AMD Ryzen Z2 GPU vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries for the AMD Ryzen Z2 GPU and the NVIDIA N1X 48SM. Both products sit at the 50th percentile against all GPUs in the database, with an average benchmark score of zero for each. The wins columns for both products are empty, indicating that neither part has a measured victory in any comparative test suite. This absence of empirical results means the comparison must rely entirely on architectural specifications and derived performance metrics.

The raw throughput figures, however, reveal a substantial gap in computational capacity. The NVIDIA N1X 48SM delivers 28.83 TFLOPS of FP32 performance, which is 3.48 times the 8.294 TFLOPS produced by the AMD Ryzen Z2 GPU. The same ratio applies to FP16 workloads, as both parts operate at a 1:1 FP32 to FP16 ratio. Texture throughput shows an even wider disparity: the NVIDIA part achieves 900.9 GTexel/s against 129.6 GTexel/s for the AMD chip, a 6.95-fold advantage. Pixel throughput is comparatively closer, with the NVIDIA part at 112.6 GPixel/s versus 86.40 GPixel/s for the AMD part, a 1.30-fold lead.

Memory bandwidth tells a similar story. The NVIDIA N1X 48SM reaches 273.2 GB/s through a 256 bit interface, while the AMD Ryzen Z2 GPU manages 119.9 GB/s over a 128 bit bus. That is a 2.28-fold difference in raw bandwidth. The NVIDIA part also carries 128 GB of LPDDR5X memory, eight times the 16 GB found on the AMD part. Clock speeds run in the AMD part's favor at the top end: the AMD boost clock of 2700 MHz exceeds the NVIDIA boost of 2346 MHz by 15.1%. Base clocks also favor AMD, at 800 MHz versus 741 MHz, a 7.96% lead. Memory clock rates differ as well, with the NVIDIA part running at 1067 MHz (8.5 Gbps effective) compared to 937 MHz (7.5 Gbps effective) for the AMD part.

Architecture Differences

The two chips come from different foundries and process nodes. The AMD Ryzen Z2 GPU uses the Hawk Point chip built on TSMC's 4 nm process, with 25,390 million transistors packed into a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The NVIDIA N1X 48SM uses the GB20B chip on a TSMC 5 nm process, with a larger 382 mm² die. Transistor counts and density figures are not recorded for the NVIDIA part.

Architecturally, the AMD part uses RDNA 3.0, while the NVIDIA part uses Blackwell 2.0. The AMD chip belongs to the Console GPU generation, and the NVIDIA chip belongs to the Blackwell IGP (N1x) generation. The NVIDIA part is classified as an integrated graphics product (IGP) with a PCIe 5.0 x16 bus interface, whereas the AMD part lists no bus interface. The AMD part's power connectors are recorded as "None" with a 28 W TDP; the NVIDIA part's TDP is unknown, but it also has no power connectors.

Compute resource counts differ sharply. The AMD Ryzen Z2 GPU has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The NVIDIA N1X 48SM has 6,144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The NVIDIA part thus has 8 times the shading units, 8 times the TMUs, 1.5 times the ROPs, and 4 times the ray tracing cores. The NVIDIA part also has a dedicated tensor core array that the AMD part lacks entirely.

API support diverges completely. The AMD part lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists "N/A" for DirectX, OpenGL, and Vulkan, which suggests its API surface is either not yet characterized or handled through a different software stack. Display outputs also differ: the AMD part has one USB Type-C output, while the NVIDIA part has one HDMI output.

Memory configuration is another clear differentiator. The AMD part uses 16 GB of LPDDR5X on a 128 bit bus. The NVIDIA part uses 128 GB of LPDDR5X on a 256 bit bus. The effective memory speed is higher on the NVIDIA part as well, at 8.5 Gbps versus 7.5 Gbps.

Release timing places the two parts in different windows. The AMD Ryzen Z2 GPU has a release date of 2024-12-31, while the NVIDIA N1X 48SM is dated 2026-05-31. Both are listed as Active in production status. Neither part has a recorded predecessor or successor, and neither has a launch MSRP in the database.

