AMD Instinct MI300X vs Intel Arc Graphics 64EU Mobile Comparison

Where Each One Wins

The AMD Instinct MI300X and Intel Arc Graphics 64EU Mobile occupy entirely different segments of the hardware spectrum, and the recorded data reflects this split clearly. The MI300X is a datacenter-oriented accelerator with a single Geekbench OpenCL entry of 317,994, placing it at the 100th percentile among all GPUs in the database. The Arc 64EU Mobile, by contrast, is an integrated graphics solution with no recorded benchmark scores, an average score of zero, and a percentile rank of 50.

The MI300X wins outright in every measurable compute category. It delivers 81.72 TFLOPS of FP32 performance and the same 81.72 TFLOPS in FP16 with a 1:1 ratio. The Arc 64EU Mobile manages 1.792 TFLOPS FP32 and 3.584 TFLOPS FP16, the latter at a 2:1 ratio. The MI300X also dominates memory: 192 GB of HBM3 on an 8192-bit bus with 5.32 TB/s bandwidth, versus the Arc's system-shared memory with system-dependent bandwidth. Texture rate favors the MI300X at 2,553.6 GTexel/s against 56.00 GTexel/s for the Arc, while pixel rate goes the other way, with the Arc producing 28.00 GPixel/s and the MI300X producing 0 MPixel/s.

The Arc 64EU Mobile wins in areas that reflect its intended role. It has display outputs (portable-device dependent), supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, and operates as an IGP with a 65 W TDP. The MI300X has no display outputs, no graphics API support, and consumes 750 W as an OAM module. The Arc is built for rendering to a screen; the MI300X is built for compute throughput. Their benchmark records confirm this: the MI300X has one score, the Arc has none, so the win tally in the database is 0 to 0, but that is because head-to-head benchmarks do not exist for this pairing.

Architecture Differences

The MI300X uses the CDNA 3.0 architecture on a 5 nm TSMC process, with the chip codenamed Aqua Vanjaram. It packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The Arc 64EU Mobile uses Intel's Xe-LPG architecture on a 10 nm Intel process, with the chip Meteor Lake, and the database records no transistor count, die size, or density for it. The process node gap alone explains much of the performance disparity: 5 nm versus 10 nm represents a major generational difference in density and efficiency.

The MI300X has 19,456 shading units and 1,216 texture mapping units, but zero ROPs and zero pixel rate. This is a compute accelerator, not a rasterizer. The Arc 64EU Mobile has 512 shading units, 32 TMUs, and 16 ROPs, which is a conventional integrated GPU layout. The MI300X's FP16 output equals its FP32 output at a 1:1 ratio, indicating a compute-oriented design that does not double-rate half-precision. The Arc doubles its FP16 throughput to 3.584 TFLOPS from 1.792 TFLOPS FP32, a 2:1 ratio that is typical for consumer graphics hardware.

Memory architecture could not be more different. The MI300X uses 192 GB of HBM3 across an 8192-bit bus, giving 5.32 TB/s of bandwidth. The Arc uses system-shared memory with a system-shared bus width and system-dependent bandwidth, meaning its memory performance depends entirely on the host laptop's RAM configuration. Clock behavior differs as well: the MI300X has a 1000 MHz base and 2100 MHz boost, with memory at 1300 MHz (5.2 Gbps effective). The Arc has a 300 MHz base and 1750 MHz boost, with no dedicated memory clock because it shares system memory.

The bus interfaces reflect their placements. The MI300X uses PCIe 5.0 x16, a full-bandwidth external connection. The Arc uses a Ring Bus, which ties it directly to the CPU die in the Meteor Lake package. Power delivery also diverges: the MI300X requires a 1150 W suggested PSU, draws 750 W, and has no power connectors (it uses an OAM module edge connector). The Arc is an IGP with a 65 W TDP and no separate power connector listed.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair, so direct comparisons must rely on the MI300X's single Geekbench OpenCL score and the Arc's absence of any recorded score. The MI300X scores 317,994, which places it at the 100th percentile among all GPUs. The Arc scores zero on average with no benchmark entries, placing it at the 50th percentile by default.

Looking at the MI300X's nearest rivals provides context for its score. The NVIDIA H200 NVL averages 334,891, which is 5% higher than the MI300X. The NVIDIA B200 averages 345,482, 8% higher. The MI300X sits between the NVIDIA L40S at 295,763 (7.5% lower) and the RTX 6000 Ada Generation at 287,237 (10.7% lower) on the low side, and the H200 NVL and B200 on the high side. This places the MI300X in the upper tier of datacenter accelerators, slightly behind the newest NVIDIA offerings but ahead of the L40S and RTX 6000 Ada by meaningful margins.

The Arc 64EU Mobile has no rivals listed and no scores, so its relative position is defined only by its percentile. At the 50th percentile, it sits exactly at the median of all GPUs in the database, which for an integrated part is a reasonable placement given that the database includes many older and lower-end discrete parts. The FP32 throughput difference is stark: the MI300X delivers 81.72 TFLOPS, which is roughly 45.6 times the Arc's 1.792 TFLOPS. FP16 shows a similar gap of about 22.8 times (81.72 versus 3.584). Texture rate is about 45.6 times higher on the MI300X as well, while the Arc's pixel rate advantage is infinite since the MI300X has zero ROPs.

Memory bandwidth tells the clearest story. The MI300X has 5.32 TB/s of dedicated HBM3 bandwidth. The Arc has system-dependent bandwidth, which in a typical mobile platform would be a fraction of that, but the database records no specific number. The MI300X also has 192 GB of on-package memory, while the Arc must share whatever system RAM the host provides.

The Verdict

The data indicates two products with no overlap in purpose. The AMD Instinct MI300X is a datacenter compute accelerator with 192 GB of HBM3, 81.72 TFLOPS FP32, and a Geekbench OpenCL score of 317,994. It is designed for massive parallel workloads, large model inference, and high-bandwidth memory access. Its 750 W TDP and OAM form factor require a server platform, and its lack of display outputs and graphics APIs makes it unsuitable for any rendering task.

The Intel Arc Graphics 64EU Mobile is an integrated GPU for laptops and portable devices. It has 512 shading units, 16 ROPs, a 65 W TDP, and supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. It drives displays through portable-device-dependent outputs. Its FP32 throughput of 1.792 TFLOPS is modest but appropriate for an IGP, and its 3.584 TFLOPS FP16 rate with 2:1 ratio indicates some compute flexibility for accelerated workloads.

Choosing between them is not a choice at all; the MI300X is for server racks and the Arc is for mobile systems. The MI300X's 100th percentile rank and its position relative to the NVIDIA H200 NVL, B200, L40S, and RTX 6000 Ada show it belongs in the top tier of accelerators. The Arc's 50th percentile rank with no scores shows it is an unremarkable integrated part, adequate for everyday graphics but not for heavy compute. The database records no head-to-head benchmarks because no reasonable test would pair them.
