AMD Instinct MI300X vs Intel Arc 140V Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains a single benchmark entry for the AMD Instinct MI300X, while the Intel Arc 140V Mobile has no benchmark scores listed. The Geekbench OpenCL result for the MI300X is 317,994 points, placing it at the 100th percentile among all GPUs in the database. This means the MI300X sits at the absolute top of the recorded performance distribution, with no GPU scoring higher in the database's measurements.

The Intel Arc 140V Mobile, by contrast, holds the 50th percentile position with an average benchmark score of zero, indicating no recorded performance data exists for this part. The database shows no head-to-head benchmark comparisons between these two products, and neither side registers a win in the recorded wins fields.

For context on the MI300X's standing, the nearest rivals in the database provide useful reference points. The NVIDIA H200 NVL posts an average score of 334,891, which is 5% higher than the MI300X. The NVIDIA B200 reaches 345,482, an 8% advantage. On the other side, the NVIDIA L40S scores 295,763, which is 7.5% lower than the MI300X, and the NVIDIA RTX 6000 Ada Generation scores 287,237, a 10.7% deficit. These deltas show the MI300X is competitive with the top-tier accelerators in the database, trailing the H200 and B200 by single-digit percentages while leading the L40S and RTX 6000 by similar margins.

The Intel Arc 140V Mobile has no nearest rivals listed, so no comparative performance statements can be made from the database. Its 50th percentile ranking reflects the absence of measured data rather than a mid-pack performance result. Without benchmark scores, the Arc 140V cannot be positioned against the MI300X or any other GPU in the database on a performance basis.

Architecture Differences

The AMD Instinct MI300X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, fabricated on a 5 nm process at TSMC. The Intel Arc 140V Mobile uses the Xe2-LPG architecture on the Lunar Lake chip, also fabricated by TSMC but on a 3 nm process node. This process difference gives Intel a manufacturing advantage in density potential, though the MI300X deploys a far larger physical design.

The MI300X contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million transistors per mm². The Arc 140V's transistor count is listed as unknown, but its die size is 172 mm² with no density figure recorded. The sheer scale difference is substantial: the MI300X's die area is nearly six times larger than the Arc 140V's, reflecting the vastly different design goals of a data center accelerator versus a mobile integrated GPU.

Compute resources differ dramatically. The MI300X has 19,456 shading units and 1,216 texture mapping units, with zero ROPs recorded. The Arc 140V has 1,024 shading units, 64 TMUs, and 32 ROPs. The MI300X also lists 8 ray tracing cores for the Arc 140V, while the MI300X has no RT core count recorded. Neither part lists tensor cores.

Memory configurations could hardly be more different. The MI300X carries 192 GB of HBM3 memory across an 8192-bit bus, delivering 5.32 TB/s of bandwidth with a memory clock of 1300 MHz (5.2 Gbps effective). The Arc 140V uses system shared memory, with size, type, bus width, and bandwidth all dependent on the host system. This means the MI300X offers dedicated, massive-bandwidth memory while the Arc 140V relies on whatever system memory the laptop provides.

Clock speeds also reflect their roles. The MI300X runs at a 1000 MHz base clock and boosts to 2100 MHz. The Arc 140V has a 300 MHz base and 1950 MHz boost. Despite the lower base clock, the Arc 140V's boost is relatively close to the MI300X's, but the compute throughput tells the real story.

The MI300X delivers 81.72 TFLOPS of FP32 and 81.72 TFLOPS of FP16 at a 1:1 ratio. The Arc 140V delivers 3.994 TFLOPS FP32 and 7.987 TFLOPS FP16 at a 2:1 ratio. The MI300X's FP32 throughput is over 20 times higher than the Arc 140V's. Pixel and texture rates follow the same pattern: the MI300X records 0 MPixel/s (no ROPs) and 2,553.6 GTexel/s, while the Arc 140V records 62.40 GPixel/s and 124.8 GTexel/s.

Power and physical specifications diverge sharply. The MI300X has a 750 W TDP, uses an OAM Module slot width, has no power connectors, and recommends an 1150 W power supply. The Arc 140V has a 37 W TDP, is an IGP (integrated graphics processor), and lists no power supply recommendation. The MI300X uses PCIe 5.0 x16 for its bus interface, while the Arc 140V uses an IGP bus interface, meaning it connects directly to the CPU package rather than a separate expansion slot. The MI300X has no display outputs, while the Arc 140V's display outputs are portable device dependent.

API support also differs. The MI300X lists N/A for DirectX, OpenGL, and Vulkan, reflecting its compute-focused design. The Arc 140V supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it a fully featured graphics solution for consumer applications.

Release dates place these products roughly nine months apart. The MI300X launched on December 5, 2023, while the Arc 140V launched on September 23, 2024. The MI300X's predecessor is listed as Radeon Instinct, and the Arc 140V's predecessor is HD Graphics-M. Neither has a recorded successor.

The Verdict

The database shows two products with fundamentally different purposes. The AMD Instinct MI300X is a data center accelerator with massive compute resources, dedicated HBM3 memory, and a 750 W TDP. Its Geekbench OpenCL score of 317,994 places it at the 100th percentile, ahead of the NVIDIA L40S by 7.5% and the NVIDIA RTX 6000 Ada Generation by 10.7%, while trailing the NVIDIA H200 NVL by 5% and the NVIDIA B200 by 8%.

The Intel Arc 140V Mobile is an integrated GPU for laptops, with system shared memory, a 37 W TDP, and full consumer API support including DirectX 12 Ultimate and Vulkan 1.4. It has no recorded benchmark scores, so its performance cannot be quantified from the database.

For compute-intensive workloads where the MI300X applies, the data shows it is competitive with the top NVIDIA accelerators, sitting within single-digit percentages of the H200 and B200 while leading the L40S and RTX 6000. For mobile graphics duties, the Arc 140V is the only one of the two with display outputs and consumer API support, though no performance data exists to assess its capability.

The MI300X has no display outputs and no consumer graphics API support, making it unsuitable for any display or gaming role. The Arc 140V has no recorded compute benchmark, making it unquantifiable for data center-style workloads. Each product serves a distinct market segment, and the database provides no overlap in measured performance.
