AMD Radeon PRO W7900D vs AMD Ryzen Z2 GPU Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark comparisons between the AMD Radeon PRO W7900D and the AMD Ryzen Z2 GPU. The head-to-head benchmark array is empty, and neither part has an average benchmark score or a competitive percentile ranking above the neutral 50th percentile baseline. This means the quantitative comparison must be built from the specification-level data in the database rather than from executed test workloads.

The raw compute figures establish the scale of the gap. The Radeon PRO W7900D delivers 52.99 TFLOPS of FP32 throughput, while the Ryzen Z2 GPU delivers 8.294 TFLOPS. That is a 6.39x difference in raw single-precision compute. In FP16, both parts operate at a 1:1 ratio with their FP32 figures, so the same 52.99 TFLOPS versus 8.294 TFLOPS split applies. The texture rate tells a similar story: the W7900D reaches 827.9 GTexel/s, while the Ryzen Z2 GPU reaches 129.6 GTexel/s, a 6.39x advantage for the larger part. Pixel throughput is 414.0 GPixel/s on the W7900D versus 86.40 GPixel/s on the Ryzen Z2 GPU, a 4.79x difference.

Memory bandwidth is another major separation point. The W7900D uses a 384 bit GDDR6 interface running at 2250 MHz (18 Gbps effective), producing 864.0 GB/s. The Ryzen Z2 GPU uses a 128 bit LPDDR5X interface running at 937 MHz (7.5 Gbps effective), producing 119.9 GB/s. The W7900D has 7.21x the memory bandwidth. That bandwidth advantage matters for any workload that streams large datasets, which is the typical profile for the workstation-oriented W7900D.

The shader configuration reinforces the compute gap. The W7900D has 6144 shading units, 384 texture mapping units, 192 render output units, and 96 ray accelerators. The Ryzen Z2 GPU has 768 shading units, 48 texture mapping units, 32 render output units, and 12 ray accelerators. The W7900D carries 8x the shading units, 8x the TMUs, 6x the ROPs, and 8x the ray accelerators. These are not close specifications by any measure.

Clock behavior offers the only area where the smaller part shows a relative strength. The Ryzen Z2 GPU has a boost clock of 2700 MHz, which is 544 MHz higher than the W7900D's 2156 MHz boost. Its base clock of 800 MHz is lower than the W7900D's 1327 MHz base, but the boost ceiling is clearly higher. The Ryzen Z2 GPU is designed to reach a higher frequency under load, though that does little to close the enormous gap in execution resources and memory bandwidth.

Where Each One Wins

The Radeon PRO W7900D wins in every throughput-oriented category. Its 48 GB of GDDR6 memory dwarfs the 16 GB of LPDDR5X on the Ryzen Z2 GPU. For GPU compute tasks that fit within memory capacity, the W7900D can hold three times as much working data. The 864.0 GB/s bandwidth is more than seven times the 119.9 GB/s of the Ryzen Z2 GPU, which is the decisive factor for memory-bound workloads. The W7900D also has the advantage of a 384 bit bus versus 128 bit, which explains the bandwidth gap even before considering the memory type difference.

The W7900D is a triple-slot card with dual 8-pin power connectors and a 295 W TDP. The Ryzen Z2 GPU has a 28 W TDP, no power connectors, and a single USB Type-C display output. The W7900D requires a 600 W suggested power supply, while the Ryzen Z2 GPU has no suggested PSU figure recorded. These are fundamentally different product categories despite sharing the RDNA 3.0 architecture name.

The Ryzen Z2 GPU wins on integration and power envelope. At 28 W, it consumes roughly one tenth of the power of the W7900D. It is a console-class GPU with no slot width recorded, no dimensions recorded, and no power connectors. It fits into compact designs where the W7900D's 280 mm length, 110 mm height, and 51 mm width would not be viable. The Ryzen Z2 GPU also has a smaller die at 178 mm² versus 529 mm², and it uses a 4 nm process node compared to the W7900D's 5 nm node. That process advantage contributes to its higher boost clock of 2700 MHz.

The W7900D offers three DisplayPort 2.1 outputs plus one mini-DisplayPort 2.1 output, while the Ryzen Z2 GPU offers a single USB Type-C output. For multi-display workstation setups, the W7900D has a clear connectivity advantage. For embedded or handheld designs, the single USB Type-C output of the Ryzen Z2 GPU is simpler and matches its low-power profile.

The W7900D belongs to the Radeon Pro Navi (Navi III Series) generation, while the Ryzen Z2 GPU belongs to the Console GPU (AMD) generation.

Process node and die size differ significantly. The W7900D is built on a 5 nm TSMC process with 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1M per mm². The Ryzen Z2 GPU is built on a 4 nm TSMC process with 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6M per mm². The Ryzen Z2 GPU achieves higher transistor density despite having fewer total transistors.

Clock specifications differ in both base and boost. The W7900D runs at 1327 MHz base and 2156 MHz boost, with memory at 2250 MHz (18 Gbps effective). The Ryzen Z2 GPU runs at 800 MHz base and 2700 MHz boost, with memory at 937 MHz (7.5 Gbps effective).

