AMD Radeon RX 9070 vs AMD Ryzen Z2 GPU Comparison

AMD Radeon RX 9070 and AMD Ryzen Z2 GPU occupy opposite ends of the graphics spectrum, despite sharing a manufacturer and process node. The RX 9070 is a discrete desktop card from the Radeon RX 9000 series, built on the Navi 48 chip with RDNA 4.0 architecture. The Ryzen Z2 GPU is a console-class integrated processor, using the Hawk Point chip with RDNA 3.0 architecture. Both are fabricated on TSMC’s 4 nm process, but the similarity ends there. The database records no direct head-to-head benchmark results between these two, and the Ryzen Z2 GPU has no individual benchmark entries or rival comparisons. The RX 9070, by contrast, has a full suite of recorded scores across multiple test suites, an average benchmark score of 23877, and a percentile rank of 69 among all GPUs. The Ryzen Z2 GPU sits at the 50th percentile with an average score of zero due to missing data. This analysis relies entirely on recorded specifications and the RX 9070’s measured performance, interpreting what the data indicates about each product’s intended role and capability.

Where Each One Wins

The RX 9070 wins in every measured performance category. Its shading unit count is 4.67 times higher, its TMU count is 4.67 times higher, and its ROP count is 4 times higher. Compute throughput is 4.36 times higher in FP32, and memory bandwidth is 5.38 times higher. The RX 9070 also leads in feature support with 56 ray tracing cores versus 12. The Ryzen Z2 GPU’s only recorded wins are a higher boost clock (2700 MHz versus 2520 MHz) and a lower TDP (28 W versus 220 W). For any workload involving rasterization, texturing, ray tracing, or memory-intensive tasks, the RX 9070 is the clear choice. The Ryzen Z2 GPU is suited for power-constrained environments, likely integrated into a console or handheld system, where its 28 W envelope and lack of external power connectors are advantages. The RX 9070, with its dual-slot cooler and 2x 8-pin connectors, is designed for desktop expansion slots and high-end gaming.

Architecture Differences

The RX 9070 uses the Navi 48 chip with RDNA 4.0 architecture, part of the Navi IV generation for the RX 9000 series. The Ryzen Z2 GPU uses the Hawk Point chip with RDNA 3.0 architecture, classified as a console GPU. Both are built on TSMC’s 4 nm process, but the RX 9070 packs 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0M per mm². The Ryzen Z2 GPU contains 25,390 million transistors on a 178 mm² die, with a density of 142.6M per mm². The RX 9070’s transistor count is more than double that of the Ryzen Z2 GPU. The architecture generation difference (RDNA 4.0 versus RDNA 3.0) suggests the RX 9070 benefits from newer design refinements, though the database does not list specific architectural feature changes. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RX 9070’s display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the Ryzen Z2 GPU has a single USB Type-C output, indicating its integrated nature.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the RX 9070 and the Ryzen Z2 GPU, and the Ryzen Z2 GPU has zero recorded benchmark scores. The RX 9070, however, has ten individual benchmark entries. In 3DMark Steel Nomad DX12, it scores 6290. Geekbench OpenCL returns 131539, and Geekbench Vulkan returns 58705. Passmark scores include 141 for DirectX 10, 281 for DirectX 11, 74 for DirectX 12, 343 for DirectX 9, 1280 for G2D, 25381 for G3D, and 14737 for GPU Compute. Its average benchmark score is 23877, placing it at the 69th percentile among all GPUs. The nearest rivals in the database provide context: the RX 9070 is 0.6% ahead of the NVIDIA GeForce GTX TITAN Z (which scores 23736), 1.1% ahead of the NVIDIA GeForce RTX 3080 Mobile (23628), 0.8% behind the AMD Radeon RX 6800S (24063), and 1.2% behind the NVIDIA GeForce RTX 2080 SUPER (24170). These deltas are small, indicating the RX 9070 sits in a tight performance band near the top of the mid-range desktop segment. Without any recorded scores for the Ryzen Z2 GPU, no direct numerical comparison is possible. The specification data, however, shows a 4.36x gap in FP32 compute and a 5.38x gap in memory bandwidth in favor of the RX 9070.

The Verdict

The RX 9070 is a discrete desktop GPU designed for high-performance gaming and compute workloads. Its recorded benchmark scores confirm it operates near the level of the NVIDIA GeForce RTX 2080 SUPER and slightly above the GTX TITAN Z, with an average score of 23877. The Ryzen Z2 GPU, with a 28 W TDP and no benchmark data, is an integrated solution for power-sensitive devices. The data shows the RX 9070 is the choice for anyone building a desktop system with room for a dual-slot card, a 550 W PSU, and PCIe 5.0 connectivity. Its 16 GB of GDDR6 memory and 644.6 GB/s bandwidth support high-resolution textures and memory-heavy workloads. The Ryzen Z2 GPU, with 16 GB of LPDDR5X and 119.9 GB/s bandwidth, suits compact, low-power systems where the 28 W envelope is critical. The RX 9070’s 56 ray tracing cores versus 12 on the Ryzen Z2 GPU indicates a substantial advantage in ray-traced scenes. The Ryzen Z2 GPU’s higher boost clock (2700 MHz) does not compensate for its lower shader count and memory bandwidth. For any performance-oriented use case, the RX 9070 is the only option with recorded evidence of capability. The Ryzen Z2 GPU’s lack of benchmark results means its real-world performance is unverified in the database. Users seeking a drop-in desktop card with measurable results should select the RX 9070. Users constrained by power and space, such as in a portable console, have no data to evaluate the Ryzen Z2 GPU beyond its specifications.
