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

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark runs between the AMD Ryzen Z2 Go GPU and the NVIDIA GeForce RTX 5090 D. The database shows zero wins for either part in paired testing, and no individual benchmark scores exist for the AMD Ryzen Z2 Go GPU. However, the NVIDIA GeForce RTX 5090 D has a substantial set of measured results across multiple test suites, which can be examined against its own nearest rivals to establish performance context.

The RTX 5090 D delivers a PassMark G3D score of 44,065 and a PassMark GPU Compute score of 28,396. In Geekbench, the card records 310,674 in OpenCL and 376,915 in Vulkan. The 3DMark Steel Nomad DX12 result stands at 14,326. These figures place the RTX 5090 D at the 92nd percentile among all GPUs in the database, with an average benchmark score of 77,712.

The nearest rivals for the RTX 5090 D are tight. The AMD Radeon RX 6650M XT averages 76,904, which is 1.1% lower than the RTX 5090 D's average. The AMD Radeon RX 6850M XT averages 78,940, putting it 1.6% ahead. The NVIDIA Tesla P100 PCIe 12 GB averages 79,396, or 2.1% higher, and the NVIDIA Tesla P100 PCIe 16 GB averages 79,605, or 2.4% higher. This narrow spread indicates the RTX 5090 D sits in a competitive cluster where small percentage differences separate adjacent parts.

The absence of benchmark data for the AMD Ryzen Z2 Go GPU means its average score is recorded as zero, and its percentile ranking is 50th. This is not a measured performance result but rather a placeholder in the database for a part that has not yet accumulated any test submissions. The RTX 5090 D, by contrast, has ten recorded benchmark entries spanning DX9 through DX12, OpenCL, Vulkan, and compute workloads.

Architecture Differences

The two GPUs come from fundamentally different design lineages. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip built on RDNA 2.0 architecture, fabricated on TSMC's 6 nm process. The NVIDIA GeForce RTX 5090 D uses the GB202 chip built on Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process. The process node difference, 6 nm versus 5 nm, contributes to distinct transistor density characteristics.

Transistor counts diverge sharply. The AMD part contains 13,100 million transistors on a 208 mm² die, yielding a density of 63.0 million transistors per square millimeter. The NVIDIA part contains 92,200 million transistors on a 750 mm² die, yielding a density of 122.9 million per square millimeter. The RTX 5090 D packs roughly seven times the transistor count onto a die about 3.6 times larger, with nearly double the packing density.

Memory architectures are entirely different. The AMD Ryzen Z2 Go GPU uses 16 GB of LPDDR5 on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The RTX 5090 D uses 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s. The NVIDIA part has twice the capacity, four times the bus width, and roughly 17.5 times the bandwidth. Memory clocks also differ: 800 MHz with 6.4 Gbps effective for the AMD part versus 1750 MHz with 28 Gbps effective for the NVIDIA part.

Compute resources show a massive gap. The AMD part has 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores. The NVIDIA part has 21,760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. The shading unit count alone is over 28 times higher on the RTX 5090 D. Pixel rate for the AMD part is 86.40 GPixel/s versus 423.6 GPixel/s for the NVIDIA part. Texture rate is 129.6 GTexel/s versus 1,636.8 GTexel/s. FP32 throughput is 4.147 TFLOPS versus 104.8 TFLOPS, and FP16 is 8.294 TFLOPS (2:1) versus 104.8 TFLOPS (1:1). The RTX 5090 D sustains full-rate FP16, while the AMD part halves its rate.

Clock behavior differs as well. The AMD part runs a base clock of 800 MHz and a boost of 2700 MHz. The NVIDIA part runs a base of 2017 MHz and a boost of 2407 MHz. The AMD part has a higher boost ceiling but a much lower base, while the NVIDIA part stays higher across the range. Power draw is 28 W for the AMD part versus 575 W for the NVIDIA part, a 20-fold difference that reflects the scale of compute resources.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins decisively on power efficiency and physical footprint. Its 28 W TDP requires no external power connectors, while the RTX 5090 D demands a single 16-pin connector and a suggested power supply of 950 W. The AMD part lists no slot width, no length, no height, and no width in the database, indicating a compact embedded or mobile form factor. The RTX 5090 D measures 304 mm in length, 137 mm in height, and 48 mm in width, occupying a dual-slot configuration. For constrained chassis designs, the AMD part is the only viable option between the two.

The RTX 5090 D wins on every measured performance dimension. Its pixel rate is 4.9 times higher, its texture rate is 12.6 times higher, and its FP32 throughput is 25.3 times higher. The memory bandwidth advantage is even more pronounced at roughly 17.5 times. The RTX 5090 D also carries tensor cores, which the AMD part lacks entirely, making the NVIDIA card the only one of the pair with dedicated AI acceleration hardware.

The RTX 5090 D supports PCIe 5.0 x16, while the AMD part has no recorded bus interface. Display outputs differ: the AMD part provides a single USB Type-C connector, while the NVIDIA card offers one HDMI 2.1b and three DisplayPort 2.1b outputs. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is equal.

The AMD part was released on 2024-12-31, while the RTX 5090 D followed on 2025-01-29. The NVIDIA card has a recorded predecessor, GeForce 40, and successor, GeForce 60, while the AMD part has neither. Production status is Active for both.

The Verdict

The database shows two GPUs with no overlapping performance measurements. The AMD Ryzen Z2 Go GPU has no benchmark scores, no nearest rivals, and an average score of zero. The NVIDIA GeForce RTX 5090 D has a full suite of ten benchmark results, an average score of 77,712, and a 92nd percentile ranking. Any direct performance comparison must therefore rely on the architectural specifications rather than paired test data.

The recorded specifications indicate the RTX 5090 D is designed for maximum compute throughput. It delivers 25.3 times the FP32 performance, 12.6 times the texture rate, and 4.9 times the pixel rate of the AMD part. Its memory bandwidth advantage of roughly 17.5 times, combined with tensor cores for AI workloads, positions it as a high-end discrete graphics solution. The 575 W TDP and 950 W suggested power supply confirm this role.

The AMD Ryzen Z2 Go GPU, with its 28 W TDP, no power connectors, and single USB Type-C output, is built for a fundamentally different use case. Its 16 GB of LPDDR5 memory and 6 nm process suggest an integrated or low-power embedded design where energy consumption and physical space are primary constraints. The 50th percentile placeholder and zero average score in the database indicate that no performance data has been collected for this part yet.

Buyers selecting between these two parts face a clear tradeoff. The RTX 5090 D is the only one with measured performance data, and that data shows a top-tier result. The AMD part offers extreme power efficiency and a compact footprint, but its actual performance remains unmeasured in the database. The RTX 5090 D carries a launch MSRP of 2,299 USD, while no MSRP is recorded for the AMD part. For workloads requiring maximum compute, the RTX 5090 D is the supported choice. For power-constrained or space-constrained designs, the AMD part is the only one that fits the recorded physical and electrical requirements.
