AMD Radeon Pro 5300M vs NVIDIA Quadro 6000 Comparison

The AMD Radeon Pro 5300M and NVIDIA Quadro 6000 represent two very different eras of professional graphics, and the benchmark data reflects a decisive generational gap. The Radeon Pro 5300M is the clear winner in the only shared test, delivering nearly triple the OpenCL performance of the Quadro 6000. However, the Quadro 6000, with its larger memory pool and legacy feature set, still holds relevance in specific workstation scenarios where capacity outweighs raw compute speed.

Where Each One Wins

The AMD Radeon Pro 5300M wins decisively in raw computational throughput. In the sole head-to-head benchmark available—Geekbench OpenCL—the Radeon Pro 5300M scores 29,252 against the Quadro 6000’s 9,846. This translates to a 197.1% delta, meaning the AMD card is nearly three times faster in this compute-oriented workload. The Radeon Pro 5300M also holds a wider range of benchmark data, including strong showings in Geekbench Metal (33,626) and Vulkan (27,912), which are absent from the Quadro 6000’s records entirely.

The NVIDIA Quadro 6000 wins in the memory capacity and legacy compatibility categories. It offers 6 GB of GDDR5 memory versus the AMD card’s 4 GB of GDDR6, a 50% advantage in frame buffer size. This makes the Quadro 6000 better suited for workloads that require holding large datasets in video memory, such as certain rendering scenes or compute buffers that exceed 4 GB. The Quadro 6000 also has a wider 384-bit memory bus, although its total bandwidth (143.4 GB/s) is lower than the Radeon’s 192.0 GB/s due to slower memory clocks. For older professional software that relies on NVIDIA’s legacy Fermi architecture features, the Quadro 6000 provides a compatibility path that the newer RDNA-based card cannot.

Architecture Differences

The architectural gap between these two cards is vast and explains the performance disparity. The AMD Radeon Pro 5300M is built on the Navi 14 chip using the RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. This modern node packs 6,400 million transistors into a 158 mm² die, achieving a transistor density of 40.5M per mm². The NVIDIA Quadro 6000, in contrast, uses the GF100 chip with the Fermi architecture, produced on a 40 nm process. Its 3,100 million transistors occupy a much larger 529 mm² die, resulting in a density of only 5.9M per mm². The Radeon’s process advantage allows it to house 1,280 shading units, 80 texture mapping units, and 32 ROPs, while the Quadro 6000 offers just 448 shading units, 56 TMUs, and 48 ROPs.

The Radeon Pro 5300M features 1280 shading units and supports FP16 compute at 6.400 TFLOPS with a 2:1 ratio, while the Quadro 6000 has no FP16 capability listed. The Radeon’s FP32 throughput is 3.200 TFLOPS, more than triple the Quadro’s 1,027.7 GFLOPS. The memory subsystems differ fundamentally: the Radeon uses 4 GB of GDDR6 on a 128-bit bus with 192.0 GB/s bandwidth, while the Quadro uses 6 GB of GDDR5 on a 384-bit bus with 143.4 GB/s bandwidth. The Radeon also supports PCIe 4.0 x8, whereas the Quadro uses PCIe 2.0 x16. In terms of API support, the Radeon offers DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4; the Quadro offers DirectX 12 (11_0) and OpenGL 4.6 but has no Vulkan support listed.

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and the result is lopsided. The AMD Radeon Pro 5300M scores 29,252, while the NVIDIA Quadro 6000 scores 9,846. This 197.1% delta means the AMD card is almost exactly three times faster in this test. This massive margin is consistent with the architectural differences—the Radeon’s newer 7 nm node, higher shading unit count, and significantly faster memory bandwidth all contribute to its dominance in compute tasks. The Quadro’s 1,027.7 GFLOPS FP32 rate is simply insufficient to compete with the Radeon’s 3.200 TFLOPS.

