Intel Arc B770 vs NVIDIA H100 SXM5 64 GB Comparison

The Verdict

The recorded data presents a stark contrast between two accelerators built for entirely different purposes. The Intel Arc B770 is a consumer-oriented graphics card from the Battlemage generation, while the NVIDIA H100 SXM5 64 GB is a dedicated server module from the Hopper generation. Their benchmark percentiles are identical at 50, but this parity masks a fundamental divergence in design philosophy and target workload. The Intel Arc B770 is positioned for gaming and general rasterization, with its display outputs and DirectX 12 Ultimate support. The NVIDIA H100 SXM5, conversely, has no display outputs and lacks a defined DirectX or Vulkan API, indicating its role as a compute accelerator for data centers. The data suggests a buyer should select the Intel part for interactive graphics and consumer workloads, while the NVIDIA module serves purely computational environments where massive memory capacity and tensor throughput are paramount.

Where Each One Wins

The Intel Arc B770 wins in the domain of traditional graphics output. It provides 1x HDMI 2.1a and 3x DisplayPort 2.1 connections, enabling direct display attachment, while the H100 SXM5 offers no outputs whatsoever. The Arc B770 also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it compatible with standard gaming and graphics APIs. Its pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s indicate strong fill-rate capabilities for real-time rendering. The NVIDIA H100 wins in raw compute throughput and memory bandwidth. Its FP32 performance is 66.91 TFLOPS versus 19.66 TFLOPS for the Arc, a 3.4x advantage. Its FP16 performance of 267.6 TFLOPS (4:1) dwarfs the Arc's 39.32 TFLOPS (2:1), a 6.8x difference. The H100's 2.02 TB/s memory bandwidth is 3.9x higher than the Arc's 512.0 GB/s, and its 64 GB HBM3 capacity is four times the Arc's 16 GB GDDR6. The H100 also features 528 tensor cores, which the Arc lacks entirely, making it suited for matrix operations and AI inference.

Architecture Differences

The two chips represent different architectural generations and design intents. The Intel Arc B770 uses the BMG-G31 chip built on the Xe2-HPG architecture, fabricated by TSMC on a 5 nm process. The die size is 368 mm² with an unknown transistor count. The NVIDIA H100 SXM5 uses the GH100 chip on the Hopper architecture, also fabricated by TSMC on a 5 nm process, but with a die size of 814 mm² and 80,000 million transistors, leading to a transistor density of 98.3M per mm². The Intel chip is a dual-slot card with a 225 W TDP, requiring a 1x 6-pin and 1x 8-pin power connector, with a suggested 550 W power supply. The H100 is an SXM module with a 700 W TDP, using an 8-pin EPS connector and requiring a suggested 1100 W power supply. The Intel card connects via PCIe 4.0 x16, while the H100 uses PCIe 5.0 x16. The Intel GPU has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores, but no tensor cores. The H100 has 16896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores, with no dedicated ray tracing cores listed. The memory subsystems diverge completely: the Arc uses a 256-bit GDDR6 bus with 512.0 GB/s bandwidth, while the H100 uses a 3072-bit HBM3 bus with 2.02 TB/s bandwidth. The Intel chip is clocked at a base of 2100 MHz and boost of 2400 MHz, while the H100 runs at 1665 MHz base and 1980 MHz boost, with memory clocks of 2000 MHz (16 Gbps effective) versus 1313 MHz (5.3 Gbps effective). The H100's release date of 2023-03-20 precedes the Arc's 2025-12-31, and the H100 lists a predecessor of Server Ada and a successor of Server Blackwell, while the Arc's predecessor is Alchemist.

Head-to-Head Benchmarks

The head-to-head benchmark data contains no recorded entries, meaning direct comparative scores are absent from the database. However, the specification-level data provides clear performance deltas. The most significant wins for the NVIDIA H100 SXM5 are in FP16 and FP32 compute. The H100's FP16 output of 267.6 TFLOPS (4:1) is 6.8 times the Arc's 39.32 TFLOPS (2:1). In FP32, the H100's 66.91 TFLOPS is 3.4 times the Arc's 19.66 TFLOPS. The texture rate also favors the H100 substantially: 1,045.4 GTexel/s versus 614.4 GTexel/s, a 1.7x advantage. The H100's pixel rate, however, is lower at 47.52 GPixel/s versus the Arc's 307.2 GPixel/s, a 6.5x deficit, reflecting the Arc's rasterization-oriented design. The Arc B770 wins on clock speeds, with a boost clock of 2400 MHz versus the H100's 1980 MHz, a 21% higher boost frequency. The Arc also has more ROPs at 128 versus 24, which contributes to its higher pixel throughput. The H100 compensates with 528 TMUs versus 256, and 16896 shading units versus 4096, a 4.1x shader advantage. The memory bus width difference is extreme: 3072 bits on the H100 versus 256 bits on the Arc, enabling the H100's superior bandwidth. The H100's transistor count of 80,000 million versus the Arc's unknown figure, combined with a larger die (814 mm² versus 368 mm²), indicates a much more complex processor. The H100's tensor core count of 528 versus zero for the Arc makes it the only option for tensor-based workloads in this comparison.
