AMD Radeon RX 5600 OEM vs NVIDIA RTX A4500 Comparison

Where Each One Wins

The benchmark data divides cleanly along workload type, with the NVIDIA RTX A4500 dominating both recorded tests. In the Geekbench OpenCL compute test, the RTX A4500 scores 141,837 against 62,427 for the AMD Radeon RX 5600 OEM, a 127.2% advantage. The margin widens further in Geekbench Vulkan, where the NVIDIA card reaches 129,980 versus 53,743, a 141.9% lead. These are not marginal victories; they represent more than double the raw performance in both API paths.

The AMD Radeon RX 5600 OEM does not win any of the recorded head-to-head benchmarks. Its competitive position rests entirely on efficiency and form factor rather than absolute performance. The RX 5600 OEM draws 125 W compared to 200 W for the RTX A4500, and it requires a 300 W power supply instead of 550 W. For workloads that are power-constrained or thermally limited, the AMD card holds an advantage in system-level integration, even though the performance gap is substantial.

The RTX A4500's wins are concentrated in compute-heavy and graphics-API tests. The Geekbench OpenCL result reflects general-purpose GPU compute, where the NVIDIA card's 23.65 TFLOPS FP32 throughput and 640.0 GB/s memory bandwidth provide a decisive edge. The Vulkan result similarly favors the RTX A4500, with its 56 RT cores and 224 tensor cores accelerating modern graphics and ray-tracing workloads that the RX 5600 OEM cannot handle, as it has no RT or tensor cores at all.

In practical terms, the RTX A4500 is the choice for professional visualization, AI inference, and compute offload. The RX 5600 OEM, while slower, fits into systems with smaller power budgets and lower thermal envelopes. Its 6 GB memory and 192-bit bus are adequate for lighter workloads, but the data shows no scenario in the recorded benchmarks where it outperforms the NVIDIA card.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The NVIDIA RTX A4500 uses the GA102 chip built on Samsung's 8 nm process, with 28,300 million transistors on a 628 mm² die. The AMD Radeon RX 5600 OEM uses the Navi 10 chip on TSMC's 7 nm node, with 10,300 million transistors on a 251 mm² die. The RTX A4500 packs 45.1 million transistors per square millimeter, slightly denser than the RX 5600 OEM's 41.0 million.

The NVIDIA part is built on the Ampere architecture, a workstation-generation design that includes dedicated RT cores (56 of them) and tensor cores (224). The AMD card uses RDNA 1.0, which has no RT cores and no tensor cores. This architectural split explains the RTX A4500's dominance in Vulkan, where ray tracing and tensor-accelerated features are increasingly common. The RX 5600 OEM relies on 2048 shading units, 128 TMUs, and 64 ROPs, while the RTX A4500 scales to 7168 shading units, 224 TMUs, and 96 ROPs.

Memory configurations differ sharply. The RTX A4500 carries 20 GB of GDDR6 on a 320-bit bus, delivering 640.0 GB/s of bandwidth. The RX 5600 OEM has 6 GB of GDDR6 on a 192-bit bus, for 288.0 GB/s. The NVIDIA card's memory clock runs at 2000 MHz with 16 Gbps effective, versus 1500 MHz and 12 Gbps effective on the AMD part. This 2.2x bandwidth advantage is critical for large datasets in professional workloads.

The process node difference is notable: 8 nm Samsung for NVIDIA versus 7 nm TSMC for AMD. Despite the older node, the RTX A4500 achieves higher clock speeds (boost 1650 MHz versus 1560 MHz) and far higher throughput. The FP32 rate is 23.65 TFLOPS for NVIDIA versus 6.390 TFLOPS for AMD. FP16 on the RTX A4500 is 23.65 TFLOPS at a 1:1 ratio, while the RX 5600 OEM offers 12.78 TFLOPS at 2:1, meaning the NVIDIA card's FP16 throughput is nearly double and does not sacrifice precision.

Both cards support PCIe 4.0 x16 and dual-slot designs with a single 8-pin power connector. Display outputs differ: the RTX A4500 has four DisplayPort 1.4a outputs, while the RX 5600 OEM has one HDMI 2.0b and three DisplayPort 1.4a. The NVIDIA card supports DirectX 12 Ultimate (12_2), while the AMD card is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the RTX A4500 scoring 141,837 against the RX 5600 OEM's 62,427. This 127.2% delta reflects the NVIDIA card's larger shader count (7168 versus 2048) and higher memory bandwidth (640.0 GB/s versus 288.0 GB/s). The OpenCL result is a pure compute measurement, and the RTX A4500's 23.65 TFLOPS FP32 throughput is 3.7 times the AMD card's 6.390 TFLOPS, which aligns with the observed score gap.

The Geekbench Vulkan test widens the gap even further. The RTX A4500 reaches 129,980, while the RX 5600 OEM scores 53,743, a 141.9% difference. Vulkan exercises graphics pipeline features including ray tracing and compute shaders. The RTX A4500's 56 RT cores and 224 tensor cores accelerate these paths directly, while the RX 5600 OEM has no such hardware. The texture rate also favors NVIDIA: 369.6 GTexel/s versus 199.7 GTexel/s, and the pixel rate is 158.4 GPixel/s versus 99.84 GPixel/s.

In the database's overall scoring, the RTX A4500 averages 91,671 across all benchmarks and sits in the 93rd percentile of all GPUs. The RX 5600 OEM averages 58,085 and sits in the 87th percentile. The RTX A4500's nearest rivals include the NVIDIA RTX A4500 Mobile (0.6% higher average score), the AMD Radeon Instinct MI60 (0.9% lower), the NVIDIA Quadro GP100 (4.8% higher), and the AMD Radeon PRO W7600 (5.2% higher). The RX 5600 OEM's nearest rivals are tightly clustered: the Intel Arc A570M is 0.3% higher, the AMD Radeon RX 6950 XT is 0.5% lower, the Intel Arc A580 is 0.6% lower, and the NVIDIA P102-100 is 0.8% lower.
