AMD Radeon Pro 5300 vs NVIDIA GeForce RTX 3080 Ti Comparison

The AMD Radeon Pro 5300 and NVIDIA GeForce RTX 3080 Ti occupy the same 83rd percentile of all GPUs, yet their average benchmark scores are nearly identical: the Radeon Pro 5300 posts an average of 41,610 while the RTX 3080 Ti sits at 41,224, a mere 0.9% gap. This statistical tie is deceptive, however, because the two cards achieve parity through wildly different means—the RTX 3080 Ti is a 350 W desktop monster with 10,240 shading units, while the Radeon Pro 5300 is an 85 W integrated mobile-class part with 1,280 shading units. The head-to-head data reveals a one-sided contest in compute workloads, but the average scores suggest the AMD card punches far above its weight in the specific tests it runs.

Specification Differences

The two cards differ in nearly every measurable specification. The RTX 3080 Ti has a base clock of 1365 MHz and boost of 1665 MHz, while the Radeon Pro 5300 runs at 1000 MHz base and 1650 MHz boost. Memory clocks diverge significantly: the RTX 3080 Ti runs at 1188 MHz with 19 Gbps effective, while the Radeon Pro 5300 uses 1750 MHz with 14 Gbps effective.

Memory capacity is a 3x difference: 12 GB versus 4 GB. The bus width differs by 3x as well, with 384-bit on NVIDIA versus 128-bit on AMD. Bandwidth stands at 912.4 GB/s versus 224.0 GB/s. The RTX 3080 Ti has 320 TMUs and 112 ROPs; the Radeon Pro 5300 has 80 TMUs and 32 ROPs.

Pixel rate is 186.5 GPixel/s versus 52.80 GPixel/s, and texture rate is 532.8 GTexel/s versus 132.0 GTexel/s. FP32 compute is 34.10 TFLOPS versus 4.224 TFLOPS. The RTX 3080 Ti delivers FP16 at 34.10 TFLOPS (1:1), while the Radeon Pro 5300 reaches 8.448 TFLOPS (2:1).

The RTX 3080 Ti is a dual-slot card measuring 285 mm long, 112 mm tall, and 40 mm wide. The Radeon Pro 5300 has no listed dimensions and is an IGP (integrated graphics processor) form factor. The RTX 3080 Ti uses PCIe 4.0 x16, while the Radeon Pro 5300 uses PCIe 4.0 x8. Display outputs differ: the RTX 3080 Ti has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the Radeon Pro 5300 has no outputs.

Architecture Differences

The RTX 3080 Ti is built on NVIDIA's Ampere architecture using the GA102 chip fabricated on Samsung's 8 nm process. It contains 28,300 million transistors on a 628 mm² die, yielding a transistor density of 45.1M per mm². The Radeon Pro 5300 uses AMD's RDNA 1.0 architecture with the Navi 14 chip on TSMC's 7 nm process, packing 6,400 million transistors into a 158 mm² die with a density of 40.5M per mm².

The RTX 3080 Ti features 80 RT cores and 320 tensor cores, neither of which the Radeon Pro 5300 possesses. NVIDIA's card supports DirectX 12 Ultimate (12_2), while the AMD card only reaches DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4.

The Radeon Pro 5300 belongs to the Radeon Pro Mac (Navi Series) generation with no predecessor or successor listed. The RTX 3080 Ti is part of the GeForce 30 generation, succeeding GeForce 20 and preceding GeForce 40. The NVIDIA card was released on 2021-05-30, while the AMD card launched earlier on 2020-08-03. Both are end-of-life products.

Head-to-Head Benchmarks

The head-to-head comparison includes only two shared benchmarks, and NVIDIA wins both by overwhelming margins. In Geekbench OpenCL, the RTX 3080 Ti scores 191,309 against the Radeon Pro 5300's 38,720, a 394.1% difference. This means the RTX 3080 Ti delivers nearly 5x the OpenCL performance of the AMD card.

