AMD Ryzen 5 9500F vs NVIDIA DGX Spark (MediaTek AHJ11488B) Comparison

Where Each One Wins

The AMD Ryzen 5 9500F and the NVIDIA DGX Spark (MediaTek AHJ11488B) occupy entirely different positions in the processor landscape, and the recorded benchmark data reflects that split. The Ryzen 5 9500F is a desktop processor with a full suite of PassMark test results, while the DGX Spark has no recorded benchmark scores in the database. This means every measured performance win belongs to the AMD part by default, but the comparison is not simply about who scores higher. It is about what each chip is designed to do.

The Ryzen 5 9500F wins decisively in conventional CPU workloads. Its PassMark single-thread score of 4258 and multithread score of 28312 place it in the 91st percentile of all CPUs in the database. The DGX Spark, with zero recorded benchmark scores, cannot be compared directly on those metrics. However, the DGX Spark is built for a different role. It is a mobile-market chip with an integrated GB20B "Blackwell" graphics processor, which suggests its strengths lie in GPU-accelerated tasks rather than general-purpose CPU math. The data shows no PassMark results for the DGX Spark, so the only way to differentiate the two is through architectural features and memory capabilities.

The DGX Spark wins in memory bandwidth. Its quad-channel LPDDR5X support delivers 273.1 GB/s, which is more than triple the Ryzen 5 9500F's dual-channel DDR5 bandwidth of 89.6 GB/s. That is a massive gap, and it points to workloads where memory throughput dominates. The Ryzen part wins in CPU core count efficiency for its power envelope: 6 cores and 12 threads at 65 W TDP versus 20 cores and 20 threads at 140 W TDP. The AMD chip delivers over 300 points per watt in multithread performance (28312 divided by 65), while the DGX Spark has no comparable measured output.

For users running traditional desktop applications, the Ryzen 5 9500F is the only part with measured results. For AI or GPU-centric workloads, the DGX Spark's integrated Blackwell graphics and 273.1 GB/s memory bandwidth are the relevant features, but the database lacks benchmark numbers to quantify that advantage.

Architecture Differences

The two processors come from different foundries, nodes, and design philosophies. The AMD Ryzen 5 9500F uses the Zen 5 architecture with the Granite Ridge codename, built on TSMC's 4 nm process. It packs 8,315 million transistors into a 70.6 mm² die. The NVIDIA DGX Spark uses the GB10 codename with a 3 nm process from TSMC, and its die is 208 mm². The AMD chip has a smaller die but the DGX Spark's larger die likely reflects the integrated Blackwell GPU.

Core configuration differs sharply. The Ryzen 5 9500F has 6 cores and 12 threads, meaning it supports simultaneous multithreading. The DGX Spark has 20 cores and 20 threads, with no SMT. Clock speeds favor AMD: the Ryzen part boosts to 5.00 GHz from a 3.80 GHz base, while the DGX Spark boosts to 4.00 GHz from a 2.80 GHz base. TDP reflects the DGX Spark's higher power draw at 140 W versus 65 W for the AMD chip.

Cache hierarchies are also distinct. The Ryzen 5 9500F provides 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. The DGX Spark offers 128 KB of L1 per core, 2 MB of L2 per core, but only 8 MB of shared L3. That is a notable difference: the AMD processor has four times the L3 cache, which benefits workloads with large working sets that fit in cache.

Memory support diverges completely. The Ryzen 5 9500F uses dual-channel DDR5 with 89.6 GB/s of bandwidth and supports ECC memory. The DGX Spark uses quad-channel LPDDR5X with 273.1 GB/s of bandwidth and no ECC support. The DGX Spark's memory bus is wider and faster, which is typical for integrated-GPU designs where the CPU and GPU share the same memory pool.

PCIe connectivity also separates them. The Ryzen 5 9500F has PCIe Gen 5 with 24 lanes from the CPU, enabling discrete GPUs and NVMe drives. The DGX Spark lists PCIe as "N/A", which indicates it is a self-contained mobile part without user-expandable PCIe slots. The AMD processor supports an unlocked multiplier for overclocking, while the DGX Spark is locked.

