Under the hood, these two phones take very different silicon paths to the same destination — both are fabricated on a 3 nm process with 16 GB of DDR5 RAM and 1 TB of storage — yet the benchmark numbers tell a clear story. The Vivo X300 Pro, powered by the MediaTek Dimensity 9500, outscores the X200 Ultra's Qualcomm Snapdragon 8 Elite across every measured metric: its AnTuTu score of 3,015,900 beats the X200 Ultra's 2,819,127 by roughly 7%, and the gap widens in Geekbench 6, where the X300 Pro posts 3,781 single-core and 12,189 multi-core versus the X200 Ultra's 3,234 and 10,059 respectively. That multi-core lead of over 21% is particularly significant for sustained workloads like video rendering, large file processing, and multitasking under load.
Two architectural details further separate them. The X300 Pro carries a 16 MB L3 cache — double the X200 Ultra's 8 MB — which reduces latency on repeated data access and helps sustain peak CPU performance in complex tasks. The GPU clock speeds also diverge sharply: the X300 Pro's Mali G1 Ultra MP12 runs at 1750 MHz versus the Adreno 830's 1100 MHz, though GPU architectures differ enough between Qualcomm and MediaTek that clock speed alone does not straightforwardly translate to proportional graphics performance. Memory bandwidth is virtually identical at around 85 GB/s on both.
On raw, measured performance, the X300 Pro holds a clear advantage. Its benchmark leads are consistent and meaningful, not marginal — users who push their device hard through gaming, AI tasks, or heavy multitasking will find the Dimensity 9500 measurably ahead of the Snapdragon 8 Elite in this data set.
