Architecture Differences

The two processors diverge sharply in their architectural layouts. The Intel Core 3 305, codenamed Wildcat Lake, uses 6 cores and 6 threads with no hyperthreading. Its base clock runs at 1.50 GHz with a boost of 4.30 GHz. The chip is built on Intel's 3 nm process at Intel's own foundry. Cache is organized as 192 KB L1, 2.5 MB L2, and 6 MB shared L3. Memory support includes DDR5 and LPDDR5X, but only through a single-channel memory bus, limiting bandwidth to 59.7 GB/s. PCIe connectivity is Gen 4 with 6 lanes from the CPU only. The integrated graphics are Intel Xe3 Graphics with 1 Xe core.

The NVIDIA RTX Spark, codenamed N1X and part of the Spark (GB10) generation, takes a different path. It packs 20 cores and 20 threads, again without hyperthreading. Base clock is 1.70 GHz with a boost of 4.00 GHz. It is manufactured on a 3 nm process at TSMC, and the die size measures 208 mm². Cache structure is per-core: 128 KB L1 per core, 2 MB L2 per core, plus 8 MB shared L3. Memory support is limited to LPDDR5X, but the quad-channel memory bus delivers 273.1 GB/s, more than four times the bandwidth of the Intel part. The chip lists PCIe as N/A. Integrated graphics come from the GB20B "Blackwell" design.

The production status differs: Intel's chip is Active, while the NVIDIA part is unreleased. The Intel chip carries a launch MSRP of $309, while the NVIDIA part has no recorded launch MSRP. Both are mobile market segments and neither supports ECC memory. Neither has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head benchmark list between these two processors is empty. No direct comparative test data exists in the database. The Intel Core 3 305 has a full set of benchmark scores, but the NVIDIA RTX Spark has no recorded benchmarks at all, and its average benchmark score is 0.

The Intel Core 3 305's recorded data shows a wide range of performance. In Cinebench R15, it scores 1,322 multicore and 186 singlecore. In Cinebench R20, the scores are 5,511 multicore and 777 singlecore. Cinebench R23 shows 13,123 multicore and 1,852 singlecore. PassMark results include data compression at 146,857, data encryption at 11,019, extended instructions at 13,543, find prime numbers at 115, floating point math at 42,284, integer math at 32,295, multithread at 15,439, physics at 1,233, random string sorting at 17,623, and single thread at 3,977.

Because the NVIDIA RTX Spark has no scored benchmarks, the database cannot produce a direct comparison. The Intel chip's percentile rank against all CPUs is 72, while the NVIDIA part sits at percentile 50. The Intel chip's average benchmark score of 18,302 places it near the Intel Core i3-14100, Intel Core 5 330, Intel Core 7 360, and AMD Ryzen 5 2600E, all within a 0.4% band.

Without head-to-head results, any performance comparison must rely on architectural specifications. The NVIDIA part's 20 cores versus Intel's 6 cores suggests a multithreaded advantage, but no measured scores confirm it. The Intel part's higher boost clock (4.30 GHz vs 4.00 GHz) suggests a single-thread advantage, but again, no data confirms it.

The Verdict

The data supports a clear split in applicability. The Intel Core 3 305 is an active, measured processor with a full benchmark suite and a 72nd percentile rank. It has a recorded average score of 18,302 and a launch MSRP of $309. Its nearest rivals, the Intel Core i3-14100, Intel Core 5 330, and Intel Core 7 360, all sit within 0.4% of its average score, indicating a tightly competitive field.

The NVIDIA RTX Spark is unreleased, has no benchmarks, and an average score of 0. Its percentile rank of 50 is based on no measured data. The chip's specifications are impressive on paper: 20 cores, 20 threads, a 3 nm TSMC process, a 208 mm² die, and 273.1 GB/s of memory bandwidth. But the database contains no evidence of actual performance.

For a builder selecting a processor today, the Intel Core 3 305 is the only option with verified results. The NVIDIA RTX Spark cannot be evaluated on performance grounds because no scores exist. The Intel chip's 6-core, 6-thread configuration with a 4.30 GHz boost and 6 MB L3 cache delivers measurable results across Cinebench and PassMark tests. Its single-channel memory and 59.7 GB/s bandwidth are limiting factors, but the data shows a functional, active product.

The NVIDIA RTX Spark's 20-core design and quad-channel memory bandwidth point to a different performance envelope, likely favoring heavily threaded workloads. But with no recorded scores, that remains speculative. The database records the Intel chip as Active and the NVIDIA part as unreleased, which reinforces the practical conclusion: choose the Intel Core 3 305 for a working, benchmarked mobile processor, and treat the NVIDIA RTX Spark as an unverified design.

Where Each One Wins

The Intel Core 3 305 wins in every category that requires measured, verified performance. Its benchmark suite covers Cinebench R15, R20, R23, and multiple PassMark tests, all with concrete scores. Its average benchmark score of 18,302 and 72nd percentile rank confirm it as a functional, competitive mobile processor. The chip's 4.30 GHz boost clock is the highest of the two, which supports single-threaded responsiveness. Its 15 TDP is substantially lower than the NVIDIA part's 38, which suggests better efficiency for thermally constrained mobile designs. The Intel chip is also the only one with an Active production status and a recorded launch MSRP of $309.

The NVIDIA RTX Spark wins on raw specifications. Its 20 cores and 20 threads triple the core count of the Intel part. Its 273.1 GB/s memory bandwidth, delivered through a quad-channel bus, is over four times the Intel chip's 59.7 GB/s. The 8 MB shared L3 cache is larger than the Intel's 6 MB. The 208 mm² die size, built on TSMC's 3 nm process, represents a physically larger and potentially more complex design. The integrated GB20B "Blackwell" graphics are a distinct architectural choice compared to Intel's Xe3 Graphics.

For workloads that depend on high memory bandwidth, such as large data movement or memory-intensive compute, the NVIDIA part's specifications point to an advantage. For workloads that depend on measured, available hardware, the Intel part is the only choice. The database records no benchmark wins for either processor in a head-to-head comparison, so the split is based on specification differences and the presence or absence of test data.

The practical builder can rely on the Intel Core 3 305 for immediate deployment with known performance characteristics. The NVIDIA RTX Spark remains a specification sheet without validation, useful only for forward-looking design assumptions until benchmark data appears.
