AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the AMD Ryzen Z2 GPU and the NVIDIA GeForce RTX 4070 AD103. Both entries list an empty benchmark array, with zero recorded wins for either side. Consequently, there are no numerical scores, frame rates, or performance deltas to compare across the two products.

What can be established from the available data is the theoretical compute ceiling of each design. The NVIDIA part delivers 29.15 TFLOPS of FP32 throughput, which is approximately 3.5 times the 8.294 TFLOPS of the AMD part. This is a fundamental arithmetic gap that suggests a substantial performance advantage for the NVIDIA GPU in any workload that scales with raw shader throughput. Similarly, the texture rate of the NVIDIA GPU, at 455.4 GTexel/s, is roughly 3.5 times the 129.6 GTexel/s of the AMD GPU. The pixel rate difference is narrower but still significant: 158.4 GPixel/s versus 86.40 GPixel/s, a 1.8x advantage for NVIDIA.

The memory subsystem presents a contrasting picture. The AMD Ryzen Z2 GPU carries 16 GB of LPDDR5X memory, while the NVIDIA GeForce RTX 4070 AD103 carries 12 GB of GDDR6X memory. However, the NVIDIA GPU has a 192-bit bus width versus the AMD GPU's 128-bit bus, and the NVIDIA memory clock is rated at 1313 MHz (21 Gbps effective) compared to the AMD's 937 MHz (7.5 Gbps effective). The result is a memory bandwidth of 504.2 GB/s for the NVIDIA part versus 119.9 GB/s for the AMD part, a 4.2x difference. The NVIDIA GPU is overwhelmingly superior in bandwidth, while the AMD GPU offers a larger capacity pool.

The absence of benchmark scores means no percentile ranking or rival comparison data is available for either product. The database shows both at the 50th percentile against all GPUs, but this is a default placeholder without any underlying measurements. The analysis must therefore rely on the architectural specifications to infer relative performance characteristics.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The AMD Ryzen Z2 GPU uses the RDNA 3.0 architecture, fabricated on a 4 nm process at TSMC. The chip, codenamed Hawk Point, integrates 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The NVIDIA GeForce RTX 4070 AD103 uses the Ada Lovelace architecture, also fabricated at TSMC but on a 5 nm process. Its AD103 chip contains 45,900 million transistors on a 379 mm² die, with a transistor density of 121.1 million per square millimeter. The AMD chip achieves higher density on a smaller die, while the NVIDIA chip is substantially larger and packs nearly double the transistor count.

The compute unit configurations differ sharply. The AMD GPU has 768 shading units, 48 texture mapping units, and 32 ROPs. It also includes 12 dedicated ray tracing cores. The NVIDIA GPU has 5,888 shading units, 184 TMUs, and 64 ROPs, along with 46 RT cores and 184 tensor cores. The NVIDIA part has roughly 7.7 times the shader count, 3.8 times the TMUs, and 2 times the ROPs of the AMD part. The NVIDIA GPU also adds tensor cores, which the AMD GPU lacks entirely, indicating a clear feature gap for AI-accelerated workloads.

Memory architecture is another major divider. The AMD Ryzen Z2 GPU uses LPDDR5X memory with a 128-bit interface and a 119.9 GB/s bandwidth. The NVIDIA GeForce RTX 4070 AD103 uses GDDR6X memory with a 192-bit interface and a 504.2 GB/s bandwidth. The NVIDIA part also has a substantially higher effective memory clock rate: 21 Gbps versus 7.5 Gbps. The AMD part compensates with 16 GB of capacity versus 12 GB, but the bandwidth deficit is large enough to affect high-resolution texture streaming and frame buffer operations.

Power delivery and physical design also diverge. The AMD GPU has a TDP of 28 W and requires no power connectors. The NVIDIA GPU has a TDP of 200 W and uses a single 16-pin power connector, with a suggested power supply of 550 W. The NVIDIA card is a dual-slot design measuring 240 mm in length, 110 mm in height, and 40 mm in width. The AMD GPU has no listed slot width or dimensions, consistent with it being an integrated or embedded-class solution rather than a discrete add-in board. The bus interface for the NVIDIA part is PCIe 4.0 x16; the AMD part has no bus interface listed.

The display outputs also differ. The AMD GPU provides a single USB Type-C output. The NVIDIA GPU provides one HDMI 2.1 output and three DisplayPort 1.4a outputs, supporting multi-monitor configurations. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical.

The Verdict

The data points to two products with entirely different scopes. The AMD Ryzen Z2 GPU, with its 28 W TDP, 16 GB of LPDDR5X, and a single USB Type-C output, is positioned for low-power, compact systems. Its 8.294 TFLOPS of FP32 performance and 119.9 GB/s of memory bandwidth are modest figures. The NVIDIA GeForce RTX 4070 AD103, with a 200 W TDP, 504.2 GB/s of bandwidth, and 29.15 TFLOPS, is a high-performance discrete graphics card aimed at demanding desktop workloads.

For users who need maximum raw graphics throughput, the NVIDIA GPU is the only viable choice based on the recorded specifications. It dominates in every compute and memory throughput metric: shader count, texture rate, pixel rate, RT cores, tensor cores, and bandwidth. The 4.2x bandwidth advantage and 3.5x FP32 advantage are decisive for gaming at high resolutions or for GPU-accelerated compute tasks. The NVIDIA part also supports multi-display setups with its four video outputs.

For users who prioritize memory capacity and power efficiency, the AMD GPU has clear advantages. Its 16 GB capacity exceeds the NVIDIA's 12 GB, which can matter for large datasets or high-texture workloads that fit within the slower memory. Its 28 W TDP is a fraction of the NVIDIA's 200 W, and the lack of a power connector means it can be deployed in systems without dedicated GPU power delivery. The AMD part also has a higher transistor density, indicating a more compact design.

The production status differs as well: the AMD Ryzen Z2 GPU is listed as Active, while the NVIDIA GeForce RTX 4070 AD103 is listed as End-of-life. The release dates show the AMD part arriving later, in 2024-12-31, versus the NVIDIA part's 2024-02-29. The NVIDIA part has a successor in the GeForce 50 series, while the AMD part has no successor listed. Neither product has an average benchmark score or a launch MSRP in the database, so no pricing-based judgment can be made.

The verdict from the data is straightforward: the NVIDIA GPU is the higher-performance part by a wide margin, while the AMD GPU is the lower-power, higher-capacity alternative. Any purchase decision depends entirely on the target workload and power envelope, but the recorded specifications do not suggest parity in raw performance.
