AMD Radeon RX 7400 vs AMD Ryzen Z2 A GPU Comparison

The Verdict

The recorded data presents a clear separation between these two AMD GPUs. The AMD Radeon RX 7400 is a discrete desktop graphics card built on the RDNA 3.0 architecture, while the AMD Ryzen Z2 A GPU is an integrated solution based on RDNA 2.0. The RX 7400 holds the decisive performance advantage in every measured category, delivering substantially higher raw compute, pixel throughput, and memory bandwidth. The Ryzen Z2 A GPU, by contrast, operates at a much lower power envelope and integrates 16 GB of LPDDR5 memory, which positions it for compact, power-sensitive systems rather than high-frame-rate desktop gaming.

The benchmark database shows the RX 7400 at the 17th percentile among all GPUs, with an average benchmark score of 2467. The Ryzen Z2 A GPU sits at the 50th percentile, but its average benchmark score is recorded as 0, with no individual benchmark entries available in the database. This makes direct numerical comparison impossible from recorded runs; the analysis must rely on architectural specifications and the known performance of the RX 7400's nearest rivals. The RX 7400's nearest rivals include the AMD Radeon 8040S (average score 2440, delta 1.1%), the NVIDIA GeForce 710M (2433, delta 1.4%), the Intel HD Graphics 610 (2425, delta 1.8%), and the NVIDIA GeForce GT 710M (2422, delta 1.9%). These deltas are narrow, indicating that the RX 7400 sits in a tightly clustered performance band around those integrated and entry-level discrete parts.

For users seeking a dedicated graphics card for gaming or general GPU compute, the RX 7400 is the clear choice from the data. For ultra-low-power handheld or embedded designs, the Ryzen Z2 A GPU's 15 W TDP and 16 GB memory configuration make it the only viable option, though its compute resources are far smaller. The data shows no benchmark wins for either part in head-to-head tests, as that field is empty, so the verdict rests entirely on specification differences and the RX 7400's recorded scores.

Where Each One Wins

The RX 7400 wins decisively in raw graphics throughput. Its FP32 compute is 16.49 TFLOPS versus 1.638 TFLOPS for the Ryzen Z2 A GPU, a factor of roughly ten. Pixel rate favors the RX 7400 at 147.2 GPixel/s against 25.60 GPixel/s. Texture rate is 257.6 GTexel/s versus 51.20 GTexel/s. Memory bandwidth is 288.0 GB/s on the RX 7400's GDDR6 interface, nearly three times the 102.4 GB/s of the Ryzen Z2 A GPU's LPDDR5. Shading units number 1792 versus 512, TMUs 112 versus 32, and ROPs 64 versus 16. Ray tracing cores are 28 versus 8. Every compute-oriented specification favors the RX 7400 by a wide margin.

The Ryzen Z2 A GPU wins in power efficiency and memory capacity. Its TDP is 15 W, compared to 43 W for the RX 7400. That lower power draw, combined with a 7 nm process node, makes it suitable for battery-powered or passively cooled systems. The Ryzen Z2 A GPU also offers 16 GB of LPDDR5 memory, double the 8 GB of GDDR6 on the RX 7400. For workloads that require larger memory pools, such as certain AI inference or data-parallel tasks, the Z2 A GPU's capacity advantage could matter, though its bandwidth is much lower. The Z2 A GPU has no dedicated power connectors and uses a single USB Type-C display output, indicating a highly integrated design. The RX 7400 requires a 1x 6-pin power connector and a 200 W suggested PSU, plus a PCIe 4.0 x8 bus interface.

The recorded data also shows the RX 7400's DirectX 12 Ultimate (12_2) support, OpenGL 4.6, and Vulkan 1.4 API compatibility, which the Ryzen Z2 A GPU shares exactly. Both parts support the same API set, so software compatibility is not a differentiator. The RX 7400's display outputs are 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Z2 A GPU offers only 1x USB Type-C, so multi-monitor setups are exclusively the RX 7400's domain.

Architecture Differences

The RX 7400 uses the Navi 33 chip with the RDNA 3.0 architecture, codenamed Hotpink Bonefish, part of the Navi III (RX 7000) generation. It is fabricated on a 6 nm process at TSMC, containing 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The Ryzen Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC, containing 2,400 million transistors on a 163 mm² die, for a density of 14.7M per mm². The RX 7400's process node is one generation newer, and its transistor density is over four times higher.

