Architecture Differences

The Intel Arc G3 and NVIDIA H200 SXM 141 GB occupy opposite ends of the hardware spectrum, not just in performance class but in fundamental design philosophy. The Arc G3 is an integrated graphics processor, or IGP, built into the Panther Lake chip, while the H200 is a standalone SXM Module designed for server deployments. This distinction shapes every other architectural decision.

The manufacturing process separates them clearly. Intel fabricates the Arc G3 on a 3 nm node at its own foundry, while NVIDIA uses TSMC's 5 nm process for the GH100 chip. The H200's die size is recorded at 814 mm² with 80,000 million transistors, yielding a density of 98.3M per mm². The Arc G3's die size and transistor count are not recorded in the database, leaving its physical design partially opaque, but its 3 nm process suggests a much smaller footprint.

Compute resources differ by an order of magnitude. The Arc G3 carries 1280 shading units, 40 texture mapping units, and 20 ROPs, along with 10 ray tracing cores. The H200 fields 16896 shading units, 528 TMUs, and 24 ROPs, with 528 tensor cores but no dedicated RT cores listed. The H200's tensor core array signals its AI and data center focus, while the Arc G3's RT cores indicate a graphics-oriented design.

Clock behavior reveals different priorities. The Arc G3 boosts from a 300 MHz base to 2400 MHz, a wide dynamic range typical of power-sensitive integrated parts. The H200 starts at 1500 MHz and boosts to 1980 MHz, a narrower range that suggests sustained throughput over burst performance. The H200's memory clock of 1593 MHz (6.4 Gbps effective) drives its HBM3e stack, whereas the Arc G3's memory clock is described simply as System Shared.

The API support tells a similar story. The Arc G3 exposes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it a functional graphics solution. The H200 lists N/A for all graphics APIs, confirming that its role does not include traditional rendering workloads. Display outputs follow the same logic: the Arc G3's outputs are Portable Device Dependent, while the H200 has no outputs at all.

Where Each One Wins

The Intel Arc G3 wins in scenarios where power efficiency and portability dominate. Its 25 W TDP allows operation without any power connectors, and its IGP bus interface means it requires no discrete card slot. The wide boost range from 300 MHz to 2400 MHz gives it flexibility for bursty, latency-sensitive graphics tasks. Its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 makes it a viable rendering engine for portable devices.

The NVIDIA H200 SXM 141 GB wins in raw compute and memory-intensive environments. Its 141 GB of HBM3e memory with 4.89 TB/s bandwidth dwarfs any system-shared memory arrangement. The 66.91 TFLOPS of FP32 compute and 133.8 TFLOPS of FP16 compute place it in a different performance class entirely. The 528 tensor cores provide dedicated hardware for matrix operations, which the Arc G3 lacks entirely.

The data indicates a clean split: the Arc G3 is a graphics processor for integrated settings, while the H200 is a compute accelerator for server racks. Neither device encroaches on the other's territory. The Arc G3's lack of dedicated memory means its performance scales with the host system, while the H200's fixed 141 GB pool ensures predictable capacity. The H200's predecessor is listed as Server Ada and its successor as Server Blackwell, confirming its position in a dedicated server product line. The Arc G3 belongs to the Arc Graphics-M (Panther Lake) generation, aimed at mobile or integrated platforms.

Specification Differences

The recorded specifications diverge on nearly every measurable field. The process node differs: 3 nm for Intel versus 5 nm for TSMC. The H200 has a recorded transistor count of 80,000 million, a die size of 814 mm², and a density of 98.3M per mm²; the Arc G3 records none of these values.

Clock speeds: the Arc G3 uses 300 MHz base and 2400 MHz boost; the H200 uses 1500 MHz base and 1980 MHz boost. Memory: the Arc G3 is System Shared across size, type, and bus width, with System Dependent bandwidth; the H200 uses 141 GB of HBM3e on a 6144-bit bus with 4.89 TB/s bandwidth.

Compute units: the Arc G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores; the H200 has 16896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The H200 has no RT cores listed, and the Arc G3 has no tensor cores listed.

Rates: the Arc G3 achieves 48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate; the H200 achieves 47.52 GPixel/s and 1,045.4 GTexel/s. FP32 compute: 6.144 TFLOPS for the Arc G3 versus 66.91 TFLOPS for the H200. FP16: 12.29 TFLOPS (2:1) versus 133.8 TFLOPS (2:1).

