AMD Radeon Pro Vega 16 vs AMD Radeon RX 7900 XTX Comparison

AMD Radeon Pro Vega 16 and AMD Radeon RX 7900 XTX occupy entirely different segments of the GPU landscape, and the recorded benchmark data reflects a decisive split between them. The RX 7900 XTX wins both direct comparisons by massive margins, while the Pro Vega 16 holds a higher overall percentile ranking among all GPUs due to the broader mix of tests in the database. The data shows a clear generational and architectural chasm, with the RX 7900 XTX delivering 176% higher OpenCL scores and 292% higher Vulkan scores in head-to-head testing.

Where Each One Wins

The AMD Radeon RX 7900 XTX dominates every recorded benchmark category where both cards have direct comparisons. In the two head-to-head tests, it wins both: Geekbench OpenCL and Geekbench Vulkan. The OpenCL result of 50465 against 18268 represents a 63.8% advantage for the RX 7900 XTX, while the Vulkan result of 85612 against 21832 shows a 74.5% lead. These are not marginal wins; they are outright routs that point to the RX 7900 XTX being in a completely different performance class.

The AMD Radeon Pro Vega 16, however, does not win any direct comparison in the head-to-head dataset. Its wins, if they can be called that, appear only in the context of its aggregate average benchmark score. The Pro Vega 16 has an average benchmark score of 23250, while the RX 7900 XTX has an average of 19410. This inversion occurs because the database includes a wider range of tests for the RX 7900 XTX, including several Passmark tests with low scores (DirectX 9 at 330, DirectX 10 at 166, DirectX 11 at 356, DirectX 12 at 131), which drag down its average. The Pro Vega 16 only has three recorded benchmarks, all Geekbench tests, so its average is based on a narrower, higher-performing set.

For use-case selection, the RX 7900 XTX is the clear choice for any modern workload that leverages Vulkan or OpenCL, particularly gaming, compute, and content creation. The Pro Vega 16, with its 68th percentile ranking versus the RX 7900 XTX’s 64th percentile, appears better suited only for legacy or specific Mac-centric workloads where its HBM2 memory and integrated design matter more than raw throughput.

Architecture Differences

The architectural gap between these two GPUs is substantial. The Pro Vega 16 uses the Vega 12 chip on a 14 nm process from GlobalFoundries, built on GCN 5.0 architecture. It belongs to the Radeon Pro Mac generation, specifically the Vega Series. The RX 7900 XTX uses the Navi 31 chip on a 5 nm process from TSMC, built on RDNA 3.0 architecture, with the codename Plum Bonito and a generation label of Navi III (RX 7000).

The transistor counts tell the story of scale. The RX 7900 XTX has 57,700 million transistors on a 529 mm² die, with a transistor density of 109.1M per mm². The Pro Vega 16 has no recorded transistor count or die size in the database, but its 14 nm process suggests a far smaller and denser design. The shading unit count is a stark differentiator: the RX 7900 XTX has 6144 shading units, 384 texture mapping units, and 192 raster operations pipelines, while the Pro Vega 16 has 1024 shading units, 64 TMUs, and 32 ROPs. The RX 7900 XTX also includes 96 ray tracing cores, a feature entirely absent from the Pro Vega 16.

Memory architecture differs fundamentally. The Pro Vega 16 uses 4 GB of HBM2 on a 1024-bit bus, delivering 307.2 GB/s of bandwidth. The RX 7900 XTX uses 24 GB of GDDR6 on a 384-bit bus, delivering 960.0 GB/s. The RX 7900 XTX has a 384-bit bus width, while the Pro Vega 16 has a wider 1024-bit bus, but the actual bandwidth advantage goes to the RX 7900 XTX due to its faster memory clock (2500 MHz versus 1200 MHz). The RX 7900 XTX also supports PCIe 4.0 x16, while the Pro Vega 16 is limited to PCIe 3.0 x16.

Head-to-Head Benchmarks

The two direct comparisons in the database are both Geekbench tests, and both show the RX 7900 XTX winning by enormous margins. In Geekbench OpenCL, the RX 7900 XTX scores 50465, while the Pro Vega 16 scores 18268. The delta percentage is 63.8%, meaning the RX 7900 XTX is 63.8% faster than the Pro Vega 16 in this test. This is a compute-oriented workload, and the RX 7900 XTX’s 61.39 TFLOPS of FP32 performance versus the Pro Vega 16’s 2.437 TFLOPS explains the gap. The RX 7900 XTX delivers roughly 25 times the raw floating-point throughput, and the benchmark reflects that scale.

In Geekbench Vulkan, the RX 7900 XTX scores 85612, while the Pro Vega 16 scores 21832. The delta percentage is 74.5%, an even larger gap than OpenCL. Vulkan is a modern graphics and compute API, and the RX 7900 XTX’s RDNA 3.0 architecture, with its ray tracing cores and 96 dedicated units, provides hardware features that the GCN 5.0-based Pro Vega 16 simply lacks. The RX 7900 XTX also supports DirectX 12 Ultimate (12_2), whereas the Pro Vega 16 only supports DirectX 12 (12_1), which limits its feature set in newer titles.

The RX 7900 XTX also has additional benchmark results beyond the head-to-head set. Its Passmark G3D score is 31238, its Passmark GPU Compute score is 17689, and its Passmark G2D score is 1267. These scores, while not directly comparable to any Pro Vega 16 result, indicate strong performance across legacy and modern graphics tests. The Pro Vega 16, by contrast, has no Passmark results in the database, only the three Geekbench tests.

The Verdict

The data is unambiguous: the AMD Radeon RX 7900 XTX is the superior performer in every direct comparison. It wins both head-to-head benchmarks with margins of 63.8% and 74.5%, and its raw specifications dwarf the Pro Vega 16 across the board. Anyone selecting between these two for modern gaming, compute, or content creation should choose the RX 7900 XTX based on the recorded results.

The AMD Radeon Pro Vega 16, however, holds a higher percentile ranking among all GPUs at 68% versus the RX 7900 XTX’s 64%. This suggests that in the broader database context, the Pro Vega 16 performs better relative to its contemporaries than the RX 7900 XTX does relative to its own generation. But this is a statistical artifact of the test set, not a real performance advantage. The Pro Vega 16’s only three benchmarks are all Geekbench tests, which tend to score well on this card, while the RX 7900 XTX’s ten benchmarks include several Passmark tests that pull its average down.

For users who need a low-power integrated solution, the Pro Vega 16’s 75 W TDP and IGP form factor are notable. It requires no external power connectors and is designed for portable devices. The RX 7900 XTX, by contrast, demands a 750 W power supply and dual-slot cooling, making it a desktop-only component. The Pro Vega 16 also uses HBM2 memory, which is a different technology from the RX 7900 XTX’s GDDR6, but the practical bandwidth advantage belongs entirely to the RX 7900 XTX.

The verdict is straightforward. The RX 7900 XTX is the choice for anyone prioritizing performance, with 24 GB of memory, 96 ray tracing cores, and a 5 nm process delivering 61.39 TFLOPS of FP32 compute. The Pro Vega 16 is the choice only for specialized, low-power, integrated applications where its 4 GB HBM2 and 75 W TDP fit a specific niche. In every recorded benchmark, the RX 7900 XTX wins, and by a wide margin. The Pro Vega 16’s higher percentile ranking does not translate into any actual benchmark victory, making the RX 7900 XTX the clear recommendation from the data.
