AMD Instinct MI350P vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark runs for the AMD Instinct MI350P and the Intel Arc G3 Extreme. Both products register an average benchmark score of 0 and a percentile rank of 50 against all GPUs in the database. This absence of measured performance data means any direct numerical comparison of frame rates, compute throughput, or application scores is not possible from recorded measurements.

What the data does show is a stark contrast in raw specification limits. The AMD Instinct MI350P delivers 36.04 TFLOPS of FP32 compute and 36.04 TFLOPS of FP16 compute with a 1:1 ratio. The Intel Arc G3 Extreme delivers 7.680 TFLOPS of FP32 and 15.36 TFLOPS of FP16 with a 2:1 ratio. In raw FP32 throughput, the MI350P is 4.69 times higher than the Arc G3 Extreme. In FP16 throughput, the MI350P is 2.35 times higher.

Texture and pixel throughput also diverge sharply. The MI350P records a texture rate of 1,126.4 GTexel/s, which is 9.39 times the Arc G3 Extreme's 120.0 GTexel/s. The Arc G3 Extreme counters with a pixel rate of 60.00 GPixel/s, while the MI350P records 0 MPixel/s, a consequence of its absence of ROPs. The MI350P has no ROP units listed, whereas the Arc G3 Extreme has 24 ROPs.

Memory capacity and bandwidth are equally lopsided. The MI350P uses 144 GB of HBM3e across an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The Arc G3 Extreme relies on system shared memory with bus width, capacity, and bandwidth all marked as system dependent. The MI350P's memory bandwidth exceeds any system-shared configuration the database records for the Intel part.

Clock behavior also differs. The MI350P operates at a base clock of 1000 MHz and boosts to 2200 MHz. The Arc G3 Extreme has a base of 300 MHz and boosts to 2500 MHz. The Intel part has a higher boost ceiling by 300 MHz, but its base clock is 700 MHz lower. The MI350P's memory clock is 2000 MHz with 8 Gbps effective, while the Arc G3 Extreme's memory clock is listed simply as system shared.

Where Each One Wins

The AMD Instinct MI350P wins decisively in compute-heavy workloads that depend on FP32 or FP16 throughput. Its 8192 shading units, 512 texture mapping units, and 36.04 TFLOPS in both FP32 and FP16 make it suited for large-scale parallel computation. The 8.19 TB/s memory bandwidth and 144 GB capacity provide the data feeding rates required for sustained compute tasks. The MI350P also has a 3 nm process node from TSMC, which supports its 73,000 million transistor count on a 1190 mm² die.

The Intel Arc G3 Extreme wins in scenarios where power consumption and physical footprint matter. Its 80 W TDP is far below the MI350P's 600 W. It is an integrated graphics processor (IGP) with no power connectors and no dedicated slot width, meaning it occupies no expansion slot. The Arc G3 Extreme also supports modern graphics APIs: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI350P records N/A for DirectX, OpenGL, and Vulkan. The Intel part has 12 ray tracing cores and 24 ROPs, enabling graphics rendering and ray-traced workloads that the MI350P cannot handle due to its lack of display outputs and graphics API support.

The Arc G3 Extreme also posts a higher boost clock at 2500 MHz versus 2200 MHz, and its FP16 performance of 15.36 TFLOPS is double its FP32 figure, indicating a design that favors mixed-precision workloads. The MI350P's 1:1 FP16 to FP32 ratio suggests no such acceleration for half-precision tasks.

Architecture Differences

The AMD Instinct MI350P uses CDNA 4.0 architecture on a 3 nm TSMC process. Its chip is designated MI350 128CU, and it belongs to the Instinct (MIx) generation. The die size is 1190 mm² with 73,000 million transistors, resulting in a transistor density of 61.3M per mm². The Intel Arc G3 Extreme uses Xe3-LPG architecture on a 3 nm Intel process. Its chip is Panther Lake, and it belongs to the Arc Graphics-M (Panther Lake) generation. The Intel part's transistor count and die size are unknown in the database.

Core configuration differs fundamentally. The MI350P has 8192 shading units, 512 TMUs, and 0 ROPs. The Arc G3 Extreme has 1536 shading units, 48 TMUs, and 24 ROPs. The MI350P has no ray tracing cores listed, while the Arc G3 Extreme has 12. The MI350P has no tensor cores listed; the Arc G3 Extreme also lists none.

Memory architecture is a major divergence. The MI350P uses dedicated HBM3e memory: 144 GB, 8192-bit bus, 8.19 TB/s bandwidth. The Arc G3 Extreme uses system shared memory, with all memory fields marked as system dependent. This means the Intel part's memory performance is tied to the host system's RAM configuration, not a fixed specification.

Power delivery and physical design differ completely. The MI350P is a dual-slot card, 267 mm long, 111 mm tall, and 40 mm wide, with a single 16-pin power connector and a suggested 1000 W PSU. It has no display outputs. The Arc G3 Extreme is an IGP with no slot width, no dimensions recorded, no power connectors, and display outputs marked as portable device dependent.

API support separates the two decisively. The MI350P records N/A for DirectX, OpenGL, and Vulkan. The Arc G3 Extreme supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface also differs: PCIe 5.0 x16 for the MI350P, IGP for the Arc G3 Extreme.

Release dates are close: the MI350P launched on 2026-05-06, and the Arc G3 Extreme on 2026-05-31. The MI350P's predecessor is Radeon Instinct, while the Arc G3 Extreme has no predecessor listed. Production status for the MI350P is null, while the Arc G3 Extreme is marked active.

The Verdict

The AMD Instinct MI350P is the choice for compute applications that demand maximum FP32 or FP16 throughput, large memory capacity, and extreme bandwidth. Its 36.04 TFLOPS in both precisions, 144 GB HBM3e, and 8.19 TB/s bandwidth position it as a dedicated accelerator for data-center-scale workloads. The absence of graphics APIs, ROPs, and display outputs confirms it is not a rendering product. Its 600 W TDP and dual-slot footprint require a server platform, as reflected in the suggested 1000 W PSU.

The Intel Arc G3 Extreme is the choice for portable or integrated systems where graphics capability, low power draw, and API support are required. Its 80 W TDP, IGP form factor, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 make it a functional graphics solution for devices with shared memory. Its 12 ray tracing cores and 60.00 GPixel/s pixel rate enable rendering tasks the MI350P cannot perform. The higher boost clock of 2500 MHz partially compensates for its lower core count.

The data does not provide a single winner because the two products target mutually exclusive use cases. The MI350P wins every compute and memory metric by margins ranging from 2.35 times in FP16 to 9.39 times in texture rate. The Arc G3 Extreme wins every graphics and integration metric: it has ROPs, ray tracing cores, API support, display outputs, and a fraction of the power requirement. Any selection between them depends entirely on whether the workload is compute acceleration or graphics rendering.
