Intel Core 5 320 vs Intel Core Ultra 5 235A Comparison

Intel Core 5 320 and Intel Core Ultra 5 235A are both active Intel parts, but they serve entirely different segments of the market. The Core 5 320 is a 6-core mobile processor built on the Wildcat Lake architecture, while the Core Ultra 5 235A is a 14-core desktop processor from the Arrow Lake family. The benchmark data shows a complete and decisive performance gap between the two, with the Core Ultra 5 235A winning all 17 head-to-head comparisons. This analysis will break down the exact margins, the architectural reasons behind them, and which workloads favor which processor.

Head-to-Head Benchmarks

The most striking result is in multi-threaded rendering. In Cinebench R23 multicore, the Core Ultra 5 235A scores 32633, which is 81% ahead of the Core 5 320's 6197. This is the largest single delta in the entire benchmark suite. The gap narrows in Cinebench R15 multicore, where the Core Ultra 5 235A's 3289 still beats the Core 5 320's 1054 by 68%. Similarly, in Cinebench R20 multicore, the 13705 score from the Core Ultra 5 235A represents a 60.1% advantage over the 5462 from the Core 5 320.

Single-threaded performance is also firmly in the Core Ultra 5 235A's favor, though the margins are smaller. In Cinebench R23 singlecore, the Core Ultra 5 235A scores 4607, which is 58.2% higher than the Core 5 320's 1926. The Cinebench R20 singlecore test shows a 60.1% lead for the Core Ultra 5 235A (1934 vs 771). In Cinebench R15 singlecore, the lead is 40.5% (464 vs 276). The smallest single-thread gap appears in Passmark single thread, where the Core Ultra 5 235A's 4557 is only 11.2% ahead of the Core 5 320's 4045. This indicates that the Core 5 320 has competitive per-core efficiency, but the Core Ultra 5 235A still wins outright.

The Passmark suite shows consistent dominance across all workloads. Data compression is 62.2% better on the Core Ultra 5 235A (393800 vs 148779). Data encryption shows a 63.6% lead (30136 vs 10984). Extended instructions are 58.1% faster (31625 vs 13262). Prime number finding shows a 71.9% advantage (392 vs 110). Floating point math is 64.3% faster (118778 vs 42440). Integer math is 63.5% faster (88626 vs 32323). Random string sorting is 63.6% faster (49489 vs 18038). The multithread score is 59.8% higher (38392 vs 15450). Physics is 49.9% better (2437 vs 1221).

The average benchmark score confirms the overall picture. The Core Ultra 5 235A has an average score of 48201, placing it in the 90th percentile of all CPUs. The Core 5 320 has an average score of 18023, which is in the 72nd percentile. The Core Ultra 5 235A's nearest rivals include the AMD Ryzen AI Max PRO 380 (0.1% delta), Intel Core Ultra 5 245HX (-0.2% delta), and AMD Ryzen 9 3900 (0.6% delta). The Core 5 320's nearest rivals are the AMD Ryzen 5 1600 (0.2% delta), Intel Core 5 120U (0.7% delta), and AMD Ryzen 5 3600XT (0.7% delta). These rival positions show that the Core Ultra 5 235A competes in a much higher performance class.

Where Each One Wins

The Core Ultra 5 235A wins every single benchmark in the database, so there is no workload category where the Core 5 320 comes out ahead. However, the relative margins vary, which points to different strengths. The Core Ultra 5 235A's largest advantage is in multi-threaded rendering. The Cinebench R23 multicore delta of 81% is the biggest win, followed by prime number finding at 71.9% and Cinebench R15 multicore at 68%. These results indicate that the Core Ultra 5 235A is vastly superior for heavily threaded workloads such as video rendering, scientific simulations, and 3D scene generation.

The Core Ultra 5 235A shows its smallest advantage in single-threaded Passmark tests. The 11.2% lead in Passmark single thread is the closest result. This suggests that the Core 5 320's architecture is relatively efficient on a per-thread basis, even though it cannot match the raw performance of the Core Ultra 5 235A. The Core Ultra 5 235A still holds a 40.5% lead in Cinebench R15 singlecore, so the gap is consistent but smaller in less demanding single-thread tasks.

For data-centric workloads, the Core Ultra 5 235A delivers strong but not extreme advantages. Data compression is 62.2% faster, data encryption is 63.6% faster, and random string sorting is 63.6% faster. These are significant margins, but they are not as large as the rendering deltas. The Core Ultra 5 235A also leads by 58.1% in extended instructions and 63.5% in integer math, showing strong general compute capabilities.

The Core 5 320, despite losing all benchmarks, has a specific use case profile. Its 6 cores, 6 threads, and 15W TDP indicate a low-power mobile processor. Its single-thread Passmark score of 4045 is respectable and close to the Core Ultra 5 235A's 4557. In applications that are lightly threaded and sensitive to power consumption, the Core 5 320 would be more appropriate, but the data shows that in any performance comparison, the Core Ultra 5 235A is the clear winner.

The Verdict

The data is unambiguous: the Intel Core Ultra 5 235A is the superior processor in every measured benchmark. It wins all 17 head-to-head tests, with an average score of 48201 compared to the Core 5 320's 18023. The Core Ultra 5 235A sits in the 90th percentile of all CPUs, while the Core 5 320 is in the 72nd percentile. For anyone building a desktop system requiring high multi-threaded performance, the Core Ultra 5 235A is the only choice from these two.

The Core 5 320 should be considered only for its intended mobile segment. As a 6-core, 6-thread processor with a 15W TDP, it is designed for power-constrained laptops. Its 72nd percentile rank means it is not a weak processor, but it is outclassed by the Core Ultra 5 235A in every category. The 81% deficit in Cinebench R23 multicore makes it unsuitable for any demanding desktop workload.

Pick the Core Ultra 5 235A for desktop builds, heavy rendering, data processing, or any task where performance is the priority. Pick the Core 5 320 for a mobile device where low power consumption and adequate single-thread performance are more important than raw throughput. The Core Ultra 5 235A's launch MSRP is $269, and the Core 5 320's launch MSRP is $340, but the performance gap vastly exceeds the price difference.
