AMD Ryzen Z2 Extreme GPU vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data places these two processors in completely different performance tiers. The AMD Ryzen Z2 Extreme GPU produces an average benchmark score of 516, while the NVIDIA GeForce RTX 5070 Mobile averages 29,928. That is a 5,700% gap in aggregate score, a difference large enough to place them in separate categories of the database rather than as direct competitors.

The AMD part's only recorded benchmark, 3DMark Steel Nomad DX12, returns a score of 516. Its nearest rivals in the database are all legacy desktop and mobile parts. It sits 3.4% behind the Intel HD Graphics P4000, 3.7% behind the AMD Radeon HD 6870, and 9.3% behind the AMD Radeon HD 6770M. The only rival it beats in its immediate tier is the AMD Radeon HD 6750M, where it leads by 6.6%. The percentile ranking of 1 means it outperforms roughly 1% of all GPUs in the database. These figures indicate an entry-level integrated solution.

The NVIDIA GeForce RTX 5070 Mobile, by contrast, sits at the 75th percentile of all GPUs. Its nearest rivals are desktop-class discrete cards from previous generations. The RTX 5070 Mobile trails the NVIDIA GeForce RTX 3070 Ti by 0.1%, runs 0.5% ahead of the RTX 2080 Ti, sits 0.6% behind the AMD Radeon RX 6800, and is 1.7% behind the AMD Radeon RX 6700. These delta values are tiny, meaning the RTX 5070 Mobile performs within a few percentage points of those established desktop parts.

The RTX 5070 Mobile's individual benchmark results show its strongest areas. It scores 122,238 in Geekbench OpenCL and 116,960 in Geekbench Vulkan. In Passmark G3D it reaches 20,355, with GPU compute at 8,279. Legacy DirectX tests are comparatively weaker: 214 in DirectX 9, 192 in DirectX 11, 129 in DirectX 10, and 93 in DirectX 12. The 2D score of 896 reflects a typical integrated-class output for that metric. The spread between compute-heavy workloads and older API tests indicates the architecture favors modern parallel workloads over legacy rasterization paths.

When comparing the two directly, the RTX 5070 Mobile's FP32 throughput of 13.13 TFLOPS is 2.37 times the Z2 Extreme's 5.530 TFLOPS. Texture rate favors the NVIDIA part similarly: 205.2 GTexel/s versus 172.8 GTexel/s. The one rasterization metric where AMD leads is pixel rate, 129.6 GPixel/s versus 68.40 GPixel/s, a 1.9x advantage. This suggests the Z2 Extreme's smaller shading unit count but higher pixel output per clock gives it an unusual profile: weak compute, moderate texturing, strong pixel fill.

Architecture Differences

The two processors use different foundry nodes and different architectural generations. The AMD Ryzen Z2 Extreme is built on TSMC's 4 nm process and uses the RDNA 3.5 architecture with a chip labeled Strix Point. It belongs to the Console GPU (AMD) generation. The NVIDIA GeForce RTX 5070 Mobile is fabricated on TSMC's 5 nm process, uses the Blackwell 2.0 architecture, and carries the GB206 chip. It belongs to the GeForce 50 Mobile generation.

Transistor counts differ substantially. The AMD chip contains 34,000 million transistors on a 233 mm² die, yielding a density of 145.9 million transistors per square millimeter. The NVIDIA chip contains 21,900 million transistors on a 181 mm² die, for a density of 121.0 million per square millimeter. The AMD die is larger and denser, yet its performance profile is far below the NVIDIA part, indicating that architectural efficiency and resource allocation matter more than raw transistor count.

Core configurations diverge sharply. The Z2 Extreme has 1,024 shading units, 64 texture mapping units, 48 ROPs, and 16 ray tracing cores. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores. The NVIDIA part carries 4.5 times the shading units and 2.25 times the ray tracing cores. The AMD part has no tensor cores listed, while the NVIDIA part includes a full tensor core array, a structural difference for AI workloads.

