Architecture Differences

The Intel Arc G3 and the NVIDIA H100 NVL 94 GB represent fundamentally different design philosophies. The Arc G3 is built on Intel's 3 nm process at Intel's own foundry, while the H100 NVL uses TSMC's 5 nm process. The H100 NVL contains 80,000 million transistors on an 814 mm² die, resulting in a transistor density of 98.3M per mm². The Arc G3's transistor count and die size are listed as unknown in the database.

The memory architecture separates these two products sharply. The Arc G3 relies entirely on system-shared memory, with no dedicated VRAM, no fixed bus width, and bandwidth that varies with the host system. The H100 NVL packs 94 GB of HBM3 on a 6016-bit interface, providing a fixed 3.94 TB/s of bandwidth. This makes the H100 NVL a dedicated compute accelerator, whereas the Arc G3 functions as an integrated GPU.

Compute resources differ by an order of magnitude. The Arc G3 has 1280 shading units, 40 texture mapping units (TMUs), and 20 raster output units (ROPs). The H100 NVL has 16896 shading units, 528 TMUs, and 24 ROPs. The Arc G3 includes 10 ray tracing cores, while the H100 NVL lists no ray tracing cores but includes 528 tensor cores. The H100 NVL's tensor core count matches its TMU count, reflecting its design for tensor-heavy workloads.

The Arc G3 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H100 NVL has no API entries in the database for DirectX, OpenGL, or Vulkan, which aligns with its server-oriented positioning. The Arc G3 is an IGP with no slot width, no power connectors, and display outputs dependent on the portable device. The H100 NVL is a dual-slot card measuring 267 mm in length and 111 mm in height, with PCIe 5.0 x16 interface and no display outputs.

Clock behavior also differs. The Arc G3 runs at a 300 MHz base clock and boosts to 2400 MHz. The H100 NVL has a 1080 MHz base clock and a 1785 MHz boost clock. Memory clocks are system-shared for the Arc G3, while the H100 NVL's memory runs at 1310 MHz with 5.2 Gbps effective speed.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two products, and neither has recorded benchmark scores or average scores above zero. Both sit at the 50th percentile against all GPUs in the database. The absence of measured performance data means direct comparisons must rely on architectural specifications rather than empirical results.

The FP32 compute figures provide the clearest comparison. The H100 NVL delivers 60.32 TFLOPS, which is 9.8 times the Arc G3's 6.144 TFLOPS. This gap is consistent with the shading unit difference: the H100 NVL has 16896 shading units versus 1280 on the Arc G3, a ratio of 13.2 to 1. The FP16 comparison is even more lopsided. The H100 NVL produces 241.3 TFLOPS with a 4:1 ratio, while the Arc G3 produces 12.29 TFLOPS with a 2:1 ratio. The H100 NVL's FP16 output is 19.6 times higher.

Texture and pixel throughput show a mixed picture. The H100 NVL achieves 942.5 GTexel/s, which is 9.8 times the Arc G3's 96.00 GTexel/s. However, the Arc G3 has a higher pixel rate: 48.00 GPixel/s versus 42.84 GPixel/s for the H100 NVL. This is notable because the Arc G3 has only 20 ROPs compared to the H100 NVL's 24 ROPs, but the Arc G3's much higher boost clock compensates in pixel throughput calculations.

Memory bandwidth differences are extreme. The H100 NVL's 3.94 TB/s is orders of magnitude above the Arc G3's system-dependent bandwidth, which has no fixed figure in the database. For workloads that saturate memory, the H100 NVL's dedicated HBM3 provides a decisive advantage that the Arc G3 cannot match regardless of host memory speed.

Power efficiency can be inferred from the specification data. The Arc G3 draws 25 W, while the H100 NVL draws 400 W. The H100 NVL delivers 9.8 times the FP32 throughput while consuming 16 times the power, meaning the Arc G3 has better FP32 performance per watt based on these figures. However, the H100 NVL's FP16 throughput per watt is higher: it delivers 241.3 TFLOPS at 400 W versus 12.29 TFLOPS at 25 W, which is 0.60 TFLOPS per watt versus 0.49 TFLOPS per watt respectively.

The Arc G3's pixel rate advantage, 48.00 GPixel/s versus 42.84 GPixel/s, indicates that for rasterization-bound tasks, the integrated part can outperform the server accelerator on that specific metric. This is a narrow win but a real one in the recorded data.

The Verdict

The data points to two different usage domains with minimal overlap. The Intel Arc G3 is an integrated processor designed for portable devices, with system-shared memory, no power connectors, and display outputs dependent on the host. Its 25 W TDP and 3 nm process make it suitable for power-constrained environments where a dedicated GPU is not an option.

The NVIDIA H100 NVL 94 GB is a server-class accelerator with a dual-slot form factor, 400 W TDP, 8-pin EPS power connector, and an 800 W suggested PSU. Its 94 GB of HBM3 and 3.94 TB/s bandwidth target large-scale compute workloads. The absence of display outputs and graphics API support confirms its compute-only role.

For FP32 and FP16 workloads, the H100 NVL shows a 9.8x and 19.6x advantage respectively. For pixel fill rate, the Arc G3 shows a 12% advantage. The Arc G3 also has better FP32 performance per watt, delivering 0.246 TFLOPS per watt versus 0.151 TFLOPS per watt for the H100 NVL. The H100 NVL counters with better FP16 performance per watt at 0.603 TFLOPS per watt versus 0.492 TFLOPS per watt.

Users requiring tensor core operations will find 528 tensor cores on the H100 NVL, while the Arc G3 lists none. Users requiring ray tracing will find 10 RT cores on the Arc G3, while the H100 NVL lists none. These are mutually exclusive feature sets.

The release dates place the Arc G3 in 2026-05-31 and the H100 NVL in 2023-03-20. The H100 NVL has a predecessor, Server Ada, and a successor, Server Blackwell, indicating an established product line. The Arc G3 has no predecessor or successor listed, suggesting a new entry in the Arc Graphics-M series.

The physical specifications confirm the intended environments. The H100 NVL measures 267 mm by 111 mm and occupies two slots. The Arc G3 is an IGP with no dimensions recorded, no slot width, and no power connectors. The bus interfaces reflect this: PCIe 5.0 x16 for the H100 NVL versus IGP for the Arc G3.
