AMD Instinct MI300A vs Intel Arc Graphics 128EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Instinct MI300A and the Intel Arc Graphics 128EU Mobile shows no direct head-to-head benchmark results. The database contains no measured scores for either part in a shared test suite, so the comparison rests entirely on the specification sheets and derived performance figures.

The most decisive divergence appears in raw compute throughput. The AMD Instinct MI300A delivers 61.29 TFLOPS of FP32 performance, while the Intel Arc Graphics 128EU Mobile produces 4.608 TFLOPS. This is a 13.3x difference in favor of the AMD part, a gap that dwarfs any other contrast between the two. The MI300A also reaches a texture rate of 1,915.2 GTexel/s, compared to 144.0 GTexel/s for the Intel chip, a 13.3x margin as well. Both numbers trace back to the fundamental difference in shading units: 14,592 for the AMD accelerator versus 1,024 for the Intel integrated GPU.

Pixel throughput tells a different story, however. The Intel Arc Graphics 128EU Mobile posts 72.00 GPixel/s, while the AMD Instinct MI300A records 0 MPixel/s. This is not a competitive loss but a structural one: the MI300A has no raster output units and no display outputs, so it cannot generate pixels at all. The Intel part, with 32 ROPs and integrated display support, handles pixel generation as a normal function. Any workload that depends on rasterization or frame output belongs exclusively to the Intel chip.

Memory bandwidth also separates the two dramatically. The AMD Instinct MI300A uses 128 GB of HBM3 across an 8192-bit bus, producing 5.32 TB/s of bandwidth. The Intel Arc Graphics 128EU Mobile uses system shared memory with system dependent bandwidth, so no fixed figure exists for comparison. The AMD part operates at a memory clock of 1300 MHz (5.2 Gbps effective), while the Intel part has no dedicated memory clock because it borrows from the host system.

Clock speeds show a different relationship. The Intel chip has a base clock of 300 MHz and a boost clock of 2250 MHz. The AMD chip has a base clock of 1000 MHz and a boost clock of 2100 MHz. Intel's boost clock runs 150 MHz higher, but this does little to close the compute gap given the massive difference in execution resources.

Power draw is equally lopsided. The AMD Instinct MI300A has a TDP of 750 W and a suggested PSU of 1150 W. The Intel Arc Graphics 128EU Mobile has a TDP of 28 W, a 26.8x difference. The AMD part is an OAM module with no power connectors listed, while the Intel part is an IGP with no separate power requirement. The power envelope alone indicates entirely different deployment scenarios.

The Verdict

The data positions these two products in separate categories with no meaningful overlap. The AMD Instinct MI300A is a compute accelerator built for massive parallel workloads. Its 61.29 TFLOPS of FP32, 5.32 TB/s of memory bandwidth, and 128 GB of HBM3 make it suitable for tasks that saturate large data arrays, such as scientific simulation or machine learning training. The absence of display outputs and raster units confirms that it never targets graphics output.

The Intel Arc Graphics 128EU Mobile is an integrated graphics processor for portable devices. Its 4.608 TFLOPS of FP32 and 72.00 GPixel/s of pixel rate serve display workloads, light gaming, and media acceleration. The 28 W TDP fits within a laptop power budget, and the system shared memory approach avoids dedicated VRAM costs.

For compute-focused buyers, the MI300A is the only choice with the recorded specifications. For graphics output, the Intel part is the only one that can produce it. No benchmark score exists to suggest any crossover. The percentile data shows both at 50th percentile versus all GPUs, but this reflects the absence of benchmark entries rather than comparative performance. The verdict from the specifications is unambiguous: the MI300A dominates compute, the Intel part dominates pixel output, and neither can substitute for the other.

Architecture Differences

The AMD Instinct MI300A uses the CDNA 3.0 architecture on TSMC's 5 nm process. Its chip is codenamed Aqua Vanjaram, with 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². This is a dedicated compute architecture with no graphics pipeline, reflected in its zero ROPs and missing display outputs. It belongs to the Instinct (MIx) generation and succeeds the Radeon Instinct line.

The Intel Arc Graphics 128EU Mobile uses the Xe-LPG architecture on Intel's 10 nm process. Its chip is Meteor Lake, and it belongs to the Arc Graphics-M (Meteor Lake) generation. It is an integrated GPU with a full graphics pipeline, including 32 ROPs and portable device dependent display outputs. It succeeds the HD Graphics-M line.

The API support differs completely. The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The AMD part reports N/A for DirectX, OpenGL, and Vulkan, confirming that it has no graphics API compatibility. This is a decisive architectural distinction: the MI300A cannot run graphics workloads at all, while the Intel part is designed for them.

The bus interface also differs. The AMD part uses PCIe 5.0 x16, a high-bandwidth external connection. The Intel part uses a Ring Bus, reflecting its integration into the host processor. The MI300A's slot width is listed as OAM Module, while the Intel part is IGP. These form factors reinforce the architectural split.

Where Each One Wins

The AMD Instinct MI300A wins in all compute-intensive categories. Its FP32 throughput of 61.29 TFLOPS is 13.3x the Intel part's 4.608 TFLOPS. Its texture rate of 1,915.2 GTexel/s is 13.3x the Intel part's 144.0 GTexel/s. Its memory bandwidth of 5.32 TB/s, backed by 128 GB of HBM3, has no comparable figure on the Intel side because the Intel part relies on system shared memory. The MI300A also has a higher base clock at 1000 MHz versus 300 MHz. For workloads that stress raw math throughput, large memory arrays, or sustained memory bandwidth, the MI300A is the clear winner by every recorded measure.

The Intel Arc Graphics 128EU Mobile wins in every category related to graphics output. It produces 72.00 GPixel/s while the AMD part produces 0 MPixel/s. It has 32 ROPs while the AMD part has 0. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the AMD part supports none. It has a higher boost clock at 2250 MHz versus 2100 MHz. It also operates at 28 W versus 750 W, a 26.8x power advantage that makes it suitable for portable devices. For display output, rasterization, or any graphics API workload, the Intel part is the only functional option.

The AMD part wins on process technology with 5 nm versus 10 nm, and on transistor count with 153,000 million versus no listing for Intel. The Intel part wins on production status, listed as active, while the AMD part has no production status listed. The release dates are nearly identical, with the AMD part launching on 2023-12-05 and the Intel part on 2023-12-13, so neither has a meaningful temporal advantage.

The usage split is clean: the MI300A serves compute acceleration in a data center or high-performance computing context, while the Intel Arc Graphics 128EU Mobile serves graphics and display tasks in a mobile or integrated context. The data does not support any middle ground.
