AMD Instinct MI355X vs AMD Radeon 8050S Comparison

Where Each One Wins

The AMD Instinct MI355X and AMD Radeon 8050S occupy entirely different segments of the GPU landscape, and the recorded data reflects this split clearly. The Instinct MI355X is a compute-oriented accelerator built for data center workloads, while the Radeon 8050S is a mobile integrated graphics processor designed for portable devices. The benchmark database contains no direct head-to-head comparison scores between the two, which is expected given their divergent target applications.

The Radeon 8050S delivers the only recorded benchmark results in this comparison. Its Geekbench OpenCL score of 65,818 and Vulkan score of 58,398 place it in the 89th percentile among all GPUs in the database, with an average benchmark score of 62,108. These measurements indicate that the integrated solution performs competitively against dedicated mobile and desktop GPUs from recent generations. The nearest rival, the AMD Radeon Pro W6600M, scores 61,896, which puts the 8050S just 0.3% ahead. The AMD Radeon Pro Vega 56 trails by 2.5% with a score of 63,693, while the AMD Radeon RX 7600M and AMD Radeon RX 9060 XT LP sit 2.6% and 2.7% behind respectively.

The Instinct MI355X shows no benchmark entries and a percentile ranking of 50, with an average benchmark score of zero. This does not indicate poor performance; rather, it reflects the absence of standardized consumer benchmark data for this accelerator class in the database. The MI355X uses the CDNA 4.0 architecture, which prioritizes throughput and memory capacity over graphics rendering features. Its 78.64 TFLOPS FP32 throughput and 288 GB of HBM3e memory position it for scientific simulation, AI training, and large-scale data processing, where the Radeon 8050S would not be applicable.

The use-case split is therefore straightforward. The Radeon 8050S wins in any workload that requires graphics output, display connectivity, or standard API support, as it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Instinct MI355X offers no display outputs and no graphics API support, making it unsuitable for rendering or gaming. Conversely, the MI355X dominates in compute density, memory bandwidth, and raw FP32 throughput, areas where the 8050S cannot compete.

Architecture Differences

The two GPUs derive from fundamentally different architectural lineages. The Instinct MI355X uses CDNA 4.0, AMD's compute-focused architecture, built on a 3 nm process at TSMC. The Radeon 8050S uses RDNA 3.5, the graphics-oriented architecture, fabricated on a 4 nm process also at TSMC. The process node difference gives the MI355X a density advantage, though the exact transistor count for the 8050S is not recorded in the database.

The die sizes differ dramatically. The MI355X measures 2380 mm² with 185,000 million transistors, yielding a transistor density of 77.7 million per square millimeter. The Radeon 8050S has a die size of 308 mm², and its transistor count is listed as unknown, so no density figure can be calculated. The MI355X integrates 16,384 shading units, 1,024 texture mapping units, and zero ROPs, reflecting its compute-first design. The Radeon 8050S includes 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores, a configuration suited to graphics rendering.

Memory architecture separates the two even further. The MI355X carries 288 GB of HBM3e memory on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The 8050S uses system shared memory, with the size, type, bus width, and bandwidth all dependent on the host system. Clock behavior also diverges: the MI355X runs at a 1000 MHz base and 2400 MHz boost, while the 8050S runs at 1295 MHz base and 2800 MHz boost. The higher clocks on the 8050S reflect its smaller, more thermally manageable design.

Power and physical characteristics reinforce the architectural split. The MI355X has a TDP of 1400 W and requires an 1800 W suggested power supply, mounted as an OAM module. The 8050S operates at 55 W TDP as an IGP, requires no power connectors, and lists no suggested PSU. The MI355X measures 102 mm in length and 165 mm in width, while the 8050S has no recorded dimensions, consistent with its integration into a host processor package.

Head-to-Head Benchmarks

Since the database contains no direct head-to-head benchmark entries for these two products, the comparison relies on the available recorded measurements and architectural specifications. The Radeon 8050S provides the only empirical performance data. Its Geekbench OpenCL score of 65,818 and Vulkan score of 58,398 demonstrate that an integrated GPU can reach the 89th percentile of all GPUs in the database. The average benchmark score of 62,108 places it slightly above the AMD Radeon Pro W6600M at 61,896, a 0.3% margin. Against the AMD Radeon Pro Vega 56 at 63,693, the 8050S trails by 2.5%. The AMD Radeon RX 7600M at 63,775 and the AMD Radeon RX 9060 XT LP at 63,830 sit 2.6% and 2.7% ahead of the 8050S respectively.

The Instinct MI355X has no recorded benchmark scores, so its performance must be inferred from its specifications. The FP32 throughput of 78.64 TFLOPS is approximately 6.9 times the 11.47 TFLOPS of the Radeon 8050S. Texture rate shows a similar disparity: the MI355X delivers 2,457.6 GTexel/s versus 358.4 GTexel/s for the 8050S, a ratio of roughly 6.9. Pixel rate tells a different story, as the MI355X lists 0 MPixel/s due to its lack of ROPs, while the 8050S produces 179.2 GPixel/s. These figures confirm that the MI355X is optimized for compute throughput rather than rasterization.

Memory bandwidth amplifies the compute advantage. The MI355X offers 8.19 TB/s from its HBM3e stack, a figure that the 8050S cannot match because its memory bandwidth is system dependent. The 288 GB capacity on the MI355X dwarfs the shared memory available to the 8050S, which depends entirely on the host system's RAM allocation.
