AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 5090 D Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark results for the AMD Ryzen Z2 GPU and the NVIDIA GeForce RTX 5090 D. The Ryzen Z2 GPU has no recorded benchmark scores or average score, while the RTX 5090 D carries a substantial set of measurements. This asymmetry means a direct score-by-score comparison is impossible from the recorded data.

What the data does show is the RTX 5090 D's position relative to its own nearest rivals. Its average benchmark score is 77,712. That places it 1.1% ahead of the AMD Radeon RX 6650M XT (76,904), 1.6% behind the AMD Radeon RX 6850M XT (78,940), 2.1% behind the NVIDIA Tesla P100 PCIe 12 GB (79,396), and 2.4% behind the NVIDIA Tesla P100 PCIe 16 GB (79,605). The percentile ranking for the RTX 5090 D is 92, meaning it outperforms 92% of all GPUs in the database.

Individual benchmark results for the RTX 5090 D show its strongest showing in Geekbench Vulkan with a score of 376,915, and Geekbench OpenCL at 310,674. In Passmark tests, the G3D score is 44,065, while GPU compute reaches 28,396. The DirectX 9 score is 434, DirectX 11 is 371, DirectX 10 is 231, and DirectX 12 is 219. The G2D score is 1,487. A separate 3DMark Steel Nomad DX12 run produced a score of 14,326.

Because the Ryzen Z2 GPU has no benchmark entries, the database records zero wins for either side in head-to-head comparisons. The RTX 5090 D's performance data stands alone, and the Ryzen Z2 GPU's capabilities must be inferred from its specifications rather than measured results.

Architecture Differences

The two chips come from different architectural generations and fundamentally different design goals. The AMD Ryzen Z2 GPU uses the Hawk Point chip with RDNA 3.0 architecture, built on a 4 nm TSMC process. It packs 25,390 million transistors into a 178 mm² die, giving a transistor density of 142.6 million per mm². The RTX 5090 D uses the GB202 chip with Blackwell 2.0 architecture, fabricated on a 5 nm TSMC process. Its die is far larger at 750 mm² and contains 92,200 million transistors, though the density is lower at 122.9 million per mm².

The compute resources differ by an order of magnitude. The Ryzen Z2 GPU has 768 shading units, 48 texture mapping units, and 32 raster output units. It includes 12 ray tracing cores but no tensor cores. The RTX 5090 D has 21,760 shading units, 680 TMUs, and 176 ROPs. It carries 170 ray tracing cores and 680 tensor cores, which enable the AI acceleration features common to Blackwell parts.

Clock speeds tell a similar story. The Ryzen Z2 GPU runs at a base of 800 MHz with a boost of 2700 MHz. The RTX 5090 D has a higher base clock at 2017 MHz but a slightly lower boost at 2407 MHz. Despite the lower boost clock, the massive shader count gives the RTX 5090 D overwhelming throughput. Its FP32 performance is 104.8 TFLOPS, and FP16 matches at 104.8 TFLOPS with a 1:1 ratio. The Ryzen Z2 GPU delivers 8.294 TFLOPS in both FP32 and FP16, also at 1:1.

Memory architecture separates the two further. The Ryzen Z2 GPU uses 16 GB of LPDDR5X on a 128-bit bus, with memory clocks at 937 MHz or 7.5 Gbps effective. That yields 119.9 GB/s of bandwidth. The RTX 5090 D uses 32 GB of GDDR7 on a 512-bit bus, with memory clocks at 1750 MHz or 28 Gbps effective. Its bandwidth reaches 1.79 TB/s, roughly fifteen times higher than the Ryzen part.

The power envelope reflects the performance gulf. The Ryzen Z2 GPU has a TDP of 28 W and requires no power connectors. The RTX 5090 D has a TDP of 575 W, uses a single 16-pin connector, and carries a suggested PSU rating of 950 W. The physical footprint differs as well: the RTX 5090 D is dual-slot, 304 mm long, 137 mm tall, and 48 mm wide, while the Ryzen Z2 GPU has no recorded dimensions.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5090 D uses a PCIe 5.0 x16 interface, while the Ryzen Z2 GPU has no recorded bus interface. Display outputs also differ: the Ryzen Z2 GPU has a single USB Type-C output, while the RTX 5090 D has one HDMI 2.1b and three DisplayPort 2.1b outputs.

Where Each One Wins

The RTX 5090 D wins decisively in every quantifiable performance category. Its FP32 throughput is roughly 12.6 times higher than the Ryzen Z2 GPU. Texture rate stands at 1,636.8 GTexel/s versus 129.6 GTexel/s. Pixel rate is 423.6 GPixel/s versus 86.40 GPixel/s. Memory bandwidth is 1.79 TB/s versus 119.9 GB/s. The RTX 5090 D also has double the VRAM (32 GB versus 16 GB), a wider bus (512-bit versus 128-bit), and far more shading units, TMUs, ROPs, ray tracing cores, and tensor cores.

The Ryzen Z2 GPU wins in efficiency-oriented categories that the data records. Its TDP is 28 W versus 575 W, a 20-fold difference. It requires no power connector and has no suggested PSU rating. The Ryzen part also has a smaller die (178 mm² versus 750 mm²) and higher transistor density (142.6M per mm² versus 122.9M per mm²). Its 4 nm process is one generation ahead of the 5 nm node used for the RTX 5090 D.

For use cases, the RTX 5090 D is the clear choice for high-resolution gaming, ray tracing workloads, and compute-heavy tasks. Its 32 GB VRAM and 1.79 TB/s bandwidth handle large textures and datasets. The 680 tensor cores support AI-accelerated features. The 170 ray tracing cores provide dedicated hardware for real-time ray tracing.

The Ryzen Z2 GPU suits low-power or embedded scenarios. Its 28 W TDP and lack of external power connectors make it suitable for compact systems. The single USB Type-C output limits display connectivity, but the part still supports DirectX 12 Ultimate and Vulkan 1.4. Its 16 GB LPDDR5X memory is generous for its power class, and the 119.9 GB/s bandwidth is modest but workable for lighter workloads.

The Verdict

The data presents an unambiguous performance hierarchy. The RTX 5090 D outperforms the Ryzen Z2 GPU in every measured compute, memory, and rendering metric. Its 104.8 TFLOPS FP32, 1.79 TB/s bandwidth, 32 GB VRAM, and 680 tensor cores place it in a completely different class. The 92nd percentile ranking confirms its position among the top GPUs in the database.

The Ryzen Z2 GPU offers only efficiency advantages. Its 28 W TDP, lack of external power connectors, and compact 178 mm² die make it suitable for low-power systems. Its 4 nm process node and higher transistor density are technical wins, but they do not translate into competitive performance. The absence of benchmark data means the database cannot quantify its real-world capabilities.

For a builder selecting a high-end desktop GPU, the RTX 5090 D is the clear choice based on specifications and recorded scores. Its nearest rivals in the database are all within 2.4% of its average score, which suggests it competes at the top tier of consumer and workstation parts. The Ryzen Z2 GPU, with its 50th percentile rank and zero recorded benchmarks, appears aimed at a fundamentally different market segment. The data supports choosing the RTX 5090 D for any performance-sensitive workload and the Ryzen Z2 GPU only where power draw and physical footprint take priority over raw output.
