AMD Ryzen Z1 Extreme GPU vs NVIDIA GeForce RTX 5070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Ryzen Z1 Extreme GPU and the NVIDIA GeForce RTX 5070 Mobile, with the RTX 5070 Mobile holding every measurable benchmark advantage. The RTX 5070 Mobile posts an average benchmark score of 29,928, placing it in the 75th percentile of all GPUs in the database. The Ryzen Z1 Extreme GPU, by contrast, has no recorded benchmark scores and sits in the 50th percentile, with an average benchmark score of 0. This disparity is not marginal; it reflects a fundamental difference in compute capability, memory bandwidth, and architectural focus.

The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 compute, while the Ryzen Z1 Extreme GPU delivers 8.294 TFLOPS. That is a 58% advantage in raw single-precision throughput, which directly translates to higher frame rates in most rasterized workloads. In FP16 compute, the gap widens further: the RTX 5070 Mobile achieves 13.13 TFLOPS at a 1:1 ratio, while the Ryzen Z1 Extreme GPU reaches 16.59 TFLOPS but only at a 2:1 ratio, meaning it halves its throughput when precision is reduced. The RTX 5070 Mobile’s FP16 output is therefore more consistent across mixed-precision tasks.

Memory bandwidth is another decisive factor. The RTX 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus, delivering 384.0 GB/s. The Ryzen Z1 Extreme GPU uses 16 GB of LPDDR5 on a 64-bit bus, delivering only 51.20 GB/s. That is a 7.5x bandwidth advantage for the RTX 5070 Mobile, which becomes critical in texture-heavy scenes, high-resolution rendering, and compute workloads that stream large datasets. The Ryzen Z1 Extreme GPU’s larger 16 GB capacity does not compensate for its narrow bus and slower memory type, as the bandwidth ceiling limits how quickly data can be fed to the shaders.

The RTX 5070 Mobile also leads in texture and pixel throughput. It produces 205.2 GTexel/s versus 129.6 GTexel/s for the Ryzen Z1 Extreme GPU, a 58% advantage in texture fill. In pixel rate, the Ryzen Z1 Extreme GPU actually posts a higher figure, 86.40 GPixel/s versus 68.40 GPixel/s, which reflects its higher boost clock of 2700 MHz versus 1425 MHz. This means the Ryzen Z1 Extreme GPU can fill more pixels per second in simple, fill-bound scenes, but the RTX 5070 Mobile’s superior texture rate and compute throughput make it the stronger overall rasterizer.

The closest rivals for the RTX 5070 Mobile in the database are the NVIDIA GeForce RTX 3070 Ti, with an average score of 29,945 and a delta of -0.1%, the NVIDIA GeForce RTX 2080 Ti at 29,783 with a delta of 0.5%, the AMD Radeon RX 6800 at 30,095 with a delta of -0.6%, and the AMD Radeon RX 6700 at 30,433 with a delta of -1.7%. These deltas are all within 1.7 percentage points, indicating that the RTX 5070 Mobile performs essentially on par with those desktop-class GPUs from previous generations. The Ryzen Z1 Extreme GPU has no nearest rivals listed in the database, so direct comparative scoring is unavailable, but its 50th percentile standing and zero benchmark average place it well below the RTX 5070 Mobile’s 75th percentile.

The RTX 5070 Mobile’s individual benchmark results reinforce this pattern. Its Geekbench OpenCL score is 122,238, and its Vulkan score is 116,960. In PassMark tests, it scores 20,355 in G3D, 8,279 in GPU compute, 896 in G2D, 214 in DirectX 9, 192 in DirectX 11, 129 in DirectX 10, and 93 in DirectX 12. These numbers show a GPU that is strong in modern API workloads, with the DirectX 12 score being the lowest of the PassMark set, but the overall G3D score of 20,355 is substantial. No comparable benchmark data exists for the Ryzen Z1 Extreme GPU, so the only reliable comparison comes from the architectural specifications and the percentile rankings.

