AMD Radeon Pro 575 vs NVIDIA GeForce RTX 4080 Mobile Comparison

AMD Radeon Pro 575 and NVIDIA GeForce RTX 4080 Mobile occupy opposite ends of the mobile graphics spectrum, separated by nearly six years of architectural evolution. The data shows the RTX 4080 Mobile wins both shared benchmark tests decisively, yet the Radeon Pro 575 holds a higher overall percentile rank, creating an interesting divergence between raw compute results and aggregate standing.

The Verdict

The NVIDIA GeForce RTX 4080 Mobile is the clear performance winner in direct comparison, taking 2 out of 2 shared benchmarks. Its Geekbench OpenCL score of 159,575 represents a 78.3% advantage over the AMD Radeon Pro 575’s 34,596, while its Geekbench Vulkan result of 145,807 beats the AMD part’s 37,878 by 74%. For any workload leveraging OpenCL or Vulkan, the RTX 4080 Mobile is categorically faster.

However, the verdict is not one-sided when considering aggregate metrics. The Radeon Pro 575 posts an average benchmark score of 39,555, which sits at the 82nd percentile of all GPUs, while the RTX 4080 Mobile’s average score of 38,135 places it at the 81st percentile. The AMD card’s nearest rivals include the NVIDIA RTX A500 Mobile (39,568, 0% delta) and the AMD Radeon Pro WX 7100 (40,063, -1.3% delta), showing it clusters tightly with professional mobile offerings. The RTX 4080 Mobile’s nearest rivals are more consumer-oriented, including the GeForce MX570 (38,299, -0.4% delta) and the GeForce RTX 4070 (37,648, 1.3% delta).

The RTX 4080 Mobile suits users prioritizing raw compute throughput in modern APIs, especially Vulkan-based applications. The Radeon Pro 575, despite being end-of-life since its 2017 release, remains relevant for legacy OpenCL workloads and holds its own in aggregate rankings. Data indicates the RTX 4080 Mobile is the choice for current-generation gaming and compute, while the Radeon Pro 575 serves established professional pipelines that do not require the newer card’s feature set.

Architecture Differences

The architectural gap between these two GPUs is substantial. The AMD Radeon Pro 575 uses the Ellesmere chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It contains 5,700 million transistors on a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The NVIDIA GeForce RTX 4080 Mobile uses the AD104 chip with Ada Lovelace architecture, produced on TSMC’s 5 nm process. It packs 35,800 million transistors into a 294 mm² die, achieving 121.8 million transistors per square millimeter — roughly five times the density of the older AMD part.

Memory configurations differ fundamentally. The Radeon Pro 575 provides 4 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s bandwidth. The RTX 4080 Mobile offers 12 GB of GDDR6 on a 192-bit bus, with memory clocked at 2250 MHz (18 Gbps effective) for 432.0 GB/s bandwidth — exactly double the AMD card’s throughput. The NVIDIA part also features dedicated ray tracing cores (58) and tensor cores (232), neither of which exist on the GCN 4.0 architecture.

API support reflects the generational leap. The Radeon Pro 575 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The RTX 4080 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface also advances from PCIe 3.0 x16 on the AMD card to PCIe 4.0 x16 on the NVIDIA card. The Radeon Pro 575 uses an MXM module form factor, while the RTX 4080 Mobile is integrated as an IGP. Both are marked as end-of-life versus active production status respectively, with the AMD card releasing in June 2017 and the NVIDIA card in January 2023.

Specification Differences

The two GPUs differ across nearly every specification field. The process node shifts from 14 nm (AMD) to 5 nm (NVIDIA), with the foundry changing from GlobalFoundries to TSMC. Transistor count rises from 5,700 million to 35,800 million, while die size increases from 232 mm² to 294 mm². Transistor density jumps from 24.6M/mm² to 121.8M/mm².

DirectX support moves from 12 (12_0) to 12 Ultimate (12_2), Vulkan from 1.3 to 1.4, while OpenGL remains 4.6 on both.

Head-to-Head Benchmarks

The head-to-head comparison consists of two benchmark tests, and the NVIDIA GeForce RTX 4080 Mobile wins both. In Geekbench OpenCL, the RTX 4080 Mobile scores 159,575 against the Radeon Pro 575’s 34,596, a delta of -78.3% from the AMD card’s perspective. This is the larger margin of the two tests, showing NVIDIA’s advantage is most pronounced in OpenCL compute workloads.

The Geekbench Vulkan test shows a similar but slightly smaller gap. The RTX 4080 Mobile achieves 145,807, while the Radeon Pro 575 manages 37,878, resulting in a -74% delta. Both tests confirm the NVIDIA card operates at roughly four times the performance level of the AMD card in these specific APIs.

For context, the Radeon Pro 575’s nearest rival is the NVIDIA RTX A500 Mobile at 39,568 average score (0% delta), and the AMD Radeon Pro 575X at 39,116 (1.1% delta). The RTX 4080 Mobile’s nearest rival is the NVIDIA GeForce MX570 at 38,299 (-0.4% delta), with the RTX 5080 Mobile close behind at 38,349 (-0.6% delta). These rival comparisons suggest that while the RTX 4080 Mobile dominates the Radeon Pro 575 in raw tests, its overall standing is not dramatically higher than several other mobile GPUs in the database.

Where Each One Wins

The NVIDIA GeForce RTX 4080 Mobile wins in every direct benchmark comparison, making it the obvious choice for OpenCL and Vulkan-heavy applications. Its 24.72 TFLOPS FP32 performance, 432.0 GB/s memory bandwidth, and 12 GB VRAM capacity position it for modern workloads such as real-time rendering, machine learning inference via tensor cores, and ray-traced graphics. The 58 RT cores enable hardware-accelerated ray tracing, a feature entirely absent from the AMD card. Its lower 110 W TDP also means it delivers this performance at reduced power consumption compared to the Radeon Pro 575’s 150 W.

The AMD Radeon Pro 575 retains advantages in specific legacy contexts. Its higher average benchmark score (39,555 vs 38,135) and percentile ranking (82nd vs 81st) indicate that across a broader range of tests not in the head-to-head set, it performs competitively. The 256-bit memory bus, while slower overall, may benefit certain bandwidth-sensitive legacy workloads. Its MXM form factor offers upgrade potential in compatible systems, and its GCN 4.0 architecture has mature driver support for older professional applications that predate the Ada Lovelace generation.

For users running Vulkan-based games or compute, the RTX 4080 Mobile is the only rational choice based on the 74-78% performance margins. For those maintaining legacy OpenCL pipelines on existing MXM-based systems, the Radeon Pro 575’s higher aggregate ranking and established ecosystem make it a defensible option. The data does not support choosing the AMD card for any modern, performance-critical workload, but its endurance in aggregate benchmarks shows it remains a capable professional part within its niche.
