AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 4080 SUPER Comparison

The Verdict

The recorded data shows two GPUs with entirely different design intents. The AMD Ryzen Z2 GPU is a console-class, 28 W part with a 50th percentile ranking among all GPUs, while the NVIDIA GeForce RTX 4080 SUPER is a desktop flagship with an 86th percentile ranking. The RTX 4080 SUPER carries 10,240 shading units versus 768 for the Z2 GPU, and its FP32 throughput of 52.22 TFLOPS dwarfs the Z2's 8.294 TFLOPS. The RTX 4080 SUPER holds an average benchmark score of 54,209, whereas the Z2 GPU has no recorded benchmark scores in the database. Any buyer seeking raw frame rates must choose the RTX 4080 SUPER; the Z2 GPU exists for ultra-low-power embedded or handheld scenarios where its 28 W TDP and lack of power connectors are the defining traits.

Where Each One Wins

The RTX 4080 SUPER wins every measurable category where data exists. Its 3DMark Steel Nomad DX12 score of 6,600, Geekbench OpenCL score of 219,065, and Geekbench Vulkan score of 260,075 confirm dominance in synthetic workloads. Passmark results reinforce this: G3D score of 34,245, GPU compute score of 19,822, and even legacy DX9 at 381 versus nothing for the Z2 GPU. The Z2 GPU wins only in power efficiency by design: 28 W TDP versus 320 W, with no power connector required. The Z2 also uses LPDDR5X memory (937 MHz, 7.5 Gbps effective) versus GDDR6X (1438 MHz, 23 Gbps effective) on the RTX card, but that is a bandwidth loss, not a win: 119.9 GB/s versus 736.3 GB/s. The Z2 GPU's only genuine advantage is its 178 mm² die size versus 379 mm², which reflects its integrated nature, and its 4 nm process node versus 5 nm, allowing higher transistor density (142.6M per mm² versus 121.1M per mm²). But density does not translate to performance; the RTX 4080 SUPER's 45,900 million transistors deliver 6.3 times the FP32 throughput.

Architecture Differences

The Z2 GPU uses AMD's RDNA 3.0 architecture on a 4 nm TSMC process, with the chip codenamed Hawk Point. It is classified as a Console GPU (AMD) generation product. The RTX 4080 SUPER uses NVIDIA's Ada Lovelace architecture on a 5 nm TSMC process, with the AD103 chip, part of the GeForce 40-series. The Z2 has 12 RT cores and no tensor cores; the RTX 4080 SUPER has 80 RT cores and 320 tensor cores. The Z2's shading units number 768 with 48 TMUs and 32 ROPs; the RTX card has 10,240 shading units, 320 TMUs, and 112 ROPs. Pixel rate differs sharply: 86.40 GPixel/s for the Z2 versus 285.6 GPixel/s for the RTX. Texture rate: 129.6 GTexel/s versus 816.0 GTexel/s. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Memory types diverge: LPDDR5X at 16 GB with a 128-bit bus versus GDDR6X at 16 GB with a 256-bit bus. The RTX 4080 SUPER is a triple-slot card, 310 mm long, 140 mm tall, 61 mm wide, requiring a 700 W suggested PSU and a single 16-pin connector. The Z2 GPU has no slot width, dimensions, or power connectors listed, and outputs only 1x USB Type-C. The RTX card outputs 1x HDMI 2.1 and 3x DisplayPort 1.4a. The Z2 GPU was released on 2024-12-31, the RTX 4080 SUPER on 2024-01-30, and the RTX card is now end-of-life with a successor (GeForce 50) already recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen Z2 GPU and the NVIDIA GeForce RTX 4080 SUPER. The winsA and winsB fields both record zero. However, the RTX 4080 SUPER's standalone benchmark suite provides a clear performance profile. In 3DMark Steel Nomad DX12, it scores 6,600. In Geekbench, it scores 219,065 for OpenCL and 260,075 for Vulkan. Passmark results show 193 for DX10, 301 for DX11, 134 for DX12, 381 for DX9, 1,270 for G2D, 34,245 for G3D, and 19,822 for GPU compute. These scores place the RTX 4080 SUPER at the 86th percentile, with an average score of 54,209. Its nearest rival, the RTX 4080, scores 54,247, just 0.1% higher, indicating the SUPER is essentially a parity refresh. The AMD Radeon Pro W5700X, RX 6750 GRE 12 GB, and Radeon 8060S all score within 2.8% higher, meaning the RTX 4080 SUPER sits at the top of a tightly clustered performance band. The Z2 GPU, with no scores, cannot be positioned on any benchmark scale; its 8.294 TFLOPS FP32 output is 6.3 times lower than the RTX card's 52.22 TFLOPS, and its pixel rate is 3.3 times lower (86.40 versus 285.6 GPixel/s). Texture rate is 6.3 times lower (129.6 versus 816.0 GTexel/s). The RTX 4080 SUPER's 16 GB GDDR6X memory at 736.3 GB/s provides 6.1 times the bandwidth of the Z2's 16 GB LPDDR5X at 119.9 GB/s.

The data indicates a fundamental split: the Z2 GPU is a compact, low-power integrated solution with no expansion slot, while the RTX 4080 SUPER is a triple-slot, high-power discrete card. The RTX card's base clock exceeds the Z2's boost clock (2295 MHz versus 2700 MHz, with the Z2's base at 800 MHz). The RTX card's 320 tensor cores enable AI workloads, a feature entirely absent from the Z2. The RTX 4080 SUPER's 86th percentile ranking places it among the top 14% of all GPUs, whereas the Z2 GPU's 50th percentile places it exactly at the median. The RTX card's 16 GB memory matches the Z2's capacity, but the GDDR6X implementation at 23 Gbps effective offers 6.1 times the bandwidth. The Z2 GPU's 4 nm process allows 17.8% higher transistor density, but the RTX card uses 80.8% more transistors overall. The release dates differ by 11 months, with the RTX card arriving first and already moving to end-of-life status with a known successor, while the Z2 GPU remains active in production.
