AMD Radeon Pro Vega II vs NVIDIA RTX A4500 Mobile Comparison

Head-to-Head Benchmarks

The benchmark data splits decisively along API lines. In Geekbench OpenCL, the NVIDIA RTX A4500 Mobile takes a clear win with a score of 105307 against the AMD Radeon Pro Vega II’s 99048, a delta of -5.9% from AMD’s perspective. That 6,259-point gap is meaningful but not overwhelming; the AMD card still lands within striking distance in compute workloads that favor OpenCL. The Vulkan results, however, flip the script dramatically. The Radeon Pro Vega II scores 99621 versus the RTX A4500 Mobile’s 76960, giving AMD a 29.4% advantage — a commanding margin that dwarfs NVIDIA’s OpenCL lead. The average benchmark score across all tests reinforces this split: the AMD card averages 109617, while the NVIDIA card sits at 91134, a difference of roughly 20% in AMD’s favor.

Context from the nearest-rival comparisons adds nuance. The Radeon Pro Vega II’s average score of 109617 places it just 1% below the AMD Radeon PRO W7900 (110725) and 2.1% above the AMD Radeon Pro W6600X (107342). It also sits 2.7% above the dual-GPU Radeon Pro Vega II Duo (106750), which is notable — the single-GPU version outperforms its dual-chip sibling in this aggregate metric. The NVIDIA RTX A4500 Mobile, by contrast, averages 91134, which is 0.6% below the desktop RTX A4500 (91671) and 1.4% below the AMD Radeon Instinct MI60 (92466). It does beat the NVIDIA Quadro GP100 (87445) by 4.2% and the AMD Radeon PRO W7600 (87108) by 4.6%. These deltas are small, suggesting the RTX A4500 Mobile sits in a tight cluster of mid-to-high-end workstation GPUs, whereas the Radeon Pro Vega II competes with much stronger desktop parts.

The percentile rankings tell a similar story. The Radeon Pro Vega II sits in the 94th percentile of all GPUs, while the RTX A4500 Mobile is in the 93rd. That single-percentile gap may seem trivial, but the underlying scores differ by over 18,000 points on average. The Vulkan result is the single largest swing in the head-to-head data — a 29.4% edge that no other comparison in either card’s rival list comes close to matching. For OpenCL, the 5.9% NVIDIA win is modest by comparison, and the Radeon’s OpenCL score of 99048 still exceeds the RTX A4500 Mobile’s Vulkan score of 76960 by a wide margin.

The Verdict

The data supports a clear split verdict. For Vulkan-centric workloads — which often include modern cross-platform engines and Vulkan-native rendering pipelines — the AMD Radeon Pro Vega II is the definitive choice. Its 29.4% Vulkan advantage over the RTX A4500 Mobile is the largest margin in this entire comparison, and its average benchmark score of 109617 is over 20% higher than the NVIDIA card’s 91134. If raw aggregate performance is the primary criterion, the AMD card wins outright.

However, the RTX A4500 Mobile deserves consideration for OpenCL-heavy tasks. Its OpenCL score of 105307 beats the Radeon’s 99048 by 5.9%, and it achieves this while consuming only 140 W TDP versus the AMD card’s 475 W. The NVIDIA card also brings hardware features the AMD card lacks entirely — 46 RT cores and 184 tensor cores — which the Vulkan and OpenCL benchmarks do not directly measure. For users whose software stacks rely on OpenCL compute, the RTX A4500 Mobile is the safer pick despite its lower aggregate scores.

The percentile data suggests both cards are high-end, but the Radeon Pro Vega II’s 94th percentile versus the RTX A4500 Mobile’s 93rd indicates a slight overall edge for AMD. The average benchmark score difference — 109617 versus 91134 — is not marginal; it is a substantial gap that favors the AMD card across most workloads. The verdict is straightforward: pick the Radeon Pro Vega II for maximum compute throughput and Vulkan performance, pick the RTX A4500 Mobile for OpenCL efficiency and feature-rich acceleration.

Where Each One Wins

The AMD Radeon Pro Vega II wins decisively in Vulkan performance, posting a 99621 score that is 29.4% ahead of the RTX A4500 Mobile. It also wins on aggregate average benchmark score (109617 versus 91134) and sits higher in the percentile ranking (94th versus 93rd). Memory capacity is another clear win: 32 GB of HBM2 with a 4096-bit bus and 825.3 GB/s bandwidth versus the NVIDIA card’s 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s. The AMD card also offers higher texture rate (440.3 GTexel/s versus 276.0 GTexel/s) and higher FP32 throughput in its architecture (14.09 TFLOPS), though the NVIDIA card counters with a higher raw FP32 number (17.66 TFLOPS).

The NVIDIA RTX A4500 Mobile wins in OpenCL, scoring 105307 against 99048, a 5.9% margin. It also wins on pixel rate (144.0 GPixel/s versus 110.1 GPixel/s), shading units (5888 versus 4096), and ROPs (96 versus 64). The NVIDIA card’s TDP of 140 W is dramatically lower than the AMD’s 475 W, making it far more suitable for mobile or power-constrained deployments. It also has dedicated RT cores (46) and tensor cores (184), which the AMD card lacks entirely, and supports DirectX 12 Ultimate (12_2) versus the AMD’s DirectX 12 (12_1). For ray tracing or AI-accelerated tasks, the RTX A4500 Mobile is the only option with hardware support.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon Pro Vega II uses the Vega 20 chip built on GCN 5.1 architecture, fabricated on a 7 nm process at TSMC. It packs 13,230 million transistors into a 331 mm² die, yielding a transistor density of 40.0M per mm². The NVIDIA RTX A4500 Mobile uses the GA104 chip on Ampere architecture, built on an 8 nm Samsung process. It has 17,400 million transistors on a 392 mm² die, with a slightly higher density of 44.4M per mm². The AMD card’s smaller node gives it a power efficiency edge in theory, but its 475 W TDP suggests the architecture draws heavily under load.

Memory architecture diverges sharply. AMD uses 32 GB of HBM2 with a 4096-bit bus, achieving 825.3 GB/s bandwidth. NVIDIA uses 16 GB of GDDR6 with a 256-bit bus, delivering 512.0 GB/s. The AMD card’s bandwidth advantage is 61% higher, which directly impacts memory-bound workloads. Shader configurations also differ: the Radeon has 4096 shading units, 256 TMUs, and 64 ROPs, while the RTX A4500 Mobile has 5888 shading units, 184 TMUs, and 96 ROPs. NVIDIA’s higher shader count and ROP count are offset by fewer TMUs and lower clock speeds (930 MHz base, 1500 MHz boost versus 1574 MHz base, 1720 MHz boost).

Feature sets are where NVIDIA pulls ahead. The RTX A4500 Mobile has 46 RT cores and 184 tensor cores, enabling hardware ray tracing and AI acceleration. The AMD card has no such cores. NVIDIA also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while AMD supports DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The bus interface also differs: AMD uses Apple MPX, while NVIDIA uses PCIe 4.0 x16. Display outputs are similarly divergent — AMD offers 1x HDMI 2.0b and 4x Thunderbolt, while NVIDIA’s outputs are portable-device dependent.