Memory architecture also separates the two. The AMD part uses 16 GB of LPDDR5X on a 128-bit bus, delivering 128.0 GB/s of bandwidth. The NVIDIA part uses 8 GB of GDDR7 on the same 128-bit bus width but delivers 384.0 GB/s, exactly three times the bandwidth. The AMD part uses more capacity but far less bandwidth. Clock behavior reflects their different roles: the Z2 Extreme boosts to 2700 MHz from an 800 MHz base, while the RTX 5070 Mobile boosts to 1425 MHz from a 907 MHz base. The AMD part's higher boost clock does not compensate for its lower execution resource count.

Power and integration differ as well. The AMD part has a 28 W TDP and a single USB Type-C display output. The NVIDIA part has a 50 W TDP, uses a PCIe 5.0 x16 bus interface, and lists its display outputs as portable device dependent. Both use no external power connectors. The NVIDIA part is classified as an IGP slot width, indicating an integrated or embedded form factor despite its desktop-class performance tier.

The Verdict

The data separates these two processors into distinct roles. The AMD Ryzen Z2 Extreme GPU, with a 1st percentile ranking and an average score of 516, is positioned as an entry-level integrated graphics solution. Its 28 W TDP, single display output, and 16 GB of LPDDR5X memory suggest a low-power embedded or handheld console context. Its high pixel rate of 129.6 GPixel/s relative to its compute throughput indicates a design tuned for lightweight 2D rendering and simple raster workloads rather than heavy 3D compute.

The NVIDIA GeForce RTX 5070 Mobile, at the 75th percentile with an average score of 29,928, performs at the level of previous-generation desktop flagships. Its nearest rivals, the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700, are all within 1.7% of its score. This places it in a high-performance mobile tier despite its 50 W TDP. The presence of 144 tensor cores and 36 ray tracing cores, along with triple the memory bandwidth, gives it a structural advantage for modern graphics features and AI-adjacent workloads.

The verdict from the recorded data is unambiguous: the RTX 5070 Mobile outperforms the Z2 Extreme by several orders of magnitude in aggregate benchmarks and in nearly every compute metric. The Z2 Extreme only wins in pixel rate, memory capacity, boost clock, and transistor density. Those wins do not translate into competitive 3D performance.

Where Each One Wins

The AMD Ryzen Z2 Extreme GPU wins in scenarios where pixel throughput matters more than shader compute. Its 129.6 GPixel/s pixel rate, achieved with only 1,024 shading units, suggests it can handle high-resolution 2D output and simple 3D scenes efficiently. Its 16 GB memory capacity provides ample storage for framebuffers or data sets that do not require high bandwidth. Its 28 W TDP makes it suitable for power-constrained environments where the 50 W NVIDIA part would exceed thermal or battery budgets. Its 4 nm process and higher transistor density indicate a more compact, dense implementation per square millimeter.

The NVIDIA GeForce RTX 5070 Mobile wins in every compute-heavy scenario. Its 13.13 TFLOPS FP32 throughput is 2.37 times the AMD part. Its 384.0 GB/s bandwidth is three times higher, which directly benefits texture-heavy workloads and large data movement. Its 4,608 shading units, 144 TMUs, 36 ray tracing cores, and 144 tensor cores enable features the AMD part cannot match, including ray tracing and tensor-accelerated operations. Its benchmark scores in Geekbench OpenCL and Vulkan, 122,238 and 116,960 respectively, show strong performance in modern API workloads. Its Passmark G3D score of 20,355 places it in the same class as desktop GPUs from the RTX 30 and RX 6000 series.

The use-case split follows the specification differences. The Z2 Extreme suits lightweight rendering, low-power operation, and tasks that benefit from its high pixel fill rate and large memory pool. The RTX 5070 Mobile suits demanding 3D rendering, modern API workloads, ray tracing, and compute-heavy applications where bandwidth and shader throughput dominate. The database's recorded measurements leave no overlap between these roles.
