AMD Ryzen Z2 Extreme GPU vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The single recorded benchmark in the database, 3DMark Steel Nomad DX12, delivers a decisive result. The AMD Ryzen Z2 Extreme GPU scores 516, while the NVIDIA GeForce RTX 5080 SUPER scores 3075. The delta is -83.2% for the AMD part, meaning the NVIDIA card delivers roughly 6 times the performance in this test. This is not a close contest by any measurable margin.

The NVIDIA part's score places it in the 19th percentile of all GPUs in the database, while the AMD part sits at the 1st percentile. The gap in percentile ranking reflects the sheer magnitude of the performance difference. The AMD Ryzen Z2 Extreme GPU's nearest rivals in the database are older discrete parts: the Intel HD Graphics P4000 scores 534 (3.4% higher), the AMD Radeon HD 6870 scores 536 (3.7% higher), and the AMD Radeon HD 6770M scores 569 (9.3% higher). The only rival the AMD part beats is the AMD Radeon HD 6750M, which scores 484, a 6.6% deficit. These are all legacy products from a previous era, which contextualizes the Ryzen Z2 Extreme GPU as a low-power integrated solution rather than a discrete performance part.

The NVIDIA GeForce RTX 5080 SUPER's nearest rivals tell a similar story from the opposite end. The NVIDIA Quadro P1000 scores 3163, which is 2.8% higher than the RTX 5080 SUPER. The Intel Arc Pro B60 scores 3182, 3.4% higher. On the losing side, the NVIDIA GeForce 820A scores 2983 (3.1% lower) and the NVIDIA GeForce GTX 860M scores 2967 (3.6% lower). These deltas are small, indicating that the RTX 5080 SUPER's raw score sits within a tight cluster of mid-range results in the database, despite its high absolute score.

Interpreting the data: the AMD part's 516 score is not merely low in absolute terms; it is also outperformed by three of its four nearest database rivals. The NVIDIA part's 3075 score is nearly 6 times higher, and its nearest rivals are all within roughly 3.5% of its score, suggesting the RTX 5080 SUPER sits at a performance plateau where small architectural differences among similar-tier parts produce only minor deltas. The head-to-head delta of -83.2% is the largest single-metric gap recorded between these two products, and no benchmark in the database favors the AMD part.

The Verdict

The data directs a clear split. The AMD Ryzen Z2 Extreme GPU is a 28 W part with a 516 average benchmark score, placing it at the 1st percentile of all GPUs. Its rivals are all older, lower-tier discrete GPUs, and it only edges out the AMD Radeon HD 6750M. The NVIDIA GeForce RTX 5080 SUPER, by contrast, posts a 3075 average score, sits at the 19th percentile, and beats the AMD part by 83.2% in the only shared benchmark. The RTX 5080 SUPER also carries a 415 W TDP, a dual-slot cooler, and a 16-pin power connector, all consistent with a high-end discrete card. The AMD part uses no power connector and is designed around a 28 W envelope, consistent with an integrated-class GPU.

For scenarios where the 3DMark Steel Nomad DX12 result is the relevant workload, the RTX 5080 SUPER is the only defensible choice. Its score is 2559 points higher, and its nearest rivals in the database are all within a few percent, meaning it is not an outlier in its class but a consistent mid-range performer. The AMD part's score is lower than three of its four nearest rivals, which places it at the bottom of an already low tier. The data does not support any scenario where the Ryzen Z2 Extreme GPU outperforms the RTX 5080 SUPER in this benchmark. The verdict is therefore unambiguous: the RTX 5080 SUPER is the superior choice for any application that relies on the measured DX12 workload, while the Ryzen Z2 Extreme GPU's only advantage in the recorded data is its dramatically lower power draw.

Architecture Differences

The two parts target entirely different design philosophies. The AMD Ryzen Z2 Extreme GPU uses the Strix Point chip built on the RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip built on the Blackwell 2.0 architecture, also manufactured at TSMC but on a 5 nm process. The node difference is notable: the AMD part uses a denser 4 nm process, achieving a transistor density of 145.9M per mm², while the NVIDIA part uses 5 nm with a density of 120.6M per mm².

The transistor counts reflect the scale difference. The AMD chip integrates 34,000 million transistors on a 233 mm² die. The NVIDIA chip integrates 45,600 million transistors on a 378 mm² die. Despite the smaller process node, the AMD die is physically smaller and holds fewer transistors, confirming its position as a low-power, compact design. The NVIDIA die is 145 mm² larger and holds 11,600 million more transistors, which explains the massive gap in shading units, texture mapping units, and ray tracing cores.

The memory subsystems are fundamentally different. The AMD part uses 16 GB of LPDDR5X on a 128-bit bus, delivering 128.0 GB/s of bandwidth. The NVIDIA part uses 24 GB of GDDR7 on a 256-bit bus, delivering 1.02 TB/s. The bandwidth difference is a factor of 8, which directly affects fill-rate-heavy workloads. The AMD part's effective memory clock is 8 Gbps, while the NVIDIA part's is 32 Gbps, a 4x difference in per-pin data rate.

The core configurations are equally divergent. The AMD part has 1024 shading units, 64 TMUs, 48 ROPs, and 16 ray tracing cores. The NVIDIA part has 10,752 shading units, 336 TMUs, 112 ROPs, and 84 ray tracing cores. The NVIDIA part also includes 336 tensor cores, while the AMD part lists none. The pixel rate difference is 129.6 GPixel/s versus 293.1 GPixel/s, and the texture rate difference is 172.8 GTexel/s versus 879.3 GTexel/s. FP32 compute is 5.530 TFLOPS for the AMD part versus 56.28 TFLOPS for the NVIDIA part, a 10.2x gap. FP16 performance is identical to FP32 on both parts at a 1:1 ratio.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is equivalent. The AMD part is classified as a Console GPU generation product, while the NVIDIA part is a GeForce 50-series product. The NVIDIA part uses a PCIe 5.0 x16 bus interface, while the AMD part lists no bus interface in the database. Display outputs also differ: the AMD part offers a single USB Type-C output, while the NVIDIA part offers one HDMI 2.1b and three DisplayPort 2.1b outputs.
