Intel Arc Graphics 4 Xe Mobile vs NVIDIA H800 SXM5 Comparison

Intel Arc Graphics 4 Xe Mobile and NVIDIA H800 SXM5 occupy opposite ends of the GPU spectrum. The Intel part is a 25 W integrated solution for Panther Lake laptops, while the NVIDIA part is a 700 W server accelerator built on the GH100 chip. The recorded data shows no shared benchmark suite, so the comparison relies on architectural specifications and measured throughput limits.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmarks between these two parts. Instead, the comparison must be drawn from peak throughput figures and physical specifications. The NVIDIA H800 SXM5 delivers 59.30 TFLOPS of FP32 compute, which is 25.2 times the 2.355 TFLOPS of the Intel Arc Graphics 4 Xe Mobile. That gap is the defining feature of this matchup.

In FP16 workloads, the divergence widens further. The H800 SXM5 reaches 237.2 TFLOPS using a 4:1 ratio, while the Intel part manages 4.710 TFLOPS at a 2:1 ratio. The NVIDIA accelerator is 50.4 times faster in this metric, a difference that reflects both the much larger silicon and the specialized tensor hardware.

Texture throughput shows a similar story. The H800 SXM5 processes 926.6 GTexel/s, while the Intel iGPU reaches 73.60 GTexel/s. That is a 12.6 times advantage for the server part. Pixel throughput is closer: the NVIDIA card outputs 42.12 GPixel/s versus 36.80 GPixel/s for Intel, a modest 1.14 times lead. The Intel part's higher boost clock of 2300 MHz compared to 1755 MHz helps close the pixel gap despite having only 16 ROPs.

The H800 SXM5 has 528 tensor cores, while the Intel Arc Graphics 4 Xe Mobile has none listed. In any workload that relies on tensor operations, the NVIDIA part operates in a different class entirely. The Intel iGPU counters with 4 ray tracing cores, a feature absent from the H800 SXM5's specification sheet.

Where Each One Wins

The Intel Arc Graphics 4 Xe Mobile wins in power efficiency and physical integration. Its 25 W TDP fits into a mobile platform with no power connectors and no separate slot. The H800 SXM5 requires 700 W, an 8-pin EPS connector, and a suggested PSU of 1100 W. The Intel part also supports display outputs, though they are portable device dependent, while the NVIDIA card lists no outputs.

The H800 SXM5 dominates in raw compute and memory bandwidth. Its 80 GB of HBM3 memory across a 5120 bit bus delivers 3.36 TB/s, while the Intel iGPU shares system memory with bandwidth described as system dependent. For large data sets and high throughput workloads, the NVIDIA part has no competition in this pairing.

The Intel part wins on API support. It lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H800 SXM5 lists no DirectX, OpenGL, or Vulkan versions, reflecting its server-focused design with no display or consumer graphics API requirements.

Clock behavior favors Intel in boost frequency. The Arc Graphics 4 Xe Mobile boosts to 2300 MHz from a 300 MHz base, a wide dynamic range suited to power management in thin laptops. The H800 SXM5 runs at 1095 MHz base and 1755 MHz boost, a narrower range typical of high-power accelerators.

Architecture Differences

The Intel Arc Graphics 4 Xe Mobile uses the Xe3-LPG architecture on Panther Lake silicon, built on Intel's 3 nm process. The NVIDIA H800 SXM5 uses the Hopper architecture with the GH100 chip, fabricated by TSMC on a 5 nm node. The transistor counts reflect the scale difference: the H800 SXM5 contains 80,000 million transistors on an 814 mm² die, while Intel lists the transistor count as unknown.

The H800 SXM5 has a transistor density of 98.3M per mm². The Intel part does not list die size or transistor density, so no direct density comparison is possible from the recorded data.

Compute resources differ by an order of magnitude. The NVIDIA part has 16896 shading units, 528 TMUs, and 24 ROPs. The Intel iGPU has 512 shading units, 32 TMUs, and 16 ROPs. The H800 SXM5 adds 528 tensor cores, while the Intel part instead carries 4 ray tracing cores.

Memory architecture separates the two completely. The H800 SXM5 uses 80 GB of HBM3 on a 5120 bit bus with 3.36 TB/s bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system shared memory with system dependent bandwidth, meaning its performance scales with the host platform's memory configuration.

The H800 SXM5 connects via PCIe 5.0 x16, while the Intel part uses an integrated graphics processor bus interface. The NVIDIA card is an SXM module, the Intel part is an IGP. Power delivery matches their positions: the H800 SXM5 draws 700 W and needs an 8-pin EPS connector, the Intel part draws 25 W with no power connectors at all.

Production status is active for both. The Intel part has a release date of 2026-01-26, while the H800 SXM5 dates to 2023-03-20. The NVIDIA card has a predecessor listed as Server Ada and a successor as Server Blackwell. The Intel part lists no predecessor or successor.

The Verdict

The data supports a straightforward split. The NVIDIA H800 SXM5 is for compute-heavy server workloads where 59.30 TFLOPS FP32, 237.2 TFLOPS FP16, 80 GB HBM3, and 3.36 TB/s bandwidth matter more than power draw or size. The Intel Arc Graphics 4 Xe Mobile is for mobile systems where 25 W power draw, integrated packaging, and display output support are the priorities. The H800 SXM5 wins on raw throughput by factors of 25 to 50 depending on the workload. The Intel part wins on integration, API coverage, and power efficiency. Choosing between them depends entirely on the target platform and workload type, not on any single benchmark result.
