Both GPUs share the same fundamental architecture: RDNA 1.0 on the Navi 14 chip, fabricated by TSMC on a 7 nm process. The transistor count is identical at 6,400 million, and the die size matches at 158 mm², giving both a transistor density of 40.5M per mm². Neither GPU includes ray tracing cores or tensor cores, and both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

The Radeon Pro 5500 XT belongs to the Radeon Pro Mac (Navi Series) generation and is classified as an IGP with no display outputs. The Radeon RX 5300M belongs to the Navi Mobile (RX 5000M) series and has portable device dependent display outputs. The RX 5300M lists its predecessor as Polaris Mobile, while the Pro 5500 XT has no recorded predecessor or successor.

Clock behavior differs significantly. The Pro 5500 XT runs a base clock of 1187 MHz and a boost clock of 1757 MHz, with no game clock specified. The RX 5300M runs a lower base clock of 1000 MHz and boost clock of 1445 MHz, but it has a defined game clock of 1181 MHz. Memory clocks match at 1750 MHz with 14 Gbps effective speed for both.

The RX 5300M is a mobile part with a power draw of 85 W, while the Pro 5500 XT draws 125 W. The Pro 5500 XT suggests a 300 W PSU, whereas the RX 5300M has no suggested PSU listed. Both use PCIe 4.0 x8 and have no power connectors. Release timing places the RX 5300M in November 2019 and the Pro 5500 XT in August 2020, with both marked as end-of-life.

Where Each One Wins

The Radeon Pro 5500 XT wins the only direct benchmark comparison, taking the Geekbench OpenCL test by a margin of 14.4%. Its average score of 45384 versus 36529 represents a substantial gap of roughly 24% in overall compute performance. The Pro 5500 XT also holds a higher percentile ranking at 84th versus 80th among all GPUs.

The RX 5300M has no benchmark wins in the head-to-head data. However, its lower 85 W power draw makes it the more efficient choice for portable implementations, and its 3 GB memory configuration targets lighter workloads where the smaller frame buffer is sufficient. The RX 5300M's nearest rival alignment shows it sits close to desktop-class GPUs from the previous generation, with a 0% delta against the NVIDIA GeForce GTX TITAN X and only 1.9% behind the AMD Radeon Pro Duo.

The Pro 5500 XT's nearest rival comparison shows it competing with modern high-end parts: it trails the Intel Arc A730M by just 0.5%, leads the NVIDIA GeForce RTX 5090 Mobile by 0.5%, trails the NVIDIA RTX 5880 Ada Generation by 1.3%, and leads the NVIDIA GeForce RTX 4070 Ti by 1.3%. This indicates the Pro 5500 XT sits in a much higher performance tier than the RX 5300M, which aligns with its larger memory bus, more shading units, and higher clock speeds.

For users prioritizing raw compute in OpenCL workloads, the Pro 5500 XT is the clear winner. For scenarios where power draw matters more than peak performance, the RX 5300M's 85 W design point offers a lighter load on mobile thermal solutions, though the data does not include efficiency benchmarks to quantify that trade-off.

Specification Differences

The two GPUs differ across nearly every specification except the chip-level fundamentals. Both use Navi 14 on 7 nm with identical transistor counts and die size, but their configurations diverge from there.

Memory is a major differentiator. The Pro 5500 XT has 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth. The RX 5300M has 3 GB of GDDR6 on a 96-bit bus, delivering 168.0 GB/s. That is a 56 GB/s bandwidth advantage for the Pro 5500 XT, plus a 5 GB capacity advantage.

Compute resources scale similarly. The Pro 5500 XT has 1536 shading units, 96 TMUs, and 32 ROPs. The RX 5300M has 1408 shading units, 88 TMUs, and 32 ROPs. Pixel rate reflects this: 56.22 GPixel/s for the Pro 5500 XT versus 46.24 GPixel/s for the RX 5300M. Texture rate is 168.7 GTexel/s versus 127.2 GTexel/s. FP32 compute is 5.398 TFLOPS versus 4.069 TFLOPS, and FP16 is 10.80 TFLOPS versus 8.138 TFLOPS, both at a 2:1 ratio.

