Intel Arc B770 vs NVIDIA H20 NVL16 Comparison

The Verdict

The recorded data positions the Intel Arc B770 and NVIDIA H20 NVL16 as two entirely different tools, despite both being placed at the 50th percentile among all GPUs in the database. The Intel Arc B770 is a consumer-facing graphics card built for rendering and interactive workloads, while the NVIDIA H20 NVL16 is a server accelerator with no display outputs, designed for compute-heavy environments. The data shows no direct head-to-head benchmark wins for either product, so the choice rests entirely on which class of work the user is performing. For gaming, DirectX 12 Ultimate support, or any task requiring a display connection, the Intel Arc B770 is the only viable option from this pair. For massive memory capacity, high-bandwidth compute, or Tensor Core acceleration, the NVIDIA H20 NVL16 is the clear selection. The Arc B770 offers a familiar dual-slot PCIe card with standard power connectors, while the H20 NVL16 is an SXM module requiring a server chassis and an 800 W suggested PSU. The data indicates these products do not compete in the same market segment; they serve different buyers entirely.

Architecture Differences

The Intel Arc B770 uses the BMG-G31 chip built on the Xe2-HPG architecture, belonging to the Battlemage (Arc 7) generation and the Alchemist predecessor line. It is fabricated on a 5 nm process at TSMC with a die size of 368 mm². The NVIDIA H20 NVL16 uses the GH100 chip on the Hopper architecture, part of the Server Hopper (Hxx) generation with the Server Ada predecessor. It is also fabricated on a 5 nm process at TSMC, but the die measures 814 mm² and contains 80,000 million transistors, yielding a density of 98.3M / mm². The Arc B770's transistor count is listed as unknown, which limits direct density comparisons. The H20 NVL16 uses HBM3 memory with a 6144-bit bus, while the Arc B770 uses GDDR6 with a 256-bit bus. The Intel card incorporates 32 dedicated ray tracing cores, whereas the H20 NVL16 lists no ray tracing cores but provides 312 Tensor Cores. The Arc B770 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H20 NVL16 reports N/A for all three APIs, indicating it is not intended for graphics rendering in the traditional sense. The H20 NVL16 uses a PCIe 5.0 x16 interface, one generation newer than the Arc B770's PCIe 4.0 x16.

Where Each One Wins

The Intel Arc B770 wins in any scenario that requires a physical display output. It provides 1x HDMI 2.1a and 3x DisplayPort 2.1 connections, while the NVIDIA H20 NVL16 has no outputs at all. The Arc B770 also supports DirectX 12 Ultimate and Vulkan 1.4, making it the only choice for gaming or graphics applications that rely on these APIs. Its dual-slot form factor and 1x 6-pin plus 1x 8-pin power connectors fit standard desktop power supplies, with a suggested 550 W PSU. The H20 NVL16 wins in memory capacity and bandwidth: 96 GB of HBM3 compared to 16 GB of GDDR6, and 4.03 TB/s bandwidth versus 512.0 GB/s. The H20 NVL16 also delivers higher raw compute in FP32 (39.54 TFLOPS vs 19.66 TFLOPS) and FP16 (79.07 TFLOPS vs 39.32 TFLOPS, both at 2:1 ratio). The Tensor Cores on the H20 NVL16 provide acceleration for AI and deep learning workloads, a feature entirely absent from the Arc B770. The H20 NVL16's SXM module form factor and 400 W TDP indicate a server environment, whereas the Arc B770's 225 W TDP fits a desktop tower. The production status of the H20 NVL16 is listed as Active, while the Arc B770 does not report a production status, suggesting the NVIDIA part is currently available in the market.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results between the Intel Arc B770 and the NVIDIA H20 NVL16, and neither product has individual benchmark scores or nearest rivals listed. The wins count for both products is zero, meaning the data does not provide a direct performance comparison. What the data does show is a dramatic difference in memory architecture: the H20 NVL16's 4.03 TB/s bandwidth is approximately 7.9 times the Arc B770's 512.0 GB/s. The compute throughput also favors the NVIDIA part by a factor of roughly 2.0 in FP32 (39.54 TFLOPS vs 19.66 TFLOPS) and 2.0 in FP16 (79.07 TFLOPS vs 39.32 TFLOPS). The pixel rate tells the opposite story, with the Arc B770 delivering 307.2 GPixel/s compared to the H20 NVL16's 47.52 GPixel/s, a 6.5 times advantage for the Intel card.
