AMD Radeon Pro 575X vs AMD Radeon RX 7650 GRE Comparison

The AMD Radeon RX 7650 GRE and AMD Radeon Pro 575X are two GPUs from different eras and design goals. The RX 7650 GRE is a recent RDNA 3.0 part aimed at consumer desktop gaming, while the Pro 575X is an older GCN 4.0 chip built for Apple Mac systems. Benchmark data shows a decisive performance gap, but the differences go far beyond raw speed.

Head-to-Head Benchmarks

The only shared benchmark between the two cards is Geekbench OpenCL, and the result is lopsided. The RX 7650 GRE scores 83109, while the Pro 575X manages 34773. That works out to a 139% delta in favor of the RX 7650 GRE. In practical terms, the newer card delivers more than double the compute throughput in this general-purpose workload. The RX 7650 GRE wins the sole head-to-head test, with a 1-0 record.

Context from the broader benchmark database reinforces this gap. The RX 7650 GRE sits at the 83rd percentile among all GPUs, with an average benchmark score of 42723. Its nearest rivals include the NVIDIA GeForce RTX 4070 SUPER at 43223 (-1.2%), the NVIDIA Quadro M6000 24 GB at 43262 (-1.2%), and the NVIDIA GeForce RTX 5050 Mobile at 43268 (-1.3%). This places the RX 7650 GRE in the upper-midrange tier, trading blows with modern and recent high-end parts.

The Pro 575X, by contrast, holds the 82nd percentile with an average score of 39116. Its nearest rivals are the AMD Radeon Pro 580X at 38706 (delta +1.1%), the NVIDIA GeForce MX570 A at 38691 (+1.1%), the AMD Radeon Pro 575 at 39555 (-1.1%), and the NVIDIA RTX A500 Mobile at 39568 (-1.1%). While the percentile ranking is nearly identical, the raw average score difference is significant: 42723 versus 39116, a gap of roughly 9%. The RX 7650 GRE’s OpenCL result of 83109 is more than double the Pro 575X’s 34773, and the Pro 575X’s best result in any test is its Metal score of 44655, which is still far below the RX 7650 GRE’s OpenCL score.

The data shows that the RX 7650 GRE is not just faster; it is in a different performance class. The Pro 575X’s 4.489 TFLOPS FP32 throughput and 140.3 GTexel/s texture rate are dwarfed by the RX 7650 GRE’s 22.08 TFLOPS and 345.0 GTexel/s. In every metric that matters for compute and graphics, the newer card leads by a wide margin.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The RX 7650 GRE uses the RDNA 3.0 architecture with the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is fabricated on a 6 nm process at TSMC. The die contains 13,300 million transistors on a 204 mm² area, yielding a transistor density of 65.2M per mm².

The Pro 575X uses the older GCN 4.0 architecture with the Ellesmere chip. It is part of the Radeon Pro Mac (500X Series) generation and is built on a 14 nm process at GlobalFoundries. The die holds 5,700 million transistors across 232 mm², giving a density of 24.6M per mm². That means the RX 7650 GRE packs more than twice the transistors into a smaller physical die, a direct result of the node advantage.

The RX 7650 GRE also brings modern feature support. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and includes 32 ray tracing cores. The Pro 575X only supports DirectX 12 (12_0) and Vulkan 1.3, with no ray tracing hardware at all. Both cards support OpenGL 4.6, but the RX 7650 GRE’s newer API level and ray tracing capability are clear generational upgrades.

Memory technology differs as well. The RX 7650 GRE uses 8 GB of GDDR6 on a 128-bit bus, with memory clocked at 2250 MHz (18 Gbps effective) for 288.0 GB/s bandwidth. The Pro 575X uses 4 GB of GDDR5 on a wider 256-bit bus, with memory at 1695 MHz (6.8 Gbps effective) for 217.0 GB/s bandwidth. Despite the narrower bus, the RX 7650 GRE delivers 33% more bandwidth thanks to faster memory.

The shading units (2048) and TMUs (128) are identical, as is the 1:1 FP16 to FP32 ratio. The base and boost clocks are only listed for the RX 7650 GRE (1720 MHz base, 2695 MHz boost, 2350 MHz game clock); the Pro 575X has no clock data in the pack.

Where Each One Wins

The RX 7650 GRE wins on every measurable front in the data. Its strengths lie in modern gaming and compute workloads: 8 GB of GDDR6 memory, ray tracing support, DirectX 12 Ultimate, and a 6 nm process that enables high clock speeds (boost up to 2695 MHz). The 22.08 TFLOPS FP32 throughput makes it suitable for demanding rendering, GPU-accelerated productivity, and high-refresh-rate gaming at mainstream resolutions. Its dual-slot design and single 8-pin power connector fit standard desktop builds, and its 204 mm length is compact for most cases.

The Pro 575X has no benchmark wins in the head-to-head data. Its advantages are confined to form factor and specific platform fit. As an IGP with no power connectors and portable-device-dependent display outputs, it is designed for integration into Apple Mac systems where discrete power delivery and user-upgradability are not priorities. Its 150 W TDP is slightly lower than the RX 7650 GRE’s 170 W, but that is offset by far lower performance. The 256-bit memory bus is wider, but the slower GDDR5 memory negates any theoretical advantage, resulting in lower bandwidth. The Pro 575X also supports Vulkan 1.3, which is only one minor version behind the RX 7650 GRE’s 1.4.

For users with a Mac that requires a compatible Radeon Pro card, the Pro 575X is the only choice in this comparison. For anyone building or upgrading a PC, the RX 7650 GRE is the clear pick.

The Verdict

The data is unambiguous. The AMD Radeon RX 7650 GRE outperforms the AMD Radeon Pro 575X in the only shared benchmark by 139%, and its average benchmark score of 42723 is roughly 9% higher than the Pro 575X’s 39116. The RX 7650 GRE is a modern, active product with ray tracing, 8 GB of memory, and nearly 5 times the FP32 throughput. It targets the 83rd percentile of all GPUs, placing it alongside the NVIDIA GeForce RTX 4070 SUPER and RTX 5050 Mobile.

The Pro 575X is an end-of-life part from 2019, built on a 14 nm process with GCN 4.0 architecture. It lacks ray tracing, supports only DirectX 12 (not Ultimate), and has half the memory of the RX 7650 GRE. Its only practical use case is in legacy Apple Mac systems that specifically require a Radeon Pro 500X-series GPU.

If you are building a new desktop system or upgrading a PC, the RX 7650 GRE is the only sensible option. Its launch MSRP was 279 USD. If you are maintaining a Mac that needs a Pro 575X, the performance comparison is irrelevant because the RX 7650 GRE will not fit that platform. For all other scenarios, the RX 7650 GRE wins decisively on performance, features, and longevity. The Pro 575X’s lower TDP (150 W vs 170 W) and wider memory bus (256 bit vs 128 bit) do not compensate for the massive compute and bandwidth deficits. Choose the RX 7650 GRE for any new build; reserve the Pro 575X for legacy Mac repairs.
