AMD Radeon RX 560X vs NVIDIA RTX A4000 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the NVIDIA RTX A4000 Mobile and the AMD Radeon RX 560X. Across the two shared benchmark tests, the RTX A4000 Mobile wins both, with the largest margin appearing in the Geekbench OpenCL test. In that test, the RTX A4000 Mobile scores 97,178, while the RX 560X scores 17,020. This translates to a 471% delta, meaning the NVIDIA part is nearly six times faster in raw compute throughput as measured by OpenCL. The result is not close, and the magnitude of the difference suggests entirely different performance classes.

The second shared test, Geekbench Vulkan, narrows the gap somewhat but still leaves the AMD part far behind. The RTX A4000 Mobile records 73,002, while the RX 560X manages 20,231. The delta here is 260.8%, so the NVIDIA GPU is still over 3.6 times faster in Vulkan workloads. Both tests point in the same direction: the RTX A4000 Mobile holds an overwhelming advantage in general-purpose compute and graphics API performance. For context on where the RTX A4000 Mobile sits in the wider database, its average benchmark score is 21,213, and it lands in the 66th percentile of all GPUs. Its nearest rival by average score is the NVIDIA Quadro RTX 5000 at 21,629, which is 1.2% higher, while the AMD Radeon RX Vega M GL trails by 1.1%. The RX 560X, by comparison, has an average benchmark score of 18,626 and sits in the 62nd percentile. Its closest rival in the database is the AMD Radeon Pro 5700 XT at 18,685, a 0.3% difference. Even the NVIDIA GeForce RTX 2070 is just 0.9% above the RX 560X.

Looking at the delta values in the head-to-head tests, the RTX A4000 Mobile is 471% ahead of the RX 560X in OpenCL and 260.8% ahead in Vulkan. The database's nearestRival deltas for the RTX A4000 Mobile are all within 1.6% of its average score, confirming that the RX 560X is not a peer competitor. Rather, the RX 560X belongs to a cluster of cards grouped around the Radeon Pro 5700 XT and Tesla K80 class, while the RTX A4000 Mobile competes with the Quadro RTX 5000 and Radeon RX Vega M GL tier.

The per-test scores reinforce this separation. In Passmark DirectX 11, the RTX A4000 Mobile records 127 points, and in DirectX 12 it scores 66. The RX 560X lacks recorded Passmark results entirely, so no direct comparison is possible there. The RTX A4000 Mobile also has Passmark DirectX 10, DirectX 9, G2D, G3D, and GPU Compute scores of 105, 157, 585, 14,796, and 6,394, respectively. None of these numbers exist for the RX 560X in the pack. When comparing the two GPUs, it is clear the RTX A4000 Mobile leads in every shared metric available, which amounts to exactly two wins for the NVIDIA part and zero wins for AMD.

Where Each One Wins

The RTX A4000 Mobile wins in every recorded benchmark category that overlaps between the two cards. Specifically, it wins Geekbench OpenCL with a 471% delta, Geekbench Vulkan with a 260.8% delta, and it holds wins across its entire Passmark suite, though those tests have no RX 560X counterpart. If the RX 560X wins anywhere, it would have to be in scenarios not represented in the database, since the data shows no test where the AMD card outperforms the NVIDIA card is ahead. Use cases for the RTX A4000 Mobile naturally fall on the high-performance side of the spectrum. Its fp32 compute of 17.20 TFLOPS versus the RX 560X's 2.611 TFLOPS suggests heavy compute tasks lean entirely toward the NVIDIA part. Memory bandwidth further separates the two: the RTX A4000 Mobile delivers 384.0 GB/s over a 256 bit bus, while the RX 560X provides 112.0 GB/s over 128 bit. For memory-bound workloads, the NVIDIA card is ~3.4 times the bandwidth in raw numbers, a critical factor for large datasets.

The RX 560X, despite being far behind, does have attributes that could matter in constrained environments. It carries a TDP of 75 W, while the RTX A4000 Mobile is rated at 115 W. The RX 560X is also a dual-slot card with a 170 mm length, and it draws no external power connectors, plus it suggests a 250 W PSU. The RTX A4000 Mobile also has no power connectors, but its TDP is higher. The AMD card's PCIe 3.0 x8 interface is older than the RTX A4000 Mobile's PCIe 4.0 x16, but in systems limited to older PCIe generations, the RX 560X might slot in more easily. Still, with only 4 GB of GDDR5 memory versus 8 GB of GDDR6, and texture rate of 81.60 GTexel/s versus 268.8 GTexel/s, the RX 560X has no measured performance advantage anywhere in the database. Its best case is as a lower-power, smaller-footprint option, but even then, the RTX A4000 Mobile has a node advantage (8 nm versus 14 nm) and far higher density, 44.4M transistors per square millimeter versus 24.4M.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The RTX A4000 Mobile uses the GA104 chip on the Ampere architecture, built on an 8 nm process at Samsung. It integrates 17,400 million transistors on a 392 mm² die, resulting in a transistor density of 44.4M per mm². The RX 560X, meanwhile, uses the Polaris 21 chip on GCN 4.0, fabricated on a 14 nm process at GlobalFoundries. That chip holds 3,000 million transistors on a 123 mm² die, giving a density of 24.4M per mm². The NVIDIA part is not only newer but also packs over five times the transistor count.

Core counts differ substantially. The RTX A4000 Mobile has 5,120 shading units, 160 texture mapping units, and 80 ROPs. It also includes 40 ray tracing cores and 160 tensor cores, features the RX 560X lacks entirely. The RX 560X has 1,024 shading units, 64 TMUs, and 16 ROPs. That is a 5x difference in shading units, a 2.5x difference in TMUs, and a 5x difference in ROPs. Clock speeds are closer than the architecture gap might suggest: the RTX A4000 Mobile has a base clock of 1140 MHz and a boost of 1680 MHz, while the RX 560X runs at 1175 MHz base and 1275 MHz boost. The NVIDIA card boosts higher, but the main difference comes from the massive core count advantage.

Memory architecture also diverges. The RTX A4000 Mobile uses 8 GB of GDDR6 memory at 12 Gbps effective, across a 256 bit bus, achieving 384.0 GB/s of bandwidth. The RX 560X uses 4 GB of GDDR5 at 7 Gbps effective over 128 bit, yielding 112.0 GB/s. Pixel rate for the RTX A4000 Mobile reaches 134.4 GPixel/s, texture rate 268.8 GTexel/s, and fp32 compute 17.20 TFLOPS, with fp16 also at 17.20 TFLOPS (1:1.0). The RX 560X delivers 20.40 GPixel/s, 81.60 GTexel/s, and 2.611 TFLOPS fp32 and fp16. In every throughput metric, the RTX A4000 Mobile is ahead by multiples of 4 to 6 times. The RX 560X supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, but the RTX A4000 Mobile supports DirectX 12 Ultimate (12_2, which is a higher tier), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part's ray tracing hardware, RT cores count 40 and tensor cores 160, are absent on the AMD card. This makes the RX 0.0 RTX A4000 Mobile supports hardware-accelerated ray tracing and AI workloads, while the RX 560X does not.
