AMD Radeon RX 460 vs NVIDIA GeForce RTX 2070 SUPER Comparison

Head-to-Head Benchmarks

The recorded data provides two direct comparison points between the NVIDIA GeForce RTX 2070 SUPER and the AMD Radeon RX 460, and the results are decisively one-sided. In Geekbench OpenCL, the RTX 2070 SUPER scores 83,358 against the RX 460's 17,855, a 366.9% advantage. That is not a marginal gap; it places the newer card in an entirely different performance tier. The RTX 2070 SUPER is roughly 4.7 times faster in raw compute throughput, which aligns with the massive disparity in shading units (2,560 versus 896) and FP32 output (9.062 TFLOPS versus 2.150 TFLOPS).

The second head-to-head test, Geekbench Vulkan, tells the same story with a slightly smaller but still enormous delta. The RTX 2070 SUPER posts 90,637, while the RX 460 manages 20,198. That is a 348.7% lead for the NVIDIA part. Vulkan is a lower-level API that often narrows gaps between older and newer architectures, yet here the difference remains overwhelming. The RX 460's GCN 4.0 design, with its 128-bit memory bus and 112.0 GB/s bandwidth, simply cannot feed the workload at the same rate as the 256-bit, 448.0 GB/s setup on the RTX 2070 SUPER.

It is worth remembering the RX 460 has a third benchmark result in the database, Geekbench Metal (17,065), but there is no corresponding score for the RTX 2070 SUPER in that test, so it cannot be used for a direct comparison. The two available head-to-head tests both go to the NVIDIA card, with zero wins for the AMD part. The average benchmark score gap reinforces this: the RTX 2070 SUPER sits at 20,282, while the RX 460 sits at 18,373. That 1,909-point difference is modest relative to the individual test deltas because the averages include different test suites, but the direction is consistent.

Looking at the nearest rivals for context, the RTX 2070 SUPER's average score places it just 1% behind the NVIDIA Quadro M4000M (20,480) and 1.2% behind the RTX 3070 Mobile (20,534). It is also within 1.5% of the Intel Arc A750 (20,582). This suggests the RTX 2070 SUPER, despite being an older end-of-life product, still holds its own against mid-range mobile and desktop parts from later generations. The RX 460, meanwhile, sits within 0.1% of the Intel Arc A770M (18,383) and 0.9% of the AMD FirePro D500 (18,533), indicating it is roughly comparable to older workstation-class GPUs, not modern gaming hardware.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 2070 SUPER is the superior GPU in every measurable way. For anyone choosing between these two, the RTX 2070 SUPER wins on raw compute, memory bandwidth, and API feature support. The RX 460 was designed for a different era and a different purpose, and the benchmark results reflect that. However, the verdict is not purely about speed, it is about context. The RTX 2070 SUPER carries a launch MSRP of 499 USD, while the RX 460 has no recorded launch price, which means the latter was likely positioned as a budget-oriented card. The database shows that the RTX 2070 SUPER is 366.9% faster in OpenCL and 348.7% faster in Vulkan, so if raw performance is the sole criterion, the choice is obvious.

But the RX 460 has one significant advantage that the benchmark scores do not capture: its power envelope. The RTX 2070 SUPER draws 215 W and requires a 550 W PSU plus a 6-pin and 8-pin connector. The RX 460 draws only 75 W, requires no external power connectors, and works with a 250 W PSU. For a system with a weak power supply or a small form factor case, the RX 460 is far easier to integrate. The RTX 2070 SUPER measures 267 mm in length, while the RX 460 measures 170 mm, a difference that could matter in compact builds. If the goal is maximum compute, pick the RTX 2070 SUPER. If the goal is a low-power, low-footprint card for basic tasks, the RX 460 remains functional, but the data shows it is outclassed by a wide margin.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The RTX 2070 SUPER uses the Turing architecture on a 12 nm TSMC process, with the TU104 chip containing 13,600 million transistors on a 545 mm² die. The RX 460 uses GCN 4.0 on a 14 nm GlobalFoundries process, with the Baffin chip containing 3,000 million transistors on a 123 mm² die. The transistor density is nearly identical, 25.0M per mm² for the NVIDIA part versus 24.4M per mm² for the AMD part, but the absolute transistor count is over four times higher on the RTX 2070 SUPER.

The memory subsystems are fundamentally different. The RTX 2070 SUPER has 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s of bandwidth, while the RX 460 has 2 GB of GDDR5 on a 128-bit bus, delivering 112.0 GB/s. That is a fourfold difference in both capacity and bandwidth, which directly impacts texture-heavy workloads and high-resolution rendering. The RTX 2070 SUPER also features dedicated ray tracing cores (40) and tensor cores (320), neither of which exists on the RX 460. The NVIDIA card supports DirectX 12 Ultimate (12_2), while the AMD card is limited to DirectX 12 (12_0). Both support OpenGL 4.6, but the Vulkan versions differ: the RTX 2070 SUPER supports 1.4, while the RX 460 supports 1.3.

The bus interface also differs, with the RTX 2070 SUPER using PCIe 3.0 x16 and the RX 460 using PCIe 3.0 x8. This halves the available bandwidth for data transfers between the GPU and the host system, which can matter in CPU-bound scenarios. The display outputs are similar in spirit but not in count: the RTX 2070 SUPER offers 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C, while the RX 460 offers 1x DVI, 1x HDMI 2.0b, and 1x DisplayPort 1.4a. The RTX 2070 SUPER's USB Type-C output is a notable addition for modern monitors and VR headsets.

Where Each One Wins

The RTX 2070 SUPER wins in every head-to-head benchmark recorded, so the use-case split is less about performance and more about system constraints. In compute-heavy tasks like OpenCL or Vulkan workloads, the RTX 2070 SUPER is the clear choice. The 366.9% lead in OpenCL means it can handle machine learning inference, video encoding, and GPU-accelerated rendering far more effectively. The 448.0 GB/s bandwidth and 8 GB frame buffer also make it suitable for 4K textures and multi-monitor setups, where the RX 460's 112.0 GB/s and 2 GB would quickly become a bottleneck.

The RX 460 wins in scenarios where power draw and physical size are the limiting factors. Its 75 W TDP, no external power connector requirement, and 170 mm length make it ideal for legacy office PCs, small form factor builds, or systems with a 250 W PSU. It can drive basic display output and light 2D workloads without stressing the power delivery. The RTX 2070 SUPER, at 267 mm and 215 W, demands a more robust platform. For users with a modern gaming rig that can feed a 550 W PSU and accommodate a dual-slot card, the RTX 2070 SUPER is the only rational choice from the data. For users with a constrained chassis and a limited power budget, the RX 460 is the only option that fits, even if its compute output is drastically lower.
