AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 5090 D V2 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Ryzen Z2 GPU and the NVIDIA GeForce RTX 5090 D V2. The head-to-head benchmark array is empty, and the win counters for both products stand at zero. This means the comparison must rely entirely on the available specification data, architectural details, and the single benchmark score recorded for the NVIDIA part.

The only numerical benchmark in the database is the NVIDIA GeForce RTX 5090 D V2's result in 3DMark Steel Nomad DX12, where it scored 16,504 points. This score places the RTX 5090 D V2 at the 59th percentile among all GPUs in the database. Its nearest rivals in that benchmark are tightly clustered: the NVIDIA T400 scores 16,508 points (0% delta), the AMD Radeon PRO W7500 scores 16,415 points (0.5% slower), the NVIDIA RTX PRO 6000 Blackwell scores 16,408 points (0.6% slower), and the AMD Radeon RX 5700 XT scores 16,361 points (0.9% slower). The RTX 5090 D V2 is therefore effectively tied with these four cards in this specific test, despite the massive hardware differences.

The AMD Ryzen Z2 GPU has no recorded benchmark scores, an average benchmark score of zero, and sits at the 50th percentile in the database's overall distribution. Its nearest rivals list is empty. Consequently, the data cannot show a single head-to-head winner in any benchmark category. The comparison below is therefore a specification-level analysis, not a benchmark-driven one.

Where Each One Wins

Based strictly on the recorded data, the NVIDIA GeForce RTX 5090 D V2 wins on every measurable performance metric. Its FP32 compute reaches 104.8 TFLOPS, compared to the AMD Ryzen Z2 GPU's 8.294 TFLOPS. That is a 12.6x advantage in raw shader throughput. The pixel rate favors NVIDIA at 423.6 GPixel/s versus 86.40 GPixel/s, a 4.9x difference. Texture rate goes to NVIDIA as well: 1,636.8 GTexel/s versus 129.6 GTexel/s, a 12.6x margin. The memory subsystem also heavily favors NVIDIA: 24 GB of GDDR7 on a 384-bit bus delivers 1.34 TB/s of bandwidth, while the AMD part offers 16 GB of LPDDR5X on a 128-bit bus at 119.9 GB/s. That is an 11.2x bandwidth advantage.

The RTX 5090 D V2 also carries more hardware resources in every compute category. It has 21,760 shading units, 680 texture mapping units, 176 raster operations units, 170 ray tracing cores, and 680 tensor cores. The AMD Ryzen Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores, with no tensor core count listed. The NVIDIA part's transistor count is 92,200 million versus 25,390 million, and its die size is 750 mm² versus 178 mm². The RTX 5090 D V2 also supports PCIe 5.0 x16, while the AMD part has no bus interface listed.

The AMD Ryzen Z2 GPU does win in power efficiency based on the data. Its TDP is 28 W, and it requires no power connectors. The RTX 5090 D V2 has a 575 W TDP and requires a 1x 16-pin power connector, with a suggested PSU of 950 W. That means the AMD part draws 547 W less at the TDP level. The AMD chip also uses a smaller process node at 4 nm versus 5 nm for the NVIDIA part, and it has a higher transistor density: 142.6M per mm² versus 122.9M per mm². The AMD part is also physically smaller, which may matter in constrained installations, though its dimensions are not listed in the database.

The RTX 5090 D V2 is the only one with a recorded benchmark score, so it wins the only measurable performance test in the database. The AMD part has no wins recorded in any category because no benchmark data exists for it.

The Verdict

The data indicates that the NVIDIA GeForce RTX 5090 D V2 is the significantly more capable graphics processor in every performance-oriented specification. Its compute throughput, memory bandwidth, pixel and texture rates, and ray tracing resources are all orders of magnitude higher than the AMD Ryzen Z2 GPU. The single benchmark score confirms that it can produce a 16,504-point result in 3DMark Steel Nomad DX12, placing it in the 59th percentile of all GPUs. The AMD part has no benchmark data, so it cannot be placed relative to any rival in the database.

The AMD Ryzen Z2 GPU, however, is the clear choice for scenarios where power consumption is the primary constraint. Its 28 W TDP and connector-free design make it suitable for low-power or embedded contexts, and its 4 nm process node with higher transistor density suggests a more integrated, efficient design. The RTX 5090 D V2 requires a 950 W suggested PSU and a 16-pin connector, which places it in a completely different power class.

A user who needs maximum graphics performance, ray tracing capability, and memory bandwidth should select the RTX 5090 D V2. A user who needs a low-power, compact GPU with no external power requirement should select the AMD Ryzen Z2 GPU, provided the workload does not demand the performance levels that the NVIDIA part delivers. The data does not support any middle ground, as the two products occupy opposite ends of the performance and power spectrum.

Architecture Differences

The AMD Ryzen Z2 GPU is built on the RDNA 3.0 architecture and uses the Hawk Point chip. It is classified in the database as a Console GPU generation from AMD. The NVIDIA GeForce RTX 5090 D V2 uses the Blackwell 2.0 architecture with the GB202 chip and belongs to the GeForce 50-series. These are fundamentally different design philosophies. The RDNA 3.0 architecture targets low-power integrated graphics, as evidenced by the 28 W TDP and the absence of any power connector. The Blackwell 2.0 architecture targets high-end desktop graphics, with a 575 W TDP and a 16-pin power connector.

The AMD part has 768 shading units, 48 TMUs, and 32 ROPs. The NVIDIA part has 21,760 shading units, 680 TMUs, and 176 ROPs. Ray tracing hardware also differs significantly: the AMD part has 12 RT cores, while the NVIDIA part has 170 RT cores. The NVIDIA part additionally includes 680 tensor cores, which the AMD part does not list at all. This indicates that the RTX 5090 D V2 is designed for AI-accelerated workloads, while the AMD part does not expose such hardware in the database.

Memory architecture also diverges. The AMD part uses LPDDR5X, which is a low-power memory type commonly used in integrated or mobile contexts. The NVIDIA part uses GDDR7, a high-bandwidth discrete memory type. The bus widths reflect this: 128-bit for AMD versus 384-bit for NVIDIA. The transistor counts and die sizes reinforce the distinction. The AMD chip integrates 25,390 million transistors on a 178 mm² die, while the NVIDIA chip integrates 92,200 million transistors on a 750 mm² die. The AMD part's higher transistor density (142.6M per mm²) suggests a more compact, efficient layout, whereas the NVIDIA part uses a larger die to accommodate more compute resources.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part has a PCIe 5.0 x16 interface, while the AMD part has no bus interface listed. Display outputs differ as well: the AMD part has a single USB Type-C output, while the NVIDIA part offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. The NVIDIA part is dual-slot and measures 304 mm by 137 mm by 48 mm, while the AMD part has no dimensions recorded.
