AMD Radeon Pro 5300 vs NVIDIA GeForce RTX 5080 Mobile Comparison

# AMD Radeon Pro 5300 vs NVIDIA GeForce RTX 5080 Mobile

The benchmark data presents a decisive comparison between two mobile graphics processors from different eras: the AMD Radeon Pro 5300, an end-of-life RDNA 1.0 part from 2020, and the NVIDIA GeForce RTX 5080 Mobile, an active Blackwell 2.0 part from 2025. Across the two shared benchmark tests, the NVIDIA GPU wins both, with margins exceeding 76% in each case. The Radeon Pro 5300 holds a 82nd percentile ranking among all GPUs, while the RTX 5080 Mobile sits at the 81st percentile, yet the raw score gap between them is substantial, suggesting the older AMD part's percentile is buoyed by a narrower benchmark suite.

Where Each One Wins

The head-to-head data is unambiguous: the NVIDIA GeForce RTX 5080 Mobile wins every shared benchmark. In Geekbench OpenCL, the RTX 5080 Mobile scores 166,986 against the Radeon Pro 5300's 38,747, a delta of -76.8% from the AMD part's perspective. In Geekbench Vulkan, the NVIDIA GPU scores 169,754 versus 35,793, a -78.9% delta. There is no benchmark in the shared set where the AMD Radeon Pro 5300 comes out ahead; the wins tally is 0 for AMD and 2 for NVIDIA.

However, the Radeon Pro 5300 does have its own benchmark strengths when viewed in isolation. Its Geekbench Metal score of 48,070 is its highest across the three tests it runs, and its average benchmark score of 40,870 places it within 0.8% of the NVIDIA GeForce RTX 3080 Ti's 41,187 average. The RTX 5080 Mobile, by contrast, shows a broader spread: its PassMark G3D score of 27,711 is strong, but its PassMark DirectX 12 score of 116 is remarkably low relative to its other results, indicating that synthetic API-specific tests can produce outliers.

For use-case segmentation, the data suggests the RTX 5080 Mobile is the choice for compute-heavy or Vulkan-accelerated workloads, where its scores are 4.3x and 4.7x higher respectively. The Radeon Pro 5300, with its Metal-focused performance, may still serve legacy macOS-oriented tasks, but no benchmark in the pack demonstrates a win for it over the NVIDIA part.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process technologies. The AMD Radeon Pro 5300 uses the Navi 14 chip on RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC with 6,400 million transistors on a 158 mm² die, yielding a transistor density of 40.5 million per mm². The NVIDIA GeForce RTX 5080 Mobile uses the GB203 chip on Blackwell 2.0 architecture, built on a 5 nm process at TSMC with 45,600 million transistors on a 378 mm² die, achieving a transistor density of 120.6 million per mm² — roughly three times the density of the AMD part.

Core configurations differ dramatically. The Radeon Pro 5300 has 1,280 shading units, 80 texture mapping units, and 32 raster output pipelines, with no ray tracing or tensor cores listed. The RTX 5080 Mobile has 7,680 shading units, 240 TMUs, and 96 ROPs, plus 60 ray tracing cores and 240 tensor cores. This is a 6x increase in shading units, a 3x increase in TMUs, and a 3x increase in ROPs.

Memory subsystems are also generations apart. The AMD part uses 4 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth, while the NVIDIA part uses 16 GB of GDDR7 on a 256-bit bus with 896.0 GB/s bandwidth — a 4x capacity increase and a 4x bandwidth increase. Clock speeds are closer: the Radeon Pro 5300 runs at 1000 MHz base and 1650 MHz boost, while the RTX 5080 Mobile runs at 975 MHz base and 1500 MHz boost, meaning the AMD part actually has higher clock speeds, but the NVIDIA part's massive core count more than compensates.

Feature support differs as well. The Radeon Pro 5300 supports DirectX 12 (12_1), while the RTX 5080 Mobile supports DirectX 12 Ultimate (12_2). Both support OpenGL 4.6 and Vulkan 1.4. The RTX 5080 Mobile adds ray tracing and tensor core hardware, plus a PCIe 5.0 x16 interface versus the AMD part's PCIe 4.0 x8.

The Verdict

The data leads to a clear conclusion: the NVIDIA GeForce RTX 5080 Mobile is the superior GPU by every shared benchmark measure. Its OpenCL score of 166,986 is 331% higher than the Radeon Pro 5300's 38,747, and its Vulkan score of 169,754 is 374% higher than 35,793. These are not marginal improvements; they represent generational leaps in raw compute capability.

