Intel Core 9 273PE vs NVIDIA RTX Spark (MediaTek AHJ11488B) Comparison

Head-to-Head Benchmarks

The Intel Core 9 273PE and NVIDIA RTX Spark (MediaTek AHJ11488B) occupy very different positions in the database. The Intel part has a full suite of recorded benchmark results, while the RTX Spark currently has no benchmark scores logged. This makes direct numerical comparison impossible for most workloads. The database lists zero head-to-head benchmark entries between the two processors, and the win count stands at zero for each side.

The Intel Core 9 273PE delivers a Cinebench R23 multi-core score of 31,288 and a single-core score of 4,417. In Cinebench R20, it records 13,140 multi-core and 1,855 single-core. The older Cinebench R15 run shows 3,153 multi-core and 445 single-core. These scores place the processor at the 90th percentile among all CPUs in the database.

PassMark results for the Intel part include a multi-thread score of 36,810 and a single-thread score of 3,650. Integer math reaches 139,410, while floating-point math hits 107,884. The extended instructions test records 24,630, and data encryption scores 22,719. Data compression reaches 405,885, random string sorting scores 45,098, find prime numbers returns 203, and physics scores 3,120.

The RTX Spark has no recorded scores in any benchmark category. Its average benchmark score is listed as zero, and it holds the 50th percentile among all CPUs. The absence of data means the database cannot establish a performance baseline for this processor. Any claims about its relative speed would require measurement, which has not yet occurred.

The nearest rivals for the Intel Core 9 273PE provide context for its average benchmark score of 49,845. The AMD Ryzen AI Max+ 388 scores 49,796, which is 0.1 percent lower. The Intel Core i5-14600KF scores 49,394, a 0.9 percent deficit. The Intel Core i9-13980HX scores 50,398, putting it 1.1 percent ahead of the 273PE. The AMD Ryzen AI 9 HX PRO 370 scores 50,448, which is 1.2 percent higher.

These small deltas show the Intel Core 9 273PE sits in a tightly contested performance band. The 0.1 percent gap to the Ryzen AI Max+ 388 is within measurement noise. The 1.1 and 1.2 percent gaps to the i9-13980HX and Ryzen AI 9 HX PRO 370 respectively indicate the 273PE trails those parts by a narrow margin in aggregate scoring.

The RTX Spark has no nearest rivals listed in the database, which reflects its lack of measured results. Without benchmark data, the database cannot compute percentile rankings beyond the default 50th percentile or produce an average score other than zero.

Where Each One Wins

The Intel Core 9 273PE wins in every category where benchmark data exists, simply because the RTX Spark has no recorded results. The database shows 0 wins for the RTX Spark and 0 wins for the Intel part in head-to-head entries, but the Intel processor has a complete benchmark profile across rendering, encryption, compression, and math workloads.

For multi-threaded productivity, the Intel Core 9 273PE delivers a Cinebench R23 multi-core score of 31,288. This indicates strong parallel performance for rendering and compilation tasks. The PassMark multi-thread score of 36,810 reinforces this interpretation. The R20 multi-core score of 13,140 and R15 multi-core score of 3,153 both point to consistent scaling across different render workloads.

Single-thread performance is equally well documented. The Cinebench R23 single-core score of 4,417 places the Intel part at a level appropriate for lightly threaded applications. The R20 single-core score of 1,855 and R15 single-core score of 445 follow the same pattern. PassMark single-thread confirms this with a score of 3,650.

The math workloads show specific strengths. Integer math at 139,410 suggests strong general arithmetic throughput. Floating-point math at 107,884 indicates solid scientific and simulation capability. Extended instructions at 24,630 covers SIMD-heavy code paths. Data encryption at 22,719 and data compression at 405,885 round out the security and storage workload picture.

The RTX Spark, by contrast, has no wins in any category because no measurements exist. Its 20 cores and 20 threads suggest a design that could handle parallel workloads, but the database cannot confirm this without scores. Its 3 nm process node and TSMC foundry indicate a modern manufacturing approach, yet process geometry alone does not determine performance.

The use-case split is therefore one-sided. The Intel Core 9 273PE is a measured quantity for desktop workloads ranging from rendering to encryption. The RTX Spark remains an unmeasured variable, suitable only for qualitative discussion based on its specifications.

Architecture Differences

The processor has 12 cores and 24 threads, enabling simultaneous multithreading. Its base clock is 2.30 GHz with a boost clock of 5.70 GHz. The thermal design power is 65 watts, and it fits the Intel Socket 1700.

