AMD Radeon PRO W7400 vs AMD Ryzen Z2 GPU Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results for the AMD Radeon PRO W7400 and the AMD Ryzen Z2 GPU. Both entries hold identical average benchmark scores of zero and share the same 50th percentile ranking among all GPUs in the database. This absence of measured data means the comparative analysis must rely entirely on architectural specifications, clock behavior, and memory configuration rather than performance deltas.

Without benchmark scores, the theoretical compute ceiling can still be estimated from recorded specifications. The AMD Radeon PRO W7400 delivers 7.885 TFLOPS of FP32 throughput, while the AMD Ryzen Z2 GPU reaches 8.294 TFLOPS. That difference represents roughly 5% higher raw compute for the Ryzen Z2 GPU, driven by its substantially higher boost clock of 2700 MHz versus 1100 MHz. However, the Radeon PRO W7400 counters with a larger shading unit count: 1792 versus 768, meaning each individual unit in the Ryzen Z2 GPU must work far harder to achieve its higher aggregate throughput.

Pixel fill rates tell a similar story. The Ryzen Z2 GPU posts 86.40 GPixel/s, which is 22% higher than the Radeon PRO W7400's 70.40 GPixel/s. Texture fill rates are closer: 129.6 GTexel/s for the Ryzen Z2 GPU versus 123.2 GTexel/s for the Radeon PRO W7400, a margin of only 5%. These figures indicate that the Ryzen Z2 GPU holds a modest edge in rasterization throughput despite having fewer ROPs (32 versus 64) and fewer TMUs (48 versus 112).

Memory bandwidth diverges in the opposite direction. The Radeon PRO W7400 uses 8 GB of GDDR6 on a 128-bit bus, achieving 172.8 GB/s. The Ryzen Z2 GPU uses 16 GB of LPDDR5X on the same 128-bit bus, but only reaches 119.9 GB/s. That puts the Radeon PRO W7400 ahead by 44% in bandwidth, a significant advantage for texture-heavy workloads and high-resolution rendering.

Clock speeds reveal a striking gap. The Radeon PRO W7400 idles at a 330 MHz base clock and boosts to 1100 MHz, while the Ryzen Z2 GPU runs at 800 MHz base and 2700 MHz boost. The Ryzen Z2 GPU's boost clock is 145% higher than the Radeon PRO W7400's peak. Memory clocks also differ: 1350 MHz (10.8 Gbps effective) for the Radeon PRO W7400 versus 937 MHz (7.5 Gbps effective) for the Ryzen Z2 GPU.

Architecture Differences

Both GPUs share the RDNA 3.0 architecture from AMD, but they are built on different process nodes and fabricated for different roles. The Radeon PRO W7400 uses the Navi 33 chip on a 6 nm TSMC process, codenamed Hotpink Bonefish, and belongs to the Radeon Pro Navi (Navi III Series) generation. The Ryzen Z2 GPU uses the Hawk Point chip on a 4 nm TSMC process and is classified under Console GPU (AMD).

The transistor counts reflect the process disparity. The Radeon PRO W7400 packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The Ryzen Z2 GPU contains 25,390 million transistors in a smaller 178 mm² die, achieving 142.6 million per square millimeter. The Ryzen Z2 GPU therefore crams nearly twice the transistor density into a smaller physical area, a direct consequence of the tighter 4 nm node.

Shading resources differ substantially. The Radeon PRO W7400 carries 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The Ryzen Z2 GPU halves those counts: 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. Despite having fewer resources, the Ryzen Z2 GPU compensates with much higher clock frequencies to reach comparable or better peak throughput.

Memory architecture separates the two designs more clearly. The Radeon PRO W7400 uses dedicated GDDR6 VRAM with a 128-bit bus and 172.8 GB/s bandwidth. The Ryzen Z2 GPU employs unified LPDDR5X system memory, also on a 128-bit bus, but with a lower 119.9 GB/s bandwidth. The capacity differs as well: 8 GB for the Radeon PRO W7400 versus 16 GB for the Ryzen Z2 GPU. The Ryzen Z2 GPU's memory operates at 937 MHz (7.5 Gbps effective), while the Radeon PRO W7400's memory runs at 1350 MHz (10.8 Gbps effective).

Power envelopes diverge sharply. The Radeon PRO W7400 has a 55 W TDP and a suggested PSU rating of 250 W, configured as a single-slot card with no power connectors. The Ryzen Z2 GPU draws only 28 W TDP, with no suggested PSU listed. The Radeon PRO W7400 is a physical expansion card measuring 168 mm in length, 69 mm in height, and 20 mm in width, while the Ryzen Z2 GPU has no recorded dimensions or slot width.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the Radeon PRO W7400 offering 4x DisplayPort 2.1 and the Ryzen Z2 GPU providing a single USB Type-C output. The Radeon PRO W7400 connects via PCIe 4.0 x8, while the Ryzen Z2 GPU has no recorded bus interface.

Where Each One Wins

The Radeon PRO W7400 wins clearly in memory bandwidth, delivering 172.8 GB/s versus 119.9 GB/s for the Ryzen Z2 GPU, a 44% advantage. That bandwidth edge, combined with dedicated GDDR6 memory and a full complement of 64 ROPs, makes it better suited for workloads that stream large textures or require high fill rates at high resolutions. Its 4x DisplayPort 2.1 outputs and single-slot form factor with no power connectors position it as a workstation-oriented card for multi-display professional environments. The 55 W TDP with a 250 W suggested PSU indicates a self-contained power design that does not rely on external connectors.

The Ryzen Z2 GPU wins on raw compute throughput, with 8.294 TFLOPS FP32 versus 7.885 TFLOPS for the Radeon PRO W7400. It also leads in pixel rate (86.40 GPixel/s versus 70.40 GPixel/s) and texture rate (129.6 GTexel/s versus 123.2 GTexel/s). Its 16 GB memory capacity is double that of the Radeon PRO W7400, which matters for workloads that need large working sets even at lower bandwidth. The 28 W TDP is less than half of the Radeon PRO W7400's 55 W, suggesting an integrated-class part designed for compact or mobile systems. The 4 nm process with 142.6 million transistors per square millimeter indicates a more modern fabrication approach.

The Radeon PRO W7400 offers more shading units (1792 versus 768), more TMUs (112 versus 48), more ROPs (64 versus 32), and more ray tracing cores (28 versus 12). These resource advantages mean the Radeon PRO W7400 can sustain parallel workloads across a wider array of execution units, even if each unit runs at a lower clock. The Ryzen Z2 GPU compensates with clock speed, boosting to 2700 MHz versus 1100 MHz, which explains how it achieves higher peak rates with fewer units.

For ray tracing specifically, the Radeon PRO W7400's 28 RT cores more than double the Ryzen Z2 GPU's 12, suggesting a stronger ray tracing throughput capability. For general compute, the Ryzen Z2 GPU's higher FP32 figure implies better raw math throughput. The choice depends on whether the workload favors memory bandwidth and parallel execution units (Radeon PRO W7400) or clock-driven compute and memory capacity (Ryzen Z2 GPU).
