AMD Instinct MI355X vs Intel Arc Graphics 32EU Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the AMD Instinct MI355X and the Intel Arc Graphics 32EU. This absence is itself informative. The two devices occupy entirely separate segments of the GPU landscape, and the available data reflects that divide. The AMD Instinct MI355X carries no benchmark entries at all, while the Intel Arc Graphics 32EU has a single recorded score in 3DMark Steel Nomad DX12 at 733 points.

That 733-point result places the Intel part at the 3rd percentile of all GPUs in the database. Its nearest recorded rivals include the Intel Arc Graphics 24EU at 733 points with a 0% delta, the Intel Arc Graphics 64EU also at 733 points with a 0% delta, the AMD Radeon HD 6470M at 723 points with a 1.4% delta, and the NVIDIA GeForce GT 415M at 751 points with a -2.4% delta. The data shows the Arc Graphics 32EU sits in a tight cluster of low-end parts, effectively tied with its 24EU and 64EU siblings in this particular test, marginally ahead of the Radeon HD 6470M, and slightly behind the GeForce GT 415M.

For the AMD Instinct MI355X, the absence of benchmark scores means there is no direct measurement to compare against the Intel part. The database records a 50th percentile position for the MI355X across all GPUs, which reflects a median standing in the overall distribution, though with an average benchmark score of zero, this percentile likely derives from its specifications rather than from any recorded test runs.

The specification gap between these two devices is enormous. The MI355X delivers 78.64 TFLOPS of FP32 compute, while the Arc Graphics 32EU delivers 998.4 GFLOPS. The ratio is roughly 79 to 1. In FP16, the MI355X produces 78.64 TFLOPS with a 1:1 ratio, while the Intel part produces 1.997 TFLOPS with a 2:1 ratio. Texture rate tells a similar story: 2,457.6 GTexel/s against 31.20 GTexel/s. Pixel rate shows a different kind of divergence, the MI355X records 0 MPixel/s, while the Intel part records 15.60 GPixel/s. This reflects the MI355X's design as a compute accelerator without traditional rasterization outputs.

The memory systems could hardly be more different. The MI355X has 288 GB of HBM3e on an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The Arc Graphics 32EU uses system shared memory, with a bus width listed as system shared and bandwidth described as system dependent. No fixed capacity, bus width, or bandwidth figure exists for the Intel part because it depends entirely on the host system's memory configuration.

Where Each One Wins

The benchmark data does not contain a single test where both devices appear, so a direct win-loss tally is impossible. The database records zero wins for each device in head-to-head comparisons. Instead, the strengths of each part must be inferred from their recorded specifications and the single benchmark score available.

The Intel Arc Graphics 32EU wins in the category of integrated graphics capability. It is an IGP with a 65 W TDP, designed to operate within a processor package using a Ring Bus interface. Its display outputs are motherboard dependent, meaning it can drive displays in systems where the motherboard provides the appropriate connectors. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This is a part that can render graphics for everyday use, and its recorded 733-point Steel Nomad score, while modest, confirms it can complete a modern DX12 workload.

The AMD Instinct MI355X wins decisively in raw compute throughput. Its FP32 figure of 78.64 TFLOPS is an order of magnitude beyond what any integrated graphics solution could approach. Its FP16 performance at the same 78.64 TFLOPS with a 1:1 ratio indicates the architecture does not sacrifice half-precision throughput, which matters for AI inference and training workloads that rely heavily on FP16. The 288 GB memory capacity with 8.19 TB/s bandwidth provides the kind of data feeding capability that large model training requires. The MI355X has no display outputs, which signals its purpose: it is not meant to show images on a screen but to process data at scale.

The MI355X also wins on process technology metrics. Both parts use a 3 nm process from TSMC, but the MI355X packs 185,000 million transistors into a 2380 mm² die, achieving a transistor density of 77.7M per mm². The Arc Graphics 32EU contains 17,800 million transistors on a 243 mm² die, with a density of 73.3M per mm². The MI355X die is nearly ten times larger and holds over ten times more transistors.

The thermal envelopes reflect their roles. The MI355X is rated at 1400 W TDP with a suggested PSU of 1800 W, and it uses an OAM module form factor. The Arc Graphics 32EU draws 65 W and has no suggested PSU listed, because it inherits power from the host processor's platform. The MI355X requires dedicated power infrastructure, while the Intel part needs none beyond what the motherboard provides.

Specification Differences

The two devices differ in nearly every measurable specification category. The MI355X uses the MI350 256CU chip, while the Arc Graphics 32EU uses the Arrow Lake-S chip. The MI355X is built on the CDNA 4.0 architecture, while the Intel part uses Xe-LPG. Both use a 3 nm TSMC process, but the transistor counts diverge sharply: 185,000 million for the MI355X versus 17,800 million for the Intel part. Die size measures 2380 mm² for the MI355X and 243 mm² for the Arc Graphics 32EU.

Clock speeds differ substantially. The MI355X has a 1000 MHz base clock and 2400 MHz boost clock. The Arc Graphics 32EU has a 300 MHz base clock and 1950 MHz boost clock. Memory clocks are not directly comparable: the MI355X runs at 2000 MHz with 8 Gbps effective, while the Intel part lists system shared memory.

