Intel Arc B770 vs NVIDIA H100 PCIe 96 GB Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the Intel Arc B770 or the NVIDIA H100 PCIe 96 GB. Both entries list an average benchmark score of zero and no head-to-head comparison results. The percentile versus all GPUs is identical for both parts at the 50th percentile, meaning the database currently places neither card above the other in overall performance ranking.

Without direct measurement data, the most reliable performance indicators come from the theoretical throughput figures recorded in the specification sheets. The raw FP32 compute rates show a substantial gap. The NVIDIA H100 PCIe 96 GB delivers 62.08 TFLOPS of single-precision compute, while the Intel Arc B770 produces 19.66 TFLOPS. That places the H100 at roughly 3.16 times the FP32 throughput of the Arc B770, a margin that reflects the H100's server-class positioning against a consumer-oriented graphics card.

The gap widens dramatically in half-precision work. The H100 reaches 248.3 TFLOPS FP16 with a 4:1 ratio, whereas the Arc B770 reaches 39.32 TFLOPS FP16 with a 2:1 ratio. The H100 operates at roughly 6.31 times the FP16 throughput. This disparity matters for AI inference and training workloads, where reduced-precision arithmetic dominates. The H100 also integrates 528 tensor cores specifically for matrix operations; the Arc B770 lists no tensor core count in the database.

Pixel throughput tells a different story. The Arc B770 records 307.2 GPixel/s, while the H100 records 44.09 GPixel/s. The B770 is about 6.97 times faster in pixel fill rate. Texture rate favors the H100, which posts 969.9 GTexel/s against the B770's 614.4 GTexel/s, a 1.58 times advantage. The B770's 128 ROPs versus the H100's 24 ROPs explains the pixel rate inversion; the H100's 528 TMUs versus the B770's 256 TMUs explains the texture rate lead.

Memory bandwidth is not close. The H100's HBM3 stack delivers 3.36 TB/s across a 5120-bit bus, while the B770's GDDR6 memory provides 512.0 GB/s over a 256-bit bus. That is a 6.56 times bandwidth advantage for the H100. Capacity also favors the H100 at 96 GB versus 16 GB, a 6 times difference. These memory figures heavily influence large dataset workloads and high-resolution rendering.

Architecture Differences

The two GPUs come from different design philosophies. The Intel Arc B770 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage generation under the Arc 7 family. Its predecessor is Alchemist. The NVIDIA H100 PCIe 96 GB uses the GH100 chip based on the Hopper architecture, belonging to the Server Hopper generation. Its predecessor is Server Ada and its successor is Server Blackwell.

Both chips are fabricated by TSMC on a 5 nm process node. The die sizes differ significantly. The GH100 measures 814 mm² with 80,000 million transistors, giving a transistor density of 98.3M per mm². The BMG-G31 measures 368 mm² with an unknown transistor count, so density cannot be calculated. The H100's die is 2.21 times larger by area.

Clock behavior differs in direction. The Arc B770 runs a 2100 MHz base clock and boosts to 2400 MHz. The H100 runs a 1665 MHz base clock and boosts to 1837 MHz. The B770's base clock is 435 MHz higher and its boost clock is 563 MHz higher, a notable advantage for a chip with far fewer compute units.

Memory architecture is fundamentally different. The B770 uses 16 GB of GDDR6 over a 256-bit bus. The H100 uses 96 GB of HBM3 over a 5120-bit bus. Memory clock reporting also differs: the B770 lists 2000 MHz with 16 Gbps effective data rate, while the H100 lists 1313 MHz with 5.3 Gbps effective. The HBM3 implementation trades lower clock speed for enormous bus width and bandwidth.

Compute unit organization shows the H100's scale. The H100 has 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The B770 has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The H100 lists no RT cores in the database, while the B770 lists no tensor cores. This separation reflects the H100's data center focus and the B770's graphics focus.

The H100 has no display outputs, which signals its server role. The B770 provides 1x HDMI 2.1a and 3x DisplayPort 2.1. API support also differs: the B770 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H100 lists no DirectX, OpenGL, or Vulkan support in the database.

Power and interface specifications diverge sharply. The H100 is rated at 700 W TDP with a suggested 1100 W power supply and an 8-pin EPS connector. The B770 draws 225 W TDP with a suggested 550 W power supply and uses 1x 6-pin plus 1x 8-pin connectors. The H100 uses PCIe 5.0 x16; the B770 uses PCIe 4.0 x16. Both cards are dual-slot.

The Verdict

The recorded data separates these two cards by role rather than by raw capability alone. The NVIDIA H100 PCIe 96 GB is a server accelerator with no display outputs, no graphics API support, 96 GB of HBM3 memory, 528 tensor cores, and 62.08 TFLOPS FP32. Its 700 W TDP and 1100 W suggested power supply confirm a data center orientation. The Intel Arc B770 is a consumer graphics card with display outputs, full DirectX 12 Ultimate and Vulkan 1.4 support, 32 ray tracing cores, and a 225 W TDP suited to a 550 W power supply.

For compute-heavy tasks such as large-model AI training, the H100's 248.3 TFLOPS FP16, 3.36 TB/s bandwidth, and 96 GB capacity make it the clear choice based on the specification data. The B770 cannot match those figures in any compute metric. For conventional rasterized graphics workloads, the B770's 307.2 GPixel/s pixel rate, higher clock speeds, and graphics API support give it an advantage that the H100 cannot offer, since the H100 lacks display outputs entirely.

Users requiring a GPU for gaming, desktop rendering, or any workload that needs a monitor connection should select the Intel Arc B770. Users running server-side inference, scientific computing, or other throughput-bound parallel workloads should select the NVIDIA H100 PCIe 96 GB. The benchmark database currently shows no direct performance measurements for either card, so these conclusions rest entirely on the architectural and theoretical throughput data recorded in the specification sheets.
