AMD Ryzen AI Z2 Extreme GPU vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the AMD Ryzen AI Z2 Extreme GPU against the NVIDIA Rubin GPU. With zero wins recorded for either part and an empty benchmark comparison set, the two products cannot be ranked against each other using measured performance data. Both occupy the 50th percentile versus all GPUs in the database, and both carry an average benchmark score of 0, which reflects the absence of test results rather than any actual performance parity.

The AMD Ryzen AI Z2 Extreme GPU delivers 5.530 TFLOPS of FP32 compute and 5.530 TFLOPS of FP16 compute with a 1:1 ratio. The NVIDIA Rubin GPU delivers 130.0 TFLOPS of FP32 compute and 260.0 TFLOPS of FP16 compute with a 2:1 ratio. In raw arithmetic throughput, the Rubin part is roughly 23.5 times higher in FP32 and roughly 47 times higher in FP16. These figures come directly from the recorded specification data, not from any benchmark run.

Pixel throughput differs sharply. The AMD part reaches 129.6 GPixel/s, while the NVIDIA part reaches only 54.41 GPixel/s. Texture throughput reverses the situation: the AMD part reaches 172.8 GTexel/s, while the NVIDIA part reaches 2,031.2 GTexel/s. The NVIDIA part is approximately 11.8 times higher in texture rate, while the AMD part is approximately 2.4 times higher in pixel rate.

Memory bandwidth is another major separator. The AMD part uses a 256-bit bus with LPDDR5X memory at 256.0 GB/s. The NVIDIA part uses a 16384-bit bus with HBM4 memory at 22.1 TB/s, which is approximately 86 times higher. Memory capacity also differs drastically: 16 GB versus 288 GB.

Clock speeds show the AMD part operating at a base of 800 MHz and a boost of 2700 MHz, while the NVIDIA part runs at a base of 700 MHz and a boost of 2267 MHz. The AMD part holds a higher boost clock by about 19%. Memory clocks differ as well: the AMD part runs at 1000 MHz with 8 Gbps effective, while the NVIDIA part runs at 2695 MHz with 10.8 Gbps effective.

Because no benchmark scores exist, any head-to-head comparison must rely entirely on the specification sheet. The data indicates two products built for entirely different workloads, with the NVIDIA part dominating in compute, memory, and texture throughput, while the AMD part leads in pixel rate and boost clock.

Where Each One Wins

The AMD Ryzen AI Z2 Extreme GPU wins in scenarios that depend on pixel fill rate. Its 129.6 GPixel/s output, combined with 48 ROPs, suits rasterization workloads where triangle setup and pixel shading dominate. The higher boost clock of 2700 MHz also supports latency-sensitive tasks that scale with frequency rather than raw shader count. Its 16 GB of LPDDR5X memory on a 256-bit bus provides 256.0 GB/s, a modest but functional amount for integrated-class graphics. The part lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support, indicating a full modern graphics API feature set. Its 28 W TDP and lack of power connectors place it in low-power, mobile or compact systems where thermal and electrical budgets are tight.

The NVIDIA Rubin GPU wins in scenarios that demand massive parallel compute, large memory capacities, or extreme bandwidth. Its 28672 shading units, 896 tensor cores, and 896 TMUs provide a compute foundation that far exceeds the AMD part. The 288 GB of HBM4 memory with 22.1 TB/s bandwidth is suited for large model inference, scientific simulation, or data-intensive server workloads. The 260.0 TFLOPS FP16 output with a 2:1 ratio indicates strong mixed-precision performance, which is typical for AI training and inference tasks. The 2,031.2 GTexel/s texture rate supports heavy texture sampling workloads. The PCIe 6.0 x16 interface and 2300 W TDP with a suggested 2700 W PSU indicate a server-class installation, using an SXM module form factor with no display outputs.

The AMD part has no tensor cores listed, while the NVIDIA part has 896. The AMD part has 16 RT cores, while the NVIDIA part lists no RT core count. The AMD part supports display output via 1x USB Type-C, while the NVIDIA part has no outputs. These differences define the use-case split: the AMD part targets graphics rendering and display, while the NVIDIA part targets compute and data processing without any display capability.

Architecture Differences

The AMD Ryzen AI Z2 Extreme GPU uses the Strix Point chip built on RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. The die contains 34,000 million transistors on a 233 mm² area, yielding a transistor density of 145.9M per mm². The NVIDIA Rubin GPU uses the GR100 chip built on the Rubin architecture, manufactured on a 3 nm process at TSMC. The die contains 336,000 million transistors on a 1456 mm² area, yielding a transistor density of 230.8M per mm². The NVIDIA die is approximately 6.25 times larger in area and holds approximately 9.9 times more transistors, with a roughly 1.6 times higher transistor density.

The AMD part is classified as a Console GPU (AMD) generation, while the NVIDIA part is classified as a Server Rubin (Rxx) generation. The AMD part has no predecessor or successor listed. The NVIDIA part lists its predecessor as Server Blackwell and no successor. The AMD part has a release date of 2025-10-15, while the NVIDIA part has a release date of 2025-12-31. Both parts are marked as Active in production status.

The AMD part uses 1024 shading units, 64 TMUs, and 48 ROPs, with 16 RT cores and no tensor cores. The NVIDIA part uses 28672 shading units, 896 TMUs, and 24 ROPs, with no RT cores listed and 896 tensor cores. The shading unit count differs by a factor of 28, while the TMU count differs by a factor of 14. The ROP count is lower on the NVIDIA part, which explains its lower pixel rate.

Memory architecture differs fundamentally. The AMD part uses LPDDR5X on a 256-bit bus with 16 GB capacity. The NVIDIA part uses HBM4 on a 16384-bit bus with 288 GB capacity. The bus width differs by a factor of 64, which directly drives the bandwidth difference. The memory clock on the AMD part is 1000 MHz with 8 Gbps effective, while the NVIDIA part runs at 2695 MHz with 10.8 Gbps effective.

The power envelope differs substantially. The AMD part has a TDP of 28 W and no power connectors. The NVIDIA part has a TDP of 2300 W, requires a suggested PSU of 2700 W, and uses an SXM Module slot width. The NVIDIA part also specifies a PCIe 6.0 x16 bus interface, while the AMD part lists no bus interface. Display outputs also differ: the AMD part has 1x USB Type-C, while the NVIDIA part has no outputs.

API support reflects the different target markets. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for conventional graphics API workloads.
