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

AMD Ryzen 5 7400 vs NVIDIA RTX Spark (MediaTek AHJ11488B)

The AMD Ryzen 5 7400 and the NVIDIA RTX Spark (MediaTek AHJ11488B) are fundamentally different processors. The Ryzen 5 7400 is an active desktop part with a full suite of benchmark results, while the RTX Spark is an unreleased mobile processor with no recorded benchmark scores. This means the comparison is largely one-sided: the Ryzen 5 7400 has measurable performance data, and the RTX Spark has only specifications. The recorded data shows the Ryzen 5 7400 delivers strong multi-threaded and single-threaded performance, while the RTX Spark’s specifications suggest a different design philosophy focused on mobile efficiency and memory bandwidth.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for these two processors. The Ryzen 5 7400 has eleven Passmark benchmark scores, while the RTX Spark has zero recorded benchmarks. Therefore, direct numerical comparisons are impossible. The analysis must rely on the Ryzen 5 7400’s scores and the RTX Spark’s specifications.

The Ryzen 5 7400’s average benchmark score is 42,055. This places it in the 88th percentile of all CPUs in the database. Its nearest rivals include the AMD Ryzen 9 PRO 8945HS with an average score of 41,963 (0.2% lower), the Intel Core i7-14700T with 41,914 (0.3% lower), the Intel Core i7-12850HX with 41,779 (0.7% lower), and the Intel Core i9-12900K with 42,335 (0.7% higher). These delta percentages show the Ryzen 5 7400 sits in a tight performance band, within 1% of multiple high-end desktop and mobile processors.

In the single-threaded Passmark test, the Ryzen 5 7400 scores 3,248. This is its most significant individual result, as it indicates strong per-core performance. The multi-threaded score is 21,712, which is roughly 6.7 times the single-thread score. This ratio is expected for a 6-core, 12-thread processor. The integer math score is 64,733, and the floating point math score is 40,784. The extended instructions score is 19,924, showing the processor’s ability to handle SIMD workloads. Data compression scores 261,749, while data encryption scores 14,865. The physics score is 1,150, and random string sorting scores 31,110. The find prime numbers score is 79.

The RTX Spark has no benchmark scores, so its performance cannot be quantified. The database shows its percentile as 50 and its average benchmark score as 0. This is not a verdict on its capability; it simply reflects the absence of recorded data. The processor is listed as unreleased, with a release date of 2025-12-31T17:00:00.000Z. Its production status is "unreleased," which explains the lack of benchmark results.

Where Each One Wins

The Ryzen 5 7400 wins in every measurable category because it has recorded performance data. Its multi-threaded score of 21,712 and single-threaded score of 3,248 indicate balanced performance across workloads. The data compression score of 261,749 is particularly high, suggesting strong performance in compression and decompression tasks. The integer math score of 64,733 indicates solid general-purpose computing capability. The floating point score of 40,784 shows competence in scientific and engineering workloads.

The RTX Spark wins in areas defined by its specifications rather than benchmarks. It has 20 cores and 20 threads, compared to the Ryzen 5 7400’s 6 cores and 12 threads. This core count advantage suggests the RTX Spark is designed for highly parallel workloads, but without benchmark data, this remains speculative. Its memory bandwidth of 273.1 GB/s is substantially higher than the Ryzen 5 7400’s 83.2 GB/s. This 3.3 times difference indicates the RTX Spark is designed for memory-intensive applications, possibly in AI or graphics contexts given its NVIDIA branding and integrated GB20B "Blackwell" graphics.

The RTX Spark’s TDP is 38 watts, compared to the Ryzen 5 7400’s 65 watts. This lower power draw suggests the RTX Spark is optimized for mobile or power-constrained environments. Its process node is 3 nm, versus 5 nm for the Ryzen 5 7400, indicating a more advanced manufacturing process. The die size of 208 mm² for the RTX Spark is larger than the 71 mm² of the Ryzen 5 7400, despite the smaller process node. This suggests the RTX Spark packs more transistors or more complex logic, though the transistor count is not recorded.

