Architecture Differences

The AMD Ryzen Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, classified under the generation "Console GPU (AMD)". The NVIDIA GeForce RTX 4090 D uses the AD102 chip with Ada Lovelace architecture, classified under the generation "GeForce 40". The AMD part is fabricated on a 7 nm process, while the NVIDIA part uses a 5 nm process. Both are from TSMC.

The NVIDIA architecture includes tensor cores, which are entirely absent from the AMD part's recorded specification. The RTX 4090 D has 456 tensor cores, which are used for AI workloads. The AMD part has no tensor core count, no tensor core field, and no equivalent feature listed. Ray tracing cores differ significantly: 8 on the AMD part versus 114 on the NVIDIA part. The FP16 ratio differs as well: the AMD part uses a 2:1 ratio, meaning FP16 throughput is half of FP32, while the NVIDIA part uses a 1:1 ratio, meaning FP16 throughput equals FP32.

The memory architecture is fundamentally different. LPDDR5 is a low-power memory type typically integrated on-package for compact devices, while GDDR6X is a high-bandwidth discrete memory designed for dedicated graphics cards. The bus width difference (128 bit versus 384 bit) and bandwidth difference (102.4 GB/s versus 1.01 TB/s) reflect the different design goals. The AMD part has no bus interface recorded, suggesting a soldered or embedded design, while the NVIDIA part uses PCIe 4.0 x16.

The display output difference also reflects the design intent. A single USB Type-C port on the AMD part indicates a minimal output configuration, likely for a portable device. The NVIDIA part has one HDMI 2.1 and three DisplayPort 1.4a outputs, typical for a desktop flagship. The NVIDIA part is 304 mm long, 137 mm tall, and 61 mm wide, and it uses a triple-slot cooler with a single 16-pin power connector. The AMD part has no physical dimensions recorded.

The transistor density difference is notable: 14.7M per mm² for the AMD part versus 125.3M per mm² for the NVIDIA part. This reflects both the process node difference and the architectural complexity. The NVIDIA part packs 76,300 million transistors into 609 mm², while the AMD part packs 2,400 million into 163 mm².

The Verdict

The data shows two GPUs built for entirely different purposes. The AMD Ryzen Z2 A GPU, with a 15 W TDP, 1.638 TFLOPS FP32, and 102.4 GB/s memory bandwidth, is designed for low-power, compact systems. Its 16 GB of LPDDR5 memory and single USB Type-C output suggest an integrated or embedded deployment where power draw is the primary constraint. Its 50th percentile ranking places it in the middle of the database's GPU distribution, but without any benchmark scores, its actual performance in standardized tests is unmeasured.

The NVIDIA GeForce RTX 4090 D, with a 425 W TDP, 73.54 TFLOPS FP32, and 1.01 TB/s memory bandwidth, is a high-end desktop GPU aimed at maximum performance. Its 98th percentile ranking and average benchmark score of 178050 place it near the top of the database, just behind four rivals that are within 5% of its score. The recorded benchmarks show strong DirectX 12, OpenCL, and Vulkan performance, with the Vulkan score (246941) lower than OpenCL (278621) but still substantial.

The specification gap is enormous. The RTX 4090 D has 28.5 times more shading units, 14.25 times more TMUs, 11 times more ROPs, 14.25 times more ray tracing cores, and 456 tensor cores where the AMD part has none. Its FP32 performance is 44.9 times higher, and its memory bandwidth is 9.9 times higher. The RTX 4090 D is also physically larger, uses a triple-slot cooler, and requires an 800 W PSU, while the AMD part has no such requirements.

The RTX 4090 D is end-of-life, while the Ryzen Z2 A GPU is still active. The RTX 4090 D has a launch MSRP of 1,599 USD, while the AMD part has no launch MSRP recorded. The release dates are close, with the AMD part launching on 2024-12-31 and the NVIDIA part on 2023-12-27.

For users who need maximum compute throughput, ray tracing performance, or AI acceleration via tensor cores, the RTX 4090 D is the only choice in this comparison. Its benchmark data confirms it operates in the top tier of GPUs. For users who need minimal power consumption, a compact footprint, or integration into a low-power device, the Ryzen Z2 A GPU is the only option, but its lack of recorded benchmark data leaves its actual performance unverified. The database records no head-to-head test between them, so any direct performance comparison relies on the specification sheet, which overwhelmingly favors the NVIDIA part.
