AMD Radeon Pro Vega 16 vs NVIDIA GeForce RTX 2080 Comparison

# AMD Radeon Pro Vega 16 vs NVIDIA GeForce RTX 2080

The AMD Radeon Pro Vega 16 and NVIDIA GeForce RTX 2080 represent two vastly different approaches to GPU design, separated by architecture, process node, and intended use case. The data shows a decisive performance gap in head-to-head benchmarks, but the comparison is not without nuance—the Radeon Pro Vega 16 is an integrated-class part for portable Mac systems, while the RTX 2080 is a dual-slot desktop behemoth. Benchmark scores reveal the RTX 2080 dominates compute workloads, yet the AMD card holds its own in specific API tests relative to its power envelope. Here is the breakdown from the available benchmark data.

Head-to-Head Benchmarks

The head-to-head results are starkly one-sided, with the RTX 2080 winning both recorded tests by enormous margins. In Geekbench OpenCL, the RTX 2080 scores 91,313 against the Radeon Pro Vega 16's 18,268—a delta of -80%, meaning the AMD card delivers only one-fifth the raw compute throughput. The Vulkan test tells a nearly identical story: RTX 2080 posts 107,797 versus 21,832 for the Radeon Pro Vega 16, a -79.7% difference. These are not marginal gaps; they represent a generational and architectural chasm in raw processing power.

The RTX 2080's advantage stems from its hardware fundamentals. It packs 2,944 shading units, 184 texture mapping units, and 64 ROPs, against the Radeon Pro Vega 16's 1,024 shaders, 64 TMUs, and 32 ROPs. Pixel throughput is 109.4 GPixel/s versus 38.08 GPixel/s, and texture rate is 314.6 GTexel/s versus 76.16 GTexel/s. FP32 compute is even more lopsided: 10.07 TFLOPS for NVIDIA versus 2.437 TFLOPS for AMD. The RTX 2080 also features 46 RT cores and 368 tensor cores—hardware the AMD part lacks entirely—enabling ray tracing and AI-accelerated workloads.

Memory bandwidth is another chasm. The RTX 2080 uses 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s. The Radeon Pro Vega 16 has 4 GB of HBM2 on a 1024-bit bus, yielding 307.2 GB/s. While the AMD card's HBM2 provides respectable bandwidth for its class, the RTX 2080 still leads by roughly 46%. Clock speeds also favor NVIDIA: the RTX 2080 runs at 1515 MHz base and 1710 MHz boost, versus 815 MHz base and 1190 MHz boost for the Radeon Pro Vega 16.

However, the Radeon Pro Vega 16 is not without merit in context. Its average benchmark score of 23,250 places it in the 68th percentile of all GPUs—identical to the RTX 2080's 68th percentile, despite the RTX 2080's average score of 22,895. This parity in percentile ranking is remarkable given the head-to-head drubbing. The AMD card's nearest rivals include the NVIDIA P106-100 (23,249 average score, 0% delta) and the AMD Radeon RX 6600M (23,273, -0.1% delta), suggesting it sits in a competitive mid-range tier. The RTX 2080's nearest rivals are the Intel Arc B580 (23,021, -0.5% delta) and the AMD Radeon RX 580 2048SP (23,061, -0.7% delta), which are similarly clustered. This means that while the RTX 2080 crushes the Radeon Pro Vega 16 in raw compute, both cards occupy the same overall performance percentile when measured against the entire GPU landscape—evidence of how benchmark averaging can flatten extreme differences.

The Verdict

The data is unambiguous: the RTX 2080 wins every head-to-head benchmark, and it wins by roughly 80% in both OpenCL and Vulkan. For any workload that demands maximum compute throughput—rendering, simulation, or high-end gaming—the RTX 2080 is the clear choice. Its 10.07 TFLOPS FP32 performance, 46 RT cores, and 368 tensor cores make it a far more capable part for modern graphics and compute tasks. The RTX 2080 also supports DirectX 12 Ultimate (12_2), while the Radeon Pro Vega 16 only reaches DirectX 12 (12_1), and NVIDIA's card supports Vulkan 1.4 versus AMD's 1.3.

That said, the Radeon Pro Vega 16 is not a failure—it's a different animal. With a 75 W TDP and integrated form factor (IGP slot width), it is designed for portable Mac systems where power efficiency and space are paramount. The RTX 2080, by contrast, is a 215 W dual-slot card requiring 1x 6-pin and 1x 8-pin power connectors, a 550 W suggested PSU, and measuring 267 mm in length. The AMD card needs no external power connectors and is portable-device dependent for display outputs. If the choice is between a thin-and-light laptop GPU and a desktop behemoth, the RTX 2080 wins on performance but loses on every practical metric of portability.

The verdict splits by use case. For desktop users prioritizing raw performance, the RTX 2080 is the only rational pick—its benchmark scores are simply in another league. For users who need a capable GPU in an integrated, low-power package, the Radeon Pro Vega 16 delivers respectable performance (68th percentile) without the bulk, power draw, or cooling requirements of a discrete card. The data does not support any scenario where the Radeon Pro Vega 16 outperforms the RTX 2080 in compute, but it does validate the AMD part as a competent solution for its intended niche.

Where Each One Wins

The RTX 2080 wins in every measurable performance category. OpenCL compute is 80% faster, Vulkan is 79.7% faster, and the card's specifications are uniformly superior: more shading units, more TMUs, more ROPs, higher clocks, more memory, and higher bandwidth. It also wins on API support, offering DirectX 12 Ultimate and Vulkan 1.4, which future-proofs it for newer titles and applications. The RTX 2080's RT and tensor cores give it a unique advantage in ray-traced rendering and AI inference workloads—capabilities the Radeon Pro Vega 16 cannot match at all.

The Radeon Pro Vega 16 wins on power efficiency and form factor. Its 75 W TDP is less than a third of the RTX 2080's 215 W, and its IGP slot width means it can be integrated directly into a laptop motherboard. It requires no external power connectors, while the RTX 2080 needs both a 6-pin and an 8-pin. The AMD card's HBM2 memory, while smaller in capacity (4 GB vs 8 GB), offers a wider 1024-bit bus, which can be advantageous in bandwidth-sensitive tasks that fit within its capacity. The Radeon Pro Vega 16 also supports OpenGL 4.6 and Vulkan 1.3, which is sufficient for most professional and consumer workloads.

In the nearest-rival context, the Radeon Pro Vega 16 sits within 0.3% of the AMD Radeon AI PRO R9700 (23,315 average score, -0.3% delta) and essentially ties the NVIDIA P106-100 (23,249, 0% delta). The RTX 2080, meanwhile, is within 1.2% of the NVIDIA GeForce RTX 3080 (23,172, -1.2% delta), showing it holds its own against newer hardware. This suggests the RTX 2080 is a more future-proof investment, while the Radeon Pro Vega 16 is strictly a contemporary solution.
