multicore and singlecore tests, plus PassMark workloads covering multithread, single-thread, physics, integer math, floating point math, data compression, data encryption, extended instructions, prime number finding, and random string sorting. The AMD Ryzen 7 7700X3D, by contrast, has zero recorded benchmarks in the database, meaning its wins cannot be established from measured data.

A use-case split emerges from the Intel scores alone. The Cinebench R23 multicore score of 28,477 and the PassMark multithread score of 33,429 indicate strong sustained throughput for rendering and parallel workloads. The Cinebench R23 singlecore score of 4,020 and the PassMark single-thread score of 4,043 point to capable single-thread performance for lightly threaded applications. The PassMark physics score of 2,880 suggests moderate performance in physics simulation, while the floating point math score of 103,615 and integer math score of 83,695 show different strengths across arithmetic workloads. The data compression score of 327,455 is notably high compared to the encryption score of 25,845, which indicates a large gap between compression throughput and encryption throughput. The extended instructions score of 26,901 and the random string sorting score of 39,814 round out the picture, with prime number finding at 326 being the lowest recorded score in the set.

The AMD processor's potential wins must be inferred from specifications rather than measurements. Its 96 MB shared L3 cache, 8 cores, 16 threads, and 5 nm process node suggest strengths in cache-sensitive workloads, but the database provides no scores to confirm this. The comparison is therefore one-sided in terms of measured data.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two processors. The wins for the Intel Core Ultra 7 366H are its own absolute scores, since the AMD Ryzen 7 7700X3D has no measured results to compare against. The most informative approach is to examine the Intel part's scores in detail.

In Cinebench R23, the 366H scores 28,477 in multicore and 4,020 in singlecore. The ratio between these scores indicates strong scaling across its 16 cores. In Cinebench R20, the multicore score is 11,960 and the singlecore score is 1,688, while in Cinebench R15 the multicore score is 2,870 and the singlecore score is 405. These three Cinebench versions show consistent progression across generations of the test.

The PassMark results reveal workload-specific behavior. The multithread score of 33,429 and the single-thread score of 4,043 show a roughly 8.3 to 1 ratio, which is lower than the 16-core count might suggest, indicating imperfect scaling. The floating point math score of 103,615 exceeds the integer math score of 83,695 by roughly 23.8 percent, showing a floating point advantage. The data compression score of 327,455 is more than 12 times the data encryption score of 25,845, a substantial gap that suggests the encryption workload is not a strength. The extended instructions score of 26,901 and the random string sorting score of 39,814 fill out the remaining data points. The physics score of 2,880 and the prime number finding score of 326 are the two lowest results in the set.

Since the AMD Ryzen 7 7700X3D has no scores, the head-to-head section cannot identify any wins for that processor. The Intel part wins all measured comparisons by default of having data.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 7 7700X3D has 8 cores and 16 threads, while the Intel Core Ultra 7 366H has 16 cores and 16 threads.

The manufacturing differs, with TSMC producing the AMD chip and Intel producing its own chip. The Intel processor uses a newer 3 nm process compared to the AMD processor's 5 nm process.

The Verdict

The data supports only one measured verdict: the Intel Core Ultra 7 366H is the only processor in this comparison with recorded performance. Its 87th percentile ranking and average benchmark score of 41,263 place it in a competitive tier, with its nearest rivals all scoring within a narrow band from 40,967 to 41,376. The 366H's performance relative to those rivals is nearly flat, with margins of 0.1 to 0.7 percent ahead of three rivals and 0.3 percent behind the AMD Ryzen 9 5900X.

The AMD Ryzen 7 7700X3D cannot be evaluated on performance grounds because the database contains no benchmark results for it. Its specifications suggest a different design philosophy, with 8 cores versus 16, a 120 watt TDP versus 25 watts, and a 96 MB L3 cache versus 18 MB. The AMD part targets desktops with a socketed AM5 platform, while the Intel part targets mobile devices with a BGA 2540 socket. The Intel part has a higher boost clock, higher memory bandwidth, and a newer process node, while the AMD part has a larger L3 cache, ECC memory support, more PCIe lanes, and a recorded launch MSRP of $329.

For users who rely on measured benchmark data, the Intel Core Ultra 7 366H is the only option with verified scores. Its 28,477 Cinebench R23 multicore score and 4,020 singlecore score, along with its PassMark results across 14 workloads, provide a complete performance picture. The AMD Ryzen 7 7700X3D remains an unknown quantity in the database, with its potential performance left to specification-based inference. The verdict from the recorded data is clear: the Intel processor delivers measurable performance in the 87th percentile, while the AMD processor awaits benchmark coverage.
