Architecture Differences

The two GPUs share the RDNA 3.0 architecture but are implemented in very different contexts. The RX 7400 is a standalone discrete card built on the Navi 33 chip, while the Ryzen Z2 GPU is an integrated solution on the Hawk Point chip. Their process nodes differ: the RX 7400 uses TSMC 6 nm, while the Ryzen Z2 GPU uses TSMC 4 nm. The die sizes also contrast, with the RX 7400 at 204 mm² versus the Ryzen Z2 GPU at 178 mm², and transistor counts of 13,300 million versus 25,390 million respectively. This results in transistor density of 65.2M / mm² for the RX 7400 and 142.6M / mm² for the Ryzen Z2 GPU, reflecting the denser integration possible on the smaller node.

The compute resources are heavily skewed toward the discrete card. The RX 7400 has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The Ryzen Z2 GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. That is a 2.33x advantage in shading units, 2.33x in TMUs, 2x in ROPs, and 2.33x in ray tracing cores for the RX 7400. Neither part includes tensor cores.

Clock behavior also differs substantially. The RX 7400 has a base clock of 1452 MHz, a boost clock of 2300 MHz, and a game clock of 2200 MHz. The Ryzen Z2 GPU has a base clock of 800 MHz and a boost clock of 2700 MHz, with no game clock listed. The Ryzen Z2 GPU reaches a higher boost frequency by 400 MHz, but with far fewer execution units. Memory clocks diverge as well: the RX 7400 runs at 2250 MHz with 18 Gbps effective, while the Ryzen Z2 GPU runs at 937 MHz with 7.5 Gbps effective.

The memory subsystems are fundamentally different in type. The RX 7400 uses 8 GB GDDR6 with 288.0 GB/s bandwidth, while the Ryzen Z2 GPU uses 16 GB LPDDR5X with 119.9 GB/s. Both use a 128-bit bus, but the RX 7400 has 2.4x the bandwidth. The power envelope reflects this: the RX 7400 is rated at 43 W TDP and needs a 6-pin connector plus a 200 W suggested PSU, whereas the Ryzen Z2 GPU is rated at 28 W TDP with no connectors. The RX 7400 is dual-slot and uses PCIe 4.0 x8, while the Ryzen Z2 GPU lists no slot width, no bus interface, and a single USB Type-C display output. The RX 7400 offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 7400 and the Ryzen Z2 GPU. However, the RX 7400 has a full benchmark profile, while the Ryzen Z2 GPU has no recorded benchmark scores. The RX 7400 shows an average benchmark score of 2467, with a percentile rank of 17 among all GPUs. Its nearest rivals are the AMD Radeon 8040S with an average score of 2440 (1.1% lower), the NVIDIA GeForce 710M at 2433 (1.4% lower), the Intel HD Graphics 610 at 2425 (1.8% lower), and the NVIDIA GeForce GT 710M at 2422 (1.9% lower). These margins are small, placing the RX 7400 only slightly above low-end integrated and legacy mobile parts in the aggregate.

Breaking down the RX 7400 benchmark results, the highest score is in PassMark G3D at 11897, followed by PassMark G2D at 1209, and 3DMark Steel Nomad DX12 at 1103. Compute performance is moderate at 5152 in PassMark GPU Compute. API-specific results show 176 in PassMark DirectX 9, 97 in DirectX 11, 59 in DirectX 10, and 44 in DirectX 12. The Ryzen Z2 GPU has no equivalent entries, so no delta percentages can be calculated between the two parts. The recorded data indicates the RX 7400 is the only one of the two with measurable performance data, while the Ryzen Z2 GPU sits at an average benchmark score of 0 and a percentile of 50, the latter being a placeholder ranking without supporting scores.

The performance profile of the RX 7400, despite its higher raw specs, is modest in real-world aggregate terms. Its average score of 2467 places it at the 17th percentile, meaning the majority of GPUs in the database outperform it. The nearest rivals are all within 1.9% of its average score, which indicates that the RX 7400 does not separate itself meaningfully from those older or lower-tier parts in overall benchmark terms. Without any recorded scores for the Ryzen Z2 GPU, a direct performance comparison cannot be made from the data, but the architectural gap in shading units, texture units, ROPs, and memory bandwidth strongly favors the RX 7400 on paper.

The RX 7400 has no production status listed, while the Ryzen Z2 GPU is marked Active. Release dates are 2025-08-07 for the RX 7400 and 2024-12-31 for the Ryzen Z2 GPU. The RX 7400 lists a predecessor (Navi II) and successor (Navi IV); the Ryzen Z2 GPU lists neither. Neither part has a launch MSRP in the database.

Where Each One Wins

The RX 7400 wins on raw compute throughput. Its FP32 of 16.49 TFLOPS is double the 8.294 TFLOPS of the Ryzen Z2 GPU, and its FP16 of 32.97 TFLOPS is four times the 8.294 TFLOPS of the Ryzen Z2 GPU. It also wins decisively on memory bandwidth at 288.0 GB/s versus 119.9 GB/s, a 2.4x advantage. The RX 7400 has more shading units, TMUs, ROPs, and ray tracing cores, which translates to higher pixel rate (147.2 GPixel/s versus 86.40 GPixel/s) and texture rate (257.6 GTexel/s versus 129.6 GTexel/s). Its dual-slot design, HDMI 2.1a, and three DisplayPort 2.1 outputs make it a conventional discrete card for desktop output flexibility.

The Ryzen Z2 GPU wins on integration efficiency. It uses a 4 nm node with a 178 mm² die, smaller than the RX 7400's 204 mm², while packing 25,390 million transistors versus 13,300 million. It runs at a higher boost clock of 2700 MHz versus 2300 MHz. It has double the memory capacity at 16 GB versus 8 GB, albeit with lower bandwidth. Its 28 W TDP is lower than the 43 W TDP of the RX 7400, and it requires no power connectors, making it a low-power integrated option. The Ryzen Z2 GPU is marked Active in production status, while the RX 7400 has no status listed.

In benchmark terms, the RX 7400 is the only part with recorded scores. Its average of 2467 places it at the 17th percentile, with nearest rivals within 1.9%. The Ryzen Z2 GPU has no scores to compare. The RX 7400 is therefore the only one of the two with measurable performance data in the database.

The Verdict

The data separates these two parts into distinct roles. The AMD Radeon RX 7400 is a discrete desktop GPU with substantially higher compute resources, memory bandwidth, and pixel/texture throughput. Its benchmark profile, while modest at the 17th percentile, is at least recorded and comparable to nearby parts like the AMD Radeon 8040S and NVIDIA GeForce 710M. The AMD Ryzen Z2 GPU is a low-power integrated GPU with no benchmark scores, a 28 W TDP, no power connectors, and a single USB Type-C output. Its advantages are integration density, higher boost clock, larger memory capacity, and lower power draw.

For users prioritizing raw graphics throughput, the RX 7400 is the clear choice from the recorded specifications: double the FP32, 2.4x the memory bandwidth, and more than double the shading units, TMUs, ROPs, and ray tracing cores. For users prioritizing low power consumption, compact integration, and higher memory capacity, the Ryzen Z2 GPU fits that profile. The absence of any benchmark data for the Ryzen Z2 GPU means its real-world performance cannot be assessed from the database, whereas the RX 7400 has a complete set of scores. The verdict follows the data: the RX 7400 is the higher-performance part with measurable results, while the Ryzen Z2 GPU is an efficient, low-power integrated solution that trades compute for density and efficiency.
