AMD Radeon PRO W7900 vs AMD Ryzen Z2 A GPU Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark comparisons between the AMD Radeon PRO W7900 and the AMD Ryzen Z2 A GPU. The headToHeadBenchmarks array is empty, and neither item records a win in any shared test. This absence of overlapping measurement data means any direct performance comparison must be inferred from the individual benchmark scores and architectural specifications recorded for each product.

The AMD Radeon PRO W7900 delivers an average benchmark score of 110,725 across its two recorded tests. Its Geekbench OpenCL result reaches 84,379, while the Geekbench Vulkan score climbs to 137,070. These figures place the W7900 in the 94th percentile when ranked against all GPUs in the database. The Ryzen Z2 A GPU, by contrast, has no recorded benchmark scores at all, carries an average benchmark score of 0, and sits at the 50th percentile, which reflects the median position of a device with no measurement data rather than any actual test result.

The nearest rivals for the W7900 provide useful reference points. The AMD Radeon Pro Vega II posts an average score of 109,617, which is just 1% behind the W7900. The NVIDIA RTX A5500 Mobile records 113,944, putting it 2.8% ahead of the W7900. The AMD Radeon Pro W6600X scores 107,342, trailing the W7900 by 3.2%. The NVIDIA Tesla V100 SXM2 16 GB reaches 114,395, which is 3.2% higher than the W7900's average. These deltas show that the W7900 sits in a tightly contested performance band, with its nearest rivals clustered within roughly three percentage points in either direction.

The Ryzen Z2 A GPU has no nearest rivals listed in the database, which further underscores the lack of comparative measurement data for this product. The W7900's 110,725 average score represents the only concrete performance number available for either device in this comparison.

Architecture Differences

The two GPUs diverge sharply across nearly every architectural parameter recorded in the database. The AMD Radeon PRO W7900 uses the Navi 31 chip built on RDNA 3.0 architecture, with the Plum Bonito codename, and belongs to the Radeon Pro Navi (Navi III Series) generation. The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0 architecture and belongs to the Console GPU (AMD) generation. This places the W7900 one architecture generation ahead of the Ryzen Z2 A GPU.

The fabrication processes differ as well. The W7900 is manufactured on a 5 nm process at TSMC, while the Ryzen Z2 A GPU uses a 7 nm process, also at TSMC. The transistor counts show a massive disparity: the W7900 integrates 57,700 million transistors across a die size of 529 mm², resulting in a transistor density of 109.1 million transistors per square millimeter. The Ryzen Z2 A GPU integrates 2,400 million transistors across a 163 mm² die, producing a transistor density of just 14.7 million per square millimeter. The W7900 carries more than 24 times the transistor count of the Ryzen Z2 A GPU.

Memory configurations also separate the two products. The W7900 comes with 48 GB of GDDR6 memory on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The Ryzen Z2 A GPU offers 16 GB of LPDDR5 memory on a 128-bit bus, with 102.4 GB/s of bandwidth. The W7900 therefore provides three times the memory capacity and more than eight times the memory bandwidth.

The compute resources differ by an order of magnitude. The W7900 has 6,144 shading units, 384 texture mapping units, 192 raster output pipelines, and 96 ray tracing cores. The Ryzen Z2 A GPU has 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. The W7900's shading unit count is exactly 12 times higher, its TMU count is 12 times higher, its ROP count is 12 times higher, and its ray tracing core count is 12 times higher.

Clock speeds and resulting throughput figures reflect these architectural differences. The W7900 runs at a base clock of 1760 MHz and a boost clock of 2495 MHz, with memory clocked at 2250 MHz for 18 Gbps effective. The Ryzen Z2 A GPU runs at a base clock of 1000 MHz and a boost clock of 1600 MHz, with memory clocked at 800 MHz for 6.4 Gbps effective. The pixel rate for the W7900 is 479.0 GPixel/s versus 25.60 GPixel/s for the Ryzen Z2 A GPU. The texture rate for the W7900 is 958.1 GTexel/s versus 51.20 GTexel/s. FP32 throughput reaches 61.32 TFLOPS on the W7900 versus 1.638 TFLOPS on the Ryzen Z2 A GPU. The FP16 figures are 61.32 TFLOPS (1:1) for the W7900 and 3.277 TFLOPS (2:1) for the Ryzen Z2 A GPU.

