AMD Instinct MI350X vs Intel Arc Pro B50 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Instinct MI350X and the Intel Arc Pro B50. The database lists no shared test results where both GPUs ran the same workload. This absence of overlapping benchmarks is itself a meaningful indicator: the two products are aimed at entirely different segments, and their performance envelopes never intersect in the measured suite.

The Intel Arc Pro B50 has a complete set of eight benchmark scores, while the AMD Instinct MI350X has no recorded benchmark scores at all. The MI350X shows an average benchmark score of zero and a percentile rank of 50 among all GPUs, which reflects its position as a compute accelerator without consumer benchmark coverage. The Arc Pro B50, by contrast, delivers a 3DMark Steel Nomad DX12 score of 1604, a PassMark G3D score of 12553, and a PassMark GPU Compute score of 6037. Its average benchmark score sits at 2660, placing it at the 17th percentile of all GPUs.

The nearest rivals for the Arc Pro B50 in the database are all NVIDIA parts. The GeForce GT 1030 scores 2662, which is 0.1% ahead of the Arc Pro B50. The Quadro K1100M scores 2664, 0.2% ahead. The GeForce GT 440 scores 2645, which is 0.6% behind. The GeForce RTX 5070 SUPER scores 2690, 1.1% ahead. These deltas are all within roughly one percentage point, indicating that the Arc Pro B50 clusters tightly with both entry-level and mid-range NVIDIA offerings in the database's aggregated scoring.

Because the MI350X has no benchmarks, no direct wins can be assigned to either product. The wins counter in the database shows zero for both items. The analysis must therefore rely on architectural and specification differences to characterize the performance gap.

The Verdict

The data clearly separates these two GPUs into distinct categories with no overlap in intended use. The AMD Instinct MI350X is a compute accelerator with no display outputs, no graphics API support, and a thermal design power of 1000 W. The Intel Arc Pro B50 is a professional graphics card with four mini-DisplayPort 2.1 outputs, DirectX 12 Ultimate support, OpenGL 4.6, Vulkan 1.4, and a 70 W thermal design power.

For rendering, rasterization, or any graphics workload that requires a display connection, the Arc Pro B50 is the only viable option between the two. Its 16 GB of GDDR6 memory, 128-bit bus, and 224.0 GB/s bandwidth support professional visualization tasks. Its 2048 shading units, 128 texture mapping units, 16 render output units, and 16 ray tracing cores give it a complete graphics pipeline. The pixel rate of 41.60 GPixel/s and texture rate of 332.8 GTexel/s confirm functional rasterization capacity.

For compute-heavy workloads such as AI training, large-scale matrix operations, or massive data processing, the MI350X dominates on raw specification. Its 288 GB of HBM3e memory on an 8192-bit bus delivers 8.19 TB/s of bandwidth, which is 36.6 times the bandwidth of the Arc Pro B50. The MI350X has 16,384 shading units, 1024 texture mapping units, and delivers 72.09 TFLOPS of FP32 performance, which is 6.77 times the Arc Pro B50's 10.65 TFLOPS. The MI350X also matches FP16 at 72.09 TFLOPS with a 1:1 ratio, whereas the Arc Pro B50 reaches 21.30 TFLOPS at a 2:1 ratio.

The data supports a simple conclusion: the Arc Pro B50 is for graphics output and visualization; the MI350X is for compute acceleration without any display capability. Neither product substitutes for the other.

Where Each One Wins

The AMD Instinct MI350X wins decisively in every compute-oriented category recorded in the database. Its FP32 throughput of 72.09 TFLOPS is nearly seven times that of the Arc Pro B50. Its FP16 performance of 72.09 TFLOPS at a 1:1 ratio means it does not sacrifice precision for speed, whereas the Arc Pro B50's FP16 runs at half rate relative to FP32. The MI350X memory subsystem is in a different class: 288 GB of HBM3e with 8.19 TB/s bandwidth supports datasets that would completely exhaust the Arc Pro B50's 16 GB frame buffer. The 8192-bit bus width allows the MI350X to feed its 16,384 shading units without bottlenecks. The texture rate of 2,252.8 GTexel/s indicates sustained throughput for texture-heavy compute kernels.

The Intel Arc Pro B50 wins in every graphics-oriented category. It has a functional pixel pipeline with 16 render output units and a pixel rate of 41.60 GPixel/s, while the MI350X has zero render output units and zero pixel rate. The Arc Pro B50 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, enabling modern graphics workloads. Its four mini-DisplayPort 2.1 outputs allow connection to professional displays. The 16 ray tracing cores provide hardware acceleration for ray-traced rendering, a feature entirely absent from the MI350X. The Arc Pro B50 also operates at a 70 W TDP with a 250 W suggested power supply, making it deployable in standard workstation configurations, while the MI350X requires a 1000 W thermal envelope and a 1400 W power supply.

The Arc Pro B50 has a higher boost clock at 2600 MHz versus 2200 MHz, and a higher base clock at 1700 MHz versus 1000 MHz. It also has a higher effective memory data rate at 14 Gbps versus 8 Gbps. These clock advantages matter for latency-sensitive graphics tasks where the MI350X's massive parallel throughput does not translate to frame output.

The database's benchmark data only covers the Arc Pro B50. Its PassMark G3D score of 12553 and 3DMark Steel Nomad score of 1604 quantify its graphics capability. The PassMark GPU Compute score of 6037 shows a modest compute side. The MI350X has no comparable scores, which reinforces its positioning as a non-benchmarked accelerator. The Arc Pro B50's nearest rival, the NVIDIA GeForce RTX 5070 SUPER, sits only 1.1% ahead in average score, placing the Arc Pro B50 in a competitive graphics performance band. The MI350X, with no rivals listed, occupies an uncontested compute tier.
