AMD Radeon RX 7400 vs AMD Ryzen Z2 Go GPU Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for these two GPUs. The AMD Radeon RX 7400 has a full set of synthetic benchmark scores, while the AMD Ryzen Z2 Go GPU has no benchmark scores listed at all. This makes a direct comparison of measured performance impossible from the available data.

What can be analyzed is the RX 7400's position relative to its nearest rivals in the database. Its average benchmark score is 2467, which places it at the 17th percentile of all GPUs. The nearest competitors are the AMD Radeon 8040S with an average score of 2440, the NVIDIA GeForce 710M at 2433, the Intel HD Graphics 610 at 2425, and the NVIDIA GeForce GT 710M at 2422. The RX 7400 leads the closest rival, the 8040S, by 1.1%. Against the Intel HD Graphics 610 it is 1.8% ahead, and against the GeForce GT 710M it leads by 1.9%. These are narrow margins, indicating the RX 7400 sits in a performance tier where small differences separate adjacent products.

The RX 7400's individual benchmark results show its strongest showing in the PassMark G3D test with a score of 11897. DirectX 9 performance is also comparatively strong at 176, while DirectX 11 scores 97 and DirectX 10 scores 59. The DirectX 12 score is 44, and GPU compute performance is 5152. The 2D graphics score is 1209. The Steel Nomad DX12 test returns 1103.

The Ryzen Z2 Go GPU, by contrast, has no recorded benchmarks and no rival entries. Its average benchmark score is listed as zero, and its percentile is 50. The absence of data means the database cannot confirm any performance advantage for either part through direct testing.

Where Each One Wins

The RX 7400 wins decisively on raw compute throughput. Its FP32 performance of 16.49 TFLOPS is roughly four times the Ryzen Z2 Go GPU's 4.147 TFLOPS. Texture rate favors the RX 7400 at 257.6 GTexel/s versus 129.6 GTexel/s, and pixel rate is 147.2 GPixel/s versus 86.40 GPixel/s. The RX 7400 also has more of every execution resource: 1792 shading units versus 768, 112 TMUs versus 48, 64 ROPs versus 32, and 28 ray accelerators versus 12.

The Ryzen Z2 Go GPU wins on memory capacity, offering 16 GB compared to 8 GB. It also has a higher boost clock at 2700 MHz versus 2300 MHz, and a much lower thermal design power at 28 W versus 43 W. The Z2 Go uses no power connectors, while the RX 7400 requires a single 6-pin connector. The Z2 Go's suggested PSU requirement is not listed in the database, while the RX 7400 lists a 200 W suggested PSU.

Memory bandwidth tells the opposite story. The RX 7400's 288.0 GB/s is nearly three times the Z2 Go's 102.4 GB/s. The Z2 Go uses LPDDR5 memory at 6.4 Gbps effective, while the RX 7400 uses GDDR6 at 18 Gbps effective. For workloads that saturate memory bandwidth, the RX 7400 has a substantial advantage.

Specification Differences

The RX 7400 is a Radeon RX 7000 series part built on the Navi 33 chip with the codename Hotpink Bonefish. The Ryzen Z2 Go GPU is a Console GPU (AMD) generation part built on the Rembrandt+ chip. Both use a 6 nm process from TSMC, but the transistor counts differ slightly: 13,300 million for the RX 7400 versus 13,100 million for the Z2 Go. Die size is 204 mm² for the RX 7400 and 208 mm² for the Z2 Go. Transistor density is 65.2M per mm² for the RX 7400 and 63.0M per mm² for the Z2 Go.

Memory is a major differentiator. The RX 7400 has 8 GB GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. The Z2 Go has 16 GB LPDDR5 with a 128-bit bus and 102.4 GB/s bandwidth. The RX 7400's memory clock is 2250 MHz with 18 Gbps effective data rate, while the Z2 Go runs memory at 800 MHz with 6.4 Gbps effective.

Power and physical requirements differ. The RX 7400 has a TDP of 43 W, is dual-slot, uses one 6-pin power connector, and suggests a 200 W PSU. The Z2 Go has a TDP of 28 W, lists no power connectors, and has no suggested PSU figure. The RX 7400 uses a PCIe 4.0 x8 bus interface, while the Z2 Go's bus interface is not listed.

Display outputs differ. The RX 7400 provides 1x HDMI 2.1a and 3x DisplayPort 2.1. The Z2 Go provides a single USB Type-C output. The RX 7400's release date is 2025-08-07, while the Z2 Go's release date is 2024-12-31. The Z2 Go's production status is listed as Active, while the RX 7400's production status is not listed.

Architecture Differences

The RX 7400 uses RDNA 3.0 architecture, while the Ryzen Z2 Go GPU uses RDNA 2.0. This is a full generation gap in AMD's graphics architecture lineage. The RX 7400 belongs to the Navi III (RX 7000) generation and lists Navi II as its predecessor and Navi IV as its successor. The Z2 Go is categorized under Console GPU (AMD) generation with no predecessor or successor listed.

The compute resource allocation reflects the architectural and positioning differences. The RX 7400 has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray accelerators. The Z2 Go has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray accelerators. The RX 7400's FP16 performance is 32.97 TFLOPS at a 2:1 ratio, while the Z2 Go's FP16 is 8.294 TFLOPS at the same ratio.

Both GPUs support identical API feature sets: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither lists tensor cores. The RX 7400's display output suite is designed for conventional desktop monitor connections, while the Z2 Go's single USB Type-C output suggests an integrated or handheld-oriented design. The Z2 Go's lack of power connectors and lower TDP point to a power-constrained environment, while the RX 7400's 6-pin connector and 200 W suggested PSU indicate a desktop add-in card.

The Verdict

The data supports a clear split by use case rather than a single winner. The RX 7400 is the stronger compute part by every measured throughput metric in the database. Its FP32 performance of 16.49 TFLOPS, texture rate of 257.6 GTexel/s, and pixel rate of 147.2 GPixel/s place it well above the Z2 Go. Its 28 ray accelerators versus 12 also suggest better ray tracing throughput, though no direct ray tracing benchmark is recorded.

The Ryzen Z2 Go GPU wins on memory capacity, power efficiency, and boost clock. Its 16 GB of LPDDR5 memory doubles the RX 7400's 8 GB, which matters for workloads with large working sets. Its 28 W TDP is 15 W lower than the RX 7400's 43 W, and it requires no power connector. Its 2700 MHz boost clock is 400 MHz higher than the RX 7400's 2300 MHz.

The RX 7400's 288.0 GB/s memory bandwidth is a decisive advantage over the Z2 Go's 102.4 GB/s. The database places the RX 7400 at the 17th percentile of all GPUs with an average score of 2467, while the Z2 Go has no measured scores. The RX 7400's narrow lead over its nearest rivals, all within 1.9%, indicates it sits in a tightly packed performance tier.

For a desktop system where compute throughput, memory bandwidth, and display connectivity matter, the RX 7400 is the clear choice from the recorded data. For a power-constrained or handheld design where 16 GB memory capacity and no external power connector are priorities, the Z2 Go has the advantage. The absence of Z2 Go benchmark data means its actual performance relative to the RX 7400 remains unmeasured in the database.
