Intel Arc Graphics 32EU vs NVIDIA Rubin GPU Comparison

Where Each One Wins

The recorded data presents an unusual comparison: the Intel Arc Graphics 32EU has a single measurable benchmark result, while the NVIDIA Rubin GPU has no recorded benchmarks at all. This makes a conventional win/loss split impossible. Instead, the database shows each part winning in entirely different domains.

The Intel Arc Graphics 32EU is an integrated graphics processor built for the Arrow Lake-S desktop platform. Its only recorded benchmark, 3DMark Steel Nomad DX12, returns a score of 733 points. That places it in the 3rd percentile of all GPUs in the database, meaning 97% of recorded graphics processors score higher. Its nearest rivals in the database are the Intel Arc Graphics 24EU at 733 points (0% delta), the Intel Arc Graphics 64EU also at 733 points (0% delta), and the AMD Radeon HD 6470M at 723 points (1.4% slower). The NVIDIA GeForce GT 415M scores 751 points, which is 2.4% ahead. The data shows the 32EU model sits in a cluster of entries clustered tightly around the 723 to 751 point range. This is a low-end integrated solution by database standards, but it does have a measurable result.

The NVIDIA Rubin GPU takes the opposite approach. It is a server-class accelerator with 288 GB of HBM4 memory, 22.1 TB/s of bandwidth, and a 16384-bit memory bus. It has no benchmark entries in the database, so its percentile rank of 50 is a default placeholder rather than a measured outcome. The Rubin GPU wins in every architectural category where data exists, but it has no performance numbers to compare directly. The Intel part wins in the only category where a benchmark score exists: measurable 3D graphics performance in a consumer workload.

The use-case split is clear from the specifications. The Intel Arc Graphics 32EU is designed for systems where the CPU package provides graphics output. It has a 65 W TDP, uses the Ring Bus interface, and relies on system shared memory. The NVIDIA Rubin GPU is a 2300 W SXM module with no display outputs, a PCIe 6.0 x16 interface, and a suggested power supply of 2700 W. One is an IGP for everyday desktop use; the other is a compute accelerator for servers. The database shows no overlap in their intended workloads, and benchmark results only exist for one of them.

Architecture Differences

The two chips come from different design philosophies. The Intel Arc Graphics 32EU uses the Xe-LPG architecture, built on TSMC's 3 nm process. The chip is part of the Arrow Lake-S die, which contains 17,800 million transistors across a 243 mm² die. That yields a transistor density of 73.3 million transistors per square millimeter. The NVIDIA Rubin GPU uses the Rubin architecture on the same 3 nm TSMC process, but the GR100 chip packs 336,000 million transistors into a 1456 mm² die. Its transistor density is 230.8 million per square millimeter, roughly three times denser by the database's calculation.

The execution resources differ by orders of magnitude. The Intel part has 256 shading units, 16 texture mapping units, and 8 raster output pipelines. It has no dedicated ray tracing cores and no tensor cores listed. The NVIDIA part has 28,672 shading units, 896 texture mapping units, 24 ROPs, and 896 tensor cores. The Rubin GPU also lists no dedicated RT core count, but its tensor core count of 896 is substantial.

Clock behavior differs as well. The Intel IGP runs at a base clock of 300 MHz and boosts to 1950 MHz. The Rubin GPU runs at a 700 MHz base and boosts to 2267 MHz. Despite the lower base clock, the Rubin part's massive shader count produces far higher throughput. The pixel rate for Intel is 15.60 GPixel/s versus 54.41 GPixel/s for NVIDIA. Texture rate is 31.20 GTexel/s versus 2,031.2 GTexel/s. FP32 compute is 998.4 GFLOPS versus 130.0 TFLOPS. FP16 performance is 1.997 TFLOPS versus 260.0 TFLOPS, both listed with a 2:1 ratio.

Memory architecture is fundamentally different. The Intel part uses system shared memory with a system dependent bandwidth, meaning its performance scales with the host platform's memory configuration. The NVIDIA part has dedicated 288 GB of HBM4 memory on a 16384-bit bus, delivering 22.1 TB/s of bandwidth at an effective 10.8 Gbps data rate. The Intel part has no dedicated memory clock; the Rubin GPU's memory runs at 2695 MHz base with 10.8 Gbps effective throughput.

API support also diverges. Intel lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. NVIDIA lists N/A for DirectX, OpenGL, and Vulkan, which reflects its server orientation where compute APIs dominate. The Intel part has display outputs described as motherboard dependent, while the Rubin GPU has no outputs at all. Power requirements reflect the gap: 65 W TDP for the Intel IGP versus 2300 W for the SXM module, with a 2700 W suggested power supply.

Specification Differences

The two GPUs differ in nearly every recorded specification. The Intel Arc Graphics 32EU uses the Xe-LPG architecture on the Arrow Lake-S chip, while the NVIDIA Rubin GPU uses the Rubin architecture on the GR100 chip. The Intel generation is listed as Arc Graphics-M (Arrow Lake), the NVIDIA generation as Server Rubin (Rxx). The Intel part's process node is 3 nm from TSMC, and the Rubin GPU is also 3 nm from TSMC, but the die sizes diverge sharply: 243 mm² versus 1456 mm². Transistor counts are 17,800 million versus 336,000 million, with densities of 73.3M / mm² versus 230.8M / mm².

