Analysis: AMD Ryzen Z2 GPU vs NVIDIA RTX PRO 4500 Blackwell
The Verdict
The recorded data positions these two GPUs at opposite ends of the performance spectrum. The AMD Ryzen Z2 GPU is a 28 W console-class part built on RDNA 3.0, while the NVIDIA RTX PRO 4500 Blackwell is a 200 W professional workstation accelerator. Benchmark results indicate the RTX PRO 4500 is the clear choice for demanding compute and rendering workloads, with an average benchmark score of 31532 versus zero recorded benchmarks for the Ryzen Z2 GPU. The NVIDIA part sits at the 76th percentile among all GPUs in the database, while the AMD part sits at the 50th percentile with no average score recorded.
The Ryzen Z2 GPU targets low-power, integrated-style deployments where the 28 W envelope and 16 GB of LPDDR5X memory are sufficient. The RTX PRO 4500 Blackwell targets professional environments requiring 32 GB of GDDR7 memory, 896.0 GB/s of bandwidth, and 50.53 TFLOPS of FP32 compute. Users needing PCIe 5.0 x16 connectivity, dual-slot cooling, and four DisplayPort 2.1b outputs should choose the NVIDIA card. The AMD part offers a single USB Type-C output and no power connectors, indicating a board-integrated or low-profile design. The data clearly separates these products: the RTX PRO 4500 is for heavy workstation workloads, the Ryzen Z2 GPU is for constrained, low-power systems.
Architecture Differences
The AMD Ryzen Z2 GPU uses the Hawk Point chip built on TSMC's 4 nm process. It implements the RDNA 3.0 architecture and integrates 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6M per mm². The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip on TSMC's 5 nm process, with 45,600 million transistors on a 378 mm² die, giving a lower transistor density of 120.6M per mm². The NVIDIA chip is physically larger and packs nearly twice the transistor count.
The AMD GPU features 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The NVIDIA GPU features 10,496 shading units, 328 TMUs, 112 ROPs, and 82 ray tracing cores. NVIDIA also integrates 328 tensor cores, while the AMD part lists no tensor core count. The NVIDIA card supports PCIe 5.0 x16, while the AMD part has no bus interface listed. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
Memory architecture differs substantially. The Ryzen Z2 GPU uses 16 GB of LPDDR5X on a 128 bit bus, delivering 119.9 GB/s of bandwidth. The RTX PRO 4500 uses 32 GB of GDDR7 on a 256 bit bus, delivering 896.0 GB/s, roughly 7.5 times the bandwidth. Clock behavior also diverges: the AMD part has an 800 MHz base and 2700 MHz boost, while the NVIDIA card has a 1635 MHz base and 2407 MHz boost. Despite the lower boost clock, the NVIDIA card achieves far higher throughput due to its massive shader count.

These deltas show the RTX PRO 4500 sits within roughly one percent of each rival's average score, indicating very close performance clustering at this tier.
The gap between the two reviewed GPUs is enormous in every measured category. The NVIDIA card delivers 6.1 times the FP32 compute, 7.5 times the memory bandwidth, 6.8 times the TMUs, 3.5 times the ROPs, and 6.8 times the ray tracing cores. The AMD part counters with a 4 nm process, higher transistor density, a lower 28 W TDP, and no external power requirement. The AMD GPU's boost clock of 2700 MHz exceeds the NVIDIA boost clock of 2407 MHz, but the shader count difference overwhelms that clock advantage. The RTX PRO 4500's pixel rate of 269.6 GPixel/s is 3.1 times the AMD part's 86.40 GPixel/s, and its texture rate of 789.5 GTexel/s is 6.1 times the AMD's 129.6 GTexel/s. These figures confirm the NVIDIA card as the dominant performer in rasterization throughput, compute, and memory-bound workloads.
