The India-market vivo T4R 5G and vivo Y400 5G differ most in their listed chipsets, display sizes and charging specifications: the T4R has a MediaTek Dimensity 7400 5G and 6.77-inch screen, while the Y400 lists a Snapdragon 4 Gen 2, 6.67-inch screen and higher-capacity battery with faster rated charging. In the official vivo store listings retrieved, comparable T4R variants were listed below the Y400, but Y400 prices varied by listing. Those figures are observations, not guaranteed current checkout prices.

What the specification differences mean
Processor and workload
The T4R lists the MediaTek Dimensity 7400 5G, while the Y400 lists the Snapdragon 4 Gen 2. This gives the T4R the stronger-sounding chipset specification, but the available manufacturer specifications do not establish a real-world speed ranking. They are not a substitute for independent benchmarks or testing in the apps and games you use.

Both list IP68 and IP69 ratings, which should be understood as manufacturer ratings rather than a guarantee against all water damage.
