AMD Radeon PRO W7800 vs AMD Radeon RX 9050 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two AMD workstation and consumer GPUs. The AMD Radeon PRO W7800 delivers an average benchmark score of 164,894, placing it in the 97th percentile of all GPUs in the database. The AMD Radeon RX 9050, by contrast, has no recorded benchmark scores, an average score of 0, and sits in the 50th percentile. This means the PRO W7800 outperforms the RX 9050 in every measurable category, with the gap spanning compute throughput, memory bandwidth, and rendering rates.

In raw compute, the Radeon PRO W7800 delivers 45.25 TFLOPS of FP32 performance and 90.50 TFLOPS of FP16 performance using a 2:1 ratio. The Radeon RX 9050 provides 10.65 TFLOPS in both FP32 and FP16, with a 1:1 ratio. The PRO W7800 therefore offers more than four times the FP32 throughput. The FP16 comparison is even more lopsided: the PRO W7800 reaches 90.50 TFLOPS versus 10.65 TFLOPS on the RX 9050, an advantage of roughly 8.5 times. Pixel fill rates follow the same pattern, with the PRO W7800 at 323.2 GPixel/s against 166.4 GPixel/s on the RX 9050. Texture fill rates show the largest relative gap, 707.0 GTexel/s versus 166.4 GTexel/s, a difference of approximately 4.25 times.

Memory capacity and bandwidth further separate the two. The Radeon PRO W7800 carries 32 GB of GDDR6 memory on a 256-bit bus, producing 576.0 GB/s of bandwidth. The Radeon RX 9050 has 8 GB of GDDR6 on a 128-bit bus, yielding 288.0 GB/s. The PRO W7800 offers four times the memory capacity and exactly double the memory bandwidth. The RX 9050 cannot compensate through clock speed alone; its boost clock of 2600 MHz is only 75 MHz higher than the PRO W7800's 2525 MHz boost. The PRO W7800 also has a substantially higher base clock at 1895 MHz versus 1330 MHz on the RX 9050.

In the database's nearest-rival comparisons, the PRO W7800 trades nearly evenly with professional NVIDIA cards. It sits 0.2% behind the NVIDIA RTX A5500, 0.7% behind the NVIDIA RTX 4500 Ada Generation, 1.5% ahead of the NVIDIA A100 PCIe 40 GB, and 2.2% behind the AMD Radeon Pro W6900X. These margins are small, confirming that the PRO W7800 operates in a professional tier where single-digit percentage differences separate competing workstation GPUs. The RX 9050 has no nearest rivals recorded, leaving its competitive positioning undefined in the database.

Where Each One Wins

The Radeon PRO W7800 wins in every benchmark category for which data exists. It holds advantages in FP32 compute, FP16 compute, pixel rate, texture rate, memory capacity, and memory bandwidth. The only area where the RX 9050 posts a higher number is boost clock frequency, 2600 MHz versus 2525 MHz, but this does not translate into a single performance win because the PRO W7800 compensates with far more execution units: 4480 shading units, 280 texture mapping units, and 128 render output units against 1024 shading units, 64 TMUs, and 64 ROPs on the RX 9050.

The RX 9050 wins on power efficiency in raw terms, with a 92 W TDP versus 260 W on the PRO W7800. The suggested power supply for the RX 9050 is 250 W, compared to 600 W for the PRO W7800. The RX 9050 also requires only a single 8-pin power connector, while the PRO W7800 needs two 8-pin connectors. These figures indicate that the RX 9050 is designed for systems with modest power budgets, while the PRO W7800 targets workstations with robust power delivery. The RX 9050 also carries a newer PCIe interface, PCIe 5.0 x16 versus PCIe 4.0 x16 on the PRO W7800, which may matter for data transfer in systems that support it.

Use-case separation follows the specification splits. The PRO W7800 suits workloads that demand large memory pools, such as rendering scenes that exceed 8 GB, or compute tasks with high FP32 and FP16 throughput. The RX 9050 suits tasks where 8 GB of memory and 10.65 TFLOPS suffice, and where the 92 W power draw is a constraint. The RX 9050's RT core count of 16 versus 70 on the PRO W7800 indicates a substantial difference in ray tracing throughput, with the PRO W7800 holding a clear edge.

Architecture Differences

The two GPUs belong to different RDNA generations. The Radeon PRO W7800 uses the RDNA 3.0 architecture with the Navi 31 chip and the codename Plum Bonito. Its generation is listed as Radeon Pro Navi (Navi III Series). The Radeon RX 9050 uses RDNA 4.0 with the Navi 44 chip and belongs to the Navi IV (RX 9000) generation. The predecessor of the RX 9050 is listed as Navi III, which places it as a direct successor to the architecture family that the PRO W7800 represents.

Manufacturing processes differ. The PRO W7800 is built on TSMC's 5 nm process, while the RX 9050 uses a 4 nm process from the same foundry. The newer node allows the RX 9050 to achieve a higher transistor density of 149.2 million transistors per square millimeter, compared to 109.1 million on the PRO W7800. The RX 9050 packs 29,700 million transistors into a 199 mm² die. The PRO W7800 contains 57,700 million transistors across a 529 mm² die. The PRO W7800's die is approximately 2.66 times larger and holds roughly 1.94 times more transistors.

Ray tracing hardware differs sharply. The PRO W7800 includes 70 RT cores, while the RX 9050 has 16. Neither GPU includes tensor cores, so both rely on standard shader and RT hardware. The FP16 execution model also differs: the PRO W7800 achieves 90.50 TFLOPS through a 2:1 ratio, meaning it doubles FP16 throughput relative to FP32, while the RX 9050 runs FP16 at a 1:1 ratio, matching its FP32 rate of 10.65 TFLOPS. This architectural choice gives the PRO W7800 a much larger advantage in FP16 workloads than in FP32 ones.

The PRO W7800 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 9050 supports the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. No API-level differences exist between the two in the recorded data.

The Verdict

The data directs different buyers to each card. The Radeon PRO W7800 is the choice for workloads that need maximum compute throughput, large memory capacity, and high bandwidth. Its 32 GB of GDDR6, 576.0 GB/s bandwidth, 45.25 TFLOPS FP32, and 70 RT cores place it in the 97th percentile of all GPUs in the database. It trades within 2.2% of several NVIDIA professional cards, including the RTX A5500, RTX 4500 Ada Generation, and A100 PCIe 40 GB, confirming its position in the professional segment. The 2,499 USD launch MSRP reflects that positioning.

The Radeon RX 9050 suits systems where 92 W power draw and a 250 W PSU are required. Its 8 GB memory and 10.65 TFLOPS FP32 throughput place it in the 50th percentile, with no benchmark scores recorded. The RX 9050 has the newer PCIe 5.0 x16 interface and a 4 nm process with higher transistor density, but these do not offset the PRO W7800's overwhelming advantages in shading units, TMUs, ROPs, RT cores, memory, and fill rates. The RX 9050 has no nearest rivals in the database, so its competitive standing is unmeasured.

For professional rendering, simulation, or compute workloads, the Radeon PRO W7800 is the only defensible choice given the recorded specifications. For low-power consumer use with modest memory needs, the Radeon RX 9050 fits that narrower profile. The benchmark data provides no scenario where the RX 9050 outperforms the PRO W7800.
