Architecture Differences

The architectural divide between these two processors is substantial across every major subsystem. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip, a 6 nm TSMC design carrying 13,100 million transistors on a 208 mm² die. The NVIDIA N1X 48SM uses the GB20B chip, a 5 nm TSMC design occupying a larger 382 mm² die, though the transistor count remains unknown in the database.

The compute core layout differs dramatically. AMD configures 768 shading units into its RDNA 2.0 design, paired with 48 texture mapping units and 32 render output units. NVIDIA's Blackwell 2.0 architecture deploys 6144 shading units, 384 TMUs, and 48 ROPs. The NVIDIA part also includes 192 tensor cores alongside 48 RT cores, while AMD offers only 12 RT cores and no tensor hardware.

Memory architecture follows a similar divergence. AMD uses 16 GB of LPDDR5 on a 128-bit bus, yielding 102.4 GB/s of bandwidth. NVIDIA uses 128 GB of LPDDR5X on a 256-bit bus, yielding 273.2 GB/s. The NVIDIA memory operates at 1067 MHz (8.5 Gbps effective) versus AMD's 800 MHz (6.4 Gbps effective). This gives NVIDIA a 2.67x bandwidth advantage.

Clock behavior also differs. The AMD GPU boosts to 2700 MHz from an 800 MHz base, a 3.375x uplift. The NVIDIA GPU boosts to 2346 MHz from a 741 MHz base, a 3.17x uplift. Despite lower peak clocks, the NVIDIA part achieves far higher throughput due to its 8x shading unit count.

Pixel and texture throughput reflect these core differences. AMD produces 86.40 GPixel/s and 129.6 GTexel/s. NVIDIA produces 112.6 GPixel/s and 900.9 GTexel/s. The texture rate advantage for NVIDIA is particularly pronounced at 6.95x, driven by the 8x TMU count partially offset by lower boost clocks.

The power envelope is one area where AMD holds a definitive specification. The Ryzen Z2 Go GPU draws 28 W TDP. The NVIDIA N1X 48SM has an unknown TDP, but its classification as an IGP with no power connectors suggests an integrated design. The AMD part also has no power connectors listed.

The bus interface and display outputs further separate the two. NVIDIA specifies PCIe 5.0 x16, while AMD lists no bus interface. NVIDIA provides a single HDMI output, AMD provides a single USB Type-C output. API support also differs: AMD lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while NVIDIA lists N/A for all three in the database.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins in efficiency-oriented scenarios. Its 28 W TDP makes it suitable for power-constrained environments, and its smaller 208 mm² die with 13,100 million transistors on 6 nm suggests a more compact implementation. The lower memory capacity of 16 GB still provides substantial storage for graphics data, and the 800 MHz base clock with 2700 MHz boost shows a wide dynamic range for power management.

The NVIDIA N1X 48SM wins in raw compute scenarios. Its 28.83 TFLOPS FP32 performance represents a 6.95x advantage over the AMD part. The 128 GB memory capacity is 8x larger, and the 273.2 GB/s bandwidth is 2.67x higher. The 192 tensor cores provide dedicated AI acceleration hardware that AMD lacks entirely. The 48 RT cores versus 12 give NVIDIA a 4x advantage in ray tracing hardware resources.

For texture-heavy workloads, NVIDIA's 900.9 GTexel/s versus AMD's 129.6 GTexel/s shows a 6.95x advantage. For pixel processing, NVIDIA's 112.6 GPixel/s versus AMD's 86.40 GPixel/s represents a 1.3x advantage, the smallest relative gap among the compute metrics. This suggests that ROP-bound workloads see the least separation between the two.

The AMD part wins on transistor density, achieving 63.0M transistors per mm² versus NVIDIA's unknown figure but larger die. The AMD release date of late 2024 predates the NVIDIA mid-2026 release, indicating earlier availability. The AMD part also lists complete API support while NVIDIA lists N/A, which may affect software compatibility depending on the system context.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries between these two GPUs, and both parts show zero wins in their respective benchmark categories. The avgBenchmarkScore for both is 0, and the percentileVsAllGpus for both is 50. This means the recorded data does not include comparative performance measurements, so the analysis relies entirely on the specification-level differences.

