Q: How do the percentile rankings compare?

A: The AMD Radeon Pro 575X sits in the 82nd percentile of all GPUs, while the NVIDIA TITAN RTX sits in the 76th percentile. Despite the TITAN RTX winning all head-to-head tests, its average benchmark score of 31676 is lower than the AMD card's 39116 due to different test suites.

Architecture Differences

The AMD Radeon Pro 575X uses the Ellesmere chip based on GCN 4.0 architecture, manufactured on a 14 nm process at GlobalFoundries. The NVIDIA TITAN RTX uses the TU102 chip based on Turing architecture, manufactured on a 12 nm process at TSMC. This process difference contributes to the TITAN RTX's larger die: 754 mm² versus 232 mm² for the AMD part.

The transistor counts tell a story of scale. AMD packs 5,700 million transistors, while NVIDIA packs 18,600 million. The transistor densities are essentially matched at 24.6M per mm² for AMD and 24.7M per mm² for NVIDIA, meaning the NVIDIA chip uses its larger area for more functional units rather than tighter packing.

Compute resources diverge sharply. The AMD card has 2048 shading units, 128 texture mapping units, and 32 ROPs. The NVIDIA card has 4608 shading units, 288 TMUs, and 96 ROPs. Additionally, the TITAN RTX includes 72 RT cores and 576 tensor cores, features completely absent from the AMD Radeon Pro 575X. These dedicated hardware units enable ray tracing and AI-accelerated workloads that the AMD card cannot accelerate in hardware.

The memory architectures differ fundamentally. AMD uses 4 GB of GDDR5 on a 256-bit bus, while NVIDIA uses 24 GB of GDDR6 on a 384-bit bus. The memory clock also differs: AMD runs at 1695 MHz (6.8 Gbps effective), NVIDIA at 1750 MHz (14 Gbps effective). The resulting bandwidth is 217.0 GB/s for AMD versus 672.0 GB/s for NVIDIA.

Power delivery reflects the performance gap. The AMD card consumes 150 W and requires no external power connectors, fitting as an integrated GPU (IGP) in portable devices. The NVIDIA card consumes 280 W, needs two 8-pin power connectors, and requires a 600 W suggested power supply. The NVIDIA card is a dual-slot design measuring 267 mm long, while the AMD card's dimensions are portable-device dependent.

Head-to-Head Benchmarks

The database records two direct comparisons between these cards. Both are comprehensive wins for the NVIDIA TITAN RTX.

In Geekbench OpenCL, the TITAN RTX scores 144858 against the Radeon Pro 575X's 34773. This is a 76% advantage for NVIDIA. The raw compute throughput of the TITAN RTX, with its 16.31 TFLOPS FP32 performance versus 4.489 TFLOPS for AMD, explains the magnitude of this gap. The TITAN RTX also doubles its FP32 throughput in FP16 mode at 32.62 TFLOPS (2:1 ratio), whereas the AMD card operates at 4.489 TFLOPS in both FP16 and FP32 (1:1 ratio).

In Geekbench Vulkan, the TITAN RTX scores 136073 against 37919 for the AMD card, a 72.1% lead. Vulkan performance tracks the same hierarchy as OpenCL, with NVIDIA's larger shading core count and higher memory bandwidth providing consistent advantages across API boundaries.

The texture and pixel throughput numbers reinforce these results. The NVIDIA card achieves 509.8 GTexel/s and 169.9 GPixel/s, while the AMD card manages 140.3 GTexel/s and 35.07 GPixel/s. These fill rate figures directly influence rasterization-heavy workloads.

It is importantly the AMD card's average benchmark score of 39116 across its test suite is higher than the TITAN RTX's average of 31676. This apparent contradiction stems from different benchmark selections. The AMD card's Geekbench scores (44655 Metal, 34773 OpenCL, 37919 Vulkan) skew its average upward, while the TITAN RTX's Passmark scores (including low DirectX 9 and DirectX 12 results) pull its average down. The head-to-head comparisons, which use identical workloads, are the more reliable indicator of relative performance.

The Verdict

The data is unambiguous: the NVIDIA TITAN RTX outperforms the AMD Radeon Pro 575X in every recorded head-to-head benchmark. The OpenCL score advantage of 76% and Vulkan score advantage of 72.1% place the TITAN RTX in a different performance tier entirely.

The AMD Radeon Pro 575X, however, holds a higher percentile ranking at 82 versus 76 for the TITAN RTX. This ranking reflects the AMD card's stronger results within its own benchmark suite, particularly its Geekbench Metal score of 44655. The AMD card also consumes far less power at 150 W versus 280 W, and requires no external power connectors.

For users constrained by physical space and power delivery, the AMD card is the only viable option between the two, as it is designed as an integrated GPU for portable devices. The NVIDIA card demands a dual-slot footprint, two 8-pin connectors, and a 600 W power supply.

For users who need maximum compute throughput, the TITAN RTX is the clear choice. Its 24 GB of GDDR6 memory, 576 tensor cores, and 72 RT cores enable workloads that are impossible on the AMD card. The FP16 performance at 32.62 TFLOPS versus 4.489 TFLOPS is particularly relevant for AI inference and training tasks.

The launch MSRP of 2,499 USD for the TITAN RTX reflects its flagship positioning, while the AMD card has no recorded MSRP due to its integration into portable systems.
