Intel Arc Pro B70 vs NVIDIA H800 SXM5 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct benchmark scores for either the Intel Arc Pro B70 or the NVIDIA H800 SXM5. Both products show an average benchmark score of zero and a percentile ranking of 50 against all GPUs in the database. The head-to-head benchmark table is empty, and neither product registers any wins in the comparative dataset. This absence of measured results means a traditional score-by-score comparison is not possible from the available information. However, the specification data provides a basis for comparing theoretical peak performance across several compute metrics.

The most substantial difference appears in FP32 throughput. The NVIDIA H800 SXM5 delivers 59.30 TFLOPS, which is roughly 2.6 times the 22.94 TFLOPS of the Intel Arc Pro B70. This is a decisive advantage for the NVIDIA part in single-precision compute workloads. In FP16 operations, the gap widens further. The H800 SXM5 achieves 237.2 TFLOPS with a 4:1 ratio, while the Arc Pro B70 reaches 45.88 TFLOPS with a 2:1 ratio. The NVIDIA accelerator operates at approximately 5.2 times the FP16 throughput of the Intel graphics card, a margin that reflects the server-oriented design of the H800.

Memory bandwidth tells a similar story. The H800 SXM5 uses HBM3 memory across a 5120-bit bus, yielding 3.36 TB/s of bandwidth. The Arc Pro B70 uses GDDR6 on a 256-bit bus, producing 608.0 GB/s. The NVIDIA module provides more than five times the memory bandwidth, which is critical for data-intensive workloads such as large language model inference and training. The Intel card does hold advantages in other metrics. Pixel rate favors the Arc Pro B70 at 358.4 GPixel/s versus 42.12 GPixel/s for the H800 SXM5, a ratio of roughly 8.5 to 1. Texture rate is closer, with the NVIDIA part reaching 926.6 GTexel/s compared to 716.8 GTexel/s for the Intel card, an advantage of about 29%. These figures indicate that the Intel product is oriented toward rasterization-heavy graphics tasks, while the NVIDIA product is optimized for compute and memory throughput.

Clock speeds also differ notably. The Intel Arc Pro B70 runs at a base clock of 2280 MHz and boosts to 2800 MHz. The NVIDIA H800 SXM5 operates at a base of 1095 MHz and boosts to 1755 MHz. The Intel card's higher clocks contribute to its pixel and texture throughput advantages, despite having far fewer shading units. The H800 SXM5 compensates with 16896 shading units versus 4096 on the Arc Pro B70, a 4.1 to 1 difference. TMU counts follow the same pattern: 528 on the NVIDIA part versus 256 on the Intel part. ROP counts reverse this trend, with the Arc Pro B70 featuring 128 ROPs compared to just 24 on the H800 SXM5.

Where Each One Wins

The Intel Arc Pro B70 wins in graphics-oriented metrics. Its pixel rate of 358.4 GPixel/s is substantially higher than the 42.12 GPixel/s of the H800 SXM5, indicating a strong capability for fill-rate-bound rendering workloads. The 128 ROPs on the Intel card support this interpretation, as they enable efficient pixel processing. The Arc Pro B70 also carries display outputs, including 1x HDMI 2.1 and 3x DisplayPort 2.1, while the NVIDIA H800 SXM5 has no display outputs at all. This makes the Intel card suitable for workstation graphics, content creation, and any task requiring direct display connectivity. The dual-slot form factor and single 8-pin power connector also suggest a more conventional installation profile.

The NVIDIA H800 SXM5 wins decisively in compute-heavy scenarios. Its FP32 throughput of 59.30 TFLOPS and FP16 throughput of 237.2 TFLOPS place it in a different performance class for scientific computing, AI training, and inference. The 80 GB of HBM3 memory with 3.36 TB/s bandwidth provides both capacity and speed for large datasets that would exceed the 32 GB GDDR6 frame buffer of the Intel card. The 528 tensor cores on the H800 SXM5 are a clear indicator of its AI-focused design, whereas the Intel Arc Pro B70 lists no tensor cores in its specifications. The SXM Module form factor, 700 W TDP, and 8-pin EPS power connector confirm that this is a server accelerator designed for dense compute clusters, not a desktop graphics card.

