AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 4080 SUPER Comparison

# AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 4080 SUPER

The AMD Ryzen Z2 A GPU and NVIDIA GeForce RTX 4080 SUPER occupy entirely different segments of the graphics hardware landscape. The database records the RTX 4080 SUPER at the 86th percentile among all GPUs, with an average benchmark score of 54,209, while the Ryzen Z2 A GPU sits at the 50th percentile with no recorded benchmark scores. The RTX 4080 SUPER delivers 52.22 TFLOPS of FP32 compute compared to 1.638 TFLOPS for the Ryzen Z2 A GPU, a difference of roughly 32 times. These two parts are not direct competitors, but the data provides a useful study in how architectural priorities and power envelopes shape performance.

Where Each One Wins

The RTX 4080 SUPER wins every measurable category in the database. Its 10,240 shading units vastly outnumber the 512 shading units of the Ryzen Z2 A GPU. The RTX 4080 SUPER produces 285.6 GPixel/s of pixel throughput versus 25.60 GPixel/s for the Ryzen Z2 A GPU, a factor of approximately 11. Texture rate stands at 816.0 GTexel/s against 51.20 GTexel/s, a 16 times advantage. Memory bandwidth tells a similar story: 736.3 GB/s versus 102.4 GB/s, roughly seven times higher. The RTX 4080 SUPER's 80 ray tracing cores and 320 tensor cores provide dedicated hardware for workloads that the Ryzen Z2 A GPU's 8 ray tracing cores cannot match.

The Ryzen Z2 A GPU does claim one clear advantage: power consumption. Its 15 W TDP is dramatically lower than the RTX 4080 SUPER's 320 W TDP. For systems where thermal output and energy draw are primary constraints, the Ryzen Z2 A GPU is the only viable option between these two. The Ryzen Z2 A GPU also uses a single USB Type-C display output, which suits compact, portable designs, whereas the RTX 4080 SUPER offers 1x HDMI 2.1 and 3x DisplayPort 1.4a for multi-monitor desktop setups. The Ryzen Z2 A GPU measures no dimensions in the database, while the RTX 4080 SUPER is a triple-slot card at 310 mm length, 140 mm height, and 61 mm width.

Architecture Differences

The Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC. It contains 2,400 million transistors on a 163 mm² die, yielding a transistor density of 14.7 million per square millimeter. The RTX 4080 SUPER uses the AD103 chip based on Ada Lovelace architecture, built on a 5 nm process also at TSMC. It packs 45,900 million transistors into a 379 mm² die, achieving 121.1 million transistors per square millimeter. The density difference reflects the newer process node and the more complex compute layout of the Ada Lovelace design.

Memory configurations differ substantially. The Ryzen Z2 A GPU uses 16 GB of LPDDR5 on a 128-bit bus, running at 800 MHz with 6.4 Gbps effective speed. The RTX 4080 SUPER also has 16 GB, but it uses GDDR6X on a 256-bit bus at 1438 MHz with 23 Gbps effective speed. The bandwidth gap of 736.3 GB/s versus 102.4 GB/s comes from both the wider bus and the faster memory type. The Ryzen Z2 A GPU's FP16 throughput is 3.277 TFLOPS at a 2:1 ratio versus its FP32 rate, while the RTX 4080 SUPER delivers FP16 at 52.22 TFLOPS with a 1:1 ratio, meaning no rate loss for half-precision work.

The RTX 4080 SUPER includes 320 tensor cores, which the Ryzen Z2 A GPU lacks entirely. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical on paper. The RTX 4080 SUPER connects via PCIe 4.0 x16, while the Ryzen Z2 A GPU has no bus interface listed in the database. The RTX 4080 SUPER requires a 700 W suggested PSU and a 16-pin power connector, while the Ryzen Z2 A GPU lists no power connector or PSU requirement, consistent with its 15 W envelope.

The Verdict

The data shows no scenario where the Ryzen Z2 A GPU outperforms the RTX 4080 SUPER in raw graphics throughput. Every compute metric, from pixel rate to texture rate to FP32, favors the RTX 4080 SUPER by an order of magnitude or more. The RTX 4080 SUPER's average benchmark score of 54,209 places it near the top of the database, within 1% of its nearest rival, the RTX 4080, which scores 54,247. The RTX 4080 SUPER is also within 1.1% of the AMD Radeon Pro W5700X at 54,828 and within 2.7% of the AMD Radeon RX 6750 GRE 12 GB at 55,698.

The Ryzen Z2 A GPU, with no benchmark scores recorded, cannot be positioned against those figures. Its 50th percentile standing among all GPUs suggests mid-pack placement, but without scores, any quantitative comparison is impossible. The RTX 4080 SUPER's 86th percentile confirms its high-end status. For users who need maximum frame rates, ray tracing performance, or compute throughput, the RTX 4080 SUPER is the only choice from this pair. For users building low-power, compact systems where a 15 W part suffices, the Ryzen Z2 A GPU delivers 16 GB of memory and RDNA 2.0 features without the thermal and power demands of the RTX 4080 SUPER. The RTX 4080 SUPER is marked end-of-life in the database, while the Ryzen Z2 A GPU remains active in production.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark results between these two GPUs. However, the RTX 4080 SUPER has ten recorded benchmark scores across multiple test suites. Its 3DMark Steel Nomad DX12 score is 6,600. In Geekbench, it scores 219,065 in OpenCL and 260,075 in Vulkan. PassMark results include 193 in DirectX 10, 301 in DirectX 11, 134 in DirectX 12, 381 in DirectX 9, 1,270 in G2D, 34,245 in G3D, and 19,822 in GPU compute. The average of all these benchmarks is 54,209.

The Ryzen Z2 A GPU has no benchmark scores recorded, so direct numerical comparison is not possible. What the data does show is the scale of the architectural gap. The RTX 4080 SUPER's pixel rate of 285.6 GPixel/s is 11 times the Ryzen Z2 A GPU's 25.60 GPixel/s. The texture rate difference is even larger: 816.0 GTexel/s versus 51.20 GTexel/s, a 16 times margin. Memory bandwidth of 736.3 GB/s versus 102.4 GB/s gives the RTX 4080 SUPER about seven times more data throughput. The shading unit count of 10,240 versus 512 is a 20 times difference. These ratios consistently point to the RTX 4080 SUPER being a high-end desktop part and the Ryzen Z2 A GPU being a low-power integrated-style solution.

The RTX 4080 SUPER's nearest rival, the RTX 4080, scores 54,247, which is just 38 points higher than the 4080 SUPER's 54,209. That 0.1% delta means the two are effectively tied in aggregate performance. The other rivals sit slightly above: the AMD Radeon Pro W5700X at 54,828 is 1.1% higher, the AMD Radeon RX 6750 GRE 12 GB at 55,698 is 2.7% higher, and the AMD Radeon 8060S at 55,757 is 2.8% higher. These margins are small enough that real-world differences would depend on specific workloads and driver optimizations.