Clock speeds differ across the board. The Intel base clock is 300 MHz versus 700 MHz. Boost clocks are 1950 MHz versus 2267 MHz. The Intel memory clock is system shared, while the Rubin GPU runs at 2695 MHz with 10.8 Gbps effective. Memory size is system shared versus 288 GB. Memory type is system shared versus HBM4. Bus width is system shared versus 16384 bit. Bandwidth is system dependent versus 22.1 TB/s.

Compute resources show the largest gap. Shading units are 256 versus 28,672. TMUs are 16 versus 896. ROPs are 8 versus 24. Tensor cores are not listed for Intel but are 896 for NVIDIA. Pixel rate is 15.60 GPixel/s versus 54.41 GPixel/s. Texture rate is 31.20 GTexel/s versus 2,031.2 GTexel/s. FP32 is 998.4 GFLOPS versus 130.0 TFLOPS. FP16 is 1.997 TFLOPS versus 260.0 TFLOPS.

Form factor and power also differ. The Intel part is an IGP with a 65 W TDP and Ring Bus interface. The NVIDIA part is an SXM Module with a 2300 W TDP, a PCIe 6.0 x16 interface, and a suggested PSU of 2700 W. Display outputs are motherboard dependent for Intel and absent for NVIDIA. API support shows DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 for Intel, with N/A for all three on NVIDIA. Release dates are 2024-10-23 for Intel and 2025-12-31 for NVIDIA. The Intel predecessor is HD Graphics-M; the NVIDIA predecessor is Server Blackwell. Neither has a successor listed.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two GPUs. The Intel Arc Graphics 32EU has one benchmark: 3DMark Steel Nomad DX12 at 733 points. The NVIDIA Rubin GPU has an empty benchmark array. The winsA and winsB fields are both 0, confirming no direct comparison data exists.

The closest the database comes to a head-to-head is the Intel part's nearest rivals list. The Intel Arc Graphics 24EU and 64EU both match at 733 points with a 0% delta. The AMD Radeon HD 6470M trails by 1.4% at 723 points. The NVIDIA GeForce GT 415M leads by 2.4% at 751 points. These numbers place the 32EU model in a narrow performance band where integrated graphics from Intel and legacy discrete mobile parts converge.

For the NVIDIA Rubin GPU, the absence of benchmark data means the analysis must rely on specifications. Its FP32 throughput of 130.0 TFLOPS is roughly 130 times the Intel part's 998.4 GFLOPS. Its texture rate of 2,031.2 GTexel/s is over 65 times higher. Memory bandwidth of 22.1 TB/s versus system dependent bandwidth is not directly comparable, but the dedicated HBM4 configuration clearly exceeds any shared memory setup. The pixel rate of 54.41 GPixel/s is about 3.5 times the Intel part's 15.60 GPixel/s.

The Rubin GPU's 896 tensor cores and 288 GB memory capacity further separate it from the Intel IGP, which lists no tensor cores and relies on system memory. These are not competing products in any conventional sense. The data shows one part with a consumer graphics benchmark and the other with none, one at 3rd percentile and one at a default 50th percentile, one at 65 W and one at 2300 W.

The Verdict

The database presents two products with almost no common ground. The Intel Arc Graphics 32EU is a low-power integrated GPU for Arrow Lake-S desktop processors. Its 733 point 3DMark Steel Nomad DX12 score places it at the 3rd percentile, surrounded by other low-end parts: the Arc 24EU and 64EU at identical scores, the Radeon HD 6470M slightly behind, and the GeForce GT 415M slightly ahead. Any user of this IGP should expect entry-level 3D performance, consistent with its 256 shading units, 65 W TDP, and shared memory architecture.

The NVIDIA Rubin GPU is a server accelerator with no consumer graphics benchmarks recorded. Its 288 GB HBM4 memory, 22.1 TB/s bandwidth, 28,672 shading units, and 896 tensor cores point to compute and AI workloads, not rasterization. The 2300 W TDP and SXM module form factor confirm its data center orientation. The lack of display outputs and N/A API entries for DirectX, OpenGL, and Vulkan reinforce this.

Who should pick which, strictly from the data? A system builder using an Arrow Lake-S processor with integrated graphics needs the Intel Arc Graphics 32EU for display output and basic 3D workloads. It has a measurable benchmark result, active production status, and a 2024 release date. A server operator needing massive memory bandwidth and tensor throughput would select the NVIDIA Rubin GPU, despite having no benchmark results to validate performance. The data shows the Rubin GPU's superiority in every specification category, but the Intel part is the only one with a verified graphics score. The choice depends entirely on whether the requirement is integrated desktop graphics or server compute acceleration. There is no overlap in their recorded capabilities.
