AMD Ryzen Z2 Go GPU vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The database contains no directly paired benchmark runs between the AMD Ryzen Z2 Go GPU and the NVIDIA GeForce RTX 4080 Mobile. The AMD part has an empty benchmark list, an average benchmark score of zero, and a 50th percentile ranking across all GPUs. The NVIDIA part, by contrast, has a substantial set of recorded results. Its average benchmark score is 38135, which places it in the 81st percentile of all GPUs. This percentile gap, from 50 to 81, is the first clear indicator of the performance divide between the two.

The RTX 4080 Mobile's individual scores show strong compute performance across multiple APIs. In Geekbench OpenCL, it records 159575 points. In Geekbench Vulkan, it scores 145807. Passmark results further illustrate its capabilities: DirectX 9 at 286, DirectX 10 at 157, DirectX 11 at 244, and DirectX 12 at 96. The Passmark G3D score is 24926, while the GPU compute score is 11191. The G2D score, which reflects 2D graphics throughput, is 929.

The nearest rivals listed for the RTX 4080 Mobile provide context for its standing. The NVIDIA GeForce MX570 has an average score of 38299, which is 0.4 percent lower. The NVIDIA GeForce RTX 5080 Mobile scores 38349, 0.6 percent lower. The NVIDIA GeForce RTX 4070 scores 37648, 1.3 percent higher. The NVIDIA Tesla P4 scores 37628, also 1.3 percent higher. These deltas are small, indicating that the RTX 4080 Mobile sits in a tightly contested performance band where the top contenders are within a couple of percent of each other.

Since the AMD Ryzen Z2 Go GPU has no recorded benchmark scores, the data cannot quantify its performance in any test. The comparison therefore rests on architectural specifications and the NVIDIA part's measured results. The absence of data for the AMD side is itself a finding: the database shows no evidence of its compute output, while the NVIDIA side demonstrates a clear, multi-test performance profile.

Architecture Differences

The two GPUs are built on different architectures, nodes, and designs. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip with RDNA 2.0 architecture, fabricated on a 6 nm process at TSMC. The NVIDIA GeForce RTX 4080 Mobile uses the AD104 chip with Ada Lovelace architecture, on a 5 nm process, also at TSMC. The process node difference, 6 nm versus 5 nm, gives the NVIDIA part a denser transistor layout.

Transistor counts diverge sharply. The AMD chip integrates 13,100 million transistors on a die size of 208 mm², yielding a transistor density of 63.0 million per mm². The NVIDIA chip contains 35,800 million transistors on a 294 mm² die, with a density of 121.8 million per mm². The NVIDIA die is larger but carries nearly three times the transistor count, and its density is roughly double.

Memory systems are fundamentally different. The AMD GPU uses 16 GB of LPDDR5 on a 128 bit bus, with memory clock at 800 MHz and 6.4 Gbps effective, producing 102.4 GB/s of bandwidth. The NVIDIA GPU uses 12 GB of GDDR6 on a 192 bit bus, with memory clock at 2250 MHz and 18 Gbps effective, producing 432.0 GB/s. The NVIDIA part has a wider bus, faster memory, and more than four times the bandwidth.

Compute resources show a large gap. The AMD GPU has 768 shading units, 48 texture mapping units, 32 raster output units, and 12 ray tracing cores. It has no tensor cores. The NVIDIA GPU has 7424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores. The shading unit count alone is nearly ten times higher on the NVIDIA side.

Clock speeds tell a different story. The AMD GPU has a base clock of 800 MHz and a boost clock of 2700 MHz. The NVIDIA GPU has a base clock of 1290 MHz and a boost clock of 1665 MHz. The AMD part boosts much higher, but the NVIDIA part starts from a higher base. The resulting throughput figures favor NVIDIA decisively. The AMD GPU delivers 4.147 TFLOPS of FP32 and 8.294 TFLOPS of FP16 with a 2:1 ratio. The NVIDIA GPU delivers 24.72 TFLOPS of FP32 and 24.72 TFLOPS of FP16 with a 1:1 ratio. Pixel and texture rates follow suit: AMD at 86.40 GPixel/s and 129.6 GTexel/s, NVIDIA at 133.2 GPixel/s and 386.3 GTexel/s.

Power envelopes differ by a wide margin. The AMD GPU has a TDP of 28 W, while the NVIDIA GPU has a TDP of 110 W. Both use no power connectors, and the NVIDIA part is classified as an IGP with a PCIe 4.0 x16 bus interface. The AMD part lists no bus interface. Display outputs also differ: the AMD GPU has a single USB Type-C output, while the NVIDIA GPU's outputs are described as portable device dependent.

Where Each One Wins

The NVIDIA GeForce RTX 4080 Mobile wins in every measurable category where data exists. Its compute scores, memory bandwidth, shading resources, and raw throughput all exceed the AMD Ryzen Z2 Go GPU. The RTX 4080 Mobile's 432.0 GB/s bandwidth versus 102.4 GB/s on the AMD side indicates a major advantage in memory-bound workloads. Its 24.72 TFLOPS FP32 versus 4.147 TFLOPS suggests roughly six times the raw compute throughput.

The AMD Ryzen Z2 Go GPU does have structural advantages that could matter in specific use cases. Its 28 W TDP versus 110 W means it draws far less power. Its 16 GB memory capacity exceeds the NVIDIA's 12 GB, which could benefit workloads that need larger memory pools rather than faster ones. Its higher boost clock of 2700 MHz versus 1665 MHz suggests it can spike to higher frequencies under short bursts, though the NVIDIA part compensates with far more parallel units.

The NVIDIA GPU's tensor cores, 232 of them, provide dedicated hardware for AI workloads that the AMD part lacks entirely. Its 58 RT cores versus 12 give it a substantial edge in ray tracing tasks. The AMD part has no tensor core count listed, meaning the database records no such capability. For any workload that leverages tensor operations or heavy ray tracing, the NVIDIA part is the only one with substantial dedicated hardware.

The AMD part's 50th percentile ranking versus the NVIDIA's 81st percentile places them in different tiers of the overall GPU landscape. The data shows that the RTX 4080 Mobile competes with the RTX 4070, RTX 5080 Mobile, MX570, and Tesla P4, all within 1.3 percent of its average score. The AMD part has no nearest rivals listed, reinforcing that the database has no comparable measurements for it.

The Verdict

The data points to a clear performance hierarchy. The NVIDIA GeForce RTX 4080 Mobile occupies the 81st percentile and has a full set of benchmark results, while the AMD Ryzen Z2 Go GPU sits at the 50th percentile with no recorded benchmarks. The NVIDIA part's 24.72 TFLOPS FP32, 432.0 GB/s bandwidth, 7424 shading units, and 232 tensor cores give it overwhelming advantages in compute, memory, and feature support.

The AMD Ryzen Z2 Go GPU offers a lower power envelope at 28 W, more memory capacity at 16 GB, and a higher boost clock at 2700 MHz, but none of these compensate for the absence of measured performance. The RTX 4080 Mobile's nearest rivals all sit within 1.3 percent of its average score, showing it is a competitive mid-to-high tier mobile part. The AMD part has no rival comparisons, which limits any quantitative assessment.

For users who need documented compute performance, the RTX 4080 Mobile is the only one with evidence in the database. For users who prioritize power efficiency and larger memory capacity, the AMD part has structural appeal, but the lack of benchmark data means its real-world performance cannot be verified from these records. The verdict from the data is straightforward: the NVIDIA part wins on every measurable metric, and the AMD part remains unquantified.
