Architecture Differences

The two GPUs come from fundamentally different design generations and manufacturing nodes. The NVIDIA GeForce RTX 4080 uses the AD103 chip built on Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The AMD Radeon Pro 575 uses the Ellesmere chip built on GCN 4.0 architecture, fabricated by GlobalFoundries on a 14 nm process. This node difference alone explains a significant portion of the performance gap, as the RTX 4080 packs 45,900 million transistors into a 379 mm² die, yielding a density of 121.1M per mm². The Radeon Pro 575 has 5,700 million transistors on a 232 mm² die, with a density of 24.6M per mm².

The compute architectures differ sharply. The RTX 4080 has 9,728 shading units, 304 texture mapping units, and 112 render output units. It also includes 76 dedicated ray tracing cores and 304 tensor cores, enabling hardware-accelerated ray tracing and AI workloads. The Radeon Pro 575 has 2,048 shading units, 128 texture mapping units, and 32 render output units, with no dedicated ray-tracing or tensor cores listed. The pixel rate is 280.6 GPixel/s for NVIDIA versus 35.07 GPixel/s for AMD, and the texture rate is 761.5 GTexel/s versus 140.3 GTexel/s.

Feature support also diverges. The RTX 4080 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro 575 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The NVIDIA card is a triple-slot design with a single 16-pin power connector and a suggested PSU of 700 W. The AMD card is an MXM module with no power connectors and no suggested PSU listed. The RTX 4080 has a 310 mm length, 140 mm height, and 61 mm width. The Radeon Pro 575 has no listed physical dimensions, reflecting its portable device orientation.

Head-to-Head Benchmarks

The recorded head-to-head data covers two compute-oriented tests, and the NVIDIA GeForce RTX 4080 dominates both with overwhelming margins. In Geekbench OpenCL, the RTX 4080 scores 214,739 against 34,596 for the Radeon Pro 575. That is a 520.7% advantage, meaning the NVIDIA card delivers roughly six times the compute throughput in this workload. This test stresses general-purpose compute, where the combination of 9,728 shading units, higher clock rates, and newer memory architecture gives the RTX 4080 a decisive edge.

In Geekbench Vulkan, the gap widens further. The RTX 4080 scores 263,779, while the Radeon Pro 575 scores 37,878, a delta of 596.4%. This is the larger of the two wins by percentage, showing that the NVIDIA card excels in graphics API performance under Vulkan as well. The RTX 4080's 16 GB of GDDR6X memory with 716.8 GB/s bandwidth and 304 texture mapping units contribute heavily to this result, while the Radeon Pro 575's 4 GB GDDR5 memory and 217.0 GB/s bandwidth create a hard ceiling.

The overall wins tally is 2 for the RTX 4080 and 0 for the Radeon Pro 575. There is no recorded benchmark where the AMD part pulls ahead. The RTX 4080 also records a higher average benchmark score of 54,247 versus 39,555, and its percentile ranking among all GPUs is 86 versus 82. Notably, the RTX 4080's nearest rivals in the database include the RTX 4080 SUPER (0.1% faster), the AMD Radeon Pro W5700X (1.1% slower), and the AMD Radeon RX 6750 GRE 12 GB (2.6% slower).

The Verdict

The raw data makes the hierarchy clear: the NVIDIA GeForce RTX 4080 is in a different performance class entirely. Its average benchmark score is 20,692 points higher than the AMD Radeon Pro 575, and it wins every recorded head-to-head test by a wide margin. The 520.7% OpenCL advantage and the 596.4% Vulkan advantage are not incremental improvements; they represent a generational leap in compute and graphics capacity.

The RTX 4080 is the obvious choice for any workload that demands high compute throughput, ray tracing, or tensor processing. It has 9,728 shading units, 76 ray-tracing cores, and 304 tensor cores, none of which the Radeon Pro 575 can match. The 16 GB memory capacity and 716.8 GB/s bandwidth also provide far more headroom for large datasets and high-resolution textures.

The Radeon Pro 575 is a much older, lower-power part. It consumes 150 W versus 320 W, uses a 14 nm node, and has only 2,048 shading units. Its 4 GB of GDDR5 memory at 217.0 GB/s is fixed, but it is a portable MXM module with no power connectors. It cannot compete on raw performance, but its physical form factor and lower power draw make it suited for specific embedded or mobile scenarios.

For users who only need basic graphics acceleration in a portable device, the Radeon Pro 575 is a functional option. For any serious workload, the RTX 4080 is the only answer from the data.

Where Each One Wins

The NVIDIA GeForce RTX 4080 wins in every tested category. In Geekbench OpenCL, the RTX 4080 produces 214,739 points versus 34,596 for the Radeon Pro 575, making it the clear choice for compute-heavy tasks such as rendering, simulation, or machine learning inference. The 520.7% delta shows that any OpenCL-based application will run over five times faster on NVIDIA hardware.

In Geekbench Vulkan, the RTX 4080 scores 263,779 versus 37,878, a 596.4% margin. This is the biggest win in the dataset, so the RTX 4080 is also the better choice for Vulkan-based game engines or graphics applications that use the Vulkan API.

The Radeon Pro 575 has no recorded wins in the head-to-head tests. However, it does have strengths in physical characteristics. Its 150 W power draw is less than half the RTX 4080's 320 W, and it is an MXM module, which means it fits into certain portable or compact systems that cannot accommodate a triple-slot, 310 mm long card. The Radeon Pro 575 also requires no power connectors and no suggested PSU, while the RTX 4080 needs a 16-pin connector and a 700 W power supply.

For use cases, the split is clear. The RTX 4080 wins for desktop workstations, high-end gaming, VR, or any GPU-compute task where performance is the priority. The Radeon Pro 575 wins only in the narrow case of a low-power, small-form-factor, portable device where the RTX 4080 cannot physically fit. In every benchmark that the database covers, the RTX 4080 dominates the Radeon Pro 575.
