AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 4070 SUPER Comparison

Where Each One Wins

The recorded data presents a stark contrast between these two GPUs. The AMD Ryzen Z2 A GPU occupies the 50th percentile of all GPUs in the database, while the NVIDIA GeForce RTX 4070 SUPER sits at the 83rd percentile. This gap in overall standing reflects a fundamental difference in purpose and capability.

The NVIDIA GeForce RTX 4070 SUPER wins every recorded benchmark comparison. Its average benchmark score of 43,223 dwarfs the AMD part, which has no recorded benchmark scores in the database. The RTX 4070 SUPER delivers a full range of DirectX results across multiple API levels: PassMark DirectX 9 at 344, DirectX 10 at 167, DirectX 11 at 273, and DirectX 12 at 110. It also posts substantial compute results, including a PassMark GPU Compute score of 17,108 and a Geekbench OpenCL score of 172,795.

The AMD Ryzen Z2 A GPU, by contrast, has zero entries in the benchmark database. This means the only measurable comparison comes from the specification sheets. The AMD part targets a completely different use case: a 15 W TDP with a 7 nm TSMC process and RDNA 2.0 architecture. Its performance class aligns with low-power, integrated-style deployments rather than discrete desktop graphics.

For gaming at high resolutions and demanding settings, the RTX 4070 SUPER clearly dominates. Its 35.48 TFLOPS FP32 throughput and 554.4 GTexel/s texture rate indicate a GPU designed for heavy rasterization workloads. The AMD part delivers 1.638 TFLOPS FP32, which represents a fundamentally different performance tier. The use-case split is straightforward: the RTX 4070 SUPER handles high-end desktop gaming and compute, while the Ryzen Z2 A GPU serves ultra-low-power environments where the 15 W envelope is the primary constraint.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. However, the RTX 4070 SUPER has a complete set of recorded measurements that establish its performance envelope. Its most significant result is the Geekbench Vulkan score of 205,624, which represents the highest single test figure recorded. The Geekbench OpenCL result of 172,795 follows closely, indicating strong general-purpose compute capability.

The PassMark suite reveals a mixed profile across API generations. The DirectX 9 score of 344 exceeds the DirectX 11 score of 273, which in turn beats the DirectX 10 result of 167. The DirectX 12 score of 110 sits lower, suggesting that legacy API paths receive strong optimization while newer pathways may not fully utilize the hardware. The PassMark G3D score of 29,995 provides a comprehensive overall graphics measurement, while the G2D score of 1,184 covers 2D operations.

The RTX 4070 SUPER maintains a consistent performance tier relative to its nearest rivals in the database. The Quadro M6000 24 GB averages 43,262, a delta of -0.1% from the RTX 4070 SUPER's 43,223. The GeForce RTX 5050 Mobile averages 43,268, also a -0.1% delta. The Quadro M6000 averages 43,301, a -0.2% delta, and the GeForce RTX 4090 Mobile averages 43,667, a -1% delta. This clustering indicates that the RTX 4070 SUPER sits squarely within a competitive performance band for high-end GPUs, with no rival in its immediate vicinity exceeding it by more than 1%.

The AMD Ryzen Z2 A GPU has no benchmark scores, no nearest rivals, and no percentile ranking against comparable parts beyond its overall 50th percentile position. The recorded data simply does not include measurable performance results for this part, so all comparisons must derive from its specification sheet.

Specification Differences

The two GPUs differ in nearly every measurable specification. The AMD Ryzen Z2 A GPU uses the Van Gogh chip on a 7 nm TSMC process, while the NVIDIA GeForce RTX 4070 SUPER uses the AD104 chip on a 5 nm TSMC process. Transistor counts diverge sharply: the AMD part has 2,400 million transistors on a 163 mm² die, yielding a density of 14.7 million transistors per square millimeter. The NVIDIA part has 35,800 million transistors on a 294 mm² die, yielding a density of 121.8 million per square millimeter.

