Intel Arc B770 vs NVIDIA H800 SXM5 Comparison

Intel Arc B770 and NVIDIA H800 SXM5 are both built on a 5 nm TSMC process, but the database separates them into different product contexts. The Arc B770 is a Battlemage (Arc 7) graphics card with 16 GB GDDR6, display outputs, and graphics API support. The H800 SXM5 is a Server Hopper (Hxx) module with 80 GB HBM3, tensor cores, and no display outputs. Neither product has recorded benchmark entries, an average benchmark score above 0, or wins in the database, so the comparison rests on recorded specifications.

Architecture Differences

The two products use different architectures and chips. The Arc B770 uses the BMG-G31 chip with Xe2-HPG architecture, part of the Battlemage (Arc 7) generation. The H800 SXM5 uses the GH100 chip with Hopper architecture, part of the Server Hopper (Hxx) generation. Both are fabricated by TSMC on a 5 nm process, but the H800 die is 814 mm² versus 368 mm² for the Arc B770. The H800 SXM5 carries 80,000 million transistors at a density of 98.3M / mm²; the Arc B770 transistor count is not recorded.

Compute resources differ sharply. The Arc B770 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. The H800 SXM5 has 16896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores, with no RT core count recorded. The Intel card therefore carries a large ROP advantage and the only RT core count in the pair, while the NVIDIA module carries the only tensor core count and a much larger shader and TMU array.

Memory architecture also separates them. The Arc B770 uses 16 GB GDDR6 on a 256 bit bus, producing 512.0 GB/s bandwidth. The H800 SXM5 uses 80 GB HBM3 on a 5120 bit bus, producing 3.36 TB/s bandwidth. The Intel card is a dual-slot PCIe 4.0 x16 card with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. The NVIDIA module is an SXM Module with PCIe 5.0 x16 and no outputs. The Arc B770 records DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the H800 SXM5 has no API support recorded.

Clock and power behavior differ as well. The Arc B770 base clock is 2100 MHz with a 2400 MHz boost; the H800 SXM5 base clock is 1095 MHz with a 1755 MHz boost. The Intel memory clock is 2000 MHz (16 Gbps effective), while the NVIDIA memory clock is 1313 MHz (5.3 Gbps effective). The Arc B770 TDP is 225 W with a 550 W suggested PSU and 1x 6-pin + 1x 8-pin connectors. The H800 SXM5 TDP is 700 W with a 1100 W suggested PSU and an 8-pin EPS connector. Release dates also differ: 2025-12-31 for the Arc B770, 2023-03-20 for the H800 SXM5. The H800 SXM5 is marked Active in production status; the Arc B770 status is not recorded. The Arc B770 predecessor is Alchemist, while the H800 SXM5 predecessor is Server Ada and its successor is Server Blackwell.

Head-to-Head Benchmarks

The database contains no benchmark entries for either GPU. Both entries have an average benchmark score of 0, a 50th percentile standing, and zero wins. Without measured benchmark scores, the recorded throughput rates are the only head-to-head data available.

Compute throughput favors the H800 SXM5 in every recorded scalar category. FP32 is 59.30 TFLOPS for the NVIDIA module versus 19.66 TFLOPS for the Arc B770. FP16 is 237.2 TFLOPS (4:1) versus 39.32 TFLOPS (2:1). Texture rate is 926.6 GTexel/s versus 614.4 GTexel/s. The H800 SXM5 also records 16896 shading units and 528 TMUs, compared with 4096 shading units and 256 TMUs for the Arc B770. Memory bandwidth is 3.36 TB/s versus 512.0 GB/s, and capacity is 80 GB versus 16 GB.

Rasterization throughput favors the Arc B770. Pixel rate is 307.2 GPixel/s for the Intel card versus 42.12 GPixel/s for the NVIDIA module. The Arc B770 records 128 ROPs, while the H800 SXM5 records 24 ROPs. This is the largest Intel advantage in the recorded data. The Arc B770 also has 32 RT cores, while the H800 SXM5 has no RT core count recorded. Tensor throughput is exclusive to the H800 SXM5, with 528 tensor cores versus no tensor core count for the Arc B770. API and display support is exclusive to the Arc B770, which lists DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4, 1x HDMI 2.1a, and 3x DisplayPort 2.1, while the H800 SXM5 lists no outputs and no API support.

Where Each One Wins

Because the database records zero benchmark wins, this section uses specification deltas to separate use cases. The Arc B770 wins in rasterization-oriented roles. Its 307.2 GPixel/s pixel rate is much higher than the 42.12 GPixel/s of the H800 SXM5, and its 128 ROPs compare with 24 ROPs. It is also the only entry with display outputs, with 1x HDMI 2.1a and 3x DisplayPort 2.1, and the only entry with graphics API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its 32 RT cores give it a recorded ray tracing resource that the H800 SXM5 lacks. The lower 225 W TDP and 550 W suggested PSU, plus the dual-slot PCIe 4.0 x16 form factor, place it in conventional client graphics hardware.

The H800 SXM5 wins in compute-oriented roles. Its 59.30 TFLOPS FP32 and 237.2 TFLOPS FP16 (4:1) exceed the 19.66 TFLOPS and 39.32 TFLOPS (2:1) of the Arc B770. Its 528 tensor cores are absent from the Intel entry. Its 926.6 GTexel/s texture rate exceeds 614.4 GTexel/s, and its 16896 shading units and 528 TMUs are far larger than the 4096 shading units and 256 TMUs of the Arc B770. The 80 GB HBM3 memory with 3.36 TB/s bandwidth and 5120 bit bus is a clear capacity and bandwidth advantage over 16 GB GDDR6 with 512.0 GB/s and a 256 bit bus. The SXM Module form factor, PCIe 5.0 x16 interface, 700 W TDP, and 1100 W suggested PSU align with server compute.

The Verdict

The recorded data does not give either product a benchmark win, so the verdict is a specification-based split. The Intel Arc B770 is the appropriate choice for workloads that need rasterization output, display connections, graphics APIs, or ray tracing cores; it is the only product in this pair with those features. The NVIDIA H800 SXM5 is the appropriate choice for workloads that need tensor-core processing, very high FP16 throughput, or very large memory capacity and bandwidth; it is the only product in this pair with tensor cores, 80 GB HBM3, and 3.36 TB/s memory bandwidth. Both entries sit at the 50th percentile with an average benchmark score of 0, which reinforces that the distinction is functional rather than measured.
