AMD Radeon Pro 575 vs AMD Radeon RX 9070 XT Comparison

# AMD Radeon Pro 575 vs AMD Radeon RX 9070 XT

The AMD Radeon Pro 575 and AMD Radeon RX 9070 XT represent two vastly different eras of GPU design, separated by nearly eight years of architectural evolution. The Pro 575 is a mobile workstation part from 2017 built on GCN 4.0, while the RX 9070 XT is a 2025 desktop enthusiast card using RDNA 4.0. Despite their generational gap, the aggregate benchmark data places them remarkably close in average score—39,703 for the Pro 575 versus 39,647 for the RX 9070 XT—a difference of just 0.1%. However, this near-parity in aggregate masks a fundamental divergence in how each card performs across different workloads, with the RX 9070 XT delivering compute performance that utterly dwarfs the older part while the Pro 575's legacy status keeps it competitive only in the narrowest sense.

Head-to-Head Benchmarks

The head-to-head comparison available in the data covers only two compute-oriented tests, and in both, the RX 9070 XT delivers a crushing victory. In Geekbench OpenCL, the RX 9070 XT scores 160,317 against the Pro 575's 34,732, a delta of -78.3% from the RX 9070 XT's perspective—meaning the RX 9070 XT is roughly 4.6 times faster in raw compute throughput. The gap is even more pronounced in Geekbench Vulkan, where the RX 9070 XT posts 184,026 versus 38,204 for the Pro 575, a -79.2% delta that translates to nearly 4.8 times the performance. These are not incremental improvements; they represent a fundamental leap in compute capability that reflects the architectural and process-node advantages of the newer card.

What makes this head-to-head particularly striking is the contradiction it creates with the aggregate benchmark scores. The Pro 575's average of 39,703 across its three Geekbench tests (Metal, OpenCL, Vulkan) actually edges out the RX 9070 XT's average of 39,647 across a much broader suite of ten tests. This is because the Pro 575's Geekbench Metal score of 46,172 is not part of the head-to-head comparison, and the RX 9070 XT's aggregate is dragged down by a set of Passmark scores that are not directly comparable to the Pro 575's benchmark suite. The data shows that when both cards run the same OpenCL and Vulkan workloads, the RX 9070 XT wins decisively—but the Pro 575's Metal performance suggests it retains strengths in Apple-centric environments that the RX 9070 XT does not directly contest in this comparison.

The deltaPct values in the nearestRivals data further contextualize these results. The Pro 575's closest rival is the Pro 575X at -0.3% delta, meaning the Pro 575 performs 0.3% worse than its direct successor variant. The RX 9070 XT's nearest rival is the NVIDIA RTX A500 Mobile at 0.2% delta, indicating the RX 9070 XT is 0.2% faster than that mobile workstation card in aggregate—a surprisingly narrow margin given the RX 9070 XT's desktop-class specifications. Both cards sit within a tight cluster around the 39,500–39,900 average score range, suggesting that aggregate benchmarks in this database compress generational differences into a narrow band, while individual workload tests reveal the true magnitude of performance gaps.

Where Each One Wins

The RX 9070 XT wins in every head-to-head benchmark category that both cards share, and its advantage is overwhelming in compute-heavy workloads. Its Geekbench OpenCL score of 160,317 versus 34,732 for the Pro 575 makes it the clear choice for any OpenCL-accelerated application, from scientific computing to video encoding and rendering tasks that leverage GPU compute. Similarly, the Vulkan score of 184,026 versus 38,204 positions the RX 9070 XT as the superior option for Vulkan-based games and applications, which increasingly dominate modern PC gaming and professional visualization workloads. The RX 9070 XT's Passmark G3D score of 26,795 and Passmark GPU Compute score of 15,864 further reinforce its dominance in DirectX-based gaming and general compute tasks, though the Pro 575 has no comparable Passmark scores in the data for direct comparison.

The Pro 575's wins, however, are more nuanced and context-dependent. Its Geekbench Metal score of 46,172 is the only benchmark where it exceeds the RX 9070 XT's comparative performance—though the RX 9070 XT has no Metal score in the data, making a direct comparison impossible. The Pro 575's Metal capability, combined with its MXM module form factor and 150 W TDP, positions it as a specialized solution for portable workstations and Apple ecosystem applications where power efficiency and form factor compatibility matter more than raw compute. Its 83rd percentile ranking versus the RX 9070 XT's 82nd percentile shows that, despite the massive compute gap, the Pro 575 holds its own in the database's overall performance distribution—evidence of how well-optimized its GCN architecture remains for certain legacy workloads.

