GPU & Compute Power
| Chipset | Compute Score |
|---|---|
| Dimensity 8400 | 12,817 |
| Exynos 1580 | 6,934 |
The Mali-G720 MP7 GPU in the Dimensity 8400 offers vastly better graphics performance than the Exynos 1580’s Xclipse 540 GPU. Despite Samsung leveraging AMD’s RDNA3 architecture, it doesn’t translate into real-world superiority, especially in gaming.
Architecture and Memory Differences
| Feature | Dimensity 8400 | Exynos 1580 |
|---|---|---|
| Big Core | 1x Cortex-A725 @ 3.25GHz | 1x Cortex-A720 @ 2.9GHz |
| Cluster Configuration | 1+3+4 (A725+A725+A520) | 1+3+4 (A720+A720+A520) |
| Instruction Set | ARMv9.2-A | ARMv9-A |
| GPU | Mali-G720 MP7 @ 1300 MHz | Xclipse 540 (AMD RDNA3) |
| RAM | LPDDR5X @ 4266 MHz | LPDDR5 @ 3200 MHz |
| Storage | UFS 4.0 | UFS 3.1 |
| Cache | 6MB L3 Cache | 6MB L3 Cache |
Dimensity 8400 uses faster RAM, storage, and cores with a more modern instruction set. These improvements add up, especially in multitasking and read/write performance.
Connectivity and Multimedia Support
| Feature | Dimensity 8400 | Exynos 1580 |
|---|---|---|
| 5G Download Speeds | Up to 5170 Mbps | Up to 5100 Mbps |
| Wi-Fi | Wi-Fi 6 | Wi-Fi 6 |
| Bluetooth | 6.0 | 5.3 |
| Camera Support | Up to 320MP | Up to 200MP |
| AV1 Decode | Yes | No |
| Memory Bandwidth | 68.2 Gbit/s | 51.2 Gbit/s |
The Dimensity 8400 not only supports higher camera resolutions and AV1 decoding but also offers slightly faster 5G and superior memory bandwidth, all translating into smoother media streaming and data-intensive performance.
Verdict—Dimensity 8400 Is the Undeniable Winner
Taking a comprehensive look at both chipsets, it’s clear that the Dimensity 8400 offers a significantly better package across all metrics. From benchmark scores and gaming performance to memory speed, camera capabilities, and AI processing, MediaTek’s chipsets set a new bar for what a mid-range processor can deliver in 2025. It brings flagship-level experiences to devices like the vivo Y300 GT, positioning itself as a true disruptor in the market.
The Exynos 1580, while not a poor performer by any means, simply doesn’t measure up in the same league. It caters more to average users who prioritize brand loyalty, daily usability, and Samsung’s software ecosystem. However, for those seeking maximum performance, longer hardware relevance, and better multimedia capabilities, the Dimensity 8400 is the clear winner.
In conclusion, MediaTek has proven once again that it is a serious contender not just in the budget segment but also in premium mid-range smartphones. The vivo Y300 GT, powered by Dimensity 8400, is a smarter investment for users looking for top-tier features without paying flagship prices.
