AMD Radeon 540 vs AMD Radeon R9 M360 Comparison

The AMD Radeon R9 M360 and AMD Radeon 540 are two end-of-life mobile graphics solutions from different generations, and the benchmark data reveals a split decision. The R9 M360 is a GCN 1.0 part from the R9 M300 series, while the Radeon 540 is a GCN 4.0 Polaris part. In the two head-to-head tests, each card claims one victory, but the magnitude of those wins and the underlying specifications tell a clear story about their respective strengths. The data shows that the older R9 M360 dominates in OpenCL compute workloads, while the newer Radeon 540 pulls ahead in Vulkan graphics performance, making the choice between them dependent on the specific application.

Head-to-Head Benchmarks

The most striking result in the head-to-head comparison is the Geekbench OpenCL test, where the AMD Radeon R9 M360 scores 8211 against the Radeon 540's 6184. This is a decisive 32.8% advantage for the older card. The R9 M360's margin is substantial, placing it nearly on par with the NVIDIA GeForce GTX 950M, which has an average score of 8135 and a delta of -0.1% relative to the R9 M360. This suggests that for compute-heavy tasks that leverage OpenCL, the R9 M360 is the more capable piece of hardware, despite its age.

The tables turn completely in the Geekbench Vulkan test. Here, the AMD Radeon 540 scores 9162, while the R9 M360 manages only 8047. This represents a 12.2% lead for the Radeon 540. This is a significant swing in performance. The Radeon 540's Vulkan score is not only higher than its own OpenCL score, but it also positions it competitively against its nearest rivals. Its average benchmark score of 7673 is only 0.6% behind the NVIDIA GeForce GTX 1660 Ti, which averages 7723, and it sits 1.2% ahead of the AMD Radeon Pro WX 3100 (7580). The R9 M360, in contrast, sees a slight drop from its OpenCL score to its Vulkan score, indicating that its architecture handles the older API more efficiently.

Looking at the average benchmark scores, the R9 M360 holds a narrow edge overall. It averages 8129 across its two tests, while the Radeon 540 averages 7673. That is a difference of roughly 5.6% in favor of the R9 M360. However, this aggregate number masks the divergent performance profiles. The R9 M360's average is propped up by its massive OpenCL win, while the Radeon 540's average is dragged down by its weaker OpenCL showing. The percentile rankings are close, with the R9 M360 at the 42nd percentile and the Radeon 540 at the 41st percentile, confirming that both are mid-to-low-tier performers in the overall GPU landscape. For a builder, this means the R9 M360 is the safer bet for general-purpose compute, but the Radeon 540 is the one to pick for modern graphics APIs.

Architecture Differences

The two cards are built on fundamentally different architectures and manufacturing processes. The AMD Radeon R9 M360 uses the Tropo chip, which is based on the GCN 1.0 architecture, and is manufactured on a 28 nm process at TSMC. In contrast, the AMD Radeon 540 uses the Lexa chip, based on the newer GCN 4.0 architecture, and is built on a 14 nm process at GlobalFoundries. This generational leap is significant. The Radeon 540's 14 nm node allows for a smaller die size of 103 mm², compared to the R9 M360's 123 mm², even though the Radeon 540 packs more transistors. Specifically, the Radeon 540 has 2,200 million transistors versus 1,500 million on the R9 M360. This results in a much higher transistor density for the newer card: 21.4M / mm² versus 12.2M / mm².

The compute units also differ. The R9 M360 has 512 shading units, 32 texture mapping units (TMUs), and 16 ROPs. The Radeon 540 has fewer shading units at 384, and fewer TMUs at 24, but it also has 16 ROPs. This means the R9 M360 has a theoretical texture fillrate of 29.60 GTexel/s, which is slightly higher than the Radeon 540's 28.39 GTexel/s. However, the Radeon 540 has a higher pixel rate at 18.93 GPixel/s versus the R9 M360's 14.80 GPixel/s. In terms of raw FP32 compute, the R9 M360 is marginally ahead with 947.2 GFLOPS compared to the Radeon 540's 908.5 GFLOPS. Notably, the Radeon 540 also supports FP16 at a 1:1 ratio (908.5 GFLOPS), while the R9 M360 has no FP16 data listed.

The memory subsystems are starkly different. The R9 M360 features 4 GB of GDDR5 on a 128-bit bus, delivering 72.00 GB/s of bandwidth. The Radeon 540, on the other hand, has only 1024 MB (1 GB) of GDDR5 on a very narrow 32-bit bus, resulting in just 24.00 GB/s of bandwidth. This is a massive difference—the R9 M360 has three times the memory bandwidth. The Radeon 540 also has a higher effective memory clock of 6 Gbps versus 4.5 Gbps on the R9 M360, but the narrow bus width cripples its overall throughput. The Radeon 540's PCIe interface is also narrower at PCIe 3.0 x8, compared to the R9 M360's PCIe 3.0 x16.

Where Each One Wins

The benchmark data points to a clear use-case split. The AMD Radeon R9 M360 is the winner for compute-oriented tasks. Its 32.8% lead in OpenCL performance makes it the obvious choice for applications that rely heavily on this API, such as certain rendering, simulation, or data-processing workloads. The larger 4 GB frame buffer and the 128-bit memory bus also give it a significant edge in scenarios where large datasets need to be held in VRAM, even if the raw compute is only slightly higher. The R9 M360's higher FP32 throughput (947.2 GFLOPS) supports this, as does its higher texture rate.

Conversely, the AMD Radeon 540 is the winner for modern graphics APIs. Its 12.2% advantage in the Vulkan benchmark is a strong indicator that it is better suited for newer games and applications that use Vulkan. The architecture's support for DirectX 12 (12_0) and Vulkan 1.3—versus DirectX 12 (11_1) and Vulkan 1.2.170 on the R9 M360—ensures better compatibility and performance in current software. The Radeon 540's higher pixel rate (18.93 GPixel/s) also suggests it can handle fill-rate-limited scenarios more effectively. However, the 1 GB memory capacity is a severe limitation for modern games, which often require more VRAM at higher resolutions and detail settings. The Radeon 540's lack of a base or boost clock listing in the data is notable, but its performance in Vulkan speaks for itself.

The Verdict

Based strictly on the data, the choice hinges on the workload. For users who prioritize compute performance in OpenCL environments, the AMD Radeon R9 M360 is the clear winner. Its 32.8% benchmark advantage, larger 4 GB frame buffer, and higher memory bandwidth make it the more capable card for tasks that are not dependent on the latest graphics APIs. The R9 M360's average score of 8129 is also higher, and it sits at the 42nd percentile, just above the Radeon 540's 41st percentile.

However, for gaming or any application that leverages Vulkan, the AMD Radeon 540 is the better option. Its 12.2% lead in the Vulkan benchmark, combined with modern API support (DirectX 12_0, Vulkan 1.3), makes it more future-proof for software that uses these newer interfaces. The Radeon 540's lower power draw (50 W TDP) and lack of power connectors also make it a simpler drop-in solution for systems with limited power delivery. Its main drawback is the paltry 1 GB VRAM, which will be a bottleneck in memory-intensive scenarios. The verdict is straightforward: pick the R9 M360 for raw compute and memory capacity, or pick the Radeon 540 for modern API compatibility and efficiency.
