Architecture Differences

The Intel Core i7-14701E is built on Intel’s Raptor Lake architecture, specifically the Raptor Lake-R refresh, using a 10 nm process node fabricated by Intel. The die size is 257 mm². It is a desktop-market part that uses Intel Socket 1700. The NVIDIA RTX Spark (MediaTek AHJ11488B) uses a different foundation: its codename is N1X, the generation is listed as Spark (GB10), and it is manufactured on a 3 nm process node by TSMC with a die size of 208 mm². This makes the NVIDIA part a significantly smaller die on a more advanced process, though it is targeted at the mobile segment rather than desktop.

The cache hierarchies also differ. The Intel part has an L1 cache of 80 KB per core, an L2 cache of 2 MB per core, and a shared L3 cache of 33 MB. The NVIDIA RTX Spark has a larger L1 cache at 128 KB per core, the same per-core L2 of 2 MB, but a much smaller shared L3 cache at 8 MB. In total cache capacity, the Intel part offers substantially more L3, which can benefit workloads with large working sets that rely on shared data.

Memory support diverges as well. The Intel Core i7-14701E uses a dual-channel memory bus and supports both DDR4 and DDR5 memory. The NVIDIA RTX Spark uses a quad-channel LPDDR5X bus, with a recorded memory bandwidth of 273.1 GB/s, a figure not available for the Intel part. The NVIDIA part has no PCIe lanes listed, whereas the Intel part provides Gen 5 with 16 lanes from the CPU.

Integrated graphics differ: the Intel part includes UHD Graphics 770, while the NVIDIA RTX Spark integrates GB20B "Blackwell" graphics. Both parts have locked multipliers, meaning neither supports unlocked overclocking. The NVIDIA part is unreleased, while the Intel part is active in production.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons between the Intel Core i7-14701E and the NVIDIA RTX Spark are not present in the database. The head-to-head benchmark list is empty, and the win counts for both parts are zero. However, the Intel part has a full set of recorded benchmark scores, while the NVIDIA part has none. Therefore, all quantitative performance analysis must rely on the Intel part’s measurements alone, with the NVIDIA part’s performance remaining unmeasured.

For the Intel Core i7-14701E, the recorded Cinebench scores are as follows: Cinebench R15 multi-core scores 2237, single-core 315; Cinebench R20 multi-core scores 9321, single-core 1315; Cinebench R23 multi-core scores 22195, single-core 3133. In PassMark tests, the Intel part records multi-thread performance at 26112, single-thread at 4305, integer math at 81325, floating-point math at 61873, extended instructions at 18528, data compression at 282939, data encryption at 14862, find prime numbers at 176, physics at 2399, and random string sorting at 29158. The average benchmark score across all recorded tests is 33206.

The Intel part’s percentile vs all CPUs is 83, placing it above the majority of processors in the database. Its nearest rivals, based on average score, are the AMD Ryzen 9 PRO 6950H at 33201 with a 0% delta, the AMD Ryzen 5 8645HS at 33244 with a delta of -0.1%, the AMD Ryzen 7 7745HX at 33091 with a delta of 0.3%, and the Intel Core i7-13650HX at 33089 with a delta of 0.4%. These deltas indicate that the Intel Core i7-14701E is effectively tied with these four rivals, within a range of less than half a percent. In practical terms, the data shows the Intel part sits in a tight performance cluster around the 33,000 average score mark, with no single rival holding a material advantage.

Specification Differences

The two processors differ in nearly every specification field. The Intel Core i7-14701E has 8 cores and 16 threads; the NVIDIA RTX Spark has 20 cores and 20 threads. The Intel base clock is 2.60 GHz versus 1.70 GHz for the NVIDIA part, and the Intel boost clock is 5.40 GHz versus 4.00 GHz. Thermal design power is 65 W for the Intel part and 38 W for the NVIDIA part, meaning the Intel processor carries a higher power envelope.

The Intel part uses Intel Socket 1700, while the NVIDIA part has no socket listed. Architecture is Raptor Lake for Intel and null for NVIDIA, though the codename is N1X for NVIDIA. The process node is 10 nm for Intel (foundry: Intel) and 3 nm for NVIDIA (foundry: TSMC). Die size is 257 mm² for Intel and 208 mm² for NVIDIA.

Cache specifications: Intel L1 is 80 KB per core, L2 is 2 MB per core, L3 is 33 MB shared. NVIDIA L1 is 128 KB per core, L2 is 2 MB per core, L3 is 8 MB shared. Memory support is DDR4 and DDR5 for Intel, LPDDR5X for NVIDIA. Memory bus is dual-channel for Intel and quad-channel for NVIDIA. Memory bandwidth is not recorded for Intel, but is 273.1 GB/s for NVIDIA. ECC memory is supported on Intel, not on NVIDIA. PCIe is Gen 5 with 16 lanes for Intel, and N/A for NVIDIA. Integrated graphics are UHD Graphics 770 for Intel and GB20B "Blackwell" for NVIDIA. Market segment is Desktop for Intel and Mobile for NVIDIA. Production status is Active for Intel and unreleased for NVIDIA. Release date is 2024-06-30 for Intel and 2025-12-31 for NVIDIA. The part number is Q49FSRNJK for Intel and GSE1-675-A1 for NVIDIA.

The NVIDIA RTX Spark has 20 threads with 20 cores, meaning each core has exactly one thread, whereas the Intel part uses Hyper-Threading to double its thread count from 8 to 16. The NVIDIA part’s higher core count does not translate into a thread advantage due to the lack of simultaneous multithreading.

The Verdict

The recorded data shows a clear asymmetry between these two parts. The Intel Core i7-14701E has a full complement of benchmark scores, an average score of 33206, and a percentile of 83. The NVIDIA RTX Spark has no benchmark scores and an average score of 0, with a percentile of 50. The database cannot substantiate any performance claim for the NVIDIA part because no measurements exist.

For users selecting a desktop processor with proven multi-threaded and single-threaded performance, the Intel Core i7-14701E delivers measured results across Cinebench R15, R20, R23, and PassMark suites. Its nearest rivals sit within 0.4% of its average score, confirming it is competitive with a specific set of AMD and Intel mobile and desktop parts. The Intel part also offers ECC memory support, a feature absent from the NVIDIA part, and its 33 MB shared L3 cache is substantially larger.

For the NVIDIA RTX Spark, the data indicates an unreleased mobile processor with a higher core count, a smaller process node, a lower power envelope, and quad-channel LPDDR5X memory bandwidth of 273.1 GB/s. Its 20 cores and 20 threads suggest a design aimed at parallel throughput, but without recorded benchmarks, the database cannot quantify its performance relative to the Intel part. The mobile segment, unreleased status, and lack of PCIe support further differentiate it as a fundamentally different product category.

The verdict from the data: the Intel Core i7-14701E is the only one of the two with measurable performance, so it is the only part for which benchmark-based selection is possible. The NVIDIA RTX Spark remains an unmeasured, unreleased mobile processor whose specifications point to a different use case, but whose performance cannot be assessed from the database.
