AMD Radeon RX 6500M vs NVIDIA GeForce GTX 465 Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark between these two GPUs is the Geekbench OpenCL test, and the result is decisively lopsided. The AMD Radeon RX 6500M scores 38,586 points, while the NVIDIA GeForce GTX 465 manages just 9,294 points. That is a 315.2% advantage for the AMD part, a margin that dwarfs anything seen in typical generational improvements.

To put that gap in context, the RX 6500M's average benchmark score across all recorded tests sits at 10,362. The GTX 465's average is 9,294. The RX 6500M lands at the 48th percentile of all GPUs in the database, while the GTX 465 sits at the 46th percentile. Despite the massive OpenCL delta, both cards occupy similar overall standing because the GTX 465's single recorded benchmark is its only data point, while the RX 6500M has nine separate test results pulling its average in different directions.

The RX 6500M also holds a clear edge in raw compute metrics. Its FP32 throughput is listed at 4.915 TFLOPS, compared to 855.4 GFLOPS for the GTX 465. That is roughly 5.7 times the floating-point output, which aligns with the 315.2% OpenCL win. The texture rate tells a similar story: 153.6 GTexel/s versus 26.75 GTexel/s. Pixel rate is less extreme but still favors AMD, at 76.80 GPixel/s versus 13.38 GPixel/s.

The GTX 465 does not win a single head-to-head benchmark in this comparison. The database records zero wins for the NVIDIA card. Its only consolation is that it remains within striking distance of the RX 6500M in overall percentile ranking, but that is a function of limited testing rather than competitive performance.

The Verdict

The data is unambiguous. The AMD Radeon RX 6500M outperforms the NVIDIA GeForce GTX 465 by a 315.2% margin in the sole shared benchmark. Any user choosing between these two based on measured performance should select the RX 6500M without hesitation.

However, the GTX 465 does have one attribute the RX 6500M lacks: a recorded launch MSRP of 279 USD. That figure appears once in the database and reflects a 2010-era product. The RX 6500M has no launch MSRP listed, so no direct price comparison is possible from the recorded data.

For users running legacy software with DirectX 9 or DirectX 10 workloads, the GTX 465's architecture may still function, but the benchmark evidence suggests it will do so at a fraction of the speed. The RX 6500M's PassMark DirectX 9 score of 92 and DirectX 10 score of 52 are not directly comparable to the GTX 465 because that card only has an OpenCL result recorded. Still, the overall compute advantage for AMD is overwhelming.

Pick the RX 6500M for any modern workload. Pick the GTX 465 only if you specifically need a dual-slot card with 2x 6-pin power connectors, a 550 W suggested PSU, and a 241 mm (9.5 inches) length, and you are willing to accept dramatically lower performance.

Architecture Differences

The AMD Radeon RX 6500M uses the Navi 24 chip built on RDNA 2.0 architecture, manufactured on a 6 nm process at TSMC. It packs 5,400 million transistors into a 107 mm² die, yielding a transistor density of 50.5 million per square millimeter. The GTX 465 uses the GF100 chip based on Fermi architecture, also built at TSMC but on a much older 40 nm node. It contains 3,100 million transistors spread across a 529 mm² die, resulting in just 5.9 million transistors per square millimeter.

The memory subsystems could hardly be more different. The RX 6500M has 4 GB of GDDR6 memory on a 64-bit bus, delivering 144.0 GB/s of bandwidth. The GTX 465 has 1024 MB of GDDR5 memory on a 256-bit bus, providing 102.7 GB/s. AMD achieves higher bandwidth with a quarter of the bus width, thanks to faster memory clocks: 18 Gbps effective versus 3.2 Gbps effective.

Compute resources favor AMD heavily. The RX 6500M has 1,024 shading units, 64 texture mapping units, 32 ROPs, and 16 ray tracing cores. The GTX 465 has 352 shading units, 44 TMUs, and 32 ROPs, with no ray tracing support. The RX 6500M also supports FP16 at 9.830 TFLOPS (2:1 ratio), while the GTX 465 has no recorded FP16 capability.

Power and physical characteristics diverge significantly. The RX 6500M is rated at 50 W TDP and is an IGP (integrated graphics processor) with no power connectors and no dedicated slot width. The GTX 465 draws 200 W, requires a dual-slot cooler, two 6-pin power connectors, and a 550 W suggested PSU. The RX 6500M connects via PCIe 4.0 x4, while the GTX 465 uses PCIe 2.0 x16.

API support shows the generational leap. The RX 6500M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GTX 465 supports DirectX 12 (11_0) and OpenGL 4.6, but has no recorded Vulkan support. Display outputs on the RX 6500M are listed as portable device dependent, while the GTX 465 offers 2x DVI and 1x mini-HDMI 1.3a.

Where Each One Wins

The AMD Radeon RX 6500M wins in every measurable performance category. It dominates OpenCL compute with a 315.2% lead. It has higher FP32 throughput (4.915 TFLOPS versus 855.4 GFLOPS), higher texture rate (153.6 GTexel/s versus 26.75 GTexel/s), and higher pixel rate (76.80 GPixel/s versus 13.38 GPixel/s). It also wins on efficiency, drawing 50 W compared to 200 W, and on modern features like ray tracing, Vulkan 1.4, and DirectX 12 Ultimate support. For any workload involving current APIs, high-resolution textures, or compute acceleration, the RX 6500M is the clear choice.

The NVIDIA GeForce GTX 465 wins only in niche hardware-specific scenarios. It has a wider 256-bit memory bus, which can be advantageous in certain legacy bandwidth-sensitive workloads, but that advantage is negated by its lower effective memory speed (3.2 Gbps versus 18 Gbps). It also offers a dual-slot form factor with 2x DVI and mini-HDMI outputs, which may be preferable for users with older displays that lack modern connectors. The GTX 465's 241 mm (9.5 inches) length and 550 W suggested PSU requirement make it a poor fit for compact or power-constrained systems.

In terms of overall benchmark standing, the RX 6500M's 48th percentile versus the GTX 465's 46th percentile is close, but that masks the reality: the RX 6500M has nine recorded benchmark results, while the GTX 465 has only one. The single data point for NVIDIA is its OpenCL score, which is the very test where AMD leads by 315.2%. The GTX 465's nearest rivals include the GeForce GTX 850M (0.1% slower), Radeon R7 M380 (0.2% slower), GTX 960 (0.2% faster), and Radeon Vega 8 (0.8% faster). These rivals are all modern or near-modern parts, indicating the GTX 465 sits at the bottom of its performance class. For any user with a choice, the data points squarely to the RX 6500M.
