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

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Ryzen Z2 A GPU and the NVIDIA GeForce RTX 4070 Ti. The RTX 4070 Ti holds an average benchmark score of 44,795, placing it in the 84th percentile of all GPUs in the database. The AMD Ryzen Z2 A GPU has no recorded benchmark scores, and its percentile sits at 50, meaning it falls in the median range based on its hardware characteristics rather than measured results. With no head-to-head benchmark entries available, the comparison relies entirely on the RTX 4070 Ti's measured scores and the architectural data provided.

The RTX 4070 Ti delivers 40.09 TFLOPS of FP32 compute, while the AMD Ryzen Z2 A GPU delivers 1.638 TFLOPS. This represents a 24-fold difference in raw floating-point throughput. In texture processing, the NVIDIA card reaches 626.4 GTexel/s compared to 51.20 GTexel/s for the AMD chip, a 12-fold margin. Pixel throughput tells a similar story: 208.8 GPixel/s versus 25.60 GPixel/s, an 8-fold difference.

Memory bandwidth further separates the two. The RTX 4070 Ti accesses 504.2 GB/s over a 192-bit GDDR6X bus, while the AMD Ryzen Z2 A GPU manages 102.4 GB/s over a 128-bit LPDDR5 bus. The NVIDIA card also carries more memory bandwidth per byte of capacity, as its 12 GB pool operates at roughly 42 GB/s per gigabyte, whereas the AMD chip's 16 GB pool operates at 6.4 GB/s per gigabyte.

The RTX 4070 Ti's measured scores from the database confirm its position. In the 3DMark Steel Nomad DX12 test, it scores 5,024. Geekbench OpenCL and Vulkan results reach 176,953 and 213,808 respectively. Passmark G3D shows 31,624, with GPU compute at 18,396. The AMD Ryzen Z2 A GPU has no comparable recorded measurements, so its performance profile must be inferred from its 1.638 TFLOPS FP32 ceiling and its 15 W TDP.

Where Each One Wins

The RTX 4070 Ti wins outright in every measurable category where data exists. Its nearest rivals in the database, the NVIDIA GeForce RTX 5090 Mobile at 45,152 (0.8% higher), the AMD Radeon Pro 5500 XT at 45,384 (1.3% higher), the NVIDIA RTX A6000 at 44,075 (1.6% lower), and the Intel Arc A730M at 45,592 (1.7% higher), all fall within a narrow band around its average score. This indicates the RTX 4070 Ti sits at the high end of a competitive cluster, within roughly 2% of each adjacent card.

For the AMD Ryzen Z2 A GPU, the only wins are structural rather than performance-based. It offers 16 GB of memory versus 12 GB, which matters for workloads where capacity exceeds bandwidth demands. It also draws 15 W versus 285 W, making it suitable for low-power or portable implementations. Its 7 nm process node and 2,400 million transistors on a 163 mm² die yield a transistor density of 14.7M per mm², a fraction of the NVIDIA card's 121.8M per mm² on a 294 mm² die with 35,800 million transistors.

The use-case split is stark. The RTX 4070 Ti is built for high-resolution rendering, ray tracing, and compute-heavy applications. Its 60 RT cores and 240 tensor cores provide dedicated hardware for accelerated ray tracing and AI workloads. The AMD chip has 8 RT cores and no tensor cores, limiting its ray tracing throughput and excluding tensor-accelerated features entirely.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Ryzen Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, built on TSMC's 7 nm process. The NVIDIA GeForce RTX 4070 Ti uses the AD104 chip with Ada Lovelace architecture, built on TSMC's 5 nm process. The process node difference directly affects transistor density: the AMD chip packs 2,400 million transistors into 163 mm², while the NVIDIA chip packs 35,800 million transistors into 294 mm².

Shading unit counts diverge dramatically. The AMD chip has 512 shading units, 32 texture mapping units, and 16 render output units. The NVIDIA card has 7,680 shading units, 240 TMUs, and 80 ROPs. This 15-fold difference in shader count explains the proportional FP32 performance gap. Ray tracing hardware differs as well: 8 RT cores on the AMD side versus 60 RT cores on the NVIDIA side. Tensor cores appear only on the NVIDIA card, with 240 units available.

Memory architecture reflects each card's intended role. The AMD chip uses LPDDR5 running at 800 MHz with 6.4 Gbps effective speed, yielding 102.4 GB/s across a 128-bit bus. The NVIDIA card uses GDDR6X at 1,313 MHz with 21 Gbps effective speed, yielding 504.2 GB/s across a 192-bit bus. The RTX 4070 Ti also supports a PCIe 4.0 x16 interface, while the AMD chip lists no bus interface in the database.

FP16 capabilities differ in ratio. The AMD chip achieves 3.277 TFLOPS FP16 at a 2:1 ratio relative to FP32, indicating packed FP16 execution. The NVIDIA card achieves 40.09 TFLOPS FP16 at a 1:1 ratio, meaning full-rate FP16 throughput equal to FP32. This matters for workloads that mix precision levels, such as certain machine learning inference tasks.

API support is identical: both list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the AMD chip offering a single USB Type-C connection and the NVIDIA card offering 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The Verdict

The data supports a clear division of roles. The NVIDIA GeForce RTX 4070 Ti is a high-performance desktop GPU with measured scores across multiple benchmark suites, an 84th percentile rank, and an average score of 44,795. Its nearest rivals sit within 1.7% either direction, confirming its position among top-tier cards. It delivers 40.09 TFLOPS FP32, 626.4 GTexel/s texture rate, 208.8 GPixel/s pixel rate, and 504.2 GB/s memory bandwidth. Its launch MSRP is 799 USD.

The AMD Ryzen Z2 A GPU is a low-power chip with 15 W TDP, 1.638 TFLOPS FP32, and 102.4 GB/s memory bandwidth. It has no recorded benchmark scores and no nearest rivals in the database, leaving its measured performance undefined. Its 50th percentile rank reflects a median standing based on specifications, not results. The 16 GB memory capacity is its only numerical advantage, alongside the power draw difference.

Selecting between them depends entirely on the use case. For desktop gaming, ray tracing, compute, or AI acceleration, the RTX 4070 Ti is the only option with recorded performance data, and that data shows a card operating in the upper percentile range. For a low-power embedded or portable application where 15 W is the ceiling, the AMD chip exists in a different performance class entirely. The RTX 4070 Ti is end-of-life per the database, while the AMD chip remains active in production.
