Architecture Differences

The AMD Ryzen Z2 A GPU is built on the Van Gogh chip with RDNA 2.0 architecture. It uses a 7 nm process from TSMC and integrates 2,400 million transistors on a 163 mm² die, giving a transistor density of 14.7 million per square millimeter. The chip is classified as a Console GPU generation part and is produced by AMD.

The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip with Blackwell 2.0 architecture. It is fabricated on a 5 nm TSMC process and packs 45,600 million transistors on a 378 mm² die, which works out to 120.6 million transistors per square millimeter. The part belongs to the GeForce 50-series generation.

The compute resources differ by a wide margin. The AMD chip has 512 shading units, 32 texture mapping units, and 16 raster operations units, plus 8 ray tracing cores. The NVIDIA chip carries 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The NVIDIA part also has a much larger complement of fixed-function hardware relative to the AMD design.

Clock behavior also separates the two. The AMD GPU runs at a 1000 MHz base clock and a 1600 MHz boost clock, with memory at 800 MHz or 6.4 Gbps effective. The NVIDIA GPU runs at a 2295 MHz base clock and a 2617 MHz boost clock, with memory at 2000 MHz or 32 Gbps effective. The NVIDIA part maintains higher clocks despite having far more compute units.

Memory architecture is another major split. The AMD part uses 16 GB of LPDDR5 across a 128 bit bus, delivering 102.4 GB/s. The NVIDIA part uses 24 GB of GDDR7 across a 256 bit bus, delivering 1.02 TB/s. The NVIDIA memory bus is twice as wide and the memory type is significantly faster.

The physical and power profile is starkly different. The AMD chip is rated at 15 W, has a single USB Type-C display output, and no listed slot width, power connectors, bus interface, or dimensions. The NVIDIA chip is rated at 415 W, uses a dual-slot cooler with a single 16-pin power connector, connects via PCIe 5.0 x16, and measures 304 mm by 137 mm by 40 mm. The display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Release timing also differs. The AMD Ryzen Z2 A GPU carries a release date of 2024-12-31, while the NVIDIA GeForce RTX 5080 SUPER carries a release date of 2025-12-31. Both are listed as Active in production status.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen Z2 A GPU and the NVIDIA GeForce RTX 5080 SUPER. The wins are recorded as 0 for each side, and the head-to-head benchmark array is empty.

However, the available data allows for a comparison of compute throughput. The NVIDIA part delivers 56.28 TFLOPS of FP32 performance, while the AMD part delivers 1.638 TFLOPS. That places the NVIDIA chip roughly 34 times higher in raw single-precision throughput. For FP16, the NVIDIA chip also delivers 56.28 TFLOPS at a 1:1 ratio, while the AMD chip delivers 3.277 TFLOPS at a 2:1 ratio. The NVIDIA part is about 17 times higher in FP16 throughput.

Texture and pixel rates follow the same pattern. The NVIDIA GPU reaches 879.3 GTexel/s and 293.1 GPixel/s. The AMD GPU reaches 51.20 GTexel/s and 25.60 GPixel/s. The NVIDIA part is roughly 17 times faster in texturing and about 11 times faster in pixel fill.

The only recorded benchmark score belongs to the NVIDIA part. It scores 3075 in 3DMark Steel Nomad DX12, placing it in the 19th percentile among all GPUs in the database. The AMD part has no benchmark entries and sits at the 50th percentile by default with an average benchmark score of 0. Because the AMD part has no measured score, no direct percentage comparison can be made between the two in any recorded workload.

The nearest rivals for the NVIDIA part provide context for its measured result. The NVIDIA Quadro P1000 averages 3163, which is 2.8% higher. The Intel Arc Pro B60 averages 3182, which is 3.4% higher. The NVIDIA GeForce 820A averages 2983, which is 3.1% lower. The NVIDIA GeForce GTX 860M averages 2967, which is 3.6% lower. These are narrow margins, indicating the RTX 5080 SUPER sits in a tight cluster around the 3000 score mark in this specific benchmark.

The Verdict

The recorded data shows an extreme imbalance between these two parts. The NVIDIA GeForce RTX 5080 SUPER has a measured 3DMark Steel Nomad DX12 score of 3075, while the AMD Ryzen Z2 A GPU has no benchmark score in the database. The NVIDIA chip also leads decisively in FP32 throughput, FP16 throughput, texture rate, pixel rate, memory bandwidth, and memory capacity.

The AMD Ryzen Z2 A GPU is a 15 W console-class processor with 16 GB of LPDDR5 memory and 1.638 TFLOPS of FP32 compute. Its strengths are low power draw, a compact unlisted physical footprint, and a single USB Type-C output. The NVIDIA part is a 415 W desktop GPU with 24 GB of GDDR7, 56.28 TFLOPS of FP32 compute, and a dual-slot cooler requiring a 16-pin power connector.

For workloads that depend on raw graphics throughput, the data points entirely toward the NVIDIA part. For workloads that depend on low power consumption and minimal cooling requirements, the AMD part is the only one of the two that fits that profile. The choice depends on whether the use case prioritizes compute and memory throughput or power efficiency. There is no benchmark overlap in the database, so any direct performance comparison beyond the recorded specs is not supported by the data.

Where Each One Wins

The NVIDIA GeForce RTX 5080 SUPER wins in every measured performance category where a numeric comparison is possible. Its FP32 throughput of 56.28 TFLOPS dwarfs the AMD part's 1.638 TFLOPS. Its FP16 throughput of 56.28 TFLOPS dwarfs the AMD part's 3.277 TFLOPS. Its texture rate of 879.3 GTexel/s dwarfs the AMD part's 51.20 GTexel/s. Its pixel rate of 293.1 GPixel/s dwarfs the AMD part's 25.60 GPixel/s. Its memory bandwidth of 1.02 TB/s is exactly ten times the AMD part's 102.4 GB/s. It also holds a 24 GB versus 16 GB memory capacity advantage and an 84 versus 8 RT core advantage.

The AMD Ryzen Z2 A GPU wins in power efficiency and physical footprint. Its 15 W TDP is dramatically lower than the NVIDIA part's 415 W. It requires no external power connector, no dual-slot cooler, and no PCIe slot, based on the missing fields in the database. Its single USB Type-C output suggests a minimal display configuration. The NVIDIA part, by contrast, needs a 16-pin power connector, a dual-slot cooler, and a PCIe 5.0 x16 interface, and it measures 304 mm in length.

For scenarios where the workload is compute-heavy, memory-heavy, or ray-traced, the NVIDIA part is the clear choice based on the recorded specifications. For scenarios where power draw is the limiting factor and the system must operate at 15 W, the AMD part is the only viable option in this comparison. The NVIDIA part also has a recorded benchmark score, so it can be placed relative to other GPUs in the database. The AMD part cannot be placed relative to any GPU because it has no recorded benchmark score.

The release dates also matter. The AMD part launched in 2024, while the NVIDIA part launched in 2025. The NVIDIA part carries a launch MSRP of 999 USD. The AMD part has no launch MSRP in the database. Both parts are listed as Active in production status, so neither is discontinued.
