AMD Radeon Pro Vega 20 vs NVIDIA GeForce RTX 3070 Ti Mobile Comparison

The AMD Radeon Pro Vega 20 and the NVIDIA GeForce RTX 3070 Ti Mobile occupy different corners of the mobile GPU landscape. The recorded data shows a decisive performance gap between them, with the NVIDIA part leading in every shared benchmark metric. This analysis breaks down the head-to-head results, architecture differences, and use-case implications based strictly on the database measurements.

Head-to-Head Benchmarks

The database contains two directly comparable benchmark results for these GPUs: Geekbench OpenCL and Geekbench Vulkan. In both tests, the NVIDIA GeForce RTX 3070 Ti Mobile delivers a commanding victory over the AMD Radeon Pro Vega 20.

In Geekbench OpenCL, the RTX 3070 Ti Mobile scores 106,022, while the Radeon Pro Vega 20 scores 26,679. This represents a delta of -74.8% for the AMD part, meaning the NVIDIA GPU is roughly four times faster in this compute workload. The margin is immense, and it reflects the fundamental differences in compute throughput between the two designs.

The Geekbench Vulkan result tells a similar story. The RTX 3070 Ti Mobile posts 100,027 points, versus 26,410 for the Radeon Pro Vega 20, a delta of -73.6%. Again, the NVIDIA GPU leads by nearly 3.8x. Both benchmarks are compute-oriented, but Vulkan also exercises graphics and driver efficiency, and the NVIDIA part dominates there as well.

Looking beyond the head-to-head, the average benchmark scores in the database reinforce this hierarchy. The Radeon Pro Vega 20 has an average benchmark score of 27,839, while the RTX 3070 Ti Mobile averages 23,518. Note that these averages are not directly comparable because they include different test suites, but the percentile rankings provide context. The AMD GPU sits at the 73rd percentile of all GPUs, while the NVIDIA part sits at the 69th percentile. This suggests that while the RTX 3070 Ti Mobile wins the specific tests where both are present, its overall benchmark mix includes some weaker results, likely from older DirectX or compute tests that do not favor its architecture.

The nearest rivals in the database also clarify the positioning. The Radeon Pro Vega 20 is flanked by the AMD Radeon RX 7800M (delta -0.2%), the Radeon Pro W5500X (-0.5%), the GeForce GTX 980 Ti (-0.6%), and the GeForce RTX 3090 (+1%). This places the Vega 20 in a cluster of GPUs that are roughly equivalent in average score, despite the RTX 3090 being a much larger desktop part. The RTX 3070 Ti Mobile, by contrast, sits near the RTX 3080 Mobile (-0.5%), the AMD Radeon AI PRO R9700 (+0.9%), the GTX TITAN Z (-0.9%), and the Radeon R9 M290X (+1%). The mobile NVIDIA GPU is grouped with other high-end laptop and workstation parts, indicating a different performance tier.

The wins tally is unambiguous: the RTX 3070 Ti Mobile wins 2 benchmarks, the Radeon Pro Vega 20 wins 0. No shared test shows the AMD part ahead, and the deltas are so large that no single workload in the database would favor the Vega 20.

The Verdict

The data points to a clear conclusion: the NVIDIA GeForce RTX 3070 Ti Mobile is the superior GPU in compute and graphics performance. In every benchmark where both GPUs appear, the NVIDIA part leads by a factor of roughly 3.7 to 4.0. The Radeon Pro Vega 20, while not a weak GPU when compared to its own nearest rivals, cannot match the raw throughput of the Ampere-based mobile part.

Who should pick the RTX 3070 Ti Mobile? Anyone whose workload prioritizes raw compute performance, modern graphics features, or high frame rates. The 74.8% and 73.6% deltas in OpenCL and Vulkan, respectively, show that the NVIDIA GPU is in a completely different performance class. The database also shows it supports DirectX 12 Ultimate, which is a feature set the Vega 20 lacks.

Who should pick the Radeon Pro Vega 20? The data suggests a very narrow set of circumstances. If a user is constrained to a system with a 100 W TDP and integrated graphics form factor (IGP), the Vega 20 fits that envelope. The RTX 3070 Ti Mobile has a 115 W TDP, so it is slightly more power-hungry. However, the performance gap is so large that the power savings are unlikely to justify the loss in computing capability.

The percentile rankings complicate a simple verdict. The Vega 20 sits at the 73rd percentile, higher than the RTX 3070 Ti Mobile’s 69th percentile. This means that across the entire GPU landscape, the Vega 20 performs better relative to the full database than the NVIDIA mobile part does. But this is an artifact of the benchmark suites each GPU is subjected to. The Vega 20’s average score of 27,839 is based on three Geekbench tests, all of which are compute-heavy. The RTX 3070 Ti Mobile’s average of 23,518 includes PassMark tests, some of which score low (e.g., PassMark DirectX 12 at 73, PassMark DirectX 10 at 124). These low scores drag down the average despite the GPU’s strong Geekbench and 3DMark results.

Thus, the verdict is straightforward: the RTX 3070 Ti Mobile is the better GPU for any task that leverages its compute and graphics capabilities. The Vega 20 is only preferable in a constrained system where power and form factor are paramount, and even then, the performance penalty is severe.