For users choosing between these two, the decision hinges on workload compatibility. If the application relies on Metal — the Radeon Pro 5300's strongest API, where it scores 48,070 — and fits within a 4 GB GDDR6 memory footprint, the AMD part may still function adequately. But for any OpenCL or Vulkan workload, the RTX 5080 Mobile's scores are overwhelming. The NVIDIA part also offers 16 GB of GDDR7 memory versus 4 GB, a 256-bit bus versus 128-bit, and 60 ray tracing cores that the AMD part lacks entirely.

The RTX 5080 Mobile's average benchmark score of 38,349 is actually lower than the Radeon Pro 5300's 40,870, but this is misleading. The NVIDIA part's average is dragged down by low PassMark legacy DirectX scores (116 in DirectX 12, 171 in DirectX 10) that do not reflect its modern API performance. The head-to-head results, which use comparable modern tests, are the more reliable indicator.

FAQ

Head-to-Head Benchmarks

The two shared benchmarks paint a stark picture. In Geekbench OpenCL, the RTX 5080 Mobile's 166,986 dwarfs the Radeon Pro 5300's 38,747. The delta of -76.8% means the AMD part delivers less than a quarter of the NVIDIA GPU's compute throughput in this test. This is consistent with the core count disparity: 7,680 shading units versus 1,280, and 240 TMUs versus 80.

In Geekbench Vulkan, the gap widens slightly. The RTX 5080 Mobile scores 169,754 against 35,793, a -78.9% delta. Vulkan's lower-level API overhead may favor the newer architecture, and the RTX 5080 Mobile's PCIe 5.0 x16 interface versus the Radeon Pro 5300's PCIe 4.0 x8 could also contribute to the larger margin.

The Radeon Pro 5300's best result, Geekbench Metal at 48,070, is not part of the head-to-head set because the RTX 5080 Mobile does not have a Metal benchmark listed. Similarly, the RTX 5080 Mobile's PassMark G3D score of 27,711 and its 3DMark Steel Nomad DX12 score of 4,952 have no AMD counterpart in the pack. This limits direct comparison to OpenCL and Vulkan, but those two tests are sufficient to establish the NVIDIA GPU's dominance.

Specification Differences

The specification sheets reveal a generational chasm. The AMD Radeon Pro 5300 uses a 7 nm process, while the NVIDIA GeForce RTX 5080 Mobile uses a 5 nm process, both at TSMC. Transistor counts are 6,400 million versus 45,600 million, and die sizes are 158 mm² versus 378 mm². Transistor density is 40.5 million per mm² for AMD and 120.6 million per mm² for NVIDIA.

Clock speeds slightly favor AMD: 1000 MHz base and 1650 MHz boost versus 975 MHz base and 1500 MHz boost. Memory clocks are identical at 1750 MHz, but the effective data rates differ — 14 Gbps for the Radeon Pro 5300 versus 28 Gbps for the RTX 5080 Mobile. Memory capacity is 4 GB versus 16 GB, bus width is 128-bit versus 256-bit, and bandwidth is 224.0 GB/s versus 896.0 GB/s.

Compute resources are heavily skewed toward NVIDIA: 1,280 shading units versus 7,680, 80 TMUs versus 240, 32 ROPs versus 96. The RTX 5080 Mobile adds 60 RT cores and 240 tensor cores, while the Radeon Pro 5300 has none. Pixel rate is 52.80 GPixel/s versus 144.0 GPixel/s, and texture rate is 132.0 GTexel/s versus 360.0 GTexel/s. FP32 performance is 4.224 TFLOPS versus 23.04 TFLOPS, and FP16 is 8.448 TFLOPS (2:1) versus 23.04 TFLOPS (1:1).

Power draw is similar: 85 W for the AMD part and 80 W for the NVIDIA part, both with no power connectors and IGP slot width. The bus interface differs — PCIe 4.0 x8 for AMD versus PCIe 5.0 x16 for NVIDIA. The AMD part has no display outputs, while the NVIDIA part is portable device dependent. DirectX support is 12 (12_1) for AMD versus 12 Ultimate (12_2) for NVIDIA, with both supporting OpenGL 4.6 and Vulkan 1.4. The suggested PSU is 250 W for AMD, while NVIDIA lists none.
