AMD Ryzen Z2 Go GPU vs NVIDIA GeForce RTX 5090 Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for the NVIDIA GeForce RTX 5090, but no comparable scores for the AMD Ryzen Z2 Go GPU. The Ryzen Z2 Go has no benchmark entries, no average score, and no nearest rivals listed. The RTX 5090, by contrast, carries a full suite of ten recorded tests across DirectX, OpenCL, Vulkan, and compute workloads.

The RTX 5090 posts a 3DMark Steel Nomad DX12 score of 18,355. In Geekbench, it records 334,370 for OpenCL and 376,728 for Vulkan. Passmark results are more varied: G3D scores 39,650, GPU compute scores 26,756, and G2D scores 1,413. The legacy DirectX tests show 395 for DirectX 9, 341 for DirectX 11, 226 for DirectX 10, and 185 for DirectX 12. Its average benchmark score across all tests is 79,842.

The Ryzen Z2 Go has no such data. There are no wins for the AMD part in head-to-head comparisons, and likewise no wins for the NVIDIA part, because no shared test results exist in the database. The percentile ranking tells the story: the RTX 5090 sits at the 92nd percentile of all GPUs, while the Ryzen Z2 Go sits at the 50th percentile. That percentile gap, based on the database's broader tracking, places the two parts far apart in overall standing.

The nearest rivals to the RTX 5090 provide context for its average score. The Tesla P100 PCIe 16 GB averages 79,605, which is 0.3% lower. The Tesla P100 PCIe 12 GB averages 79,396, 0.6% lower. The Radeon RX 6850M XT averages 78,940, 1.1% lower. The Radeon Pro Vega 64X averages 80,959, which is 1.4% higher. These deltas are small, indicating a tight cluster of comparable performers around the RTX 5090's average, despite the RTX 5090's commanding raw specifications.

The Ryzen Z2 Go has no nearest rivals, no average score, and no percentile context beyond the 50th percentile figure. Direct numerical comparison between these two products is therefore impossible from the database alone. The only honest statement the data supports is that the RTX 5090 has extensive recorded performance, while the Ryzen Z2 Go has none.

The Verdict

The data supports only one clear conclusion: the NVIDIA GeForce RTX 5090 is a fully measured product with a 92nd percentile ranking and an average benchmark score of 79,842. The AMD Ryzen Z2 Go has zero recorded benchmarks and an average score of zero. Anyone relying on the database for performance validation will find substantial evidence for the RTX 5090 and no evidence at all for the Ryzen Z2 Go.

The RTX 5090's nearest rivals, all within roughly 1.4% of its average score, show that its measured performance is consistent with a well-established high-end tier. The AMD part cannot be placed in any performance tier because no test results exist.

For users who require database-verified performance, the RTX 5090 is the only option with supporting measurements. The Ryzen Z2 Go may have architectural merits, but the recorded data provides no basis for evaluating them. The verdict is not about which chip is faster; it is about which chip has verifiable data. That chip is the RTX 5090.

Architecture Differences

The two GPUs diverge at nearly every architectural level. The AMD Ryzen Z2 Go uses the Rembrandt+ chip with RDNA 2.0 architecture, built on TSMC's 6 nm process. It contains 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0 million per mm². The NVIDIA GeForce RTX 5090 uses the GB202 chip with Blackwell 2.0 architecture, built on TSMC's 5 nm process. It contains 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9 million per mm². The RTX 5090 has more than seven times the transistor count and more than 3.5 times the die area.

Clock behavior also differs sharply. The Ryzen Z2 Go has a base clock of 800 MHz and a boost clock of 2,700 MHz. The RTX 5090 has a base clock of 2,017 MHz and a boost clock of 2,407 MHz. The AMD part boosts higher than the NVIDIA part, but the NVIDIA part starts from a much higher base.

Memory configurations are in different classes. The Ryzen Z2 Go uses 16 GB of LPDDR5 on a 128-bit bus, with 800 MHz memory clock and 6.4 Gbps effective speed. Bandwidth reaches 102.4 GB/s. The RTX 5090 uses 32 GB of GDDR7 on a 512-bit bus, with 1,750 MHz memory clock and 28 Gbps effective speed. Bandwidth reaches 1.79 TB/s, which is roughly 17.5 times higher than the AMD part.

