AMD Ryzen Z2 A GPU vs NVIDIA RTX PRO 4000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded benchmark data places these two processors in very different performance tiers. The AMD Ryzen Z2 A GPU has no benchmark entries in the database, while the NVIDIA RTX PRO 4000 Blackwell has nine recorded results across multiple test suites. The NVIDIA part carries a percentile ranking of 72 among all GPUs in the database, while the AMD part sits at the 50th percentile. The average benchmark score for the NVIDIA RTX PRO 4000 Blackwell is 27,135, and its nearest rivals in the database include the AMD Radeon RX 6700 XT with an average score of 27,425 (1.1% higher), the NVIDIA GeForce RTX 4070 Mobile with 27,435 (1.1% higher), the NVIDIA GeForce RTX 3090 with 27,565 (1.6% higher), and the NVIDIA RTX A4000 with 26,683 (1.7% lower). This places the RTX PRO 4000 Blackwell within a tight cluster of established desktop and mobile GPUs, all within roughly two percentage points of its average score.

Within its own benchmark suite, the RTX PRO 4000 Blackwell shows a wide spread of results depending on the workload. In the Passmark G3D test, it records 28,427 points, while the Passmark G2D test yields 1,265 points. The Geekbench Vulkan result is 194,168 points, and the 3DMark Steel Nomad DX12 test produces 4,648 points. Compute-oriented tests produce 14,805 points in Passmark GPU Compute. The DirectX 9, 10, 11, and 12 Passmark tests produce 354, 173, 276, and 97 points respectively.

Because the AMD Ryzen Z2 A GPU has no recorded benchmark scores, the head-to-head comparison is one-sided. The data confirms that the NVIDIA part outperforms the AMD part across every measurable category, but the lack of AMD scores means no specific delta percentage can be established from direct comparison. The database treats the AMD part as a zero-score entry, which places it far below the NVIDIA part's 27,135 average.

The nearest rival data for the NVIDIA part provides useful context. Its average score trails the AMD Radeon RX 6700 XT by only 1.1%, trails the NVIDIA GeForce RTX 4070 Mobile by 1.1%, and trails the NVIDIA GeForce RTX 3090 by 1.6%. It leads the NVIDIA RTX A4000 by 1.7%. This tight grouping suggests that the RTX PRO 4000 Blackwell delivers performance consistent with upper-midrange GPUs in the database, despite its workstation-oriented positioning.

Architecture Differences

The two processors come from different manufacturers, use different process nodes, and implement different architectures. The AMD Ryzen Z2 A GPU uses the Van Gogh chip, built on RDNA 2.0 architecture, manufactured by TSMC on a 7 nm process. The NVIDIA RTX PRO 4000 Blackwell uses the GB203 chip, built on Blackwell 2.0 architecture, also manufactured by TSMC but on a 5 nm process. The process node difference is significant, as the 5 nm node allows for substantially higher transistor density.

The transistor counts differ by an order of magnitude. The AMD part contains 2,400 million transistors on a die size of 163 mm², yielding a transistor density of 14.7 million transistors per square millimeter. The NVIDIA part contains 45,600 million transistors on a die size of 378 mm², yielding a transistor density of 120.6 million transistors per square millimeter. The NVIDIA die is larger in absolute terms, but the density advantage is even more pronounced, with roughly eight times more transistors per square millimeter.

Memory subsystems are entirely different. The AMD Ryzen Z2 A GPU uses 16 GB of LPDDR5 memory on a 128-bit bus, with a memory clock of 800 MHz and 6.4 Gbps effective data rate, producing 102.4 GB/s of bandwidth. The NVIDIA RTX PRO 4000 Blackwell uses 24 GB of GDDR7 memory on a 192-bit bus, with a memory clock of 1750 MHz and 28 Gbps effective data rate, producing 672.0 GB/s of bandwidth. The NVIDIA part has 50% more memory capacity and roughly 6.5 times the memory bandwidth.

Core configurations are vastly different. The AMD part has 512 shading units, 32 texture mapping units, 16 render output units, and 8 ray tracing cores. The NVIDIA part has 8,960 shading units, 280 texture mapping units, 96 render output units, 70 ray tracing cores, and 280 tensor cores. The AMD part has no tensor cores listed. The NVIDIA part has 17.5 times the shading units, 8.75 times the TMUs, and 6 times the ROPs relative to the AMD part.

Clock speeds also differ. The AMD part has a base clock of 1000 MHz and a boost clock of 1600 MHz. The NVIDIA part has a base clock of 1230 MHz and a boost clock of 2055 MHz. The NVIDIA boost clock is 455 MHz higher. The NVIDIA part also has a much higher memory clock at 1750 MHz versus 800 MHz.

Pixel and texture rates reflect the core and clock differences. The AMD part delivers 25.60 GPixel/s and 51.20 GTexel/s. The NVIDIA part delivers 197.3 GPixel/s and 575.4 GTexel/s. Floating point performance shows the largest gap: the AMD part delivers 1.638 TFLOPS FP32 and 3.277 TFLOPS FP16 at a 2:1 ratio, while the NVIDIA part delivers 36.83 TFLOPS FP32 and 36.83 TFLOPS FP16 at a 1:1 ratio. The NVIDIA FP32 throughput is roughly 22.5 times higher.

Power consumption differs dramatically. The AMD part has a TDP of 15 W, while the NVIDIA part has a TDP of 140 W. The NVIDIA part requires a 16-pin power connector and a suggested power supply of 300 W, while the AMD part lists no power connectors and no suggested PSU. The AMD part is a single USB Type-C display output device, while the NVIDIA part provides four DisplayPort 2.1b outputs and uses a PCIe 5.0 x16 bus interface. The AMD part lists no bus interface in the database.

Where Each One Wins

The AMD Ryzen Z2 A GPU has no benchmark wins in the database. Its 15 W TDP is the only category where the AMD part holds an advantage over the NVIDIA part, which draws 140 W. For scenarios where power draw is the primary constraint, the AMD part consumes roughly one tenth of the power of the NVIDIA part. The AMD part also uses LPDDR5 memory, which is a lower-power memory type compared to GDDR7.

The NVIDIA RTX PRO 4000 Blackwell wins every measured benchmark category. Its 24 GB of GDDR7 memory with 672.0 GB/s bandwidth makes it suitable for memory-intensive workloads. The presence of 280 tensor cores provides dedicated hardware for AI and compute tasks, a feature entirely absent from the AMD part. The 70 ray tracing cores enable hardware-accelerated ray tracing, compared to 8 ray tracing cores on the AMD part.

The NVIDIA part's single-slot form factor, 241 mm length, 111 mm height, and 20 mm width, combined with four DisplayPort 2.1b outputs, positions it for multi-display workstation use. The AMD part's single USB Type-C output limits it to a single display connection. The NVIDIA part's PCIe 5.0 x16 interface provides a modern host connection, while the AMD part lists no bus interface.

The benchmark data shows the NVIDIA part's Passmark G3D score of 28,427 and its Geekbench Vulkan score of 194,168, both of which are strong indicators of general graphics performance. The 3DMark Steel Nomad DX12 score of 4,648 reflects modern DirectX 12 workload capability. The Passmark GPU Compute score of 14,805 indicates compute throughput that the AMD part cannot match based on its FP32 and FP16 specifications.

The AMD part does have a release date earlier than the NVIDIA part. The AMD Ryzen Z2 A GPU was released on 2024-12-31, while the NVIDIA RTX PRO 4000 Blackwell was released on 2025-03-17. Both parts are listed as Active in production status. The NVIDIA part has a predecessor listed as Workstation Ada, while the AMD part has no predecessor listed.