Clock behavior 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. Memory runs at 2250 MHz with 18 Gbps effective data rate. The Ryzen Z2 A GPU has a base clock of 1000 MHz and a boost clock of 1600 MHz. Memory runs at 800 MHz with 6.4 Gbps effective. The RX 7400's higher clocks, combined with its larger execution resources, explain its commanding compute lead.

Memory architecture diverges as well. The RX 7400 uses 8 GB of GDDR6 on a 128-bit bus, achieving 288.0 GB/s. The Ryzen Z2 A GPU uses 16 GB of LPDDR5 on a 128-bit bus, achieving 102.4 GB/s. Both use a 128-bit memory interface, but the GDDR6 implementation on the RX 7400 delivers nearly three times the bandwidth. The Z2 A GPU's LPDDR5 memory is likely shared with the system, a common design for integrated graphics, though the database does not explicitly state that.

The RX 7400 supports PCIe 4.0 x8, while the Z2 A GPU has no recorded bus interface. The RX 7400 is dual-slot with a 1x 6-pin power connector and a 200 W suggested PSU. The Z2 A GPU has no slot width, power connector, or PSU specification recorded. The RX 7400's release date is recorded as 2025-08-07, while the Z2 A GPU's release date is 2024-12-31. The Z2 A GPU's production status is Active; the RX 7400's production status is not recorded.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark entries between the RX 7400 and the Ryzen Z2 A GPU. The winsA and winsB fields are both 0. Consequently, the comparison must rely on the RX 7400's absolute benchmark scores and the architectural specifications of both parts.

The RX 7400's recorded benchmark results are as follows: 3DMark Steel Nomad DX12 scores 1103. PassMark DirectX 10 scores 59, DirectX 11 scores 97, DirectX 12 scores 44, and DirectX 9 scores 176. PassMark G2D scores 1209, G3D scores 11897, and GPU Compute scores 5152. The average benchmark score is 2467. These numbers place the RX 7400 at the 17th percentile among all GPUs in the database.

The Ryzen Z2 A GPU has no recorded benchmark scores. Its average benchmark score is 0, and its percentile is 50, but that percentile appears to reflect its position in the database rather than measured performance. Without benchmark entries, the data cannot quantify its performance relative to the RX 7400 or any other GPU.

The specification gap is the only quantifiable comparison. The RX 7400 delivers 16.49 TFLOPS FP32 versus 1.638 TFLOPS, a 10.1x advantage. Pixel rate is 147.2 GPixel/s versus 25.60 GPixel/s, a 5.75x advantage. Texture rate is 257.6 GTexel/s versus 51.20 GTexel/s, a 5.03x advantage. Memory bandwidth is 288.0 GB/s versus 102.4 GB/s, a 2.81x advantage. The RX 7400 also has 3.5x more shading units, 3.5x more TMUs, 4x more ROPs, and 3.5x more ray tracing cores.

The RX 7400's nearest rival comparisons provide additional context. Its average score of 2467 is 1.1% above the AMD Radeon 8040S (2440), 1.4% above the NVIDIA GeForce 710M (2433), 1.8% above the Intel HD Graphics 610 (2425), and 1.9% above the NVIDIA GeForce GT 710M (2422). These are narrow margins, indicating that the RX 7400 is not a high-flying performer in absolute terms; it sits at the low end of the GPU spectrum, though still ahead of several integrated and entry-level parts.

The Ryzen Z2 A GPU's 512 shading units at 1600 MHz boost, with 1.638 TFLOPS, places it well below the RX 7400. Its 102.4 GB/s bandwidth and 25.60 GPixel/s pixel rate are closer to integrated graphics territory. The Z2 A GPU's 16 GB memory capacity is the one specification where it exceeds the RX 7400, but the bandwidth deficit means that capacity is unlikely to translate into higher frame rates in most gaming workloads.

The data supports a straightforward conclusion: the RX 7400 is the faster GPU by every measurable compute and memory throughput metric. The Ryzen Z2 A GPU is the lower-power, higher-capacity option, suited to systems where 15 W power draw and 16 GB unified memory matter more than raw graphics performance.