Compute resources show an even wider gulf. The Ryzen Z2 Go has 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores. The RTX 5090 has 21,760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. The NVIDIA part has roughly 28 times as many shading units, 14 times as many TMUs, 5.5 times as many ROPs, and 14 times as many RT cores.

Pixel and texture rates follow the same pattern. The Ryzen Z2 Go delivers 86.40 GPixel/s and 129.6 GTexel/s. The RTX 5090 delivers 423.6 GPixel/s and 1,636.8 GTexel/s. Floating-point throughput is similarly lopsided: the Ryzen Z2 Go reaches 4.147 TFLOPS FP32 and 8.294 TFLOPS FP16 (2:1 ratio), while the RTX 5090 reaches 104.8 TFLOPS for both FP32 and FP16 (1:1 ratio). The RTX 5090 delivers over 25 times the FP32 throughput.

Power and physical specifications are equally distinct. The Ryzen Z2 Go has a 28 W TDP, no power connectors, and a single USB Type-C display output. The RTX 5090 has a 575 W TDP, a single 16-pin connector, a suggested PSU of 950 W, a dual-slot cooler, and dimensions of 304 mm by 137 mm by 40 mm. It offers 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs. The RTX 5090 uses a PCIe 5.0 x16 interface, while the Ryzen Z2 Go lists no bus interface.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Ryzen Z2 Go is classified as a console GPU from the RDNA 2.0 generation, while the RTX 5090 belongs to the GeForce 50-series with Blackwell 2.0. The RTX 5090 lists a predecessor (GeForce 40) and a successor (GeForce 60); the Ryzen Z2 Go lists neither.

Where Each One Wins

The Ryzen Z2 Go wins on power efficiency and compact integration. Its 28 W TDP requires no power connectors, and its single USB Type-C output suggests a low-footprint deployment. It boosts to 2,700 MHz, which is higher than the RTX 5090's 2,407 MHz boost. It also uses a 6 nm process versus the RTX 5090's 5 nm, though the RTX 5090 achieves a higher transistor density of 122.9M per mm² compared to 63.0M per mm².

The RTX 5090 wins on every measured performance metric in the database. Its average benchmark score of 79,842 places it at the 92nd percentile, while the Ryzen Z2 Go sits at the 50th percentile with no recorded scores. The RTX 5090 has 32 GB of GDDR7 memory with 1.79 TB/s bandwidth, compared to 16 GB of LPDDR5 with 102.4 GB/s. It delivers 104.8 TFLOPS FP32 versus 4.147 TFLOPS. It has 21,760 shading units versus 768. It has 170 RT cores versus 12. It has 680 tensor cores, a feature the Ryzen Z2 Go lacks entirely.

For use cases, the data points to a clear split. The Ryzen Z2 Go suits scenarios where power draw and physical simplicity matter: no external power connectors, a 28 W envelope, and a single display output. Its 16 GB LPDDR5 and 128-bit bus are modest but self-contained. The RTX 5090 suits scenarios demanding maximum throughput: its 423.6 GPixel/s pixel rate, 1,636.8 GTexel/s texture rate, and 1.79 TB/s bandwidth support high-resolution rendering and compute-heavy workloads. Its 575 W TDP and 950 W suggested PSU indicate a desktop-class installation with robust power delivery.

The database records no head-to-head benchmark wins for either product, because no shared tests exist. The RTX 5090's recorded scores stand alone. The Ryzen Z2 Go's absence of data means it cannot claim a single verified performance win in this comparison. The RTX 5090 also carries a launch MSRP of 1,999 USD, while the Ryzen Z2 Go has no listed launch MSRP.

Selecting between the two depends entirely on whether the requirement is minimal power draw or maximum verified performance. The data confirms the RTX 5090 as the measured performer. The Ryzen Z2 Go remains an unverified entry in the database, defined only by its architectural specifications and power characteristics.
