AMD Radeon RX 5600M vs NVIDIA RTX A1000 Mobile Comparison

NVIDIA RTX A1000 Mobile and AMD Radeon RX 5600M are both end-of-life mobile graphics solutions, but they target different workloads and performance brackets. The data shows a clear split: the AMD part leads in raw compute benchmarks, while the NVIDIA part offers a feature set that includes dedicated ray tracing and tensor hardware. The RTX A1000 Mobile sits at the 85th percentile of all GPUs, with an average benchmark score of 47,743, while the RX 5600M also sits at the 85th percentile with an average score of 46,601. The two parts are separated by a mere 2.5% in average aggregate performance, yet their architecture and memory subsystems tell very different stories.

Where Each One Wins

The AMD Radeon RX 5600M is the clear winner in the two head-to-head tests available, taking both the Geekbench OpenCL and Vulkan workloads. Its OpenCL score of 59,589 is 18.3% higher than the RTX A1000 Mobile’s 48,703, and its Vulkan score of 48,843 is 4.2% ahead of the NVIDIA part’s 46,782. This makes the RX 5600M the stronger choice for general-purpose compute tasks that leverage OpenCL or Vulkan, particularly those that can take advantage of its higher raw FP32 throughput and larger memory pool.

The NVIDIA RTX A1000 Mobile, despite losing both head-to-head matchups, has its own niche. It is the only one of the two with dedicated RT cores (16) and tensor cores (64), which means it is equipped for hardware-accelerated ray tracing and AI workloads like DLSS or similar inference tasks. The RX 5600M has no RT or tensor cores at all. In the nearest rivals list, the RTX A1000 Mobile sits just 1.5% below the AMD Radeon RX 6800 XT in average score, indicating that its compute performance is not far off from a much larger desktop-class part, despite its 60 W TDP versus the RX 5600M’s 150 W TDP.

For users who prioritize compute density per watt, the RTX A1000 Mobile is the more efficient option, but for pure performance in the tested APIs, the RX 5600M wins outright. The NVIDIA part also supports DirectX 12 Ultimate (12_2), while the AMD part is limited to DirectX 12 (12_1), which matters for games or applications that require the latest DXR or mesh shader features.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The RTX A1000 Mobile uses NVIDIA’s Ampere architecture, built on the GA107 chip at Samsung’s 8 nm process, with 8,700 million transistors on a 200 mm² die. The RX 5600M uses AMD’s RDNA 1.0 architecture, built on the Navi 10 chip at TSMC’s 7 nm process, with 10,300 million transistors on a 251 mm² die. The AMD chip has more transistors and a larger die, but the NVIDIA chip has a higher transistor density at 43.5 million per mm² versus 41.0 million per mm².

The memory subsystems differ significantly. The RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, yielding 176.0 GB/s of bandwidth. The RX 5600M has 6 GB of GDDR6 on a 192-bit bus, yielding 288.0 GB/s of bandwidth — a 63.6% advantage in raw memory bandwidth. The RX 5600M also has more shading units (2,304 vs. 2,048), more TMUs (144 vs. 64), and more ROPs (64 vs. 32). This translates to higher theoretical pixel and texture rates: 80.96 GPixel/s and 182.2 GTexel/s for the AMD part versus 36.48 GPixel/s and 72.96 GTexel/s for the NVIDIA part.

Clock speeds are also higher on the AMD part, with a base clock of 1035 MHz and boost of 1265 MHz, compared to the RTX A1000 Mobile’s 630 MHz base and 1140 MHz boost. The RX 5600M also has a defined game clock of 1190 MHz, which the NVIDIA part lacks. FP32 performance is 5.829 TFLOPS for the AMD part versus 4.669 TFLOPS for the NVIDIA part, while FP16 performance is 11.66 TFLOPS (at a 2:1 ratio) for AMD versus 4.669 TFLOPS (at a 1:1 ratio) for NVIDIA. The NVIDIA part is the only one with RT and tensor cores, giving it a feature advantage for ray tracing and AI workloads that the AMD part cannot match.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows the RX 5600M winning decisively with a score of 59,589 against the RTX A1000 Mobile’s 48,703, a delta of -18.3% from the perspective of the NVIDIA part. This is a substantial margin that aligns with the AMD part’s higher FP32 throughput and memory bandwidth. The RX 5600M’s 5.829 TFLOPS of FP32 performance and 288.0 GB/s of bandwidth give it a clear compute advantage in this workload, which is heavily dependent on raw shader and memory throughput.

The Geekbench Vulkan test is much closer. The RX 5600M wins with 48,843 against the RTX A1000 Mobile’s 46,782, a delta of only -4.2%. This narrower margin suggests that the NVIDIA part’s architecture is more efficient in Vulkan, possibly due to its lower power draw or better driver optimization, but the AMD part still comes out ahead. The RTX A1000 Mobile’s nearest rival, the AMD Radeon RX 6800 XT, has an average score of 48,477, which is just 1.5% higher than the NVIDIA part — indicating that the RTX A1000 Mobile is competitive with a much larger desktop GPU in aggregate benchmarks.

In the overall average benchmark score, the RTX A1000 Mobile leads with 47,743 versus the RX 5600M’s 46,601, a 2.5% difference. This is because the NVIDIA part has both an OpenCL and Vulkan score, while the RX 5600M’s average includes additional tests like 3DMark Steel Nomad (1,320) and Geekbench Metal (76,653), which may skew the aggregate. The RX 5600M’s nearest rival list includes the NVIDIA RTX A2000 (46,043) and RTX 5880 Ada Generation (45,972), both of which it edges out by 1.2-1.4%.
