Where Each One Wins

The Core Ultra X9 388H wins decisively in every workload category represented in the benchmark suite. Its largest advantages are in tasks that scale with core count and memory bandwidth. The data shows the X9 388H is 68.2% ahead in prime number finding, 63.4% ahead in integer math, and 61% ahead in floating point math. These results align with its 16 cores versus 6 cores and its dual-channel memory bus. Data compression and encryption, which rely on both parallel processing and memory throughput, also strongly favor the X9 388H, with deltas of -59.8% and -61.1% respectively.

The Core 5 330, while losing every benchmark, shows its most competitive result in PassMark single thread, where it trails by only 4.5%. This suggests that for lightly threaded, short-duration tasks, the Core 5 330 can operate near the level of the X9 388H. Its Cinebench R23 singlecore score of 1856 is also respectable, though the X9 388H still leads by 15.7%. The Core 5 330's 6-thread configuration and lower 15 W TDP make it a more power-conscious choice for basic productivity, where the performance gap to the X9 388H in single-core tasks is less pronounced.

For multi-threaded rendering, the X9 388H is the clear choice. Cinebench R23 multicore shows a 30.5% gap, and R20 multicore shows a 57.8% gap. The X9 388H's 18 MB of shared L3 cache, compared to 6 MB on the Core 5 330, also contributes to its superior performance in cache-sensitive workloads like data compression. The X9 388H's memory bandwidth of 153.6 GB/s, versus 59.7 GB/s for the Core 5 330, further explains its dominance in memory-intensive PassMark tests.
