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

AMD Radeon RX 9070 GRE and AMD Ryzen Z2 Go GPU occupy entirely different segments of the graphics hardware spectrum. The RX 9070 GRE is a full-size desktop add-in board from the Radeon RX 9000 series, built on the Navi 48 chip with RDNA 4.0 architecture, while the Ryzen Z2 Go GPU is a console-class integrated graphics solution using the Rembrandt+ chip with RDNA 2.0 architecture. The recorded data shows a decisive performance gap, yet each part serves a purpose dictated by its physical design, power envelope, and memory subsystem. This analysis compares the two strictly on benchmark data, architectural specifications, and recorded feature sets.

Where Each One Wins

The AMD Radeon RX 9070 GRE wins in every measurable performance category. Its benchmark results are substantial: a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. The Ryzen Z2 Go GPU has no recorded benchmark entries in the database, meaning its average benchmark score is 0 and its percentile ranking sits at 50, compared to the RX 9070 GRE's 87th percentile among all GPUs. The desktop card delivers 34.28 TFLOPS of FP32 compute, while the Z2 Go GPU manages 4.147 TFLOPS, an 8.3x difference in raw floating-point throughput. In memory bandwidth, the RX 9070 GRE provides 432.0 GB/s over a 192-bit bus, versus the Z2 Go GPU's 102.4 GB/s over a 128-bit interface.

Where the Ryzen Z2 Go GPU wins is strictly in efficiency and form factor. Its 28 W TDP is a fraction of the RX 9070 GRE's 220 W TDP, and it requires no power connectors, relying on a 1x USB Type-C display output. The Z2 Go GPU also has more memory capacity at 16 GB, though it is LPDDR5 rather than GDDR6. The desktop card uses dual 8-pin power connectors and a dual-slot cooler, making it unsuitable for compact or mobile designs. The Z2 Go GPU's RDNA 2.0 architecture with a base clock of 800 MHz and boost of 2700 MHz targets low-power embedded or handheld scenarios, whereas the RX 9070 GRE's 1420 MHz base and 2790 MHz boost clocks assume a robust desktop power delivery system.

Architecture Differences

The architectural divide between the two parts is generational and physical. The RX 9070 GRE uses the Navi 48 chip fabricated on a 4 nm process at TSMC, with 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0M per mm². The Ryzen Z2 Go GPU uses the Rembrandt+ chip on a 6 nm process, also at TSMC, with 13,100 million transistors on a 208 mm² die, giving a density of 63.0M per mm². This process and density difference directly explains the compute gap: the RX 9070 GRE has 3072 shading units, 192 texture mapping units, and 96 ROPs, while the Z2 Go GPU has 768 shading units, 48 TMUs, and 32 ROPs.

Ray tracing hardware also differs. The RX 9070 GRE includes 48 RT cores, whereas the Z2 Go GPU has 12 RT cores. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. FP16 processing differs in ratio: the RX 9070 GRE delivers 34.28 TFLOPS of FP16 at a 1:1 ratio with FP32, while the Z2 Go GPU delivers 8.294 TFLOPS of FP16 at a 2:1 ratio. This means the desktop card processes FP16 at the same rate as FP32, whereas the Z2 Go GPU halves its FP16 rate relative to FP32, indicating a more limited shader design.

Memory technology is another core distinction. The RX 9070 GRE uses 12 GB of GDDR6 on a 192-bit bus with a memory clock of 2250 MHz (18 Gbps effective). The Z2 Go GPU uses 16 GB of LPDDR5 on a 128-bit bus with a memory clock of 800 MHz (6.4 Gbps effective). The desktop card's bandwidth advantage is 4.2x, which is critical for texture-heavy workloads. The Z2 Go GPU's larger capacity suggests it is intended for unified memory architectures in embedded systems, where the CPU and GPU share the same memory pool.

Head-to-Head Benchmarks

Direct head-to-head benchmark results are not recorded in the database, so the comparison relies on the individual benchmark scores and average figures. The RX 9070 GRE's 3DMark Steel Nomad DX12 score of 5424 represents a modern rasterization workload. Its Geekbench OpenCL score of 109309 reflects general-purpose compute. The Z2 Go GPU has no scores for either test, meaning its performance cannot be quantified in these specific workloads. The average benchmark score for the RX 9070 GRE is 57367, while the Z2 Go GPU sits at 0, a direct consequence of missing entries.

The nearest rivals for the RX 9070 GRE provide context. Intel Arc A580 scores 57756, which is 0.7% higher than the RX 9070 GRE's average. AMD Radeon RX 5600 OEM scores 58085, 1.2% higher. Intel Arc A570M scores 58239, 1.5% higher. AMD Radeon RX 6950 XT scores 58392, 1.8% higher. These deltas show the RX 9070 GRE sits in a tight cluster of mid-range to upper-mid-range GPUs, within 2% of each rival. The Z2 Go GPU has no nearest rivals listed, reinforcing its status as a low-power part with no direct desktop competition in the database.

In terms of pixel and texture rates, the RX 9070 GRE achieves 267.8 GPixel/s and 535.7 GTexel/s. The Z2 Go GPU achieves 86.40 GPixel/s and 129.6 GTexel/s. The desktop card is 3.1x faster in pixel fill and 4.1x faster in texture fill. These ratios align with the FP32 compute difference and confirm that the RX 9070 GRE is designed for high-resolution rendering and texture-heavy scenes, while the Z2 Go GPU is limited to lower resolutions and simpler geometry.

The Verdict

The data points to a clear split by use case. The AMD Radeon RX 9070 GRE is the only choice for desktop gaming or compute workloads where performance matters. Its 3DMark Steel Nomad score of 5424, OpenCL score of 109309, and 87th percentile ranking place it in a competitive position among desktop GPUs, within 2% of rivals like the Intel Arc A580 and AMD Radeon RX 6950 XT. Its 34.28 TFLOPS FP32 compute, 432.0 GB/s memory bandwidth, and 48 RT cores make it suitable for high-refresh-rate gaming, ray-traced titles, and CUDA-style compute tasks. The 220 W TDP and dual 8-pin connectors assume a desktop power supply of at least 550 W, which is standard for this performance class.

The AMD Ryzen Z2 Go GPU is a low-power integrated solution for compact systems. Its 28 W TDP, no external power requirement, and USB Type-C output indicate a design for handhelds or embedded boards. Its 16 GB LPDDR5 memory provides capacity for unified memory workloads, but the 102.4 GB/s bandwidth and 4.147 TFLOPS FP32 performance limit it to light gaming or media tasks. The 50th percentile ranking is a baseline position with no benchmark data to support higher claims. The RX 9070 GRE outperforms the Z2 Go GPU by an order of magnitude in compute, fill rates, and memory bandwidth, so the selection depends entirely on whether the target platform can accommodate a dual-slot, 220 W desktop card or requires a 28 W embedded part. The RX 9070 GRE is the performance leader without qualification; the Z2 Go GPU is the efficiency leader without competition in its power class.
