AMD Radeon PRO W7800 vs AMD Ryzen Z2 GPU Comparison

# Where Each One Wins

The AMD Radeon PRO W7800 and the AMD Ryzen Z2 GPU occupy entirely different segments of the GPU landscape, and the recorded data reflects that separation clearly. The W7800 is a professional workstation graphics card built for compute-heavy workloads, while the Ryzen Z2 GPU is a console-class integrated graphics solution operating within a much lower power envelope.

The benchmark data shows no direct head-to-head tests between the two parts, but the aggregate scores tell the story. The Radeon PRO W7800 achieves an average benchmark score of 164,894, placing it in the 97th percentile of all GPUs in the database. The Ryzen Z2 GPU has no recorded benchmark scores and sits at the 50th percentile with an average score of zero. This is not a close competition; the W7800 dominates every measurable compute metric.

In terms of raw compute throughput, the W7800 delivers 45.25 TFLOPS of FP32 performance versus 8.294 TFLOPS for the Ryzen Z2 GPU, a 5.5x advantage. The FP16 comparison is even more lopsided: the W7800 produces 90.50 TFLOPS with a 2:1 ratio, while the Ryzen Z2 GPU manages 8.294 TFLOPS at a 1:1 ratio. The W7800 also leads decisively in texture rate at 707.0 GTexel/s against 129.6 GTexel/s, and in pixel rate at 323.2 GPixel/s versus 86.40 GPixel/s.

Memory capacity and bandwidth follow the same pattern. The W7800 carries 32 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The Ryzen Z2 GPU has 16 GB of LPDDR5X on a 128-bit bus, yielding 119.9 GB/s. That is a 4.8x bandwidth advantage for the workstation card.

Where the Ryzen Z2 GPU does win is in power efficiency and physical footprint. Its 28 W TDP is dramatically lower than the W7800's 260 W, and it requires no power connectors or suggested PSU rating. The W7800 is a dual-slot card measuring 280 mm in length, while the Ryzen Z2 GPU has no recorded dimensions, consistent with an embedded or mobile-class part. The Ryzen Z2 GPU also uses a smaller 4 nm process node versus the W7800's 5 nm, and it achieves a higher transistor density of 142.6M per mm² compared to 109.1M per mm².

# Architecture Differences

Both GPUs are built on AMD's RDNA 3.0 architecture, but they diverge sharply in implementation. The Radeon PRO W7800 uses the Navi 31 chip with the codename Plum Bonito, belonging to the Radeon Pro Navi generation. The Ryzen Z2 GPU uses the Hawk Point chip and is classified under Console GPU generation for AMD.

The process nodes differ: the W7800 uses TSMC's 5 nm process, while the Ryzen Z2 GPU uses TSMC's 4 nm process. This explains the transistor density gap, the Ryzen Z2 GPU packs 142.6M transistors per mm² across a 178 mm² die for a total of 25,390 million transistors, while the W7800 spreads 57,700 million transistors across a much larger 529 mm² die at 109.1M per mm².

The compute architectures scale accordingly. The W7800 has 4,480 shading units, 280 texture mapping units, 128 ROPs, and 70 ray tracing cores. The Ryzen Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. That is roughly 5.8x more shading units and 5.8x more ray tracing cores on the workstation part.

Clock behavior also differs significantly. The W7800 has a base clock of 1895 MHz and a boost clock of 2525 MHz. The Ryzen Z2 GPU has a much lower base clock of 800 MHz but a higher boost clock of 2700 MHz. This suggests the Ryzen Z2 GPU is designed to ramp up quickly under load while idling at very low frequencies to conserve power. The W7800 maintains high clocks throughout its operating range.

Memory architecture is a fundamental split. The W7800 uses dedicated GDDR6 memory with a 256-bit interface and a memory clock of 2250 MHz, translating to 18 Gbps effective. The Ryzen Z2 GPU uses LPDDR5X memory at 937 MHz with a 128-bit interface, yielding 7.5 Gbps effective. The memory type difference reflects their respective roles: the W7800 needs maximum bandwidth for professional workloads, while the Ryzen Z2 GPU shares a unified memory pool typical of console and APU designs.

Both support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither part has tensor cores listed, so any AI acceleration claims would come from the shader and ray tracing hardware. The W7800 has a dual-slot cooler and uses 2x 8-pin power connectors with a 600 W suggested PSU. The Ryzen Z2 GPU has no slot width, no power connectors, and no suggested PSU, reinforcing its low-power integrated nature.

# Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Radeon PRO W7800 and the Ryzen Z2 GPU. The wins counters for both sides are zero. However, the individual benchmark results for the W7800 provide a reference point for its performance level.

The W7800 scores 154,366 in Geekbench OpenCL and 175,422 in Geekbench Vulkan. These are strong results that place the card at the 97th percentile of all GPUs. Its average benchmark score of 164,894 puts it in close competition with several NVIDIA workstation parts. The nearest rival is the NVIDIA RTX A5500 with an average score of 165,217, a delta of only -0.2%, meaning the W7800 trails by a negligible margin. The RTX 4500 Ada Generation scores 166,094, putting the W7800 0.7% behind. The AMD Radeon Pro W6900X scores 168,574, which is 2.2% ahead of the W7800. The W7800 leads the NVIDIA A100 PCIe 40 GB, which scores 162,504, by 1.5%.

These rival comparisons bracket the W7800's position. It is essentially on par with the RTX A5500 and RTX 4500 Ada Generation, slightly behind the W6900X, and slightly ahead of the A100 PCIe. The Ryzen Z2 GPU has no comparable data, as it has no benchmark scores and no nearest rivals recorded.

The practical takeaway from the recorded numbers is that the W7800 operates in a performance tier where small percentage differences separate it from its closest competitors. A 0.2% delta against the RTX A5500 is within measurement noise, indicating the two cards are effectively equivalent in aggregate compute performance. The 2.2% gap to the W6900X is also small in absolute terms, though it does place the W7800 at the lower end of its immediate competitive cluster.

# The Verdict

The data presents a clear division of roles. The Radeon PRO W7800 is a professional workstation GPU with 32 GB of GDDR6 memory, 45.25 TFLOPS of FP32 compute, and a 97th percentile ranking. It is designed for tasks that demand sustained throughput, large memory capacity, and high bandwidth. Its nearest rivals, all NVIDIA workstation or datacenter parts, confirm its positioning: it trades fractions of a percent with the RTX A5500 and RTX 4500 Ada Generation, sits 2.2% behind the Radeon Pro W6900X, and runs 1.5% ahead of the A100 PCIe.

The Ryzen Z2 GPU is a different class entirely. Its 8.294 TFLOPS of FP32 compute, 16 GB of LPDDR5X memory, and 28 W TDP place it in the console and embedded segment. It has no recorded benchmarks and no rivals in the database, so its performance cannot be directly compared to the W7800's competition. The architecture shares RDNA 3.0 heritage, but the implementation is scaled down to a 178 mm² die with 768 shading units.

For workloads that require massive compute throughput and professional-grade memory, the Radeon PRO W7800 is the only choice supported by the data. For power-constrained environments where a 28 W envelope matters more than peak performance, the Ryzen Z2 GPU fits that niche. The 5.5x FP32 advantage, 4.8x memory bandwidth advantage, and 4x memory capacity advantage of the W7800 are decisive for any compute-heavy application. The Ryzen Z2 GPU's advantages are its 4 nm process, higher transistor density, lower power draw, and absence of external power requirements.
