AMD Ryzen Z2 Extreme GPU vs NVIDIA GeForce RTX 4070 AD103 Comparison

AMD Ryzen Z2 Extreme GPU and NVIDIA GeForce RTX 4070 AD103 occupy opposite ends of the performance spectrum. The database records a single 3DMark Steel Nomad DX12 score for the AMD part at 516 points, placing it in the 1st percentile of all GPUs. The NVIDIA part has no recorded benchmark scores in the database, with a 50th percentile standing, indicating a mid-pack position relative to all tracked GPUs. These two products are not direct competitors by any measurable performance metric, yet their architectural and specification differences provide a clear study in design intent: one is a low-power console-class integrated GPU, the other a full-size discrete desktop graphics card.

Where Each One Wins

The AMD Ryzen Z2 Extreme GPU wins in the categories of power efficiency, integration, and portability. Its recorded thermal design power is 28 W, which is a fraction of the 200 W consumed by the NVIDIA GeForce RTX 4070 AD103. The AMD part draws its power through no external connectors, relying entirely on the motherboard or system power delivery, while the NVIDIA card requires a single 16-pin power connector. The AMD chip is built on a smaller 4 nm process node from TSMC, compared to the 5 nm node used by the NVIDIA chip, giving it a density advantage of 145.9 million transistors per square millimeter versus 121.1 million. The AMD GPU integrates 34,000 million transistors on a 233 mm² die, while the NVIDIA chip packs 45,900 million transistors across a larger 379 mm² die.

The NVIDIA GeForce RTX 4070 AD103 wins decisively in raw compute performance, memory bandwidth, and feature throughput. Its FP32 compute is 29.15 TFLOPS, more than five times the 5.530 TFLOPS of the AMD part. Texture rate reaches 455.4 GTexel/s against 172.8 GTexel/s, and pixel rate is 158.4 GPixel/s versus 129.6 GPixel/s. The NVIDIA card also carries dedicated tensor cores, 184 of them, a resource the AMD GPU lacks entirely. In memory, the NVIDIA part uses a 192-bit bus with GDDR6X memory delivering 504.2 GB/s, while the AMD GPU uses a 128-bit LPDDR5X bus at 128.0 GB/s. The NVIDIA card offers more display outputs with 1x HDMI 2.1 and 3x DisplayPort 1.4a, compared to a single USB Type-C output on the AMD chip.

Architecture Differences

The AMD Ryzen Z2 Extreme GPU uses the RDNA 3.5 architecture, manufactured on a TSMC 4 nm process. It is built on the Strix Point chip and belongs to the console GPU generation. The shader array consists of 1024 shading units, 64 texture mapping units, and 48 render output units. Ray tracing is handled by 16 dedicated RT cores. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its clock behavior shows an 800 MHz base and 2700 MHz boost, with memory running at 1000 MHz (8 Gbps effective).

The NVIDIA GeForce RTX 4070 AD103 uses the Ada Lovelace architecture on a TSMC 5 nm process. The chip is the AD103, part of the GeForce 40-series generation. The compute configuration is substantially larger: 5888 shading units, 184 texture mapping units, and 64 render output units. Ray tracing is served by 46 RT cores, and 184 tensor cores handle AI workloads. Clock speeds start at 1920 MHz base and boost to 2475 MHz. Memory runs at 1313 MHz (21 Gbps effective). The card is a dual-slot design measuring 240 mm in length, 110 mm in height, and 40 mm in width. It connects through PCIe 4.0 x16 and carries a suggested power supply rating of 550 W.

Both products list the same API support generation: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The transistor density difference favors the AMD chip. The AMD GPU has no tensor cores, while the NVIDIA card fields 184 of them, a structural difference that affects any workload relying on tensor operations.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Ryzen Z2 Extreme GPU and the NVIDIA GeForce RTX 4070 AD103. The AMD part has one recorded benchmark result: 3DMark Steel Nomad DX12 at 516 points. This score places it in the 1st percentile of all GPUs. Its nearest rivals in the database are all older or lower-end parts. The Intel HD Graphics P4000 scores 534 points, which is 3.4% ahead of the AMD GPU. The AMD Radeon HD 6870 scores 536 points, 3.7% ahead. The AMD Radeon HD 6750M scores 484 points, meaning the Ryzen Z2 Extreme GPU is 6.6% faster than that part. The AMD Radeon HD 6770M scores 569 points, putting it 9.3% ahead of the Ryzen Z2 Extreme GPU.

The NVIDIA GeForce RTX 4070 AD103 has no recorded benchmark scores in the database, and no nearest rivals are listed. Its 50th percentile standing is a positional marker, not a measured result. The absence of benchmark data for the NVIDIA card means a direct numerical comparison between these two products cannot be constructed from the database. What can be stated is the relative positioning: the AMD part sits at the 1st percentile, the NVIDIA part at the 50th. The gap in compute resources, 5.530 TFLOPS against 29.15 TFLOPS, and bandwidth, 128.0 GB/s against 504.2 GB/s, aligns with that percentile separation.

The Verdict

The data shows two products built for different purposes. The AMD Ryzen Z2 Extreme GPU is a low-power integrated part with a 28 W TDP, no external power requirement, and a single USB Type-C display output. Its 1st percentile benchmark standing and 516-point Steel Nomad score place it among entry-level or legacy graphics hardware. The 16 GB of LPDDR5X memory is its largest capacity asset, but the 128.0 GB/s bandwidth limits sustained throughput.

The NVIDIA GeForce RTX 4070 AD103 is a discrete desktop card with a 200 W TDP, dual-slot cooler, and 240 mm length. Its 29.15 TFLOPS FP32 compute, 504.2 GB/s memory bandwidth, 184 tensor cores, and 46 RT cores position it as a mid-pack performer at the 50th percentile. The 12 GB GDDR6X memory is smaller in capacity but substantially faster in bandwidth. The card supports PCIe 4.0 x16 and provides multiple display outputs.

A user selecting between these two is not choosing between similar products. The AMD part suits systems where power draw and physical footprint are the primary constraints. The NVIDIA card suits systems where compute throughput, memory bandwidth, and tensor capabilities are required. The absence of head-to-head benchmark data prevents a direct performance delta from being stated, but the specification gap in every compute and memory metric points to the NVIDIA card as the higher-performing part. The AMD part holds advantages in transistor density, process node size, memory capacity, and power draw. The NVIDIA part holds advantages in every throughput category and in feature resources.