Where each card wins ultimately comes down to use case. The RX 9070 XT is the unequivocal winner for modern gaming, high-performance compute, and any application that can leverage its 48.66 TFLOPS of FP32 performance and 64 ray-tracing cores. The Pro 575, with its 4.489 TFLOPS FP32 and no ray-tracing support, wins only in scenarios where its Metal API support, MXM form factor, or 150 W power envelope are decisive factors—such as upgrading a legacy Mac Pro or a specialized embedded system where the RX 9070 XT's dual-slot, 304 W design simply cannot fit.

Architecture Differences

The architectural gulf between these two GPUs is the single most important factor explaining their performance divergence. The Pro 575 is built on GCN 4.0, an architecture that debuted in 2016 and was designed for the then-current generation of DirectX 12 and Vulkan workloads. It is fabricated on GlobalFoundries' 14 nm process with 5,700 million transistors on a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The RX 9070 XT, by contrast, uses the RDNA 4.0 architecture on TSMC's 4 nm process, packing 53,900 million transistors into a 357 mm² die for a density of 151.0 million per square millimeter—a six-fold increase in transistor density that enables dramatically higher performance within a comparable silicon footprint.

The compute resources scale accordingly. The Pro 575 features 2,048 shading units, 128 texture mapping units, and 32 raster operation units, with no dedicated ray-tracing or tensor cores. The RX 9070 XT doubles these counts to 4,096 shading units, 256 TMUs, and 128 ROPs, and adds 64 dedicated ray-tracing cores—a feature class that simply did not exist in the GCN 4.0 era. This translates to a pixel rate of 380.2 GPixel/s and a texture rate of 760.3 GTexel/s for the RX 9070 XT, versus 35.07 GPixel/s and 140.3 GTexel/s for the Pro 575. The FP32 throughput gap is even more stark: 48.66 TFLOPS for the RX 9070 XT versus 4.489 TFLOPS for the Pro 575.

Memory architecture differences are equally profound. The Pro 575 uses 4 GB of GDDR5 memory on a 256-bit bus, delivering 217.0 GB/s of bandwidth. The RX 9070 XT uses 16 GB of GDDR6 on the same 256-bit bus, but with a much higher memory clock of 2518 MHz (20.1 Gbps effective) that pushes bandwidth to 644.6 GB/s—a 3.0x improvement. The RX 9070 XT also supports FP16 at a 2:1 ratio (97.32 TFLOPS) versus the Pro 575's 1:1 ratio (4.489 TFLOPS), making the newer card substantially better suited for mixed-precision workloads. API support also diverges: the Pro 575 supports DirectX 12 (12_0) and Vulkan 1.3, while the RX 9070 XT supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, reflecting the newer card's hardware-level support for mesh shaders, variable-rate shading, and other DirectX 12 Ultimate features.

Specification Differences

The specification table reveals a systematic generational upgrade across nearly every measurable parameter. Clock speeds show the most dramatic shift: the Pro 575 has no listed base or boost clock, while the RX 9070 XT operates at a 1660 MHz base, 2400 MHz game clock, and 2970 MHz boost. Memory clocks jump from 1695 MHz (6.8 Gbps effective) on the Pro 575 to 2518 MHz (20.1 Gbps effective) on the RX 9070 XT, driving the bandwidth increase from 217.0 GB/s to 644.6 GB/s. Memory capacity quadruples from 4 GB to 16 GB, though both use a 256-bit bus.

Power and form factor differences are equally notable. The Pro 575 draws 150 W and comes as an MXM module with no power connectors, making it suitable for laptops and compact systems. The RX 9070 XT draws 304 W, requires two 8-pin power connectors, and recommends a 700 W power supply—a specification that places it firmly in desktop enthusiast territory. The bus interface also advances from PCIe 3.0 x16 to PCIe 5.0 x16, doubling the potential data transfer rate to the host system. Display outputs differ as well: the Pro 575's outputs are portable-device dependent, while the RX 9070 XT offers 1x HDMI 2.1b and 3x DisplayPort 2.1a.

Production status and release timing reflect the lifecycle gap. The Pro 575 was released on June 4, 2017, and is now end-of-life, with no listed predecessor or successor. The RX 9070 XT was released on March 5, 2025, remains active in production, and lists Navi III as its predecessor. The RX 9070 XT has a launch MSRP of 599 USD, which is the only pricing information available in the data. The Pro 575 has no launch MSRP listed. Both cards share the same OpenGL 4.6 support, but the RX 9070 XT's DirectX 12 Ultimate (12_2) and Vulkan 1.4 support surpass the Pro 575's DirectX 12 (12_0) and Vulkan 1.3.
