AMD Radeon PRO W7400 vs AMD Ryzen Z1 GPU Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark comparisons between the AMD Radeon PRO W7400 and the AMD Ryzen Z1 GPU. Both entries sit at the 50th percentile among all GPUs in the database, with an average benchmark score of zero for each. This means the two parts cannot be ranked against one another using measured performance results. What the database does provide is a full set of technical specifications, and from those specifications the performance envelope of each product can be inferred.

The Radeon PRO W7400 delivers a peak FP32 compute throughput of 7.885 TFLOPS, while the Ryzen Z1 GPU reaches 2.560 TFLOPS. That places the PRO W7400 at roughly three times the raw single-precision throughput of the Z1 GPU. In FP16 work, the PRO W7400 also outputs 7.885 TFLOPS at a 1:1 ratio, whereas the Z1 GPU achieves 5.120 TFLOPS at a 2:1 ratio. The PRO W7400's pixel rate of 70.40 GPixel/s and texture rate of 123.2 GTexel/s far exceed the Z1 GPU's 20.00 GPixel/s and 40.00 GTexel/s. Memory bandwidth tells a similar story: the PRO W7400 moves 172.8 GB/s over a 128-bit GDDR6 interface, while the Z1 GPU manages 51.20 GB/s across a 64-bit LPDDR5 bus.

The Ryzen Z1 GPU does hold advantages in clock speeds. Its base clock of 1500 MHz and boost clock of 2500 MHz are substantially higher than the PRO W7400's 330 MHz base and 1100 MHz boost. However, the PRO W7400's larger execution resource pool, 1792 shading units versus 256, and its 112 texture mapping units versus 16, more than compensate for the lower clocks. The PRO W7400 also fields 64 ROPs against the Z1 GPU's 8, and 28 ray tracing cores against 4. These are large structural differences that point to the PRO W7400 as the substantially faster part in almost every workload category.

Architecture Differences

Both GPUs use AMD's RDNA 3.0 architecture and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The underlying silicon, however, differs significantly. The Radeon PRO W7400 is built on the Navi 33 chip, codenamed Hotpink Bonefish, and belongs to the Radeon Pro Navi (Navi III Series) generation. The Ryzen Z1 GPU uses the Phoenix chip and is classified under Console GPU (AMD) generation. Both are fabricated by TSMC, but on different nodes: the PRO W7400 uses a 6 nm process, while the Z1 GPU uses a 4 nm process.

Transistor counts reflect the different design goals. The Z1 GPU's Phoenix die packs 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6M per mm². The PRO W7400's Navi 33 die holds 13,300 million transistors on a 204 mm² die, for a density of 65.2M per mm². The Z1 GPU is the denser chip despite being smaller in area, a direct result of the more advanced 4 nm node. The PRO W7400 is the larger physical die, which accommodates its much larger execution engine.

Memory architecture is another clear divider. The PRO W7400 uses 8 GB of GDDR6 on a 128-bit bus, while the Z1 GPU uses 16 GB of LPDDR5 on a 64-bit bus. The GDDR6 solution provides 172.8 GB/s of bandwidth, more than triple the Z1 GPU's 51.20 GB/s. The Z1 GPU makes up for this with double the capacity. The memory clock rates also differ: the PRO W7400 runs at 1350 MHz with 10.8 Gbps effective, while the Z1 GPU runs at 800 MHz with 6.4 Gbps effective.

Power and physical design diverge sharply. The PRO W7400 is rated at 55 W TDP with a suggested PSU of 250 W, requires no power connectors, and occupies a single slot. Its dimensions are 168 mm in length, 69 mm in height, and 20 mm in width. The Z1 GPU is rated at 30 W TDP, also requires no power connectors, but its dimensions are listed as 280 mm in length, 111 mm in height, and 21 mm in width. The Z1 GPU lists no slot width and no bus interface, while the PRO W7400 uses PCIe 4.0 x8. Display outputs also differ: the PRO W7400 provides 4x DisplayPort 2.1, while the Z1 GPU lists no outputs.

Where Each One Wins

The Radeon PRO W7400 wins in raw compute, rendering throughput, and memory bandwidth. Its 7.885 TFLOPS FP32 performance, 70.40 GPixel/s pixel rate, and 123.2 GTexel/s texture rate make it suitable for heavy graphics workloads, professional rendering, and high-resolution output. The 8 GB GDDR6 frame buffer with 172.8 GB/s bandwidth supports high-bandwidth tasks such as texture streaming and large framebuffer operations. The 28 ray tracing cores give it a meaningful advantage in ray-traced workloads over the Z1 GPU's 4 RT cores. The 4x DisplayPort 2.1 outputs allow multi-monitor professional configurations, and the PCIe 4.0 x8 interface provides a modern host connection.

The Ryzen Z1 GPU wins in energy efficiency per watt at the specification level. Its 30 W TDP is lower than the PRO W7400's 55 W TDP. It also offers 16 GB of memory capacity, double the PRO W7400's 8 GB, which can be an advantage for workloads that require large datasets to reside in local memory rather than streaming from system memory. The 4 nm process node gives it a density advantage, and its higher clock speeds, 1500 MHz base and 2500 MHz boost, suggest strong per-clock efficiency. The Z1 GPU's FP16 throughput of 5.120 TFLOPS at a 2:1 ratio indicates its FP16 path is designed for accelerated half-precision work, whereas the PRO W7400 runs FP16 at a 1:1 ratio with FP32.

The PRO W7400 is positioned for professional graphics with its single-slot form factor, no external power requirement, and four DisplayPort outputs. The Z1 GPU, with no display outputs and a console GPU classification, is designed for integration into embedded or console-style systems where the host handles display and the GPU focuses on compute. The Z1 GPU's larger physical footprint, 280 mm length versus 168 mm, and its 30 W TDP suggest a board-level or system-level integration rather than a standalone add-in card.
