AMD Radeon RX 5600 OEM vs NVIDIA GeForce RTX 3080 Ti Comparison

AMD Radeon RX 5600 OEM and NVIDIA GeForce RTX 3080 Ti sit at opposite ends of the performance spectrum, with the recorded data showing a decisive split between the two. The RX 5600 OEM, an end-of-life RDNA 1.0 part from the RX 5000 series, delivers a modest average benchmark score of 58,085 and sits in the 87th percentile of all GPUs. The RTX 3080 Ti, an end-of-life Ampere flagship from the GeForce 30-series, posts a lower average score of 41,187 due to a heavier weighting of legacy DirectX tests, yet it holds the 83rd percentile. The head-to-head results, however, tell a far clearer story: the RTX 3080 Ti wins both recorded comparisons by massive margins, making it the unambiguous choice for raw compute and modern API workloads, while the RX 5600 OEM remains a lighter, lower-power alternative with a smaller footprint in the database.

Where Each One Wins

The use-case split is stark when looking at the head-to-head data. The NVIDIA GeForce RTX 3080 Ti dominates both recorded benchmark categories, winning 100% of the head-to-head comparisons. In OpenCL compute, it scores 170,037 against the AMD Radeon RX 5600 OEM's 62,427, a delta of -63.3% for the AMD card. In Vulkan, the gap widens further: the RTX 3080 Ti scores 192,697 versus 53,743, a delta of -72.1%. For any workload that leans on Vulkan or OpenCL, the RTX 3080 Ti is the only rational pick from the data.

The RX 5600 OEM does not win a single head-to-head test, but its profile suggests a different role. With a 125 W TDP, a single 8-pin power connector, and a suggested PSU of 300 W, it is far less demanding than the RTX 3080 Ti's 350 W TDP, 1x 12-pin connector, and 750 W suggested PSU. The RX 5600 OEM also carries a much smaller die: 251 mm² versus 628 mm², and far fewer transistors at 10,300 million versus 28,300 million. For systems where power delivery and physical space are constrained, the AMD card is the more practical fit, even if its benchmark scores are lower.

The average benchmark scores in the database add nuance. The RX 5600 OEM averages 58,085, which places it just 0.3% behind the Intel Arc A570M (58,239) and 0.5% behind the AMD Radeon RX 6950 XT (58,392). It is 0.6% ahead of the Intel Arc A580 (57,756) and 0.8% behind the NVIDIA P102-100 (58,528). The RTX 3080 Ti averages 41,187, which is 0.8% ahead of the AMD Radeon Pro 5300 (40,870) and 2% ahead of the NVIDIA GeForce RTX 5070 (40,377), but 1.2% behind the NVIDIA Tesla M40 24 GB (41,707) and 1.7% behind the NVIDIA Tesla M40 (41,897). The RTX 3080 Ti's average is dragged down by its PassMark legacy scores, which are very low (184 in DirectX 10, 223 in DirectX 11, 110 in DirectX 12, 274 in DirectX 9), while its PassMark G3D score of 26,896 and GPU compute score of 15,282 show strong modern performance.

Architecture Differences

The architectural gap between these two GPUs is generational and fundamental. The AMD Radeon RX 5600 OEM uses the Navi 10 chip built on RDNA 1.0 architecture, fabricated by TSMC on a 7 nm process. It packs 10,300 million transistors into a 251 mm² die, yielding a transistor density of 41.0M per mm². The NVIDIA GeForce RTX 3080 Ti uses the GA102 chip built on Ampere architecture, fabricated by Samsung on an 8 nm process. It houses 28,300 million transistors in a 628 mm² die, with a transistor density of 45.1M per mm². The RTX 3080 Ti is both physically larger and denser, giving it a massive resource advantage.

Memory configurations diverge sharply. The RX 5600 OEM has 6 GB of GDDR6 on a 192-bit bus, delivering 288.0 GB/s of bandwidth with memory clocked at 1500 MHz (12 Gbps effective). The RTX 3080 Ti has 12 GB of GDDR6X on a 384-bit bus, delivering 912.4 GB/s of bandwidth with memory clocked at 1188 MHz (19 Gbps effective). That is more than triple the bandwidth, a critical factor for high-resolution textures and compute workloads.

