AMD Radeon R5 M335 vs NVIDIA GeForce RTX 3080 12 GB Comparison

The data places the NVIDIA GeForce RTX 3080 12 GB and the AMD Radeon R5 M335 in the same performance percentile, but this is where the similarity ends. The RTX 3080 12 GB is a high-end desktop part from the GeForce 30-series, while the R5 M335 is an entry-level mobile chip from AMD’s older GCN 1.0 architecture. Their average benchmark scores sit within 0.8% of each other, yet they achieve that parity through wildly different means. This analysis breaks down what those scores actually mean, where each card wins, and who should choose which.

Head-to-Head Benchmarks

The benchmark results show a near-dead heat between these two GPUs, but the scores come from different test suites. The NVIDIA GeForce RTX 3080 12 GB was tested with the 3dmark_steel_nomad_dx12 workload, scoring 4791 points. The AMD Radeon R5 M335 was tested with two different benchmarks: geekbench_opencl scoring 4745 and geekbench_vulkan scoring 4758. Averaging those two results gives the R5 M335 a score of 4752. The delta between the two cards is a razor-thin 0.8%, with the RTX 3080 12 GB holding the edge.

Looking at the nearest rivals for each card puts this in perspective. The RTX 3080 12 GB’s closest competitor is the AMD Radeon R5 M255, which scores 4788 — just 0.1% behind. The R5 M335 is also in that same cluster, scoring 4752. The R5 M335’s own rival list shows the NVIDIA GeForce 940MX scoring 4844, which is 1.1% ahead of the RTX 3080 12 GB, and the NVIDIA GeForce GTX 560M at 4855, 1.3% ahead. For the R5 M335, the nearest rival is the AMD Radeon R8 M445DX at 4727 (0.5% behind), followed by the R5 M255 at 4788 (0.7% ahead) and the RTX 3080 12 GB at 4791 (0.8% ahead).

The key takeaway is that the RTX 3080 12 GB’s single 3DMark score of 4791 lands it in the 28th percentile of all GPUs. The R5 M335’s average of 4752 also places it in the 28th percentile. Both cards sit in the same percentile bracket, meaning they are statistically inseparable in this particular benchmark metric. However, the RTX 3080 12 GB was tested under a modern DirectX 12 Ultimate workload, whereas the R5 M335 was tested with OpenCL and Vulkan compute-style benchmarks. The data does not include head-to-head benchmark results, so no direct comparison under identical test conditions exists.

The Verdict

The data shows two GPUs that score nearly identically on paper, but the practical choice depends entirely on the use case. The NVIDIA GeForce RTX 3080 12 GB is a desktop card with 12 GB of GDDR6X memory, a 384-bit bus, and 912.4 GB/s of bandwidth. It is built on the Ampere architecture with 8960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6. It requires a 750 W power supply and uses a single 12-pin connector. It measures 285 mm in length and is dual-slot.

The AMD Radeon R5 M335 is a mobile chip with 2 GB of DDR3 memory on a 64-bit bus, providing 14.40 GB/s of bandwidth. It has 320 shading units, 20 TMUs, and 8 ROPs, with no RT or tensor cores. It supports DirectX 12 (11_1), Vulkan 1.2.170, and OpenGL 4.6. It consumes no external power connectors and is portable-device dependent for display outputs.

Who should pick which? If you need a desktop GPU for modern gaming with ray tracing and high-bandwidth memory, the RTX 3080 12 GB is the only option here. Its 70 RT cores and 280 tensor cores are features the R5 M335 simply does not have. If you need a low-power mobile chip for basic tasks in a laptop, the R5 M335 fits that role. However, the benchmark parity suggests that in pure compute terms, the R5 M335 is not significantly slower than the RTX 3080 12 GB in the specific tests run. That is a surprising result given the massive architectural gap, but the data is what it is. Neither card is a current product — both are marked end-of-life.

Architecture Differences

The architectural gap between these two GPUs is enormous. The NVIDIA GeForce RTX 3080 12 GB uses the GA102 chip, built on an 8 nm process at Samsung, with 28,300 million transistors on a 628 mm² die. The AMD Radeon R5 M335 uses the Exo chip on a 28 nm process at TSMC, with 690 million transistors on a 56 mm² die. That means the RTX 3080 12 GB has roughly 41 times more transistors and a die over 11 times larger.

The transistor densities tell the story of process maturity: the RTX 3080 12 GB packs 45.1 million transistors per mm², while the R5 M335 manages 12.3 million per mm². The RTX 3080 12 GB also runs on the Ampere architecture, while the R5 M335 is based on GCN 1.0. The R5 M335’s generation is labeled "Gem System (R5 M300)" and its predecessor is "Solar System," while the RTX 3080 12 GB’s predecessor is GeForce 20 and its successor is GeForce 40.

Feature-wise, the RTX 3080 12 GB includes dedicated RT cores (70) and tensor cores (280), which are absent from the R5 M335. The RTX 3080 12 GB supports PCIe 4.0 x16, while the R5 M335 uses PCIe 3.0 x8. The RTX 3080 12 GB outputs via 1x HDMI 2.1 and 3x DisplayPort 1.4a, whereas the R5 M335’s display outputs are portable-device dependent. The RTX 3080 12 GB has a base clock of 1260 MHz and a boost clock of 1710 MHz; the R5 M335 has no listed base or boost clocks. Memory clocks differ too: the RTX 3080 12 GB runs at 1188 MHz with 19 Gbps effective, while the R5 M335 runs at 900 MHz with 1800 Mbps effective.

The AMD Radeon R5 M335 wins in the categories that matter for mobile integration. It has no power connectors, meaning it draws power from the slot alone, while the RTX 3080 12 GB requires a 750 W PSU and a 12-pin connector. The R5 M335 has no listed TDP, slot width, or dimensions, which reflects its embedded mobile nature. It also supports Vulkan 1.2.170, which is older than the RTX 3080 12 GB’s Vulkan 1.4, but it does support OpenGL 4.6 just like the RTX 3080 12 GB. In benchmark terms, the R5 M335’s geekbench_vulkan score of 4758 is close to its opencl score of 4745, showing consistency across different APIs.

For use cases, the RTX 3080 12 GB is suited for desktop gaming, content creation, and any workload that benefits from ray tracing, tensor cores, or high-bandwidth memory. The R5 M335 is suited for basic laptop graphics, video playback, and light 2D workloads where low power draw and no external power requirement are advantages. The data does not show the R5 M335 winning any benchmark head-to-head against the RTX 3080 12 GB, but its existence in the same percentile bracket suggests that for the specific tests used, the performance gap is negligible.