Geekbench Vulkan tells a similar story: the RTX 3080 Ti scores 171,798 while the Radeon Pro 5300 manages 35,915, a 378.3% gap. The NVIDIA card is roughly 4.8x faster in this API.

These results align with the raw hardware differences. The RTX 3080 Ti's FP32 throughput of 34.10 TFLOPS is 8.1x higher than the Radeon Pro 5300's 4.224 TFLOPS. The bandwidth advantage of 912.4 GB/s versus 224.0 GB/s further compounds the compute lead.

Interestingly, the Radeon Pro 5300 has a Geekbench Metal score of 50,195, but this test is not part of the head-to-head because the RTX 3080 Ti does not have a corresponding Metal result. The AMD card's average score of 41,610, which places it 0.9% above the RTX 3080 Ti's 41,224, is therefore driven by its Metal performance and the absence of comparable NVIDIA data in that benchmark.

The RTX 3080 Ti also has a wider benchmark portfolio: it is tested across Passmark DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute, plus 3DMark Steel Nomad DX12. Its Passmark G3D score is 26,896, and its 3DMark Steel Nomad score is 5,077. The Radeon Pro 5300 lacks these results entirely, making direct comparisons in DirectX workloads impossible from the available data.

The Verdict

The data is unambiguous: the RTX 3080 Ti is the superior compute performer, winning both head-to-head benchmarks by margins of 394.1% and 378.3%. In any workload that uses OpenCL or Vulkan, the NVIDIA card is approximately 4-5x faster than the Radeon Pro 5300.

However, the average benchmark scores tell a nuanced story. The Radeon Pro 5300's average of 41,610 slightly edges the RTX 3080 Ti's 41,224, but this is due to the AMD card's strong Metal score of 50,195, which has no NVIDIA counterpart in the data. If the RTX 3080 Ti had a Metal result, its average would likely be substantially higher.

The RTX 3080 Ti is the choice for any user prioritizing raw compute, ray tracing, or high-bandwidth memory workloads. Its 80 RT cores, 320 tensor cores, and 912.4 GB/s bandwidth make it a versatile performer across modern APIs. The Radeon Pro 5300, with its 85 W TDP and no power connectors, is designed for integrated or low-power systems where the RTX 3080 Ti's 350 W requirement and dual-slot footprint are impractical.

The Radeon Pro 5300's 7 nm process and smaller die (158 mm² versus 628 mm²) suggest efficiency advantages, but the benchmark data does not include power efficiency or thermal metrics. From a pure performance standpoint, the RTX 3080 Ti wins decisively.

Where Each One Wins

The RTX 3080 Ti wins in every head-to-head benchmark included in the data. Its 394.1% lead in Geekbench OpenCL and 378.3% lead in Geekbench Vulkan make it the clear choice for compute-intensive applications such as rendering, scientific simulation, or machine learning workloads that leverage these APIs.

The NVIDIA card also wins in feature support. It offers DirectX 12 Ultimate, dedicated ray tracing cores, and tensor cores, none of which the Radeon Pro 5300 provides. For gaming or professional workloads using ray tracing or AI acceleration, the RTX 3080 Ti is the only option between the two.

The Radeon Pro 5300's wins are contextual rather than performance-based. It has a Geekbench Metal score of 50,195, which is not compared against the RTX 3080 Ti because the NVIDIA card lacks a Metal result. In Apple ecosystem environments where Metal is the primary API, the Radeon Pro 5300 is the relevant choice by default.

The AMD card's 85 W TDP, lack of power connectors, and IGP form factor make it suitable for compact or low-power Mac systems. The RTX 3080 Ti's 350 W TDP, 12-pin connector, and 285 mm length require a full desktop chassis with substantial power delivery.

For users with a specific need for OpenCL or Vulkan performance, the RTX 3080 Ti is unquestionably the winner. For users constrained by power, space, or platform requirements—particularly Mac-based systems—the Radeon Pro 5300 remains a functional option despite its lower compute scores. The data shows the RTX 3080 Ti is the performance king, but the Radeon Pro 5300 occupies a niche that the NVIDIA card cannot fill due to its physical and power requirements.
