AMD FirePro W5000 vs AMD Radeon R9 M265X Comparison

Head-to-Head Benchmarks

The recorded database contains a single head-to-head benchmark between these two AMD GPUs: Geekbench OpenCL. In that test, the AMD FirePro W5000 scores 9803, while the AMD Radeon R9 M265X scores 8851. The FirePro W5000 wins by a margin of 10.8%. This is a decisive gap, placing the two cards in different performance tiers despite sharing the same GCN 1.0 architecture generation.

Looking at the broader database context, the FirePro W5000 sits at the 47th percentile of all GPUs, while the Radeon R9 M265X sits at the 44th percentile. That three-percentile difference reflects the measured 10.8% gap in raw OpenCL compute performance. The FirePro's nearest rivals include the NVIDIA GeForce GTX 1070 (9780, a 0.2% deficit), the NVIDIA Quadro M2000M (9832, a 0.3% advantage), and the NVIDIA Quadro 6000 (9846, a 0.4% advantage). The R9 M265X's nearest rivals include the AMD Radeon Pro WX 5100 (8863, a 0.1% advantage), the AMD Radeon 550X (8918, a 0.8% advantage), and the NVIDIA GeForce RTX 3050 A Mobile (8746, a 1.2% deficit).

The 10.8% delta between the two cards is substantial when contextualized against these rival clusters. The FirePro W5000 is effectively swapping places with high-end NVIDIA workstation and gaming cards from a later era, while the R9 M265X trades blows with lower-tier professional and mobile parts. The performance separation is consistent with the hardware specifications: the FirePro W5000 carries 768 shading units versus 640 on the R9 M265X, and its 32 ROPs double the R9 M265X's 16. Those differences manifest directly in the measured compute output.

Where Each One Wins

The database records exactly one benchmark between these two cards, and the AMD FirePro W5000 wins it outright. There are no recorded tests where the AMD Radeon R9 M265X takes the lead. For users interested in OpenCL compute workloads, which is the only metric captured, the FirePro W5000 is the clear choice.

The FirePro W5000's advantage is most pronounced in scenarios that stress raw throughput. Its 1,267.2 GFLOPS FP32 performance exceeds the R9 M265X's 800.0 GFLOPS by a wide margin, translating directly to the 10.8% benchmark gap. The texture rate tells a similar story: 39.60 GTexel/s versus 25.00 GTexel/s. The pixel rate is where the gap becomes extreme: 26.40 GPixel/s versus 10.00 GPixel/s, a 164% advantage for the FirePro W5000. That pixel throughput difference is driven by the ROP count (32 versus 16) and the memory subsystem.

The R9 M265X does not win any recorded benchmark. Its lower transistor count (1,500 million versus 2,800 million) and smaller die (123 mm² versus 212 mm²) place it firmly behind the FirePro W5000 in every measured dimension. The only area where the R9 M265X shows any comparative strength is clock speed, with a 575 MHz base and 625 MHz boost, but those higher clocks cannot compensate for fewer execution units, half the ROPs, and a narrower memory bus.

Architecture Differences

Both GPUs are built on GCN 1.0 architecture, fabricated by TSMC on a 28 nm process node. This common foundation means the architectural feature set is identical across both cards: both support DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The fundamental difference lies in the physical implementation.

The FirePro W5000 uses a larger Pitcairn chip with 2,800 million transistors on a 212 mm² die, yielding a transistor density of 13.2 million per mm². The R9 M265X uses the smaller Venus chip with 1,500 million transistors on a 123 mm² die, for a density of 12.2 million per mm². The FirePro's chip is both larger and denser, providing more room for execution resources.

The execution configuration diverges significantly. The FirePro W5000 packs 768 shading units, 48 texture mapping units, and 32 ROPs. The R9 M265X offers 640 shading units, 40 TMUs, and just 16 ROPs. The FirePro W5000 thus has 20% more shading units, 20% more TMUs, and double the ROPs. These resource counts drive the performance separation.

Memory architecture is another major point of divergence. The FirePro W5000 uses a 256-bit memory bus with GDDR5 running at an effective 3.2 Gbps, producing 102.4 GB/s of bandwidth. The R9 M265X narrows the bus to 128-bit with GDDR5 at an effective 4 Gbps, yielding 64.00 GB/s. Despite the R9 M265X's higher memory clock, the FirePro W5000 delivers 60% more bandwidth thanks to the wider bus. Both cards carry 2 GB of GDDR5 memory.

The memory clock figures differ: the FirePro W5000's memory runs at 800 MHz (3.2 Gbps effective), while the R9 M265X's memory runs at 1000 MHz (4 Gbps effective). The R9 M265X also has recorded base and boost clocks of 575 MHz and 625 MHz, while the FirePro W5000's core clocks are not recorded in the database.

The two cards share several specifications: both are PCIe 3.0 x16, both have 2 GB GDDR5 memory, both use 28 nm TSMC fabrication, and both support the same API feature levels. The R9 M265X is a mobile-oriented part with no recorded power, size, or display output data, while the FirePro W5000 is a desktop workstation card with full physical specifications recorded.

The Verdict

The data makes the choice straightforward for compute-oriented workloads. The AMD FirePro W5000 outperforms the AMD Radeon R9 M265X by 10.8% in the only recorded benchmark, Geekbench OpenCL. That margin is consistent across every hardware specification that predicts compute performance: the FirePro W5000 has more shading units, more TMUs, double the ROPs, wider memory bus, and higher FP32 throughput.

For users prioritizing rasterization workloads, the pixel rate difference is the most telling statistic. The FirePro W5000's 26.40 GPixel/s versus the R9 M265X's 10.00 GPixel/s represents a 164% advantage. This stems from the ROP count difference and the memory bandwidth gap. Any workload that depends on pixel fill rate will favor the FirePro W5000 overwhelmingly.

The R9 M265X does have some qualitative advantages from the recorded data. It was released later (2014 versus 2012), and its smaller die (123 mm² versus 212 mm²) suggests lower manufacturing cost and power draw, though no TDP is recorded for the R9 M265X. Its higher memory clock (4 Gbps effective versus 3.2 Gbps) shows an attempt to compensate for the narrower bus, but the measured bandwidth tells the actual story: 64.00 GB/s versus 102.4 GB/s.

The percentile rankings reinforce the verdict. The FirePro W5000 ranks at the 47th percentile of all GPUs, placing it near the NVIDIA GeForce GTX 1070 (9780, 0.2% behind) and NVIDIA Quadro M2000M (9832, 0.3% ahead). The R9 M265X ranks at the 44th percentile, aligning with the AMD Radeon Pro WX 5100 (8863, 0.1% ahead) and AMD Radeon 550X (8918, 0.8% ahead). These clusters place the FirePro W5000 in a clearly higher performance bracket.

Buyers selecting a GPU for OpenCL compute or pixel-heavy rendering should choose the AMD FirePro W5000 without hesitation based on the recorded measurements. The R9 M265X is appropriate only where the smaller physical footprint and later release date matter more than performance, but the database contains no benchmark where it wins. The FirePro W5000's launch MSRP was 599 USD, and it is now an end-of-life product, as is the R9 M265X. Both cards are legacy parts, but the FirePro W5000 remains the stronger performer in every measured dimension.
