AMD Ryzen Z2 Go GPU vs NVIDIA GeForce RTX 4050 Mobile Comparison

The Verdict

The recorded data positions the NVIDIA GeForce RTX 4050 Mobile as the substantially stronger performer. Its average benchmark score of 19,049 places it in the 63rd percentile of all GPUs, while the AMD Ryzen Z2 Go GPU sits at the 50th percentile with no recorded benchmark scores in the database. The RTX 4050 Mobile delivers 8.986 TFLOPS of FP32 compute, more than double the 4.147 TFLOPS of the AMD part. This is a clear performance hierarchy: the NVIDIA solution is the primary choice for workloads requiring higher raw throughput, while the AMD chip is oriented toward low-power, integrated-class operation.

The RTX 4050 Mobile also has a decisive architectural advantage with Ada Lovelace, a 5 nm process, and dedicated RT and Tensor cores. The Ryzen Z2 Go GPU uses older RDNA 2.0 architecture on a 6 nm node. For any workload that leans on ray tracing, AI acceleration, or general compute density, the NVIDIA part is the data-backed selection. The AMD GPU is the option for designs where the 28 W power envelope and integrated form factor matter more than peak performance.

Where Each One Wins

The NVIDIA GeForce RTX 4050 Mobile wins in raw compute, memory bandwidth, and feature support. Its FP32 throughput of 8.986 TFLOPS is more than twice the AMD part's 4.147 TFLOPS. Texture rate measures 140.4 GTexel/s versus 129.6 GTexel/s, a narrower but still positive margin. Memory bandwidth is 192.0 GB/s on a 96-bit GDDR6 interface, compared to 102.4 GB/s on a 128-bit LPDDR5 bus. The NVIDIA chip also carries 80 Tensor cores and 20 RT cores, enabling hardware-accelerated ray tracing and AI workloads that the AMD GPU cannot match with its 12 RT cores and no tensor hardware.

The AMD Ryzen Z2 Go GPU wins in memory capacity and power efficiency. It offers 16 GB of LPDDR5 memory versus 6 GB of GDDR6, a substantial advantage for capacity-sensitive tasks. Its 28 W TDP is well below the 50 W TDP of the NVIDIA part, making it the appropriate choice for fanless or ultra-compact systems. The AMD chip also has a higher boost clock at 2700 MHz versus 1755 MHz, and it supports a 2:1 FP16 rate of 8.294 TFLOPS, which is close to its FP32 value, though NVIDIA's FP16 matches its FP32 at 8.986 TFLOPS.

Architecture Differences

The AMD Ryzen Z2 Go GPU is built on the Rembrandt+ chip using RDNA 2.0 architecture, fabricated by TSMC on a 6 nm process. The die contains 13,100 million transistors across 208 mm², yielding a transistor density of 63.0M per mm². Its compute configuration includes 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The memory subsystem uses 16 GB of LPDDR5 on a 128-bit bus, with 102.4 GB/s of bandwidth. Base clock is 800 MHz with a boost of 2700 MHz. The power envelope is 28 W, and the sole display output is a single USB Type-C port. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The NVIDIA GeForce RTX 4050 Mobile is built on the AD107 chip using Ada Lovelace architecture, also fabricated by TSMC but on a 5 nm process. The die packs 18,900 million transistors into 159 mm², for a density of 118.9M per mm². The compute layout is far larger: 2,560 shading units, 80 TMUs, 48 ROPs, 20 RT cores, and 80 Tensor cores. Memory is 6 GB of GDDR6 on a 96-bit bus, delivering 192.0 GB/s. Base clock is 1455 MHz with a boost of 1755 MHz. TDP is 50 W. It connects via PCIe 4.0 x8 and has no fixed display outputs, as they are portable device dependent. It also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The node difference is central: 5 nm versus 6 nm gives NVIDIA a density advantage of 118.9M versus 63.0M transistors per mm². The NVIDIA chip also has a much higher base clock, 1455 MHz versus 800 MHz, which contributes to its higher sustained throughput. The AMD part compensates with a higher boost clock and double the memory capacity, but its lower shading unit count and lack of Tensor cores limit its compute ceiling.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Ryzen Z2 Go GPU and the NVIDIA GeForce RTX 4050 Mobile. The wins count is 0 for each side. However, the NVIDIA part has a full set of recorded benchmark scores, while the AMD part has none. This absence of data for the AMD GPU is itself a significant finding: the database cannot confirm any measured performance for the Ryzen Z2 Go GPU, whereas the RTX 4050 Mobile has multiple scores across Geekbench and Passmark suites.