The Verdict

The data indicates a clear hierarchy: the NVIDIA GeForce RTX 5070 Mobile is the substantially stronger GPU for compute-heavy and bandwidth-sensitive workloads. Its 13.13 TFLOPS FP32 throughput, 384.0 GB/s memory bandwidth, and 205.2 GTexel/s texture rate establish it as a high-performance mobile part, sitting in the 75th percentile of all GPUs and performing within 1.7% of desktop-class rivals like the RTX 3070 Ti, RTX 2080 Ti, RX 6800, and RX 6700.

The AMD Ryzen Z1 Extreme GPU, despite its higher boost clock and pixel rate, does not have recorded benchmark scores in the database. Its 50th percentile standing and average benchmark score of 0 indicate that it is not positioned for the same performance class. The Ryzen Z1 Extreme GPU’s 16 GB of memory is its only clear capacity advantage, but the 51.20 GB/s bandwidth severely limits its ability to use that capacity effectively.

For tasks that depend on raw compute, such as rendering, simulation, or machine learning inference, the RTX 5070 Mobile is the correct choice. For scenarios where memory capacity matters more than bandwidth, such as holding large datasets in VRAM, the Ryzen Z1 Extreme GPU offers 16 GB, but the practical benefit is constrained by its narrow 64-bit bus. The RTX 5070 Mobile’s 8 GB of GDDR7 is smaller but far faster, and its 144 tensor cores provide dedicated hardware for AI workloads that the Ryzen Z1 Extreme GPU lacks entirely.

The RTX 5070 Mobile also benefits from a lower transistor count but higher density: it has 21,900 million transistors on a 181 mm² die, while the Ryzen Z1 Extreme GPU has 25,390 million transistors on a 178 mm² die. The Ryzen Z1 Extreme GPU achieves a higher transistor density of 142.6M per mm² versus 121.0M per mm², but that density does not translate into higher performance in the recorded data. The RTX 5070 Mobile’s 50 W TDP is higher than the Ryzen Z1 Extreme GPU’s 30 W, which accounts for its greater compute output.

Specification Differences

The two GPUs differ across nearly every specification field. The AMD Ryzen Z1 Extreme GPU is based on the Phoenix chip with RDNA 3.0 architecture, while the NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip with Blackwell 2.0 architecture. The process nodes differ: 4 nm for AMD, 5 nm for NVIDIA, both from TSMC. Transistor counts are close, with the AMD part at 25,390 million and the NVIDIA part at 21,900 million, but the die sizes are nearly identical at 178 mm² and 181 mm² respectively.

Clock speeds show a notable split. The Ryzen Z1 Extreme GPU runs at an 800 MHz base and 2700 MHz boost, while the RTX 5070 Mobile runs at a 907 MHz base and 1425 MHz boost. Memory clocks differ substantially: the AMD part uses 800 MHz with 6.4 Gbps effective, while the NVIDIA part uses 1500 MHz with 24 Gbps effective. Memory configuration is also divergent: 16 GB LPDDR5 on a 64-bit bus for AMD, 8 GB GDDR7 on a 128-bit bus for NVIDIA, producing bandwidths of 51.20 GB/s and 384.0 GB/s respectively.

Compute unit counts are heavily in favor of NVIDIA: 4,608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and 144 tensor cores versus 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores for AMD. The AMD part has no tensor cores listed. Pixel rate favors AMD at 86.40 GPixel/s, but texture rate favors NVIDIA at 205.2 GTexel/s. FP32 and FP16 throughput both favor NVIDIA, with the AMD part’s FP16 being 2:1 versus NVIDIA’s 1:1. Power draw is 30 W for AMD and 50 W for NVIDIA. The AMD part has a 280 mm length, 111 mm height, and 21 mm width, while the NVIDIA part has no dimensions listed. Display outputs are a single USB Type-C for AMD and portable device dependent for NVIDIA. The bus interface is not listed for AMD, while NVIDIA uses PCIe 5.0 x16.

