AMD Radeon RX 7700 vs AMD Ryzen Z2 GPU Comparison

The Verdict

The data in this database separates these two AMD parts decisively. The AMD Radeon RX 7700 is a discrete desktop graphics card built for sustained, high-throughput rendering. The AMD Ryzen Z2 GPU is an integrated mobile processor graphics solution designed for power-constrained systems. The benchmark gap is not close. The RX 7700 produces an average benchmark score of 15852, while the Ryzen Z2 GPU has no recorded benchmark scores in the database. The RX 7700 sits in the 58th percentile of all GPUs tracked, whereas the Ryzen Z2 GPU sits in the 50th percentile with an average score of zero. The RX 7700 is the only one of the two with any measurable performance data.

The RX 7700 delivers 25.18 TFLOPS of FP32 compute, roughly three times the 8.294 TFLOPS of the Ryzen Z2 GPU. Its memory bandwidth is 624.1 GB/s versus 119.9 GB/s for the Z2. The RX 7700 uses a 256-bit bus with 16 GB of GDDR6 memory, while the Z2 uses a 128-bit bus with 16 GB of LPDDR5X. The RX 7700 has 2560 shading units, 160 texture mapping units, and 96 ROPs. The Z2 has 768 shading units, 48 TMUs, and 32 ROPs. In every compute-related specification recorded, the RX 7700 is ahead.

The Ryzen Z2 GPU does have advantages in power and physical size. Its TDP is 28 W, compared to 200 W for the RX 7700. The Z2 requires no external power connectors, while the RX 7700 needs two 8-pin connectors and a 550 W suggested power supply. The Z2 has no listed dimensions, while the RX 7700 measures 267 mm in length, 135 mm in height, and 50 mm in width. The Z2 is a compact integrated solution; the RX 7700 is a dual-slot expansion card. For a system that must run off minimal power and minimal space, the Z2 is the only realistic choice. For any system that can supply 200 W and accommodate a dual-slot card, the RX 7700 is overwhelmingly faster.

Where Each One Wins

The RX 7700 wins in every benchmark category that has recorded data. In the database, it scores 106028 in Geekbench OpenCL, 20974 in Passmark G3D, and 10963 in Passmark GPU Compute. It also records 2865 in 3DMark Steel Nomad DX12. These are the only benchmark results available between the two parts, and all of them belong to the RX 7700.

The Ryzen Z2 GPU has no wins in any benchmark, because it has no recorded benchmark scores. Its strengths are architectural and operational, not performance-based. It operates at a 28 W TDP and uses a 4 nm process node. The RX 7700 uses a 5 nm node and draws 200 W. The Z2 has a higher boost clock of 2700 MHz compared to the RX 7700's 2459 MHz, but the RX 7700 has a far higher base clock at 1900 MHz versus 800 MHz for the Z2. The Z2's higher boost clock does not translate into competitive throughput because it has far fewer execution units.

The Z2 also wins on transistor density. Its 142.6M transistors per square millimeter is significantly higher than the RX 7700's 81.2M per square millimeter. The Z2 packs 25,390 million transistors into a 178 mm² die, while the RX 7700 uses 28,100 million transistors across a 346 mm² die. This density advantage reflects the Z2's more modern 4 nm process, but it does not overcome the RX 7700's larger allocation of silicon to graphics compute.

For use cases, the RX 7700 is the part for desktop gaming, content creation, or any workload that demands high frame rates and high resolution rendering. The Z2 is the part for handheld consoles or ultra-compact systems where power draw is the primary constraint. The Z2 uses a single USB Type-C display output, while the RX 7700 provides 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The RX 7700 supports multi-display setups; the Z2 does not.

Architecture Differences

Both GPUs use the RDNA 3.0 architecture from AMD. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7700 belongs to the Radeon RX 7000 series, built on the Navi 32 chip with the codename Wheat Nas. The Ryzen Z2 GPU uses the Hawk Point chip and is classified as a Console GPU. The RX 7700 is part of the Navi III generation (RX 7000), with Navi II as its predecessor and Navi IV as its successor. The Z2 has no listed generation, predecessor, or successor.

The process nodes differ. The RX 7700 uses TSMC's 5 nm process. The Z2 uses TSMC's 4 nm process. The Z2's smaller node allows for higher transistor density: 142.6M per square millimeter versus 81.2M for the RX 7700. The Z2's die is 178 mm², less than half the RX 7700's 346 mm². Despite the smaller die, the Z2 packs 25,390 million transistors, close to the RX 7700's 28,100 million.

The memory systems are fundamentally different. The RX 7700 uses 16 GB of GDDR6 on a 256-bit bus, yielding 624.1 GB/s of bandwidth. The Z2 uses 16 GB of LPDDR5X on a 128-bit bus, yielding 119.9 GB/s. The RX 7700's memory clock is 2438 MHz with 19.5 Gbps effective speed. The Z2's memory clock is 937 MHz with 7.5 Gbps effective speed. The RX 7700 has more than five times the memory bandwidth.

The execution resources diverge sharply. The RX 7700 has 2560 shading units, 160 TMUs, 96 ROPs, and 40 ray tracing cores. The Z2 has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores.

Both list FP16 at a 1:1 ratio with FP32.

The physical and power profiles are opposite. The RX 7700 is a dual-slot card with a 200 W TDP, requiring two 8-pin power connectors and a 550 W suggested PSU. It uses a PCIe 4.0 x16 bus interface. The Z2 has no slot width, no power connectors, no bus interface listed, and a 28 W TDP. The RX 7700 has multiple display outputs; the Z2 has one USB Type-C. The RX 7700 was released in September 2025; the Z2 in December 2024.
