Intel Core 5 315 vs NVIDIA RTX Spark (MediaTek AHJ11488B) Comparison

The Verdict

The database presents a unique comparison: the Intel Core 5 315 is a fully measured, shipping mobile processor, while the NVIDIA RTX Spark (MediaTek AHJ11488B) is an unreleased part with no recorded benchmark scores. The Intel chip has an average benchmark score of 18188 and sits at the 72nd percentile of all CPUs. The RTX Spark has an average score of 0 and a 50th percentile ranking, purely by virtue of having no measurements in the database. The core architectural data, however, reveals a stark contrast: the RTX Spark packs 20 cores and 20 threads against the Intel's 6 cores and 6 threads, with a quad-channel memory bus delivering 273.1 GB/s versus the Intel's single-channel 59.7 GB/s. The data cannot declare a performance winner because the RTX Spark has no recorded scores. The Intel Core 5 315 is the only choice for anyone needing verified benchmark results today, while the RTX Spark's specifications suggest a fundamentally different, higher-bandwidth design that the database has yet to measure. The Intel chip is active in production; the RTX Spark is unreleased.

FAQ

Architecture Differences

The two processors diverge sharply in their underlying designs. The Intel Core 5 315 uses the Wildcat Lake codename and belongs to the Core 5 (Wildcat Lake) generation. It is built on a 3 nm process at Intel's own foundry. The RTX Spark uses the N1X codename, belongs to the Spark (GB10) generation, and is fabricated by TSMC on a 3 nm process. Both are mobile segments, and neither has an unlocked multiplier.

The compute resources differ by more than a factor of three. The Intel part offers 6 cores and 6 threads, meaning no hyper-threading or equivalent. The RTX Spark offers 20 cores and 20 threads, also without extra threads. The cache hierarchy is structured differently as well. The Intel Core 5 315 has a 192 KB L1 cache, 2.5 MB L2, and 6 MB of shared L3. The RTX Spark specifies 128 KB of L1 per core, 2 MB of L2 per core, and 8 MB of shared L3. Given its 20 cores, the per-core L2 allocation on the RTX Spark totals far more aggregate cache, though the database does not list a total L2 figure. The die size for the RTX Spark is listed at 208 mm², while no die size is recorded for the Intel chip.

Memory architecture is another major split. The Intel Core 5 315 supports DDR5 and LPDDR5X over a single-channel bus, yielding 59.7 GB/s of bandwidth. The RTX Spark supports only LPDDR5X, but over a quad-channel bus rated at 273.1 GB/s. Neither chip supports ECC memory. PCIe support also differs: the Intel part exposes Gen 4 with 6 lanes (CPU only), while the RTX Spark lists PCIe as N/A.

The integrated graphics are entirely different. The Intel chip uses Intel Xe3 Graphics with 2 Xe cores. The RTX Spark uses a GB20B "Blackwell" GPU. The database does not provide any graphics benchmark scores for either, so the comparison is limited to naming and architecture.

Specification Differences

The recorded specification fields show clear contrasts. Core count: 6 on the Intel, 20 on the RTX Spark. Thread count: 6 versus 20. Base clock: 1.50 GHz on the Intel, 1.70 GHz on the RTX Spark. Boost clock: 4.40 GHz on the Intel, 4.00 GHz on the RTX Spark. TDP: 15 watts for the Intel, 38 watts for the RTX Spark. Socket: Intel BGA 1516 for the Intel part, no socket listed for the RTX Spark.

Process node: both are 3 nm, but the foundry is Intel for the Core 5 315 and TSMC for the RTX Spark. Cache: the Intel lists L1 of 192 KB, L2 of 2.5 MB, and L3 of 6 MB shared; the RTX Spark lists L1 of 128 KB per core, L2 of 2 MB per core, and L3 of 8 MB shared. Memory support: DDR5 and LPDDR5X for the Intel, LPDDR5X only for the RTX Spark. Memory bus: single-channel versus quad-channel. Memory bandwidth: 59.7 GB/s versus 273.1 GB/s. PCIe: Gen 4, 6 lanes (CPU only) versus N/A.

