AMD Radeon Pro 575 vs NVIDIA GeForce RTX 5080 Mobile Comparison

The AMD Radeon Pro 575 and the NVIDIA GeForce RTX 5080 Mobile represent two vastly different eras of mobile graphics. The data shows a decisive generational gap, with the NVIDIA part dominating every shared benchmark metric by a massive margin. However, the AMD card remains a relevant point of comparison for legacy systems, particularly in the Mac ecosystem where it originally shipped. This analysis breaks down the architectural chasm and performance deltas between the 2017-era workstation GPU and the 2025 flagship mobile part.

Where Each One Wins

Based on the benchmark data provided, there is no contest in terms of raw compute wins. The NVIDIA GeForce RTX 5080 Mobile wins both head-to-head benchmarks available, leaving the AMD Radeon Pro 575 with zero victories. The RTX 5080 Mobile’s wins are not marginal; they are overwhelming, with deltas exceeding 77% in the tested workloads.

The AMD Radeon Pro 575 does not win any benchmark in this comparison. Its relevance is confined to its historical context as an end-of-life product from the Radeon Pro Mac (500 Series) generation. It holds an 82nd percentile ranking among all GPUs, which is surprisingly high for its age, but this confirms the modest performance of the broader GPU landscape at the time of its release, rather than a competitive threat to the RTX 5080 Mobile.

The NVIDIA GeForce RTX 5080 Mobile, conversely, wins all shared tests. Its victory in Geekbench OpenCL and Vulkan is absolute, with scores of 166986 and 169754 respectively, compared to the AMD’s 34596 and 37878. The RTX 5080 Mobile’s percentile ranking sits at 81, which is nearly identical to the AMD part, but this is misleading. The RTX 5080 Mobile is an active, current-generation product, while the Radeon Pro 575 is end-of-life. The RTX 5080 Mobile’s win condition is not just about beating this specific old AMD card, but about establishing itself as a top-tier mobile compute solution, as evidenced by its other scores like the 27711 in Passmark G3D.

Architecture Differences

The architectural divide between these two GPUs is as wide as their release dates suggest. The AMD Radeon Pro 575 is built on the GCN 4.0 architecture, utilizing the Ellesmere chip fabricated on a 14 nm process at GlobalFoundries. It packs 5,700 million transistors on a 232 mm² die, resulting in a transistor density of 24.6M per mm². In contrast, the NVIDIA GeForce RTX 5080 Mobile uses the Blackwell 2.0 architecture with the GB203 chip, manufactured on a 5 nm process at TSMC. This newer node allows for a staggering 45,600 million transistors on a 378 mm² die, achieving a density of 120.6M per mm². This is a fundamental shift in manufacturing capability, enabling the NVIDIA chip to house nearly eight times the transistors.

The compute configurations differ drastically. The AMD Radeon Pro 575 features 2048 shading units, 128 TMUs, and 32 ROPs. It has no dedicated RT or Tensor cores, relying purely on traditional shader hardware. The NVIDIA GeForce RTX 5080 Mobile, however, is a completely different beast. It boasts 7680 shading units, 240 TMUs, and 96 ROPs, and adds 60 RT cores and 240 Tensor cores for hardware-accelerated ray tracing and AI workloads. This translates to a massive difference in raw throughput: the AMD card delivers 4.489 TFLOPS of FP32 and FP16 performance, while the NVIDIA card delivers 23.04 TFLOPS in both, representing a fivefold increase in raw compute power.

Memory architecture also tells a story of two generations. The AMD Radeon Pro 575 comes with 4 GB of GDDR5 memory on a 256-bit bus, providing 217.0 GB/s of bandwidth. The RTX 5080 Mobile ships with 16 GB of GDDR7 memory, also on a 256-bit bus, but achieves a colossal 896.0 GB/s of bandwidth. The memory clock speeds highlight this too: AMD’s memory runs at 1695 MHz (6.8 Gbps effective), while NVIDIA’s runs at 1750 MHz (28 Gbps effective). The feature set differences are equally stark. The AMD card supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, while the NVIDIA card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, along with the aforementioned RT and Tensor core capabilities. The bus interface also jumps from PCIe 3.0 x16 on the AMD to PCIe 5.0 x16 on the NVIDIA, doubling the potential data transfer rate to the CPU.

Head-to-Head Benchmarks

The head-to-head results are a one-sided affair, confirming the generational gap. In Geekbench OpenCL, the NVIDIA GeForce RTX 5080 Mobile scores 166986, while the AMD Radeon Pro 575 scores 34596. This results in a delta of -79.3% for the AMD card, meaning the NVIDIA part is nearly five times faster in this compute test. This is a direct reflection of the architectural advantages: more shading units, higher clocks, and faster memory all contribute to this crushing defeat.

The Geekbench Vulkan test tells a similar story. The RTX 5080 Mobile posts a score of 169754, compared to the Radeon Pro 575’s 37878. The delta here is -77.7%, again favoring the NVIDIA GPU. While Vulkan is a cross-platform API that can sometimes favor different architectures, the sheer compute disparity here overwhelms any potential API-level optimizations. The RTX 5080 Mobile’s performance is not just a linear scaling of cores; it benefits from a more efficient architecture and significantly higher memory bandwidth, allowing it to feed its 7680 shading units effectively. The AMD card, with its GCN 4.0 architecture and 4.489 TFLOPS, simply cannot compete.

It is notably the AMD Radeon Pro 575 has a Geekbench Metal score of 46192, a benchmark that the NVIDIA card does not share in this dataset. This is the AMD card’s only potential saving grace, as Metal is the primary graphics API on macOS, and the Radeon Pro 575 was designed for Mac Pro systems. However, without a comparable NVIDIA score in this test, it remains a point of reference only for Apple-centric workloads, not a competitive metric against the RTX 5080 Mobile.

The Verdict

From the data, the choice is unambiguous for any modern workload. The NVIDIA GeForce RTX 5080 Mobile is the superior product by every shared metric, delivering roughly 4.8 times the OpenCL performance and 4.5 times the Vulkan performance of the AMD Radeon Pro 575. Its architectural advantages—Blackwell 2.0 on a 5 nm node, 60 RT cores, 240 Tensor cores, and 896 GB/s of GDDR7 bandwidth—make it a formidable mobile computing platform. Its 16 GB of VRAM is also four times the capacity of the AMD part, which is critical for modern content creation and AI inference.

The AMD Radeon Pro 575 should only be considered in its native context: a legacy component for older Mac Pro systems. Its 150 W TDP is higher than the RTX 5080 Mobile’s 80 W TDP, yet it offers a fraction of the performance. Its end-of-life status and 4 GB VRAM limit make it unsuitable for any contemporary demanding tasks. If you are building a new system or upgrading a modern laptop, the NVIDIA GeForce RTX 5080 Mobile is the only rational choice based on this data. Its active production status and successor to the GeForce 40 Mobile line confirm its place as a current-gen solution. The Radeon Pro 575, with a release date in 2017, is simply outclassed in every way that the benchmark results can measure.
