AMD Ryzen Z2 Go GPU vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries between the AMD Ryzen Z2 Go GPU and the NVIDIA RTX PRO 5000 Blackwell. The AMD side carries no benchmark scores in the database, while the NVIDIA side has three recorded tests. This leaves comparison entirely dependent on the NVIDIA results and the architectural specifications of both parts.

The NVIDIA RTX PRO 5000 Blackwell delivers a 3DMark Steel Nomad DX12 score of 9,579.5. Its Geekbench OpenCL score reaches 254,116, and the Vulkan test records 282,631. The average benchmark score across these tests is 182,109. That average places the card in the 98th percentile of all GPUs in the database. The AMD Ryzen Z2 Go GPU has no benchmark scores, and its percentile sits at 50, indicating the midpoint of the database distribution, but this is not derived from any measured workload.

Comparing the NVIDIA card to its nearest rivals, the data shows it is 0.9% behind the NVIDIA A100 SXM4 80 GB, 1.4% behind the NVIDIA RTX 5000 Ada Generation, and 2.7% behind the NVIDIA A100 SXM4 40 GB. It is 2.3% ahead of the NVIDIA GeForce RTX 4090 D. These deltas are small, meaning the RTX PRO 5000 Blackwell sits in a tight performance cluster with those four cards around the 178,000 to 187,000 average score range.

The AMD part has no recorded wins, and the NVIDIA part has no recorded wins in the head-to-head table, since that table is empty. All comparative statements must therefore rely on the specification sheet rather than measured performance data.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip with RDNA 2.0 architecture, built on a 6 nm process at TSMC. It integrates 13,100 million transistors on a 208 mm² die, giving a transistor density of 63.0 million per square millimeter. The NVIDIA RTX PRO 5000 Blackwell uses the GB202 chip with Blackwell 2.0 architecture, also fabricated by TSMC but on a 5 nm process. Its die holds 92,200 million transistors across 750 mm², for a density of 122.9 million per square millimeter.

The process difference is one node step, but the transistor count difference is enormous. NVIDIA packs roughly seven times more transistors into a die about 3.6 times larger. The density advantage is nearly 2x, which indicates a much more compact logic design in the Blackwell part.

Clock behavior differs sharply. The AMD GPU has a base clock of 800 MHz and a boost clock of 2700 MHz. The NVIDIA GPU has a base clock of 1740 MHz and a boost clock of 2377 MHz. The AMD part boosts higher, but its base clock is far lower. Memory clocks also diverge: AMD uses 800 MHz with 6.4 Gbps effective, while NVIDIA runs 1750 MHz with 28 Gbps effective.

The AMD GPU is a console-class integrated-style part with a 28 W TDP and no power connectors. The NVIDIA card is a discrete workstation GPU with a 300 W TDP, a dual-slot cooler, a single 16-pin power connector, and a suggested 700 W power supply. The AMD card has no bus interface listed, while the NVIDIA card uses PCIe 5.0 x16. Display outputs differ as well: AMD offers one USB Type-C output, NVIDIA provides four DisplayPort 2.1b outputs.

API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The underlying hardware implementation, however, is completely different.

The Verdict

The data indicates two products aimed at completely different segments. The AMD Ryzen Z2 Go GPU is a low-power, compact part with 28 W TDP, no external power, and a single USB Type-C display output. It uses an older RDNA 2.0 architecture on 6 nm and has a modest 4.147 TFLOPS FP32 rating. Its 16 GB of LPDDR5 memory and 102.4 GB/s bandwidth are sufficient for light embedded or handheld-class workloads, but its 768 shading units and 32 ROPs constrain heavy graphics.

The NVIDIA RTX PRO 5000 Blackwell is a high-end workstation accelerator with 48 GB of GDDR7, 1.34 TB/s bandwidth, 66.94 TFLOPS FP32, and 440 tensor cores. Its benchmark results place it in the 98th percentile of all GPUs, with an average score of 182,109. Its nearest rivals are all within roughly 3% in either direction, so it performs on par with the A100 SXM4 variants and the RTX 5000 Ada Generation, while slightly ahead of the GeForce RTX 4090 D.

Who should pick which is clear from the numbers. The AMD part suits scenarios where power draw is capped at 28 W and the system cannot supply auxiliary power. The NVIDIA part suits compute-heavy or professional rendering workloads where 48 GB memory, high bandwidth, and tensor core support matter. The 300 W TDP and dual-slot cooler require a workstation chassis with a 700 W power supply recommendation.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins in power efficiency. Its 28 W TDP is less than one-tenth of the NVIDIA card's 300 W TDP. It requires no power connectors, which simplifies integration into compact systems. Its smaller die area of 208 mm² and lower transistor count also indicate a cheaper, more thermally manageable production. The single USB Type-C output suggests it is designed for portable or embedded form factors.

The NVIDIA RTX PRO 5000 Blackwell wins in every raw performance category. Its FP32 output of 66.94 TFLOPS is over 16 times the AMD figure. Its texture rate of 1,045.9 GTexel/s is roughly 8 times higher. Its pixel rate of 380.3 GPixel/s is about 4.4 times higher. Memory bandwidth is 13 times higher. The 48 GB frame buffer is three times larger, which directly affects large dataset loading and high-resolution rendering.

In compute workloads, the NVIDIA card's 440 tensor cores provide dedicated matrix acceleration, a feature entirely absent from the AMD part. The 110 RT cores versus 12 also show a major gap in ray tracing throughput. The NVIDIA card's PCIe 5.0 x16 interface and four DisplayPort 2.1b outputs support multi-monitor professional setups, while the AMD card has one USB Type-C output.

Benchmark data confirms the NVIDIA card's standing. Its 98th percentile rank and average score of 182,109 place it among the top workstation accelerators in the database. The AMD card has no measured scores, so its performance class cannot be confirmed from recorded data, but its specifications place it firmly in the low-power segment. The verdict follows the numbers: AMD for minimal power and simple integration, NVIDIA for maximum compute and memory capacity.
