Architecture Differences

The architectural gap between these two GPUs is substantial, reflecting nearly six years of semiconductor advancement. The AMD Radeon RX 5300M is built on RDNA 1.0, AMD's first-generation RDNA architecture, fabricated on a 7 nm TSMC process. The chip, Navi 14, contains 6,400 million transistors on a 158 mm² die, yielding a transistor density of 40.5M per mm². The NVIDIA RTX PRO 4500 Blackwell uses the Blackwell 2.0 architecture on a 5 nm TSMC process. Its GB203 chip packs 45,600 million transistors on a 378 mm² die, achieving a transistor density of 120.6M per mm², roughly three times denser than the AMD part.

Memory architecture differs fundamentally. The RX 5300M uses 3 GB of GDDR6 with a 96-bit bus, delivering 168.0 GB/s. The RTX PRO 4500 uses 32 GB of GDDR7 with a 256-bit bus, delivering 896.0 GB/s. The effective memory clock for the AMD card is 14 Gbps, while the NVIDIA card runs at 28 Gbps effective. This memory advantage directly impacts bandwidth-bound workloads.

Compute resources diverge dramatically. The RX 5300M has 1,408 shading units, 88 TMUs, and 32 ROPs. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, and 112 ROPs. The NVIDIA card also includes dedicated ray tracing cores (82) and tensor cores (328), neither of which exist on the AMD card. The FP32 throughput tells the story: 4.069 TFLOPS for AMD versus 50.53 TFLOPS for NVIDIA, a 12.4x difference. The FP16 ratio also differs, with AMD at 8.138 TFLOPS (2:1 ratio) and NVIDIA at 50.53 TFLOPS (1:1 ratio).

The bus interface also separates the two. The RX 5300M uses PCIe 4.0 x8, while the RTX PRO 4500 uses PCIe 5.0 x16, offering substantially more host bandwidth. Display outputs on the AMD card are portable device dependent, whereas the NVIDIA card offers 4x DisplayPort 2.1b. Manufacturing status differs as well: the RX 5300M is end-of-life, while the RTX PRO 4500 is active production.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs, and the win count stands at zero for each. However, the individual benchmark suites reveal distinct performance profiles. The RX 5300M's sole recorded benchmark is Geekbench OpenCL, where it scores 36,529. This places it in the 80th percentile of all GPUs in the database.

The RTX PRO 4500 has a broader benchmark portfolio. Its Geekbench Vulkan score is 221,768, which is exceptionally high and reflects strong compute capability in Vulkan workloads. In PassMark G3D, the NVIDIA card scores 33,360, and in PassMark GPU Compute it scores 19,255. The DirectX legacy tests show lower numbers: PassMark DirectX 9 at 397, DirectX 10 at 204, DirectX 11 at 320, and DirectX 12 at 119. The PassMark G2D score is 1,336.

The average benchmark score for the RTX PRO 4500 is 31,532, which is lower than the RX 5300M's 36,529. This is partly because the NVIDIA card's average includes its low DirectX 9 through 12 legacy scores, which drag down the aggregate. The RX 5300M's single OpenCL score, by contrast, is uniformly high. The percentile ranking reflects this: the RX 5300M sits at the 80th percentile, while the RTX PRO 4500 sits at the 76th percentile.

Rival comparisons from the database provide context. The RX 5300M's nearest rival is the NVIDIA GeForce GTX TITAN X with a score of 36,530, a delta of 0%. The AMD Radeon PRO W6400 scores 37,157, putting the RX 5300M 1.7% behind. The NVIDIA T1000 scores 36,289, putting the RX 5300M 0.7% ahead. The AMD Radeon Pro Duo scores 35,860, with the RX 5300M 1.9% ahead.

For the RTX PRO 4500, the nearest rival is the NVIDIA TITAN RTX at 31,676, a delta of -0.5%, meaning the RTX PRO 4500 trails by half a percent. The NVIDIA GRID M60-1Q scores 31,220, with the RTX PRO 4500 1% ahead. The NVIDIA Quadro M5000 scores 31,206, also 1% ahead. The Intel Arc Pro A30M scores 31,894, with the RTX PRO 4500 1.1% behind.

The Verdict

The data presents a clear split. The AMD Radeon RX 5300M is a legacy mobile GPU, end-of-life, designed for portability with a low 85 W TDP and no power connectors. Its single OpenCL benchmark score of 36,529 and 80th percentile ranking show it remains competitive in compute-oriented tests, but its hardware is dated: RDNA 1.0, 3 GB memory, no ray tracing, no tensor cores, and PCIe 4.0 x8.

The NVIDIA RTX PRO 4500 Blackwell is a modern workstation-class GPU with a 200 W TDP, dual-slot design, and 32 GB of GDDR7 memory. Its 50.53 TFLOPS FP32 throughput is 12.4x that of the AMD card, and it supports DirectX 12 Ultimate, ray tracing, and tensor cores. Its average benchmark score of 31,532 is lower than the AMD card's, but this is skewed by low legacy DirectX scores. The RTX PRO 4500's PassMark G3D score of 33,360 and Geekbench Vulkan score of 221,768 indicate robust modern workload performance.

For users whose primary metric is the Geekbench OpenCL score, the RX 5300M appears stronger. For users needing modern features, large memory capacity, high bandwidth, or advanced DirectX support, the RTX PRO 4500 is the only choice from the data. The RTX PRO 4500's 76th percentile ranking, despite being dragged down by legacy tests, still places it in the upper quartile of all GPUs.

Where Each One Wins

The AMD Radeon RX 5300M wins in aggregate benchmark score, with 36,529 versus 31,532, a 15.8% advantage. It also holds a higher percentile ranking at 80 versus 76. The database shows its nearest rivals are all within 2% of its score, indicating tight competition in its performance class. Its low TDP of 85 W and lack of power connectors make it suitable for thin-and-light portable devices, as the display outputs are portable device dependent.

The NVIDIA RTX PRO 4500 Blackwell wins decisively in raw compute specifications. It has 7.4x the shading units, 3.7x the TMUs, 3.5x the ROPs, and 12.4x the FP32 throughput. It has 32 GB of memory versus 3 GB, with 5.3x the bandwidth. It adds ray tracing and tensor cores that the AMD card lacks entirely. It supports DirectX 12 Ultimate versus DirectX 12 (12_1). It uses PCIe 5.0 x16 versus PCIe 4.0 x8. It has a higher base clock (1635 MHz versus 1000 MHz) and higher boost clock (2407 MHz versus 1445 MHz).

In terms of DirectX legacy performance, the RTX PRO 4500 shows variable results, with its best legacy score in DirectX 9 (397) and its weakest in DirectX 12 (119). The PassMark G3D score of 33,360 and GPU Compute score of 19,255 demonstrate strength in modern graphics and compute workloads. The Geekbench Vulkan score of 221,768 dwarfs the AMD card's OpenCL score in raw terms, though the tests differ.

The use-case split is clear. The RX 5300M is appropriate for scenarios where power efficiency and portability matter most, and where the workload aligns with OpenCL compute. The RTX PRO 4500 is appropriate for workstation tasks requiring large memory, high bandwidth, ray tracing, tensor operations, or modern DirectX 12 Ultimate features. The data does not support using the RX 5300M for any modern ray-traced or tensor-based workload, as it lacks those hardware units entirely.
