AMD Radeon Vega 10 Mobile vs NVIDIA GeForce GTX 765M Comparison

The Verdict

The recorded data presents a clear, though narrow, outcome in the single shared benchmark. In the Geekbench OpenCL test, the NVIDIA GeForce GTX 765M scores 7176, while the AMD Radeon Vega 10 Mobile scores 6476. This gives the GTX 765M a 9.8% advantage in this specific workload. The AMD part is not without merit, however, as its raw compute metrics and modern feature set make it a more compelling choice for specific tasks.

For general-purpose compute tasks, the NVIDIA GeForce GTX 765M is the stronger performer. Its 10% lead in the OpenCL benchmark is a significant margin, placing it comfortably ahead of the AMD IGP in raw throughput. However, the GTX 765M is a 75 W MXM module from 2013, which is a heavy power draw for a notebook. The AMD Radeon Vega 10 Mobile, being an IGP, is fundamentally a different class of component, requiring 10 W.

For users prioritizing maximum power efficiency and a modern feature set, the AMD is the better pick. The data shows the Radeon consumes 65 W less power while offering DirectX 12 (12_1) support and Vulkan 1.3, compared to the GTX 765M's DirectX 12 (11_0) and Vulkan 1.2.175. The GTX 765M is an end-of-life product from an older generation, and its higher performance comes with the cost of being a larger, more power-hungry module. The choice hinges on whether you value the performance edge or the efficiency and architectural longevity.

Architecture Differences

The two GPUs represent divergent design philosophies and eras. The AMD Radeon Vega 10 Mobile is built on the GCN 5.0 architecture using a 14 nm process from GlobalFoundries. It is an IGP, meaning it is integrated into a processor package (Raven-M). The NVIDIA GeForce GTX 765M is based on the older Kepler architecture, manufactured on TSMC's 28 nm process. It is a discrete MXM module.

The die sizes are similar: the AMD chip is 210 mm² with 4,940 million transistors, while the NVIDIA chip is 221 mm² with 2,540 million transistors. This results in a stark difference in transistor density: 23.5M / mm² for AMD versus 11.5M / mm² for NVIDIA. The AMD uses a "System Shared" memory model, pulling from the host's memory, which makes the bandwidth "System Dependent". The NVIDIA, in contrast, has dedicated memory with a fixed bandwidth.

The feature sets also differ. The AMD Radeon Vega 10 Mobile supports DirectX 12 (12_1) and Vulkan 1.3, which are more modern API versions. The GTX 765M's maximum DirectX support is 12 (11_0), and it has Vulkan 1.2.175. The AMD does not have a dedicated FP16 score, but its FP32 output is 1.665 TFLOPS, while the NVIDIA's FP32 is 1,325.6 GFLOPS. The AMD is a 10 W part, while the NVIDIA is a 75 W part, reflecting a trade-off between performance and power consumption.

Head-to-Head Benchmarks

The database records a single shared benchmark: Geekbench OpenCL. In this test, the NVIDIA GeForce GTX 765M is the winner. It scores 7176 points, while the AMD Radeon Vega 10 Mobile scores 6476 points. The delta percentage is -9.8% from the perspective of the AMD, meaning the AMD is 9.8% slower than the GTX 765M in this workload.

This result is notable because it puts the GTX 765M in a higher performance class. The AMD's nearest rivals in the database include the NVIDIA Quadro M5000M (6481 score, -0.1% delta) and the NVIDIA GeForce GT 555M (6493 score, -0.3% delta), which are extremely close to its score of 6476. The GTX 765M sits in a different bracket, with its nearest rivals being the NVIDIA GeForce MX130 (5508 score, -0.1% delta) and the AMD Radeon R7 M440 (5483 score, +0.3% delta). However, the GTX 765M's average benchmark score is 5501, which is lower than its single OpenCL score.

The data shows the GTX 765M has a higher pixel rate (13.81 GPixel/s vs 10.41 GPixel/s), a higher texture rate (55.23 GTexel/s vs 52.04 GTexel/s), and a higher FP32 performance (1,325.6 GFLOPS vs 1.665 TFLOPS). Despite these advantages, the AMD's newer architecture demonstrates higher FP16 performance (3.331 TFLOPS vs null for the GTX 765M), which could be relevant for specific compute workloads.

Where Each One Wins

The AMD Radeon Vega 10 Mobile wins on efficiency and modern platform integration. Its 10 W TDP is a fraction of the GTX 765M's 75 W TDP, making it the only choice for a thin-and-light laptop where battery life and thermals are paramount. The AMD also wins on API support, with DirectX 12_1 and Vulkan 1.3, ensuring broader compatibility with newer software titles that leverage these modern standards. It also offers higher FP16 compute (3.331 TFLOPS) and a higher transistor density (23.5M / mm²), which indicates a more advanced manufacturing process. Its release in 2019 also makes it a much newer part.

The NVIDIA GeForce GTX 765M wins on raw performance and memory bandwidth. The benchmark data shows it is 9.8% faster than the AMD in the only recorded test. It has a dedicated 2 GB GDDR5 memory with a 64.13 GB/s bandwidth, which is a significant advantage over the AMD's system-dependent memory. The GTX 765M also has more shading units (768 vs 640), more ROPs (16 vs 8), and a higher pixel rate (13.81 GPixel/s vs 10.41 GPixel/s). This makes it the more capable option for a gaming laptop, even if it is an older, more power-hungry design. This is the GPU for the user who prioritizes frame rates and compute performance over power draw.
