Intel Processor U300L vs NVIDIA DGX Spark (MediaTek AHJ11488B) Comparison

Head-to-Head Benchmarks

The database currently contains no recorded benchmark scores for either the Intel Processor U300L or the NVIDIA DGX Spark (MediaTek AHJ11488B). Both processors have an average benchmark score of zero and no entries in the head-to-head comparison table. Consequently, there are no measured performance deltas, no percentile rankings beyond the neutral 50th percentile mark for both, and no win counts to attribute to either part. This absence of data means any performance comparison must rely entirely on architectural and specification differences rather than empirical results. The benchmark database shows zero wins for each processor, indicating that no validated testing has been completed or published for these two SKUs at this time. Until benchmark runs populate the database, the relative performance between the U300L and the DGX Spark remains unquantified, and no percentage advantages can be cited from recorded measurements.

Architecture Differences

The two processors come from fundamentally different architectural lineages. The Intel Processor U300L is built on Raptor Lake architecture, with the codename Raptor Lake-PS, and belongs to the Intel Processor (Raptor Lake) generation. It uses a 10 nm process node manufactured at Intel's own foundry. The NVIDIA DGX Spark (MediaTek AHJ11488B) carries the codename GB10, belongs to the Spark (GB10) generation, uses a 3 nm process node fabricated by TSMC, and has a die size of 208 mm². The U300L has no recorded die size.

Cache hierarchies differ markedly. The U300L provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 8 MB of shared L3 cache. The DGX Spark provides 128 KB of L1 cache per core, 2 MB of L2 cache per core, and 8 MB of shared L3 cache. While the L3 caches match at 8 MB, the DGX Spark has larger L1 and L2 allocations per core, consistent with its higher core count and server-oriented positioning.

Memory architecture also diverges. The U300L supports DDR4 and DDR5 memory through a dual-channel bus, with no memory bandwidth figure recorded. The DGX Spark exclusively supports LPDDR5X memory through a quad-channel bus and achieves a recorded memory bandwidth of 273.1 GB/s. This bandwidth advantage is substantial and aligns with the DGX Spark's higher power envelope and integrated GPU capabilities.

PCI Express support further separates the two. The U300L provides Gen 4 connectivity with 8 lanes (CPU only). The DGX Spark lists PCIe as N/A, indicating it does not expose standard PCIe lanes from the CPU, relying instead on its integrated memory controller and Blackwell graphics. The integrated graphics solutions also differ: the U300L uses UHD Graphics 48EU, while the DGX Spark uses GB20B "Blackwell". Neither processor supports ECC memory.

Specification Differences

The recorded specifications show clear contrasts across nearly every field. Core counts differ substantially: 5 cores for the U300L versus 20 cores for the DGX Spark. Thread counts follow: 6 threads versus 20 threads. Base clocks are 1.20 GHz for the U300L and 2.80 GHz for the DGX Spark. Boost clocks are 4.40 GHz for the U300L and 4.00 GHz for the DGX Spark.

TDP ratings differ by an order of magnitude: 15 watts for the U300L versus 140 watts for the DGX Spark. The U300L uses an Intel Socket 1700, while the DGX Spark has no socket listed. Process nodes are 10 nm (Intel) versus 3 nm (TSMC). The DGX Spark has a recorded die size of 208 mm²; the U300L has none recorded.

Memory support: DDR4 and DDR5 for the U300L versus LPDDR5X for the DGX Spark. Memory buses: dual-channel versus quad-channel. Memory bandwidth: not recorded for the U300L versus 273.1 GB/s for the DGX Spark. PCIe: Gen 4, 8 lanes for the U300L versus N/A for the DGX Spark. Integrated graphics: UHD Graphics 48EU versus GB20B "Blackwell". Market segment for both is Mobile. Production status for both is Active. Release dates differ: 2024-04-07 for the U300L versus 2025-10-14 for the DGX Spark. Launch MSRP values are $107 for the U300L and $3999 for the DGX Spark. Neither has an unlocked multiplier. Part numbers are SRPEKSRPEM for the U300L and DSE1-275-A1 for the DGX Spark.

Where Each One Wins

Based solely on recorded specifications, the Intel Processor U300L wins on boost clock, delivering 4.40 GHz versus 4.00 GHz for the DGX Spark. It also offers a dramatically lower TDP of 15 watts, making it suitable for thermally constrained mobile designs. The U300L supports DDR4 and DDR5 memory, providing flexibility in memory choice. It uses a standard Intel Socket 1700, which simplifies integration into existing platforms. Its launch MSRP is $107, a fraction of the DGX Spark's $3999.

The NVIDIA DGX Spark (MediaTek AHJ11488B) wins on core count, thread count, base clock, process node, memory bandwidth, and cache per core. Its 20 cores and 20 threads dwarf the U300L's 5 cores and 6 threads. The 2.80 GHz base clock is more than double the U300L's 1.20 GHz. The 3 nm TSMC process node is two generations ahead of the 10 nm Intel node. The 273.1 GB/s memory bandwidth is a major advantage for memory-intensive workloads. The 128 KB L1 and 2 MB L2 per core are larger than the U300L's 80 KB and 1.25 MB per core. The DGX Spark also has a later release date and a larger die at 208 mm².

The benchmark database records no wins for either processor, so these use-case splits derive entirely from specification analysis. The U300L appears oriented toward low-power, cost-sensitive mobile devices where boost performance and upgradable memory matter. The DGX Spark appears oriented toward high-throughput processing with its wide core count, fast base clock, and enormous memory bandwidth, likely targeting AI or data-center-adjacent workloads given the "Spark" codename and Blackwell graphics.

The Verdict

The recorded data paints a clear contrast between two processors with different design goals. The Intel Processor U300L is a low-power, 15-watt mobile chip with 5 cores, a 4.40 GHz boost clock, DDR4/DDR5 support, and a $107 launch MSRP. It suits devices where power budgets are tight, socket compatibility matters, and sustained all-core throughput is secondary. The NVIDIA DGX Spark (MediaTek AHJ11488B) is a 140-watt, 20-core processor with a 273.1 GB/s memory bandwidth, a 3 nm process node, and a $3999 launch MSRP. It targets workloads that scale across many cores and demand high memory throughput.

Without benchmark scores in the database, no definitive performance winner can be declared. The specification sheet suggests the DGX Spark holds advantages in multi-core throughput, memory bandwidth, and manufacturing efficiency. The U300L counters with higher boost clock, lower power draw, and broader memory compatibility. Buyers seeking maximum parallel compute and memory bandwidth should favor the DGX Spark. Buyers prioritizing low power consumption, socket flexibility, and lower launch cost should favor the U300L. The absence of measured benchmark data means these conclusions rest on specifications alone, and the database will provide clearer guidance once benchmark results populate for both processors.
