AMD Instinct MI308X vs AMD Radeon AI PRO 9600D Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the AMD Instinct MI308X versus the AMD Radeon AI PRO 9600D. Both entries show an average benchmark score of zero, and their percentile rankings among all GPUs are identical at 50. The wins counter for each product is zero, indicating that no direct comparative measurements have been logged that would separate the two in compute workloads, rendering, or AI inference tasks.

The absence of benchmark data does not erase the measurable differences between the two accelerators. The Instinct MI308X delivers 81.72 TFLOPS of FP32 throughput, while the Radeon AI PRO 9600D delivers 24.82 TFLOPS. That places the MI308X at roughly 3.3 times the raw FP32 compute of the Radeon AI PRO 9600D. For FP16 workloads, both cards operate at a 1:1 ratio with their FP32 rates, so the same multiplier holds: the MI308X reaches 81.72 TFLOPS FP16, and the Radeon AI PRO 9600D reaches 24.82 TFLOPS FP16.

Texture throughput follows the same pattern. The MI308X sustains 2,553.6 GTexel/s against 387.8 GTexel/s for the Radeon AI PRO 9600D, a difference of approximately 6.6 times. Pixel rate tells a more complex story. The MI308X reports 0 MPixel/s, which prevents any direct pixel processing comparison, while the Radeon AI PRO 9600D manages 193.9 GPixel/s. The MI308X is not designed for traditional rasterization output, as evidenced by its zero ROP count, whereas the Radeon AI PRO 9600D carries 96 ROPs.

Memory bandwidth separates the two by an even wider margin. The Instinct MI308X uses 192 GB of HBM3 across an 8192-bit bus, yielding 5.32 TB/s. The Radeon AI PRO 9600D uses 32 GB of GDDR6 across a 256-bit bus, yielding 576.0 GB/s. That is a 9.2 times bandwidth advantage for the MI308X, along with a 6 times capacity advantage. The memory clock rates reflect the different technologies: the MI308X runs memory at 1300 MHz (5.2 Gbps effective), while the Radeon AI PRO 9600D runs at 2250 MHz (18 Gbps effective). The higher effective data rate on the GDDR6 part does not offset the much wider HBM3 bus.

Clock speeds on the compute side are closer. The MI308X has a base clock of 1000 MHz and a boost clock of 2100 MHz. The Radeon AI PRO 9600D has a base clock of 1080 MHz, a game clock of 1080 MHz, and a boost clock of 2020 MHz. The MI308X boosts slightly higher, but the Radeon AI PRO 9600D holds a higher base clock. The compute gap is therefore driven by the sheer difference in shading units: 19,456 on the MI308X versus 3,072 on the Radeon AI PRO 9600D.

Architecture Differences

The two accelerators come from different architectural families. The Instinct MI308X is built on CDNA 3.0, while the Radeon AI PRO 9600D is built on RDNA 4.0. The CDNA line is compute-oriented, and the RDNA line is graphics-oriented. This distinction appears in the feature sets. The MI308X has no display outputs, no ROPs, and no supported graphics APIs. The Radeon AI PRO 9600D has one DisplayPort 2.1a output, 96 ROPs, and full API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The chip designs reinforce the split. The MI308X uses the Aqua Vanjaram chip, a large 1017 mm² die fabricated on a 5 nm process at TSMC. The Radeon AI PRO 9600D uses the Navi 48 chip, a 357 mm² die fabricated on a 4 nm process at TSMC. Transistor counts differ greatly: the MI308X packs 153,000 million transistors, while the Radeon AI PRO 9600D packs 53,900 million. Transistor density is nearly identical despite the node difference, at 150.4M per mm² for the MI308X and 151.0M per mm² for the Radeon AI PRO 9600D.

Shading unit counts separate the two architectures clearly. The MI308X has 19,456 shading units and 1,216 texture mapping units. The Radeon AI PRO 9600D has 3,072 shading units and 192 texture mapping units. The MI308X has no ROPs, while the Radeon AI PRO 9600D has 96. The Radeon AI PRO 9600D also includes 48 ray tracing cores, a feature absent from the MI308X listing.

Memory architecture reflects the differing purposes. The MI308X uses HBM3 with a 8192-bit bus width, which enables its 5.32 TB/s bandwidth. The Radeon AI PRO 9600D uses GDDR6 with a 256-bit bus, which caps bandwidth at 576.0 GB/s. The MI308X is a compute accelerator designed for memory-heavy workloads, while the Radeon AI PRO 9600D targets workstation graphics with conventional GDDR6 memory.

Both cards use PCIe 5.0 x16 as their bus interface. Power delivery differs substantially. The MI308X has no power connectors because it is an OAM module, and it lists a 750 W TDP with a 1150 W suggested PSU. The Radeon AI PRO 9600D uses a single 16-pin power connector, has a 150 W TDP, and lists a 450 W suggested PSU.

The release dates place the two in different generations. The Instinct MI308X launched on 2023-12-05 and belongs to the Instinct (MIx) generation, with the Radeon Instinct as its predecessor. The Radeon AI PRO 9600D launched on 2025-12-10, belongs to the Radeon Pro Navi (Navi IV Series) generation, and lists the Radeon Pro Vega as its predecessor. The Radeon AI PRO 9600D is marked as Active in production status, while the MI308X has no production status recorded.

Where Each One Wins

The Instinct MI308X wins in every compute-oriented metric recorded in the database. Its FP32 and FP16 throughput of 81.72 TFLOPS exceeds the Radeon AI PRO 9600D's 24.82 TFLOPS. Its texture rate of 2,553.6 GTexel/s is roughly 6.6 times the 387.8 GTexel/s of the Radeon AI PRO 9600D. Its memory bandwidth of 5.32 TB/s is 9.2 times the 576.0 GB/s of the smaller card. Its 192 GB of HBM3 memory provides six times the capacity of the 32 GB GDDR6 pool on the Radeon AI PRO 9600D. The MI308X also carries far more shading units (19,456 versus 3,072) and TMUs (1,216 versus 192), which explains its large lead in shader and texture work.

The Radeon AI PRO 9600D wins in every graphics-oriented metric. It has 96 ROPs and a pixel rate of 193.9 GPixel/s, while the MI308X has zero ROPs and a 0 MPixel/s pixel rate. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI308X reports no graphics API support. It includes 48 ray tracing cores, a feature entirely absent from the MI308X record. It has a display output, one DisplayPort 2.1a, while the MI308X has no outputs. It also has a higher base clock (1080 MHz versus 1000 MHz) and a higher memory data rate (18 Gbps effective versus 5.2 Gbps effective), though the latter is offset by the much narrower bus.

Power efficiency is another clear win for the Radeon AI PRO 9600D. Its TDP of 150 W is one fifth of the MI308X's 750 W, and its suggested PSU of 450 W is far lower than the 1150 W suggested for the MI308X. The Radeon AI PRO 9600D also fits in a single slot with a 241 mm length, while the MI308X is an OAM module without recorded dimensions.

The use-case split is sharp. The MI308X is a server-class compute accelerator for large-scale FP32 or FP16 workloads, with massive memory capacity and bandwidth to support data-intensive processing. The Radeon AI PRO 9600D is a workstation graphics card with ray tracing, rasterization, and display output, suited for tasks that require DirectX, OpenGL, or Vulkan support. Neither card replaces the other. The data shows two products optimized for different ends of the AMD accelerator lineup.
