AMD Ryzen Z2 GPU vs NVIDIA GB10 Comparison

Head-to-Head Benchmarks

The direct comparison between the AMD Ryzen Z2 GPU and NVIDIA GB10 is stark, with the GB10 dominating in every measurable category. The GB10's recorded benchmark results show an average score of 117,393 across Geekbench OpenCL and Vulkan tests, placing it in the 95th percentile of all GPUs in the database. The Ryzen Z2 GPU has no recorded benchmark scores and sits at the 50th percentile, indicating a mid-pack position relative to all tracked GPUs.

Looking at raw computational throughput, the GB10 delivers 29.71 TFLOPS of FP32 performance, while the Ryzen Z2 GPU produces 8.294 TFLOPS. This represents a 3.6x advantage for the GB10 in single-precision floating-point work. The texture fill rate tells a similar story: the GB10 achieves 928.5 GTexel/s versus 129.6 GTexel/s for the AMD part, a 7.2x margin. Pixel throughput favors the GB10 as well, with 116.1 GPixel/s compared to 86.40 GPixel/s, a 1.3x lead.

In memory performance, the GB10's 273.2 GB/s bandwidth is 2.3x higher than the Ryzen Z2 GPU's 119.9 GB/s. The GB10 also carries 128 GB of LPDDR5X memory versus 16 GB on the AMD chip, an 8x capacity advantage. The GB10's closest rivals in the database include the NVIDIA RTX 4000 SFF Ada Generation, which scores 0.3% higher, and the AMD Radeon PRO W7700, which trails by 1.3%. The GB10 outperforms the NVIDIA Tesla V100 SXM2 16 GB by 2.6% and the NVIDIA RTX A5500 Mobile by 3%.

Architecture Differences

The two chips come from fundamentally different design philosophies. The AMD Ryzen Z2 GPU uses the Hawk Point chip built on RDNA 3.0 architecture, manufactured on a 4 nm process at TSMC. It packs 25,390 million transistors into a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. This is a console-oriented GPU design with a 28 W TDP, meaning it targets power-constrained environments.

The NVIDIA GB10 uses the GB20B chip with Blackwell 2.0 architecture, also fabricated by TSMC but on a 5 nm node. Its die measures 382 mm², more than double the AMD chip's area, though the transistor count is listed as unknown in the database. The GB10 is classified as a Server Blackwell part with a 140 W TDP and a suggested PSU of 300 W. It occupies an IGP slot width and measures 150 mm by 51 mm by 150 mm.

The compute resources differ dramatically. The GB10 fields 6,144 shading units, 384 texture mapping units, 48 ROPs, 48 RT cores, and 384 tensor cores. The Ryzen Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores, with no tensor cores listed. The GB10's tensor core count gives it a dedicated path for AI and machine learning workloads that the AMD part simply lacks.

Clock behavior also distinguishes the two. The GB10 has a base clock of 1665 MHz and a boost clock of 2418 MHz, while the Ryzen Z2 GPU starts at 800 MHz and boosts to 2700 MHz. Despite the AMD chip's higher peak clock, the GB10's massive shader count more than compensates. Memory clocks show 1067 MHz (8.5 Gbps effective) on the GB10 versus 937 MHz (7.5 Gbps effective) on the AMD part.

API support diverges sharply. The Ryzen Z2 GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it suitable for gaming and consumer graphics workloads. The GB10 lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for traditional graphics APIs. Display outputs also differ: the AMD chip has 1x USB Type-C, while the GB10 has 1x HDMI.

Where Each One Wins

The NVIDIA GB10 wins decisively in compute-heavy workloads. Its 29.71 TFLOPS FP32 and FP16 performance, combined with 384 tensor cores, positions it for scientific computing, server-side inference, and large-scale data processing. The 128 GB memory capacity allows it to handle datasets that would exhaust the Ryzen Z2 GPU's 16 GB frame buffer entirely. The 273.2 GB/s memory bandwidth supports high-throughput data movement, and the PCIe 5.0 x16 bus interface provides a fast host connection.

The AMD Ryzen Z2 GPU wins on efficiency and integration. Its 28 W TDP is one-fifth of the GB10's 140 W draw, making it suitable for compact, battery-powered or passively cooled systems. The 4 nm process node gives it a density advantage at 142.6M transistors per mm², and its smaller die size of 178 mm² reduces manufacturing complexity. The RDNA 3.0 architecture with DirectX 12 Ultimate support and Vulkan 1.4 means it can run consumer games and graphics applications natively, something the GB10 cannot do given its N/A API entries.

The Ryzen Z2 GPU also wins on physical footprint and output flexibility. It requires no power connectors, uses a single USB Type-C for display, and has no listed dimensions, suggesting an extremely compact integrated design. The GB10, while also connector-free, requires a 300 W suggested PSU and comes in a larger 150 mm package.

The Verdict

The data points to two completely different products for completely different roles. The NVIDIA GB10 is a server-class compute accelerator with 128 GB of memory, 384 tensor cores, and 29.71 TFLOPS of FP32 throughput. Its 95th percentile benchmark standing and average score of 117,393 confirm it as a high-end part that competes with workstation GPUs like the RTX 4000 SFF Ada Generation and Radeon PRO W7700. It carries a launch MSRP of 3,999 USD and targets workloads where memory capacity and compute density matter more than power efficiency or graphics API compatibility.

The AMD Ryzen Z2 GPU is a console-oriented integrated part with 16 GB of memory, 12 RT cores, and 8.294 TFLOPS. Its 28 W TDP and DirectX 12 Ultimate support make it suitable for gaming handhelds or compact consoles where power draw and API compatibility are critical. The lack of recorded benchmarks means its real-world performance is unverified in the database, but its 50th percentile ranking suggests it sits at the middle of the field.

Users needing server-grade compute, large memory pools, or AI acceleration should choose the GB10. Users needing a low-power graphics solution with gaming API support should choose the Ryzen Z2 GPU. The two parts do not overlap in purpose, and the benchmark data reflects that separation.
