AMD Ryzen Z2 Go GPU vs NVIDIA H800 SXM5 Comparison

AMD Ryzen Z2 Go GPU and NVIDIA H800 SXM5 occupy opposite ends of the hardware spectrum. The database records no direct benchmark matchups, so the analysis relies on the recorded architectural and specification differences. Both products hold a 50th percentile position among all GPUs in the database, yet their physical and performance profiles diverge sharply.

The AMD Ryzen Z2 Go GPU is a compact, low-power graphics solution built on the Rembrandt+ chip. It uses the RDNA 2.0 architecture, manufactured on a 6 nm process at TSMC. The chip contains 13,100 million transistors on a 208 mm² die, giving a transistor density of 63.0 million per square millimeter. The NVIDIA H800 SXM5, by contrast, uses the GH100 chip with the Hopper architecture. It is built on a 5 nm process, also at TSMC, with 80,000 million transistors spread across an 814 mm² die. The transistor density reaches 98.3 million per square millimeter. The H800 SXM5 is a server-class module, while the Z2 Go is a console GPU generation product.

Where Each One Wins

The recorded data shows no head-to-head benchmark wins for either product. The winsA and winsB fields both read zero, and the headToHeadBenchmarks array is empty. This absence of direct comparisons means the allocation of strengths must come from the specification sheets.

The AMD Ryzen Z2 Go GPU wins in power efficiency and physical integration. Its thermal design power is 28 W, a figure that compares favorably to the H800 SXM5's 700 W. The Z2 Go requires no power connectors, while the H800 SXM5 uses an 8-pin EPS connector. The Z2 Go also offers a display output, a single USB Type-C port, whereas the H800 SXM5 has no display outputs at all. For systems needing graphics output and low power draw, the Z2 Go is the only viable option based on the data.

The NVIDIA H800 SXM5 wins decisively in raw compute capacity. Its FP32 throughput is 59.30 TFLOPS, its FP16 throughput is 237.2 TFLOPS, and its texture rate is 926.6 GTexel/s. The Z2 Go delivers 4.147 TFLOPS FP32, 8.294 TFLOPS FP16, and 129.6 GTexel/s. Memory bandwidth also favors the H800 SXM5 overwhelmingly: 3.36 TB/s versus 102.4 GB/s. The H800 SXM5 has 80 GB of HBM3 memory on a 5120-bit bus, while the Z2 Go has 16 GB of LPDDR5 on a 128-bit bus.

The pixel rate tells a different story. The Z2 Go achieves 86.40 GPixel/s, while the H800 SXM5 achieves 42.12 GPixel/s. For pure pixel fill, the smaller AMD part leads. This suggests the Z2 Go is tuned for rasterization workloads where pixel output matters, whereas the H800 SXM5 prioritizes compute and texture throughput.

The Verdict

Based strictly on the recorded data, the choice between these two products depends entirely on the workload context. The AMD Ryzen Z2 Go GPU suits applications requiring low power consumption, a display output, and compact integration. Its 28 W TDP, lack of external power connectors, and USB Type-C output make it a self-contained graphics solution for portable or embedded systems. The 16 GB LPDDR5 memory and 102.4 GB/s bandwidth provide adequate capacity for standard graphics tasks, and the 12 ray tracing cores add hardware acceleration for ray-traced effects.

The NVIDIA H800 SXM5 is a server compute module. It has no display outputs, draws 700 W, and requires an 8-pin EPS power connector plus a 1100 W suggested PSU. Its 80 GB HBM3 memory with 3.36 TB/s bandwidth and 528 tensor cores point to large-scale data processing, machine learning inference, and high-throughput scientific computing. The FP16 performance of 237.2 TFLOPS shows a 4:1 ratio to FP32, indicating optimized mixed-precision workloads. The Z2 Go's FP16 ratio is 2:1, capping at 8.294 TFLOPS.

The verdict from the data: pick the Z2 Go for graphics output and low-power operation. Pick the H800 SXM5 for compute density and memory bandwidth. There is no middle ground in the recorded specifications. The H800 SXM5 is not a graphics card in the traditional sense, given its absence of display outputs, and the Z2 Go is not a compute accelerator at the scale of the H800 SXM5.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between these two GPUs. The headToHeadBenchmarks array is empty, and both winsA and winsB are zero. Consequently, there are no exact numbers to compare in direct testing. The analysis must instead rely on the specification-derived metrics.

The largest compute gap appears in FP32 throughput. The H800 SXM5 delivers 59.30 TFLOPS, which is approximately 14.3 times the Z2 Go's 4.147 TFLOPS. This ratio comes directly from the recorded figures. In FP16, the H800 SXM5's 237.2 TFLOPS is roughly 28.6 times the Z2 Go's 8.294 TFLOPS. The tensor core count of 528 on the H800 SXM5 further separates the two, as the Z2 Go lists no tensor cores.

Memory bandwidth presents an even starker contrast. The H800 SXM5's 3.36 TB/s is about 33.6 times the Z2 Go's 102.4 GB/s. The bus width differential is 5120 bits versus 128 bits, a 40-fold difference. Memory size differs by a factor of five: 80 GB versus 16 GB.

Texture rate favors the H800 SXM5 at 926.6 GTexel/s against 129.6 GTexel/s, a 7.15 times advantage. The shading unit count is 16,896 on the H800 SXM5 versus 768 on the Z2 Go, a 22 times difference. TMUs are 528 versus 48, an 11 times difference.

The pixel rate is the only metric where the Z2 Go leads. Its 86.40 GPixel/s exceeds the H800 SXM5's 42.12 GPixel/s by roughly 2.05 times. This outcome stems from the ROP configuration: the Z2 Go has 32 ROPs, while the H800 SXM5 has only 24, combined with the Z2 Go's higher boost clock of 2700 MHz versus 1755 MHz.
