AMD Ryzen 7 8840HX vs NVIDIA RTX Spark (MediaTek AHJ11488B) Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Ryzen 7 8840HX and the NVIDIA RTX Spark (MediaTek AHJ11488B) presents a unique analytical situation. The database contains a complete benchmark profile for the AMD processor, while the NVIDIA part currently has no recorded benchmark scores. The head-to-head comparison section is therefore empty, with zero wins recorded for each side. This does not indicate parity; it reflects an absence of measurement data for the unannounced NVIDIA product.

For the AMD Ryzen 7 8840HX, the available metrics paint a clear picture of its compute capabilities. In Cinebench R23, the processor scores 25,265 points in the multi-core test and 1,857 points in the single-core test. These figures place it in the 94th percentile of all CPUs in the database, indicating strong overall performance relative to the broader processor landscape. The average benchmark score across all recorded tests is 71,797 points.

Looking at the PassMark suite, the Ryzen 7 8840HX shows notable strengths in specific workloads. The integer math test returns a score of 146,506, while floating point math reaches 86,747. Data compression scores 496,427, and data encryption completes at 29,919. Extended instruction processing achieves 36,527, and the find prime numbers test produces a score of 304. The multi-thread rating is 41,732, with a single-thread score of 3,958. Additional tests include physics at 2,185 and random string sorting at 57,971.

The nearest rivals in the database provide context for the AMD chip's standing. The Intel Core Ultra 7 265KF posts an average score of 71,910, which is 0.2% higher than the Ryzen 7 8840HX's 71,797. The Intel Xeon Platinum 8270 averages 71,370, placing it 0.6% behind the AMD part. Both the Intel Xeon 6517P and Intel Xeon 6724P sit at 72,350 and 72,396 respectively, each trailing the Ryzen 7 8840HX by 0.8%. These deltas are narrow, showing that the AMD processor competes within a tight band of high-end desktop and server parts.

Because the NVIDIA RTX Spark has no entries in the benchmark database, no direct score comparisons can be drawn. The absence of head-to-head results, combined with zero wins for either item, means the data cannot confirm a performance advantage for one over the other. The AMD part's percentile ranking and average score stand as the only quantitative performance evidence available.

Where Each One Wins

The AMD Ryzen 7 8840HX demonstrates clear strengths in multi-threaded and mixed-workload scenarios based on its recorded benchmarks. The 12-core, 24-thread configuration with a 5.10 GHz boost clock delivers a Cinebench R23 multi-core score of 25,265, which is a strong indicator for rendering, scientific computing, and other parallel tasks. The PassMark multi-thread score of 41,732 reinforces this capability. The data compression result of 496,427 is particularly high, suggesting efficient handling of archive operations and data processing pipelines.

For single-threaded performance, the Ryzen 7 8840HX achieves a Cinebench R23 score of 1,857 and a PassMark single-thread score of 3,958. These figures indicate solid responsiveness in applications that rely on one or two cores, such as legacy software or lightly threaded workloads. The extended instructions score of 36,527 points to good SIMD and vector processing capability, which benefits multimedia encoding and certain scientific workloads.

The NVIDIA RTX Spark, with its 20 cores and 20 threads running at a 1.70 GHz base and 4.00 GHz boost clock, has no benchmark scores in the database. Therefore, the data cannot identify any workload category where it wins. The processor's architecture details, such as the N1X codename and GB10 generation, along with a 3 nm process node, suggest a modern design, but without measured results, any claim of victory in specific applications is unsupported.

The AMD part's memory bandwidth of 83.2 GB/s over a dual-channel DDR5 interface is modest compared to the NVIDIA part's 273.1 GB/s over quad-channel LPDDR5X. However, the database does not include benchmarks that isolate memory bandwidth, so this specification difference does not translate into recorded wins. The AMD processor's 64 MB shared L3 cache is substantially larger than the NVIDIA part's 8 MB shared L3, which may influence cache-sensitive workloads, but again, no benchmark confirms this.

