AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 4070 Comparison

Head-to-Head Benchmarks

The database does not contain any direct head-to-head benchmark entries for the AMD Ryzen Z2 GPU against the NVIDIA GeForce RTX 4070. The recorded measurements list zero wins for each part, and there are no shared test scores to compare. This absence of overlapping data means a direct numeric comparison cannot be constructed from the database. What can be analyzed is the standalone benchmark profile of the RTX 4070 and the architectural and specification gaps between the two products.

The RTX 4070 has a recorded average benchmark score of 37,648 across its test suite. Its nearest rival in the database is the NVIDIA Tesla P4 with an average score of 37,628, a delta of 0.1%. The RTX 4070 sits 0.4% ahead of the AMD Radeon RX Vega 56, which scores 37,507. It trails the NVIDIA GeForce RTX 4080 Mobile by 1.3%, as that part scores 38,135. The RTX 4070 leads the AMD Radeon PRO W6400 by 1.3%, with that card scoring 37,157. These deltas are tight, indicating the RTX 4070 sits in a cluster where small margins separate the surrounding parts.

The RTX 4070 delivers 29.15 TFLOPS of FP32 performance and 29.15 TFLOPS of FP16 performance at a 1:1 ratio. Its pixel rate is 158.4 GPixel/s and its texture rate is 455.4 GTexel/s. The AMD Ryzen Z2 GPU, by contrast, delivers 8.294 TFLOPS of FP32 and 8.294 TFLOPS of FP16, also at a 1:1 ratio. Its pixel rate is 86.40 GPixel/s and its texture rate is 129.6 GTexel/s. On raw shading throughput, the RTX 4070 holds a 3.5x advantage in FP32 and FP16 compute. In pixel throughput, the RTX 4070 is roughly 1.8x faster, and in texture throughput it is about 3.5x faster.

Memory bandwidth also favors the RTX 4070 by a wide margin. The RTX 4070 uses 12 GB of GDDR6X on a 192-bit bus, yielding 504.2 GB/s. The Ryzen Z2 GPU uses 16 GB of LPDDR5X on a 128-bit bus, yielding 119.9 GB/s. That is a 4.2x bandwidth advantage for the NVIDIA part. The Ryzen Z2 GPU does hold a capacity advantage of 16 GB versus 12 GB, but the bandwidth gap is substantial.

The 3DMark Steel Nomad DX12 score for the RTX 4070 is 3,854. Its Geekbench OpenCL score is 154,858 and its Geekbench Vulkan score is 174,152. PassMark results show a G3D score of 26,927 and a GPU compute score of 14,720. In legacy DirectX tests, the RTX 4070 records 320 in DirectX 9, 244 in DirectX 11, 139 in DirectX 10, and 103 in DirectX 12. The G2D score is 1,164. No equivalent benchmark scores exist for the Ryzen Z2 GPU in the database, so the RTX 4070 cannot be positioned against it with measured test data.

Where Each One Wins

The RTX 4070 wins decisively in every measurable performance category recorded in the database. Its shading unit count is 5,888 versus 768 for the Ryzen Z2 GPU. Texture mapping units stand at 184 versus 48, and raster operation units at 64 versus 32. The RTX 4070 also carries 46 ray tracing cores and 184 tensor cores, while the Ryzen Z2 GPU has 12 ray tracing cores and no tensor cores listed. For any workload that depends on raw compute, texture filtering, or ray tracing throughput, the RTX 4070 is the stronger part.

The Ryzen Z2 GPU wins on memory capacity with 16 GB versus 12 GB. It also wins on power draw, with a TDP of 28 W against 200 W for the RTX 4070. The Ryzen Z2 GPU requires no power connectors, while the RTX 4070 uses a 16-pin connector and a suggested PSU of 550 W. The Ryzen Z2 GPU is also smaller in physical footprint, although the database only lists dimensions for the RTX 4070: 240 mm length, 110 mm height, 40 mm width, dual-slot. The Ryzen Z2 GPU has no listed dimensions, but its power connector absence and 28 W TDP indicate a far more compact design.

