AMD Instinct MI308X vs Intel Arc 140V Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no benchmark scores for either the AMD Instinct MI308X or the Intel Arc 140V Mobile. The head-to-head benchmark table is empty, and the wins count for each product stands at zero. The average benchmark score for both GPUs is 0, and each sits at the 50th percentile among all GPUs in the database. This means no direct performance comparison can be drawn from measured results. The data simply does not include any frame rates, compute scores, or synthetic test outputs for these two accelerators. In the absence of measured numbers, any performance ranking between them would be speculative, so the analysis here relies exclusively on the architectural and specification differences recorded in the database.

Architecture Differences

The AMD Instinct MI308X and Intel Arc 140V Mobile represent fundamentally different design philosophies. The MI308X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm process at TSMC with 153,000 million transistors on a die size of 1017 mm². Its transistor density is 150.4 million per square millimeter. The Intel part uses the Xe2-LPG architecture on the Lunar Lake chip, manufactured on a 3 nm process at TSMC, with a die size of 172 mm² and an unknown transistor count.

The MI308X is a compute-oriented accelerator with 19,456 shading units, 1,216 texture mapping units, and zero ROPs. Its pixel rate is 0 MPixel/s because it has no display outputs. Texture rate reaches 2,553.6 GTexel/s. Floating point performance is 81.72 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The Intel Arc 140V Mobile, by contrast, is an integrated GPU with 1,024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. Its pixel rate is 62.40 GPixel/s and texture rate is 124.8 GTexel/s. FP32 performance is 3.994 TFLOPS, while FP16 reaches 7.987 TFLOPS, a 2:1 ratio that doubles the rate for half-precision work.

Memory configurations differ dramatically. The MI308X carries 192 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The Intel part uses system shared memory with a bus width also marked as system shared, and bandwidth is system dependent. Clock speeds show the MI308X running at a 1000 MHz base and 2100 MHz boost, with memory at 1300 MHz or 5.2 Gbps effective. The Intel chip has a 300 MHz base and 1950 MHz boost, with memory clock marked as system shared.

Power and physical design separate these products completely. The MI308X has a TDP of 750 W, uses an OAM Module slot width, has no power connectors listed, and requires a suggested PSU of 1150 W. It connects via PCIe 5.0 x16 and offers no display outputs. The Intel Arc 140V Mobile is an IGP with a 37 W TDP, uses the IGP bus interface, and has display outputs that are portable device dependent. The MI308X supports no DirectX, OpenGL, or Vulkan APIs, while the Intel part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release dates also differ. The MI308X launched on December 5, 2023, while the Intel Arc 140V Mobile arrived on September 23, 2024. The MI308X is the successor to Radeon Instinct, and the Intel part succeeds HD Graphics-M. Production status for the Intel part is marked as active, while the MI308X has no production status recorded.

Where Each One Wins

Without benchmark data, the wins must be inferred from the specification differences. The AMD Instinct MI308X dominates in raw compute throughput. Its FP32 output of 81.72 TFLOPS is roughly 20.5 times higher than the Intel part's 3.994 TFLOPS. Texture rate is also far higher at 2,553.6 GTexel/s versus 124.8 GTexel/s. Memory bandwidth of 5.32 TB/s on the MI308X dwarfs any system shared configuration, and the 192 GB capacity supports workloads that need massive datasets resident on the GPU. The absence of ROPs and display outputs confirms this is not a rendering device; it is built for compute accelerators, likely training and inference workloads that rely on high FP16 throughput. The 1:1 FP16 ratio means the MI308X maintains its 81.72 TFLOPS rate even in mixed-precision contexts.

The Intel Arc 140V Mobile wins in every category that matters for a client-side integrated GPU. It has 32 ROPs and a 62.40 GPixel/s pixel rate, enabling actual display output and rasterization. Its 8 ray tracing cores provide hardware acceleration for ray-traced graphics, something the MI308X lacks entirely. The Intel part supports the full DirectX 12 Ultimate feature set, OpenGL 4.6, and Vulkan 1.4, while the MI308X reports N/A for all three APIs. The 37 W TDP makes it suitable for thin-and-light laptops, whereas the 750 W TDP of the MI308X requires a dedicated server or workstation power delivery system. The Intel part also has a much smaller die at 172 mm² versus 1017 mm², and the newer 3 nm process node offers better density for its size.

The FP16 ratio difference also points to divergent strengths. The Intel Arc 140V Mobile doubles its FP16 rate to 7.987 TFLOPS, which helps with certain AI and media workloads. The MI308X keeps a 1:1 ratio, which is typical for accelerators where FP16 precision is the primary compute mode. The Intel part's system shared memory means it can flexibly use whatever system RAM is available, though bandwidth is system dependent and not comparable to the dedicated HBM3 stack on the MI308X.

The Verdict

The data shows two products with almost no overlap in purpose. The AMD Instinct MI308X is a 750 W OAM module with 192 GB of HBM3, 5.32 TB/s bandwidth, and 81.72 TFLOPS of FP16 compute. This is an accelerator for high-performance computing, large-scale AI training, or inference with massive model sizes. It has no display outputs, no graphics APIs, and no ROPs. Anyone needing a GPU for rendering, gaming, or desktop graphics cannot use this product. Anyone needing to process terabytes of data in parallel computation would find the MI308X's specifications far beyond what an integrated GPU can offer.

The Intel Arc 140V Mobile is a 37 W integrated GPU in the Lunar Lake chip. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, has 8 ray tracing cores, and outputs to portable device displays. Its 3.994 TFLOPS FP32 and 7.987 TFLOPS FP16 are modest but appropriate for a mobile IGP. It cannot approach the MI308X's raw throughput, memory capacity, or bandwidth, but it does not need to. It fits into a laptop, consumes far less power, and handles standard graphics workloads.

The choice depends entirely on the system context. For a server rack or workstation node with 1150 W PSU headroom and PCIe 5.0 connectivity, the MI308X delivers compute density that the Intel IGP cannot match. For a laptop or compact mobile device, the Intel Arc 140V Mobile is the only viable option given its form factor and power envelope. Neither product can substitute for the other. The MI308X's 50th percentile ranking among all GPUs reflects its narrow compute focus, not a general-purpose graphics capability. The Intel part's same percentile ranking reflects its position as a capable integrated solution, not a high-end discrete competitor.
