The AMD Radeon HD 8730M scores 5,955, 1.9% higher. Only the NVIDIA GeForce GTX 550 Ti, at 5,731, sits below it, and that gap is 1.9%. These are all small deltas, indicating that the R7 M465 is firmly in the low-end mobile performance tier.

Architecture Differences

The two GPUs come from different architectural generations and are built on different process nodes. The AMD Radeon Pro WX 4100 uses the Baffin chip based on GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It packs 3,000 million transistors into a 123 mm² die, yielding a transistor density of 24.4 million per square millimeter. The R7 M465 uses the Topaz chip based on GCN 3.0 architecture, built on a 28 nm process at TSMC. It contains 1,550 million transistors on a 125 mm² die, giving a transistor density of just 12.4 million per square millimeter. Despite similar die sizes, the Pro WX 4100 fits nearly twice the transistor count into the same area.

The compute resources differ substantially. The Pro WX 4100 has 1,024 shading units, 64 texture mapping units, and 16 raster operation pipelines. The R7 M465 has 384 shading units, 24 TMUs, and 8 ROPs. That is roughly 2.7 times the shading units and TMUs in the Pro WX 4100, and double the ROP count. These structural differences translate directly into throughput figures: the Pro WX 4100 reaches 2.460 TFLOPS of FP32 and FP16 compute, while the R7 M465 reaches 786.4 GFLOPS in both. Pixel rate is 19.22 GPixel/s versus 8.192 GPixel/s, and texture rate is 76.86 GTexel/s versus 24.58 GTexel/s.

Clock speeds also favor the Pro WX 4100. Its base clock is 1,125 MHz with a boost of 1,201 MHz. The R7 M465 runs at a base of 730 MHz and boosts to 1,024 MHz. Even the boost clock on the R7 M465 falls short of the Pro WX 4100's base clock. Memory configurations reinforce the gap: the Pro WX 4100 has 4 GB of GDDR5 on a 128-bit bus with 96.00 GB/s of bandwidth and a 6 Gbps effective memory speed. The R7 M465 has 2 GB of GDDR5 on a 64-bit bus with 36.00 GB/s of bandwidth and a 4.5 Gbps effective speed. The Pro WX 4100 offers triple the memory bandwidth.

Feature support is similar in some respects. Both support DirectX 12 (12_0), OpenGL 4.6, and Vulkan (1.3 on the Pro WX 4100, 1.2.170 on the R7 M465). Both use a PCIe 3.0 x8 bus interface. Neither has dedicated ray tracing or tensor cores. The Pro WX 4100 is a single-slot card with four mini-DisplayPort 1.4a outputs and no power connectors, while the R7 M465 has no recorded display outputs, slot width, or power connector details, consistent with a mobile part.

The process node advantage is worth emphasizing. The 14 nm GlobalFoundries process versus the 28 nm TSMC process explains much of the efficiency and density difference. The Pro WX 4100 is rated at 50 W TDP with a suggested power supply of 250 W. The R7 M465 has no recorded TDP or power supply requirement in the database, but its older, larger process node and lower transistor count point to a less efficient design. The R7 M465 also uses the older GCN 3.0 architecture, while the Pro WX 4100 benefits from GCN 4.0 improvements.

Where Each One Wins

The AMD Radeon Pro WX 4100 wins in every measurable category in the database. It is faster in Geekbench OpenCL by 202%, and it has scores in nine additional benchmark tests that the R7 M465 simply does not have recorded. Its Passmark scores include 56 in DirectX 9, 24 in DirectX 11, 22 in DirectX 12, 16 in DirectX 10, 646 in G2D, 3,699 in G3D, and 1,475 in GPU compute. Geekbench Metal and Vulkan scores are 21,018 and 18,703 respectively. For workloads that rely on compute throughput, memory bandwidth, or pixel and texture rates, the Pro WX 4100 is decisively ahead.

The R7 M465 has no recorded wins in any benchmark. Its sole score of 5,841 in Geekbench OpenCL is less than one-third of the Pro WX 4100's result. However, the R7 M465 is not without a rationale for existence. Its 33rd percentile ranking, while lower than the Pro WX 4100's 37th, is not drastically different. The R7 M465's nearest rivals include integrated graphics like the Intel UHD Graphics 730 and low-end discrete parts like the Radeon R5 M435, which suggests it is positioned for basic display output and light GPU tasks rather than heavy compute.

Use-case separation comes down to the fundamental design intent. The Pro WX 4100 is a professional workstation card, evidenced by its Radeon Pro branding, four display outputs, and single-slot form factor. It is designed for multi-monitor professional environments, compute acceleration, and sustained workloads. The R7 M465 is a mobile discrete GPU from the R7 M400 generation, aimed at mainstream laptops for everyday graphics, video playback, and light gaming. The absence of recorded display outputs and power connector details for the R7 M465 reinforces its mobile, integrated-laptop nature.

Memory capacity also differentiates use cases. The Pro WX 4100's 4 GB frame buffer with 96.00 GB/s bandwidth is suitable for larger textures and compute workloads. The R7 M465's 2 GB buffer with 36.00 GB/s bandwidth will hit capacity and bandwidth limits much sooner. For users working with large datasets, multiple monitors, or GPU-accelerated applications, the Pro WX 4100 has a clear edge. For basic laptop use where power draw and physical space matter more than raw throughput, the R7 M465 fits a different niche.

The Verdict

The data is unambiguous: the AMD Radeon Pro WX 4100 is the superior GPU by a wide margin. Its 202% lead in Geekbench OpenCL, combined with its higher shading unit count, faster clocks, larger memory bus, and triple the memory bandwidth, makes it the only rational choice for any compute-oriented workload. The Pro WX 4100 also benefits from a newer architecture (GCN 4.0 versus GCN 3.0), a more advanced 14 nm process, and a transistor density nearly double that of the R7 M465. Its percentile ranking of 37 places it above the R7 M465's 33, and its average benchmark score of 6,330 versus 5,841 reflects a consistent performance advantage.

Who should pick the Pro WX 4100? Anyone running GPU-accelerated professional applications, managing multiple 4K displays via the four mini-DisplayPort 1.4a outputs, or needing reliable compute performance in a single-slot, 50 W package. Its launch MSRP was 399 USD, and it offers workstation-grade features like 4 GB of VRAM and support for modern APIs including Vulkan 1.3 and DirectX 12 (12_0). The suggested 250 W power supply is modest, and the card requires no external power connectors, making it easy to integrate into a workstation build.

Who should pick the R7 M465? Strictly from the data, it is hard to recommend it over the Pro WX 4100 for any performance-sensitive task. Its only recorded benchmark shows it at 5,841 in Geekbench OpenCL, and its nearest rivals are all within roughly 2% of its score, indicating a low-performance ceiling. It is an end-of-life mobile GPU from 2016, with no recorded TDP, dimensions, or display outputs. For a laptop where the GPU is fixed at purchase time, the R7 M465 is what it is: a basic discrete part for everyday use. But given a choice between these two, the Pro WX 4100 wins every benchmark contest in the database.

The verdict is simple. The Pro WX 4100 is in a different performance class, and the recorded data supports no other conclusion.