FAQ

Architecture Differences

The architectural designs are substantially different. The Ryzen 5 7400 uses the Zen 4 architecture with the codename Raphael. Its generation is listed as Ryzen 5 (Zen 4 (Raphael)). The RTX Spark has no recorded architecture, but its codename is N1X and its generation is Spark (GB10). The RTX Spark’s integrated graphics are identified as GB20B "Blackwell," indicating a connection to NVIDIA’s Blackwell graphics architecture, though this is not confirmed for the CPU portion.

The cache hierarchy differs significantly. The Ryzen 5 7400 has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The RTX Spark has 128 KB of L1 cache per core, 2 MB of L2 cache per core, and 8 MB of shared L3 cache. On a per-core basis, the RTX Spark has twice the L1 cache and twice the L2 cache. However, the Ryzen 5 7400 has double the L3 cache. The Ryzen 5 7400’s total L2 cache is 6 MB (1 MB per core, 6 cores), while the RTX Spark’s total L2 cache is 40 MB (2 MB per core, 20 cores). The RTX Spark’s larger per-core caches suggest a design aimed at reducing memory latency for individual cores.

The process nodes differ: 5 nm for the Ryzen 5 7400 and 3 nm for the RTX Spark, both from TSMC. The smaller node for the RTX Spark allows for more transistors in a given area, though the transistor count is not recorded. The die size is 208 mm² for the RTX Spark, much larger than the 71 mm² of the Ryzen 5 7400. This larger die, combined with the smaller process node, implies a significantly higher transistor count for the RTX Spark, though the exact figure is absent from the data.

Memory architecture is a major differentiator. The Ryzen 5 7400 uses dual-channel DDR5 with 83.2 GB/s bandwidth. The RTX Spark uses quad-channel LPDDR5X with 273.1 GB/s. The RTX Spark’s bandwidth is 3.3 times higher, which is a substantial advantage for memory-bound workloads. The Ryzen 5 7400 supports ECC memory, which is common for desktop and workstation use, while the RTX Spark does not, a typical trade-off for mobile memory.

The Ryzen 5 7400 has a base clock of 3.30 GHz and a boost clock of 4.30 GHz. The RTX Spark has a base clock of 1.70 GHz and a boost clock of 4.00 GHz. The base clock difference is large: the Ryzen 5 7400 runs at nearly twice the base frequency. However, the boost clocks are closer, with the Ryzen 5 7400 only 7.5% higher. The RTX Spark’s lower base clock and higher boost clock suggest a design that aggressively scales frequency under load but conserves power at idle.

The TDP is 65 watts for the Ryzen 5 7400 and 38 watts for the RTX Spark. This 27-watt difference is significant. The RTX Spark’s lower TDP, coupled with its higher core count, indicates a more power-efficient design per core, likely due to the 3 nm process node. However, the Ryzen 5 7400’s higher TDP allows for higher sustained clock speeds.

The Verdict

The recorded data shows the Ryzen 5 7400 is a measured, active desktop processor with an average benchmark score of 42,055 and an 88th percentile ranking. It delivers a single-thread score of 3,248 and a multi-thread score of 21,712, placing it within 1% of rivals like the Intel Core i9-12900K and the AMD Ryzen 9 PRO 8945HS. Its performance is well-documented and competitive for its class.

The RTX Spark is an unreleased mobile processor with no benchmark data. Its specifications indicate a different design: 20 cores, 20 threads, 3 nm process, 38 watt TDP, and 273.1 GB/s memory bandwidth. These figures suggest a processor optimized for parallel throughput and memory bandwidth in a power-constrained mobile environment. The lack of benchmark scores means its real-world performance cannot be verified.

For a buyer or analyst seeking a desktop processor with proven performance, the Ryzen 5 7400 is the only option with data. Its 6 cores and 12 threads, combined with a 4.30 GHz boost clock and 16 MB L3 cache, provide a balanced profile for general computing. The RTX Spark, with its 20 cores and quad-channel LPDDR5X, appears designed for specific workloads like AI inference or graphics processing, but no evidence supports this. The choice depends on the use case: the Ryzen 5 7400 for immediate, measurable desktop performance, or the RTX Spark for a speculative mobile part with advanced specifications but no recorded results.
