The Verdict

The recorded data points to a strict division of roles. The AMD Instinct MI300X is the compute-oriented part. It has a Geekbench OpenCL score of 317,994, a 100th percentile ranking, and rival deltas that show it within 8% of the top NVIDIA parts in the database. Its memory subsystem, 192 GB of HBM3 at 5.32 TB/s, and its FP32 rate of 81.72 TFLOPS make it a high-capacity accelerator. The Intel Arc Pro B70, by contrast, has no benchmark score in the database. Its percentile rank of 50 is based on an average score of zero, which means it cannot be compared numerically to the MI300X. What the Arc Pro B70 does have is a full professional display feature set, including 1x HDMI 2.1a and 3x DisplayPort 2.1, a dual-slot form factor, and a 230 W TDP. The MI300X has no display outputs and a 750 W TDP. The choice is clear from the data: the MI300X is for compute workloads where raw throughput and memory capacity dominate, while the Arc Pro B70 is for professional graphics tasks that require display output and a conventional card form factor.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark tests between the MI300X and the Arc Pro B70. The wins counters for both products are zero. The only benchmark available for the MI300X is Geekbench OpenCL at 317,994, and the Arc Pro B70 has no entries in its benchmark array. This absence of shared test data means a direct per-test comparison is impossible. However, the MI300X does have nearest rival data that provides context for its score. It is 5% behind the NVIDIA H200 NVL, 8% behind the NVIDIA B200, 7.5% ahead of the NVIDIA L40S, and 10.7% ahead of the NVIDIA RTX 6000 Ada Generation. Those deltas place the MI300X in the upper tier of the database. The Arc Pro B70 has no rival list, so its standing relative to other professional cards cannot be quantified from the recorded data. The largest measurable advantage belongs to the MI300X in compute throughput, but no direct test confirms that against the Arc Pro B70 specifically.

Architecture Differences

The MI300X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, part of the Instinct (MIx) generation. The Arc Pro B70 uses the Xe2-HPG architecture on the BMG-G31 chip, part of the Battlemage (Pro Series) generation. Both are built on a 5 nm process at TSMC, but the transistor counts differ. The MI300X has 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4M per mm². The Arc Pro B70 has an unknown transistor count on a 368 mm² die, with no density recorded. The MI300X has no ray tracing cores listed and no display outputs, which aligns with its compute-only design. The Arc Pro B70 has 32 ray tracing cores and a full display output suite, aligning with its professional graphics role. The MI300X has zero ROPs, while the Arc Pro B70 has 128. The MI300X has no API support for DirectX, OpenGL, or Vulkan, while the Arc Pro B70 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The FP16 ratio also differs: the MI300X delivers FP16 at a 1:1 ratio relative to FP32, while the Arc Pro B70 delivers FP16 at a 2:1 ratio, meaning its FP16 throughput is double its FP32 throughput. The MI300X predecessor is listed as Radeon Instinct, while the Arc Pro B70 has no predecessor listed. Both have no successor listed.

Where Each One Wins

The AMD Instinct MI300X wins in raw compute and memory capacity. Its FP32 rate of 81.72 TFLOPS is roughly 3.6 times the Arc Pro B70's 22.94 TFLOPS. Its FP16 rate of 81.72 TFLOPS is higher than the Arc Pro B70's 45.88 TFLOPS. Memory capacity is 192 GB versus 32 GB, and memory bandwidth is 5.32 TB/s versus 608.0 GB/s. Texture rate is 2,553.6 GTexel/s versus 716.8 GTexel/s. The MI300X also holds the 100th percentile ranking and a recorded Geekbench OpenCL score of 317,994, while the Arc Pro B70 has no recorded score. The MI300X is the clear choice for compute-heavy workloads that need large memory and high FP32 or FP16 throughput.

The Intel Arc Pro B70 wins in every display and graphics-related field. It has 128 ROPs versus 0, a pixel rate of 358.4 GPixel/s versus 0 MPixel/s, and 32 ray tracing cores versus none. It has display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1), while the MI300X has none. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300X lists N/A for all three APIs. The Arc Pro B70 also runs at higher clocks: 2280 MHz base and 2800 MHz boost, compared to 1000 MHz and 2100 MHz for the MI300X. Its GDDR6 memory runs at 2375 MHz with 19 Gbps effective, which is higher than the MI300X's 1300 MHz with 5.2 Gbps effective, although the MI300X compensates with a far wider bus. The Arc Pro B70 has a 230 W TDP and a suggested PSU of 550 W, both lower than the MI300X's 750 W and 1150 W. Its dual-slot form factor and 267 mm length make it a conventional card for workstation integration. For professional graphics, rendering, or any workload requiring display output, the Arc Pro B70 is the only one of the two with the necessary hardware. The MI300X has no display outputs and no graphics API support, so it cannot drive a display at all. The data divides cleanly: compute capacity belongs to the MI300X, graphics functionality belongs to the Arc Pro B70.