Cache allocation on the Intel part is per-core. L1 cache is 80 KB per core, L2 cache is 2 MB per core, and L3 cache is 36 MB shared across all cores. Memory support includes both DDR4 and DDR5, running on a dual-channel bus with 89.6 GB/s of bandwidth. ECC memory is supported. PCI Express connectivity is Gen 5 with 16 lanes from the CPU. Integrated graphics come from the UHD Graphics 730. The processor has a locked multiplier, a launch MSRP of $549, and its production status is active. Its release date is recorded as March 8, 2026, and its part number is SA4QD.

The NVIDIA RTX Spark uses the N1X codename and belongs to the Spark generation labeled GB10. It is manufactured on a 3 nm process at TSMC, with a die size of 208 mm². The processor has 20 cores and 20 threads, with no simultaneous multithreading. Its base clock is 1.70 GHz with a boost clock of 4.00 GHz. The thermal design power is 38 watts, which is lower than the Intel part. No socket is listed, and the market segment is mobile.

Cache on the RTX Spark is also per-core but larger at the L1 level. L1 cache is 128 KB per core, L2 cache is 2 MB per core, and L3 cache is 8 MB shared. Memory support is LPDDR5X only, running on a quad-channel bus with 273.1 GB/s of bandwidth. This is a significantly higher memory bandwidth figure than the Intel part. ECC memory is not supported. PCI Express is listed as N/A. Integrated graphics are provided by the GB20B Blackwell GPU. The multiplier is locked. Production status is unreleased, with a release date of December 31, 2025. No launch MSRP is recorded, and the part number is GSE1-675-A1.

The process node difference is stark: 10 nm for Intel versus 3 nm for the RTX Spark. This gives the RTX Spark a potential efficiency advantage, reflected in its 38 watt TDP compared to 65 watts for the Intel part. The RTX Spark also has more cores (20 versus 12) but fewer threads (20 versus 24) because it lacks multithreading.

Memory architecture differs substantially. The RTX Spark uses quad-channel LPDDR5X with 273.1 GB/s of bandwidth, while the Intel part uses dual-channel DDR4 or DDR5 with 89.6 GB/s. The RTX Spark has over three times the memory bandwidth on paper, which could benefit memory-bound workloads if the processor delivers on its design targets.

Cache hierarchies diverge as well. The RTX Spark has larger L1 per core (128 KB versus 80 KB) and identical L2 per core (2 MB), but much smaller shared L3 (8 MB versus 36 MB). The Intel part compensates with a substantially larger pool of shared cache.

The Intel part supports ECC memory, which the RTX Spark does not. The Intel part also offers PCIe Gen 5 connectivity, while the RTX Spark lists no PCIe support. Market segments differ, with the Intel part aimed at desktop and the RTX Spark aimed at mobile.

The Verdict

The data supports a clear choice for users who need measured performance today. The Intel Core 9 273PE has a complete benchmark profile that places it at the 90th percentile among all CPUs. Its average benchmark score of 49,845 sits within 1.2 percent of its nearest rivals, all of which are established desktop or high-end mobile processors. The 273PE delivers strong multi-core rendering scores, competitive single-thread results, and solid math throughput across integer, floating-point, and extended instruction workloads.

The RTX Spark cannot be evaluated on performance because it has no benchmark scores. The database lists its percentile as 50 and its average score as zero, but these are placeholder values rather than measured outcomes. Its specifications suggest a mobile processor with high memory bandwidth and a modern 3 nm process, but without scores, any performance claim would be speculative.

Users who require a processor with verified rendering performance should choose the Intel Core 9 273PE. The Cinebench R23 multi-core score of 31,288 and single-core score of 4,417 provide concrete reference points. Users who need ECC memory support will also prefer the Intel part, as the RTX Spark lacks this feature.

Users who prioritize memory bandwidth on paper might consider the RTX Spark, which lists 273.1 GB/s against 89.6 GB/s for the Intel part. Users who need lower power consumption might also look at the RTX Spark, with its 38 watt TDP versus 65 watts. However, the lack of benchmark data means these advantages remain theoretical.

Users who need PCIe connectivity should choose the Intel part, as the RTX Spark lists PCIe as N/A. Users who need integrated graphics will find both parts have options: the Intel part uses UHD Graphics 730, while the RTX Spark integrates a GB20B Blackwell GPU.

The data does not support a performance verdict for the RTX Spark. The Intel Core 9 273PE is the only processor in this comparison with recorded scores, and it holds the 90th percentile ranking. Until the RTX Spark receives benchmark measurements, the database treats it as an unreleased mobile processor with no verified capabilities.
