AMD Instinct MI350P vs Intel Arc Pro B70 Comparison

Where Each One Wins

The database records no benchmark scores for either the AMD Instinct MI350P or the Intel Arc Pro B70. Both cards sit at the 50th percentile among all GPUs in the database, with an average benchmark score of zero for each. Without recorded head-to-head results, the data does not establish a categorical winner in any workload category. What the data does show is a clear division of purpose. The Instinct MI350P is a compute accelerator with no display outputs, a 600 W power target, and memory capacity aimed at large data residency. The Arc Pro B70 is a professional graphics card with four display outputs, a 230 W power target, and half the memory of the MI350P. The wins are structural rather than performance-based: the MI350P wins in memory capacity, memory bandwidth, and FP32 throughput on paper; the Arc Pro B70 wins in rasterization features, API support, and practical workstation integration.

Architecture Differences

The two accelerators come from different architectural lineages. The Instinct MI350P uses the CDNA 4.0 architecture, built on a 3 nm TSMC process with 73,000 million transistors on a 1190 mm² die. The transistor density works out to 61.3 million transistors per square millimeter. The Intel Arc Pro B70 uses the Xe2-HPG architecture, built on a 5 nm TSMC process with a 368 mm² die size. Transistor count is not recorded for the Intel part.

The CDNA 4.0 design is compute-oriented. The MI350P has 8192 shading units, 512 texture mapping units, and zero ROPs. Pixel rate is listed as 0 MPixel/s, and texture rate is 1,126.4 GTexel/s. It has no ray tracing cores and no tensor core count recorded. FP16 throughput matches FP32 at a 1:1 ratio, both at 36.04 TFLOPS. This indicates the chip does not use a doubled FP16 path; it treats FP16 and FP32 with equal throughput.

The Xe2-HPG design is graphics-oriented. The Arc Pro B70 has 4096 shading units, 256 texture mapping units, and 128 ROPs. It includes 32 ray tracing cores. Pixel rate is 358.4 GPixel/s and texture rate is 716.8 GTexel/s. FP32 throughput is 22.94 TFLOPS, while FP16 throughput is 45.88 TFLOPS at a 2:1 ratio, meaning the FP16 path runs at double the FP32 rate. The B70 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI350P lists N/A for DirectX, OpenGL, and Vulkan support, reinforcing that it is not designed for graphics rendering.

Process node differences matter here. The MI350P uses TSMC's 3 nm node; the Arc Pro B70 uses TSMC's 5 nm node. Both cards use PCIe 5.0 x16 as the bus interface. The MI350P is physically larger in height and width: 111 mm tall and 40 mm wide versus 110 mm tall and 39 mm wide for the B70. Both are 267 mm long and dual-slot cards.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark entries between these two parts. Wins counts stand at zero for both. As such, the numerical comparison below uses the recorded specification data rather than measured performance results.

The largest recorded advantage for the MI350P is memory bandwidth. The AMD card lists 8.19 TB/s of bandwidth across an 8192-bit bus using HBM3e memory. The Intel card lists 608.0 GB/s across a 256-bit bus using GDDR6. The MI350P provides more than thirteen times the memory bandwidth of the B70 on paper. Memory capacity also differs substantially: 144 GB versus 32 GB.

FP32 throughput favors the MI350P at 36.04 TFLOPS versus 22.94 TFLOPS for the B70. That is roughly 57% higher FP32 throughput for the AMD part. FP16 throughput is a different story. The MI350P delivers 36.04 TFLOPS FP16, while the Arc Pro B70 delivers 45.88 TFLOPS FP16. The Intel card has about 27% higher FP16 throughput than the AMD card. This is a direct consequence of the 2:1 FP16 ratio on the Xe2-HPG architecture versus the 1:1 ratio on CDNA 4.0.

Texture rate favors the MI350P: 1,126.4 GTexel/s against 716.8 GTexel/s. Pixel rate is inverted: the B70 delivers 358.4 GPixel/s while the MI350P is listed at 0 MPixel/s, confirming the AMD part has no raster output stage. Clock speeds differ as well. The MI350P runs a 1000 MHz base and 2200 MHz boost. The B70 runs a 2280 MHz base and 2800 MHz boost. The Intel card operates at higher clocks, but the AMD card compensates with more shading units and a wider memory interface.

Power draw is a significant recorded difference. The MI350P has a 600 W TDP with a suggested 1000 W power supply and a single 16-pin connector. The Arc Pro B70 has a 230 W TDP with a suggested 550 W power supply and a single 8-pin connector. The B70 is the more power-efficient design per the recorded figures, though efficiency ratios are not directly listed in the database.

The Verdict

The recorded data points to two different products for two different workloads. The AMD Instinct MI350P is a compute accelerator with no graphics output, no raster pipeline, and no graphics API support. Its advantages are memory capacity, memory bandwidth, and FP32 throughput. The 144 GB HBM3e pool and 8.19 TB/s bandwidth exist to keep large models and datasets resident on the card. The 600 W TDP and 1000 W suggested power supply reflect a device meant for a server chassis with dedicated power delivery.

The Intel Arc Pro B70 is a professional workstation GPU. It has a full graphics feature set: 128 ROPs, 32 ray tracing cores, DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4, and four display outputs. Its FP16 throughput exceeds the MI350P's, and its 230 W TDP with a 550 W suggested power supply makes it feasible in a standard workstation. The launch MSRP is 949 USD, recorded once here.

The data does not rank one as superior. The MI350P wins on raw compute scale and memory bandwidth. The B70 wins on graphics features, FP16 throughput, and power efficiency. A builder selecting between them should base the choice on whether the workload needs rendering output or massive memory residency. The MI350P is the data-center compute part; the B70 is the professional graphics part. The recorded specifications match those roles cleanly.
