Intel Iris Xe Graphics 80EU Mobile vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for these two processors. The database shows zero wins for either side, and no competitive benchmark scores are available for comparison. This absence of measured performance data means the analysis must rely entirely on the specification sheets and architectural parameters recorded in the database.

The Intel Iris Xe Graphics 80EU Mobile delivers a FP32 throughput of 1.856 TFLOPS and a FP16 throughput of 3.712 TFLOPS (2:1). The NVIDIA H20 delivers a FP32 throughput of 39.54 TFLOPS and a FP16 throughput of 79.07 TFLOPS (2:1). The raw compute gap is substantial: the H20 offers approximately 21.3 times the FP32 throughput and approximately 21.3 times the FP16 throughput of the Iris Xe part. These figures come directly from the recorded specifications, and they define the performance envelope for any workload that scales with floating-point operations.

Texture and pixel processing rates follow a similar pattern. The Iris Xe Graphics 80EU Mobile records a texture rate of 58.00 GTexel/s and a pixel rate of 29.00 GPixel/s. The NVIDIA H20 records a texture rate of 617.8 GTexel/s and a pixel rate of 47.52 GPixel/s. The H20 is approximately 10.7 times faster in texture fill and approximately 1.6 times faster in pixel fill. The smaller pixel-rate advantage relative to the compute advantage reflects the H20's architecture, which prioritizes compute and memory bandwidth over traditional rasterization throughput.

Memory bandwidth is another decisive separator. The Iris Xe Graphics 80EU Mobile uses system-shared memory with bandwidth described as "System Dependent." The NVIDIA H20 uses 96 GB of HBM3 memory on a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The H20's memory subsystem is designed for data-center workloads where large datasets must be streamed to the compute units. The Iris Xe part has no dedicated memory bandwidth figure because it depends entirely on the host system's memory configuration.

Clock behavior also differs. The Iris Xe Graphics 80EU Mobile has a base clock of 300 MHz and a boost clock of 1450 MHz. The NVIDIA H20 has a base clock of 1830 MHz and a boost clock of 1980 MHz. The H20's boost clock is approximately 36.6% higher than the Iris Xe's boost clock, but the compute advantage is far larger because the H20 also has many more shader units.

The shading unit count tells the story. The Iris Xe Graphics 80EU Mobile has 640 shading units, 40 TMUs, and 20 ROPs. The NVIDIA H20 has 9984 shading units, 312 TMUs, and 24 ROPs. The H20 has approximately 15.6 times the shading units and 7.8 times the TMUs, while the ROP count is only 1.2 times higher. This allocation confirms that the H20 is built for massively parallel compute rather than traditional graphics rendering.

The Verdict

The database indicates that these are fundamentally different classes of processors. The Intel Iris Xe Graphics 80EU Mobile is an integrated graphics processor within the Raptor Lake generation, built on Intel's 10 nm process. It consumes 15 W, uses system-shared memory, and is classified as an IGP with a Ring Bus interface. It was released on 2023-01-03 and remains in active production, with its successor listed as Arc Graphics-M.

The NVIDIA H20 is a server-grade accelerator from the Hopper architecture, built on TSMC's 5 nm process. It consumes 500 W, uses 96 GB of HBM3 memory, and is classified as an SXM Module with a PCIe 5.0 x16 bus interface. It was released on 2024-01-31 and remains in active production, with its predecessor listed as Server Ada and its successor listed as Server Blackwell.

The data shows no benchmark results for either product, so no direct performance ranking can be established from measured workloads. However, the specification sheets indicate that the H20 is designed for server environments where compute throughput, memory capacity, and memory bandwidth are the primary requirements. The Iris Xe Graphics 80EU Mobile is designed for mobile platforms where power draw and integration matter more than raw throughput.

The percentile versus all GPUs is recorded as 50 for both products, which places both at the median of the database's GPU population. This is a relative ranking based on the database's overall distribution, not a comparison between these two specific parts.

Architecture Differences

The Intel Iris Xe Graphics 80EU Mobile uses the Generation 12.2 architecture from Intel, implemented on a 10 nm process node. The chip is identified as Raptor Lake, and the generation is listed as HD Graphics-M (Raptor Lake). The foundry is Intel. No transistor count, die size, or transistor density figures are recorded for this part.

The NVIDIA H20 uses the Hopper architecture from NVIDIA, implemented on a 5 nm process node from TSMC. The chip is identified as GH100. The generation is listed as Server Hopper (Hxx). The database records 80,000 million transistors, a die size of 814 mm², and a transistor density of 98.3M / mm².

The Iris Xe part has no dedicated tensor cores, while the H20 has 312 tensor cores. This is a significant architectural divergence: the H20 includes tensor-core hardware for matrix operations, while the Iris Xe part relies solely on its shading units. Neither part records ray-tracing cores.

The memory architecture is entirely different. The Iris Xe Graphics 80EU Mobile uses system-shared memory with a system-shared bus width and system-dependent bandwidth. The H20 uses 96 GB of HBM3 memory on a 6144-bit bus with a fixed bandwidth of 4.03 TB/s. The memory clock for the H20 is recorded as 1313 MHz with 5.3 Gbps effective data rate.

API support also differs. The Iris Xe Graphics 80EU Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA H20 records N/A for DirectX, OpenGL, and Vulkan. This reflects the H20's server orientation, which does not require traditional graphics API support.

The display outputs differ as well. The Iris Xe part has display outputs described as "Portable Device Dependent," while the H20 has no outputs. The Iris Xe part is an IGP with a Ring Bus interface, and the H20 is an SXM Module with a PCIe 5.0 x16 interface.

Where Each One Wins

The Intel Iris Xe Graphics 80EU Mobile wins in the categories of power efficiency and platform integration. Its 15 W power draw is a fraction of the H20's 500 W, making it suitable for mobile devices where thermal and power budgets are tight. The Iris Xe part also provides display outputs, while the H20 has none. The Iris Xe part supports traditional graphics APIs, including DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, which makes it usable for graphics rendering workloads on portable systems. The Ring Bus interface and IGP form factor mean it can operate within a laptop or compact device without a separate expansion slot.

The NVIDIA H20 wins in raw compute throughput, memory capacity, and memory bandwidth. Its FP32 throughput of 39.54 TFLOPS and FP16 throughput of 79.07 TFLOPS are overwhelmingly higher than the Iris Xe part's 1.856 TFLOPS and 3.712 TFLOPS. The H20's 96 GB of HBM3 memory with 4.03 TB/s of bandwidth provides a memory subsystem that can feed its 9984 shading units and 312 tensor cores. The H20 records a texture rate of 617.8 GTexel/s, which is approximately 10.7 times the Iris Xe part's 58.00 GTexel/s. The H20's pixel rate of 47.52 GPixel/s is approximately 1.6 times the Iris Xe part's 29.00 GPixel/s.

The H20 also has a higher base clock (1830 MHz versus 300 MHz) and boost clock (1980 MHz versus 1450 MHz). Its 312 tensor cores provide hardware acceleration for matrix operations, a feature entirely absent from the Iris Xe part. The H20 is built on a 5 nm TSMC process with 80,000 million transistors on an 814 mm² die, while the Iris Xe part uses Intel's 10 nm process with no transistor count recorded.