Compute resources are equally lopsided. The RX 5600 OEM has 2048 shading units, 128 TMUs, and 64 ROPs, with no ray tracing cores or tensor cores. Its FP32 throughput is 6.390 TFLOPS, and FP16 is 12.78 TFLOPS at a 2:1 ratio. The RTX 3080 Ti has 10,240 shading units, 320 TMUs, and 112 ROPs, plus 80 ray tracing cores and 320 tensor cores. Its FP32 throughput is 34.10 TFLOPS, and FP16 is also 34.10 TFLOPS at a 1:1 ratio. The RTX 3080 Ti is over five times faster in FP32 and offers dedicated hardware for ray tracing and AI workloads, features the RX 5600 OEM lacks entirely.

Clock speeds and API support also differ. The RX 5600 OEM runs at a 1130 MHz base and 1560 MHz boost, with a game clock of 1375 MHz. The RTX 3080 Ti runs at a 1365 MHz base and 1665 MHz boost. Both support PCIe 4.0 x16, but the RTX 3080 Ti supports DirectX 12 Ultimate (12_2) while the RX 5600 OEM is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX 3080 Ti also supports HDMI 2.1, while the RX 5600 OEM is limited to HDMI 2.0b. The RTX 3080 Ti measures 285 mm in length, 112 mm in height, and 40 mm in width; the RX 5600 OEM has no recorded dimensions in the database.

Head-to-Head Benchmarks

The head-to-head results are one-sided. In Geekbench OpenCL, the RTX 3080 Ti scores 170,037 against the RX 5600 OEM's 62,427. That is a 63.3% deficit for the AMD card, meaning the NVIDIA GPU delivers roughly 2.7 times the OpenCL compute performance. In Geekbench Vulkan, the RTX 3080 Ti scores 192,697 against 53,743, a 72.1% deficit for the AMD card, or about 3.6 times the Vulkan performance. These are not marginal wins; they are category-level differences.

The RX 5600 OEM's best showing in the database is its Geekbench OpenCL score of 62,427, which is higher than its Vulkan score of 53,743. The RTX 3080 Ti, by contrast, scores higher in Vulkan (192,697) than in OpenCL (170,037), indicating a stronger scaling path in the newer API. The RTX 3080 Ti's PassMark results reinforce its modern performance: 26,896 in G3D and 15,282 in GPU compute, with low legacy scores (184 in DirectX 10, 223 in DirectX 11, 110 in DirectX 12, 274 in DirectX 9, and 1,091 in G2D). The RX 5600 OEM has no PassMark records in the database, so its legacy API performance is unmeasured.

The average benchmark scores place the RX 5600 OEM in a cluster with mid-range cards, while the RTX 3080 Ti sits near older professional cards. The RX 5600 OEM is 0.3% behind the Intel Arc A570M and 0.5% behind the AMD Radeon RX 6950 XT, yet 0.6% ahead of the Intel Arc A580. The RTX 3080 Ti is 0.8% ahead of the AMD Radeon Pro 5300 and 2% ahead of the NVIDIA GeForce RTX 5070, but 1.2% behind the NVIDIA Tesla M40 24 GB and 1.7% behind the NVIDIA Tesla M40. These rival deltas show that the RTX 3080 Ti's average is not representative of its head-to-head dominance; the legacy PassMark tests skew its aggregate score downward.

The Verdict

The data points to a clear choice for compute-heavy and modern API workloads: the NVIDIA GeForce RTX 3080 Ti. Its head-to-head wins in both OpenCL and Vulkan are overwhelming, with deltas of -63.3% and -72.1% against the RX 5600 OEM. Its 34.10 TFLOPS FP32 throughput, 912.4 GB/s memory bandwidth, and dedicated ray tracing and tensor cores make it the superior option for any task that can use those resources. The RTX 3080 Ti also carries a launch MSRP of 1,199 USD, a figure the database records, though the comparison here is purely on performance.

The AMD Radeon RX 5600 OEM is the choice only when constraints matter more than score. Its 125 W TDP, 300 W suggested PSU, and single 8-pin connector make it far easier to integrate into modest systems. Its 6 GB of GDDR6 memory and 288.0 GB/s bandwidth are sufficient for lighter workloads, and its 87th percentile ranking shows it is not a weak card in absolute terms. But it loses every recorded head-to-head test, and its lack of ray tracing and tensor cores limits its feature set.

For a user prioritizing raw compute, modern API performance, and memory bandwidth, the RTX 3080 Ti is the only defensible pick from the recorded data. For a user with strict power or physical constraints, the RX 5600 OEM offers a functional, less demanding alternative, though the benchmark gap is too large to ignore. The database records no scenario where the RX 5600 OEM outperforms the RTX 3080 Ti.
