AMD Instinct MI325X vs Intel Arc Graphics 48EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is unusual: neither part has any benchmark entries in the database, and the head-to-head benchmark array is empty. Both GPUs share an identical percentile rank of 50 against all GPUs, and both carry an average benchmark score of zero. This means the database contains no measured performance results for either the AMD Instinct MI325X or the Intel Arc Graphics 48EU Mobile, and there are no direct comparison scores to reference.

Because no benchmark scores exist, there are no exact win margins, no delta percentages, and no rival comparisons to cite. The only numerical performance indicators available are the theoretical specifications listed in each part’s profile. The AMD Instinct MI325X lists 81.72 TFLOPS for FP32 and FP16 (at a 1:1 ratio), while the Intel Arc Graphics 48EU Mobile lists 1,382.4 GFLOPS for FP32 and 2.765 TFLOPS for FP16 (at a 2:1 ratio). Converting both to the same unit, the MI325X’s FP32 figure is 81,720 GFLOPS, which is roughly 59 times higher than the Intel part’s FP32 figure. For FP16, the MI325X’s 81.72 TFLOPS is about 29.5 times higher than the Arc part’s 2.765 TFLOPS.

These are raw throughput limits from the specification sheets, not measured outcomes. The database shows no evidence of real-world application tests, synthetic runs, or game frame captures for either product. In the absence of benchmark data, the only defensible statements are about what each chip is architecturally capable of, not what it actually delivers in a workload.

Where Each One Wins

Without benchmark results, the wins must be inferred from the specification differences. The AMD Instinct MI325X is designed as a data center accelerator module with an OAM slot width, no display outputs, and a 1000 W TDP. Its memory configuration is fixed at 256 GB of HBM3e across an 8192-bit bus, delivering 6.14 TB/s of bandwidth. The Intel Arc Graphics 48EU Mobile is an integrated graphics processor with a 28 W TDP, system-shared memory, and portable-device-dependent display outputs. These are fundamentally different product categories.

The MI325X wins on every throughput metric that can be derived from its spec sheet: FP32, FP16, texture rate (2,553.6 GTexel/s versus 43.20 GTexel/s), and memory bandwidth. Its pixel rate is listed as 0 MPixel/s, which matches the absence of any ROPs (0 ROPs) and its lack of display outputs. The Intel part has 8 ROPs and a pixel rate of 14.40 GPixel/s, so it wins the pixel throughput category, though that is irrelevant for a compute accelerator with no display path.

The Arc Graphics 48EU Mobile wins on power efficiency in a strict sense: it operates at 28 W versus 1000 W, a 35.7x difference in TDP, while offering a fraction of the compute throughput. The data does not include efficiency ratios, so no exact efficiency figure can be stated. The Intel part also wins on portability: it is an IGP with system-dependent memory, meaning it fits into laptops and small form factor devices, while the MI325X is a standalone module that requires a host system with PCIe 5.0 x16 and a 1400 W suggested PSU.

Architecture Differences

The AMD Instinct MI325X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The chip has 19,456 shading units, 1,216 texture mapping units, and zero ROPs. It uses HBM3e memory with a 256 GB capacity and an 8192-bit bus. The base clock is 1000 MHz with a boost clock of 2100 MHz, and memory runs at 1500 MHz (6 Gbps effective). The bus interface is PCIe 5.0 x16, and it has no display outputs. Its DirectX, OpenGL, and Vulkan APIs are all listed as N/A, confirming it is not a graphics-oriented part.

The Intel Arc Graphics 48EU Mobile uses the Meteor Lake chip built on Xe-LPG architecture, manufactured on a 10 nm process at Intel. It has 384 shading units, 24 TMUs, and 8 ROPs. Memory is system shared, so capacity, bus width, and bandwidth are all system dependent. The base clock is 300 MHz with a boost clock of 1800 MHz. It uses a Ring Bus interface and supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The production status is listed as Active, while the MI325X has no production status entry.

The process node difference is significant: 5 nm versus 10 nm. The MI325X packs over 150 billion transistors onto a single monolithic die, while the Intel part’s transistor count and die size are not listed. The MI325X has no ROPs and no pixel rate, while the Intel part has 8 ROPs and a 14.40 GPixel/s pixel rate. The MI325X supports no graphics APIs, while the Intel part supports modern DirectX, OpenGL, and Vulkan versions. The MI325X uses dedicated HBM3e with a fixed 6.14 TB/s bandwidth, whereas the Intel part relies on system shared memory with system dependent bandwidth.

FAQ

The Verdict

The data points to two completely different product classes. The AMD Instinct MI325X is a 1000 W accelerator with 256 GB of HBM3e, 81.72 TFLOPS of FP32 throughput, and no display outputs. It targets compute workloads that demand massive memory capacity and bandwidth, such as large model training or inference. The Intel Arc Graphics 48EU Mobile is a 28 W integrated GPU with system shared memory, 1,382.4 GFLOPS of FP32, and modern graphics API support. It targets mobile devices where power draw and physical space are constrained.

For a user with a workstation or server that has PCIe 5.0 x16 and a robust power supply, the MI325X provides a compute density that the Arc part cannot approach: roughly 59 times the FP32 throughput and 29.5 times the FP16 throughput, along with a 6.14 TB/s memory bus versus a system dependent one. For a user building or buying a portable device, the Arc Graphics 48EU Mobile is the only viable option of the two, since the MI325X cannot output video and requires an OAM slot.

Neither part has benchmark scores in the database, so any performance claim must rest on specification-level analysis. The MI325X is the clear choice for raw compute and memory bandwidth. The Arc Graphics 48EU Mobile is the clear choice for integrated graphics in a low-power mobile system. There is no overlap in their intended use cases.
