AMD Radeon Pro Vega 48 vs AMD Radeon RX 7600M Comparison

The AMD Radeon RX 7600M and the AMD Radeon Pro Vega 48 represent two distinct eras of mobile graphics, separated by a generational gap in architecture and manufacturing. The data shows a clear overall winner in raw compute, but the comparison reveals nuanced strengths for each GPU depending on the workload. The RX 7600M, built on the RDNA 3.0 architecture, delivers a decisive victory in the sole head-to-head OpenCL benchmark, while the Pro Vega 48, with its GCN 5.0 design, holds its own in specific API tests and maintains a competitive standing within its own benchmark percentile.

Head-to-Head Benchmarks

The only direct comparison available between these two GPUs is the Geekbench OpenCL test, and the results are stark. The AMD Radeon RX 7600M scores 63,775, while the AMD Radeon Pro Vega 48 trails significantly with a score of 53,757. This translates to an 18.6% advantage for the RX 7600M, a substantial margin that underscores the architectural efficiency of the newer RDNA 3.0 design over the older GCN 5.0 architecture. In this specific compute test, the RX 7600M is the unequivocal winner, demonstrating a significant leap in raw processing capability.

However, the Pro Vega 48 is not without its own competitive highlights. While it loses the OpenCL contest, its benchmark suite includes results from other APIs where it performs notably better. In the Geekbench Metal test, the Pro Vega 48 achieves a score of 69,010, which is significantly higher than its OpenCL score. This suggests that the GPU is highly optimized for Apple's Metal API, a key consideration for its target market of Mac users. Furthermore, its Geekbench Vulkan score of 57,653 also surpasses its OpenCL performance, indicating a strong showing in cross-platform graphics APIs.

Looking at the average benchmark scores paints a broader picture. The RX 7600M has an average score of 63,775, placing it in the 89th percentile of all GPUs. The Pro Vega 48, with an average of 60,140, sits just one percentile lower at 88. This close proximity in percentile ranking is interesting, given the large delta in the OpenCL test. The Pro Vega 48’s strong Metal and Vulkan scores likely boost its average, making it a more versatile performer across different software environments than its OpenCL result alone would suggest. In contrast, the RX 7600M shows consistency with a single, high OpenCL score, but its performance in other APIs is not documented in this data.

Where Each One Wins

The RX 7600M is the clear winner in general-purpose compute tasks as measured by OpenCL, a common benchmark for GPU acceleration. Its 18.6% lead over the Pro Vega 48 in this specific test is its primary victory. This suggests that for applications leveraging OpenCL for tasks like video rendering, scientific computing, or other non-graphics workloads, the RX 7600M will deliver superior performance. The data indicates this is a significant, not marginal, advantage.

The Pro Vega 48’s wins are more situational but equally clear. Its performance in the Geekbench Metal test is its strongest asset. With a score of 69,010, it outperforms its own OpenCL result by a considerable margin. This points to a GPU that is exceptionally well-tuned for the Metal framework, which is the standard for graphics and compute on Apple platforms. For users in a macOS environment, the Pro Vega 48 is likely the more performant option, despite its older architecture. Its Vulkan score of 57,653 also shows it is capable in that API, potentially offering an edge in Linux or other environments where Vulkan is preferred, although this cannot be directly compared to the RX 7600M, which lacks a Vulkan score in the data.

The architectural differences also hint at distinct use cases. The RX 7600M’s support for DirectX 12 Ultimate (12_2) makes it a more future-proof option for gaming, as it is designed to leverage the latest DirectX features. The Pro Vega 48, with its support for DirectX 12 (12_1), is one feature tier behind. Therefore, for a pure gaming workload on Windows, the RX 7600M is the logical choice, while the Pro Vega 48’s strengths lie in professional and creative applications that utilize Metal.

Architecture Differences

The two GPUs are built on fundamentally different architectures and manufacturing processes. The RX 7600M is based on the RDNA 3.0 architecture and uses the Navi 33 chip, which is fabricated on a 6 nm process at TSMC. This modern process allows for a high transistor density of 65.2M / mm², packing 13,300 million transistors into a relatively small 204 mm² die. In contrast, the Pro Vega 48 uses the older GCN 5.0 architecture with the Vega 10 chip, built on a 14 nm process at GlobalFoundries. This results in a much lower transistor density of 25.3M / mm², with 12,500 million transistors spread across a large 495 mm² die.

These process and architectural differences lead to major performance characteristics. The RX 7600M boasts a higher clock speed, with a boost clock of 2410 MHz, and delivers a massive 17.27 TFLOPS of FP32 compute power. The Pro Vega 48, with its older design, does not list a boost clock in the data and offers only 7.373 TFLOPS of FP32 performance. This more than 2x difference in compute throughput is a direct result of the architectural efficiency and clock speed advantages of RDNA 3.0.

Memory configurations also diverge sharply. The RX 7600M uses 8 GB of GDDR6 memory on a 128-bit bus, providing a bandwidth of 256.0 GB/s. The Pro Vega 48, however, uses 8 GB of HBM2 memory on a massive 2048-bit bus, which gives it a significantly higher bandwidth of 402.4 GB/s. This means the Pro Vega 48 can move data much faster, which can be beneficial for memory-intensive tasks, even if its raw compute is lower. The RX 7600M also features 28 ray-tracing cores, a hardware capability absent from the Pro Vega 48, which has no RT cores listed. This makes the RX 7600M a more capable GPU for real-time ray-traced workloads.
