AMD Radeon PRO W7400 vs Intel Data Center GPU Max Subsystem Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark entries for either the AMD Radeon PRO W7400 or the Intel Data Center GPU Max Subsystem. Both entries show an average benchmark score of zero, and the head-to-head comparison table is empty. Consequently, there are no measurable wins for either product in our recorded results.

Both GPUs sit at the 50th percentile among all GPUs tracked in the database. This percentile placement is identical for both devices, indicating that neither product has accumulated enough benchmark submissions to establish a differentiated performance profile. Without recorded scores, the data cannot confirm which device delivers superior frame rates, compute throughput, or rendering performance in any specific workload.

The absence of benchmark data should not be interpreted as a lack of capability. The two products target entirely different segments of the GPU market, and their specifications suggest strongly divergent performance envelopes. The AMD Radeon PRO W7400 is a professional workstation graphics card with a 55 W thermal design power, while the Intel Data Center GPU Max Subsystem is an accelerator with a 2400 W thermal design power. The raw compute figures in the specification records, 7.885 TFLOPS FP32 for the AMD card versus 52.43 TFLOPS FP32 for the Intel subsystem, indicate a substantial theoretical performance gap, but these are not benchmark scores and cannot be validated against measured results in the database.

Where Each One Wins

Based on the specification records, the Intel Data Center GPU Max Subsystem holds advantages in raw compute resources and memory capacity. It offers 16,384 shading units versus 1,792 for the AMD card, 1024 texture mapping units versus 112, and 128 ray tracing cores versus 28. Its FP32 throughput of 52.43 TFLOPS exceeds the AMD card by a wide margin. The Intel subsystem also carries 128 GB of HBM2e memory with 3.21 TB/s bandwidth, a 16-fold capacity increase and a significantly wider memory bus.

The AMD Radeon PRO W7400 wins in areas relevant to professional workstation use. It provides four DisplayPort 2.1 outputs, while the Intel subsystem has no display outputs at all. The AMD card supports DirectX 12 Ultimate, a higher specification than the Intel card's DirectX 12. The AMD card also draws only 55 W, compared to 2400 W for the Intel subsystem, and requires no power connectors, whereas the Intel card uses a 16-pin connector. The AMD card is single-slot, 168 mm long, and 20 mm wide, making it compatible with compact workstation chassis.

The Intel Data Center GPU Max Subsystem posts a texture rate of 1,638.4 GTexel/s against 123.2 GTexel/s for the AMD card. The AMD card records a pixel rate of 70.40 GPixel/s, while the Intel subsystem records 0 MPixel/s, consistent with its lack of display outputs and its role as a compute accelerator rather than a rendering device.

Specification Differences

The two GPUs differ across nearly every recorded specification field. The AMD Radeon PRO W7400 uses the Navi 33 chip based on RDNA 3.0 architecture with the codename Hotpink Bonefish. The Intel Data Center GPU Max Subsystem uses the Ponte Vecchio chip based on Generation 12.5 architecture with no codename recorded.

The AMD card is built on a 6 nm process at TSMC with 13,300 million transistors on a 204 mm² die. The Intel subsystem is built on Intel's 10 nm process with 100,000 million transistors on a 1280 mm² die. Transistor density is 65.2M per mm² for the AMD card and 78.1M per mm² for the Intel subsystem.

Clock speeds differ substantially. The AMD card runs at a base clock of 330 MHz and a boost clock of 1100 MHz, with memory at 1350 MHz (10.8 Gbps effective). The Intel subsystem runs at a base clock of 900 MHz and a boost clock of 1600 MHz, with memory at 1565 MHz (3.1 Gbps effective).

Memory configurations are entirely different. The AMD card uses 8 GB GDDR6 with a 128-bit bus and 172.8 GB/s bandwidth. The Intel subsystem uses 128 GB HBM2e with an 8192-bit bus and 3.21 TB/s bandwidth.

Compute unit counts diverge sharply. The AMD card has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The Intel subsystem has 16,384 shading units, 1,024 TMUs, 0 ROPs, and 128 ray tracing cores. Neither product lists tensor cores.

Power and physical characteristics differ. The AMD card has a 55 W TDP, a single-slot design, no power connectors, and a suggested PSU of 250 W. The Intel subsystem has a 2400 W TDP, a dual-slot design, one 16-pin power connector, and a suggested PSU of 2800 W.

The bus interfaces differ: PCIe 4.0 x8 for the AMD card versus PCIe 5.0 x16 for the Intel subsystem. The AMD card measures 168 mm by 69 mm by 20 mm. The Intel subsystem measures 267 mm in length with height and width unrecorded.

Release dates differ. The AMD Radeon PRO W7400 was released on 2025-08-02, while the Intel Data Center GPU Max Subsystem was released on 2023-01-09. The AMD card's predecessor is recorded as Radeon Pro Vega, while the Intel card's successor is recorded as H3C Graphics.

Architecture Differences

The AMD Radeon PRO W7400 uses RDNA 3.0 architecture, which the database associates with the Navi 33 chip and the codename Hotpink Bonefish. This architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The FP16 rate is equal to the FP32 rate at 7.885 TFLOPS, indicating a 1:1 ratio.

The Intel Data Center GPU Max Subsystem uses Generation 12.5 architecture with the Ponte Vecchio chip. It supports DirectX 12 (12_1) and OpenGL 4.6, but Vulkan support is not recorded. The FP16 rate is also 1:1 with FP32 at 52.43 TFLOPS.

The Intel subsystem uses HBM2e memory, a high-bandwidth stacked memory technology, whereas the AMD card uses discrete GDDR6 memory. The memory bus width difference is extreme: 8192 bits for the Intel subsystem versus 128 bits for the AMD card.

The Intel subsystem has no ROPs and no display outputs, which aligns with its role as a data center compute accelerator. The AMD card has 64 ROPs and four DisplayPort 2.1 outputs, supporting its role as a workstation graphics card. The Intel subsystem's pixel rate is recorded as 0 MPixel/s, reinforcing that it is not designed for rasterization output.

The AMD card draws power exclusively from the PCIe slot with no external power connectors, while the Intel subsystem requires a 16-pin connector and a suggested 2800 W PSU. These architectural choices reflect fundamentally different deployment scenarios.

The Verdict

The data supports a clear split by use case. The AMD Radeon PRO W7400 is the appropriate choice for workstation graphics tasks that require display output, DirectX 12 Ultimate support, and modest power consumption. Its 55 W TDP, single-slot profile, 168 mm length, and lack of power connectors make it suitable for systems with limited space and thermal headroom. Its four DisplayPort 2.1 outputs and 8 GB GDDR6 memory serve rendering and professional visualization workloads.

The Intel Data Center GPU Max Subsystem is positioned for compute-intensive data center workloads. Its 52.43 TFLOPS FP32 rating, 128 GB HBM2e memory, 3.21 TB/s bandwidth, and 16,384 shading units provide substantially higher theoretical compute capacity. The absence of display outputs and the 2400 W TDP indicate a server accelerator designed for batch processing and parallel computation rather than interactive graphics.

Neither product has recorded benchmark scores in the database, so the verdict rests on specification analysis. The AMD card delivers a complete workstation feature set with display connectivity and a modern API profile. The Intel subsystem offers massive memory capacity and raw compute throughput at the cost of power and physical footprint. Buyers seeking a desktop or workstation GPU with monitor support should select the AMD Radeon PRO W7400. Buyers deploying a high-power accelerator in a data center environment should select the Intel Data Center GPU Max Subsystem. The 50th percentile ranking for both products reflects the absence of benchmark submissions, not equivalence in performance.