Integrated graphics: Intel Xe3 Graphics (2 Xe) versus GB20B "Blackwell". Production status: Active versus unreleased. Release date: 2026-04-15 for the Intel, 2025-12-31 for the RTX Spark. Launch MSRP: $340 for the Intel, none listed for the RTX Spark. Part number: SAEFC for the Intel, GSE1-675-A1 for the RTX Spark. Die size: not recorded for the Intel, 208 mm² for the RTX Spark. The RTX Spark has no benchmark scores, no average benchmark score, and no rivals; the Intel has all three.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two processors. The Intel Core 5 315 has a full suite of 17 recorded benchmark scores; the RTX Spark has none. The comparison is therefore limited to the Intel's measured results and the RTX Spark's theoretical specifications.

The Intel Core 5 315's recorded scores show a clear single-thread and multi-thread profile. In Cinebench R15, it scores 1308 multi-core and 184 single-core. In Cinebench R20, it scores 5452 multi-core and 769 single-core. In Cinebench R23, it scores 12981 multi-core and 1832 single-core. PassMark results include 146143 in data compression, 11119 in data encryption, 13143 in extended instructions, 112 in find prime numbers, 42441 in floating point math, 31690 in integer math, 15272 in multithread, 1163 in physics, 17551 in random string sorting, and 4021 in single thread.

The nearest rival data anchors the Intel chip's standing. The AMD EPYC 9274F averages 18189, the Intel Core i7-9700 averages 18180, the Intel Core i7-1365U averages 18177, and the AMD Ryzen 7 5700U averages 18176. The Core 5 315 at 18188 is effectively tied with the EPYC 9274F and sits within 0.1% of the other three. This indicates that, despite its low TDP of 15 watts and modest 6-core configuration, the Intel chip lands in the same average performance band as a 24-thread server part and a desktop i7 from an older generation.

The RTX Spark, with 20 cores and a 273.1 GB/s memory bus, would likely excel in memory-throughput-sensitive workloads if its specifications translate to performance. The database provides no scores to confirm or refute that expectation. The Intel chip's 59.7 GB/s bandwidth is a hard constraint for any workload that saturates memory, while the RTX Spark's quad-channel design offers 4.6 times the rated bandwidth. Without measurements, the magnitude of any real-world advantage remains unknown.

Where Each One Wins

Based strictly on recorded data, the Intel Core 5 315 wins in every measurable category because it is the only one of the two with scores. It wins in verified Cinebench and PassMark results, in production status, and in having a defined competitive position via its nearest rivals. Its 15-watt TDP also suggests efficiency relative to the RTX Spark's 38-watt TDP, though the database does not include power efficiency benchmarks.

The NVIDIA RTX Spark wins on paper in raw core count, with 20 cores versus 6, and in memory bandwidth, with 273.1 GB/s versus 59.7 GB/s. It also has a higher base clock at 1.70 GHz versus 1.50 GHz, though it loses the boost clock comparison at 4.00 GHz versus 4.40 GHz. Its 8 MB of shared L3 exceeds the Intel's 6 MB of shared L3. Its per-core L2 allocation of 2 MB is substantially larger than the Intel's total 2.5 MB L2, suggesting a design aimed at high per-core cache locality.

The Intel part is the only one with any recorded evidence of real-world performance. The RTX Spark is a specification sheet with no measurements. For workloads that depend on memory throughput, such as large data movement or certain AI tasks, the RTX Spark's quad-channel 273.1 GB/s bus is a notable specification advantage. For workloads that depend on single-thread speed, the Intel chip's 4.40 GHz boost clock is the higher figure. The database does not include any benchmark results for the RTX Spark, so any claim of a definitive win for either chip beyond the recorded Intel scores would be speculation. The Intel Core 5 315 is the measured part, and the RTX Spark remains an unmeasured design awaiting evaluation.
