AMD Ryzen Z2 Go GPU vs NVIDIA GeForce RTX 5080 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Ryzen Z2 Go GPU versus the NVIDIA GeForce RTX 5080. The recorded data for the AMD Ryzen Z2 Go GPU includes no benchmark scores, no average score, and no nearest rival entries. The NVIDIA GeForce RTX 5080, by contrast, has a full set of ten benchmark scores and a computed average benchmark score of 56083.

The NVIDIA GeForce RTX 5080 delivers an average benchmark score of 56083, placing it in the 87th percentile among all GPUs in the database. Its nearest rivals, all AMD products, are tightly clustered: the AMD Radeon 8060S scores 55757 (0.6% behind), the AMD Radeon RX 6750 GRE 12 GB scores 55698 (0.7% behind), and the AMD Radeon Pro W5700X scores 54828 (2.3% behind). The only rival ahead is the AMD Radeon RX 9070 GRE at 57367, which leads by 2.2%.

For the AMD Ryzen Z2 Go GPU, the database shows a percentile rank of 50 among all GPUs, but no measured scores exist to quantify its performance relative to the RTX 5080. The RTX 5080’s individual benchmark results span several suites. In 3DMark Steel Nomad (DX12), it scores 8637. In Geekbench, it records 235901 for OpenCL and 255450 for Vulkan. The PassMark suite shows 36565 for G3D, 21789 for GPU compute, 1415 for G2D, 389 for DirectX 9, 324 for DirectX 11, 208 for DirectX 10, and 151 for DirectX 12.

Because the Ryzen Z2 Go GPU has no benchmark entries, the head-to-head comparison is one-sided. The RTX 5080’s average score of 56083 stands as the sole quantitative reference point, while the Z2 Go’s percentile of 50 indicates a mid-pack standing in the overall GPU distribution, though without a measured score, this percentile cannot be tied to any specific performance level in the recorded data.

Where Each One Wins

The NVIDIA GeForce RTX 5080 wins in every category where recorded data exists. Its compute performance, as measured by PassMark GPU compute at 21789, and its DirectX 11 score of 324, DirectX 12 score of 151, and DirectX 9 score of 389, provide a full performance envelope across legacy and modern APIs. The Geekbench Vulkan result of 255450 and OpenCL result of 235901 confirm strong cross-platform compute capabilities.

The AMD Ryzen Z2 Go GPU has no wins in the database because no benchmark scores are recorded for it. Its specification sheet suggests a different usage profile: a 28 W TDP, 6 nm process, and 16 GB of LPDDR5 memory with a 128-bit bus and 102.4 GB/s bandwidth. The RTX 5080, by contrast, draws 360 W, uses a 5 nm process, and pairs 16 GB of GDDR7 memory with a 256-bit bus and 960.0 GB/s bandwidth. The Z2 Go’s pixel rate is 86.40 GPixel/s and texture rate is 129.6 GTexel/s, while the RTX 5080 achieves 293.1 GPixel/s and 879.3 GTexel/s, respectively.

In floating-point performance, the RTX 5080 delivers 56.28 TFLOPS for both FP32 and FP16 (1:1 ratio), whereas the Z2 Go provides 4.147 TFLOPS FP32 and 8.294 TFLOPS FP16 (2:1 ratio). The RTX 5080’s shading unit count of 10752, texture mapping units of 336, and ROPs of 112 dwarf the Z2 Go’s 768 shaders, 48 TMUs, and 32 ROPs. The RTX 5080 also includes 84 RT cores and 336 tensor cores, while the Z2 Go lists 12 RT cores and no tensor cores.

The usage split is clear from the data. The RTX 5080 is positioned for high-end desktop workloads with its dual-slot cooler, 1x 16-pin power connector, 750 W suggested PSU, and PCIe 5.0 x16 interface. The Z2 Go uses no power connectors, has a single USB Type-C display output, and draws only 28 W, indicating a low-power integrated-class solution. The RTX 5080’s launch MSRP is 999 USD, a figure stated once here as recorded in the database.

Architecture Differences

The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip with RDNA 2.0 architecture, categorized under Console GPU (AMD). The NVIDIA GeForce RTX 5080 uses the GB203 chip with Blackwell 2.0 architecture, part of the GeForce 50-series. The Z2 Go’s generation is listed as Console GPU (AMD), while the RTX 5080 belongs to GeForce 50. The Z2 Go’s release date is December 31, 2024; the RTX 5080’s is January 29, 2025. The RTX 5080 has a predecessor (GeForce 40) and successor (GeForce 60); the Z2 Go lists neither.

API support is identical for both: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 adds tensor cores (336) for AI-oriented workloads, a feature absent from the Z2 Go. The RT core count differs by a factor of 7 (12 versus 84), and the FP16 ratio differs: the Z2 Go halves its FP16 throughput relative to FP32 (2:1), while the RTX 5080 maintains a 1:1 ratio.

The Z2 Go’s memory clock of 800 MHz with 6.4 Gbps effective transfer and LPDDR5 indicates a unified memory design typical of low-power console-class parts. The RTX 5080’s 1875 MHz GDDR7 at 30 Gbps effective, combined with a 256-bit bus, yields 960.0 GB/s, a 9.4x bandwidth advantage. The Z2 Go’s process node is 6 nm versus 5 nm, and its transistor density is roughly half that of the RTX 5080, reflecting the different design targets: a 28 W integrated part versus a 360 W discrete flagship. The RTX 5080’s launch MSRP is 999 USD.