Power and form factor: 25 W TDP, IGP slot width, no power connectors, and IGP bus interface for the Arc G3; 700 W TDP, SXM Module slot width, 8-pin EPS connector, 1100 W suggested PSU, and PCIe 5.0 x16 bus interface for the H200. Display outputs: Portable Device Dependent versus No outputs. APIs: the Arc G3 lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the H200 lists N/A for all three.

Release dates: the Arc G3 is dated 2026-05-31, while the H200 is dated 2024-11-17. Production status for both is Active. Neither device has a recorded launch MSRP.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between the Intel Arc G3 and the NVIDIA H200 SXM 141 GB. Both parts also have empty benchmark arrays, zero average benchmark scores, and no nearest rivals listed. The percentile versus all GPUs is recorded as 50 for both, which offers no differentiation.

Despite the absence of direct measurements, the specification data allows for computed comparisons. The H200 delivers 66.91 TFLOPS of FP32 compute against the Arc G3's 6.144 TFLOPS, a difference of roughly 10.9 times. The FP16 figures show a similar ratio: 133.8 TFLOPS versus 12.29 TFLOPS, again about 10.9 times. These are the largest recorded disparities between the two.

Texture rate favors the H200 heavily at 1,045.4 GTexel/s versus 96.00 GTexel/s, approximately 10.9 times higher as well. Pixel rate, however, is nearly identical: 47.52 GPixel/s for the H200 versus 48.00 GPixel/s for the Arc G3. The Arc G3 actually holds a marginal lead here, though the difference is less than one percent and likely reflects the H200's small 24 ROP count relative to its other resources.

Memory bandwidth presents the most extreme gap. The H200's 4.89 TB/s dwarfs the Arc G3's System Dependent figure, which cannot be quantified from the database. The H200's 141 GB dedicated capacity versus System Shared memory reinforces this separation. The Arc G3's boost clock of 2400 MHz exceeds the H200's 1980 MHz by 420 MHz, but the H200's base clock of 1500 MHz is five times the Arc G3's 300 MHz floor.

The transistor counts, where recorded, emphasize the scale difference: 80,000 million for the H200 against an unknown figure for the Arc G3. The H200's 16896 shading units compared to 1280 for the Arc G3 represents a 13.2 times advantage, the largest ratio in the compute unit comparison. Texture mapping units follow at 528 versus 40, a 13.2 times difference, while ROPs are close at 24 versus 20.

The Verdict

The recorded data supports a straightforward selection based on workload type. The Intel Arc G3 fits integrated, power-constrained environments. Its 25 W TDP, lack of power connectors, IGP bus interface, and Portable Device Dependent display outputs place it firmly in the mobile or embedded segment. The DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support make it a functional graphics device, and its 10 RT cores provide hardware ray tracing capability absent from the H200's specification sheet. The 48.00 GPixel/s pixel rate, slightly ahead of the H200's 47.52 GPixel/s, shows that its modest 20 ROPs are sufficient for its target resolutions.

The NVIDIA H200 SXM 141 GB serves a completely different purpose. Its 700 W TDP, 8-pin EPS connector, 1100 W suggested PSU, and SXM Module form factor require a server infrastructure. The lack of display outputs and graphics API support confirms it is not intended for rendering. The 141 GB HBM3e pool, 4.89 TB/s bandwidth, 528 tensor cores, and 66.91 TFLOPS FP32 compute make it a compute accelerator for large-scale data processing. The 16896 shading units and 528 TMUs support massive parallel workloads, while the 24 ROPs keep pixel throughput in line with the Arc G3.

The release dates indicate product timing: the H200 appeared in 2024-11-17, and the Arc G3 follows on 2026-05-31. Both remain in Active production status. The H200's recorded predecessor and successor, Server Ada and Server Blackwell, show it sits within a defined server generation. The Arc G3's generation, Arc Graphics-M (Panther Lake), suggests a mobile-focused lineage.

The data gives no head-to-head benchmark scores, no average benchmark scores, and no rival comparisons, so any performance ranking must come from the specification deltas. Those deltas consistently favor the H200 in compute throughput, memory capacity, and bandwidth, while favoring the Arc G3 in clock boost potential, pixel rate, and power efficiency. The choice between them depends entirely on whether the requirement is integrated graphics or server compute. The database records no scenario where both would plausibly compete for the same deployment.
