AMD Radeon RX 6400 vs NVIDIA GeForce GTX 760M Comparison

The Verdict

The data places the AMD Radeon RX 6400 and NVIDIA GeForce GTX 760M in different performance tiers entirely. The RX 6400 holds a 471.2% lead in Geekbench OpenCL and a 236.3% lead in Geekbench Vulkan over the GTX 760M. The average benchmark score of 6001 for the RX 6400 versus 5236 for the GTX 760M reflects a roughly 14.6% overall gap based on the recorded averages. The RX 6400 sits at the 35th percentile of all GPUs, while the GTX 760M sits at the 31st percentile, placing both in the lower half of the database but with the AMD part clearly ahead.

For buyers today, the RX 6400 is the only sensible choice for any modern workload involving compute or graphics APIs. Its 12 RT cores and DirectX 12 Ultimate support make it usable for current-generation gaming features, whereas the GTX 760M lacks hardware ray tracing entirely. The GTX 760M belongs to a 2013-era mobile platform, and its benchmark results show it cannot compete in any measured category. The RX 6400 is end-of-life as well, but its newer architecture and superior raw scores make it the pick for anyone needing a low-profile, single-slot desktop card with PCIe 4.0 connectivity. The GTX 760M is only relevant for legacy system identification or historical comparison.

Where Each One Wins

The RX 6400 wins every recorded head-to-head benchmark. In Geekbench OpenCL, it scores 32011 versus 5604 for the GTX 760M, a 471.2% advantage. In Geekbench Vulkan, it scores 16372 versus 4868, a 236.3% advantage. These are not close contests; the AMD card dominates in both compute and graphics API workloads.

The GTX 760M has no benchmark wins in the database. Its only recorded scores are the two Geekbench entries, and it loses both. However, the GTX 760M does have one structural advantage: its 128-bit memory bus versus the RX 6400's 64-bit bus, and its MXM module form factor, which was designed for notebook use. For desktop users, the RX 6400's PCIe 4.0 x4 interface and single-slot design are more relevant. For mobile users, the GTX 760M is the only one of the two that was ever intended for portable systems, though the RX 6400 can still function in small form factor desktops due to its lack of power connectors.

Architecture Differences

The architectural gap between these two GPUs spans nearly a decade of development. The RX 6400 uses the Navi 24 chip built on RDNA 2.0 architecture, fabricated on a 6 nm process at TSMC. It contains 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5 million per square millimeter. The GTX 760M uses the GK106S chip based on Kepler architecture, built on a 28 nm process, also at TSMC. It packs 2,540 million transistors onto a much larger 221 mm² die, giving a transistor density of just 11.5 million per square millimeter. The density difference is stark: the RX 6400 crams over four times as many transistors per area, which explains how it achieves far higher performance from a smaller physical package.

Clock speeds reinforce the generational divide. The RX 6400 runs at a 1923 MHz base and 2321 MHz boost, with a game clock of 2039 MHz. The GTX 760M runs at a 628 MHz base and 719 MHz boost. Even accounting for architectural differences, the RX 6400 operates at over three times the clock frequency. Memory clocks differ similarly: the RX 6400 uses 2000 MHz memory with 16 Gbps effective speed, while the GTX 760M uses 1002 MHz memory at 4 Gbps effective.

The memory subsystems diverge in capacity and bandwidth. The RX 6400 has 4 GB of GDDR6 on a 64-bit bus, delivering 128.0 GB/s. The GTX 760M has 2 GB of GDDR5 on a 128-bit bus, delivering 64.13 GB/s. The RX 6400's narrower bus is compensated by its much faster memory type, resulting in exactly double the bandwidth. The RX 6400 also features 12 RT cores, which the GTX 760M completely lacks, and supports DirectX 12 Ultimate (12_2) versus the GTX 760M's DirectX 12 (11_0). Vulkan support also differs: the RX 6400 supports Vulkan 1.4, while the GTX 760M supports Vulkan 1.2.175.

Head-to-Head Benchmarks

The only two shared benchmark tests in the database are Geekbench OpenCL and Geekbench Vulkan, and the RX 6400 wins both by enormous margins.

In Geekbench OpenCL, the RX 6400 scores 32011 against the GTX 760M's 5604. This is a 471.2% delta, meaning the RX 6400 is nearly 5.7 times faster in this compute workload. The gap reflects not just the clock speed advantage but the architectural improvements in RDNA 2.0 over Kepler. OpenCL compute tasks such as physics simulation, image processing, and general-purpose GPU workloads will be dramatically faster on the RX 6400. The GTX 760M's score of 5604 is in the same range as its nearest rivals, the NVIDIA Quadro 4000M at 5211 and the AMD Radeon R7 M260X at 5161, confirming it is a low-end mobile part from its era.

In Geekbench Vulkan, the RX 6400 scores 16372 against the GTX 760M's 4868, a 236.3% delta. The RX 6400 is about 3.4 times faster in Vulkan. This is a smaller margin than OpenCL, but still a decisive victory. The RX 6400's Vulkan 1.4 support versus the GTX 760M's Vulkan 1.2.175 likely plays a role, as newer API versions enable better driver optimizations and feature utilization. The GTX 760M's Vulkan score of 4868 is consistent with its OpenCL result, showing a balanced but uniformly low level of performance.

The RX 6400 also has a wider benchmark footprint in the database, with additional results for 3DMark Steel Nomad DX12 (score 176), Passmark DirectX 10 (54), DirectX 11 (70), DirectX 12 (30), DirectX 9 (93), G2D (722), G3D (7673), and GPU Compute (2812). The GTX 760M has no recorded results in any of these tests, so direct comparisons are limited to the two Geekbench entries. However, the RX 6400's Passmark G3D score of 7673 and its 3DMark Steel Nomad result of 176 provide context for its overall capability: it is a low-end desktop card that can handle esports and older titles, but it is not built for high-end 3D workloads. The GTX 760M, based on its two recorded scores, would fall far below these figures if it had been tested in the same benchmarks.
