Intel’s card runs at substantially higher frequencies, though the AMD part’s memory clock is 1300 MHz (5.2 Gbps effective) versus Intel’s 2375 MHz (19 Gbps effective).

Q: What are the display output capabilities of each card?

A: The AMD Instinct MI300 has no display outputs, making it a compute-only accelerator. The Intel Arc Pro B60 Dual includes 4x mini-DisplayPort 2.1 outputs, enabling direct display connectivity. This is a fundamental difference in their intended use cases.

Q: What is the power connector and PSU requirement for each?

A: The AMD Instinct MI300 uses 2x 8-pin power connectors and requires a 1000 W suggested PSU. The Intel Arc Pro B60 Dual uses a single 16-pin connector with an 800 W suggested PSU. The AMD card’s TDP is 600 W, while Intel’s is 400 W.

Where Each One Wins

The AMD Instinct MI300 wins decisively in raw compute throughput and memory capacity. Its FP32 performance is 47.87 TFLOPS, compared to Intel’s 12.29 TFLOPS, a 3.9x advantage. The texture rate is 1,496.0 GTexel/s versus 384.0 GTexel/s, a 3.9x lead. The AMD card’s 128 GB HBM3 memory dwarfs Intel’s 24 GB GDDR6, and its 5.32 TB/s bandwidth is over 11 times higher. This makes the MI300 the clear choice for large-scale data processing, high-performance computing, and workloads that demand massive memory footprints and sustained throughput.

The Intel Arc Pro B60 Dual wins in areas that matter for professional graphics and workstation use. It has 20 ray tracing cores, while the AMD card has none listed. Its pixel rate is 192.0 GPixel/s, whereas the MI300 is rated at 0 MPixel/s, meaning the AMD card cannot rasterize at all. Intel also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300 reports N/A for all three APIs. The Intel card has 4x mini-DisplayPort 2.1 outputs, enabling multi-monitor setups, and its higher base and boost clocks (2000 MHz and 2400 MHz) suggest better responsiveness in latency-sensitive tasks.

Architecture Differences

The AMD Instinct MI300 is built on CDNA 3.0, a compute-optimized architecture designed for accelerators. It has 14,080 shading units, 880 texture mapping units, and zero ROPs, reflecting its focus on parallel compute rather than rasterization. The chip, Aqua Vanjaram, is a massive 1017 mm² die with 153,000 million transistors, giving it a transistor density of 150.4M per mm². Its FP16 performance is listed as 47.87 TFLOPS with a 1:1 ratio to FP32, indicating a unified compute path rather than dedicated tensor cores.

The Intel Arc Pro B60 Dual uses Xe2-HPG, a gaming and professional graphics architecture. It has 2,560 shading units, 160 TMUs, and 80 ROPs, plus 20 dedicated ray tracing cores. The BMG-G21 chip is 272 mm² with 19,600 million transistors, resulting in a density of 72.1M per mm². Intel’s FP16 performance is 24.58 TFLOPS at a 2:1 ratio to FP32, meaning the card can double its throughput on half-precision workloads. The architecture supports modern graphics APIs, including DirectX 12 Ultimate and Vulkan 1.4, while the AMD card reports no API support.

The process node is identical (5 nm at TSMC), but the transistor density differs significantly. AMD packs more than twice the transistors per square millimeter, indicating a denser, compute-heavy design. Intel’s lower density suggests a more balanced layout with fixed-function graphics units. The MI300’s lack of ROPs and display outputs confirms its role as a pure compute accelerator, while the Arc Pro B60’s inclusion of ROPs, RT cores, and display outputs marks it as a graphics-capable workstation card.

Specification Differences

The two cards differ across nearly every measured specification. The AMD Instinct MI300 has 14,080 shading units, 880 TMUs, and 0 ROPs, while the Intel Arc Pro B60 Dual has 2,560 shading units, 160 TMUs, and 80 ROPs. The AMD card has no ray tracing cores, whereas Intel includes 20. The MI300’s memory is 128 GB HBM3 with an 8192-bit bus and 5.32 TB/s bandwidth; Intel’s is 24 GB GDDR6 with a 192-bit bus and 456.0 GB/s bandwidth.