Outside the head-to-head, the Radeon Pro 5300M shows strong performance across other APIs. Its Geekbench Metal score of 33,626 and Vulkan score of 27,912 indicate that it handles modern graphics APIs efficiently. The Quadro 6000 has no recorded scores for those tests in the fact pack. The Radeon also has a Passmark G3D score of 5,918 and a G2D score of 582, while the Quadro lacks these entries. However, the Radeon’s Passmark DirectX scores are low—36 for DX10, 37 for DX11, 25 for DX12, and 80 for DX9—suggesting that its strengths lie in compute and modern API workloads rather than legacy DirectX rasterization.

Specification Differences

The two cards differ on nearly every measurable specification. The process node is a major divider: 7 nm for the Radeon versus 40 nm for the Quadro. Transistor counts are 6,400 million versus 3,100 million, and die sizes are 158 mm² versus 529 mm². The Radeon has a base clock of 1000 MHz and a boost clock of 1250 MHz, while the Quadro has no listed base or boost clocks. Memory clocks are 1500 MHz (12 Gbps effective) for the Radeon versus 747 MHz (3 Gbps effective) for the Quadro.

Memory capacity is 4 GB GDDR6 versus 6 GB GDDR5. Bus widths are 128-bit versus 384-bit. Bandwidth is 192.0 GB/s versus 143.4 GB/s. Shading units are 1,280 versus 448. TMUs are 80 versus 56. ROPs are 32 versus 48. Pixel rates are 40.00 GPixel/s versus 16.07 GPixel/s. Texture rates are 100.0 GTexel/s versus 32.14 GTexel/s. FP32 performance is 3.200 TFLOPS versus 1,027.7 GFLOPS. FP16 is 6.400 TFLOPS for the Radeon, with no listing for the Quadro.

Power consumption differs dramatically: 85 W for the Radeon versus 204 W for the Quadro. The Radeon uses no power connectors, while the Quadro requires 1x 6-pin and 1x 8-pin connectors with a suggested 550 W PSU. The Radeon is a mobile card with portable device-dependent display outputs, while the Quadro is a dual-slot desktop card measuring 248 mm in length, 111 mm in height, with outputs of 1x DVI, 2x DisplayPort, and 1x S-Video. The Radeon uses PCIe 4.0 x8; the Quadro uses PCIe 2.0 x16. The Radeon’s release date is 2019-11-12, while the Quadro’s is 2010-12-09.

The Verdict

The data is unambiguous: the AMD Radeon Pro 5300M is the superior card for modern compute workloads. Its 197.1% lead in Geekbench OpenCL, combined with its support for Metal, Vulkan, and FP16 processing, makes it the obvious choice for any application that leverages contemporary APIs or requires high throughput. The Radeon’s 3.200 TFLOPS FP32 and 6.400 TFLOPS FP16 performance dwarfs the Quadro’s 1,027.7 GFLOPS FP32, and its 7 nm process delivers this performance at less than half the power draw (85 W versus 204 W). The Radeon also fits in a power-constrained mobile form factor, whereas the Quadro is a dual-slot desktop card requiring external power.

The NVIDIA Quadro 6000 retains a niche for users who specifically need more than 4 GB of video memory. Its 6 GB GDDR5 frame buffer is 50% larger than the Radeon’s 4 GB, which can be critical for certain large-buffer rendering or compute tasks. Additionally, its 384-bit memory bus offers a wider path for data, even if total bandwidth is lower. For legacy software that predates modern APIs or relies on Fermi-era NVIDIA features, the Quadro 6000 provides compatibility that the Radeon cannot match. However, given its lower average benchmark score (9,846 versus 10,013), near-identical percentile ranking (47th versus 48th), and outdated 40 nm architecture, these advantages are narrow. The data supports choosing the Radeon Pro 5300M for nearly all applications, reserving the Quadro 6000 for specific memory-bound legacy workflows where its larger frame buffer is essential.
