AMD Radeon R9 M265X vs NVIDIA Quadro M2000M Comparison

The NVIDIA Quadro M2000M and AMD Radeon R9 M265X are both end-of-life mobile graphics solutions, but the benchmark data reveals a clear performance hierarchy. The Quadro M2000M holds a decisive lead in the only shared test, the Geekbench OpenCL benchmark, scoring 10057 against the Radeon’s 8851. This represents a 13.6% advantage for the NVIDIA part. The data suggests that for users prioritizing raw compute performance in legacy mobile workstations, the Quadro M2000M is the superior choice. The Radeon R9 M265X, while an older design, still offers a functional level of performance, but it is outclassed by the newer NVIDIA architecture across the board.

The Verdict

Based strictly on the recorded measurements, the NVIDIA Quadro M2000M is the clear winner for users who need maximum compute throughput. Its Geekbench OpenCL score of 10057 places it in the 47th percentile of all GPUs, while the AMD Radeon R9 M265X sits in the 44th percentile with its score of 8851. The 13.6% delta in the head-to-head OpenCL test confirms that the Quadro is not just marginally faster, but significantly ahead in this workload. The Quadro also benefits from a higher average benchmark score of 9832 compared to the Radeon’s 8851, reinforcing its overall performance advantage.

The Radeon R9 M265X is the choice only if the specific system integration requires it, as it offers no performance benefit according to the data. Its nearest rival list includes the AMD Radeon Pro WX 5100 with an average score of 8863, a negligible 0.1% difference, and the AMD Radeon 550X with a score of 8918, which is 0.8% higher. This shows the R9 M265X is competitive with its immediate peers, but it cannot match the Quadro M2000M’s performance tier. The Quadro’s nearest rivals, such as the NVIDIA Quadro 6000 with a score of 9846 and the AMD FirePro W5000 with 9803, are all within a 0.5% margin, indicating that the Quadro M2000M performs at the top of its class.

Architecture Differences

The two GPUs are built on fundamentally different architectures. The NVIDIA Quadro M2000M uses the Maxwell architecture with the GM107 chip, while the AMD Radeon R9 M265X is based on the older GCN 1.0 architecture with the Venus chip. Both are manufactured on a 28 nm process at TSMC, but the transistor counts differ. The Quadro M2000M packs 1,870 million transistors on a 148 mm² die, resulting in a transistor density of 12.6M per mm². The Radeon R9 M265X has 1,500 million transistors on a smaller 123 mm² die, yielding a density of 12.2M per mm². This means the NVIDIA chip is both larger and denser, which contributes to its higher performance.

Both GPUs share the same core configuration in terms of shading units and texture mapping units, with 640 shading units and 40 TMUs each. They also both have 16 ROPs. However, the clock speeds are drastically different. The Quadro M2000M operates at a base clock of 1098 MHz with a boost clock of 1137 MHz, while the Radeon R9 M265X runs at a much lower base clock of 575 MHz and a boost of 625 MHz. This clock speed disparity is the primary driver of the performance gap. The memory clocks also differ, with the Quadro running at 1253 MHz (5 Gbps effective) and the Radeon at 1000 MHz (4 Gbps effective).

Head-to-Head Benchmarks

The only direct comparison available in the database is the Geekbench OpenCL test. In this benchmark, the NVIDIA Quadro M2000M scored 10057, while the AMD Radeon R9 M265X scored 8851. The Quadro won this test with a delta of 13.6%. This is a substantial margin that indicates a real-world performance difference in compute-heavy applications. The Quadro’s higher clock speeds and more efficient architecture allow it to pull ahead significantly.

The Quadro M2000M also has a higher average benchmark score of 9832, which is 11.1% higher than the Radeon’s 8851. This average score is a useful indicator of overall performance across multiple tests, and it reinforces the OpenCL result. While the Radeon R9 M265X has no other benchmark scores in the database, its single OpenCL score of 8851 is consistent with its 44th percentile ranking. The Quadro’s 47th percentile ranking, combined with its higher scores, shows that it is a more capable GPU for demanding tasks.

Specification Differences

The two GPUs differ in several key specification areas. The most obvious difference is memory capacity: the NVIDIA Quadro M2000M has 4 GB of GDDR5 memory, while the AMD Radeon R9 M265X has only 2 GB. Both use a 128-bit memory bus, but the Quadro’s higher memory clock of 1253 MHz gives it a bandwidth of 80.19 GB/s, compared to the Radeon’s 64.00 GB/s. This extra bandwidth is crucial for large datasets and high-resolution textures.

The compute capabilities also differ significantly. The Quadro M2000M has a pixel rate of 18.19 GPixel/s and a texture rate of 45.48 GTexel/s, while the Radeon R9 M265X has a pixel rate of 10.00 GPixel/s and a texture rate of 25.00 GTexel/s. The FP32 performance tells a similar story: the Quadro delivers 1,455.4 GFLOPS, while the Radeon delivers only 800.0 GFLOPS. The Quadro is nearly twice as fast in FP32 compute, which is a critical metric for scientific and professional workloads.

The TDP of the Quadro M2000M is listed as 55 W, while the Radeon R9 M265X has no TDP listed in the database. The Quadro is an MXM Module with a power connector requirement of "None" and uses an MXM-A (3.0) bus interface. The Radeon uses a PCIe 3.0 x16 interface. In terms of API support, the Quadro supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The Radeon supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The Quadro has a slightly newer Vulkan version, which may offer better compatibility with newer applications.

Where Each One Wins

The NVIDIA Quadro M2000M wins in every measurable performance category. Its higher clock speeds, larger memory capacity, and greater bandwidth make it the superior choice for compute-intensive tasks like rendering, scientific simulation, and professional content creation. The data shows it is 13.6% faster in the OpenCL benchmark, and its FP32 performance of 1,455.4 GFLOPS is nearly double the Radeon’s 800.0 GFLOPS. This makes the Quadro the obvious pick for users who need maximum performance from their mobile workstation.

The AMD Radeon R9 M265X, while slower, still holds a place for users who need a basic, functional GPU for less demanding tasks. Its 2 GB of memory and 64.00 GB/s bandwidth are sufficient for older games and standard 2D applications. The Radeon’s API support, including DirectX 12 (11_1), ensures compatibility with a wide range of software. However, the data does not show any scenario where the Radeon outperforms the Quadro. For users who already have a system with the R9 M265X, it can handle day-to-day workloads, but for those choosing between the two, the Quadro M2000M is the only logical choice based on benchmark results.
