AMD Radeon Pro 575 vs NVIDIA GeForce RTX 4070 Comparison

The AMD Radeon Pro 575 and NVIDIA GeForce RTX 4070 represent two vastly different eras of GPU design, separated by nearly six years of architectural evolution. The data shows a clear generational gulf, yet the older AMD part still holds a specific niche. This analysis compares their benchmark scores, architectural foundations, and feature sets to determine where each card remains viable.

Where Each One Wins

The benchmark data is unequivocal: the NVIDIA GeForce RTX 4070 wins every head-to-head comparison, claiming 2 out of 2 victories. The AMD Radeon Pro 575 records zero wins. This is not a close contest in raw compute. The RTX 4070’s advantage is most pronounced in compute-heavy workloads, where its modern architecture and massive shader count deliver results that dwarf the older AMD part.

However, the AMD Radeon Pro 575’s win condition is not found in the head-to-head benchmarks but in its deployment context. As an MXM Module with no power connectors and a 150 W TDP, it is designed for portable workstations where the RTX 4070’s dual-slot, 200 W, 16-pin design cannot fit. The AMD card’s 82nd percentile ranking among all GPUs, despite being from 2017, indicates it remains a competent performer for its era. The RTX 4070, with an 81st percentile, is technically ranked slightly lower overall, though this metric aggregates across all GPUs and does not reflect their relative standings in modern workloads.

The practical split is clear: the RTX 4070 wins on absolute performance, while the Radeon Pro 575 wins on form-factor adaptability. For legacy Mac Pro systems or specialized embedded applications requiring the MXM standard, the AMD card is the only option. For any desktop build where space and power are available, the NVIDIA card is the superior choice.

Architecture Differences

The architectural chasm between these two GPUs is monumental. The AMD Radeon Pro 575 uses the Ellesmere chip based on GCN 4.0 architecture, built on a 14 nm process at GlobalFoundries. It packs 5,700 million transistors into a 232 mm² die, yielding a transistor density of 24.6M per mm². In contrast, the NVIDIA GeForce RTX 4070 uses the AD104 chip based on Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It crams 35,800 million transistors into a larger 294 mm² die, achieving a density of 121.8M per mm²—nearly five times denser.

The compute resources tell the story of generational progress. The Radeon Pro 575 has 2,048 shading units, 128 TMUs, and 32 ROPs. The RTX 4070 has 5,888 shading units, 184 TMUs, and 64 ROPs—roughly 2.9x, 1.4x, and 2x the AMD’s counts, respectively. Critically, the RTX 4070 adds 46 RT cores and 184 tensor cores, features entirely absent from the AMD card. This means the NVIDIA GPU supports hardware-accelerated ray tracing and AI-driven DLSS, capabilities the Radeon Pro 575 cannot offer.

Memory architecture also diverges sharply. The AMD card uses 4 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s bandwidth. The RTX 4070 uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s. Despite the narrower bus, the RTX 4070’s faster memory and newer technology provide over 2.3x the bandwidth. The process node difference (14 nm vs 5 nm) explains the massive transistor density gap, while the foundry split (GlobalFoundries vs TSMC) highlights different manufacturing ecosystems. The RTX 4070 supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and PCIe 4.0, while the AMD card is limited to DirectX 12 (12_0), Vulkan 1.3, and PCIe 3.0.

Head-to-Head Benchmarks

The two shared benchmark tests reveal the scale of NVIDIA’s dominance. In Geekbench OpenCL, the AMD Radeon Pro 575 scores 34,596, while the NVIDIA GeForce RTX 4070 scores 154,858. This is a delta of -77.7%, meaning the RTX 4070 is roughly 4.5 times faster in OpenCL compute. This massive gap reflects the RTX 4070’s 29.15 TFLOPS FP32 performance versus the AMD’s 4.489 TFLOPS—a 6.5x difference in theoretical peak, though real-world scaling is less than perfect.

In Geekbench Vulkan, the scores are 37,878 for AMD and 174,152 for NVIDIA, a delta of -78.3%. The Vulkan gap is even slightly larger than OpenCL, indicating the NVIDIA architecture scales better with modern low-level APIs. The RTX 4070’s Vulkan score is 4.6 times higher. These results align with the architectural differences: the RTX 4070’s 5 nm process allows higher clock speeds (1920 MHz base, 2475 MHz boost) versus the AMD’s unspecified base/boost clocks, and its 5888 shading units process far more data per cycle.

Notably, the AMD’s Geekbench Vulkan score (37,878) is actually higher than its OpenCL score (34,596), suggesting GCN 4.0 handles Vulkan relatively well for its era. The RTX 4070 shows the opposite trend, with Vulkan (174,152) exceeding OpenCL (154,858), indicating Ada Lovelace is optimized for modern API workloads. The head-to-head data shows zero wins for AMD, but the delta percentages (-77.7% and -78.3%) are consistent, implying the performance gap is relatively uniform across both compute APIs.

The Verdict

The data indicates a clear choice for most users: the NVIDIA GeForce RTX 4070. Its benchmark scores are overwhelmingly superior—4.5x higher in OpenCL and 4.6x higher in Vulkan. The architectural advantages are equally stark: 5 nm versus 14 nm process, 35.8 billion versus 5.7 billion transistors, and the inclusion of dedicated RT and tensor cores. The RTX 4070’s 12 GB GDDR6X memory with 504.2 GB/s bandwidth provides over twice the memory bandwidth of the AMD’s 4 GB GDDR5. For any workload requiring modern graphics features, ray tracing, or AI acceleration, the RTX 4070 is the only viable option.

However, the AMD Radeon Pro 575’s MXM Module form factor is its unique selling point. No other data in this comparison offers an alternative for systems requiring this specific slot type. Its 150 W TDP with no external power connectors makes it suitable for environments where the RTX 4070’s 200 W requirement and 16-pin connector are impractical. The AMD card’s 82nd percentile ranking versus the RTX 4070’s 81st suggests that in the broader GPU landscape, neither is an outlier—the RTX 4070’s lower percentile is likely due to its high performance being averaged against specialized compute cards.

The verdict is context-dependent. If your system accepts an MXM module and you need a drop-in replacement for a legacy Mac Pro or embedded workstation, the Radeon Pro 575 is the only choice. If you are building or upgrading a desktop with standard PCIe slots, the RTX 4070 offers unmatched performance, with its only drawback being the larger physical footprint and power requirements. The data does not support any scenario where the AMD card outperforms the NVIDIA card in raw compute, but it does support scenarios where the AMD card is the only physically compatible option.
