AMD Radeon RX 9070 GRE vs AMD Ryzen Z2 A GPU Comparison

The Verdict

The recorded data positions the AMD Radeon RX 9070 GRE as a discrete desktop graphics card with a benchmark percentile of 87, while the AMD Ryzen Z2 A GPU sits at the 50th percentile. The RX 9070 GRE delivers a substantial performance advantage based on architectural resources: it carries 3,072 shading units, 192 texture mapping units, and 96 render output units, compared to 512 shading units, 32 TMUs, and 16 ROPs for the Z2 A GPU. The RX 9070 GRE also reaches 34.28 TFLOPS of FP32 compute, while the Z2 A GPU delivers 1.638 TFLOPS. The average benchmark score for the RX 9070 GRE is 57,367, whereas the Z2 A GPU has no recorded benchmark entries and an average score of zero.

The RX 9070 GRE is the clear choice for desktop gaming and high-resolution rendering, given its 12 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s bandwidth. The Z2 A GPU, with 16 GB of LPDDR5 on a 128-bit bus and 102.4 GB/s bandwidth, offers more capacity but far lower throughput. For users prioritizing compute throughput, texture fill, and pixel fill, the RX 9070 GRE is the only viable option from this data. The Z2 A GPU, meanwhile, appears tailored for low-power or embedded scenarios, given its 15 W TDP versus 220 W for the RX 9070 GRE. The data does not support any scenario where the Z2 A GPU outperforms the RX 9070 GRE; the difference in FP32 throughput alone is roughly 21 times in favor of the RX 9070 GRE.

Architecture Differences

The two GPUs come from different RDNA generations. The RX 9070 GRE uses the Navi 48 chip with RDNA 4.0 architecture, built on TSMC's 4 nm process. The Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. This node difference is significant: the RX 9070 GRE packs 53,900 million transistors into a 357 mm² die, yielding a transistor density of 151.0 million per square millimeter. The Z2 A GPU contains only 2,400 million transistors on a 163 mm² die, for a density of 14.7 million per square millimeter. That represents a roughly tenfold difference in transistor density, which explains the massive compute gap between the two parts.

The RX 9070 GRE features 48 ray tracing cores, while the Z2 A GPU has 8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RX 9070 GRE is part of the Navi IV (RX 9000) generation, with a predecessor of Navi III, while the Z2 A GPU is classified as a Console GPU (AMD) generation with no predecessor or successor listed. The RX 9070 GRE has a boost clock of 2790 MHz and a game clock of 2220 MHz, compared to the Z2 A GPU's 1600 MHz boost and 1000 MHz base. Memory clocks also differ sharply: the RX 9070 GRE runs at 2250 MHz with 18 Gbps effective, while the Z2 A GPU runs at 800 MHz with 6.4 Gbps effective.

The RX 9070 GRE uses a PCIe 5.0 x16 bus interface and dual 8-pin power connectors with a suggested 550 W power supply. The Z2 A GPU has no recorded bus interface, power connector, or suggested PSU data. Display outputs differ as well: the RX 9070 GRE provides 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the Z2 A GPU provides only 1x USB Type-C. The RX 9070 GRE is a dual-slot card, while slot width for the Z2 A GPU is not recorded. The RX 9070 GRE was released on 2025-05-07 and has a launch MSRP of 549 USD, while the Z2 A GPU was released on 2024-12-31 with no launch MSRP recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. However, the individual benchmark results for the RX 9070 GRE provide a reference point. In 3DMark Steel Nomad DX12, the RX 9070 GRE scores 5,424. In Geekbench OpenCL, it scores 109,309. The Z2 A GPU has no recorded benchmark scores at all, so direct numerical comparison is limited to the specification-level data.

The nearest rivals for the RX 9070 GRE, based on average benchmark score, include the Intel Arc A580 at 57,756 with a delta of -0.7%, the AMD Radeon RX 5600 OEM at 58,085 with a delta of -1.2%, the Intel Arc A570M at 58,239 with a delta of -1.5%, and the AMD Radeon RX 6950 XT at 58,392 with a delta of -1.8%. These deltas are all negative, meaning the RX 9070 GRE's average score of 57,367 is slightly below each of these rivals. The closest competitor is the Intel Arc A580, which trails by only 0.7%.

The Z2 A GPU has no nearest rivals recorded, which limits comparative analysis. The absence of benchmark data for the Z2 A GPU means the only measurable comparison is through architectural specifications. The RX 9070 GRE's FP32 throughput of 34.28 TFLOPS versus the Z2 A GPU's 1.638 TFLOPS is the most decisive single metric, followed by texture rate (535.7 GTexel/s versus 51.20 GTexel/s) and pixel rate (267.8 GPixel/s versus 25.60 GPixel/s). These differences align with the RX 9070 GRE's 87th percentile ranking versus the Z2 A GPU's 50th percentile.

Where Each One Wins

The RX 9070 GRE wins decisively in every measurable performance category. Its 34.28 TFLOPS FP32 compute makes it suitable for demanding rendering workloads, while its 535.7 GTexel/s texture rate and 267.8 GPixel/s pixel rate support high-resolution texture mapping and rasterization. The 432.0 GB/s memory bandwidth on a 192-bit bus provides ample data throughput for large textures and frame buffers. With 48 ray tracing cores, the RX 9070 GRE is positioned for hardware-accelerated ray tracing workloads. Its 12 GB GDDR6 memory, while smaller than the Z2 A GPU's 16 GB, offers much faster memory technology and bandwidth.

The Z2 A GPU wins in power efficiency and memory capacity. At 15 W TDP, it consumes a fraction of the RX 9070 GRE's 220 W. Its 16 GB LPDDR5 memory provides more capacity, which could benefit workloads requiring large datasets that fit within a slower memory pool. The 102.4 GB/s bandwidth, however, is a limiting factor. The Z2 A GPU's 3.277 TFLOPS FP16 throughput with a 2:1 ratio indicates some mixed-precision capability, though the RX 9070 GRE's FP16 performance of 34.28 TFLOPS with a 1:1 ratio is far higher in absolute terms.

The RX 9070 GRE also wins in connectivity and interface options, offering PCIe 5.0 x16, HDMI 2.1b, and three DisplayPort 2.1a outputs. The Z2 A GPU has a single USB Type-C output and no recorded bus interface. For desktop expansion and multi-monitor setups, the RX 9070 GRE is the only option with recorded support. The Z2 A GPU's lack of power connector data and suggested PSU requirements suggests it may be designed for integrated or mobile scenarios, though the database does not explicitly confirm this. The RX 9070 GRE's dual-slot form factor and dual 8-pin connectors indicate a traditional add-in card design, while the Z2 A GPU's compact footprint aligns with lower-power applications.