The memory capacity difference is significant: 80 GB versus 32 GB. This allows the H800 SXM5 to hold larger models and datasets in memory without spilling to slower storage. The HBM3 memory type also offers substantially lower latency characteristics compared to GDDR6, though latency figures are not provided in the database. The transistor count and die size further differentiate the two: the H800 SXM5 contains 80,000 million transistors on an 814 mm² die, while the Arc Pro B70's transistor count is unknown and its die measures 368 mm². The NVIDIA chip has a transistor density of 98.3 million per square millimeter.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip built on the Xe2-HPG architecture, belonging to the Battlemage Pro Series generation. The NVIDIA H800 SXM5 uses the GH100 chip based on the Hopper architecture, part of the Server Hopper generation. Both are manufactured by TSMC on a 5 nm process node, but the design philosophies diverge sharply.

The Intel architecture allocates 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This API coverage makes it suitable for modern graphics applications, including ray-traced rendering. The NVIDIA architecture allocates 16896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. No ray tracing core count is listed, and no DirectX, OpenGL, or Vulkan support is recorded, which is consistent with a compute-focused server product that lacks a display output path.

The memory subsystems reflect the different targets. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus with a memory clock of 2375 MHz, resulting in 19 Gbps effective speed and 608.0 GB/s bandwidth. The H800 SXM5 uses 80 GB of HBM3 on a 5120-bit bus with a memory clock of 1313 MHz, providing 5.3 Gbps effective speed and 3.36 TB/s bandwidth. The 5120-bit bus is an order of magnitude wider than the 256-bit bus, which explains the massive bandwidth advantage despite lower memory clocks.

The Intel card has a base clock of 2280 MHz and a boost clock of 2800 MHz, while the NVIDIA module runs at 1095 MHz base and 1755 MHz boost. The higher clocks on the Intel part are typical for a graphics card designed for interactive workloads. The NVIDIA part's lower clocks and higher core count indicate a design that scales across many parallel compute units rather than relying on high per-core frequency.

Power requirements also differ. The Intel Arc Pro B70 has a 230 W TDP with a suggested PSU of 550 W. The NVIDIA H800 SXM5 has a 700 W TDP with a suggested PSU of 1100 W. The Intel card is a dual-slot design measuring 267 mm in length, 110 mm in height, and 39 mm in width. The NVIDIA module has no recorded dimensions and uses an SXM form factor, which is a board-to-board connector standard rather than a PCIe slot card.

The release dates are separated by roughly three years. The NVIDIA H800 SXM5 launched on March 20, 2023, with a production status of Active. The Intel Arc Pro B70 has a release date of March 25, 2026, and no production status is recorded. The H800 SXM5 lists its predecessor as Server Ada and its successor as Server Blackwell, indicating its position in NVIDIA's server product line. The Intel card lists no predecessor or successor.

The Verdict

The data supports a clear division of purpose. The Intel Arc Pro B70 is a graphics card in the conventional sense: it has display outputs, a dual-slot form factor, a single 8-pin power connector, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its high pixel rate of 358.4 GPixel/s and 128 ROPs make it suited for rendering tasks that demand fast fill rates. The higher clocks of 2280 MHz base and 2800 MHz boost reinforce this orientation toward interactive graphics workloads.

The NVIDIA H800 SXM5 is a server accelerator with no display capability and no consumer graphics API support. Its strengths lie in raw compute throughput: 59.30 TFLOPS FP32, 237.2 TFLOPS FP16, and 3.36 TB/s of memory bandwidth. The 528 tensor cores and 80 GB of HBM3 memory position it for AI training, inference, and large-scale data processing. The 700 W TDP and SXM Module form factor indicate deployment in data center racks rather than desktop workstations.

Users requiring a workstation graphics card with direct monitor connectivity should select the Intel Arc Pro B70. Users building or operating server infrastructure for compute-intensive workloads should select the NVIDIA H800 SXM5. The benchmark database contains no measured performance data for either product, so these conclusions rest entirely on the specification sheets. The absence of benchmark scores means real-world performance may vary, and neither product can be declared a performance winner in any specific application from the current dataset.
