Intel Arc G3 vs NVIDIA H100 PCIe 96 GB Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for the Intel Arc G3 against the NVIDIA H100 PCIe 96 GB. The database lists zero wins for each product in this pairing, and no benchmark scores are available for either GPU. Consequently, any comparison of these two parts must rely entirely on their architectural specifications and the theoretical performance limits those specifications imply.

The Intel Arc G3 delivers a peak FP32 throughput of 6.144 TFLOPS, while the NVIDIA H100 PCIe 96 GB reaches 62.08 TFLOPS in FP32. That places the H100 at approximately 10.1 times the raw FP32 compute of the Arc G3, a gap that reflects their entirely different design targets. In FP16 workloads, the difference widens further: the Arc G3 produces 12.29 TFLOPS using a 2:1 ratio, while the H100 outputs 248.3 TFLOPS using a 4:1 ratio, roughly 20.2 times higher.

Texture and pixel throughput tell a similar story. The Arc G3 manages 96.00 GTexel/s and 48.00 GPixel/s. The H100 counters with 969.9 GTexel/s and 44.09 GPixel/s. The texture rate advantage for the H100 is substantial, over 10 times that of the Arc G3, but the pixel fill rate is actually slightly higher on the Intel part, a 1.09 times margin that stems from the H100's relatively low ROP count of 24 against the Arc G3's 20 ROPs.

Memory bandwidth is the largest single discrepancy. The Arc G3 uses system-shared memory with bandwidth described as system dependent, meaning its effective throughput is tied to whatever platform it is installed into. The H100 carries 96 GB of HBM3 across a 5120-bit bus, delivering 3.36 TB/s of dedicated bandwidth. For memory-bound workloads, the H100 operates in a different performance class entirely, while the Arc G3 remains constrained by the host system's memory subsystem.

The benchmark percentile data places both products at the 50th percentile against all GPUs, but this is a neutral marker given that neither part has recorded benchmark scores in the database. The absence of direct measurements means the percentile field does not reflect actual competitive positioning.

Architecture Differences

The two GPUs come from different manufacturers, different foundries, and different process nodes. Intel fabricates the Arc G3 on a 3 nm process at its own foundry, using the Xe3-LPG architecture built on the Panther Lake chip. NVIDIA produces the H100 PCIe 96 GB on a 5 nm process at TSMC, using the Hopper architecture with the GH100 chip. The H100 contains 80,000 million transistors on an 814 mm² die, giving 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 compute resources diverge sharply. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 ROPs, and 10 ray tracing cores. It has no dedicated tensor cores listed. The H100 has 16896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores, but no ray tracing cores listed. The H100's shading unit count is 13.2 times that of the Arc G3, and its TMU count is 13.2 times higher as well.

Clock behavior also separates the two. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The H100 runs at a base of 1665 MHz and boosts to 1837 MHz. Despite the Arc G3's higher boost clock, its far smaller execution resource pool keeps its total throughput well below the H100's. The H100's memory clock is 1313 MHz with 5.3 Gbps effective data rate, while the Arc G3 relies on system-shared memory with no dedicated memory clock.

The H100 draws 700 W and requires an 8-pin EPS power connector with a suggested PSU of 1100 W. The Arc G3 has a 25 W TDP, uses no power connectors, and is an integrated graphics processor with an IGP bus interface. The H100 is a dual-slot PCIe 5.0 x16 card measuring 268 mm in length and 111 mm in height. The Arc G3 has no physical dimensions listed because it is integrated into the host processor.

API support differs as well. The Arc G3 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H100 lists no API support in the database, consistent with its role as a compute-focused accelerator with no display outputs. The H100 explicitly has no display outputs, while the Arc G3's display outputs are described as portable device dependent.

The Verdict

The data positions these two products in entirely separate categories. The Intel Arc G3 is an integrated graphics processor built on a 3 nm node, drawing 25 W, with no dedicated memory, no tensor cores, and API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The NVIDIA H100 PCIe 96 GB is a dual-slot server accelerator drawing 700 W, carrying 96 GB of HBM3 with 3.36 TB/s bandwidth, 528 tensor cores, and no display outputs or consumer API support.

For raw compute, the H100 dominates every throughput metric except pixel fill rate, where the Arc G3 holds a 48.00 GPixel/s to 44.09 GPixel/s lead. For FP32, FP16, texture rate, memory bandwidth, shading units, TMUs, and tensor core count, the H100 is ahead by multiples ranging from roughly 10 times to over 20 times. The Arc G3's advantages are limited to a smaller process node, a higher boost clock, lower power draw, integrated form factor, and consumer graphics API support.

The H100 is the clear choice for server-side compute, AI training, and inference workloads that can use its tensor cores and massive memory bandwidth. The Arc G3 is the only option for systems requiring an integrated GPU with no additional power connectors, no add-in card slot, and support for consumer graphics APIs. The database records no benchmark scores for either product, so these conclusions follow from the specification data alone.

Where Each One Wins

The Intel Arc G3 wins in power efficiency and integration. Its 25 W TDP requires no power connectors and no separate PSU recommendation, making it suitable for portable devices where display output is dependent on the host platform. It also wins on pixel fill rate with 48.00 GPixel/s against the H100's 44.09 GPixel/s, a modest but real advantage for rasterization-bound tasks. Its higher boost clock of 2400 MHz versus 1837 MHz, its 3 nm process node, and its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 give it a clear edge in consumer graphics environments.

The NVIDIA H100 PCIe 96 GB wins in every compute-heavy category. Its 62.08 TFLOPS FP32 and 248.3 TFLOPS FP16 throughput place it over 10 times and over 20 times ahead of the Arc G3 respectively. Its 969.9 GTexel/s texture rate is more than 10 times the Arc G3's 96.00 GTexel/s. Its 3.36 TB/s memory bandwidth from 96 GB of HBM3 on a 5120-bit bus is in a different class from system-shared memory. Its 16896 shading units, 528 TMUs, and 528 tensor cores provide the execution resources for large-scale parallel workloads. Its 80,000 million transistors on an 814 mm² die indicate the scale of silicon dedicated to server compute.

For AI and machine learning workloads that leverage tensor cores, the H100 is the only one of the two with that hardware. For integrated graphics in a portable device, the Arc G3 is the only one of the two that can function without a discrete slot. The database shows no overlap in their intended use cases, and the specification differences reinforce that separation at every level.
