Architecture Differences

The AMD Radeon Pro Vega 48 and the AMD Radeon RX 7650 GRE represent two distinct generations of GPU design from the same manufacturer. The Pro Vega 48 is built on the GCN 5.0 architecture using the Vega 10 chip, manufactured on a 14 nm process at GlobalFoundries. In contrast, the RX 7650 GRE uses the RDNA 3.0 architecture with the Navi 33 chip, produced on a 6 nm process at TSMC. This process node difference is substantial, with the RX 7650 GRE achieving a transistor density of 65.2 million per mm² versus 25.3 million per mm² for the Pro Vega 48. The die sizes reflect this: the Vega 10 chip measures 495 mm² with 12,500 million transistors, while the Navi 33 die is only 204 mm² but packs 13,300 million transistors.

The architectural shift from GCN to RDNA brings fundamental changes to the compute pipeline. The Pro Vega 48 has 3072 shading units, 192 texture mapping units, and 64 ROPs. The RX 7650 GRE has fewer shading units at 2048 and fewer TMUs at 128, but it also has 64 ROPs. The RDNA 3.0 design introduces 32 dedicated ray tracing cores, a feature entirely absent from the Vega 10 architecture. This is a critical functional difference, as the RX 7650 GRE supports DirectX 12 Ultimate (12_2), while the Pro Vega 48 only reaches DirectX 12 (12_1). The Vulkan support also differs, with the RX 7650 GRE supporting Vulkan 1.4 versus 1.3 on the Pro Vega 48.

Memory technology represents another major architectural divergence. The Pro Vega 48 uses HBM2 memory with a 2048-bit bus, delivering 402.4 GB/s of bandwidth. The RX 7650 GRE uses GDDR6 with a 128-bit bus and 288.0 GB/s. Both cards have 8 GB of memory, but the HBM2 implementation on the Vega card provides substantially higher bandwidth despite the older architecture. The memory clock rates differ as well: the Pro Vega 48 runs at 786 MHz (1572 Mbps effective), while the RX 7650 GRE runs at 2250 MHz (18 Gbps effective).

The power delivery and physical design also reflect their different positioning. The Pro Vega 48 is listed as an IGP (integrated graphics processor) with no power connectors and no TDP listed, while the RX 7650 GRE is a dual-slot card with a 170 W TDP, requiring one 8-pin power connector and a suggested 450 W PSU. The Pro Vega 48 uses PCIe 3.0 x16, while the RX 7650 GRE uses PCIe 4.0 x8.

The Verdict

The benchmark data paints a clear picture for different use cases. The AMD Radeon Pro Vega 48 has the higher average benchmark score at 60140 versus 42723 for the RX 7650 GRE, and it sits in the 88th percentile of all GPUs compared to the 83rd percentile for the RX 7650 GRE. However, the RX 7650 GRE wins the only head-to-head benchmark recorded, the Geekbench OpenCL test, by a 35.3% margin. This suggests the Pro Vega 48's higher average score may be driven by different workload strengths across the benchmarks in its profile.

For users prioritizing raw compute in OpenCL workloads, the RX 7650 GRE is the clear choice based on the direct comparison. It also offers modern features that the Pro Vega 48 lacks entirely, including ray tracing cores and DirectX 12 Ultimate support. The RX 7650 GRE is an active product, while the Pro Vega 48 is end-of-life, which matters for ongoing driver support and availability. The RX 7650 GRE has a launch MSRP of 279 USD.

For users who need maximum memory bandwidth, the Pro Vega 48's HBM2 implementation with 402.4 GB/s is superior to the RX 7650 GRE's 288.0 GB/s. The Pro Vega 48 also has a wider 2048-bit memory bus, which can be advantageous in bandwidth-sensitive applications. The Pro Vega 48's higher overall average score and 88th percentile ranking suggest it excels in a broader range of recorded benchmarks, even though it loses the single direct comparison.

The RX 7650 GRE is the better choice for modern gaming and compute workloads that leverage RDNA 3.0 features, especially ray tracing and DirectX 12 Ultimate. The Pro Vega 48 may be preferable for legacy professional workloads that benefit from HBM2 bandwidth and the older GCN architecture, but its end-of-life status is a significant consideration. The data shows the RX 7650 GRE is the more future-proof option with active production status and a newer release date.

Head-to-Head Benchmarks

The database records one direct head-to-head benchmark between these two GPUs: the Geekbench OpenCL test. This is the definitive comparison point available, and the results are decisive. The AMD Radeon RX 7650 GRE scores 83109, while the AMD Radeon Pro Vega 48 scores 53757. The RX 7650 GRE wins by a 35.3% margin, a substantial gap in compute performance.

This OpenCL result is particularly notable because the Pro Vega 48 otherwise holds a higher average benchmark score across all recorded tests. The RX 7650 GRE's 83109 OpenCL score is dramatically higher than its own average of 42723, suggesting this card has exceptional compute throughput in OpenCL workloads compared to its performance in other benchmark categories. The Pro Vega 48's 53757 OpenCL score is closer to its 60140 average, indicating more consistent performance across its benchmark profile.

The RX 7650 GRE's FP32 performance of 22.08 TFLOPS versus the Pro Vega 48's 7.373 TFLOPS helps explain this OpenCL dominance. The RDNA 3.0 architecture delivers nearly three times the single-precision compute throughput. Additionally, the RX 7650 GRE achieves 22.08 TFLOPS in FP16 with a 1:1 ratio, while the Pro Vega 48 reaches 14.75 TFLOPS in FP16 with a 2:1 ratio. The RX 7650 GRE's higher clock speeds, with a boost clock of 2695 MHz, contribute directly to this compute advantage, as the Pro Vega 48 has no listed boost clock.

The RX 7650 GRE also leads in pixel and texture throughput. It achieves 172.5 GPixel/s and 345.0 GTexel/s, compared to 76.80 GPixel/s and 230.4 GTexel/s for the Pro Vega 48. These figures show that the RX 7650 GRE's pixel fill rate is more than double that of the Pro Vega 48, even though both have 64 ROPs. The texture rate advantage is also significant, with the RX 7650 GRE outpacing the Pro Vega 48 by a wide margin.

The Pro Vega 48 does maintain an advantage in memory bandwidth, with 402.4 GB/s versus 288.0 GB/s for the RX 7650 GRE. The 2048-bit HBM2 bus delivers substantially more bandwidth than the 128-bit GDDR6 bus on the RX 7650 GRE. This could benefit memory-intensive workloads, although the RX 7650 GRE's superior compute throughput appears to compensate in the recorded OpenCL test.

The nearest rivals for each GPU provide context for their relative positioning. The Pro Vega 48's closest competitor is the Intel Arc Pro A60 with a 0.3% difference in average score, followed by the NVIDIA GeForce RTX 4090 with the same 0.3% delta. The RX 7650 GRE's nearest rival is the NVIDIA GeForce RTX 4070 SUPER with a 1.2% delta, indicating the RX 7650 GRE sits in a similar performance tier to that card in the database's measurements. The RX 7650 GRE trails its nearest rivals by small margins, between 1.2% and 1.3%, while the Pro Vega 48 is essentially tied with its closest competitors and leads others by 2.5% to 2.8%.
