AMD Ryzen Z2 Go GPU vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

AMD’s Ryzen Z2 Go GPU is a compact console-class part built around RDNA 2.0, using a 6 nm TSMC process with 13,100 million transistors on a 208 mm² die. The NVIDIA RTX 5000 Mobile Ada Generation is a far larger mobile workstation GPU, built on the Ada Lovelace architecture using a 5 nm TSMC process with 45,900 million transistors on a 379 mm² die. The recorded data shows two very different design goals: the Ryzen Z2 Go targets low-power integrated graphics duties, while the RTX 5000 Mobile is a high-end discrete solution for professional laptops.

Head-to-Head Benchmarks

The benchmark database contains a single recorded result for the RTX 5000 Mobile Ada Generation: a 3DMark Steel Nomad DX12 score of 3596. The Ryzen Z2 Go GPU has no recorded benchmark scores in the database, so direct head-to-head comparisons rely on the RTX 5000 Mobile’s nearest rivals to contextualize its performance. The RTX 5000 Mobile’s score places it in the 21st percentile of all GPUs in the database, meaning roughly four-fifths of recorded graphics processors outperform it in this specific workload. That positioning is notable for a part with such high theoretical compute figures.

The nearest rival for the RTX 5000 Mobile is the NVIDIA GeForce GT 545, which averages 3594 points, a difference of 0.1%. This is effectively a statistical tie, with the RTX 5000 Mobile holding a marginal advantage. The NVIDIA GeForce GT 735M scores 3616, which is 0.6% higher than the RTX 5000 Mobile, so the RTX 5000 Mobile falls slightly behind that older mobile part. The NVIDIA GeForce GTX 1050 averages 3629 points, 0.9% ahead of the RTX 5000 Mobile. The AMD Radeon HD 6770 leads this group with 3649 points, 1.5% ahead of the RTX 5000 Mobile.

These delta values are small, all within a 1.5% band, which indicates that the RTX 5000 Mobile’s recorded performance in Steel Nomad is closely clustered with several older, much lower-end GPUs. The data does not show the RTX 5000 Mobile dominating any of its nearest rivals; instead, it sits in the middle of a pack of legacy desktop and mobile parts. For the Ryzen Z2 Go, the absence of benchmark entries means no measured score exists to compare directly. The database records zero wins for the Ryzen Z2 Go and zero wins for the RTX 5000 Mobile in head-to-head testing.

The RTX 5000 Mobile’s theoretical specifications suggest far higher throughput than its nearest rivals. Its FP32 compute is 41.15 TFLOPS, its texture rate is 643.0 GTexel/s, and its pixel rate is 236.9 GPixel/s. Yet its recorded Steel Nomad score of 3596 does not reflect that theoretical advantage, instead aligning with the GT 545, GT 735M, GTX 1050, and HD 6770. This gap between raw specification and measured benchmark performance is the central finding in the recorded data.

The Ryzen Z2 Go, by contrast, has no measured benchmark result, so its real-world standing cannot be quantified from the database. Its theoretical FP32 output is 4.147 TFLOPS, which is roughly one-tenth of the RTX 5000 Mobile’s 41.15 TFLOPS. Its texture rate of 129.6 GTexel/s and pixel rate of 86.40 GPixel/s are also far lower. However, the RTX 5000 Mobile’s own benchmark result shows that high theoretical numbers do not automatically translate into top-tier measured performance.

The Verdict

The data points to different buyers for each part. The Ryzen Z2 Go GPU is a low-power integrated solution with a 28 W TDP, designed for compact consoles and handheld-style devices. Its 16 GB of LPDDR5 memory on a 128 bit bus delivers 102.4 GB/s of bandwidth, which is modest but workable for its intended class. The RTX 5000 Mobile Ada Generation is a 120 W mobile discrete GPU with 16 GB of GDDR6 memory on a 256 bit bus, delivering 576.0 GB/s of bandwidth. That is over five times the memory bandwidth of the Ryzen Z2 Go.

From the recorded benchmark data alone, the RTX 5000 Mobile cannot be recommended as a high performer. Its 21st percentile ranking and its 0.1% to 1.5% distance from the GT 545, GT 735M, GTX 1050, and HD 6770 place it in the lower quarter of the database for Steel Nomad. The Ryzen Z2 Go has no recorded score, so no measured conclusion can be drawn about its performance. Buyers who prioritize measured results should note that only the RTX 5000 Mobile has a recorded score, and that score is not competitive with the broader database.

For users who need a professional mobile GPU with high memory bandwidth and a large transistor budget, the RTX 5000 Mobile offers the specifications to handle heavy workloads, assuming the benchmark discrepancy is an anomaly of the single recorded test. For users building a low-power system, the Ryzen Z2 Go uses less than a quarter of the RTX 5000 Mobile’s power draw, at 28 W versus 120 W, and requires no power connectors. The RTX 5000 Mobile also requires no external power connectors according to the database, but its TDP is much higher.