Clock speeds differ across the board. The Pro 5500 XT has a base clock of 1187 MHz and boost of 1757 MHz. The RX 5300M has a base clock of 1000 MHz, boost of 1445 MHz, and game clock of 1181 MHz. Power draw is 125 W for the Pro 5500 XT versus 85 W for the RX 5300M. The Pro 5500 XT lists a suggested PSU of 300 W; the RX 5300M has none. The Pro 5500 XT is an IGP with no display outputs; the RX 5300M has portable device dependent outputs. Release dates differ by roughly nine months, with the RX 5300M arriving in November 2019 and the Pro 5500 XT in August 2020.

Head-to-Head Benchmarks

The database records one head-to-head benchmark between these two GPUs: Geekbench OpenCL. The Radeon Pro 5500 XT scores 41772, while the Radeon RX 5300M scores 36529. The delta is 14.4% in favor of the Pro 5500 XT.

This single result aligns with the broader specification gap. The Pro 5500 XT's 32.7% higher FP32 throughput (5.398 TFLOPS versus 4.069 TFLOPS) and 33.3% higher texture rate (168.7 GTexel/s versus 127.2 GTexel/s) translate into a 14.4% OpenCL advantage, suggesting that memory bandwidth constraints or other bottlenecks moderate the raw compute lead.

The average benchmark scores amplify the difference. The Pro 5500 XT averages 45384 across three tests (Geekbench Metal at 54779, OpenCL at 41772, and Vulkan at 39601), while the RX 5300M has only one recorded benchmark, the OpenCL result of 36529. The Pro 5500 XT's best result, Geekbench Metal at 54779, exceeds the RX 5300M's entire average by 50%. Even the Pro 5500 XT's weakest result, Vulkan at 39601, beats the RX 5300M's OpenCL score by 8.4%.

The Pro 5500 XT's nearest rival data reinforces its position. It sits within 1.3% of the NVIDIA RTX 5880 Ada Generation and within 0.5% of the Intel Arc A730M and NVIDIA GeForce RTX 5090 Mobile. The RX 5300M, by contrast, sits within 1.9% of the AMD Radeon Pro Duo and matches the NVIDIA GeForce GTX TITAN X exactly at 0% delta. These positioning gaps show the Pro 5500 XT competing with modern high-end mobile and workstation parts, while the RX 5300M aligns with older desktop flagships.

The wins tally is 1 for the Pro 5500 XT and 0 for the RX 5300M in direct comparisons. The data does not include any test where the RX 5300M outperforms the Pro 5500 XT.

The Verdict

The Radeon Pro 5500 XT is the superior GPU in every measured benchmark. Its average score of 45384 places it 24% above the RX 5300M's 36529, and its 84th percentile ranking versus 80th confirms a higher tier of overall performance. The 14.4% OpenCL lead in the direct head-to-head is consistent with the Pro 5500 XT's larger memory bus, higher clock speeds, and greater compute resources.

Choose the Radeon Pro 5500 XT for workloads that demand compute throughput: OpenCL, Vulkan, and Metal applications where the 8 GB frame buffer and 224.0 GB/s bandwidth provide headroom. Its nearest rivals include the NVIDIA RTX 5880 Ada Generation and Intel Arc A730M, which places it in serious workstation territory. The 125 W power draw is modest for the performance class, though it is not a mobile-optimized part.

Choose the Radeon RX 5300M for constrained mobile implementations where the 85 W power draw is the primary constraint. Its 3 GB memory and 168.0 GB/s bandwidth are sufficient for lighter rendering tasks, and its performance aligns with the NVIDIA GeForce GTX TITAN X and AMD Radeon Pro Duo. The RX 5300M offers no benchmark wins over the Pro 5500 XT, but its lower power envelope and portable device dependent outputs make it the only one of the two suited to thin-and-light laptops.

The Pro 5500 XT is the all-around pick for compute performance. The RX 5300M is the pick only when power limits override performance needs. The recorded data provides no scenario where the RX 5300M wins a performance comparison, and its single benchmark result leaves its broader capabilities less characterized than the Pro 5500 XT's three-test record. Both GPUs are end-of-life, so availability and platform support, not performance, will likely decide between them in practice.
