Architecture and CPU

Switching to two “big” Cortex-A78 cores (instead of Cortex-A76 in earlier Unisoc mid-range chips) plus six efficiency-oriented A55 cores targets steady day-to-day performance with an emphasis on power efficiency. In raw CPU throughput the T8300 sits in the lower half of the mid-range: ample for browsing, messaging, navigation, and most casual games; in heavy workloads (emulators, complex 3D scenes) the two-big-core layout and modest clocks show their limits.

Graphics, display, and multimedia

The Mali-G57 MC2 is a pragmatic pick for FHD panels. Paired with FHD+@120 Hz and HDR Vivid/HDR10+ it delivers comfort in popular titles, though you shouldn’t expect stable 120 fps in demanding games. The video pipeline targets 4K@30 (decode) and 2K@30 (encode)—enough for content consumption and social media, without ambitions for 4K capture.

Unisoc’s game-oriented optimizations at the scheduler/memory/network level reduce FPS drops and loading times. These are engineering tweaks rather than a “magic” boost, but they noticeably improve stability for mass-market devices.

Connectivity and 5G features

Support for 3GPP Release 17 stands out in this class: there are baseline NR NTN (satellite) and 5G MBS (broadcast) capabilities. Also present are Dual-SIM 5G, VoNR/VoWiFi, NR bandwidth up to 100 MHz, and reduced power draw in typical 5G scenarios.

Cameras, imaging, and audio

A quad-core ISP (up to 1.6 Gpixel/s) and Vivimagic Gen7 lift photo/video quality: hardware MFR/TNR, improved 3A 5.0 algorithms, multi-frame night mode, and portrait segmentation. The ceiling is 108 MP for photos; selfies up to 32 MP @ 25 fps; dual-rear 16+16 MP with zero shutter lag. The audio path with a HiFi (HiFi4) codec, 2.0 spatial sound, and extended noise suppression covers multimedia needs.

Memory, storage, and interfaces

The chip targets LPDDR4X and UFS 2.2—a sensible price/UX trade-off. Wireless includes Wi-Fi 5 (optional Wi-Fi 6 1×1), Bluetooth 5.4, major GNSS constellations, and FM radio—sufficient for lower-mid devices.

Comparisons and positioning

Versus Unisoc T820 (previous Unisoc mid-range).
T820 used Cortex-A76 (1+3) and a wider Mali-G57 MP4. T8300 moves to newer Cortex-A78 (2) and a narrower GPU (MC2). In real-world tasks and efficiency the T8300 feels more modern (Rel-17 5G, satellite support, MBS, refreshed audio/ISP), while T820 can show higher theoretical GPU throughput thanks to twice the clusters. Bottom line: T8300 is a step forward in features and efficiency; T820 can be stronger on paper in pure GPU width.

Versus MediaTek Helio G200 (competing 6 nm base mid-range).
Both SoCs use 2× Cortex-A78 + 6× Cortex-A55 and Mali-G57 MC2, so benchmark spread is small. In some tests T8300 posts a slight edge (typically a few percent), but it’s statistical rather than a clear lead. T8300, however, offers broader connectivity (Rel-17 with NTN/MBS), while G200 traditionally leans on HDR photo/video blocks and MediaTek’s software game profiles. Choice depends on device pricing and priorities—connectivity/battery life vs. camera features.

Versus Snapdragon 6 Gen 4 (a tier above).
S6G4 is built on 4 nm and uses newer Cortex-A720/A520 cores and Adreno graphics. It’s predictably stronger in raw performance and efficiency, but also pricier—for both the chip and devices. If you want the latest CPU cores and a beefier GPU, S6G4 wins; if you need a “sensible minimum” for 5G with interesting connectivity features and tight budgets, T8300 is a practical alternative.

In practice and devices

At MWC 2025, the nubia Neo3 5G debuted on the T8300—showing the chip targets not only ultra-budget phones but also affordable “gaming” models with 120 Hz displays. Also used in: nubia Neo 3 5G, HMD Crest 2.

Verdict

The Unisoc T8300 is a “workhorse” of the mass-market 5G segment with a focus on connectivity and multimedia. CPU/GPU performance is solidly mid-range, while standout points include Release-17 features (NTN/MBS), a mature Quad-ISP, and a well-rounded display/audio feature set. Versus the previous Unisoc wave and baseline MediaTek rivals, it looks fresh and competitive—especially in devices where price matters more than maximum FPS.
