AMD Ryzen 7 7700X3D vs Intel Core Ultra 5 336H Comparison

Where Each One Wins

The benchmark data splits these two processors along clear lines: the AMD Ryzen 7 7700X3D is a desktop part aimed at high-throughput workloads, while the Intel Core Ultra 5 336H is a mobile processor that trades raw core count for efficiency and single-thread speed. In the recorded measurements, the Intel chip wins nearly every benchmark where scores exist, while the AMD chip has no recorded benchmark scores in the database, leaving its strengths to be inferred from its architecture rather than measured results.

The Intel Core Ultra 5 336H dominates the entire Passmark suite. Its passmark_multithread score of 28,545 and passmark_single_thread score of 4,013 show a processor that handles both parallel and single-threaded tasks with authority. The Cinebench results reinforce this: a Cinebench R23 multicore score of 23,991 and a single-core score of 3,387 place it well above typical mobile processors. The data shows the Intel part wins on every measured metric, from floating-point math (82,415) to integer math (62,070) to data compression (280,340).

The AMD Ryzen 7 7700X3D, with its 96 MB shared L3 cache and 8 cores, targets a different use case entirely. Its architecture suggests applications that repeatedly access large datasets benefit from the massive cache, even though no benchmark scores exist to quantify this. The desktop socket, 120 W TDP, and dual-channel DDR5 memory support point to a stationary workstation or gaming rig, not a portable system. The database records no wins for the AMD part in head-to-head benchmarks, but the specification differences indicate its advantage would appear in cache-sensitive workloads, not in the general-purpose tests where the Intel chip currently holds all recorded scores.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 7700X3D uses the Zen 4 Raphael architecture on a 5 nm TSMC process, with 8 cores and 16 threads. Its 11,270 million transistors fit on a 71 mm² die. The Intel Core Ultra 5 336H uses the Panther Lake architecture on Intel's own 3 nm process, with 16 cores and 16 threads (the equal core and thread counts indicate hybrid core types where efficiency cores lack hyperthreading). The Intel die size and transistor count are not recorded.

Cache configurations differ sharply. The AMD part allocates 64 KB L1 per core, 1 MB L2 per core, and 96 MB shared L3. That 96 MB L3 is the defining feature, likely a 3D-stacked cache design given the X3D suffix. The Intel part uses 192 KB L1 per core, 2.5 MB L2 per core, and only 18 MB shared L3. The Intel L1 and L2 are larger per core, but the L3 capacity is less than a fifth of the AMD's.

Memory support also diverges. The AMD processor uses dual-channel DDR5 with 83.2 GB/s bandwidth and supports ECC memory. The Intel processor supports both DDR5 and LPDDR5X, achieving 115.2 GB/s bandwidth, but lacks ECC. The AMD chip has Radeon Graphics integrated, while the Intel chip has Xe3 Graphics. PCIe connectivity favors AMD: 24 Gen 5 lanes versus 12 Gen 5 lanes for Intel. The Intel chip uses a BGA 2540 socket (soldered, mobile), while AMD uses Socket AM5 (desktop, upgradeable). Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

With no recorded head-to-head benchmark scores for the AMD Ryzen 7 7700X3D, the direct numerical comparison relies entirely on the Intel Core Ultra 5 336H's measured results. The Intel chip's Cinebench R23 multicore score of 23,991 and single-core score of 3,387 establish a baseline. Its R20 scores are 10,076 multicore and 1,422 single-core, while R15 scores are 2,418 multicore and 341 single-core.

The Passmark suite adds depth. The Intel chip scores 28,545 in multithread and 4,013 in single-thread (recorded twice, once as passmark_single_thread and once as passmark_singlethread, both identical). Data compression hits 280,340, data encryption 21,291, extended instructions 24,542, and prime number finding 299. Floating-point math reaches 82,415, integer math 62,070, physics 2,682, and random string sorting 34,402.

The Intel chip's nearest rivals provide context for these scores. The Intel Core i7-13700HX scores 34,554 on average, a 0.2% delta from the Ultra 5 336H's average of 34,485. The Intel Core i5-13450HX averages 34,333, a 0.4% delta in the Ultra 5's favor. The AMD Ryzen 7 3700X averages 34,260, a 0.7% delta, and the AMD Ryzen AI 7 350 averages 34,222, a 0.8% delta. The Ultra 5 336H sits just below the i7-13700HX and just above the i5-13450HX, meaning it trades blows with last-generation HX-class chips.

The AMD Ryzen 7 7700X3D has no average benchmark score recorded (0) and sits at the 50th percentile among all CPUs, though this percentile likely reflects incomplete data rather than actual performance. The Intel chip sits at the 84th percentile with an average benchmark score of 34,485. The database records zero wins for each processor in head-to-head tests, so all conclusions about the AMD part's performance come from its specifications.

The Verdict

From the recorded data, the Intel Core Ultra 5 336H is the measured performer. It holds every benchmark score in the database, and those scores place it in the 84th percentile of all CPUs, competitive with Intel's own HX-series parts from the previous generation. The 16 cores, 3 nm process, and 115.2 GB/s memory bandwidth give it a strong all-around profile for mobile computing.

The AMD Ryzen 7 7700X3D presents a different case. Its 96 MB L3 cache, 120 W TDP, and desktop socket indicate a processor built for sustained, cache-heavy workloads where the larger L3 reduces memory traffic. The 8 cores and 16 threads are fewer than the Intel chip's 16 cores, but the AMD part runs at a 4.00 GHz base clock versus the Intel's 1.90 GHz, suggesting higher sustained clocks per core. The boost clocks are close: 4.50 GHz for AMD, 4.60 GHz for Intel.

The verdict from the data: choose the Intel Core Ultra 5 336H for general-purpose mobile computing where measured performance matters. Choose the AMD Ryzen 7 7700X3D for desktop builds where the 96 MB L3 cache and AM5 platform offer a different performance envelope, even though the database lacks direct measurements to confirm its edge. The AMD part's 50th percentile ranking with no scores should be treated as incomplete data, not a performance judgment.