Memory configuration is a major differentiator. The W7900D has 48 GB of GDDR6 on a 384 bit bus with 864.0 GB/s bandwidth. The Ryzen Z2 GPU has 16 GB of LPDDR5X on a 128 bit bus with 119.9 GB/s bandwidth.

Compute unit counts differ by an order of magnitude. The W7900D has 6144 shading units, 384 TMUs, 192 ROPs, and 96 ray accelerators. The Ryzen Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray accelerators.

The physical specifications show the W7900D is a triple-slot card measuring 280 mm in length, 110 mm in height, and 51 mm in width. The Ryzen Z2 GPU has no slot width, length, height, or width recorded. The W7900D uses two 8-pin power connectors and requires a 600 W suggested PSU. The Ryzen Z2 GPU has no power connectors and no suggested PSU.

The W7900D uses a PCIe 4.0 x16 bus interface, while the Ryzen Z2 GPU has no bus interface recorded. The W7900D has 295 W TDP, while the Ryzen Z2 GPU has 28 W TDP. Both parts share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both parts have no tensor cores recorded. The W7900D has a predecessor listed as Radeon Pro Vega, while the Ryzen Z2 GPU has no predecessor recorded. Neither has a successor.

Architecture Differences

Both GPUs use RDNA 3.0 architecture, but the implementation details diverge sharply. The W7900D uses the Navi 31 chip, which is a large discrete GPU die designed for workstation workloads. The Ryzen Z2 GPU uses the Hawk Point chip, which is a smaller integrated-class design aimed at console applications.

The process node differs by one generation step. The W7900D uses 5 nm TSMC, while the Ryzen Z2 GPU uses 4 nm TSMC. The smaller node on the Ryzen Z2 GPU explains its higher transistor density of 142.6M per mm² versus 109.1M per mm² for the W7900D. Despite the density advantage, the Ryzen Z2 GPU has far fewer total transistors: 25,390 million versus 57,700 million.

Die size tells the story of design intent. The W7900D's 529 mm² die is nearly three times larger than the Ryzen Z2 GPU's 178 mm² die. The larger die accommodates 8x the shading units, 8x the TMUs, 6x the ROPs, and 8x the ray accelerators. That massive resource allocation is what enables the W7900D's 52.99 TFLOPS FP32 figure.

The memory architecture differs in type and width. The W7900D uses GDDR6, a discrete memory standard with a 384 bit interface. The Ryzen Z2 GPU uses LPDDR5X, a low-power memory standard with a 128 bit interface. LPDDR5X typically integrates closer to the processor package, which suits the Ryzen Z2 GPU's low-power console role. GDDR6 with a wide bus suits the W7900D's high-bandwidth workstation role.

Ray tracing resources differ substantially. The W7900D has 96 ray accelerators, while the Ryzen Z2 GPU has 12. That 8x difference in ray accelerator count aligns with the overall shader resource ratio. For ray-traced workloads, the W7900D has a structural advantage built into its silicon.

Power architecture reflects the different roles. The W7900D is a discrete add-in card with a 295 W TDP, two 8-pin power connectors, and a 600 W suggested PSU. The Ryzen Z2 GPU is a 28 W part with no power connectors, designed to be powered through its host system. The W7900D's power delivery infrastructure supports sustained high-throughput compute, while the Ryzen Z2 GPU's minimal power draw enables compact, low-heat designs.

The display output architecture also differs. The W7900D has three DisplayPort 2.1 outputs and one mini-DisplayPort 2.1 output, suitable for multi-monitor professional setups. The Ryzen Z2 GPU has a single USB Type-C output, which fits its console-oriented single-display use case.

The Verdict

The database records no shared benchmark results, so the verdict rests on the specification-level data. The AMD Radeon PRO W7900D is designed for compute-heavy workstation workloads. Its 48 GB GDDR6 memory, 864.0 GB/s bandwidth, 52.99 TFLOPS FP32, and 96 ray accelerators position it as a high-throughput GPU for tasks that need large memory capacity and sustained parallel compute. The 295 W TDP and triple-slot cooler are the physical cost of that capability.

The AMD Ryzen Z2 GPU is designed for power-constrained console or embedded applications. Its 28 W TDP, lack of power connectors, and single USB Type-C output indicate a part that slots into a fixed platform rather than a user-upgradeable desktop card. Its 8.294 TFLOPS FP32 and 119.9 GB/s bandwidth are modest figures, but its 2700 MHz boost clock and 4 nm process node show an emphasis on efficiency within a small power envelope.

The choice between these two is determined by the target platform. The W7900D suits a workstation with a 600 W PSU, multiple DisplayPort displays, and workloads that can use 48 GB of memory. The Ryzen Z2 GPU suits a compact device with no add-in card slot, no discrete power connectors, and a single display output. Neither part is a substitute for the other; they occupy different segments of the AMD product stack. The W7900D is active with a 2025 release date, while the Ryzen Z2 GPU is active with a 2024 release date. The data does not support any crossover use case.
