AMD Instinct MI455X vs Intel Data Center GPU Max 1100 Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Instinct MI455X or the Intel Data Center GPU Max 1100. Both entries show an average benchmark score of 0, and the head-to-head comparison table is empty. Consequently, there are no wins recorded for either part, and no performance deltas can be calculated from measured results.

The absence of benchmark data means that direct performance comparisons cannot be made from empirical measurements. What the database does provide is a rich set of specification data that allows for a theoretical comparison of compute capabilities. The AMD Instinct MI455X delivers a peak FP32 throughput of 157.3 TFLOPS, while the Intel Data Center GPU Max 1100 delivers 22.22 TFLOPS in FP32. This represents a 7.08x advantage for the AMD part in raw single-precision floating-point throughput, a figure derived directly from the recorded specifications.

Similarly, for FP16 compute, the AMD Instinct MI455X again shows 157.3 TFLOPS with a 1:1 ratio, while the Intel Data Center GPU Max 1100 shows 22.22 TFLOPS with the same 1:1 ratio. The relative standing is identical to the FP32 comparison, with the AMD accelerator holding a 7.08x lead in peak half-precision performance as well.

Texture throughput tells a similar story. The AMD Instinct MI455X achieves a texture rate of 2,457.6 GTexel/s, compared to 694.4 GTexel/s for the Intel part. This gives AMD a 3.54x advantage in texel processing capacity. Both parts report a pixel rate of 0 MPixel/s, indicating that neither accelerator is designed for conventional rasterization output, consistent with their roles as data center compute accelerators.

The Intel Data Center GPU Max 1100 does include 56 ray tracing cores, a feature entirely absent from the AMD Instinct MI455X, which reports no ray tracing cores at all. This is a notable architectural differentiator, though its practical impact in a data center compute context is unclear from the data. The AMD part has no recorded RT cores, and the Intel part has 56, but no benchmark results exist to quantify any resulting performance difference.

Since the percentile versus all GPUs is recorded as 50 for both parts, the database places both accelerators at the median of all tracked GPUs. This is likely an artifact of the absence of benchmark data rather than a meaningful performance equivalence. Without measured scores, the percentile field cannot be interpreted as evidence of comparable real-world performance.

Architecture Differences

The AMD Instinct MI455X is built on the CDNA 5.0 architecture, while the Intel Data Center GPU Max 1100 uses Generation 12.5, also known by the chip name Ponte Vecchio. The manufacturing processes diverge significantly: AMD uses a 2 nm process from TSMC, while Intel uses a 10 nm process from its own foundry. This process difference contributes to a large disparity in transistor density, with the AMD chip achieving 107.0M transistors per square millimeter versus 78.1M for the Intel chip.

The physical scale of the two chips is starkly different. The AMD MI450 256CU chip packs 320,000 million transistors on a die size of 2990 mm². The Intel Ponte Vecchio chip contains 100,000 million transistors on a 1280 mm² die. The AMD chip is more than three times larger in transistor count and more than twice the die area. The transistor density advantage for AMD is 37.0% higher, reflecting the more advanced 2 nm node.

Memory architecture differs substantially. The AMD Instinct MI455X uses HBM4 memory totaling 432 GB, with a 24576-bit bus and 23.3 TB/s of bandwidth. The Intel Data Center GPU Max 1100 uses HBM2e memory totaling 48 GB, with an 8192-bit bus and 1.23 TB/s of bandwidth. The AMD part offers 9x the memory capacity and 18.94x the memory bandwidth. The memory clock rates also differ: AMD runs at 1900 MHz with 7.6 Gbps effective, while Intel runs at 600 MHz with 1200 Mbps effective.

Compute unit organization shows clear differences in scale. The AMD Instinct MI455X contains 32,768 shading units, 1,024 texture mapping units, and no ROPs. The Intel Data Center GPU Max 1100 contains 7,168 shading units, 448 TMUs, and no ROPs. AMD has 4.57x the shading units and 2.29x the TMUs. The Intel part is the only one of the two to include ray tracing cores, with 56 present, while the AMD part has none.

Power and physical requirements differ dramatically. The AMD Instinct MI455X has a TDP of 2300 W and requires a suggested PSU of 2700 W. It is an EAM module with no power connectors listed. The Intel Data Center GPU Max 1100 has a TDP of 300 W and a suggested PSU of 700 W. It is a dual-slot card with a single 12-pin power connector. The Intel card has a recorded length of 267 mm or 10.5 inches, while the AMD module has no recorded dimensions.

Bus interfaces also differ by generation. The AMD part uses PCIe 6.0 x16, while the Intel part uses PCIe 5.0 x16. Both have no display outputs. The AMD part reports no API support for DirectX, OpenGL, or Vulkan, while the Intel part reports DirectX 12 (12_1) and OpenGL 4.6 support, with Vulkan left unrecorded. The release dates are separated by roughly three and a half years: Intel launched on 2023-01-09, while AMD is dated 2026-07-22.

The Verdict

The recorded data paints a picture of two accelerators designed for different points in the data center spectrum. The AMD Instinct MI455X is a massive, high-power compute module with a TDP of 2300 W and a suggested PSU of 2700 W. It offers 432 GB of HBM4 memory, 23.3 TB/s of bandwidth, and 157.3 TFLOPS of FP32 throughput. The Intel Data Center GPU Max 1100 is a more conventional dual-slot card with a 300 W TDP, a 700 W suggested PSU, 48 GB of HBM2e, 1.23 TB/s of bandwidth, and 22.22 TFLOPS of FP32.

For applications that prioritize raw compute throughput and memory capacity, the AMD Instinct MI455X is the clear choice based on the specification data. Its FP32 and FP16 figures are 7.08x higher, its memory bandwidth is 18.94x higher, and its memory capacity is 9x larger. The 2 nm TSMC process and PCIe 6.0 interface indicate a newer generation design. The absence of any display outputs or conventional graphics APIs on the AMD part underscores its pure compute focus.

For deployments constrained by power and physical footprint, the Intel Data Center GPU Max 1100 offers a dramatically lower power envelope at 300 W versus 2300 W. It is the only one of the two with ray tracing cores, with 56 present. It also carries API support for DirectX 12 (12_1) and OpenGL 4.6, which the AMD part lacks entirely. Its 10 nm Intel process and PCIe 5.0 interface date it to an earlier generation, but its dual-slot form factor and single 12-pin power connector make it far easier to integrate into standard server chassis.

The lack of benchmark scores in the database means no empirical performance verdict can be issued. The data supports a specification-based conclusion: the AMD Instinct MI455X is engineered for maximum compute density and memory throughput, while the Intel Data Center GPU Max 1100 is engineered for moderate power consumption and broader API compatibility. Neither part has a recorded benchmark score, so the percentile ranking of 50 for both should be treated as a placeholder, not a performance equivalence. The choice between them, based strictly on the data, depends on whether the workload prioritizes the 7.08x compute lead and 18.94x bandwidth lead of the AMD module or the 7.67x lower power draw and standard card form factor of the Intel part.
