AMD Radeon RX 7700S vs AMD Ryzen Z2 A GPU Comparison

The Verdict

The recorded data positions the AMD Radeon RX 7700S as a dedicated mobile graphics solution with a strong performance percentile, while the AMD Ryzen Z2 A GPU appears as a low-power integrated-class part with no recorded benchmark scores in the database. The RX 7700S holds an average benchmark score of 33,849 and sits in the 78th percentile of all GPUs, a figure derived from three benchmark results. The Ryzen Z2 A GPU has an average benchmark score of 0, a 50th percentile placement, and no benchmark entries, meaning the database contains no direct measurement of its performance.

The RX 7700S is the clear choice for any workload requiring sustained graphics throughput, as its 20.48 TFLOPS of FP32 compute, 160.0 GPixel/s pixel rate, and 320.0 GTexel/s texture rate far exceed the Ryzen Z2 A GPU's 1.638 TFLOPS, 25.60 GPixel/s, and 51.20 GTexel/s. The Ryzen Z2 A GPU, with a 15 W TDP and 16 GB of LPDDR5 memory, targets a different segment entirely, one where power draw and memory capacity matter more than raw rasterization speed. The data shows no overlap in their intended use cases: the RX 7700S delivers discrete-level performance in a mobile package, while the Ryzen Z2 A GPU provides a minimal-compute solution with a very low power envelope.

Architecture Differences

The two parts share a common manufacturer and API support, both listing DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but their underlying designs diverge sharply. The RX 7700S uses the Navi 33 chip with RDNA 3.0 architecture, built on a 6 nm TSMC process with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The Ryzen Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, fabricated on a 7 nm TSMC process with 2,400 million transistors on a 163 mm² die, resulting in a transistor density of 14.7M per mm². The RX 7700S packs over five times the transistor count into a larger die, and its density advantage reflects a more advanced process node.

The RX 7700S scales across every compute unit category. It features 2,048 shading units, 128 texture mapping units, 64 render output units, and 32 ray tracing cores. The Ryzen Z2 A GPU has 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores, exactly one quarter of the RX 7700S in each category except ROPs, where it has one quarter as well. Clock speeds tell a similar story. The RX 7700S runs at a 1500 MHz base, 2200 MHz game clock, and 2500 MHz boost, while the Ryzen Z2 A GPU operates at 1000 MHz base and 1600 MHz boost with no game clock listed. The RX 7700S memory clock is 2250 MHz with 18 Gbps effective throughput, whereas the Ryzen Z2 A GPU memory runs at 800 MHz with 6.4 Gbps effective.

Memory configurations differ in capacity and type. The RX 7700S uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Ryzen Z2 A GPU uses 16 GB of LPDDR5 on the same 128-bit bus, but bandwidth drops to 102.4 GB/s. The Ryzen Z2 A GPU doubles the capacity while offering less than half the bandwidth, a trade-off consistent with its 15 W TDP against the RX 7700S's 100 W TDP. The RX 7700S draws power through no external connectors and is classified as an IGP slot width, while the Ryzen Z2 A GPU lists a single USB Type-C display output and no power connector details. Both parts remain in active production, with the RX 7700S released on 2023-01-03 and the Ryzen Z2 A GPU on 2024-12-31.

Head-to-Head Benchmarks

The head-to-head benchmark array is empty, and the wins counters for both parts are zero. The database therefore contains no direct comparison results between the RX 7700S and the Ryzen Z2 A GPU. However, the available benchmark data for the RX 7700S alone provides measurable reference points. In 3DMark Steel Nomad DX12, the RX 7700S scores 2,185. In Geekbench OpenCL, it scores 62,983. In Geekbench Vulkan, it scores 36,380. These three results produce an average benchmark score of 33,849, which places the RX 7700S in the 78th percentile of all GPUs.

The nearest rivals for the RX 7700S, based on average score, are the AMD Radeon HD 7950 at 33,951 with a delta of negative 0.3 percent, the AMD Radeon RX 480 at 33,997 with a delta of negative 0.4 percent, the NVIDIA GeForce GTX 1060 5 GB at 33,694 with a delta of positive 0.5 percent, and the NVIDIA RTX A5000 at 33,622 with a delta of positive 0.7 percent. These figures indicate that the RX 7700S performs within a narrow band around these older discrete cards, trailing the HD 7950 and RX 480 by fractions of a percent while edging out the GTX 1060 5 GB and RTX A5000 by similar margins. The Ryzen Z2 A GPU has no rivals listed and no benchmark scores, so its relative standing cannot be quantified from the database.

The absence of head-to-head data means the only numerical comparison available is through the architectural specifications listed above. The RX 7700S offers 12.5 times the FP32 throughput of the Ryzen Z2 A GPU, 6.25 times the pixel rate, and 6.25 times the texture rate. The RX 7700S also delivers 2.8 times the memory bandwidth. These ratios come directly from the recorded clock, core, and memory specifications.

Where Each One Wins

The RX 7700S wins in every measured performance category from the recorded data. Its 20.48 TFLOPS FP32 output, 40.96 TFLOPS FP16 output, 160.0 GPixel/s pixel rate, and 320.0 GTexel/s texture rate are multiples of the Ryzen Z2 A GPU's corresponding figures of 1.638 TFLOPS, 3.277 TFLOPS, 25.60 GPixel/s, and 51.20 GTexel/s. The RX 7700S also holds the advantage in memory bandwidth at 288.0 GB/s versus 102.4 GB/s, despite the Ryzen Z2 A GPU offering double the memory capacity at 16 GB versus 8 GB. The RX 7700S has a higher base clock of 1500 MHz against 1000 MHz, a higher boost clock of 2500 MHz against 1600 MHz, and a higher memory clock of 2250 MHz against 800 MHz. Its 78th percentile ranking versus the Ryzen Z2 A GPU's 50th percentile placement confirms that the RX 7700S sits above the midpoint of all GPUs, while the Ryzen Z2 A GPU sits exactly at it.

The Ryzen Z2 A GPU wins in power efficiency and memory capacity. Its 15 W TDP is one seventh of the RX 7700S's 100 W TDP, making it suitable for extremely low-power environments. Its 16 GB of LPDDR5 memory doubles the RX 7700S's 8 GB GDDR6 allocation, which may benefit workloads that need larger working sets rather than high bandwidth. The Ryzen Z2 A GPU also uses a smaller die at 163 mm² against 204 mm², though its transistor count is far lower at 2,400 million versus 13,300 million. The Ryzen Z2 A GPU's release date of 2024-12-31 comes later than the RX 7700S's 2023-01-03, but no successor or predecessor data exists for either part.

The RX 7700S is the only one of the two with recorded benchmark scores, giving it a concrete performance profile. The Ryzen Z2 A GPU's empty benchmark array means the database cannot confirm any real-world performance level for it. The RX 7700S outperforms its nearest rivals by small margins, with deltas of positive 0.5 percent against the GTX 1060 5 GB and positive 0.7 percent against the RTX A5000, while trailing the HD 7950 and RX 480 by negative 0.3 percent and negative 0.4 percent respectively. These narrow deltas place the RX 7700S in a tight competitive cluster around these older cards. The Ryzen Z2 A GPU has no such comparison points.

Use cases split cleanly. The RX 7700S serves any scenario where graphics throughput, texture work, pixel fill, and ray tracing capability matter, given its 32 ray tracing cores against 8. The Ryzen Z2 A GPU serves scenarios where power draw is the dominant constraint and memory capacity outweighs bandwidth, given its 15 W TDP and 102.4 GB/s bandwidth. Neither part covers the other's strengths. The data shows no overlap in their performance envelopes.
