AMD Ryzen Z2 Go GPU vs NVIDIA GeForce RTX 4060 Mobile Comparison

The AMD Ryzen Z2 Go GPU and the NVIDIA GeForce RTX 4060 Mobile occupy different tiers of the mobile graphics landscape, with distinct architectural approaches and performance profiles. The data in the database shows the RTX 4060 Mobile holds a commanding lead in raw compute and rendering benchmarks, while the Z2 Go offers a much lower power envelope and a larger memory pool. This analysis breaks down where each part wins, the underlying silicon differences, and the exact benchmark gaps recorded.

Where Each One Wins

The RTX 4060 Mobile is the clear winner in every recorded benchmark category. The database lists nine benchmark scores for the RTX 4060 Mobile, and all of them are substantial. Its PassMark G3D score of 17469 places it in the 67th percentile of all GPUs, while the Z2 Go has no recorded benchmark scores and sits at the 50th percentile with an average score of zero. The RTX 4060 Mobile’s average benchmark score across all tests is 22729, a figure that reflects its strong performance in both gaming and compute workloads.

The Z2 Go’s advantage lies in its power consumption and memory capacity. With a TDP of 28 W compared to the RTX 4060 Mobile’s 115 W, the Z2 Go consumes a fraction of the power. It also features 16 GB of LPDDR5 memory versus the RTX 4060 Mobile’s 8 GB of GDDR6. For workloads that need large memory allocations, such as high-resolution texture sets or certain compute tasks, the Z2 Go’s capacity is a differentiating factor. However, the bandwidth is far lower: the Z2 Go delivers 102.4 GB/s, while the RTX 4060 Mobile reaches 256.0 GB/s. The RTX 4060 Mobile also wins on raw throughput metrics, including pixel rate, texture rate, and FP32 compute, as detailed in the specification differences below.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip built on the RDNA 2.0 architecture, manufactured on a 6 nm process at TSMC. It packs 13,100 million transistors onto a 208 mm² die, resulting in a transistor density of 63.0M per mm². The RTX 4060 Mobile uses the AD107 chip based on the Ada Lovelace architecture, fabricated on a 5 nm process, also at TSMC. This chip contains 18,900 million transistors on a smaller 159 mm² die, giving a much higher density of 118.9M per mm². The process node advantage and denser packing allow NVIDIA to fit more compute units into a smaller area.

The compute resources differ dramatically. The Z2 Go has 768 shading units, 48 texture mapping units, and 32 raster output units. In contrast, the RTX 4060 Mobile has 3072 shading units, 96 TMUs, and 48 ROPs. The RTX 4060 Mobile also includes 24 ray tracing cores and 96 tensor cores, while the Z2 Go lists 12 ray tracing cores and no tensor cores. This means the RTX 4060 Mobile has specialized hardware for ray tracing and AI-accelerated workloads, which the Z2 Go lacks entirely. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical, but the underlying hardware capabilities are vastly different.

Clock speeds also differ. The Z2 Go has a base clock of 800 MHz and a boost clock of 2700 MHz, with memory running at 800 MHz (6.4 Gbps effective). The RTX 4060 Mobile has a higher base clock of 1545 MHz but a lower boost clock of 1890 MHz, with memory at 2000 MHz (16 Gbps effective). The Z2 Go’s higher boost clock partially compensates for its lower shader count, but the sheer number of execution units on the RTX 4060 Mobile overwhelms that advantage.

Head-to-Head Benchmarks

The database does not contain any direct head-to-head benchmark results between the Z2 Go and the RTX 4060 Mobile, as the winsA and winsB fields both show zero. However, the RTX 4060 Mobile has nine recorded benchmark scores, and the Z2 Go has none. This absence of data for the Z2 Go means the comparison relies on the RTX 4060 Mobile’s standalone scores and the theoretical specifications of the Z2 Go.

The RTX 4060 Mobile’s benchmark results demonstrate its performance tier. In Geekbench OpenCL, it scores 89420, and in Geekbench Vulkan, it scores 89569. These are compute-heavy workloads where the RTX 4060 Mobile’s 3072 shading units and 96 tensor cores provide substantial throughput. The PassMark suite shows a G3D score of 17469, a G2D score of 730, and a GPU compute score of 6816. The DirectX 10, 11, and 12 scores are 107, 157, and 73 respectively, while the DirectX 9 score is 216.

Comparing these to the Z2 Go, the FP32 compute difference is stark: 11.61 TFLOPS versus 4.147 TFLOPS, a 2.8x advantage for the RTX 4060 Mobile. The texture rate difference is 181.4 GTexel/s versus 129.6 GTexel/s, a 1.4x gap. The pixel rate is closer, with 90.72 GPixel/s versus 86.40 GPixel/s, a small 5% difference. The RTX 4060 Mobile’s memory bandwidth of 256.0 GB/s versus the Z2 Go’s 102.4 GB/s is a 2.5x gap, which directly impacts texture streaming and high-resolution rendering.

The nearest rivals for the RTX 4060 Mobile provide context for its scores. The NVIDIA GeForce RTX 2080 has an average score of 22895, which is 0.7% lower than the RTX 4060 Mobile’s 22729. The AMD Radeon RX 7700 XT scores 22549, which is 0.8% higher than the RTX 4060 Mobile. The Intel Arc B580 scores 23021, 1.3% higher, and the NVIDIA GeForce RTX 5060 Mobile scores 22435, 1.3% lower. These deltas show the RTX 4060 Mobile sits in a tight performance band, slightly below the Arc B580 and RX 7700 XT but above the RTX 5060 Mobile and RTX 2080.

For the Z2 Go, with no benchmark scores in the database, its percentile of 50 versus the RTX 4060 Mobile’s 67 indicates a lower overall standing. The Z2 Go’s 28 W TDP positions it for ultraportable or low-power devices, whereas the RTX 4060 Mobile’s 115 W TDP targets performance laptops. The Z2 Go’s 16 GB memory capacity could benefit specific workloads like large language models or high-resolution texture packs, but the bandwidth limitation of 102.4 GB/s would bottleneck such tasks compared to the RTX 4060 Mobile’s 256.0 GB/s.

The recorded data confirms the RTX 4060 Mobile as the substantially faster GPU across all measurable benchmarks. The Z2 Go’s advantages are limited to power efficiency and memory capacity, but in every throughput metric, the RTX 4060 Mobile leads by significant margins. The lack of any Z2 Go benchmark scores in the database means its practical performance cannot be quantified, but the specification sheet alone shows a large gap in compute resources and memory bandwidth.