Architecture Differences

The two GPUs are built on fundamentally different architectures, which explains the performance gap. The AMD Radeon Pro Vega 20 uses the Vega 12 chip, based on the GCN 5.0 architecture, manufactured on a 14 nm process at GlobalFoundries. The NVIDIA GeForce RTX 3070 Ti Mobile uses the GA104 chip, based on the Ampere architecture, manufactured on an 8 nm process at Samsung.

The process node difference is significant: 14 nm versus 8 nm. This allows the NVIDIA chip to pack 17,400 million transistors into a 392 mm² die, with a transistor density of 44.4M per mm². The AMD chip’s transistor count and die size are not recorded in the database, but the older 14 nm node and smaller die are implied by its lower specifications.

Core counts differ massively. The Vega 20 has 1,280 shading units, 80 texture mapping units, and 32 raster output units. The RTX 3070 Ti Mobile has 5,888 shading units, 184 TMUs, and 96 ROPs. The NVIDIA GPU also includes 46 ray tracing cores and 184 tensor cores, which are absent from the AMD part entirely. These dedicated cores enable hardware-accelerated ray tracing and AI-based features, neither of which the Vega 20 supports.

Memory architecture is another major divergence. The Vega 20 uses 4 GB of HBM2 on a 1024-bit bus, delivering 189.4 GB/s of bandwidth. The RTX 3070 Ti Mobile uses 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s. Despite the narrower bus, the NVIDIA GPU’s higher memory clock (14 Gbps effective versus 1480 Mbps effective) and larger capacity give it more than double the bandwidth. The Vega 20’s HBM2 is a legacy choice from a time when high-bandwidth memory was a differentiator, but the GDDR6 implementation in the Ampere part is more practical and faster.

Clock speeds also favor the NVIDIA GPU. The Vega 20 has a base clock of 815 MHz and a boost of 1283 MHz. The RTX 3070 Ti Mobile has a base of 915 MHz and a boost of 1410 MHz. Higher clocks, combined with more cores, yield vastly higher fill rates and throughput. The pixel rate is 41.06 GPixel/s for the AMD part versus 135.4 GPixel/s for the NVIDIA part. The texture rate is 102.6 GTexel/s versus 259.4 GTexel/s. FP32 compute is 3.284 TFLOPS versus 16.60 TFLOPS, a fivefold difference.

Power consumption is one area where the AMD part is more modest. The Vega 20 has a TDP of 100 W, while the RTX 3070 Ti Mobile is rated at 115 W. The Vega 20 is also listed as an integrated graphics package (IGP), meaning it is designed to be soldered into a system, whereas the RTX 3070 Ti Mobile is a discrete mobile part with no power connectors listed.

API support differs as well. The Vega 20 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The RTX 3070 Ti Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The higher DirectX version and Vulkan version on the NVIDIA part indicate newer feature support, including ray tracing and mesh shaders.

The bus interface also differs: the Vega 20 uses PCIe 3.0 x16, while the RTX 3070 Ti Mobile uses PCIe 4.0 x16. This affects data transfer speeds between the GPU and the host system.

Release dates are far apart: the Vega 20 launched on November 13, 2018, while the RTX 3070 Ti Mobile launched on January 3, 2022. Both are marked as end-of-life in the database.

Where Each One Wins

Based strictly on the recorded data, the RTX 3070 Ti Mobile wins in every measurable performance category. It has higher clock speeds, more shading units, more TMUs, more ROPs, more memory, more bandwidth, and higher fill rates. It wins both Geekbench tests by margins exceeding 70%. It also supports newer APIs, including DirectX 12 Ultimate and Vulkan 1.4.

The Radeon Pro Vega 20 has no benchmark wins in the database. Its only advantages are qualitative: a lower TDP (100 W versus 115 W), an integrated form factor (IGP) that may fit in smaller systems, and an older release date that implies legacy compatibility. In a use case where power draw is strictly capped at 100 W and a discrete GPU is not an option, the Vega 20 is the only choice. But for any workload that uses OpenCL or Vulkan, the RTX 3070 Ti Mobile is overwhelmingly faster.

The average benchmark scores provide a nuance. The Vega 20’s average of 27,839 is higher than the RTX 3070 Ti Mobile’s 23,518, and its 73rd percentile rank exceeds the NVIDIA part’s 69th. This means that in the broader database, the Vega 20 is closer to its nearest rivals than the RTX 3070 Ti Mobile is to its own. However, this does not translate into a win in any direct comparison. The nearest rival data for the Vega 20 shows it within 1% of several GPUs, while the RTX 3070 Ti Mobile is also within 1% of its nearest rivals, but those rivals are themselves faster or slower in different ways.

For users, the use-case split is stark. Choose the RTX 3070 Ti Mobile for compute-heavy tasks, modern gaming with ray tracing, or any application that benefits from tensor cores. Choose the Radeon Pro Vega 20 only if the system must stay within a 100 W power envelope and the integrated form factor is a hard requirement. The performance penalty for that choice is severe, as the deltas of -74.8% and -73.6% make clear.
