AMD Ryzen 5 7400 vs NVIDIA DGX Spark (MediaTek AHJ11488B) Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the NVIDIA DGX Spark (MediaTek AHJ11488B) has no benchmark results in the database. Its average benchmark score is recorded as 0, and it holds no entries in the head-to-head benchmark table. The AMD Ryzen 5 7400, by contrast, has a full suite of PassMark results across eleven distinct tests, with an average benchmark score of 42055. This asymmetry means the quantitative comparison is entirely one-sided: the Ryzen 5 7400 registers wins in every category where data exists, while the DGX Spark contributes no measurable scores to compare.

The Ryzen 5 7400's strongest recorded result is in data compression, where it scores 261749. This figure dwarfs its other benchmark outputs, indicating a significant specialization in workloads that involve heavy data throughput and pattern recognition. In integer math, the processor delivers 64733, while floating point math reaches 40784. The extended instructions test produces 19924, and random string sorting completes at 31110. Data encryption scores 14865, and the multithread benchmark shows 21712. The single-thread score is 3248, which appears twice in the database under slightly different test names, confirming consistency in that measurement. Physics simulation scores 1150, and the find prime numbers test yields a raw score of 79.

Because the DGX Spark has no benchmark entries, the database cannot produce delta percentages or relative performance gaps. The nearest rivals for the Ryzen 5 7400 provide context for its standing: the AMD Ryzen 9 PRO 8945HS averages 41963, a delta of 0.2 percent, and the Intel Core i7-14700T averages 41914, a delta of 0.3 percent. The Intel Core i7-12850HX sits at 41779, a 0.7 percent gap, while the Intel Core i9-12900K reaches 42335, which is 0.7 percent higher than the Ryzen 5 7400. These narrow margins place the Ryzen 5 7400 in a competitive cluster where the difference between adjacent processors is under one percent.

The absence of DGX Spark benchmarks raises a question that the data cannot answer: whether its 20 cores and 3 nm process node translate into competitive performance. The percentile ranking for the DGX Spark is 50, meaning it sits at the median of all CPUs in the database, but without test scores, that ranking appears to be a placeholder rather than a computed value. The Ryzen 5 7400 holds an 88th percentile ranking, placing it well above the median and in the upper tier of recorded processors.

The Verdict

The data indicates that the AMD Ryzen 5 7400 is the only processor in this comparison with measurable benchmark performance. Its 88th percentile ranking versus all CPUs, combined with an average score of 42055, places it in a solid mid-to-upper performance band. The nearest rival data shows it trading blows with the Intel Core i9-12900K, trailing by 0.7 percent, while edging out the AMD Ryzen 9 PRO 8945HS by 0.2 percent and the Intel Core i7-14700T by 0.3 percent. These margins are slim, but they demonstrate that the Ryzen 5 7400 competes with established high-end desktop and mobile parts.

The NVIDIA DGX Spark presents a different profile entirely. With no benchmark scores recorded, its average of 0 and 50th percentile position offer no evidence of performance capability. The processor targets a different market segment, listed as Mobile, and carries a launch MSRP of $3999. That price point, combined with its 140 TDP and 20-core configuration, suggests a specialized compute device rather than a general-purpose desktop processor. The database contains no measurements to validate how that hardware configuration performs in practice.

For users selecting between these two based strictly on recorded data, the Ryzen 5 7400 is the only option with demonstrated performance. The DGX Spark cannot be evaluated on benchmarks because none exist in the database. The choice hinges on whether the DGX Spark's specifications, particularly its 3 nm process and quad-channel memory, matter more than verified test results. The data does not support a performance recommendation for the DGX Spark.

Architecture Differences

The two processors diverge fundamentally in architecture, process node, and design philosophy. The AMD Ryzen 5 7400 uses the Zen 4 architecture under the codename Raphael, built on a 5 nm process at TSMC. It packs 6,570 million transistors into a 71 mm² die. The NVIDIA DGX Spark uses the GB10 codename under the Spark generation, fabricated on a 3 nm process, also at TSMC, with a die size of 208 mm². Transistor count for the DGX Spark is not recorded in the database.

