Beneath the surface, these two phones tell a surprisingly split story. The Vivo Y29s is powered by the MediaTek Dimensity 6300, while the Redmi Note 14 4G runs the MediaTek Helio G99 — both fabbed on a 6 nm process with near-identical 8-core CPU configurations. In raw CPU throughput, the Y29s actually edges ahead in Geekbench 6, posting 782 single-core and 2012 multi-core versus the Redmi's 729 and 1979 respectively. However, the Redmi pulls significantly ahead in the broader AnTuTu benchmark — 470,000 vs 409,000 — a roughly 15% gap that captures overall system performance including memory, GPU, and I/O, not just CPU cores alone.
The memory picture clarifies that gap. The Redmi ships with 8 GB of RAM running at a notably faster 4266 MHz, compared to the Y29s's 6 GB at 2133 MHz. More RAM means the Redmi handles aggressive multitasking and keeps more apps alive in the background, while the doubled memory speed improves data throughput to the CPU — a combination that explains the AnTuTu lead. One counterpoint: the Y29s supports DirectX 12 versus the Redmi's DirectX 11, which is a theoretical graphics API advantage, though both share an identical GPU clock speed of 950 MHz and near-equivalent GPU silicon.
This category lands as a narrow overall edge to the Redmi Note 14 4G. The Y29s wins on raw CPU benchmarks, but the Redmi's larger, faster RAM pool and higher composite AnTuTu score make it the more capable chip for sustained real-world workloads — gaming sessions, heavy multitasking, and future-proofing. The Y29s is no slouch, but the RAM deficit is a tangible daily-use disadvantage.
