AMD Instinct MI300A vs Intel Arc Pro B60 Dual Comparison

The Verdict

The AMD Instinct MI300A and Intel Arc Pro B60 Dual occupy entirely separate segments of the GPU market, and the recorded data shows no direct benchmark overlap. The MI300A is a compute-oriented accelerator module with a 50th percentile rank among all GPUs, while the Arc Pro B60 Dual holds the same 50th percentile position but serves a different role as a professional graphics card with display outputs. Neither product has recorded benchmark scores in the database, so comparisons must rely on architectural and specification analysis rather than measured performance.

The MI300A targets high-performance computing workloads that demand massive memory capacity and bandwidth. Its 128 GB of HBM3 memory with 5.32 TB/s bandwidth places it in a class reserved for data center acceleration. The Arc Pro B60 Dual, with 24 GB of GDDR6 memory and 456.0 GB/s bandwidth, suits professional visualization and compute tasks that fit within a more conventional memory envelope. The data indicates the MI300A delivers 61.29 TFLOPS of FP32 throughput against the Arc Pro B60 Dual's 12.29 TFLOPS, a roughly 5x advantage in raw single-precision compute. Conversely, the Arc Pro B60 Dual offers display outputs, 4x mini-DisplayPort 2.1, while the MI300A has no display outputs at all.

The MI300A uses a 5 nm TSMC process with 153,000 million transistors on a 1017 mm² die. The Arc Pro B60 Dual also uses a 5 nm TSMC process but packs 19,600 million transistors on a 272 mm² die. The transistor density figures confirm the MI300A's 150.4M per mm² versus the Arc Pro B60 Dual's 72.1M per mm², indicating the MI300A packs logic more densely. The MI300A draws up to 750 W and requires a 1150 W suggested PSU, while the Arc Pro B60 Dual consumes 400 W with an 800 W suggested PSU. The MI300A is an OAM module with no power connectors listed; the Arc Pro B60 Dual is a dual-slot card using a single 16-pin connector.

Buyers should choose based on workload requirements. The MI300A is the only option for applications needing 128 GB of HBM3 memory or 5.32 TB/s of bandwidth. The Arc Pro B60 Dual is the only option for systems requiring PCIe 5.0 x8 connectivity, DirectX 12 Ultimate support, or multiple display outputs. The Arc Pro B60 Dual also has a launch MSRP of 1,199 USD. The MI300A launched on 2023-12-05, and the Arc Pro B60 Dual followed on 2025-09-04.

Architecture Differences

The MI300A uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, part of the Instinct (MIx) generation. The Arc Pro B60 Dual uses the Xe2-HPG architecture on the BMG-G21 chip, belonging to the Battlemage (Pro Series) generation. Both are fabricated on a 5 nm process at TSMC, but their design philosophies diverge sharply.

The MI300A integrates 14,592 shading units, 912 texture mapping units, and no ROPs, reflecting its compute-first design with a 0 MPixel/s pixel rate. The Arc Pro B60 Dual includes 2,560 shading units, 160 TMUs, 80 ROPs, and 20 ray tracing cores, producing a 192.0 GPixel/s pixel rate. The MI300A has no ray tracing cores listed, while the Arc Pro B60 Dual includes dedicated RT hardware. Neither product lists tensor cores in the database.

Memory architecture differs fundamentally. The MI300A uses HBM3 with an 8192-bit bus, delivering 5.32 TB/s bandwidth at 1300 MHz (5.2 Gbps effective). The Arc Pro B60 Dual uses GDDR6 on a 192-bit bus, achieving 456.0 GB/s at 2375 MHz (19 Gbps effective). Clock speeds also diverge: the MI300A runs at 1000 MHz base and 2100 MHz boost, while the Arc Pro B60 Dual operates at 2000 MHz base and 2400 MHz boost. The higher clocks on the Arc Pro B60 Dual partially compensate for its smaller compute array.

API support separates the two. The MI300A reports N/A for DirectX, OpenGL, and Vulkan, indicating it is not intended for graphics APIs. The Arc Pro B60 Dual supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300A uses a PCIe 5.0 x16 interface; the Arc Pro B60 Dual uses PCIe 5.0 x8. The Arc Pro B60 Dual is the only one with a production status of Active, while the MI300A's status is not recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the MI300A and Arc Pro B60 Dual, and neither product has recorded benchmark scores or nearest rivals. The wins count stands at 0 for both products. However, the specification data enables a meaningful comparison of expected performance in different workload categories.

The MI300A dominates in memory-bound compute. Its 5.32 TB/s bandwidth exceeds the Arc Pro B60 Dual's 456.0 GB/s by a factor of 11.7x. For large language model inference or scientific simulation datasets that exceed 24 GB, the MI300A's 128 GB capacity is the decisive advantage. The Arc Pro B60 Dual cannot load models or datasets that require more than 24 GB of memory, whereas the MI300A can hold over 5x that amount.

In raw compute throughput, the MI300A's 61.29 TFLOPS FP32 is 4.99x the Arc Pro B60 Dual's 12.29 TFLOPS. Texture rate follows a similar pattern: 1,915.2 GTexel/s versus 384.0 GTexel/s, a 4.99x difference. The MI300A's 912 TMUs versus 160 TMUs explains this gap. For pixel processing, the Arc Pro B60 Dual's 80 ROPs deliver 192.0 GPixel/s, while the MI300A has 0 ROPs and a 0 MPixel/s pixel rate, meaning it cannot perform traditional rasterization. The Arc Pro B60 Dual also provides FP16 compute at 24.58 TFLOPS with 2:1 ratio, a feature not listed for the MI300A.

Clock speeds favor the Arc Pro B60 Dual: 2000 MHz base and 2400 MHz boost versus 1000 MHz base and 2100 MHz boost. The Arc Pro B60 Dual's base clock is 2x higher, and its boost clock is 14% higher. This suggests the Arc Pro B60 Dual can execute single-threaded or latency-sensitive workloads more quickly per instruction, though the MI300A's massive parallel array overwhelms this advantage in throughput-oriented tasks.

Memory technology differences shape power and packaging. The MI300A's HBM3 on an 8192-bit bus requires an OAM module form factor and consumes 750 W. The Arc Pro B60 Dual's GDDR6 on a 192-bit bus fits a dual-slot card at 400 W. The MI300A's 153,000 million transistors on a 1017 mm² die compare to 19,600 million on 272 mm² for the Arc Pro B60 Dual. The MI300A uses 7.8x more transistors and occupies 3.7x more die area, but its transistor density of 150.4M per mm² is 2.1x higher than the Arc Pro B60 Dual's 72.1M per mm².

For gaming or general graphics workloads, the Arc Pro B60 Dual is the only contender because it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300A lists N/A for all graphics APIs. The Arc Pro B60 Dual's 20 ray tracing cores add hardware acceleration for ray-traced rendering, a capability absent from the MI300A. The Arc Pro B60 Dual's 4x mini-DisplayPort 2.1 outputs enable multi-monitor professional visualization, which the MI300A cannot provide.

The release timeline shows the MI300A debuted on 2023-12-05, and the Arc Pro B60 Dual arrived on 2025-09-04, a 21-month gap. The Arc Pro B60 Dual is marked Active in production, while the MI300A's production status is not recorded. The database lists the predecessor for the MI300A as Radeon Instinct, while the Arc Pro B60 Dual has no recorded predecessor.