Clock speeds show the RTX 4070 SUPER operating at a base of 1980 MHz and boost of 2475 MHz, compared to the AMD part's base of 1000 MHz and boost of 1600 MHz. Memory clocks also differ: the AMD part runs at 800 MHz with 6.4 Gbps effective, while the NVIDIA part runs at 1313 MHz with 21 Gbps effective.

Memory capacity and type diverge completely. The AMD Ryzen Z2 A GPU has 16 GB of LPDDR5 on a 128-bit bus. The RTX 4070 SUPER has 12 GB of GDDR6X on a 192-bit bus. Bandwidth figures reflect this: 102.4 GB/s for AMD versus 504.2 GB/s for NVIDIA.

The compute pipeline shows massive differences in resource counts. The AMD part has 512 shading units, 32 TMUs, 16 ROPs, and 8 RT cores, with no tensor cores listed. The RTX 4070 SUPER has 7,168 shading units, 224 TMUs, 80 ROPs, 56 RT cores, and 224 tensor cores. Pixel rates are 25.60 GPixel/s versus 198.0 GPixel/s, and texture rates are 51.20 GTexel/s versus 554.4 GTexel/s.

Physical and interface specifications also differ. The AMD part has a single USB Type-C display output and no listed bus interface, slot width, power connectors, or dimensions. The RTX 4070 SUPER has a dual-slot design, a 16-pin power connector, a 550 W suggested PSU, PCIe 4.0 x16 interface, and dimensions of 267 mm by 112 mm by 42 mm. Its display outputs include one HDMI 2.1 and three DisplayPort 1.4a.

Architecture Differences

The architectural divide between these GPUs is fundamental. The AMD Ryzen Z2 A GPU uses RDNA 2.0, an architecture designed for efficiency in constrained power envelopes. Its 15 W TDP places it in the ultra-low-power segment, where the 7 nm manufacturing process and modest transistor count of 2,400 million support a compact 163 mm² die. The RDNA 2.0 design implements 8 RT cores and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The NVIDIA GeForce RTX 4070 SUPER uses Ada Lovelace, NVIDIA's architecture for high-performance desktop graphics. The 5 nm process enables 35,800 million transistors on a 294 mm² die, achieving a transistor density of 121.8 million per square millimeter, more than eight times the density of the AMD part. This density supports 56 RT cores and 224 tensor cores, the latter enabling dedicated AI acceleration that the AMD part lacks entirely.

FP16 compute reveals a notable architectural choice. The AMD Ryzen Z2 A GPU delivers 3.277 TFLOPS FP16 using a 2:1 ratio relative to FP32, indicating packed math where two FP16 operations share FP32 hardware. The RTX 4070 SUPER delivers 35.48 TFLOPS FP16 at a 1:1 ratio, meaning it processes FP16 at the same rate as FP32, a hallmark of dedicated tensor core designs.

Memory architecture differs in type and purpose. The AMD part uses LPDDR5, a low-power memory standard suited to its 15 W envelope, paired with a 128-bit bus to reach 102.4 GB/s. The RTX 4070 SUPER uses GDDR6X, a high-bandwidth standard that, combined with a 192-bit bus, reaches 504.2 GB/s, nearly five times the bandwidth. The AMD part's 16 GB capacity exceeds the RTX 4070 SUPER's 12 GB, but the bandwidth differential dominates practical performance.

The production timelines also differ. The AMD Ryzen Z2 A GPU released on 2024-12-31 and remains Active. The RTX 4070 SUPER released on 2024-01-16, is now End-of-life, and has a successor in the GeForce 50 series. The RTX 4070 SUPER carries a launch MSRP of 599 USD. The AMD part has no listed launch price. The RTX 4070 SUPER's predecessor is the GeForce 30 series, while the AMD part lists no predecessor or successor. These architectural differences explain the performance gap: the RTX 4070 SUPER pairs a dense 5 nm process with high-bandwidth memory and tensor cores, while the AMD part prioritizes minimal power draw and thermal footprint.
