AMD Radeon 8050S vs AMD Radeon Instinct MI25 Comparison

The AMD Radeon Instinct MI25 and the AMD Radeon 8050S represent two distinct philosophies in GPU design: one is a dedicated, high-power data-center accelerator, while the other is a power-efficient integrated graphics processor for mobile platforms. The data shows a near-tie in raw compute benchmarks, with the MI25 holding a slight edge in the single available comparison, but architectural and physical differences dictate their ideal applications.

Where Each One Wins

The benchmark data reveals a narrow overall victory for the AMD Radeon Instinct MI25, which wins the sole head-to-head comparison. In the Geekbench OpenCL test, the MI25 scores 68562 points, while the Radeon 8050S scores 65818 points, a difference of 4.2%. This makes the MI25 the stronger choice for pure compute throughput in the tested workload. Its 90th percentile ranking among all GPUs, versus the 8050S's 89th percentile, underscores this marginal but consistent advantage in general-purpose compute.

However, the Radeon 8050S claims victory in efficiency and modern feature support. It achieves 89% of the performance of the MI25 while operating within a dramatically lower power envelope. The 8050S has a TDP of 55 W, a fraction of the MI25's 300 W TDP. This makes the 8050S the clear winner for mobile or power-constrained systems where sustained performance per watt is critical. The 8050S also wins on architectural modernity, featuring ray tracing cores and support for DirectX 12 Ultimate, features entirely absent from the older MI25.

The 8050S also shows greater API versatility in the available data, with a Geekbench Vulkan score of 58398. The MI25 has no Vulkan benchmark result in the provided data, suggesting the 8050S is better suited for modern cross-platform workloads that leverage Vulkan. The 8050S's integrated nature (IGP) and lack of power connectors make it the only viable option for thin-and-light laptops, whereas the MI25's dual-slot design and 2x 8-pin power connectors require a full-size desktop or server chassis.

Architecture Differences

The two GPUs are separated by multiple generations of architectural evolution. The Instinct MI25 is built on the Vega 10 chip using the GCN 5.0 architecture, fabricated on a 14 nm process at GlobalFoundries. This older node results in a large 495 mm² die with 12,500 million transistors, yielding a transistor density of 25.3 million per square millimeter. In contrast, the Radeon 8050S uses the Strix Halo chip with the newer RDNA 3.5 architecture, built on a 4 nm TSMC process. This advanced node allows for a smaller 308 mm² die, though exact transistor counts are not disclosed.

The memory subsystems are fundamentally different. The MI25 features a dedicated 16 GB of HBM2 memory on a 2048-bit bus, providing 436.2 GB/s of bandwidth. The 8050S, being an integrated processor, relies on System Shared memory, meaning its bandwidth and capacity are "System Dependent" and not fixed specifications. This gives the MI25 a massive inherent bandwidth advantage for memory-intensive workloads, while the 8050S's performance is tied to the host system's memory configuration.

Core configurations also differ significantly. The MI25 packs 4096 shading units, 256 texture mapping units (TMUs), and 64 raster operation pipelines (ROPs). The 8050S has half the shading units at 2048, but maintains the same 64 ROPs and adds 32 dedicated ray tracing cores. Clock speeds show the 8050S's modern efficiency: it boosts to 2800 MHz versus the MI25's 1500 MHz boost. Pixel and texture rates reflect these differences, with the 8050S achieving 179.2 GPixel/s and 358.4 GTexel/s, versus the MI25's 96.00 GPixel/s and 384.0 GTexel/s. The 8050S also supports newer PCIe 5.0 x16, while the MI25 uses PCIe 3.0 x16.

Head-to-Head Benchmarks

The single direct comparison available is the Geekbench OpenCL test, where the MI25 wins decisively. The MI25 scores 68562, while the 8050S scores 65818. This represents a 4.2% advantage for the MI25. This margin is notable, as it shows the older, dedicated accelerator still holds a performance edge over the newer integrated solution in a pure compute scenario, despite the 8050S's higher clock speeds and newer architecture.

The MI25's nearest rivals in the data provide context for its score. It sits just 0.4% behind the Intel Arc A770 (68809) and 0.6% behind the NVIDIA CMP 90HX (69000). It is ahead of the AMD Radeon Pro WX 8200 by 1.9% (69870) and the NVIDIA Quadro P6000 by 2% (69986). These tight margins indicate that the MI25 is competitive with a range of dedicated desktop and workstation GPUs.

The 8050S's nearest rivals show a different competitive landscape. It leads the AMD Radeon Pro W6600M by 0.3% (61896) and trails the AMD Radeon Pro Vega 56 by 2.5% (63693), the AMD Radeon RX 7600M by 2.6% (63775), and the AMD Radeon RX 9060 XT LP by 2.7% (63830). This positions the 8050S as a mid-tier performer among mobile and low-profile graphics solutions. In the Vulkan test, the 8050S scores 58398, which is lower than its OpenCL score, showing a potential API-specific performance variance.

The Verdict

The data supports a clear split in recommendation based on the target use case. For anyone building or maintaining a rack-mounted server, a workstation with ample power and cooling, or any system where maximum raw compute throughput is the sole priority, the AMD Radeon Instinct MI25 is the better choice. Its 4.2% lead in the Geekbench OpenCL benchmark and its dedicated high-bandwidth HBM2 memory make it superior for heavy data-center tasks. Its 90th percentile ranking and competitive position against cards like the Intel Arc A770 and NVIDIA Quadro P6000 confirm its capability.

For mobile workstations, compact desktops, or any power-sensitive application, the AMD Radeon 8050S is the only sensible option from this pair. Its 55 W TDP, integrated form factor with no power connectors, and support for modern features like ray tracing and DirectX 12 Ultimate make it suitable for portable devices. While it trails the MI25 by 4.2% in compute, its massive efficiency advantage and support for Vulkan 1.4 and PCIe 5.0 make it the forward-looking choice. The 8050S is for users who need good performance in a constrained physical and thermal envelope; the MI25 is for users who need the last drop of performance regardless of power or space costs.