Architecture Differences

The architectural split is fundamental. The AMD Ryzen Z1 Extreme GPU uses RDNA 3.0 on the Phoenix chip, a 4 nm design with 25,390 million transistors packed into 178 mm². Its RDNA 3.0 architecture emphasizes efficiency at low power, with a 30 W TDP and a high boost clock of 2700 MHz to compensate for fewer execution units. The 12 RT cores provide ray tracing support, but the lack of tensor cores means no dedicated AI acceleration hardware. The 16 GB LPDDR5 memory is configured on a 64-bit bus, which is unusual for a GPU with 768 shading units, and the 51.20 GB/s bandwidth becomes the primary bottleneck for data-intensive workloads.

The NVIDIA GeForce RTX 5070 Mobile uses Blackwell 2.0 on the GB206 chip, a 5 nm design with 21,900 million transistors on 181 mm². Blackwell 2.0 is a more recent architecture designed for higher throughput per watt, though the 50 W TDP is still modest for a mobile part. The 4,608 shading units are arranged in a configuration that allows 13.13 TFLOPS of FP32, and the 144 tensor cores enable AI features like DLSS and other neural network workloads. The 36 RT cores provide ray tracing capability, and the 128-bit GDDR7 interface delivers 384.0 GB/s, which is 7.5x the AMD part’s bandwidth. The RTX 5070 Mobile’s FP16 throughput matches its FP32 at 13.13 TFLOPS, indicating a 1:1 ratio, whereas the AMD part’s FP16 is 2:1, meaning it uses half the rate for half-precision calculations.

The cache hierarchy is not fully detailed in the database, but the transistor density difference, 142.6M per mm² for AMD versus 121.0M per mm² for NVIDIA, suggests the AMD part packs more transistors into a slightly smaller die, likely for its integrated RDNA 3.0 blocks. The NVIDIA part’s larger die with fewer transistors indicates a different layout, possibly with more SRAM for its tensor cores and RT cores. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API coverage is identical.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Mobile wins in every category where measurable data exists. Its 13.13 TFLOPS FP32 and 13.13 TFLOPS FP16 make it the stronger choice for general compute, scientific simulation, and any workload that uses shader cores heavily. The 384.0 GB/s memory bandwidth is decisive for high-resolution textures, large framebuffers, and compute kernels that read and write substantial data. The 144 tensor cores give it a dedicated advantage in AI inference, deep learning, and any application that accelerates via tensor operations. The 36 RT cores provide more ray tracing throughput than the AMD part’s 12 RT cores, making it the better option for ray-traced games and rendering. Its 205.2 GTexel/s texture rate ensures that texture-heavy scenes, such as open-world environments or material-heavy renders, run without fill-rate stalls.

The AMD Ryzen Z1 Extreme GPU has specific wins that are narrower but real. Its 86.40 GPixel/s pixel rate exceeds the RTX 5070 Mobile’s 68.40 GPixel/s, so in purely fill-bound scenarios, such as simple 2D rendering or low-complexity scenes where pixel output is the limit, it can post higher throughput. Its 16 GB memory capacity is double that of the RTX 5070 Mobile, so for workloads that need to keep very large datasets resident in VRAM, such as certain machine learning models or multi-texture compositing, the AMD part can hold more data, though it will move that data more slowly. Its 30 W TDP is lower than the RTX 5070 Mobile’s 50 W, which makes it more suitable for power-constrained environments, and its 2700 MHz boost clock is the highest of the two, which contributes to its pixel rate advantage.

The RTX 5070 Mobile’s average benchmark score of 29,928 places it at 75th percentile, while the Ryzen Z1 Extreme GPU sits at 50th percentile with no recorded scores. The RTX 5070 Mobile’s nearest rivals, all within 1.7% of its score, are desktop GPUs from previous generations, confirming that it performs at a high desktop-class level in a mobile form factor. The Ryzen Z1 Extreme GPU has no nearest rivals listed, so its competitive position is undefined, but the zero benchmark average and lower percentile indicate it is not in the same performance tier. For users prioritizing compute performance, bandwidth, tensor acceleration, and ray tracing, the RTX 5070 Mobile is the only logical choice. For users prioritizing pixel fill, memory capacity, and power efficiency, the Ryzen Z1 Extreme GPU offers those specific advantages, but the overall performance gap remains substantial.