Core configurations differ sharply. The Ryzen 5 7400 has 6 cores and 12 threads, indicating simultaneous multithreading support. The DGX Spark has 20 cores and 20 threads, with no multithreading, so each core handles a single thread. Clock speeds favor the AMD part in base and boost: 3.30 GHz base and 4.30 GHz boost for the Ryzen 5 7400, versus 2.80 GHz base and 4.00 GHz boost for the DGX Spark. The DGX Spark compensates with a higher 140 TDP compared to the Ryzen 5 7400's 65 TDP, a reflection of its larger die and core count.

Cache hierarchies reveal different design priorities. The Ryzen 5 7400 allocates 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The DGX Spark allocates double the L1 at 128 KB per core and double the L2 at 2 MB per core, but its shared L3 is only 8 MB, half the Ryzen's capacity. This suggests the DGX Spark relies more on per-core cache locality, while the Ryzen 5 7400 provides a larger shared pool for multi-core workloads.

Memory architecture diverges as well. The Ryzen 5 7400 supports DDR5 over a dual-channel bus with 83.2 GB/s bandwidth and ECC memory support. The DGX Spark uses LPDDR5X over a quad-channel bus with 273.1 GB/s bandwidth, more than three times the Ryzen's throughput, but without ECC support. The memory bandwidth difference is substantial and likely reflects the DGX Spark's intended role in bandwidth-intensive compute tasks.

Other differences include PCIe support, where the Ryzen 5 7400 offers Gen 5 with 24 lanes from the CPU, while the DGX Spark lists PCIe as N/A. Integrated graphics differ: Radeon Graphics for the AMD part, and a GB20B "Blackwell" GPU for the NVIDIA part. The Ryzen 5 7400 has an unlocked multiplier, while the DGX Spark's multiplier is locked. The AMD processor uses the AM5 socket, while the DGX Spark's socket is not recorded. The Ryzen 5 7400 targets the desktop segment, the DGX Spark targets mobile.

Where Each One Wins

The AMD Ryzen 5 7400 wins in every benchmark category where data exists. Its data compression score of 261749 is the standout result, suggesting strong performance in archiving, database operations, and any workload that processes large volumes of repetitive data. The integer math score of 64733 and floating point math score of 40784 indicate balanced general-purpose compute capability. The multithread score of 21712, combined with the single-thread score of 3248, positions it as a capable all-rounder for desktop workloads. The extended instructions score of 19924 and random string sorting score of 31110 further support its versatility across different instruction types and data organization tasks.

The NVIDIA DGX Spark has no recorded wins because it has no benchmark data. Its specification sheet, however, suggests areas where it could potentially excel: the 273.1 GB/s memory bandwidth is more than triple the Ryzen 5 7400's 83.2 GB/s, which would benefit memory-bound tasks like large matrix operations or data streaming. The 20-core configuration with 2 MB L2 per core provides substantial per-core cache, which could help in workloads with high temporal locality. The integrated GB20B "Blackwell" graphics unit, while not benchmarked, represents a significant GPU capability that the Ryzen 5 7400's Radeon Graphics cannot match in raw compute terms. None of these advantages are confirmed by test scores, so they remain speculative based on specification differences.

The Ryzen 5 7400's unlocked multiplier and 65 TDP make it suitable for desktop systems where overclocking and power efficiency are priorities. Its 5 nm process and 71 mm² die suggest a compact, efficient design. The DGX Spark's 3 nm process and 208 mm² die indicate a more complex, power-hungry part aimed at specialized compute environments, but the database offers no performance evidence to support a specific use case.

Specification Differences

The two processors differ across nearly every recorded specification field. The Ryzen 5 7400 uses the Zen 4 architecture with the Raphael codename, while the DGX Spark uses the GB10 codename under the Spark generation, with no architecture listed.
