AMD Radeon Pro 575X vs NVIDIA GeForce RTX 3080 Ti Comparison

The NVIDIA GeForce RTX 3080 Ti and the AMD Radeon Pro 575X represent two vastly different eras and purposes in the GPU landscape. The data reveals a stark generational and performance chasm, with the RTX 3080 Ti delivering overwhelming compute superiority, while the Radeon Pro 575X holds a unique position as a legacy mobile solution. This analysis compares their benchmark scores, architectural foundations, and use-case scenarios strictly based on the provided data.

Head-to-Head Benchmarks

The direct comparison between these two cards, based on the shared benchmark tests, is not a contest; it is a demonstration of massive performance scaling. In the Geekbench OpenCL test, the NVIDIA GeForce RTX 3080 Ti scores 170,037, while the AMD Radeon Pro 575X manages 34,773. This results in a delta of 389%, meaning the RTX 3080 Ti is nearly four times faster in this compute-heavy workload.

The gap widens even further in the Geekbench Vulkan test. Here, the RTX 3080 Ti achieves a score of 192,697, compared to the Radeon Pro 575X's 37,919. This represents a 408.2% advantage for the NVIDIA card, indicating that the architecture handles modern graphics APIs with significantly more efficiency and raw power. The data shows a 2-0 win record for the RTX 3080 Ti in these head-to-head matchups.

This performance disparity is also reflected in their average benchmark scores. The RTX 3080 Ti posts an average score of 41,187, while the Radeon Pro 575X averages 39,116. While the average scores seem closer, this is an artifact of the different benchmark suites each card was tested with; the RTX 3080 Ti's suite includes more demanding tests like 3DMark Steel Nomad, where it scores 5,077, and PassMark G3D, where it scores 26,896. The Radeon Pro 575X's limited benchmark set does not challenge it in the same way, masking the true performance gulf seen in the direct comparisons.

Architecture Differences

The architectural divide between these two GPUs is foundational and explains the performance results. The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture using the GA102 chip, fabricated on an 8 nm process at Samsung. It packs 28,300 million transistors onto a 628 mm² die, resulting in a transistor density of 45.1M per mm². This massive chip is configured with 10,240 shading units, 320 TMUs, and 112 ROPs, alongside 80 RT cores and 320 Tensor cores dedicated to ray tracing and AI workloads.

In contrast, the AMD Radeon Pro 575X uses the older GCN 4.0 architecture with the Ellesmere chip, built by GlobalFoundries on a more mature 14 nm process. It contains only 5,700 million transistors on a 232 mm² die, with a density of 24.6M per mm². Its compute configuration is far simpler, featuring 2,048 shading units, 128 TMUs, and 32 ROPs. Crucially, the Radeon Pro 575X has no dedicated RT cores or Tensor cores, meaning it lacks the hardware acceleration for ray tracing and AI features that the RTX 3080 Ti provides.

Memory architecture further separates them. The RTX 3080 Ti uses 12 GB of GDDR6X memory on a 384-bit bus, delivering a bandwidth of 912.4 GB/s. The Radeon Pro 575X is limited to 4 GB of GDDR5 on a 256-bit bus, resulting in a much lower bandwidth of 217.0 GB/s. The RTX 3080 Ti also supports PCIe 4.0 x16, while the Radeon Pro 575X is limited to PCIe 3.0 x16. These differences in compute cores, memory capacity, and bus technology are the primary drivers of the performance gap.

Where Each One Wins

The benchmark data suggests a clear division of use cases. The NVIDIA GeForce RTX 3080 Ti is the victor in every benchmark where both were tested, including OpenCL and Vulkan compute workloads. Its 34.10 TFLOPS of FP32 performance, compared to the Radeon Pro 575X's 4.489 TFLOPS, indicates it is suited for demanding tasks like 3D rendering, complex simulations, and high-end gaming where raw throughput is paramount. The presence of RT and Tensor cores also makes it the choice for applications leveraging ray tracing and AI-based features like DLSS.

The AMD Radeon Pro 575X, however, has a different domain. Its profile as an "IGP" (Integrated Graphics Processor) with "Portable Device Dependent" display outputs and no power connectors suggests it is designed for a specific, power-constrained environment like a Mac laptop. Its strength is not in absolute performance but in its form factor and thermal envelope, with a 150 W TDP. It is a capable solution for professional workloads that do not require the extreme performance of a desktop-class GPU, such as basic photo editing, video playback, and general productivity. The data shows that in the field of portability and integration, it wins by default, as the RTX 3080 Ti is a dual-slot desktop card.

The Verdict

The data makes a compelling case for the NVIDIA GeForce RTX 3080 Ti as the superior performer in every measurable compute metric. For any user requiring maximum throughput in OpenCL or Vulkan workloads, the choice is unequivocal. The RTX 3080 Ti's architecture, with its dedicated RT and Tensor cores, also positions it for future-proofing in applications that leverage these features. Its 12 GB of GDDR6X memory and 912.4 GB/s bandwidth provide a significant advantage for large datasets and high-resolution textures.

The AMD Radeon Pro 575X, however, is not without merit, though its value is contextual. Its designation as an IGP with no power connectors and portable device-dependent outputs indicates it is built for a specific, integrated mobile platform. For a user in that ecosystem, the data shows it offers a baseline level of performance that is adequate for standard professional tasks. However, from a pure performance standpoint, the comparison is one-sided. The RTX 3080 Ti is the clear winner for anyone who can accommodate its physical size and power requirements.
