AMD Radeon R7 M465 vs NVIDIA GeForce GTX 980M Comparison

Head-to-Head Benchmarks

The only direct head-to-head benchmark recorded in the database is Geekbench OpenCL, and the result is decisive. The NVIDIA GeForce GTX 980M scores 23,832, while the AMD Radeon R7 M465 scores 5,841. That puts the GTX 980M 75.5% ahead, a margin so large that it defines the entire comparison.

To put the R7 M465's score in context, it sits at the 33rd percentile among all GPUs in the database. Its nearest rivals are all within a narrow band: the AMD Radeon R5 M435 scores 5,859 (0.3% higher), the Intel UHD Graphics 730 scores 5,929 (1.5% higher), the NVIDIA GeForce GTX 550 Ti scores 5,731 (1.9% lower), and the AMD Radeon HD 8730M scores 5,955 (1.9% higher). The M465 is essentially in a dead heat with those parts, which means its OpenCL result is firmly entry-level territory. It is neither a standout nor a laggard within its immediate peer group; it simply occupies a crowded middle of low-end mobile graphics.

The GTX 980M, by contrast, has an average benchmark score of 5,308 across all recorded tests, but that average is dragged down by several older DirectX tests. Its nearest rivals by average score are the NVIDIA GeForce 930A (5,317, 0.2% higher), the NVIDIA GeForce 840M (5,322, 0.3% higher), the NVIDIA GeForce 940M (5,284, 0.5% lower), and the AMD Radeon R7 M445 (5,358, 0.9% higher). That average is misleading for the 980M because its individual results vary wildly by API generation. In Passmark DirectX 9 it scores 125, in DirectX 10 it drops to 35, in DirectX 11 it climbs to 57, and in DirectX 12 it falls to 31. Its Passmark G3D score is 7,338, and its Passmark GPU compute score is 2,816. The 980M also records a Geekbench Vulkan score of 17,703 and a 3DMark Steel Nomad DX12 score of 649.

The pattern is clear: the GTX 980M is a high-end part that excels in modern compute and graphics workloads, while the R7 M465 is a low-end part that barely moves the needle. The 75.5% OpenCL deficit for the M465 is not a marginal gap; it is a generational and tier-level chasm. There are no other head-to-head tests recorded, so the database offers a single, unambiguous data point, but that one point tells the story.

The Verdict

The data leaves little room for debate. The NVIDIA GeForce GTX 980M wins the only recorded head-to-head benchmark by 75.5%, and it does so with hardware that is in a completely different performance class. Anyone choosing between these two for gaming, 3D rendering, or GPU compute should take the 980M without hesitation, provided the system can physically accommodate an MXM module and its power requirements.

The AMD Radeon R7 M465 is not without merit, but its merit lies in being a low-power, low-cost mobile solution for basic tasks. Its OpenCL score of 5,841 places it alongside the R5 M435 and HD 8730M, which are all entry-level parts. The M465 has no recorded wins in the head-to-head comparison, and its 33rd percentile ranking among all GPUs confirms it is near the bottom of the performance distribution.

The GTX 980M's percentile ranking of 31 appears lower than the M465's 33, but that is an artifact of the broader test suite. The 980M was tested across many more workloads, including older DirectX versions where it scores poorly (35 in DX10, 31 in DX12 Passmark), which pulls its percentile down. In the tests that matter for modern use, namely Geekbench OpenCL, Geekbench Vulkan, and Passmark G3D, the 980M is overwhelmingly faster. The M465 has only one recorded benchmark, so its percentile is based on a single score.

For a buyer today, the choice depends on what the machine will do. If the task is modern gaming or compute, the GTX 980M is the only rational pick. If the task is basic office work, video playback, or light 2D acceleration, the M465 can suffice, but the database shows no scenario where it outperforms the 980M. The verdict is straightforward: the GTX 980M is the superior GPU by every recorded metric.

Architecture Differences

The two GPUs come from different architectural generations and different design philosophies. The AMD Radeon R7 M465 uses the Topaz chip built on GCN 3.0 architecture, manufactured on a 28 nm process at TSMC. The NVIDIA GeForce GTX 980M uses the GM204 chip built on Maxwell 2.0 architecture, also manufactured on a 28 nm process at TSMC. Both share the same process node and foundry, but the silicon designs diverge sharply.

