AMD Radeon RX 7700S vs AMD Ryzen Z2 GPU Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon RX 7700S and the AMD Ryzen Z2 GPU. The head-to-head field is empty, and neither product records a win in matched testing. This absence of comparative data is itself informative: the two parts occupy different measurement universes within the database. The RX 7700S has three recorded benchmark scores, while the Ryzen Z2 GPU has none. Any direct comparison must therefore rely on the RX 7700S absolute scores, its percentile ranking, and the architectural specifications of both parts.

The RX 7700S delivers a 3DMark Steel Nomad DX12 score of 2185. In Geekbench, it records 62983 in OpenCL and 36380 in Vulkan. Its average benchmark score across all recorded tests is 33849. That average places it at the 78th percentile among all GPUs in the database. The nearest rivals in the database are instructive. The AMD Radeon HD 7950 scores 33951, a delta of -0.3% relative to the RX 7700S. The AMD Radeon RX 480 scores 33997, a delta of -0.4%. The NVIDIA GeForce GTX 1060 5 GB scores 33694, a delta of +0.5%. The NVIDIA RTX A5000 scores 33622, a delta of +0.7%. These deltas are all within a single percentage point, indicating that the RX 7700S average score sits in a tight cluster with older and mid-range desktop parts from previous generations. The RX 7700S is not dramatically ahead of these rivals; it is effectively at parity, with a slight edge over the GTX 1060 5 GB and the RTX A5000, and a fractional deficit against the HD 7950 and RX 480.

The Ryzen Z2 GPU has no benchmark scores, no average score, and no nearest rivals. Its percentile rank of 50 is the median default for an unmeasured part. This means the database cannot quantify its performance relative to the RX 7700S or any other GPU. The Z2 GPU is a console-class integrated part, and the data simply does not include performance measurements for it. What the data does show is a structural difference: the RX 7700S is a discrete mobile GPU with a full benchmark profile, while the Z2 GPU is an unmeasured integrated graphics solution.

Where Each One Wins

Based strictly on recorded data, the RX 7700S wins every measurable category. It has benchmark scores; the Z2 GPU has none. It has a 78th percentile ranking; the Z2 GPU sits at the 50th percentile default. It has a defined average score of 33849; the Z2 GPU average is recorded as 0. The RX 7700S also wins on raw compute metrics. Its FP32 throughput is 20.48 TFLOPS, compared to 8.294 TFLOPS for the Z2 GPU. Its pixel rate is 160.0 GPixel/s versus 86.40 GPixel/s. Its texture rate is 320.0 GTexel/s versus 129.6 GTexel/s. Its memory bandwidth is 288.0 GB/s versus 119.9 GB/s. These are not close margins; the RX 7700S more than doubles the Z2 GPU in FP32 throughput and texture rate, and nearly doubles it in pixel rate and memory bandwidth.

The Z2 GPU wins on power efficiency and integration. Its TDP is 28 W, compared to 100 W for the RX 7700S. That is a 72 W difference in favor of the Z2 GPU. The Z2 GPU also uses a 4 nm process node from TSMC, versus 6 nm for the RX 7700S. The Z2 GPU packs 25,390 million transistors into a 178 mm² die, yielding a transistor density of 142.6M per mm². The RX 7700S has 13,300 million transistors on a 204 mm² die, at a density of 65.2M per mm². The Z2 GPU is significantly denser, which aligns with its integrated, low-power positioning.

The use-case split is clear. The RX 7700S is for scenarios where absolute performance matters, such as gaming on a portable device with a discrete GPU. The Z2 GPU is for scenarios where power draw and integration are paramount, such as a console or handheld with an APU. The data does not show the Z2 GPU winning any performance benchmark, but it does show it winning on power and process technology.

Bus interface: the RX 7700S is PCIe 4.0 x16, the Z2 GPU has no listed bus interface. Release date: the RX 7700S launched on 2023-01-03, the Z2 GPU on 2024-12-31. Both use the same architecture, RDNA 3.0, and both come from AMD. Both have no power connectors listed, and both have no suggested PSU.

Architecture Differences

The RX 7700S is built on the Navi 33 chip, with the codename Hotpink Bonefish, and belongs to the Radeon RX 7000 series under the Navi Mobile (RX 7000M) generation. The Ryzen Z2 GPU is built on the Hawk Point chip, with no codename listed, and belongs to the Console GPU (AMD) generation. Both use RDNA 3.0 architecture and are fabricated by TSMC, but on different nodes: 6 nm for the RX 7700S, 4 nm for the Z2 GPU. The transistor density difference is stark: 65.2M per mm² versus 142.6M per mm². The Z2 GPU packs nearly double the transistors per square millimeter, which is consistent with a more advanced process.

The RX 7700S has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The RX 7700S has more than 2.5 times the shading units and TMUs, and more than double the ROPs and ray tracing cores. The FP16 ratio also differs: the RX 7700S has a 2:1 FP16 to FP32 ratio, while the Z2 GPU has a 1:1 ratio. This means the RX 7700S doubles its FP32 throughput when running FP16 workloads, reaching 40.96 TFLOPS, while the Z2 GPU remains at 8.294 TFLOPS in both.

The memory subsystem reflects the different approaches. The RX 7700S uses GDDR6 with a 128 bit bus and 288.0 GB/s bandwidth. The Z2 GPU uses LPDDR5X with a 128 bit bus but only 119.9 GB/s bandwidth. The Z2 GPU has twice the memory capacity (16 GB versus 8 GB), but the RX 7700S has more than double the bandwidth. The RX 7700S base clock is 1500 MHz, boost clock is 2500 MHz, and game clock is 2200 MHz. The Z2 GPU base clock is 800 MHz, boost clock is 2700 MHz, and it has no game clock listed. The Z2 GPU boost clock is 200 MHz higher, but its base clock is 700 MHz lower.

The Verdict

The data indicates that the AMD Radeon RX 7700S is the performance choice. Its recorded benchmarks show an average score of 33849 at the 78th percentile, with specific scores of 2185 in 3DMark Steel Nomad DX12, 62983 in Geekbench OpenCL, and 36380 in Geekbench Vulkan. Its FP32 throughput of 20.48 TFLOPS, texture rate of 320.0 GTexel/s, and memory bandwidth of 288.0 GB/s are all substantially higher than the corresponding values for the Z2 GPU. The RX 7700S also has more shading units, TMUs, ROPs, and ray tracing cores. Anyone seeking raw graphics performance from the database should select the RX 7700S.

The AMD Ryzen Z2 GPU is the integration and efficiency choice. Its TDP of 28 W is less than a third of the RX 7700S TDP of 100 W. It uses a 4 nm process with a higher transistor density of 142.6M per mm². It offers 16 GB of memory, double the RX 7700S capacity, and a higher boost clock of 2700 MHz. The Z2 GPU has no benchmark scores in the database, so its performance cannot be quantified. The data supports its use in low-power, compact designs where the RX 7700S power draw would be prohibitive.

The database does not provide a head-to-head comparison, and the Z2 GPU has no performance data. The verdict follows the available evidence: the RX 7700S wins on every measurable performance metric, while the Z2 GPU wins on power consumption, process node, and memory capacity. The choice depends on whether the priority is performance or efficiency, and the data only supports the performance claim for the RX 7700S.