Clock speeds differ substantially: the MI300 runs at 1000 MHz base and 1700 MHz boost, while the Arc Pro B60 Dual runs at 2000 MHz base and 2400 MHz boost. The memory clock is 1300 MHz (5.2 Gbps effective) for AMD versus 2375 MHz (19 Gbps effective) for Intel. Pixel rate is 0 MPixel/s for AMD and 192.0 GPixel/s for Intel. Texture rate is 1,496.0 GTexel/s for AMD and 384.0 GTexel/s for Intel. FP32 is 47.87 TFLOPS for AMD and 12.29 TFLOPS for Intel. FP16 is 47.87 TFLOPS (1:1) for AMD and 24.58 TFLOPS (2:1) for Intel.

Power requirements differ: the MI300 has a 600 W TDP with 2x 8-pin connectors and a 1000 W suggested PSU, while the Arc Pro B60 has a 400 W TDP with a single 16-pin connector and an 800 W suggested PSU. The bus interface is PCIe 5.0 x16 for AMD and PCIe 5.0 x8 for Intel. Display outputs are absent on the AMD card, while Intel provides 4x mini-DisplayPort 2.1. The AMD card is 267 mm long and 111 mm tall, while Intel’s is 300 mm long, 110 mm tall, and 40 mm wide (dual-slot). The Intel card has a launch MSRP of 1,199 USD.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between these two cards, and neither has an average benchmark score or nearest rivals listed. However, the specification comparisons provide clear performance deltas. The AMD Instinct MI300 delivers 47.87 TFLOPS of FP32 compute, which is 3.9 times the 12.29 TFLOPS of the Intel Arc Pro B60 Dual. In FP16, AMD’s 47.87 TFLOPS (1:1) is 1.9 times Intel’s 24.58 TFLOPS (2:1), though Intel’s ratio means it gains efficiency in half-precision tasks.

Memory bandwidth is the largest single gap: the MI300’s 5.32 TB/s is roughly 11.7 times the Arc Pro B60’s 456.0 GB/s. Texture rate follows a similar pattern, with AMD’s 1,496.0 GTexel/s being 3.9 times Intel’s 384.0 GTexel/s. The Intel card wins in pixel rate, 192.0 GPixel/s versus 0 MPixel/s, and in clock speeds, with a 400 MHz higher base clock and a 700 MHz higher boost clock.

The AMD card’s transistor count of 153,000 million versus Intel’s 19,600 million represents a 7.8x difference, and its die size of 1017 mm² is 3.7 times larger than Intel’s 272 mm². These structural differences explain the compute gap: AMD has allocated silicon to massive memory buses and compute arrays, while Intel has dedicated area to graphics-specific hardware like RT cores and display engines.

The Verdict

The data indicates two fundamentally different products. The AMD Instinct MI300 is a compute accelerator with no display outputs, no graphics API support, and no rasterization capability. It offers 47.87 TFLOPS FP32, 128 GB HBM3, and 5.32 TB/s bandwidth, positioning it for large-scale parallel compute, AI training, and scientific simulation where memory capacity and throughput dominate. Its 600 W TDP and 1000 W suggested PSU reflect its server-class intent.

The Intel Arc Pro B60 Dual is a professional graphics card with 12.29 TFLOPS FP32, 24 GB GDDR6, and 456.0 GB/s bandwidth. It supports DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4, and includes 20 ray tracing cores plus 4x mini-DisplayPort 2.1 outputs. Its 400 W TDP and 800 W suggested PSU make it more suitable for workstation deployment where display output, graphics APIs, and ray tracing are required.

The choice depends on workload type. The MI300 is for compute-only environments where raw FP32/FP16 throughput and massive memory are critical, and where no display or graphics API is needed. The Arc Pro B60 Dual is for professional visualization, content creation, and CAD workloads that require rasterization, ray tracing, and direct display connectivity. Its higher clocks and graphics features do not compensate for the MI300’s compute advantages, but the AMD card cannot perform any graphics task. Neither card has a benchmark score or percentile ranking in the database, so relative performance against other GPUs cannot be assessed beyond these specifications.