Compute unit counts differ in kind. The MI355X has 16,384 shading units, 1,024 TMUs, and 0 ROPs. The Arc Graphics 32EU has 256 shading units, 16 TMUs, and 8 ROPs. This explains the pixel rate figures: 0 MPixel/s for the MI355X and 15.60 GPixel/s for the Intel part. Texture rates are 2,457.6 GTexel/s versus 31.20 GTexel/s.

Power and form factor differences are stark. The MI355X has a 1400 W TDP, requires an 1800 W suggested PSU, uses an OAM Module slot width, and lists no power connectors because OAM modules receive power through the carrier board. The Arc Graphics 32EU has a 65 W TDP, is an IGP, and uses a Ring Bus interface. The MI355X connects via PCIe 5.0 x16, while the Intel part has no PCIe interface listed.

The MI355X measures 102 mm in length and 165 mm in width. The Arc Graphics 32EU has no dimensions listed, consistent with its integrated nature. Release dates differ by roughly eight months: the Intel part launched on 2024-10-23, and the MI355X on 2025-06-11. The MI355X lists Radeon Instinct as its predecessor, while the Arc Graphics 32EU lists HD Graphics-M. The Intel part is marked as active in production status; the MI355X has no production status recorded. Neither device has a launch MSRP in the database.

Architecture Differences

The MI355X uses CDNA 4.0, AMD's compute-focused architecture, built around the MI350 256CU chip with 256 compute units. The Intel Arc Graphics 32EU uses Xe-LPG, a graphics-oriented architecture derived from Intel's Arc family, implemented in the Arrow Lake-S processor. The names alone indicate divergent priorities: CDNA stands for Compute DataNova Architecture, while Xe-LPG belongs to Intel's Xe graphics lineage.

Transistor density offers a subtle architectural comparison. The MI355X achieves 77.7M transistors per mm², and the Arc Graphics 32EU achieves 73.3M per mm². The densities are similar, which makes sense given both use TSMC's 3 nm process. The difference in total transistor count, 185,000 million versus 17,800 million, comes almost entirely from die size rather than density. The MI355X simply has far more silicon area to work with.

Memory architecture differs fundamentally. The MI355X uses 288 GB of HBM3e stacked memory on an 8192-bit bus, a configuration designed for massive bandwidth in data center workloads. The Arc Graphics 32EU has no dedicated memory at all; it shares system memory with the host CPU, making its bandwidth dependent on the platform's memory subsystem. This is the defining architectural split between a discrete accelerator and an integrated GPU.

The MI355X lists no RT cores and no tensor cores, relying instead on its massive shading unit count and CDNA 4.0's compute pipelines. The Arc Graphics 32EU also lists no RT cores and no tensor cores, but it supports DirectX 12 Ultimate, which implies hardware features for modern graphics APIs. The MI355X lists N/A for DirectX, OpenGL, and Vulkan, indicating its driver stack targets compute frameworks rather than graphics APIs.

FP16 behavior reveals architectural differences in precision handling. The MI355X achieves 78.64 TFLOPS in FP16 with a 1:1 ratio to FP32, meaning it does not double throughput in half precision. The Arc Graphics 32EU achieves 1.997 TFLOPS in FP16 with a 2:1 ratio, meaning it processes half-precision data at twice its FP32 rate. These ratios reflect different design philosophies: the MI355X treats FP16 as equal to FP32, while the Intel part accelerates FP16 relative to FP32.

The MI355X's 0 ROPs and 0 MPixel/s pixel rate confirm it has no rasterization pipeline. The Arc Graphics 32EU's 8 ROPs and 15.60 GPixel/s pixel rate confirm it does. The Intel part also provides display outputs, motherboard dependent, while the MI355X provides none. The MI355X is a compute engine, not a graphics card.

The Verdict

The recorded data presents two devices with almost no overlap in purpose. The AMD Instinct MI355X is a 1400 W OAM module with 288 GB of HBM3e, 78.64 TFLOPS of FP32, and no display outputs. The Intel Arc Graphics 32EU is a 65 W integrated GPU with system shared memory, 998.4 GFLOPS of FP32, and motherboard-dependent display support. Any user choosing between them is not comparing two graphics cards but two different classes of hardware.

The MI355X is the choice for compute workloads that demand massive memory bandwidth and FP32 throughput. Its 8.19 TB/s bandwidth and 288 GB capacity support large datasets that would never fit in the memory subsystem of an integrated GPU. Its 78.64 TFLOPS of FP32 and matching FP16 throughput provide the kind of compute density expected in data center accelerators. The absence of display outputs and graphics API support does not matter for such workloads.

The Arc Graphics 32EU is the choice for a system that needs basic graphics output and modest compute capability within a constrained power envelope. Its 733-point Steel Nomad score places it in the lowest percentile tier of the database, but it can render graphics, drive displays, and complete modern DX12 workloads. Its 65 W TDP means it draws less than 5% of the MI355X's 1400 W power budget.

The data does not support a single recommendation for all users. The MI355X's 79-fold advantage in FP32 throughput and its 288 GB memory capacity are decisive for compute tasks. The Arc Graphics 32EU's display outputs, graphics API support, and integrated form factor are decisive for desktop graphics tasks. The MI355X sits at the 50th percentile of all GPUs in the database, while the Arc Graphics 32EU sits at the 3rd percentile, but that comparison reflects the database's inclusion of both compute accelerators and consumer graphics parts in a single distribution. The percentile figures do not change the fundamental conclusion: these devices serve different markets, and the recorded specifications make that distinction unambiguous.
