AMD Radeon Pro WX 7100 vs AMD Radeon RX 5300M Comparison

The AMD Radeon Pro WX 7100 and the AMD Radeon RX 5300M are two very different GPUs separated by three years of architecture evolution and intended for different segments of the market. The data shows a head-to-head comparison that is surprisingly narrow in scope, with only one common benchmark test recorded, yet the underlying specifications reveal a stark contrast in design philosophy. The WX 7100, a professional workstation card from 2016, relies on a wider memory bus and a larger chip, while the RX 5300M, a mobile gaming part from 2019, leverages a more advanced process node and higher clock speeds to achieve efficiency. This analysis walks through the available benchmark data, architectural differences, and use-case scenarios strictly based on the provided facts.

Head-to-Head Benchmarks

The only direct benchmark comparison available between these two GPUs is the Geekbench OpenCL test. In this test, the AMD Radeon Pro WX 7100 scores 40,148 points, while the AMD Radeon RX 5300M scores 36,529 points. The WX 7100 wins this round with a delta of 9.9% over the RX 5300M. This is a significant margin, indicating that in raw compute workloads utilizing OpenCL, the older professional card holds a clear advantage. The win count in the head-to-head section confirms this, with the WX 7100 taking 1 win and the RX 5300M taking 0.

Contextualizing this score, the WX 7100’s average benchmark score of 40,063 places it at the 82nd percentile of all GPUs, while the RX 5300M’s average of 36,529 places it at the 80th percentile. Despite the 9.9% delta in the direct test, their overall standing among all GPUs is quite close, separated by just two percentile points. Looking at the nearest rivals for the WX 7100, its OpenCL score is marginally ahead of the NVIDIA RTX A500 Mobile (1.3% delta) and the AMD Radeon Pro 575 (1.3% delta), but it trails the AMD Radeon Pro 580 (-0.6%) and the NVIDIA GeForce RTX 5070 (-0.8%). For the RX 5300M, its score is essentially tied with the NVIDIA GeForce GTX TITAN X (0% delta), slightly ahead of the NVIDIA T1000 (0.7% delta) and the AMD Radeon Pro Duo (1.9% delta), but behind the AMD Radeon PRO W6400 (-1.7% delta). The benchmark data suggests that while the WX 7100 is faster in this specific test, the RX 5300M is competing in a similar performance tier, just slightly lower.

Architecture Differences

The two cards are built on fundamentally different architectures and process nodes. The AMD Radeon Pro WX 7100 uses the Ellesmere chip, based on the GCN 4.0 architecture, and is fabricated on a 14 nm process at GlobalFoundries. In contrast, the AMD Radeon RX 5300M uses the Navi 14 chip, based on the RDNA 1.0 architecture, and is fabricated on a more advanced 7 nm process at TSMC. This process advantage is significant, allowing the RX 5300M to pack more transistors into a smaller die. The RX 5300M has 6,400 million transistors on a 158 mm² die, resulting in a transistor density of 40.5M / mm². The WX 7100 has 5,700 million transistors on a larger 232 mm² die, yielding a lower density of 24.6M / mm². This means the RX 5300M is a much more tightly packed and efficient chip.

The memory subsystems are also completely different. The WX 7100 uses 8 GB of GDDR5 memory on a 256-bit bus, delivering a bandwidth of 224.0 GB/s. The RX 5300M uses only 3 GB of GDDR6 memory on a 96-bit bus, providing 168.0 GB/s of bandwidth. While the newer GDDR6 memory is faster per pin (14 Gbps effective vs 7 Gbps effective), the narrower bus on the RX 5300M limits its total bandwidth. The WX 7100’s wider bus gives it a 33% bandwidth advantage, which is critical for high-resolution texture work and compute tasks. The RX 5300M does have a higher boost clock of 1445 MHz versus 1243 MHz on the WX 7100, and it also lists a game clock of 1181 MHz, which the WX 7100 does not have. The shading unit counts also differ, with the WX 7100 featuring 2304 shading units, 144 TMUs, and 32 ROPs, while the RX 5300M has 1408 shading units, 88 TMUs, and 32 ROPs. The WX 7100’s larger number of execution units compensates for its lower clock speeds.

Where Each One Wins

Based on the data, the AMD Radeon Pro WX 7100 wins in the single recorded compute benchmark, the Geekbench OpenCL test, with a 9.9% lead. Its strengths lie in its massive memory bandwidth of 224.0 GB/s and its high FP32 throughput of 5.728 TFLOPS. The WX 7100 also features four DisplayPort 1.4a outputs, making it suitable for multi-monitor professional setups. It has a higher pixel rate of 39.78 GPixel/s and a much higher texture rate of 179.0 GTexel/s compared to the RX 5300M’s 127.2 GTexel/s. The WX 7100 also supports 4 GB more memory, which is a substantial advantage for large datasets.

The AMD Radeon RX 5300M wins in the efficiency and feature-set categories. Its 85 W TDP is significantly lower than the WX 7100's 130 W, and it requires no power connectors, whereas the WX 7100 requires a single 6-pin connector. The RX 5300M is built for portable devices, with its display outputs listed as "Portable Device Dependent." It also supports a newer DirectX version (12_1 vs 12_0) and a newer Vulkan version (1.4 vs 1.3). The RX 5300M’s FP16 performance is notably double its FP32 rate at 8.138 TFLOPS, indicating a 2:1 ratio, whereas the WX 7100 has a 1:1 ratio at 5.728 TFLOPS. The RX 5300M also has a higher boost clock and benefits from PCIe 4.0 x8, while the WX 7100 is limited to PCIe 3.0 x16.

The Verdict

The data presents a clear split between these two GPUs. The AMD Radeon Pro WX 7100 is the choice for compute-heavy professional workloads where memory capacity and bandwidth are paramount. Its 8 GB of memory, 224.0 GB/s bandwidth, and 5.728 TFLOPS of FP32 performance directly support its 9.9% lead in the OpenCL benchmark. Its 82nd percentile standing and close rivalry with cards like the NVIDIA RTX A500 Mobile and AMD Radeon Pro 575 position it as a capable workstation solution. The WX 7100 is a single-slot card designed for a desktop workstation environment, with four DisplayPort outputs for multi-monitor arrays. Its end-of-life status and 2016 release date, however, indicate it is a legacy part.

The AMD Radeon RX 5300M is the better option for a mobile, power-constrained environment. Its 85 W TDP, lack of power connectors, and portable-device-dependent outputs clearly mark it as a laptop GPU. While it loses the compute benchmark, its 7 nm process, higher boost clock of 1445 MHz, and doubled FP16 performance of 8.138 TFLOPS show a modern architecture focused on efficiency and specific accelerated tasks. Its 80th percentile standing, nearly tied with the NVIDIA GeForce GTX TITAN X, shows it holds its own in the broader GPU landscape. Users who require maximum compute performance and memory for professional applications should look to the WX 7100, while those needing a lower-power, more modern mobile solution with faster memory clocks should consider the RX 5300M. The choice is not about which is universally better, but which set of trade-offs fits the intended use case.