The DGX Spark integrates GB20B "Blackwell" graphics, whereas the Ryzen 5 9500F has no integrated graphics at all. That means the AMD part requires a discrete GPU for display output, while the DGX Spark has graphics built in. The DGX Spark targets the mobile segment; the Ryzen 5 9500F targets desktop.

The Verdict

The recorded data supports only one clear conclusion: the AMD Ryzen 5 9500F is the processor with measurable CPU performance, and the NVIDIA DGX Spark is a specialized mobile chip without benchmark results in the database. Users who need a desktop CPU for general computing, single-threaded tasks, or multithreaded workloads should look at the Ryzen 5 9500F. Its PassMark scores place it in the 91st percentile of all CPUs, and its nearest rivals include the AMD Ryzen 9 7900X, which scores 0.8% higher on average. That is a strong position for a 6-core part.

The DGX Spark, despite having no benchmark scores, offers features that the Ryzen part lacks: 273.1 GB/s of memory bandwidth, an integrated Blackwell GPU, and 20 cores. Those features point to AI inference or GPU-compute workloads where memory bandwidth and integrated graphics matter more than raw CPU integer math. However, without recorded scores, the database cannot confirm any performance advantage.

The Ryzen 5 9500F also offers flexibility through PCIe Gen 5 lanes, ECC memory support, and an unlocked multiplier. The DGX Spark is a closed mobile platform with no PCIe and no ECC. For a desktop builder, the AMD part is the only choice that fits a standard AM5 socket. For a device designer looking for a compact, high-bandwidth mobile chip with integrated graphics, the DGX Spark fills that role, but its performance remains unquantified in the database.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so there are no direct score comparisons between the two processors. Instead, the available data comes from the Ryzen 5 9500F's individual PassMark results, which stand as the only measured performance figures in this comparison.

The Ryzen 5 9500F delivers a PassMark multithread score of 28312, a single-thread score of 4258, and an average benchmark score of 52873. Its integer math score is 84198, floating point math is 56570, and extended instructions score is 26370. Data compression hits 325678, encryption reaches 15716, and random string sorting scores 34174. The physics test returns 1851, while prime number finding yields 220. These numbers place the chip in the 91st percentile of all CPUs.

The nearest rivals in the database show how competitive the Ryzen 5 9500F is. The AMD Ryzen AI Embedded P164 averages 52901, which is 0.1% higher. The Intel Xeon 634 averages 52974, 0.2% higher. The AMD EPYC 7313P averages 53206, 0.6% higher. The AMD Ryzen 9 7900X averages 53288, 0.8% higher. The Ryzen 5 9500F trails the closest rival by only 0.1%, and the gap to the Ryzen 9 7900X is under one percentage point despite that rival having more cores.

For the DGX Spark, the database records no benchmarks, no average score, and no nearest rivals. Its percentile rank is 50, which is the median position for all CPUs in the database, but that rank is based on no recorded scores. The only performance-relevant data for the DGX Spark is its memory bandwidth of 273.1 GB/s and its 20-core configuration. Those are architectural facts, not measured outcomes.

The largest "win" for the Ryzen 5 9500F in this comparison is its entire benchmark suite, since the DGX Spark has no scores to contest any of them. The largest "win" for the DGX Spark is its memory bandwidth, which is 183.5 GB/s higher than the AMD part, a 205% advantage. That bandwidth difference is the only quantitative edge the DGX Spark holds in the recorded data, and it matters for workloads that stream data through the memory controller rather than compute in the CPU cores.

In practical terms, the Ryzen 5 9500F is a measured performer in the top 9% of all CPUs, while the DGX Spark is an unmeasured mobile chip with a high-bandwidth memory subsystem and integrated graphics. The data supports the AMD part for any task that requires known CPU throughput, and it leaves the DGX Spark's actual compute capability as an open question that the database cannot answer.
