AMD Instinct MI308X vs AMD Radeon RX 9050 OEM Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the AMD Instinct MI308X and the AMD Radeon RX 9050 OEM. Neither product has any stored benchmark scores, and the wins tally is zero for both. This makes a purely numerical comparison of measured performance impossible from the available data. What can be compared is the theoretical peak throughput derived from the specification sheets. The MI308X delivers 81.72 TFLOPS of FP32 compute, while the RX 9050 OEM delivers 10.65 TFLOPS. That places the MI308X at roughly 7.7 times the raw FP32 throughput of the RX 9050 OEM, a substantial margin that reflects their entirely different design goals. The MI308X also shows a texture rate of 2,553.6 GTexel/s against 166.4 GTexel/s for the RX 9050 OEM, a 15.3 times difference. In pixel throughput, the RX 9050 OEM has a recorded 166.4 GPixel/s, while the MI308X is listed at 0 MPixel/s, meaning it has no raster output pipeline for conventional display rendering.

Architecture Differences

The two accelerators come from different architectural lineages. The MI308X uses the CDNA 3.0 architecture with the Aqua Vanjaram chip, built on a 5 nm process at TSMC. The RX 9050 OEM uses RDNA 4.0 with the Navi 44 chip, built on a 4 nm process, also at TSMC. The MI308X integrates 153,000 million transistors across a 1017 mm² die, resulting in a transistor density of 150.4M per mm². The RX 9050 OEM integrates 29,700 million transistors on a 199 mm² die, with a density of 149.2M per mm². The densities are nearly identical, but the MI308X die is over five times larger.

The MI308X has 19,456 shading units and 1,216 texture mapping units, with no ROPs recorded. The RX 9050 OEM has 1,024 shading units, 64 TMUs, and 64 ROPs. The RX 9050 OEM includes 16 ray tracing cores, while the MI308X has none listed. Neither part lists tensor cores in the database. The MI308X uses HBM3 memory totaling 192 GB across an 8192 bit bus, yielding 5.32 TB/s of bandwidth. The RX 9050 OEM uses 4 GB of GDDR6 on a 64 bit bus, yielding 144.0 GB/s. Clock behavior also differs: the MI308X runs at a 1000 MHz base and 2100 MHz boost, with memory at 1300 MHz (5.2 Gbps effective). The RX 9050 OEM runs at 1330 MHz base, 1920 MHz game clock, and 2600 MHz boost, with memory at 2250 MHz (18 Gbps effective).

The MI308X is a compute accelerator with no display outputs. The RX 9050 OEM is a graphics card with 1x HDMI 2.1b and 2x DisplayPort 2.1a outputs. The MI308X supports no DirectX, OpenGL, or Vulkan APIs in the database, while the RX 9050 OEM supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI308X is an OAM module with no power connectors, while the RX 9050 OEM is a dual-slot card with one 8-pin connector. The MI308X has a 750 W TDP and requires a suggested 1150 W PSU. The RX 9050 OEM has a 92 W TDP and a suggested 250 W PSU.

Where Each One Wins

The MI308X wins decisively in compute-heavy workloads. Its FP32 throughput of 81.72 TFLOPS is 7.7 times that of the RX 9050 OEM. Its texture rate of 2,553.6 GTexel/s is 15.3 times higher. Its memory bandwidth of 5.32 TB/s is 36.9 times greater than the 144.0 GB/s of the RX 9050 OEM, and its 192 GB of HBM3 vastly exceeds 4 GB of GDDR6. The MI308X also has nearly 19 times more shading units and 19 times more TMUs. This makes it suited for large-scale data processing, AI inference, and scientific simulation workloads where memory capacity and bandwidth are critical.

The RX 9050 OEM wins in conventional graphics rendering. It has 64 ROPs and a pixel rate of 166.4 GPixel/s, while the MI308X has none. It includes 16 ray tracing cores, which the MI308X lacks. It supports modern graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI308X supports none of these. The RX 9050 OEM has display outputs for connecting monitors, whereas the MI308X has no outputs. Its game clock of 1920 MHz and boost of 2600 MHz are higher than the MI308X boost of 2100 MHz. The RX 9050 OEM also has a much lower power envelope at 92 W versus 750 W, and its PCB footprint is a standard dual-slot card rather than an OAM module.

The Verdict

The data indicates two products with no overlap in purpose. The AMD Instinct MI308X is a compute accelerator built for bandwidth and throughput. Its 192 GB of HBM3 memory, 5.32 TB/s bandwidth, and 81.72 TFLOPS of FP32 compute place it in a category for large-scale parallel workloads. It has no display pipeline, no graphics API support, and consumes 750 W. The AMD Radeon RX 9050 OEM is a graphics card with a full rendering pipeline, including 64 ROPs, 16 ray tracing cores, and modern API support. Its 10.65 TFLOPS and 144.0 GB/s bandwidth are modest by comparison, but its 92 W TDP and standard dual-slot form factor make it a conventional consumer-style product.

For users needing maximum compute throughput and memory capacity, the MI308X is the only choice between the two. Its texture rate of 2,553.6 GTexel/s and FP32 output are multiple times higher than the RX 9050 OEM. For users needing a graphics card with display outputs, ray tracing, and DirectX 12 Ultimate support, the RX 9050 OEM is the only viable option, as the MI308X cannot output video or run graphics APIs. The release dates confirm this split: the MI308X launched in December 2023, while the RX 9050 OEM is dated July 2026 and listed as active production. The benchmark database currently holds no measured scores for either product, so these conclusions rest on the recorded specifications rather than workload testing.
