AMD Radeon RX 5600 OEM vs NVIDIA RTX A1000 Mobile Comparison

The Verdict

The AMD Radeon RX 5600 OEM is the clear performance leader in every recorded benchmark, winning both head-to-head tests against the NVIDIA RTX A1000 Mobile. Its average benchmark score of 58085 places it 21.6% above the RTX A1000 Mobile's 47743, and it sits at the 87th percentile among all GPUs, versus the 85th percentile for the NVIDIA part. The RX 5600 OEM delivers a 28.2% advantage in Geekbench OpenCL and a 14.9% advantage in Geekbench Vulkan.

For users prioritizing raw compute throughput in a desktop context, the AMD Radeon RX 5600 OEM is the unequivocal choice. It offers substantially higher frame rates in compute-bound workloads, greater memory bandwidth, and a wider memory bus. The NVIDIA RTX A1000 Mobile, however, is built for a different environment entirely: it is an IGP (integrated graphics processor) with a 60 W TDP, designed for portable devices where power efficiency and thermal constraints dominate. The RX 5600 OEM, with its 125 W TDP and dual-slot cooler, requires a desktop power supply of 300 W and a dedicated 8-pin connector, making it unsuitable for mobile deployments.

The data suggests that the RX 5600 OEM is the pick for anyone building a desktop system with space and power headroom. The RTX A1000 Mobile is the pick for a laptop or compact mobile workstation where the absence of a discrete power connector and the low thermal envelope are non-negotiable. Neither card is currently in production, both being end-of-life products, but the RX 5600 OEM's performance lead is decisive in every measured category.

Where Each One Wins

The AMD Radeon RX 5600 OEM wins both recorded benchmarks, so there is no test in which the NVIDIA RTX A1000 Mobile emerges ahead. However, the two cards win in different contexts that go beyond raw scores.

The RX 5600 OEM wins in raw compute performance. Its Geekbench OpenCL score of 62427 is 28.2% higher than the RTX A1000 Mobile's 48703, and its Geekbench Vulkan score of 53743 is 14.9% higher than the NVIDIA card's 46782. The AMD card also has double the memory capacity (6 GB versus 4 GB), a 50% wider memory bus (192 bit versus 128 bit), and 63.6% more memory bandwidth (288.0 GB/s versus 176.0 GB/s). These are decisive advantages for any workload that saturates video memory or depends on high bandwidth, such as large textures, high-resolution rendering, or data-heavy compute tasks.

The RTX A1000 Mobile wins in deployment flexibility. It is an IGP with no power connectors, a 60 W TDP, and a PCIe 4.0 x8 interface, meaning it can be integrated into thin-and-light portable devices where the RX 5600 OEM's dual-slot cooler, 125 W TDP, and 1x 8-pin power connector would be impossible to accommodate. The NVIDIA card also supports DirectX 12 Ultimate (12_2), while the AMD card is limited to DirectX 12 (12_1), so the RTX A1000 Mobile has access to the full set of modern DirectX 12 features, including hardware ray tracing via its 16 RT cores and tensor acceleration via its 64 tensor cores. The RX 5600 OEM has no RT cores and no tensor cores, so any ray tracing or AI-accelerated workload will lack dedicated hardware support on the AMD side.

The architecture differences also favor the NVIDIA card in specific feature areas. The RTX A1000 Mobile uses the Ampere architecture on Samsung's 8 nm process, while the RX 5600 OEM uses RDNA 1.0 on TSMC's 7 nm node. The NVIDIA part has a higher transistor density (43.5M per mm² versus 41.0M per mm²) despite having fewer total transistors (8,700 million versus 10,300 million). This density advantage, combined with the dedicated RT and tensor cores, gives the RTX A1000 Mobile a feature set that the RX 5600 OEM simply lacks.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The AMD Radeon RX 5600 OEM is built on the RDNA 1.0 architecture, implemented on TSMC's 7 nm process with 10,300 million transistors on a 251 mm² die, yielding a transistor density of 41.0M per mm². The NVIDIA RTX A1000 Mobile uses the Ampere architecture, fabricated by Samsung on an 8 nm process, with 8,700 million transistors on a 200 mm² die, giving a slightly higher density of 43.5M per mm².

The most striking difference is in the compute pipelines. The RX 5600 OEM has 2048 shading units, 128 texture mapping units, and 64 render output units. The RTX A1000 Mobile also has 2048 shading units, but only 64 TMUs and 32 ROPs, exactly half the AMD card's counts. This disparity explains the massive differences in pixel rate and texture rate: the RX 5600 OEM achieves 99.84 GPixel/s and 199.7 GTexel/s, while the RTX A1000 Mobile manages only 36.48 GPixel/s and 72.96 GTexel/s. The AMD card is 2.7 times faster in pixel throughput and 2.7 times faster in texture throughput.

