AMD Radeon Pro Vega 64 vs AMD Radeon RX 7600M Comparison

AMD Radeon Pro Vega 64 and AMD Radeon RX 7600M represent two very different eras of AMD GPU design, and the benchmark data reflects a clear split that favors the older card in raw compute while the newer part counters with architectural efficiency. The single available head-to-head benchmark, Geekbench OpenCL, shows the Radeon Pro Vega 64 scoring 71,094 against the RX 7600M’s 63,775, a decisive 11.5% advantage. This is not a marginal win; it places the Pro Vega 64 in the 91st percentile of all GPUs, while the RX 7600M sits at the 89th percentile, a two-point gap that understates the performance delta in this specific workload.

Head-to-Head Benchmarks

The only direct comparison available is Geekbench OpenCL, and the Radeon Pro Vega 64 wins it outright. Its score of 71,094 beats the RX 7600M’s 63,775, yielding an 11.5% margin. That is a substantial lead for a GPU that is six years older in release timing, and it stems from the Pro Vega 64’s sheer compute resources: 4,096 shading units against 1,792, and 256 texture mapping units versus 112. The Pro Vega 64 also posts 11.06 TFLOPS of FP32 throughput, while the RX 7600M reaches 17.27 TFLOPS, yet the older card still wins the OpenCL test. This suggests that raw shader count and memory bandwidth matter more in this benchmark than peak FLOPs, as the Pro Vega 64’s 402.4 GB/s bandwidth dwarfs the RX 7600M’s 256.0 GB/s.

The delta becomes more telling when placed against each card’s nearest rivals. The Pro Vega 64 sits just 0.4% above the NVIDIA TITAN X Pascal (average score 72,098) and 0.9% above the AMD Radeon RX 6650M (71,768). It trails the Vega Frontier Edition by 1.4% (73,370) and beats the RX 6600 LE by 2.2% (70,829). The RX 7600M, by contrast, is nearly dead-even with the RX 9060 XT LP (63,830, -0.1%) and the NVIDIA CMP 30HX (63,842, -0.1%), while edging out the Radeon Pro Vega 56 by 0.1% (63,693) and falling 0.7% short of the Radeon Pro WX 9100 (64,212). What this means is that the Pro Vega 64 competes at a tier roughly 11% higher than the RX 7600M in OpenCL, a gap that aligns with its higher percentile ranking and larger memory subsystem.

Where Each One Wins

The Radeon Pro Vega 64 wins the compute-heavy OpenCL benchmark, and that is its only confirmed victory in the data. It achieves this through a 2048-bit memory bus and 16 GB of HBM2, which provides 402.4 GB/s of bandwidth. That bandwidth is critical for workloads that stream large datasets, such as rendering or scientific compute, where the RX 7600M’s 128-bit GDDR6 bus at 256.0 GB/s would become a bottleneck. The Pro Vega 64 also has 64 ROPs, matching the RX 7600M, but its higher texture rate of 345.6 GTexel/s versus 269.9 GTexel/s gives it an edge in texture-heavy scenes. Its pixel rate, however, is lower at 86.40 GPixel/s against 154.2 GPixel/s, meaning the RX 7600M would win in pure fill-rate-bound scenarios.

The RX 7600M’s wins are structural rather than measured in the provided benchmarks. It has a higher boost clock at 2410 MHz versus 1350 MHz, and a game clock of 2070 MHz that the Pro Vega 64 lacks entirely. Its FP32 throughput of 17.27 TFLOPS is 56% higher than the Pro Vega 64’s 11.06 TFLOPS, which suggests it would win in compute tasks that scale perfectly with shader count and clock speed, provided memory bandwidth is not the limiting factor. The RX 7600M also supports ray tracing with 28 RT cores, a feature the Pro Vega 64 does not have. For gaming, the RX 7600M’s higher pixel rate and modern architecture would likely deliver better framerates in rasterized titles, though no gaming benchmark is present in the data to confirm this.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The Radeon Pro Vega 64 uses the Vega 10 chip on GCN 5.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 12,500 million transistors into a 495 mm² die, yielding a transistor density of 25.3 million per square millimeter. The RX 7600M uses the Navi 33 chip on RDNA 3.0 architecture, built on a 6 nm process at TSMC. It contains 13,300 million transistors on a 204 mm² die, achieving a far higher density of 65.2 million per square millimeter. This density difference explains why the RX 7600M can deliver higher clock speeds and better power efficiency despite having fewer physical resources.

Memory configuration is another major split. The Pro Vega 64 has 16 GB of HBM2 on a 2048-bit bus, providing 402.4 GB/s bandwidth at 1572 Mbps effective memory speed. The RX 7600M has 8 GB of GDDR6 on a 128-bit bus, with 256.0 GB/s bandwidth at 16 Gbps effective. The Pro Vega 64’s memory bandwidth is 57% higher, but the RX 7600M’s GDDR6 is faster per pin, which is why it can achieve competitive performance with a quarter of the bus width. The Pro Vega 64 also has a base clock of 1250 MHz and boost of 1350 MHz, while the RX 7600M starts at 1500 MHz and boosts to 2410 MHz, with a game clock of 2070 MHz.

Feature support diverges sharply. The RX 7600M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro Vega 64 is limited to DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The RX 7600M’s ray tracing cores (28) are absent on the Pro Vega 64, and the RX 7600M uses PCIe 4.0 x16 versus PCIe 3.0 x16. Power consumption is a stark difference: the Pro Vega 64 has a TDP of 250 W, while the RX 7600M draws only 90 W. That 160 W gap translates to the RX 7600M being far more suitable for mobile form factors, as both are listed as IGP (integrated graphics processor) with portable-device-dependent outputs and no power connectors.

The Verdict

The data points to a clear choice for compute-centric users: the Radeon Pro Vega 64. Its 11.5% OpenCL lead over the RX 7600M is backed by 57% more memory bandwidth, double the shading units, and a 91st-percentile ranking. For anyone running OpenCL workloads, scientific simulations, or large texture datasets, the Pro Vega 64 is the superior performer despite being end-of-life. Its 16 GB of HBM2 is also a practical advantage for memory-hungry applications.

The RX 7600M is the pick for modern workloads and efficiency. It delivers 17.27 TFLOPS, a 56% higher FP32 throughput than the Pro Vega 64, plus ray tracing support and DirectX 12 Ultimate. Its 90 W TDP versus 250 W makes it viable for thin-and-light laptops, while the Pro Vega 64’s 250 W draw is prohibitive outside of desktop-class integrated designs. The RX 7600M’s 89th percentile is only two points lower, and its architectural modernity means it will support newer APIs and features that the Pro Vega 64 cannot.

In short, the Pro Vega 64 wins the only benchmark we have, but the RX 7600M wins on architecture. Choose the Pro Vega 64 for raw compute bandwidth and legacy performance; choose the RX 7600M for efficiency, ray tracing, and forward-looking feature support. The 11.5% performance gap is real, but so is the 160 W power difference — and that trade-off defines these two cards.
