At a headline level, these two devices are remarkably close in performance. The AnTuTu scores are essentially identical — 684,046 for the Realme P3 versus 685,000 for the Vivo T4x 5G — a gap so small it is indistinguishable in real-world use. Both are built on a 4 nm process node, share the same DDR5 memory standard, and top out at 16 GB of maximum RAM, so the generational foundation is on equal footing.
Dig deeper, however, and a split picture emerges. The Realme P3's Snapdragon 6 Gen 4 with its Adreno 810 GPU pulls ahead in CPU-focused tasks, posting higher Geekbench 6 scores in both single-core (1,104 vs 1,031) and multi-core (3,105 vs 2,827) tests — an advantage that translates to snappier app launches and smoother sustained workloads. The Vivo T4x's Dimensity 7300, meanwhile, counters with a notably higher GPU clock speed (1,047 MHz vs 800 MHz) and a significantly faster RAM bus at 6,400 MHz versus 2,750 MHz, which can benefit memory-intensive operations and data throughput.
Taken together, this is one of the closest performance matchups these specs can produce. That said, the Realme P3's measurable CPU benchmark lead is consistent across both single and multi-core workloads, and for the tasks most users care about daily — app responsiveness, multitasking, gaming — CPU throughput tends to be the dominant factor. The Realme P3 earns a narrow edge here, though users who prioritize GPU-heavy workloads may find the T4x's higher GPU clock worth noting.