The RTX 4050 Mobile's average benchmark score is 19,049, with individual results including 74,748 in Geekbench OpenCL and 75,235 in Geekbench Vulkan. In Passmark tests, it scores 14,423 in G3D, 5,947 in GPU Compute, 633 in G2D, 184 in DirectX 9, 130 in DirectX 11, 79 in DirectX 10, and 61 in DirectX 12. These numbers place it at the 63rd percentile of all GPUs. Its nearest rivals in the database are the AMD Radeon RX 6600 with an average score of 19,036 and a 0.1% delta, the NVIDIA Quadro K6000 at 19,030 with a 0.1% delta, the NVIDIA RTX 2000 Ada Generation at 18,954 with a 0.5% delta, and the NVIDIA Tesla K20m at 19,089 with a -0.2% delta. This means the RTX 4050 Mobile performs essentially on par with a desktop Radeon RX 6600, within a tenth of a percent.

The AMD Ryzen Z2 Go GPU has no comparable benchmark records. Its percentile of 50 is based on its specification profile rather than measured tests. The only quantitative data available are its compute rates: 4.147 TFLOPS FP32, 8.294 TFLOPS FP16, 129.6 GTexel/s texture rate, and 86.40 GPixel/s pixel rate. Against the RTX 4050 Mobile's 8.986 TFLOPS FP32, 140.4 GTexel/s texture rate, and 84.24 GPixel/s pixel rate, the AMD chip is roughly half as fast in FP32, slightly slower in texturing, and marginally faster in pixel fill. The NVIDIA part also has a 1:1 FP16 rate at 8.986 TFLOPS, versus the AMD part's 2:1 rate at 8.294 TFLOPS, meaning NVIDIA's FP16 throughput is higher and does not sacrifice half-rate execution.

In terms of memory, the RTX 4050 Mobile's GDDR6 at 192.0 GB/s provides 87.5% more bandwidth than the AMD part's LPDDR5 at 102.4 GB/s, despite the AMD chip having a wider 128-bit bus. The NVIDIA part's narrower 96-bit bus is compensated by faster memory clocks and GDDR6 efficiency. For compute-heavy workloads, the RTX 4050 Mobile leads decisively. For capacity-heavy workloads, the Ryzen Z2 Go GPU's 16 GB pool is the clear advantage, though its lower bandwidth may bottleneck large data sets.

The architecture gap reinforces the benchmark picture. NVIDIA's Ada Lovelace on 5 nm delivers 80 Tensor cores and 20 RT cores, enabling features the AMD RDNA 2.0 part cannot offer. The AMD chip's 12 RT cores support basic ray tracing, but without Tensor cores, AI-accelerated tasks such as DLSS-class upscaling are unavailable. The RTX 4050 Mobile also has a higher transistor count at 18,900 million versus 13,100 million, and a smaller die at 159 mm² versus 208 mm², illustrating the density advantage of the newer process.

The power story is the reverse. The Ryzen Z2 Go GPU draws 28 W, nearly half the 50 W of the RTX 4050 Mobile. For portable devices with strict thermal limits, the AMD part is the only viable option in this comparison. The NVIDIA part, however, occupies a different class: it is a mobile discrete GPU with a slot width of IGP, meaning it is still integrated into a board but carries a much higher performance envelope. The AMD chip has no slot width listed and uses no power connectors, consistent with a low-power embedded design. The RTX 4050 Mobile also has no power connectors, but its 50 W TDP requires more substantial cooling.

The release timeline shows the AMD part arrived later, with a release date of 2024-12-31, while the NVIDIA part launched on 2023-01-02. The NVIDIA chip has a predecessor in the GeForce 30 Mobile series and a successor in the GeForce 50 Mobile series, indicating an established product line. The AMD chip has no predecessor or successor listed, suggesting it is a standalone entry in the console GPU generation. Both are currently marked as Active in production status.