The FP32 compute comparison provides the clearest separation. The NVIDIA N1X 48SM delivers 28.83 TFLOPS, which is 6.95x the AMD Ryzen Z2 Go GPU's 4.147 TFLOPS. In FP16, the NVIDIA part delivers 28.83 TFLOPS while AMD achieves 8.294 TFLOPS, a 3.48x advantage. The 1:1 FP16 ratio on NVIDIA versus 2:1 on AMD shows different precision strategies.

Texture throughput shows the largest multiplicative gap among the measured rates. NVIDIA's 900.9 GTexel/s is 6.95x AMD's 129.6 GTexel/s. This difference stems from the 8x TMU count (384 versus 48) partially offset by the lower NVIDIA boost clock (2346 MHz versus 2700 MHz). The pixel rate gap is smaller: NVIDIA's 112.6 GPixel/s is 1.3x AMD's 86.40 GPixel/s, driven by NVIDIA's 48 ROPs versus AMD's 32.

Memory bandwidth favors NVIDIA at 273.2 GB/s versus 102.4 GB/s, a 2.67x difference. The memory bus width doubles from 128-bit to 256-bit, and the memory type advances from LPDDR5 to LPDDR5X. The NVIDIA memory clock runs at 1067 MHz versus AMD's 800 MHz. The capacity difference is 8x: 128 GB versus 16 GB.

The die size difference is 382 mm² versus 208 mm², making the NVIDIA chip 1.84x larger. AMD packs 13,100 million transistors onto its smaller die, achieving 63.0M per mm² density. The NVIDIA transistor count is unknown, so density cannot be calculated from the database.

Clock speeds tell a mixed story. AMD has a higher base clock (800 MHz versus 741 MHz) and a higher boost clock (2700 MHz versus 2346 MHz). The AMD boost is 15.1% higher than NVIDIA's. However, the architectural scale differences overwhelm the clock advantage in every throughput metric.

Release timing separates the products by roughly 17 months, with AMD available from late December 2024 and NVIDIA from late May 2026. Both are listed as Active production status in the database.

The Verdict

The data presents two fundamentally different design philosophies. The AMD Ryzen Z2 Go GPU is a compact, power-conscious part with a 28 W TDP, a 208 mm² die, and 4.147 TFLOPS FP32 performance. The NVIDIA N1X 48SM is a large IGP with a 382 mm² die, 28.83 TFLOPS FP32, and 128 GB of memory.

For workloads that depend on FP32 throughput, texture filtering, memory bandwidth, or tensor operations, the NVIDIA N1X 48SM holds commanding leads. Its 6.95x FP32 advantage, 6.95x texture rate advantage, and 2.67x bandwidth advantage make it the choice for compute-heavy applications. The 192 tensor cores provide AI acceleration capabilities that the AMD part cannot match. The 48 RT cores versus 12 also favor NVIDIA in ray tracing scenarios.

For power-constrained or thermally limited systems, the AMD Ryzen Z2 Go GPU is the only part with a defined TDP at 28 W. Its smaller die and lower memory capacity suggest a more modest footprint. The complete API support list (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4) versus NVIDIA's N/A entries may matter for software compatibility in certain environments.

The pixel rate comparison shows the smallest relative gap at 1.3x, indicating that ROP-bound workloads see the least separation. This could mean the AMD part remains competitive in scenarios that are primarily fill-rate limited rather than shader or texture limited.

Both parts have equal percentileVsAllGpus at 50, and neither has recorded benchmark scores or nearest rivals in the database. The absence of head-to-head benchmark data means these conclusions derive exclusively from the specification-level measurements.

Users requiring maximum compute density, memory capacity, or AI features should select the NVIDIA N1X 48SM. Users prioritizing a defined low power envelope, earlier availability, or complete graphics API support should select the AMD Ryzen Z2 Go GPU. The choice hinges on whether raw throughput or power efficiency takes precedence in the target system.