Clock speeds also differ dramatically. The RX 5600 OEM has a base clock of 1130 MHz, a boost clock of 1560 MHz, and a game clock of 1375 MHz. The RTX A1000 Mobile runs much lower, with a 630 MHz base and 1140 MHz boost. Even so, the NVIDIA card's FP32 throughput of 4.669 TFLOPS is respectable, but the RX 5600 OEM's 6.390 TFLOPS is 36.9% higher. In FP16, the gap widens further: the AMD card delivers 12.78 TFLOPS (2:1 ratio) versus the NVIDIA card's 4.669 TFLOPS (1:1 ratio), a 173.7% advantage for AMD in half-precision compute.

Memory architecture is another major divergence. The RX 5600 OEM uses 6 GB of GDDR6 on a 192-bit bus, with memory clocks at 1500 MHz (12 Gbps effective) yielding 288.0 GB/s of bandwidth. The RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, with memory at 1375 MHz (11 Gbps effective) for 176.0 GB/s. The AMD card's memory subsystem is 63.6% faster in bandwidth and has 50% more capacity.

The feature sets reflect their different generations. The RX 5600 OEM is from the Navi (RX 5000) generation, released on 2020-01-20, with DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The RTX A1000 Mobile is from the Ampere-MW (Ax000) generation, released on 2022-03-29, with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card adds 16 RT cores and 64 tensor cores, which the AMD card lacks entirely. The RTX A1000 Mobile also uses a PCIe 4.0 x8 interface versus the RX 5600 OEM's PCIe 4.0 x16, and its display outputs are portable-device dependent, whereas the AMD card offers 1x HDMI 2.0b and 3x DisplayPort 1.4a.

Head-to-Head Benchmarks

The recorded head-to-head data covers two Geekbench tests, and the AMD Radeon RX 5600 OEM wins both. There are no benchmark victories for the NVIDIA RTX A1000 Mobile in the database.

In Geekbench OpenCL, the AMD Radeon RX 5600 OEM scores 62427 against the NVIDIA RTX A1000 Mobile's 48703. This is a 28.2% delta in favor of AMD, the largest margin in any recorded test. This result aligns with the architectural differences: the RX 5600 OEM has twice the TMUs (128 versus 64), twice the ROPs (64 versus 32), and 63.6% more memory bandwidth. OpenCL workloads often stress memory throughput and pixel/texture operations, so the AMD card's advantages in those areas translate directly into a substantial score gap.

In Geekbench Vulkan, the AMD Radeon RX 5600 OEM scores 53743, while the NVIDIA RTX A1000 Mobile scores 46782. The delta is 14.9% in AMD's favor, a smaller but still decisive margin. Vulkan workloads can benefit from the NVIDIA card's dedicated RT and tensor cores in specific scenarios, but the raw compute and memory bandwidth advantages of the RX 5600 OEM are sufficient to maintain a clear lead.

Looking at the broader competitive landscape, the RX 5600 OEM's average score of 58085 places it just 0.3% below the Intel Arc A570M (58239) and 0.5% below the AMD Radeon RX 6950 XT (58392), while it sits 0.6% above the Intel Arc A580 (57756) and 0.8% above the NVIDIA P102-100 (58528). The RTX A1000 Mobile's average score of 47743 is 1.5% below the AMD Radeon RX 6800 XT (48477), 2.2% above the AMD Radeon RX 6550M (46702), 2.4% above the Intel Arc A530M (46614), and 2.5% above the AMD Radeon RX 5600M (46601). This context shows that the RX 5600 OEM competes with much higher-tier desktop GPUs, while the RTX A1000 Mobile sits in a lower performance tier, closer to mainstream mobile parts.

The wins breakdown is simple: the AMD Radeon RX 5600 OEM records 2 wins and 0 losses in the head-to-head tests. The NVIDIA RTX A1000 Mobile records 0 wins and 2 losses. In every measurable aspect of compute performance, from FP32 throughput to memory bandwidth to pixel rate, the AMD card is ahead. The only areas where the NVIDIA card holds an advantage are features that do not appear in these benchmark scores: hardware ray tracing, tensor acceleration, and a lower power envelope for mobile deployment. For a buyer focused purely on benchmark performance, the RX 5600 OEM is the superior product. For a buyer needing a low-power, connector-free GPU for a portable system, the RTX A1000 Mobile remains the only viable option of the two.
