AMD Radeon PRO W7800 vs AMD Ryzen Z2 Go GPU Comparison

The AMD Radeon PRO W7800 and the AMD Ryzen Z2 Go GPU occupy entirely different segments of the graphics market, and the recorded data confirms a massive performance gulf between them. The W7800 is a professional workstation card built on the RDNA 3.0 architecture with a 5 nm process, while the Z2 Go GPU is a low-power console-class part based on RDNA 2.0 on a 6 nm node. The database shows the W7800 delivering an average benchmark score of 164,894 against the Z2 Go GPU's recorded average of 0, which reflects the absence of benchmark entries for the latter rather than a literal zero-performance result. The W7800 also sits at the 97th percentile among all GPUs, whereas the Z2 Go GPU sits at the 50th percentile.

Head-to-Head Benchmarks

The direct benchmark comparison is one-sided because the database contains no head-to-head test entries and no wins recorded for either part. However, the available individual benchmarks for the W7800 illustrate its capability. In Geekbench OpenCL, the W7800 scores 154,366, and in Geekbench Vulkan, it scores 175,422. The Z2 Go GPU has no benchmark scores recorded in any test, so no exact comparison of its compute performance can be drawn from the data. The average benchmark score for the W7800 is 164,894, which places it 0.2 percent below the NVIDIA RTX A5500's average of 165,217, 0.7 percent below the NVIDIA RTX 4500 Ada Generation's average of 166,094, 1.5 percent above the NVIDIA A100 PCIe 40 GB's average of 162,504, and 2.2 percent below the AMD Radeon Pro W6900X's average of 168,574. These delta values place the W7800 in a tightly contested performance tier among professional GPUs.

The Z2 Go GPU, by contrast, has no rivals listed and no average score to compare. Its percentile ranking of 50 indicates it sits at the midpoint of the database's GPU distribution, but the absence of benchmark data means the recorded figures do not quantify its raw throughput. The W7800's FP32 compute is listed at 45.25 TFLOPS, while the Z2 Go GPU lists 4.147 TFLOPS. That is a difference of roughly 10.9 times in favor of the W7800 based on the recorded specifications. Similarly, the texture rate for the W7800 is 707.0 GTexel/s versus 129.6 GTexel/s for the Z2 Go GPU, and the pixel rate is 323.2 GPixel/s versus 86.40 GPixel/s. These specification-derived deltas confirm that the W7800 leads decisively in every raw throughput category where both parts have recorded values.

Memory bandwidth also separates the two clearly. The W7800 uses 32 GB of GDDR6 on a 256 bit bus, delivering 576.0 GB/s. The Z2 Go GPU uses 16 GB of LPDDR5 on a 128 bit bus, delivering 102.4 GB/s. That is a 5.6 times bandwidth advantage for the W7800. The shading unit count reinforces the gap: 4,480 shading units on the W7800 versus 768 on the Z2 Go GPU. The W7800 also has 280 texture mapping units and 128 raster operation units, while the Z2 Go GPU has 48 and 32, respectively. Ray tracing cores number 70 on the W7800 versus 12 on the Z2 Go GPU.

Where Each One Wins

The W7800 wins in every measured performance category where both parts have data. Its FP32 throughput of 45.25 TFLOPS is suited for large compute workloads, and its 576.0 GB/s memory bandwidth supports data-intensive tasks such as high-resolution rendering and complex simulation. The 32 GB memory capacity doubles the Z2 Go GPU's 16 GB, which matters for datasets that exceed a smaller frame buffer. The W7800's 97th percentile ranking among all GPUs indicates it belongs to the upper tier of graphics hardware, while the Z2 Go GPU's 50th percentile places it in the middle of the distribution.

