AMD Radeon RX 7400 OEM vs AMD Ryzen Z2 GPU Comparison

The Verdict

The AMD Radeon RX 7400 OEM and the AMD Ryzen Z2 GPU occupy distinct positions in the database despite sharing the RDNA 3.0 architecture. The RX 7400 OEM is a discrete, single-slot add-in card built on the Navi 33 chip, while the Ryzen Z2 GPU is an integrated graphics solution within the Hawk Point processor, designed for console-class mobile platforms. Benchmark results indicate both devices sit at the 50th percentile among all GPUs, with an average benchmark score of zero in the recorded data, meaning no direct performance measurements separate them in this database. The RX 7400 OEM targets users requiring a dedicated, low-profile desktop GPU with a 55 W TDP and a 6-pin power connector. The Ryzen Z2 GPU suits a power-constrained, embedded or handheld scenario, drawing only 28 W and requiring no external power connectors. Given the identical percentile ranking and absence of head-to-head scores, the data does not favor one as universally faster; instead, the choice hinges on integration flexibility versus standalone expandability.

Architecture Differences

Both GPUs use RDNA 3.0 architecture, but they diverge significantly in physical implementation. The RX 7400 OEM uses the Navi 33 chip fabricated on TSMC's 6 nm process, containing 13,300 million transistors across a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The Ryzen Z2 GPU uses the Hawk Point chip on a 4 nm process, packing 25,390 million transistors into a smaller 178 mm² die, achieving a much higher density of 142.6 million per square millimeter. The RDNA 3.0 generation code differs as well: the RX 7400 OEM belongs to the Navi III (RX 7000) generation and carries the codename Hotpink Bonefish, while the Ryzen Z2 GPU is classified under Console GPU (AMD) with no codename recorded.

The compute configuration favors the discrete card. The RX 7400 OEM delivers 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The Ryzen Z2 GPU provides only 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores. Despite the lower counts, the Ryzen Z2 GPU reaches a higher boost clock of 2700 MHz versus 1100 MHz on the RX 7400 OEM, and its base clock runs at 800 MHz compared to 330 MHz. The resulting FP32 throughput is 8.294 TFLOPS for the Ryzen Z2 GPU, slightly ahead of the RX 7400 OEM's 7.885 TFLOPS, with both offering 1:1 FP16 rates. Pixel fill rates show the Ryzen Z2 GPU at 86.40 GPixel/s versus 70.40 GPixel/s for the RX 7400 OEM, while texture rates are close at 129.6 GTexel/s and 123.2 GTexel/s, respectively.

Memory architecture differs fundamentally. The RX 7400 OEM uses 8 GB of GDDR6 on a 128-bit bus, achieving 172.8 GB/s bandwidth with a memory clock of 1350 MHz (10.8 Gbps effective). The Ryzen Z2 GPU uses 16 GB of LPDDR5X on the same 128-bit bus, but bandwidth drops to 119.9 GB/s due to a lower memory clock of 937 MHz (7.5 Gbps effective). The RX 7400 OEM connects via PCIe 4.0 x8, while the Ryzen Z2 GPU lists no bus interface, consistent with an integrated design. Display outputs also differ: the RX 7400 OEM offers 1x HDMI 2.1a and 3x DisplayPort 2.1, whereas the Ryzen Z2 GPU provides a single USB Type-C output. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7400 OEM measures 167 mm in length and is single-slot, while the Ryzen Z2 GPU has no recorded dimensions, slot width, or power connectors.

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Radeon RX 7400 OEM versus the AMD Ryzen Z2 GPU. With zero wins recorded for either side and no benchmark scores populated, the comparison relies entirely on architectural and specification data. The closest analytical proxies come from the theoretical throughput figures, which reveal a nuanced picture. The Ryzen Z2 GPU leads in FP32 compute with 8.294 TFLOPS, a 5.2% advantage over the RX 7400 OEM's 7.885 TFLOPS. This result appears counterintuitive given the RX 7400 OEM's 1792 shading units versus 768, but the Ryzen Z2 GPU's 2700 MHz boost clock compensates substantially. Similarly, the Ryzen Z2 GPU achieves a higher pixel rate of 86.40 GPixel/s against 70.40 GPixel/s, a 22.7% margin, and a slightly higher texture rate of 129.6 GTexel/s versus 123.2 GTexel/s, a 5.2% edge.

The RX 7400 OEM counters with decisive memory bandwidth superiority. Its 172.8 GB/s exceeds the Ryzen Z2 GPU's 119.9 GB/s by 44.1%, which directly impacts fill-rate-bound scenarios and high-resolution texture streaming. The GDDR6 memory operates at 10.8 Gbps effective, compared to 7.5 Gbps for LPDDR5X, and the RX 7400 OEM's 8 GB capacity, while half the Ryzen Z2 GPU's 16 GB, still provides adequate headroom for 1080p workloads. The RX 7400 OEM also offers more ray tracing hardware with 28 RT cores versus 12, which could improve RT workload scaling despite the lower clock speeds.

Process technology favors the Ryzen Z2 GPU, with a 4 nm node versus 6 nm, resulting in a transistor density of 142.6M per mm² versus 65.2M per mm². The Ryzen Z2 GPU's 25,390 million transistors, nearly double the RX 7400 OEM's count, enable the larger memory interface and integrated design within a 28 W envelope. The RX 7400 OEM's 55 W TDP, while higher, remains modest for a discrete card and aligns with its single-slot form factor and 250 W suggested power supply.

Release timing shows the Ryzen Z2 GPU entering the database earlier on 2024-12-31, with the RX 7400 OEM following on 2025-08-07. The Ryzen Z2 GPU carries an active production status, while the RX 7400 OEM lists none. Both GPUs share identical API support, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which means software compatibility does not differentiate them in the recorded data.

The absence of real-world benchmark scores limits the analysis to theoretical specifications. The Ryzen Z2 GPU's compute and fill rate advantages suggest it may handle shader-heavy and pixel-dense workloads efficiently, while the RX 7400 OEM's memory bandwidth and larger ROP count (64 versus 32) point toward better performance in bandwidth-limited scenarios. The RX 7400 OEM's 128-bit bus paired with faster GDDR6 memory provides a clear bandwidth advantage, but the Ryzen Z2 GPU's 16 GB capacity offers double the frame buffer for large assets or multitasking. Neither device has recorded wins in the head-to-head table, and both hold identical percentile rankings, indicating the database treats them as comparable in overall standing despite their divergent designs.
