AMD Ryzen Z2 Go GPU vs NVIDIA GeForce RTX 4070 Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark entries for the AMD Ryzen Z2 Go GPU and the NVIDIA GeForce RTX 4070. Consequently, a direct per-test score comparison is not possible from recorded data. However, the aggregate metrics and the RTX 4070’s standalone benchmark results provide a clear basis for relative positioning.

The RTX 4070’s average benchmark score is 37,648, placing it in the 81st percentile of all GPUs in the database. Its nearest rivals in the database include the NVIDIA Tesla P4 (average score 37,628, a 0.1% delta), the AMD Radeon RX Vega 56 (average score 37,507, a 0.4% delta), the NVIDIA GeForce RTX 4080 Mobile (average score 38,135, a -1.3% delta), and the AMD Radeon PRO W6400 (average score 37,157, a 1.3% delta). This indicates the RTX 4070 sits in a tightly clustered performance band among these rivals, with all deltas within a 2.6 percentage point spread.

The AMD Ryzen Z2 Go GPU holds a 50th percentile ranking across all GPUs in the database, with an average benchmark score of 0. The RTX 4070’s percentile rank of 81 versus the Z2 Go’s 50 represents a substantial gap in overall standing. The Z2 Go has no recorded benchmark scores, meaning its performance profile cannot be quantified from direct test results, only inferred from its architecture and specifications.

In terms of raw compute output, the RTX 4070 delivers 29.15 TFLOPS of FP32 performance, while the Z2 Go delivers 4.147 TFLOPS. This is a factor of approximately 7.0 in favor of the RTX 4070. For FP16, the RTX 4070 provides 29.15 TFLOPS (at a 1:1 ratio), while the Z2 Go provides 8.294 TFLOPS (at a 2:1 ratio), a margin of roughly 3.5 times more FP16 throughput for the NVIDIA part.

Pixel and texture rates reinforce the same hierarchy. The RTX 4070 achieves 158.4 GPixel/s and 455.4 GTexel/s, compared to 86.40 GPixel/s and 129.6 GTexel/s for the Z2 Go. The RTX 4070 is about 83% ahead in pixel fill rate and roughly 3.5 times ahead in texture fill rate.

Where Each One Wins

The RTX 4070 wins decisively in every measurable compute and rendering category within the database. Its FP32 throughput of 29.15 TFLOPS dwarfs the Z2 Go’s 4.147 TFLOPS, meaning workloads that rely on single-precision floating point math, such as traditional rasterization, physics simulation, and general-purpose GPU compute, will see a large advantage on the NVIDIA part.

In ray tracing, the RTX 4070 carries 46 RT cores versus 12 RT cores on the Z2 Go. This architectural difference suggests a substantial lead in ray-traced workloads, though no specific ray-tracing benchmark scores are recorded in the database. The RTX 4070 also includes 184 tensor cores, which the Z2 Go lacks entirely, providing dedicated hardware for AI-accelerated tasks such as DLSS-style upscaling and inference, though again no direct benchmarks are present.

The Z2 Go’s wins are limited to power efficiency and integration characteristics. Its TDP is 28 W versus 200 W for the RTX 4070, a seven-fold difference in power draw. The Z2 Go requires no power connectors and has a single USB Type-C display output, while the RTX 4070 needs a 16-pin connector, a 550 W suggested PSU, and offers 1x HDMI 2.1 plus 3x DisplayPort 1.4a outputs. For compact, low-power systems, the Z2 Go is the only viable option among the two based on these figures.

Memory bandwidth is another clear win for the RTX 4070: 504.2 GB/s versus 102.4 GB/s. The RTX 4070’s 12 GB of GDDR6X on a 192-bit bus far exceeds the Z2 Go’s 16 GB of LPDDR5 on a 128-bit bus in throughput, though the Z2 Go has a larger capacity. This makes the Z2 Go better suited for workloads requiring more memory footprint, while the RTX 4070 excels where bandwidth is the bottleneck.