The Ryzen Z2 GPU uses LPDDR5X memory, which is lower power than the GDDR6X used by the RTX 4070. The RTX 4070 has a memory clock of 1313 MHz with 21 Gbps effective, while the Ryzen Z2 GPU runs its memory at 937 MHz with 7.5 Gbps effective. The database does not list a launch MSRP for the Ryzen Z2 GPU. The RTX 4070 carries a launch MSRP of 599 USD, stated once here for reference.

Architecture Differences

The AMD Ryzen Z2 GPU is built on the Hawk Point chip using RDNA 3.0 architecture. It is fabricated on a 4 nm process at TSMC with 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6M per mm². The NVIDIA GeForce RTX 4070 uses the AD104 chip with Ada Lovelace architecture. It is fabricated on a 5 nm process at TSMC with 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8M per mm². The Ryzen Z2 GPU has the denser process node at 4 nm versus 5 nm, but the RTX 4070 packs more transistors overall.

Clock behavior differs notably. The Ryzen Z2 GPU has a base clock of 800 MHz and a boost clock of 2700 MHz. The RTX 4070 has a base clock of 1920 MHz and a boost clock of 2475 MHz. Despite a much lower base clock, the Ryzen Z2 GPU boosts higher than the RTX 4070. That higher boost clock does not compensate for the massive difference in shading units and other execution resources.

The Ryzen Z2 GPU is classified as a Console GPU in the AMD generation line. The RTX 4070 belongs to the GeForce 40-series and is marked as end-of-life in production status. The Ryzen Z2 GPU is still active in production. The RTX 4070 lists its predecessor as GeForce 30 and its successor as GeForce 50. The Ryzen Z2 GPU has no predecessor or successor listed.

API support is identical. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the Ryzen Z2 GPU has a single USB Type-C output, while the RTX 4070 has one HDMI 2.1 and three DisplayPort 1.4a outputs. The RTX 4070 uses a PCIe 4.0 x16 bus interface, while the Ryzen Z2 GPU has no bus interface listed.

The Verdict

The data separates these two parts cleanly by role. The NVIDIA GeForce RTX 4070 is a desktop-class GPU with 29.15 TFLOPS of FP32 compute, 504.2 GB/s of memory bandwidth, and a 200 W TDP. It sits at the 81st percentile of all GPUs in the database, with an average benchmark score of 37,648. Its nearest rivals are all within 1.3% of its average score, which places it in a tightly contested performance band. The RTX 4070 is suited to workloads that demand high shading throughput, high texture rates, and ray tracing capability.

The AMD Ryzen Z2 GPU is a 28 W part with 8.294 TFLOPS of FP32 compute and 119.9 GB/s of memory bandwidth. It has no benchmark scores and no nearest rivals recorded in the database, so its relative standing cannot be quantified. Its 16 GB memory capacity and active production status suggest it targets a different segment, likely integrated or low-power console-class systems. The 768 shading units and 12 ray tracing cores are far below the RTX 4070 in raw resources.

For users who need maximum measured performance, the RTX 4070 is the only part with recorded scores, and those scores place it well above the Ryzen Z2 GPU in every compute metric. For users constrained by power or physical footprint, the Ryzen Z2 GPU offers a 28 W design with no power connectors and a smaller memory footprint in terms of power draw. The database does not provide enough data on the Ryzen Z2 GPU to recommend it for performance-focused tasks. The RTX 4070, with its 81st percentile ranking and benchmark suite, is the clear choice when measured performance matters.

The process node difference is notable: the Ryzen Z2 GPU uses 4 nm TSMC while the RTX 4070 uses 5 nm TSMC, yet the RTX 4070 packs 10,410 million more transistors. The Ryzen Z2 GPU has a higher transistor density at 142.6M per mm² versus 121.8M per mm². The RTX 4070 compensates with a much larger die and far more execution resources. The two parts target entirely different power envelopes, with the Ryzen Z2 GPU at 28 W and the RTX 4070 at 200 W. That 172 W gap explains the massive differences in shading units, memory bandwidth, and compute throughput. The RTX 4070 is the only one of the two with recorded benchmark scores in the database, and its 81st percentile ranking reflects a desktop-class part, while the Ryzen Z2 GPU sits at the 50th percentile with no measured tests.
