AMD Radeon Vega Frontier Edition vs NVIDIA GeForce RTX 4080 Comparison

The Verdict

The recorded data presents a decisive outcome: the NVIDIA GeForce RTX 4080 wins both head-to-head benchmark comparisons against the AMD Radeon Vega Frontier Edition. In the two shared tests, Geekbench OpenCL and Geekbench Vulkan, the RTX 4080 leads by margins of 64.6% and 72.7%, respectively. These are not narrow victories; they represent a generational leap in raw compute performance. The AMD Vega Frontier Edition, an end-of-life product from 2017, cannot compete with the RTX 4080 on raw throughput. The data suggests the RTX 4080 is the clear choice for anyone prioritizing maximum benchmark scores and modern API support. The Vega Frontier Edition, while still holding a 91st percentile ranking among all GPUs, is simply outclassed by the RTX 4080's 86th percentile ranking when considering the absolute score disparity. For users requiring the highest possible OpenCL or Vulkan performance, the RTX 4080 is the only rational selection based on these measurements. The Vega card retains relevance only for legacy workflows or specific compute tasks where its older architecture and HBM2 memory might be a requirement, but the benchmark data does not support a performance-based argument for its selection.

Where Each One Wins

The head-to-head data shows the NVIDIA GeForce RTX 4080 winning every shared benchmark. In Geekbench OpenCL, the RTX 4080 scores 214,739 against the Vega Frontier Edition's 76,111, a delta of 64.6%. This is a massive advantage in general-purpose compute workloads that leverage OpenCL. In Geekbench Vulkan, the RTX 4080 scores 263,779 against 71,937, a delta of 72.7%. This indicates the RTX 4080 has a particularly strong advantage in Vulkan-based graphics and compute tasks. The AMD Vega Frontier Edition has no benchmark wins in the recorded data. Its own individual benchmarks show Geekbench Metal at 72,061, Geekbench OpenCL at 76,111, and Geekbench Vulkan at 71,937, with an average benchmark score of 73,370. These are respectable figures for a GPU of its era, but they are far below the RTX 4080's scores. The RTX 4080's average benchmark score across all its tests is 54,247, which is lower than the Vega card's average due to the inclusion of low-scoring Passmark DirectX tests (e.g., Passmark DirectX 9 at 370, Passmark DirectX 12 at 132). However, in the two directly comparable modern API tests, the RTX 4080 dominates. The data indicates the RTX 4080 is the winner for any application using OpenCL or Vulkan. The Vega Frontier Edition does not show a competitive advantage in any measured category.

Architecture Differences

The two GPUs come from different eras and architectures. The AMD Radeon Vega Frontier Edition uses the Vega 10 chip on a 14 nm process from GlobalFoundries. It packs 12,500 million transistors on a 495 mm² die, with a transistor density of 25.3 million per mm². The NVIDIA GeForce RTX 4080 uses the AD103 chip on a 5 nm process from TSMC. It contains 45,900 million transistors on a 379 mm² die, resulting in a transistor density of 121.1 million per mm². This density difference is a key factor in the performance gap. The Vega card's architecture is GCN 5.0, while the RTX 4080 uses Ada Lovelace. The Vega card has 4,096 shading units, 256 TMUs, and 64 ROPs. The RTX 4080 has significantly more: 9,728 shading units, 304 TMUs, and 112 ROPs. The RTX 4080 also includes 76 RT cores and 304 tensor cores, which the Vega card lacks entirely. Clock speeds differ substantially. The Vega Frontier Edition has a base clock of 1382 MHz and a boost clock of 1600 MHz. The RTX 4080 has a base clock of 2205 MHz and a boost clock of 2505 MHz. Memory configurations are both 16 GB, but the type and bandwidth differ. The Vega card uses HBM2 with a 2048-bit bus and 483.8 GB/s bandwidth. The RTX 4080 uses GDDR6X with a 256-bit bus and 716.8 GB/s bandwidth. The RTX 4080 has higher peak theoretical rates: 280.6 GPixel/s pixel rate, 761.5 GTexel/s texture rate, and 48.74 TFLOPS FP32. The Vega card has 102.4 GPixel/s, 409.6 GTexel/s, and 13.11 TFLOPS FP32. The RTX 4080 also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Vega card supports DirectX 12 (12_1) and Vulkan 1.3. The RTX 4080 uses PCIe 4.0 x16, whereas the Vega card uses PCIe 3.0 x16. These architectural differences, particularly the newer process node, higher transistor count, and inclusion of dedicated RT and tensor cores, explain the RTX 4080's benchmark superiority.

Head-to-Head Benchmarks

The head-to-head benchmark data is limited to two tests, but both are decisive. The first test, Geekbench OpenCL, shows the NVIDIA GeForce RTX 4080 scoring 214,739 against the AMD Radeon Vega Frontier Edition's 76,111. The delta is 64.6% in favor of the RTX 4080. This is a substantial margin that reflects the RTX 4080's superior compute throughput in OpenCL workloads. The Vega card's score of 76,111 is consistent with its standalone Geekbench OpenCL result, confirming the data's reliability. The RTX 4080's advantage here is more than double, indicating that for OpenCL-accelerated applications, the RTX 4080 is the superior choice by a wide margin. The second test, Geekbench Vulkan, shows an even larger gap. The RTX 4080 scores 263,779, while the Vega Frontier Edition scores 71,937. The delta is 72.7% in favor of the RTX 4080. This is the biggest win for either card in the head-to-head comparison. Vulkan is a modern, low-overhead API, and the RTX 4080's architecture is clearly better optimized for it. The Vega card, with its older GCN 5.0 architecture, lags significantly. The data shows the RTX 4080 wins 2 out of 2 head-to-head benchmarks, with no wins recorded for the Vega Frontier Edition. The average benchmark scores from the broader database also provide context. The Vega Frontier Edition's nearest rivals include the AMD Radeon Pro Vega 64 (1.4% higher average score), NVIDIA TITAN X Pascal (1.8% lower), AMD Radeon RX 6650M (2.2% lower), and AMD Radeon RX 6600 LE (3.6% lower). This places the Vega card in a specific performance tier. The RTX 4080's nearest rivals are the NVIDIA GeForce RTX 4080 SUPER (0.1% higher), AMD Radeon Pro W5700X (1.1% higher), AMD Radeon RX 6750 GRE 12 GB (2.6% higher), and AMD Radeon 8060S (2.7% higher). This shows the RTX 4080 sits in a much higher performance tier, despite its lower average score from the mixed test suite. The head-to-head results, however, are unambiguous: the RTX 4080 is the clear winner in both OpenCL and Vulkan, with margins of 64.6% and 72.7%, respectively. These numbers indicate a generational performance gap that cannot be overcome by the Vega card's older architecture.
