The MT6515A/B chipset is designed for entry-level smartphones that prioritize affordability over high-end performance. It is built around a single-core ARM Cortex-A5 processor, which runs at a maximum frequency of 1.0 GHz. This processor is efficient for basic tasks such as voice calls, text messaging, web browsing, and using lightweight apps. However, it may not perform well with resource-intensive applications like HD gaming or complex multitasking. The Cortex-A5 architecture is a lower-end design compared to newer cores like the Cortex-A7 or A9 but still provides a sufficient experience for entry-level devices.

For graphics, the MT6515A/B integrates the Mali-400 MP GPU, a budget-friendly graphics processor that is adequate for HD video playback and light gaming. The GPU can support video playback in standard HD resolutions and run less demanding games, but users will not be able to play the latest 3D games or stream high-definition video smoothly on this chipset. It supports displays up to WVGA (800x480), which offers reasonable image clarity for basic smartphone use. Although this resolution is not as sharp as higher-end displays, it is acceptable for browsing, watching videos, and using basic apps.

For camera functionality, the MT6515A/B can support up to a 5 MP rear camera. The camera is capable of recording 720p HD videos, providing users with decent photo and video quality for everyday use, such as social media sharing or personal snapshots. While the quality may not be as high as more expensive smartphones, it is still suitable for casual photography.

In terms of connectivity, the MT6515A/B supports 3G HSPA with speeds up to 14.4 Mbps, which is sufficient for general web browsing, social media use, and light data tasks like checking emails or streaming music. While the speed is lower than 4G LTE, it is adequate for the needs of users with basic internet usage requirements. Additionally, the chipset supports Wi-Fi 802.11 b/g/n for connecting to wireless networks and Bluetooth 3.0 for transferring files or connecting wireless accessories such as headphones. GPS with A-GPS allows the device to use location-based services, such as navigation apps, although its performance might not be as fast or accurate as newer systems.

A key feature of the MT6515A/B is its dual-SIM support, which is popular in many markets for users who wish to manage two phone numbers on one device, either for personal and business use or for taking advantage of different carrier plans. The dual SIM (dual standby) functionality makes it easier for users to maintain multiple networks without needing separate devices.

To improve battery performance, the MT6515A/B integrates MediaTek’s power-saving technology, allowing smartphones using this chipset to last longer on a single charge despite being equipped with smaller batteries, which is common for entry-level devices.
