AMD Radeon Pro 575X vs NVIDIA GeForce GTX TITAN X Comparison

# AMD Radeon Pro 575X vs NVIDIA GeForce GTX TITAN X

The AMD Radeon Pro 575X and NVIDIA GeForce GTX TITAN X represent two very different approaches to graphics hardware, separated by four years of architectural evolution. The Radeon Pro 575X, built on a 14 nm process with GCN 4.0, targets professional Mac workflows with its integrated form factor, while the GTX TITAN X, fabricated on 28 nm with Maxwell 2.0, was NVIDIA's flagship consumer card of its generation. Benchmark data reveals a split decision: the AMD card dominates in Metal workloads with a 138.5% advantage, while the NVIDIA card takes decisive leads in OpenCL and Vulkan. This analysis breaks down where each GPU excels and which workloads favor which architecture.

Head-to-Head Benchmarks

The most striking result comes from Geekbench Metal, where the AMD Radeon Pro 575X scores 44,655 against the GTX TITAN X's 18,723. That is a 138.5% delta in AMD's favor, making it the single largest performance gap in any test. This is not a marginal win; it is a landslide that reflects how well GCN 4.0 scales in Apple's Metal API, likely due to driver optimization and the card's integration into Mac systems. For any Metal-based creative application, the Radeon Pro 575X is categorically superior.

However, the tables turn in OpenCL. The GTX TITAN X posts 41,471, beating the Radeon Pro 575X's 34,773 by 16.2%. This is a substantial margin, though not as extreme as the Metal result. The TITAN X's advantage here stems from its larger shading core count and higher raw compute throughput, which OpenCL workloads can exploit more effectively than Metal.

Vulkan tells a similar story. The GTX TITAN X scores 49,397 versus 37,919 for the Radeon Pro 575X, a 23.2% lead for NVIDIA. This is the TITAN X's best absolute score across all three tests, and it widens the gap compared to OpenCL. The pattern is clear: AMD wins one API decisively, NVIDIA wins two APIs with margins of 16-23%. In aggregate, the Radeon Pro 575X averages 39,116 across all benchmarks, while the GTX TITAN X averages 36,530, giving AMD a 2,586-point overall edge despite losing two of three tests.

Architecture Differences

The two GPUs could not be more different in construction. The AMD Radeon Pro 575X uses the Ellesmere chip on a 14 nm process from GlobalFoundries, packing 5,700 million transistors into a 232 mm² die. This yields a transistor density of 24.6 million per square millimeter, a figure that reflects the modern manufacturing node. In contrast, the GTX TITAN X uses the GM200 chip on TSMC's 28 nm process, with 8,000 million transistors spread across a massive 601 mm² die. Its density is just 13.3 million per square millimeter, showing how much larger and less dense the older process is.

Memory configurations diverge sharply. The Radeon Pro 575X comes with 4 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s of bandwidth. The GTX TITAN X offers 12 GB of GDDR5 on a 384-bit bus, reaching 336.6 GB/s. That is three times the capacity and roughly 55% more bandwidth, which matters for large datasets and high-resolution textures. Memory clocks are similar — 6.8 Gbps effective for AMD versus 7 Gbps effective for NVIDIA — but the wider bus gives NVIDIA the edge.

Compute resources favor NVIDIA heavily. The GTX TITAN X has 3,072 shading units, 192 texture mapping units, and 96 ROPs, compared to 2,048 shading units, 128 TMUs, and 32 ROPs on the Radeon Pro 575X. This translates to a pixel rate of 104.5 GPixel/s for NVIDIA versus 35.07 GPixel/s for AMD, and a texture rate of 209.1 GTexel/s versus 140.3 GTexel/s. In raw FP32 throughput, the TITAN X delivers 6.691 TFLOPS against AMD's 4.489 TFLOPS. Notably, the Radeon Pro 575X achieves a 1:1 FP16 to FP32 ratio, while the GTX TITAN X lists no FP16 capability.

Power and physical design also differ. The Radeon Pro 575X is an integrated GPU (IGP) with no power connectors and a 150 W TDP, designed for portable devices. The GTX TITAN X is a dual-slot card measuring 267 mm in length, 111 mm in height, and 38 mm in width, requiring 1x 6-pin and 1x 8-pin power connectors with a 250 W TDP and a 600 W suggested PSU. API support shows NVIDIA leading with DirectX 12_1 and Vulkan 1.4, while AMD offers DirectX 12_0 and Vulkan 1.3; both support OpenGL 4.6.

Where Each One Wins

The AMD Radeon Pro 575X is the clear winner for Metal-based applications. Its 44,655 Metal score is not just higher; it is more than double the GTX TITAN X's 18,723. This makes it the obvious choice for macOS users running Metal-accelerated creative software, video editing, or any workload that leverages Apple's graphics framework. The card's IGP form factor also means it fits into portable Mac devices, whereas the TITAN X requires a full desktop chassis with dual-slot cooling and external power.

The NVIDIA GeForce GTX TITAN X dominates in OpenCL and Vulkan. Its OpenCL score of 41,471 beats AMD by 16.2%, and its Vulkan score of 49,397 beats AMD by 23.2%. These are the APIs most common in cross-platform applications, game engines, and compute workloads. The TITAN X also offers 12 GB of VRAM versus 4 GB, making it far better suited for large model training, high-resolution rendering, or multi-monitor setups that exceed 4 GB of memory. Its 336.6 GB/s bandwidth and 96 ROPs give it a massive advantage in fill-rate-bound scenarios.

Looking at the nearest rivals provides context. The Radeon Pro 575X sits at the 82nd percentile among all GPUs, with its closest competitor being the AMD Radeon Pro 580X at 38,706 (just 1.1% behind) and the NVIDIA GeForce MX570 A at 38,691 (also 1.1% behind). The GTX TITAN X sits at the 80th percentile, with the AMD Radeon RX 5300M matching its average score almost exactly (36,529 versus 36,530, a 0% delta). This shows both cards are in a similar performance tier overall, but their strengths lie in different API ecosystems.

The Verdict

Choose the AMD Radeon Pro 575X if your primary environment is Metal-based. The data is unambiguous: a 138.5% advantage in Metal benchmarks means this card is in a different league for that API. It also has a lower TDP at 150 W versus 250 W, requires no external power connectors, and comes in an IGP form factor suited for portable systems. Its 82nd percentile ranking and higher average score (39,116 versus 36,530) mean it is the better overall performer in the aggregate, despite losing two of three individual tests.

Choose the NVIDIA GeForce GTX TITAN X if your work spans OpenCL, Vulkan, or memory-intensive tasks. Its 16.2% OpenCL lead and 23.2% Vulkan lead make it the stronger choice for cross-platform compute and modern graphics APIs. The 12 GB VRAM is a decisive advantage for workloads that exceed 4 GB, and the 336.6 GB/s bandwidth supports heavier texture throughput. The TITAN X also offers higher raw compute (6.691 TFLOPS versus 4.489 TFLOPS) and better DirectX support (12_1 versus 12_0), making it more future-proof for gaming and general compute. Its launch MSRP was 999 USD, reflecting its premium positioning.

For most users, the decision hinges on ecosystem: macOS and Metal users should take the Radeon Pro 575X; Windows or Linux users relying on OpenCL and Vulkan should take the GTX TITAN X. Neither card is universally superior, and the benchmark data supports a clear API-based split.