The transistor counts tell the story. The M465 packs 1,550 million transistors on a 125 mm² die, yielding a transistor density of 12.4M per mm². The GTX 980M packs 5,200 million transistors on a 398 mm² die, yielding a density of 13.1M per mm². The 980M has more than three times the transistor budget and more than three times the die area. That extra silicon is put to work across every major compute unit.

The M465 has 384 shading units, 24 texture mapping units, and 8 render output units. The GTX 980M has 1,536 shading units, 96 TMUs, and 64 ROPs. Those are exactly four times the counts of the M465 in each category, which explains why the 980M's pixel rate is 72.13 GPixel/s versus 8.192 GPixel/s for the M465, and why its texture rate is 108.2 GTexel/s versus 24.58 GTexel/s. The 980M also delivers 3.462 TFLOPS of FP32 compute, while the M465 delivers 786.4 GFLOPS. The M465 supports FP16 at a 1:1 ratio with FP32, while the 980M has no recorded FP16 capability.

Architecturally, GCN 3.0 and Maxwell 2.0 differ in how they schedule work, handle geometry, and manage power. Maxwell 2.0 introduced improved color compression and a more efficient scheduler, which helps explain the 980M's strong performance per clock. GCN 3.0 is a compute-oriented design that scales well with raw throughput but does not match Maxwell's efficiency in gaming workloads. The API support also differs: the M465 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, while the 980M supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The 980M's higher DirectX feature level and newer Vulkan version give it an edge in modern titles that use those APIs.

Specification Differences

The two GPUs differ in nearly every specification that affects performance. The M465 has 2 GB of GDDR5 memory on a 64-bit bus, delivering 36.00 GB/s of bandwidth. The GTX 980M has 8 GB of GDDR5 memory on a 256-bit bus, delivering 160.4 GB/s of bandwidth. That is more than four times the memory capacity and more than four times the bandwidth, a critical difference for high-resolution textures and large compute workloads.

Clock speeds favor the 980M as well. The M465 runs at a base clock of 730 MHz with a boost of 1024 MHz and memory at 1125 MHz (4.5 Gbps effective). The 980M runs at a base clock of 1038 MHz with a boost of 1127 MHz and memory at 1253 MHz (5 Gbps effective). The 980M's higher clocks compound its massive compute unit advantage.

The bus interface differs completely. The M465 uses PCIe 3.0 x8, which is typical for a low-end mobile chip. The GTX 980M uses an MXM-B (3.0) interface, meaning it is a modular graphics card designed for laptops with MXM slots. The 980M is listed as an MXM Module with no power connectors, and its display outputs are portable device dependent. The M465 has no recorded slot width, power connector, or display output data.

Process node and foundry are identical: both are 28 nm TSMC parts. Transistor density is similar, with the 980M at 13.1M per mm² versus 12.4M per mm² for the M465. The production status for both is end-of-life. The M465 launched on 2016-05-14, while the 980M launched earlier on 2014-10-06. The M465's predecessor is Solar System and its successor is Polaris Mobile. The 980M's predecessor is GeForce 800M and its successor is GeForce 10 Mobile.

Where Each One Wins

The GTX 980M wins every recorded head-to-head comparison, and its advantage extends across multiple test categories. In Geekbench OpenCL, it is 75.5% ahead. In Geekbench Vulkan, it scores 17,703, a result the M465 cannot match since it has no recorded Vulkan score. In Passmark G3D, the 980M scores 7,338, and in Passmark GPU compute it scores 2,816. The 980M also holds a 3DMark Steel Nomad DX12 score of 649, a modern workload test. For gaming, 3D rendering, video encoding, or any GPU-accelerated compute task, the 980M is the clear winner.

The M465 does not win any recorded benchmark against the 980M. Its only recorded score is Geekbench OpenCL at 5,841, which places it in the 33rd percentile among all GPUs. Its nearest rivals are all within 2%, which means it performs at the level of an entry-level mobile GPU. The M465 could be a reasonable choice for a lightweight laptop where power draw and heat are primary concerns, but the database does not record any performance scenario where it beats the 980M.

The use-case split is therefore simple. The GTX 980M is for anyone who needs real graphics performance in a laptop: gamers, 3D artists, video editors, or users running CUDA or OpenCL workloads. The M465 is for basic desktop and office tasks, media playback, and legacy applications where the GPU is not a bottleneck. The 980M's 8 GB of VRAM and 160.4 GB/s bandwidth make it suitable for high-resolution textures and large datasets, while the M465's 2 GB and 36.00 GB/s are enough only for light workloads. There is no recorded scenario where the M465 wins, so the recommendation is unambiguous.