Architecture Differences

The AMD Ryzen 7 8840HX is built on the Zen 4 architecture with the Dragon Range codename, part of the 8000 series. It uses a 5 nm process node fabricated by TSMC, with a transistor count of 13,140 million across a die size of 2x 71 mm². The processor has 12 cores and 24 threads, with a base clock of 2.90 GHz and a boost clock of 5.10 GHz. The thermal design power is 55 watts, and it uses the AMD Socket FL1. The multiplier is unlocked, allowing overclocking on supported platforms.

The cache hierarchy for the AMD part is substantial. Each core has 64 KB of L1 cache and 1 MB of L2 cache, with 64 MB of shared L3 cache. This large L3 pool is typical of high-end desktop derivatives and supports the multi-threaded performance seen in the benchmarks. Memory support is dual-channel DDR5 with a bandwidth of 83.2 GB/s, and ECC memory is not supported. The PCIe interface is Gen 5 with 28 lanes available from the CPU. Integrated graphics are handled by the Radeon 610M.

The NVIDIA RTX Spark (MediaTek AHJ11488B) presents a different architectural profile. The codename is N1X, and the generation is listed as Spark (GB10). It is built on a 3 nm process node from TSMC, with a die size of 208 mm². The processor has 20 cores and 20 threads, with a base clock of 1.70 GHz and a boost clock of 4.00 GHz. The thermal design power is 38 watts, which is lower than the AMD part. The multiplier is locked, and the socket is not specified in the database.

Cache and memory configurations for the NVIDIA part differ markedly from the AMD chip. Each core has 128 KB of L1 cache and 2 MB of L2 cache, but the shared L3 cache is only 8 MB. This is a significant reduction compared to the AMD part's 64 MB. Memory support is LPDDR5X over a quad-channel bus, delivering a bandwidth of 273.1 GB/s, which is more than three times the AMD part's figure. The PCIe interface is marked as N/A, suggesting an integrated or non-expandable design. Integrated graphics are provided by the GB20B "Blackwell" GPU block.

The process node difference is notable: the NVIDIA part uses 3 nm versus the AMD part's 5 nm, which typically allows higher transistor density and improved power efficiency. However, the database does not list a transistor count for the NVIDIA part. The AMD part has more threads (24 versus 20) and a higher boost clock (5.10 GHz versus 4.00 GHz). The NVIDIA part has more physical cores (20 versus 12), but without simultaneous multi-threading, its thread count is lower. The memory bandwidth advantage for the NVIDIA part is pronounced, but the smaller L3 cache may limit performance in workloads that benefit from large shared caches.

The Verdict

The benchmark data clearly supports the AMD Ryzen 7 8840HX as the only processor with measurable performance. With a 94th percentile ranking and an average benchmark score of 71,797, it demonstrates competitive standing against Intel parts such as the Core Ultra 7 265KF (0.2% lower), Xeon Platinum 8270 (0.6% higher), Xeon 6517P (0.8% lower), and Xeon 6724P (0.8% lower). The AMD part's multi-core Cinebench score of 25,265 and single-core score of 1,857 provide a solid foundation for general-purpose computing.

The NVIDIA RTX Spark has no recorded benchmarks, no average score, and no rival comparisons. Its production status is listed as unreleased, with a release date of 2025-12-31. The database cannot rate its performance, and the 50th percentile assigned to it is a placeholder value, not a measured result. Any selection between these two parts based on data must favor the AMD processor, simply because it has verifiable performance metrics.

For users who rely on multi-threaded applications, the AMD Ryzen 7 8840HX with its 12 cores and 24 threads, combined with a 64 MB L3 cache, is the data-backed choice. The PassMark integer math score of 146,506 and floating point score of 86,747 indicate robust compute throughput. The data compression score of 496,427 is exceptional and suggests strong performance in archival and storage-related tasks.

The NVIDIA RTX Spark, with its 20 cores and 38 watt TDP, along with quad-channel LPDDR5X memory delivering 273.1 GB/s, may offer advantages in memory bandwidth and power efficiency, but these are architectural specifications, not measured outcomes. The database records no wins for this part in any benchmark category. Consequently, the verdict from the data is clear: the AMD Ryzen 7 8840HX is the only processor with demonstrated performance, and it should be selected where verified benchmarks are required.