Architecture Differences

The two GPUs stem from entirely different design philosophies. The AMD Ryzen Z2 Go uses the Rembrandt+ chip, built on RDNA 2.0 architecture, fabricated on a 6 nm process at TSMC. The NVIDIA GeForce RTX 4070 uses the AD104 chip, based on Ada Lovelace architecture, manufactured on a 5 nm process at the same foundry.

Transistor counts differ dramatically: the Z2 Go integrates 13,100 million transistors on a 208 mm² die, yielding a density of 63.0 million transistors per mm². The RTX 4070 packs 35,800 million transistors onto a 294 mm² die, achieving 121.8 million transistors per mm². The RTX 4070’s density is nearly double that of the Z2 Go, reflecting the newer process node and more complex architecture.

The Z2 Go belongs to a console GPU generation, while the RTX 4070 is part of the GeForce 40 series. The Z2 Go’s release date is December 31, 2024, whereas the RTX 4070 launched on April 11, 2023, and is now marked as end-of-life, with the GeForce 50 series as its successor. The Z2 Go remains in active production.

Clock behavior differs notably. The Z2 Go has a base clock of 800 MHz and a boost clock of 2700 MHz, while the RTX 4070 runs at a base of 1920 MHz and a boost of 2475 MHz. Despite the Z2 Go’s higher peak boost, its far smaller shader count (768 versus 5888) limits overall throughput.

Memory subsystems are distinct: the Z2 Go uses 16 GB of LPDDR5 at 6.4 Gbps effective, while the RTX 4070 uses 12 GB of GDDR6X at 21 Gbps effective. The bus widths are 128-bit versus 192-bit, respectively, explaining the bandwidth gap.

The RTX 4070 has 184 texture mapping units and 64 render output units, compared to 48 TMUs and 32 ROPs on the Z2 Go. The RTX 4070’s 184 tensor cores have no counterpart on the Z2 Go. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The RTX 4070 is a dual-slot card measuring 240 mm in length, 110 mm in height, and 40 mm in width, with a PCIe 4.0 x16 interface. The Z2 Go has no listed dimensions or bus interface, and its display output is a single USB Type-C. The RTX 4070’s launch MSRP is 599 USD, while the Z2 Go has no listed MSRP.

The Verdict

The data shows an overwhelming compute advantage for the NVIDIA GeForce RTX 4070. Its FP32 output is approximately seven times higher, its texture rate is over three times higher, and its memory bandwidth is nearly five times higher. The RTX 4070’s 81st percentile ranking versus the Z2 Go’s 50th percentile, combined with the absence of any recorded benchmarks for the Z2 Go, makes the performance hierarchy unambiguous.

The RTX 4070 is the appropriate choice for any workload requiring substantial rasterization, ray tracing, or compute throughput. Its 46 RT cores and 184 tensor cores provide capabilities that the Z2 Go cannot match architecturally. The 12 GB GDDR6X memory, while smaller in capacity, offers bandwidth that the Z2 Go’s LPDDR5 cannot approach.

The AMD Ryzen Z2 Go GPU is suited only for scenarios where power consumption and physical footprint are the primary constraints. Its 28 W TDP, lack of power connectors, and single USB Type-C output indicate a design intended for ultra-compact or power-limited systems. Its 16 GB memory capacity is larger than the RTX 4070’s 12 GB, which could benefit certain memory-bound scenarios, but the bandwidth deficit of 102.4 GB/s versus 504.2 GB/s severely limits such workloads.

The RTX 4070 is end-of-life, while the Z2 Go is active, but production status does not alter the recorded performance data. The RTX 4070’s nearest rivals are all within a 1.3% delta of its average score, indicating it is a strong mid-to-high-end performer in the database’s context. The Z2 Go has no rival data to contextualize its position beyond the 50th percentile.

For users prioritizing raw performance, the RTX 4070 is the only defensible choice based on the numbers. For users prioritizing minimal power draw and a small footprint, the Z2 Go offers a functional, if far less capable, alternative.
