AMD Radeon Pro Vega 16 vs AMD Radeon R9 M290X Comparison

The AMD Radeon R9 M290X and AMD Radeon Pro Vega 16 are evenly matched in aggregate performance, with average benchmark scores of 23,276 and 23,250 respectively, a negligible 0.1% difference. However, their workload-specific behavior diverges sharply: the Pro Vega 16 dominates in Metal graphics tests, while the R9 M290X leads decisively in OpenCL compute. The verdict depends entirely on your software stack and platform, as these are not interchangeable parts.

The Verdict

For users on macOS with Metal-accelerated applications, the AMD Radeon Pro Vega 16 is the clear choice. Its Geekbench Metal score of 29,650 is a substantial 17.3% higher than the R9 M290X’s 24,524, making it the superior option for graphics-heavy tasks like video editing or 3D rendering that leverage Apple’s Metal API. The Pro Vega 16 also offers a more modern feature set with DirectX 12 (12_1) support and Vulkan 1.3, ensuring better longevity with current software.

For users running OpenCL workloads—common in scientific computing, data analysis, or cross-platform GPU compute—the AMD Radeon R9 M290X is unexpectedly stronger. Its OpenCL score of 22,028 beats the Pro Vega 16’s 18,268 by a commanding 20.6%. This is a counterintuitive result given the Pro Vega 16’s newer architecture and higher boost clock, but the benchmark data is unambiguous. If your primary driver is OpenCL performance, the older card wins.

In mixed workloads, the two cards are effectively tied. Both sit at the 68th percentile of all GPUs, with the R9 M290X’s nearest rival being the AMD Radeon RX 6600M (delta 0%) and the Pro Vega 16’s nearest rival being the NVIDIA P106-100 (delta 0%). Neither card offers a meaningful aggregate advantage; the deltaPct between them is just 0.1%, which is within noise. Choose based on API compatibility first, then consider power and platform constraints.

Architecture Differences

The architectural gap between these two GPUs is generational, yet the performance gap is not. The R9 M290X uses the Neptune chip built on GCN 1.0 architecture, manufactured on a 28 nm process at TSMC. It packs 2,800 million transistors into a 212 mm² die, yielding a transistor density of 13.2 million per square millimeter. The Pro Vega 16 uses the Vega 12 chip on GCN 5.0 architecture, built on a 14 nm process at GlobalFoundries; its transistor count and die size are not disclosed. The process node difference suggests the Pro Vega 16 should be more power-efficient, which the data confirms: the R9 M290X has a 100 W TDP, while the Pro Vega 16 draws 75 W.

The R9 M290X compensates for its older architecture with raw compute resources: 1,280 shading units, 80 texture mapping units, and 32 ROPs. The Pro Vega 16 has fewer of each—1,024 shading units, 64 TMUs, and 32 ROPs—but runs at a higher boost clock of 1,190 MHz versus the M290X’s 900 MHz. This clock advantage helps the Pro Vega 16 achieve higher pixel and texture rates: 38.08 GPixel/s and 76.16 GTexel/s, versus 28.80 GPixel/s and 72.00 GTexel/s for the M290X. In FP32 compute, the Pro Vega 16 edges ahead at 2.437 TFLOPS versus 2.304 TFLOPS, and it uniquely supports FP16 at 4.874 TFLOPS with a 2:1 ratio, which the M290X lacks entirely.

Memory architecture is where the two diverge most dramatically. The R9 M290X uses 4 GB of GDDR5 on a 256-bit bus, delivering 153.6 GB/s of bandwidth. The Pro Vega 16 uses 4 GB of HBM2 on a 1024-bit bus, delivering exactly double the bandwidth at 307.2 GB/s. This bandwidth advantage is likely why the Pro Vega 16 excels in Metal tests, which are often memory-bandwidth-sensitive. However, the Pro Vega 16’s memory clock is listed at 2.4 Gbps effective, while the M290X’s memory runs at 4.8 Gbps effective—the wider bus more than compensates.

Head-to-Head Benchmarks

The Geekbench Metal test produces the largest single margin between these cards. The Pro Vega 16 scores 29,650 versus the R9 M290X’s 24,524, a 17.3% delta in favor of the newer card. This is a decisive win that likely reflects the combination of higher boost clock, doubled memory bandwidth, and GCN 5.0 optimizations for Metal. For any macOS user running Metal-based software—whether it is Final Cut Pro, Blender’s Metal backend, or game engines—this margin translates into visibly faster rendering and smoother viewport performance.

The Geekbench OpenCL test flips the script entirely. The R9 M290X scores 22,028, beating the Pro Vega 16’s 18,268 by 20.6%. This is a remarkable result for a card from 2014 against a 2018 part. The M290X’s higher shading unit count (1,280 vs 1,024) and higher memory clock (4.8 Gbps effective vs 2.4 Gbps) may explain its OpenCL advantage, as OpenCL kernels often scale with raw shader throughput and memory speed rather than bus width alone. The Pro Vega 16’s lower base clock of 815 MHz (versus 850 MHz) may also hurt in sustained compute workloads that do not boost as aggressively.

Notably, the Pro Vega 16 has a Vulkan benchmark score of 21,832, while the R9 M290X has no Vulkan score listed. This is not a head-to-head comparison, but it indicates the Pro Vega 16 is tested and capable under Vulkan 1.3, whereas the M290X only supports Vulkan 1.2.170 and lacks a corresponding benchmark entry. For modern cross-platform games that use Vulkan, the Pro Vega 16 is the safer choice, though its Vulkan score is lower than its Metal score.

Where Each One Wins

The AMD Radeon R9 M290X wins in OpenCL compute workloads, delivering a 20.6% higher score (22,028 versus 18,268) than the Pro Vega 16. This makes it the better choice for users running OpenCL-based applications, such as certain scientific simulations, video encoding tools, or legacy compute pipelines that have not migrated to Metal or Vulkan. Its higher shading unit count (1,280) and faster memory clock (4.8 Gbps effective) appear to benefit this workload type. It also has a lower base clock (850 MHz versus 815 MHz), which may help in sustained compute scenarios where boost clocks are less reliable. However, its 100 W TDP is higher, and it lacks FP16 support entirely.

The AMD Radeon Pro Vega 16 wins in Metal graphics performance, with a 17.3% higher score (29,650 versus 24,524) than the R9 M290X. This is the dominant metric for macOS users, where Metal is the primary graphics API for professional applications and games. Its doubled memory bandwidth (307.2 GB/s versus 153.6 GB/s) and higher boost clock (1,190 MHz versus 900 MHz) drive this advantage. It also offers modern API support with DirectX 12 (12_1) and Vulkan 1.3, plus exclusive FP16 compute at 4.874 TFLOPS. At 75 W TDP, it is more power-efficient and designed as an IGP, making it suitable for thinner laptops where the M290X’s MXM module form factor would not fit. For any user prioritizing Metal performance, modern API compatibility, or lower power draw, the Pro Vega 16 is the unequivocal winner.