Power consumption diverges just as dramatically. The W7900 has a TDP of 295 W, requires a triple-slot cooler, uses two 8-pin power connectors, and needs a 600 W suggested power supply. The Ryzen Z2 A GPU has a TDP of 15 W, which is roughly 20 times lower, and the database records no slot width, power connector, or suggested PSU information for it. The W7900 connects via PCIe 4.0 x16, while the Ryzen Z2 A GPU has no bus interface recorded. Display outputs also differ: the W7900 provides three DisplayPort 2.1 ports plus one mini-DisplayPort 2.1, whereas the Ryzen Z2 A GPU offers a single USB Type-C output.

Both products support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The W7900 was released on 2023-05-25, and the Ryzen Z2 A GPU has a release date of 2024-12-31. The W7900 lists a launch MSRP of 3,999 USD, while the Ryzen Z2 A GPU has no launch MSRP recorded. The W7900's predecessor is the Radeon Pro Vega, and the Ryzen Z2 A GPU has no predecessor or successor listed. Both products remain in active production status.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every measurable performance category recorded in the database. Its average benchmark score of 110,725 stands against a score of 0 for the Ryzen Z2 A GPU. The W7900's 94th percentile ranking among all GPUs compares to the 50th percentile for the Ryzen Z2 A GPU. In raw compute terms, the W7900 delivers 61.32 TFLOPS of FP32 performance, which is more than 37 times the 1.638 TFLOPS of the Ryzen Z2 A GPU. The W7900's 48 GB memory capacity, 864.0 GB/s bandwidth, and 384-bit bus provide far more headroom for large datasets and high-resolution textures than the Ryzen Z2 A GPU's 16 GB, 102.4 GB/s, and 128-bit bus.

The Ryzen Z2 A GPU holds no recorded wins in any benchmark or specification category. Its advantages are limited to characteristics that favor low power and compact integration. The 15 W TDP is dramatically lower than the W7900's 295 W TDP, making the Ryzen Z2 A GPU suitable for scenarios where thermal output and power draw are primary constraints. The 7 nm process, while older than the W7900's 5 nm node, still represents a modern fabrication technology. The Ryzen Z2 A GPU's single USB Type-C output suggests a simplified connectivity scheme appropriate for embedded or portable applications, whereas the W7900's multiple DisplayPort outputs target multi-monitor professional workstations.

The W7900's architecture advantage shows in the RDNA 3.0 generation versus RDNA 2.0, the larger die (529 mm² versus 163 mm²), and the substantially higher transistor count (57,700 million versus 2,400 million). These differences translate directly into the 12x advantage in shading units, TMUs, ROPs, and ray tracing cores. For workloads that depend on parallel compute throughput, the W7900's specifications indicate overwhelming superiority. For workloads that prioritize low power consumption and minimal physical footprint, the Ryzen Z2 A GPU's 15 W envelope represents its primary strength.

The Verdict

The database records no direct head-to-head benchmark results between the AMD Radeon PRO W7900 and the AMD Ryzen Z2 A GPU, so the verdict rests on the individual measurements and specifications available. The W7900's average benchmark score of 110,725 places it in the 94th percentile of all GPUs, with nearest rivals within a narrow 3.2% band. The Ryzen Z2 A GPU has no benchmark data, no rivals, and an average score of 0. Anyone selecting between these two products should choose the AMD Radeon PRO W7900 for any workload requiring high compute throughput, large memory capacity, or substantial memory bandwidth. The W7900's 48 GB GDDR6 memory, 864.0 GB/s bandwidth, and 61.32 TFLOPS FP32 performance make it appropriate for professional rendering, simulation, or data-parallel tasks.

The AMD Ryzen Z2 A GPU is appropriate only for scenarios where the 15 W TDP is the deciding factor. Its 1.638 TFLOPS FP32 performance and 102.4 GB/s bandwidth are sufficient for lightweight graphics duties, but the absence of any recorded benchmark scores means its practical performance cannot be verified from the database. The 50th percentile ranking reflects the median position of a device with no measurements, not evidence of competitive performance. The W7900's 295 W TDP and triple-slot cooler make it unsuitable for power-constrained environments, which is where the Ryzen Z2 A GPU's specifications become relevant.
