AMD Radeon Pro 575X vs AMD Radeon RX 9070 XT Comparison

The AMD Radeon Pro 575X and the AMD Radeon RX 9070 XT represent two extremes of AMD’s graphics portfolio, separated by six years of architectural evolution. The data shows a stark contrast: the Pro 575X, a 2019 mobile workstation component, delivers an average benchmark score of 39,836, while the 2025 RX 9070 XT achieves 39,647. Despite the near-identical aggregate scores, the single head-to-head benchmark available paints a very different picture, with the RX 9070 XT winning decisively by 78.2%. This paradox—similar averages but wildly divergent raw performance—defines the comparison, making the choice between them entirely dependent on workload and context.

The Verdict

The AMD Radeon Pro 575X is the pick for legacy compatibility and specific mobile workstation environments. Its average score of 39,836 places it 0.5% ahead of the RX 9070 XT, a margin so thin it is statistically irrelevant. The Pro 575X also edges out the AMD Radeon RX Vega 64 by 0.1% and the AMD Radeon Pro 575 by 0.3%, showing it holds its own against older high-end parts. However, its 4 GB of GDDR5 memory and 217.0 GB/s bandwidth are severely limited by modern standards, and its DirectX 12 (12_0) support lacks the feature set of newer cards. This GPU is for users who need a drop-in replacement for a 2019-era Mac Pro, not for anyone seeking contemporary performance.

The AMD Radeon RX 9070 XT is the only rational choice for modern gaming and compute. Its single head-to-head result against the Pro 575X shows a crushing 78.2% victory in Geekbench OpenCL, with scores of 160,317 versus 35,017. The RX 9070 XT’s 48.66 TFLOPS of FP32 performance and 16 GB of GDDR6 memory at 644.6 GB/s are generational leaps. Its average score of 39,647 is dragged down by the inclusion of low-level DirectX 9 and 10 tests, where it scores 353 and 154 respectively—these legacy workloads favor older architectures. For any modern task, the RX 9070 XT is the definitive winner, and its launch MSRP of 599 USD reflects its positioning as a premium part.

Where Each One Wins

The Pro 575X wins on aggregate consistency. Its average benchmark score of 39,836 is higher than the RX 9070 XT’s 39,647, and it outperforms its nearest rival, the RX Vega 64, by 0.1%. This advantage comes from its simpler architecture posting solid scores across all tests without the dramatic swings seen in the newer card. The Pro 575X also wins on power efficiency relative to its output, with a 150 W TDP versus the RX 9070 XT’s 304 W, and it requires no external power connectors, making it suitable for IGP (integrated graphics processor) chassis designs.

The RX 9070 XT wins on every meaningful performance metric. Its Geekbench OpenCL score of 160,317 is 4.6 times higher than the Pro 575X’s 35,017. In PassMark G3D, it scores 26,795, and in GPU Compute it reaches 15,864. The RX 9070 XT also wins on memory capacity (16 GB vs 4 GB), bandwidth (644.6 GB/s vs 217.0 GB/s), and pixel rate (380.2 GPixel/s vs 35.07 GPixel/s). Its 64 ray tracing cores give it hardware RT capabilities that the Pro 575X lacks entirely. The RX 9070 XT’s texture rate of 760.3 GTexel/s is over five times the Pro 575X’s 140.3 GTexel/s, making it vastly superior for geometry-heavy scenes.

Architecture Differences

The architectural gap is immense. The Pro 575X uses the Ellesmere chip built on GlobalFoundries’ 14 nm process, packing 5,700 million transistors into a 232 mm² die with a density of 24.6M transistors per mm². Its GCN 4.0 architecture dates to 2016, and it was released in March 2019 as part of the Radeon Pro Mac (500X Series). It features 2,048 shading units, 128 TMUs, and 32 ROPs, with FP32 performance capped at 4.489 TFLOPS and FP16 at the same rate (1:1 ratio). It uses PCIe 3.0 x16 and supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3.

The RX 9070 XT is a radically different design. Its Navi 48 chip is fabricated on TSMC’s 4 nm process, containing 53,900 million transistors in a 357 mm² die—a density of 151.0M transistors per mm², over six times denser than the Pro 575X. Built on RDNA 4.0, it launched in March 2025 as part of the Navi IV (RX 9000) generation. It doubles the shader count to 4,096, doubles TMUs to 256, and quadruples ROPs to 128. It adds 64 ray tracing cores, a feature completely absent from the older card. FP32 performance jumps to 48.66 TFLOPS, and FP16 reaches 97.32 TFLOPS at a 2:1 ratio. The RX 9070 XT uses PCIe 5.0 x16, supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and has a boost clock of 2970 MHz versus the Pro 575X’s unspecified boost clock. Memory technology also differs: GDDR5 at 6.8 Gbps effective on the old card versus GDDR6 at 20.1 Gbps effective on the new one.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, and it is not close. The RX 9070 XT scores 160,317, while the Pro 575X manages just 35,017. This 78.2% delta is the largest single margin in this comparison and highlights the generational gap in compute throughput. The RX 9070 XT’s 48.66 TFLOPS of FP32 performance versus 4.489 TFLOPS on the Pro 575X explains this result—the newer card processes over ten times the floating-point operations per second.

The RX 9070 XT also dominates in memory-intensive tasks. Its 644.6 GB/s bandwidth is nearly three times the Pro 575X’s 217.0 GB/s, and its 16 GB capacity is quadruple the older card’s 4 GB. This means the RX 9070 XT can handle far larger datasets without spilling to system memory. The pixel rate advantage is similarly stark: 380.2 GPixel/s versus 35.07 GPixel/s, a 10.8x difference that translates directly to higher frame rates at high resolutions.

However, the Pro 575X is not without its own wins in the broader benchmark data. Its average score of 39,836 edges out the RX 9070 XT’s 39,647, and it outperforms the RX Vega 64 by 0.1%. This suggests that in certain legacy or driver-optimized workloads, the older GCN architecture remains competitive. The Pro 575X also has a 0.3% advantage over its direct predecessor, the Radeon Pro 575, showing incremental improvement within the same generation. In the aggregate, the Pro 575X is the 83rd percentile of all GPUs, while the RX 9070 XT sits at the 82nd percentile—statistically tied, but achieved through completely different means: consistency for the old card, raw peaks for the new one.
