AMD Ryzen 5 5500X3D vs NVIDIA RTX Spark (MediaTek AHJ11488B) Comparison

Head-to-Head Benchmarks

The recorded data contains no shared benchmark results between the AMD Ryzen 5 5500X3D and the NVIDIA RTX Spark (MediaTek AHJ11488B). The head-to-head benchmark array is empty, and the NVIDIA RTX Spark has no benchmark scores listed in the database. Consequently, no direct performance comparison can be made using measured scores.

The AMD Ryzen 5 5500X3D has a full set of PassMark results. Its average benchmark score is 37018, placing it in the 85th percentile among all CPUs. In single-thread performance, it scores 2941. The multithread score is 20363. Its integer math score is 60033, and floating point math is 34511. Data compression yields a score of 230392, while data encryption is 13967. Extended instructions score 15925, find prime numbers 170, physics 2282, and random string sorting 23675.

The NVIDIA RTX Spark shows an average benchmark score of 0 with no individual test results. Its percentile ranking is 50, but this is based on no measured data. With no scores recorded, the database cannot establish any winning margin for either processor in a direct comparison. The wins counter for each item is zero. Any statement about which part leads in a given workload is unsupported by the available measurements.

Architecture Differences

The two devices diverge substantially in architecture. The AMD Ryzen 5 5500X3D uses Zen 3 architecture with the Vermeer codename, built on a 7 nm process at TSMC. It has 6 cores and 12 threads. The NVIDIA RTX Spark uses the N1X codename with a Spark (GB10) generation designation, built on a 3 nm process, also at TSMC. It has 20 cores and 20 threads, meaning it does not support simultaneous multithreading.

Cache hierarchies differ sharply. The AMD part provides 64 KB of L1 cache per core, 512 KB of L2 per core, and a large 96 MB shared L3 cache. The NVIDIA RTX Spark offers 128 KB of L1 per core, 2 MB of L2 per core, and only 8 MB of shared L3. The Ryzen's 96 MB shared L3 is a defining feature, while the Spark's larger per-core L1 and L2 are notable for its core count.

The process node gap is significant: 7 nm for the Ryzen versus 3 nm for the Spark. The die size also differs, with the Ryzen at 74 mm² and the Spark at 208 mm². The Spark integrates GB20B "Blackwell" graphics, while the Ryzen has no integrated graphics. The Ryzen supports ECC memory; the Spark does not.

The Ryzen is a desktop part with AMD Socket AM4, while the Spark is a mobile part with no socket listed. The Ryzen uses DDR4 memory with dual-channel support and 51.2 GB/s bandwidth. The Spark uses LPDDR5X with quad-channel support and 273.1 GB/s bandwidth. The Ryzen provides PCIe Gen 4 with 20 lanes (CPU only); the Spark lists PCIe as N/A.

Production status also differs. The Ryzen is active and released, while the Spark is unreleased. The Ryzen's release date is 2025-06-04, and the Spark's is 2025-12-31. The Ryzen's part number is 100-000001504, and the Spark's is GSE1-675-A1.

Where Each One Wins

The AMD Ryzen 5 5500X3D clearly wins in any scenario requiring measured performance data. It has recorded scores across all PassMark tests, and its 85th percentile ranking indicates it sits above the majority of CPUs in the database. Its nearest rivals provide context: the AMD Ryzen 5 5600F scores 36945, which is 0.2% lower; the AMD Ryzen AI 7 PRO 450 scores 37093, 0.2% higher; the Intel Core Ultra 5 225 scores 36938, 0.2% lower; and the Intel Core i9-12900T scores 37112, 0.3% higher. The Ryzen 5 5500X3D's average score of 37018 places it effectively in a tight cluster with these competitors, all within a 0.5% band. Its 96 MB shared L3 cache and 12 threads make it suited to workloads that benefit from large cache capacity, such as data compression, where it scores 230392, and integer math, at 60033.

The NVIDIA RTX Spark has no benchmark results, so it cannot be said to win any measured workload. Its 20 cores and 20 threads, along with 273.1 GB/s memory bandwidth, suggest capacity for parallel throughput, but the database contains no scores to confirm this. Its 3 nm process and 208 mm² die size indicate a modern design, and the integrated GB20B "Blackwell" graphics give it a feature the Ryzen lacks entirely. The Spark's LPDDR5X memory with quad-channel support offers more than five times the bandwidth of the Ryzen's DDR4 setup, but no benchmark confirms whether this translates into real performance.

For single-thread tasks, the Ryzen's score of 2941 is the only recorded data point. For multithread workloads, the Ryzen's 20363 is likewise the only recorded figure. The Spark's lack of scores means the only "win" it can claim is on paper: core count, bandwidth, process node, and integrated graphics. The Ryzen wins on every measurable benchmark in the database.

The Verdict

The data supports a clear conclusion: the AMD Ryzen 5 5500X3D is the only one of the two with any recorded performance measurements. Every benchmark score in this comparison belongs to the Ryzen. Its average score of 37018 and 85th percentile ranking give it a concrete position in the database, while the NVIDIA RTX Spark's average score of 0 and empty benchmark list provide no basis for a performance claim.

The Ryzen 5 5500X3D is the part to choose when measured performance matters. It delivers a complete suite of PassMark scores, with particularly strong results in data compression (230392) and integer math (60033). Its 96 MB shared L3 cache is a distinctive asset. Its nearest rivals sit within 0.3% of its average score, confirming it is competitive in its immediate class.

The NVIDIA RTX Spark is a different kind of product: a mobile, unreleased part with 20 cores, 20 threads, a 3 nm process, and integrated Blackwell graphics. It offers advantages in core count, memory bandwidth (273.1 GB/s), and power efficiency (38 W TDP versus 105 W). But none of these advantages are confirmed by benchmark scores in the database. The Spark also lacks a socket, lists PCIe as N/A, and has not been released.

For users selecting between these two based on the database, the Ryzen 5 5500X3D is the only option with verified results. The Spark's specifications suggest a capable mobile processor, but until its benchmark data is recorded, it cannot be ranked against the Ryzen. The Ryzen's active status, released date, and full benchmark coverage make it the defensible choice in any analysis grounded in the recorded data.
