AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 5090 D Comparison

Head-to-Head Benchmarks

The recorded data in the database contains no direct head-to-head benchmark comparisons between the AMD Ryzen Z2 A GPU and the NVIDIA GeForce RTX 5090 D. The head-to-head benchmark field is empty, and neither item lists wins in a direct comparison. The database instead provides benchmark scores for the RTX 5090 D across multiple tests, while the Ryzen Z2 A GPU carries no benchmark entries at all.

What the data does show is a stark separation in raw compute capability. The RTX 5090 D delivers 104.8 TFLOPS of FP32 performance, while the Ryzen Z2 A GPU delivers 1.638 TFLOPS. That is a 64x difference in single-precision throughput. The RTX 5090 D also reaches 1,636.8 GTexel/s of texture fill rate versus 51.20 GTexel/s for the Ryzen Z2 A GPU, a 32x gap. Pixel throughput similarly diverges: 423.6 GPixel/s versus 25.60 GPixel/s, roughly 16.5x higher on the NVIDIA side.

The RTX 5090 D's benchmark scores in the database illustrate its position. Its 3DMark Steel Nomad DX12 score is 14,326. In Geekbench OpenCL it scores 310,674, and in Geekbench Vulkan it scores 376,915. Passmark results show a G3D score of 44,065, a GPU compute score of 28,396, and a G2D score of 1,487. The average benchmark score across all recorded tests is 77,712, placing the RTX 5090 D in the 92nd percentile of all GPUs in the database.

The nearest rivals listed for the RTX 5090 D put those numbers in context. The AMD Radeon RX 6650M XT has an average score of 76,904, which is 1.1% higher than the RTX 5090 D's average, meaning the RTX 5090 D trails that mobile GPU by a narrow margin. The AMD Radeon RX 6850M XT averages 78,940, 1.6% above the RTX 5090 D. Two NVIDIA Tesla P100 variants also sit nearby: the PCIe 12 GB version averages 79,396 (2.1% higher) and the PCIe 16 GB version averages 79,605 (2.4% higher). These deltas are small, suggesting the RTX 5090 D clusters tightly with a group of capable GPUs rather than dominating them in aggregate benchmark averages.

The Ryzen Z2 A GPU has no nearest rivals listed and no benchmark scores recorded. Its percentile standing of 50 places it at the midpoint of all GPUs in the database, though this figure is not backed by any measured benchmark entries in the pack. The absence of direct comparisons means the database does not support a quantified head-to-head narrative for these two products. The only verifiable conclusion from the recorded data is the enormous raw specification gap and the RTX 5090 D's measured performance profile.

The Verdict

The database provides no direct benchmark comparison between these two GPUs, so any verdict must rest on the recorded specifications and the RTX 5090 D's measured scores. On raw performance metrics, the RTX 5090 D is overwhelmingly ahead. It has 21760 shading units versus 512, 680 TMUs versus 32, 176 ROPs versus 16, and 680 tensor cores versus none listed for the Ryzen Z2 A GPU. Its clock speeds are higher across the board: 2017 MHz base and 2407 MHz boost versus 1000 MHz base and 1600 MHz boost. Memory bandwidth is 1.79 TB/s versus 102.4 GB/s.

The RTX 5090 D's percentile ranking of 92 and average benchmark score of 77,712 confirm it sits in the upper tier of the database. Its nearest rivals, all within 2.4% of its average score, are high-end mobile or datacenter GPUs, which indicates the RTX 5090 D performs in that class. The Ryzen Z2 A GPU, with a 50th percentile standing and no benchmark scores, cannot be positioned against the RTX 5090 D with any measured performance data.

For a user selecting based strictly on the recorded data, the RTX 5090 D is the clear choice for any workload demanding high FP32 throughput, high memory bandwidth, or large VRAM capacity. Its 32 GB GDDR7 memory and 104.8 TFLOPS FP32 output are unmatched in this comparison. The Ryzen Z2 A GPU, with 15 W TDP and 16 GB LPDDR5, occupies a completely different segment. Its data suggests a low-power part suited to constrained environments, not a competitor to the RTX 5090 D. The verdict from the database is unambiguous: these are not comparable products in performance terms, and the RTX 5090 D dominates every measured specification.

Architecture Differences

The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. It is classified in the database as a Console GPU (AMD) generation. The chip contains 2,400 million transistors on a 163 mm² die, giving a transistor density of 14.7M per mm². Its FP16 output is listed as 3.277 TFLOPS with a 2:1 ratio, meaning FP16 throughput is double FP32, a common configuration for RDNA 2 parts. The GPU has no tensor cores listed, no bus interface specified, and no power connector details.

The NVIDIA GeForce RTX 5090 D uses the GB202 chip built on Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. It belongs to the GeForce 50-series and the GeForce 50 generation. The chip contains 92,200 million transistors on a 750 mm² die, giving a transistor density of 122.9M per mm². FP16 performance is 104.8 TFLOPS with a 1:1 ratio, meaning FP16 and FP32 throughput are equal, a design choice that differs from the Ryzen Z2 A GPU's 2:1 scheme. The RTX 5090 D includes 680 tensor cores, a feature absent from the AMD part's specifications. It also carries a PCIe 5.0 x16 bus interface and a 16-pin power connector, neither of which is listed for the Ryzen Z2 A GPU.

The transistor count difference is enormous: 92,200 million versus 2,400 million, a 38x gap. Die size differs by 4.6x (750 mm² versus 163 mm²). Transistor density on the NVIDIA chip is 8.4x higher (122.9M per mm² versus 14.7M per mm²), reflecting the denser 5 nm process. The RTX 5090 D's memory subsystem is also architecturally distinct: GDDR7 on a 512-bit bus versus LPDDR5 on a 128-bit bus. The release dates differ as well, with the Ryzen Z2 A GPU listed as released on 2024-12-31 and the RTX 5090 D on 2025-01-29. Both are marked as Active in production status. The RTX 5090 D lists a predecessor (GeForce 40) and successor (GeForce 60), while the Ryzen Z2 A GPU lists neither.