The Verdict

The data indicates a decisive specification advantage for the NVIDIA N1X 48SM across nearly every measured metric. It leads in shading units, texture units, ROPs, ray tracing cores, tensor cores, FP32 throughput, FP16 throughput, texture rate, pixel rate, memory capacity, memory bus width, and memory bandwidth. The AMD Ryzen Z2 GPU leads only in base clock, boost clock, and transistor density, and it holds a 28 W TDP figure that the NVIDIA part does not have recorded. The AMD part also has a full conventional API set, while the NVIDIA part's APIs are marked N/A.

The 28.83 TFLOPS FP32 result for the NVIDIA part against 8.294 TFLOPS for the AMD part makes the performance class difference clear. The NVIDIA part is built for a much higher workload ceiling, and the 128 GB memory pool supports that positioning. The AMD part, with its 16 GB memory and 119.9 GB/s bandwidth, fits a more constrained role.

For users whose applications rely on conventional graphics APIs such as DirectX 12 Ultimate, OpenGL 4.6, or Vulkan 1.4, the AMD part is the only one of the two with recorded support. The NVIDIA part's N/A entries in those categories mean no compatibility data exists in the database. That makes the choice dependent on software stack requirements, not just raw throughput.

The AMD part also stands out on power. Its 28 W TDP is documented, while the NVIDIA part has no TDP recorded. The AMD part's smaller die (178 mm² versus 382 mm²) and higher transistor density (142.6M per mm² versus no recorded value) indicate a more compact implementation.

Where Each One Wins

The AMD Ryzen Z2 GPU wins in clock speed territory. Its base clock of 800 MHz and boost clock of 2700 MHz both exceed the NVIDIA part's 741 MHz and 2346 MHz. That higher clock rate, combined with a 28 W TDP, makes it the more efficient per-watt option in the recorded data, though no power figure exists for the NVIDIA part to complete the comparison. The AMD part also wins on transistor density, at 142.6 million transistors per square millimeter, and on its smaller die size of 178 mm² versus 382 mm².

The AMD part is also the only one with conventional graphics API support in the database. DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 are all listed for the AMD Ryzen Z2 GPU, while the NVIDIA N1X 48SM shows N/A for each. For any workload that requires those APIs, the AMD part is the only viable choice between the two.

The NVIDIA N1X 48SM wins in every raw compute category. Its 6,144 shading units outnumber the AMD part's 768 by a factor of 8. Its 384 TMUs outnumber the AMD part's 48 by the same factor. Its 48 ROPs exceed the AMD part's 32. Its 48 ray tracing cores quadruple the AMD part's 12. Its 192 tensor cores have no counterpart on the AMD part. FP32 throughput sits at 28.83 TFLOPS, 3.48 times the AMD part's 8.294 TFLOPS. Texture rate reaches 900.9 GTexel/s, 6.95 times the AMD part's 129.6 GTexel/s. Pixel rate hits 112.6 GPixel/s, 1.30 times the AMD part's 86.40 GPixel/s.

Memory capacity and bandwidth also belong to the NVIDIA part. The 128 GB pool is eight times the AMD part's 16 GB. The 273.2 GB/s bandwidth is 2.28 times the AMD part's 119.9 GB/s. The 256 bit bus doubles the AMD part's 128 bit interface. The NVIDIA part's effective memory speed of 8.5 Gbps also beats the AMD part's 7.5 Gbps.

The NVIDIA part further distinguishes itself with a PCIe 5.0 x16 bus interface, while the AMD part records no bus interface at all. The NVIDIA part's IGP classification and HDMI output contrast with the AMD part's USB Type-C output. The NVIDIA part also has a later release date, 2026-05-31 versus 2024-12-31.

In workload terms, the NVIDIA part is positioned for memory-heavy and compute-heavy tasks that can use its 128 GB pool, 192 tensor cores, and 28.83 TFLOPS. The AMD part is positioned for conventional API graphics workloads at a much lower power envelope, with its 28 W TDP and full DirectX, OpenGL, and Vulkan support. The absence of head-to-head benchmarks means no measured win count exists, but the specification sheet alone gives the NVIDIA part a clear lead in raw capability across nearly all categories.