The Z2 Go GPU wins on power efficiency and physical footprint. Its TDP is 28 W, compared to the W7800's 260 W, a difference of 232 W. The Z2 Go GPU requires no power connectors, while the W7800 needs two 8-pin connectors and a suggested 600 W power supply. The Z2 Go GPU also uses a 6 nm process node, whereas the W7800 uses a 5 nm node, but the Z2 Go GPU integrates 13,100 million transistors on a 208 mm² die, giving a transistor density of 63.0M per mm². The W7800 integrates 57,700 million transistors on a 529 mm² die, giving a density of 109.1M per mm². The Z2 Go GPU's lower transistor count and smaller die contribute to its reduced power draw. The Z2 Go GPU also has a boost clock of 2700 MHz, which is higher than the W7800's 2525 MHz boost, though the W7800 has a higher base clock of 1895 MHz versus 800 MHz.

For use cases that demand maximum compute, the W7800 is the clear choice based on the recorded figures. For embedded or low-power applications where a 28 W envelope is required, the Z2 Go GPU fits that role, as its single USB Type-C display output and lack of power connectors indicate a compact integration. The W7800 offers three DisplayPort 2.1 outputs and one mini-DisplayPort 2.1 output, so multi-display professional setups favor it.

Architecture Differences

The W7800 is built on the RDNA 3.0 architecture with the Navi 31 chip and the codename Plum Bonito. The Z2 Go GPU uses the RDNA 2.0 architecture with the Rembrandt+ chip and has no codename listed. The W7800 belongs to the Radeon Pro Navi generation, classified as Navi III Series, while the Z2 Go GPU belongs to the Console GPU generation. The process nodes differ: the W7800 uses TSMC's 5 nm process, and the Z2 Go GPU uses TSMC's 6 nm process. Both parts are fabricated by TSMC.

Transistor counts differ substantially. The W7800 packs 57,700 million transistors, while the Z2 Go GPU has 13,100 million. Die size also differs: 529 mm² for the W7800 versus 208 mm² for the Z2 Go GPU. Transistor density is 109.1M per mm² for the W7800 and 63.0M per mm² for the Z2 Go GPU. The W7800's memory subsystem uses GDDR6 across a 256 bit bus, while the Z2 Go GPU uses LPDDR5 across a 128 bit bus. The W7800's memory clock is listed at 2250 MHz with 18 Gbps effective, while the Z2 Go GPU's memory clock is 800 MHz with 6.4 Gbps effective.

Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The W7800 has 70 ray tracing cores, and the Z2 Go GPU has 12. Neither part lists tensor cores. The W7800's FP16 performance is 90.50 TFLOPS with a 2:1 ratio, and the Z2 Go GPU's FP16 is 8.294 TFLOPS with a 2:1 ratio.

The Verdict

The data identifies the AMD Radeon PRO W7800 as the higher-performing part by a wide margin. Its FP32 compute of 45.25 TFLOPS, memory bandwidth of 576.0 GB/s, and 32 GB frame buffer make it suitable for professional rendering, simulation, and compute workloads. Its percentile ranking of 97 confirms that it sits near the top of the database's GPU distribution. The Z2 Go GPU, with 4.147 TFLOPS FP32, 102.4 GB/s bandwidth, and 16 GB memory, cannot match those figures. For any workload that depends on raw throughput, memory capacity, or bandwidth, the W7800 is the appropriate selection.

The Z2 Go GPU serves a different purpose. Its 28 W TDP, lack of power connectors, and single USB Type-C output indicate a low-power integrated solution. The 50th percentile ranking shows it is an average performer in the broader GPU landscape, and its 768 shading units and 12 ray tracing cores are modest compared to the W7800's 4,480 and 70. For systems constrained by power or space, the Z2 Go GPU fits that role, but the recorded data shows no performance category where it exceeds the W7800.

The release dates differ as well. The W7800 launched on April 12, 2023, with a launch MSRP of 2,499 USD. The Z2 Go GPU launched on December 31, 2024, and has no launch MSRP listed. The W7800's predecessor is the Radeon Pro Vega, while the Z2 Go GPU has no predecessor listed. Both parts are marked as Active in production status.
