AMD Instinct MI300 vs Intel Arc 140T Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark comparisons between the AMD Instinct MI300 and the Intel Arc 140T Mobile. Both entries show an average benchmark score of 0, and both sit at the 50th percentile among all GPUs in the database. This means the quantitative comparison must rest entirely on the technical specifications and theoretical performance figures recorded for each part.

The AMD Instinct MI300 delivers 47.87 TFLOPS of FP32 compute, while the Intel Arc 140T Mobile delivers 4.813 TFLOPS. That places the MI300 at roughly 9.9 times the raw FP32 throughput of the Arc 140T Mobile. In FP16 workloads, the MI300 again posts 47.87 TFLOPS with a 1:1 ratio, meaning no throughput advantage is gained by switching to reduced precision. The Arc 140T Mobile, by contrast, reaches 9.626 TFLOPS in FP16 with a 2:1 ratio, effectively doubling its FP32 output when using FP16 data.

Texture throughput follows a similar pattern. The MI300 records a texture rate of 1,496.0 GTexel/s, compared to 150.4 GTexel/s for the Arc 140T Mobile, a difference of approximately 9.9 times. Pixel throughput tells a different story: the MI300 is recorded with a pixel rate of 0 MPixel/s, while the Arc 140T Mobile delivers 75.20 GPixel/s. This reflects a fundamental architectural split, the MI300 has no ROP units recorded, whereas the Arc 140T Mobile has 32 ROPs.

The MI300's memory subsystem is entirely separate from the compute comparison. It uses 128 GB of HBM3 memory across an 8192-bit bus, yielding 5.32 TB/s of bandwidth. The Arc 140T Mobile shares system memory with no dedicated VRAM, and its bandwidth is listed as system dependent, meaning no fixed figure can be assigned. The MI300's memory clock is recorded at 1300 MHz with 5.2 Gbps effective transfer, while the Arc 140T Mobile's memory clock is simply listed as system shared.

Where Each One Wins

The AMD Instinct MI300 wins decisively in any workload that depends on raw compute throughput or memory bandwidth. Its FP32 and FP16 figures exceed the Arc 140T Mobile by roughly an order of magnitude, and its 5.32 TB/s of dedicated HBM3 bandwidth dwarfs any system-shared memory configuration. The MI300 also has a far larger shading unit count, 14,080 units versus 1,024, and 880 TMUs versus 64, which explains its dominance in texture-heavy compute tasks.

The Intel Arc 140T Mobile wins in areas related to integration and graphics output. It is an integrated graphics processor (IGP) with a 35 W TDP, designed to operate within a mobile platform. It has 8 ray tracing cores, while the MI300 records none. The Arc 140T Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the MI300 lists N/A for all three APIs. The Arc 140T Mobile also has display outputs (portable device dependent), while the MI300 has no outputs at all.

For pixel processing, the Arc 140T Mobile is the clear winner with 75.20 GPixel/s against the MI300's 0 MPixel/s. The MI300 is not designed for rasterization or display; its architecture omits ROPs entirely. The Arc 140T Mobile, with 32 ROPs, handles traditional graphics rendering tasks that the MI300 simply cannot perform.

Clock speeds also favor the Arc 140T Mobile in boost frequency. The Intel part boosts to 2350 MHz, while the MI300 boosts to 1700 MHz. The base clocks are reversed: the MI300 runs at 1000 MHz base, while the Arc 140T Mobile runs at 300 MHz base. However, the MI300's much larger execution resource pool more than compensates for its lower boost clock in compute throughput.

Architecture Differences

The two processors come from different architectural families. The AMD Instinct MI300 uses CDNA 3.0, built on the Aqua Vanjaram chip, part of the Instinct (MIx) generation. The Intel Arc 140T Mobile uses Xe-LPG+, built on the Arrow Lake-H chip, part of the Arc Graphics-M (Arrow Lake) generation.

Both are fabricated on a 5 nm process at TSMC. The MI300 packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million transistors per square millimeter. The Arc 140T Mobile's transistor count and die size are recorded as unknown, so no density figure exists.

Memory architecture differs completely. The MI300 uses 128 GB of HBM3 on an 8192-bit bus with a fixed 5.32 TB/s bandwidth. The Arc 140T Mobile uses system shared memory, with type, bus width, and bandwidth all listed as system dependent. The MI300 has a dedicated memory clock of 1300 MHz with an effective 5.2 Gbps transfer rate; the Arc 140T Mobile has no independent memory clock.

The MI300 has 14,080 shading units, 880 TMUs, and 0 ROPs. The Arc 140T Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs. The MI300 records no ray tracing cores, while the Arc 140T Mobile has 8. Neither part lists tensor cores in the database.

Power and physical characteristics diverge sharply. The MI300 has a 600 W TDP, uses 2x 8-pin power connectors, and requires a 1000 W suggested PSU. It connects via PCIe 5.0 x16 and measures 267 mm in length and 111 mm in height. The Arc 140T Mobile has a 35 W TDP, uses no external power connectors, has no suggested PSU, connects via IGP, and is an integrated processor with no separate slot dimensions.

API support is another major split. The Arc 140T Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its compute-oriented design with no graphics rendering path.

Release dates differ by two years. The MI300 was released on 2023-01-03, while the Arc 140T Mobile was released on 2025-01-12. The MI300's predecessor is Radeon Instinct; the Arc 140T Mobile's predecessor is HD Graphics-M.

The Verdict

The data shows two processors with almost no functional overlap. The AMD Instinct MI300 is a high-power, compute-focused accelerator with 47.87 TFLOPS FP32, 128 GB of HBM3, and no display outputs. It is designed for server or workstation environments where massive parallel throughput and 5.32 TB/s of memory bandwidth matter. Its 600 W TDP and 2x 8-pin power requirement position it as a dedicated accelerator board, not an integrated solution.

The Intel Arc 140T Mobile is a 35 W integrated GPU for mobile platforms. It has 8 ray tracing cores, full DirectX 12 Ultimate support, and display outputs. Its 4.813 TFLOPS FP32 and 9.626 TFLOPS FP16 are modest compared to the MI300, but it delivers actual graphics rendering capability, which the MI300 completely lacks with its 0 MPixel/s pixel rate and N/A API support.

Anyone choosing between these two parts is not comparing similar products. The MI300 suits compute tasks like large-scale matrix operations, scientific simulation, or AI inference where FP32 and FP16 throughput and 5.32 TB/s bandwidth are the primary requirements. The Arc 140T Mobile suits mobile devices that need a functional integrated GPU with modern API support, ray tracing, and low power consumption.

The MI300's 14,080 shading units and 880 TMUs deliver 1,496.0 GTexel/s of texture rate, approximately 9.9 times the Arc 140T Mobile's 150.4 GTexel/s. But the Arc 140T Mobile's 32 ROPs give it 75.20 GPixel/s of pixel throughput, a capability the MI300 does not possess at all.

In terms of longevity, the Arc 140T Mobile remains in active production, while the MI300's production status is not recorded. The MI300 was released first, in January 2023, followed by the Arc 140T Mobile in January 2025.
