AMD Ryzen Z1 GPU vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Ryzen Z1 GPU or the NVIDIA B200 SXM6. Both entries show an average benchmark score of zero, and the head-to-head benchmark array is empty. Consequently, no direct performance comparison can be made from measured results. The percentile ranking for both GPUs is identical at 50 percent, placing them at the median of the database's tracked GPUs, but this is a categorical position rather than a performance-derived score.

What can be stated from the recorded data is the theoretical compute ceiling of each part. The AMD Ryzen Z1 GPU delivers 2.560 TFLOPS of FP32 compute and 5.120 TFLOPS of FP16 compute using a 2:1 ratio. The NVIDIA B200 SXM6 delivers 69.34 TFLOPS of FP32 and 69.34 TFLOPS of FP16 with a 1:1 ratio. That makes the B200 SXM6 approximately 27 times faster in FP32 throughput and roughly 13.5 times faster in FP16 throughput, based strictly on the specification fields.

Pixel throughput tells a similar story. The Ryzen Z1 GPU reaches 20.00 GPixel/s, while the B200 SXM6 reaches 43.92 GPixel/s, a lead of roughly 2.2 times. Texture rate separates the two far more dramatically: 40.00 GTexel/s for the AMD part versus 1,083.4 GTexel/s for the NVIDIA part, a margin of about 27 times.

Memory bandwidth is another area of massive divergence. The Ryzen Z1 GPU has 51.20 GB/s of bandwidth from a 64-bit LPDDR5 interface. The B200 SXM6 has 8.19 TB/s from an 8192-bit HBM3e interface. The NVIDIA part offers roughly 160 times the memory bandwidth.

Architecture Differences

The two GPUs come from different design philosophies. The AMD Ryzen Z1 GPU is built on the Phoenix chip using the RDNA 3.0 architecture, classified in the database as a Console GPU generation. It is fabricated on a 4 nm process at TSMC with 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million transistors per square millimeter.

The NVIDIA B200 SXM6 uses the GB100 chip with Blackwell architecture, classified as Server Blackwell (Bxx). It is fabricated on a 5 nm process at TSMC with 208,000 million transistors on a 1,628 mm² die, yielding a transistor density of 127.8 million transistors per square millimeter. The B200 SXM6 has over eight times the transistor count of the Ryzen Z1 GPU.

Compute resources differ in scale and composition. The Ryzen Z1 GPU has 256 shading units, 16 texture mapping units, 8 raster output units, and 4 ray tracing cores. It has no tensor cores listed. The B200 SXM6 has 18,944 shading units, 592 texture mapping units, 24 raster output units, no ray tracing cores listed, and 592 tensor cores.

The memory subsystems are built for different workloads. The Ryzen Z1 GPU uses 16 GB of LPDDR5 with a 64-bit bus. The B200 SXM6 uses 180 GB of HBM3e with an 8192-bit bus. The memory clock rates also differ: 800 MHz with 6.4 Gbps effective for the AMD part, versus 2000 MHz with 8 Gbps effective for the NVIDIA part.

Power and physical specifications are far apart. The Ryzen Z1 GPU has a TDP of 30 W and requires no power connectors. The B200 SXM6 has a TDP of 1000 W and a suggested PSU of 1400 W. The NVIDIA part is an SXM Module form factor using a PCIe 6.0 x16 bus interface. The AMD part has no listed bus interface.

API support differs in kind. The Ryzen Z1 GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented role rather than a client graphics role. Both parts have no display outputs.

Where Each One Wins

Without recorded benchmark scores, the wins must be assessed from specification data. The Ryzen Z1 GPU wins in power efficiency by a large margin. Its 30 W TDP against the B200 SXM6's 1000 W TDP means the AMD part consumes about 3 percent of the power of the NVIDIA part. For constrained environments, that is the decisive factor.

The Ryzen Z1 GPU also wins on transistor density. At 142.6 million transistors per square millimeter on a 4 nm process, it exceeds the B200 SXM6's 127.8 million transistors per square millimeter on a 5 nm process. The AMD part also has a smaller physical footprint with its 280 mm length, 111 mm height, and 21 mm width; the NVIDIA part has no dimensions recorded.

The Ryzen Z1 GPU supports client graphics APIs, while the B200 SXM6 does not. DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 are all present on the AMD part, and all are marked N/A on the NVIDIA part. Any workload requiring those APIs must use the AMD GPU.

The B200 SXM6 wins on raw compute, memory capacity, memory bandwidth, pixel throughput, and texture throughput. Its 69.34 TFLOPS FP32 figure is about 27 times the Ryzen Z1 GPU's 2.560 TFLOPS. Its 180 GB memory capacity is over 11 times the 16 GB of the AMD part. Its 8.19 TB/s bandwidth is roughly 160 times higher. Its 43.92 GPixel/s pixel rate is about 2.2 times higher, and its 1,083.4 GTexel/s texture rate is about 27 times higher.

The B200 SXM6 also has tensor cores, 592 of them, while the Ryzen Z1 GPU has none listed. The NVIDIA part also supports FP16 at a 1:1 ratio, meaning no throughput penalty for half-precision work, whereas the AMD part's 2:1 ratio halves its FP16 throughput relative to FP32.

The Verdict

The data separates these two GPUs into distinct roles. The AMD Ryzen Z1 GPU is a low-power client graphics part with a 30 W TDP, DirectX 12 Ultimate support, and a compact 280 mm length. Its 4 nm process gives it the higher transistor density of the two at 142.6 million transistors per square millimeter. It is suited for workloads that need modern graphics APIs and minimal power draw.

The NVIDIA B200 SXM6 is a high-power server accelerator with a 1000 W TDP, 180 GB of HBM3e memory, 592 tensor cores, and a PCIe 6.0 x16 interface. Its compute figures dominate: 69.34 TFLOPS FP32, 69.34 TFLOPS FP16 at 1:1 ratio, 8.19 TB/s bandwidth, and 1,083.4 GTexel/s texture rate. It has no client graphics API support and no display outputs.

Selection depends on the workload. For client graphics, the Ryzen Z1 GPU is the only option with DirectX and Vulkan support. For server-scale compute, memory bandwidth, or tensor operations, the B200 SXM6 is the clear choice from the recorded data. The 27 times FP32 advantage and 160 times bandwidth advantage are decisive for compute-heavy tasks. The Ryzen Z1 GPU's 30 W power envelope is decisive for power-constrained deployments. Both GPUs are active in production and have no recorded benchmark scores, so the verdict rests entirely on specification differences.
