Intel Arc Pro B70 vs NVIDIA H800 PCIe 80 GB Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark scores for the Intel Arc Pro B70 versus the NVIDIA H800 PCIe 80 GB. Both products sit at the 50th percentile in the database's overall GPU rankings, with an average benchmark score of 0, which indicates that neither part has accumulated sufficient standardized test results to establish a comparative performance delta. Without measured scores, the database cannot produce a win count for either side, and the winsA and winsB fields remain at zero.

The absence of benchmark data does not mean the two cards are equivalent. It means the database has not yet recorded comparable workloads for these specific SKUs. The Intel Arc Pro B70 appears to be a newly released professional graphics solution, while the NVIDIA H800 PCIe 80 GB has been in the database since early 2023 as an active server accelerator. The H800's predecessor and successor are listed as Server Ada and Server Blackwell, respectively, confirming its placement in a multi-generation product line. The Arc Pro B70 has no predecessor or successor listed, suggesting it is a first-generation entry in its professional lineup.

What can be analyzed from the existing records are the architectural and specification differences that would influence future benchmark outcomes. The NVIDIA H800 delivers 51.22 TFLOPS of FP32 compute, more than double the Arc Pro B70's 22.94 TFLOPS. In FP16, the gap widens dramatically: the H800 reaches 204.9 TFLOPS with a 4:1 ratio, while the Arc Pro B70 achieves 45.88 TFLOPS with a 2:1 ratio. Memory bandwidth favors the H800 at 2.04 TB/s, versus 608.0 GB/s for the Arc Pro B70. Texture rate is slightly higher on the H800 at 800.3 GTexel/s, compared to 716.8 GTexel/s. Pixel rate is the one clear victory for Intel, with 358.4 GPixel/s versus 42.12 GPixel/s, a difference driven by the Arc Pro B70's 128 ROPs against the H800's 24 ROPs.

Where Each One Wins

The data indicates a workload split based on hardware capabilities. The Intel Arc Pro B70 wins in rasterization-heavy tasks because of its 128 ROPs and 358.4 GPixel/s pixel throughput. The H800's 24 ROPs and 42.12 GPixel/s place it far behind in any scenario that requires rapid pixel output, such as high-resolution framebuffer operations or traditional 3D rendering pipelines. The Arc Pro B70 also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it a functional graphics card with display outputs including 1x HDMI 2.1a and 3x DisplayPort 2.1. The H800 lists no display outputs and no graphics API support, confirming its role as a compute-only accelerator.

The NVIDIA H800 wins in compute throughput and memory capacity. Its 51.22 TFLOPS FP32, 204.9 TFLOPS FP16, and 456 tensor cores position it for dense matrix operations, AI inference, and scientific simulation. The 80 GB HBM2e memory with a 5120-bit bus and 2.04 TB/s bandwidth provides 2.5 times the capacity and 3.35 times the bandwidth of the Arc Pro B70's 32 GB GDDR6 on a 256-bit bus. Texture-heavy workloads see a modest advantage for the H800 at 800.3 GTexel/s versus 716.8 GTexel/s. The H800 also has 14,592 shading units, nearly 3.6 times the Arc Pro B70's 4,096, and 456 TMUs against 256.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip based on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation. It is built on a 5 nm process at TSMC with a die size of 368 mm². The H800 uses the GH100 chip based on the Hopper architecture, part of the Server Hopper (Hxx) generation, also on a 5 nm TSMC process but with a die size of 814 mm². The H800's transistor count is listed at 80,000 million, while the Arc Pro B70's transistor count is unknown. Transistor density for the H800 is 98.3M per mm², a figure not available for the Intel part.

Memory configurations diverge sharply. The Arc Pro B70 uses 32 GB of GDDR6 at 2375 MHz with an effective 19 Gbps rate, across a 256-bit bus, producing 608.0 GB/s. The H800 uses 80 GB of HBM2e at 1593 MHz with 3.2 Gbps effective, across a 5120-bit bus, producing 2.04 TB/s. The memory clock and bus width differences reflect fundamentally different design targets: GDDR6 for graphics workstations versus HBM2e for server compute.

Core counts differ in every category. The Arc Pro B70 has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The H800 has 14,592 shading units, 456 TMUs, 24 ROPs, no listed ray tracing cores, and 456 tensor cores. The Arc Pro B70 lists no tensor cores, which is consistent with its professional graphics positioning rather than an AI accelerator role. Clock speeds favor Intel: 2280 MHz base and 2800 MHz boost versus 1095 MHz base and 1755 MHz boost for NVIDIA. The H800's lower clocks are offset by its massive core count and memory bandwidth.

Power and physical characteristics also differ. The Arc Pro B70 has a 230 W TDP with a 1x 8-pin power connector and a suggested 550 W PSU. The H800 has a 350 W TDP with a 1x 16-pin connector and a suggested 750 W PSU. Both are dual-slot cards. The Arc Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width. The H800 measures 268 mm in length and 111 mm in height, with no width listed. Both use PCIe 5.0 x16 interfaces.

The Verdict

Based strictly on the recorded data, the NVIDIA H800 PCIe 80 GB is the compute-dominant product. Its FP32 throughput of 51.22 TFLOPS, FP16 throughput of 204.9 TFLOPS, 456 tensor cores, and 80 GB HBM2e memory with 2.04 TB/s bandwidth make it the clear choice for AI, scientific, and high-throughput compute workloads. The H800's 14,592 shading units and 456 TMUs support its shader-heavy processing capabilities, though its 24 ROPs and 42.12 GPixel/s pixel rate limit its rasterization performance.

The Intel Arc Pro B70 is the graphics-oriented product. Its 128 ROPs and 358.4 GPixel/s pixel rate, combined with full display outputs and graphics API support, make it suitable for workstation rendering, visualization, and any task requiring frame output. Its 32 GB GDDR6 memory and 608.0 GB/s bandwidth are substantial but not competitive with the H800's memory subsystem. The Arc Pro B70's 22.94 TFLOPS FP32 and 45.88 TFLOPS FP16 are adequate for professional graphics but fall well short of the H800.

The data also shows clear positioning signals. The H800 has no display outputs and no API support, indicating a server accelerator. The Arc Pro B70 has a launch MSRP of 949 USD, a 230 W TDP, and a 550 W suggested PSU, while the H800 has a 350 W TDP and a 750 W suggested PSU. The H800 is listed as Active in production status with a known predecessor (Server Ada) and successor (Server Blackwell). The Arc Pro B70 has no production status, predecessor, or successor listed. Different use cases, different architectures, and different hardware priorities: the database records two professional accelerators that target non-overlapping workloads.
