AMD Instinct MI455X vs Intel Arc 130T Mobile Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Instinct MI455X or the Intel Arc 130T Mobile. Both entries show an average benchmark score of zero, and the head-to-head benchmark list is empty. Consequently, there are no wins recorded for either product in direct comparison. The percentile versus all GPUs is identical for both, at 50, which places them at the median of the database distribution, but this is a placeholder ranking rather than a result derived from measured performance.

Without benchmark data, the comparison must rely on the recorded specifications. The AMD Instinct MI455X delivers 157.3 TFLOPS of FP32 compute, while the Intel Arc 130T Mobile delivers 3.942 TFLOPS. That difference is substantial: the AMD part offers roughly 40 times the raw single-precision throughput. In FP16, the AMD card again provides 157.3 TFLOPS, while the Intel chip provides 7.885 TFLOPS, a 20-fold gap. The texture rate tells a similar story: the MI455X reaches 2,457.6 GTexel/s, versus 123.2 GTexel/s for the Arc 130T Mobile. The pixel rate, however, is inverted in an unusual way: the MI455X is recorded at 0 MPixel/s, while the Intel part is listed at 61.60 GPixel/s. This reflects the fundamentally different roles of the two products, not a real rendering capability advantage for the smaller chip.

Memory bandwidth is another area of extreme divergence. The MI455X has a 23.3 TB/s memory bandwidth over a 24576-bit bus, using 432 GB of HBM4 memory. The Arc 130T Mobile uses System Shared memory, with bandwidth described as System Dependent and a bus width of System Shared. These are not comparable numbers in the conventional sense, but the recorded data confirms that the AMD accelerator is designed for memory-bound compute workloads, whereas the Intel mobile graphics processor relies on shared system memory with variable performance.

Clock speeds differ as well. The MI455X has a base clock of 1000 MHz and a boost clock of 2400 MHz. The Arc 130T Mobile runs at a 300 MHz base and 2200 MHz boost. The AMD part also has a memory clock of 1900 MHz, which translates to 7.6 Gbps effective. The Intel chip has no dedicated memory clock because it uses system shared memory. These figures indicate that the AMD accelerator operates at higher clocks and sustains them across a much larger silicon footprint, while the Intel part uses lower clocks to fit within a 35 W envelope.

The process nodes and transistor counts are also recorded. The MI455X uses a 2 nm process at TSMC, with 320,000 million transistors on a 2990 mm² die, giving a transistor density of 107.0M per mm². The Arc 130T Mobile uses a 5 nm process at TSMC, but its transistor count and die size are listed as unknown. The absence of transistor data for the Intel part limits any density comparison, but the recorded figures for the AMD chip indicate an extremely large, high-density accelerator.

The Verdict

The data shows two products built for entirely different purposes. The AMD Instinct MI455X is a compute accelerator with no display outputs, no DirectX, OpenGL, or Vulkan API support, and a TDP of 2300 W. The Intel Arc 130T Mobile is an integrated graphics processor for laptops, with DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4 support, display outputs described as Portable Device Dependent, and a TDP of 35 W. These are not rivals in any practical sense, and the database confirms this with zero head-to-head benchmark wins for either side.

For compute workloads that require massive FP32 or FP16 throughput, the MI455X is the only choice from these two. Its 157.3 TFLOPS in both precisions, 23.3 TB/s bandwidth, and 432 GB memory capacity place it in a class that the Arc 130T Mobile cannot approach. The Intel part delivers 3.942 TFLOPS of FP32 and 7.885 TFLOPS of FP16, figures that are suitable for integrated graphics in a mobile context but not for data center or scientific computing.

For graphics rendering and display output, the Arc 130T Mobile is the functional product. It has 28 ROPs and a pixel rate of 61.60 GPixel/s, while the MI455X has 0 ROPs and a pixel rate of 0 MPixel/s. The AMD accelerator has no display outputs, meaning it cannot drive a monitor. The Intel chip, by contrast, is designed to be integrated into a portable device with display outputs dependent on the host system.

The power requirements confirm this split. The MI455X needs a 2700 W suggested PSU, while the Arc 130T Mobile fits within a 35 W TDP and has no suggested PSU listed. Anyone selecting between these two based on the database should first determine whether the workload is compute or graphics, because the recorded specifications do not overlap.

Where Each One Wins

The AMD Instinct MI455X wins in raw compute throughput. Its FP32 performance of 157.3 TFLOPS is roughly 40 times the Arc 130T Mobile's 3.942 TFLOPS. Its FP16 performance of 157.3 TFLOPS is about 20 times the Intel part's 7.885 TFLOPS. Texture rate favors the AMD accelerator at 2,457.6 GTexel/s versus 123.2 GTexel/s. Memory bandwidth favors the MI455X overwhelmingly, with 23.3 TB/s versus the System Dependent bandwidth of the Intel chip. The MI455X also has a larger memory pool at 432 GB, compared to System Shared for the Arc 130T Mobile.

The Intel Arc 130T Mobile wins in pixel throughput and feature support. Its pixel rate of 61.60 GPixel/s exceeds the MI455X's 0 MPixel/s. The Intel part has 28 ROPs, while the AMD accelerator has 0 ROPs. The Arc 130T Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI455X lists N/A for all three APIs. The Intel chip also has 7 ray tracing cores, whereas the MI455X has no recorded ray tracing cores. Display outputs exist on the Intel part, described as Portable Device Dependent, while the MI455X has no outputs at all.

Clock speed comparisons show a mixed picture. The MI455X has a higher base clock at 1000 MHz versus 300 MHz, and a higher boost clock at 2400 MHz versus 2200 MHz. However, the Arc 130T Mobile achieves its pixel rate with fewer shading units (896 versus 32768) and fewer TMUs (56 versus 1024), which indicates a more graphics-oriented design despite lower absolute clock rates.

The MI455X also leads in bus interface. It uses PCIe 6.0 x16, while the Arc 130T Mobile uses IGP. The AMD part has an EAM Module slot width, versus IGP for Intel. These differences reinforce that the MI455X is a discrete accelerator and the Arc 130T Mobile is an integrated solution.
