AMD Radeon Vega Frontier Edition vs Intel Arc A770 Comparison

The AMD Radeon Vega Frontier Edition and Intel Arc A770 represent two distinct eras of GPU design, separated by five years of architectural evolution. The data shows a clear performance hierarchy in the available benchmarks, with the Intel Arc A770 securing a decisive victory in both head-to-head compute tests. However, the comparison extends beyond raw scores, revealing significant differences in architecture, feature support, and system requirements that define each card’s intended use case. The Vega Frontier Edition, launched in 2017, was AMD’s initial foray into dedicated compute-oriented graphics, while the Arc A770, released in 2022, is Intel’s ambitious entry into the discrete GPU market. Their average benchmark scores—73,370 for the AMD card and 68,809 for the Intel card—place them within striking distance of each other, yet the specific test results tell a more nuanced story about workload suitability.

Head-to-Head Benchmarks

The direct comparison between these two cards is limited to two compute-oriented tests: Geekbench OpenCL and Geekbench Vulkan. In both instances, the Intel Arc A770 emerges as the clear winner, though the margin varies significantly between the API tests. In Geekbench OpenCL, the Arc A770 scores 109,175 against the Vega Frontier Edition’s 76,111, representing a 30.3% advantage for Intel. This is a substantial lead, indicating that the newer architecture handles general-purpose compute tasks with considerably greater efficiency. The Vulkan test shows a narrower but still decisive gap: the Arc A770 posts 94,284 versus 71,937 for the AMD card, a 23.7% margin. These results are consistent with the architectural generational leap, as the Arc A770’s Xe-HPG design is optimized for modern graphics APIs and parallel workloads.

The deltaPct values in the head-to-head data are negative for the AMD card, confirming its inferior position in both tests. Notably, the OpenCL gap is larger than the Vulkan gap, suggesting that Intel’s driver stack and hardware scheduling are particularly well-suited to OpenCL’s execution model. For the Vega Frontier Edition, these results highlight its age; despite having the same 4,096 shading units as the Arc A770, the older GCN 5.0 architecture cannot match the per-clock efficiency of Intel’s newer design. The benchmark data shows no wins for the AMD card in any direct comparison, with a 0-2 record in the head-to-head tests. This asymmetry is important context for buyers prioritizing compute performance, as the Arc A770 delivers a consistently faster experience across both major cross-platform APIs.

Where Each One Wins

The performance landscape shifts when examining the broader benchmark suite and system-level characteristics. The AMD Radeon Vega Frontier Edition holds a slight edge in average benchmark score, posting 73,370 compared to the Intel Arc A770’s 68,809, a difference of roughly 6.6%. This is notable because the average includes a wider range of tests beyond the two head-to-head comparisons, suggesting that the Vega card may have strengths in workloads not captured by the OpenCL and Vulkan tests. The Vega Frontier Edition also ranks at the 91st percentile among all GPUs, one point higher than the Arc A770’s 90th percentile, indicating that its overall performance profile is marginally more competitive relative to the broader market.

For the Intel Arc A770, its wins are concentrated in the modern compute benchmarks, where its 30.3% and 23.7% leads in OpenCL and Vulkan, respectively, are decisive. Additionally, the Arc A770’s feature set gives it advantages in specific use cases. It supports DirectX 12 Ultimate (12_2), whereas the Vega Frontier Edition only reaches DirectX 12 (12_1), meaning the Intel card is better positioned for games and applications that leverage ray tracing and mesh shaders through the latest API features. The Arc A770 also includes 32 dedicated ray tracing cores, a feature entirely absent from the AMD card, which lacks any RT cores. For Vulkan support, the Intel card is ahead with version 1.4, while the AMD card offers 1.3. These API and feature differences suggest the Arc A770 is the stronger choice for contemporary gaming and ray-traced workloads, while the Vega Frontier Edition’s higher average score may reflect better optimization in legacy or compute-specific scenarios not covered by the head-to-head tests.

Architecture Differences

The architectural divide between these two cards is profound, reflecting the five-year gap in their release dates. The AMD Radeon Vega Frontier Edition is built on the GCN 5.0 architecture using a 14 nm process from GlobalFoundries, with a die size of 495 mm² housing 12,500 million transistors. In contrast, the Intel Arc A770 uses the Xe-HPG architecture on TSMC’s 6 nm node, packing 21,700 million transistors into a smaller 406 mm² die. This results in a transistor density of 53.4 million per mm² for Intel, more than double the AMD card’s 25.3 million per mm², showcasing the density improvements from the newer process technology.

Memory configurations differ substantially as well. The Vega Frontier Edition uses 16 GB of HBM2 on a 2048-bit bus, delivering 483.8 GB/s of bandwidth, while the Arc A770 uses 16 GB of GDDR6 on a 256-bit bus, achieving slightly higher bandwidth at 512.0 GB/s. The AMD card’s memory runs at 945 MHz (1,890 Mbps effective), whereas the Intel card’s memory operates at 2,000 MHz (16 Gbps effective). Core configurations show both cards have 4,096 shading units and 256 texture mapping units, but the ROP count differs: the Vega card has 64, while the Arc A770 has 128, doubling the pixel throughput. This is reflected in their pixel rates—102.4 GPixel/s for AMD versus 307.2 GPixel/s for Intel—and texture rates of 409.6 GTexel/s versus 614.4 GTexel/s, respectively. The clock speeds also favor Intel, with a base of 2,100 MHz and boost of 2,400 MHz, compared to AMD’s 1,382 MHz base and 1,600 MHz boost. These differences culminate in FP32 performance of 19.66 TFLOPS for Intel versus 13.11 TFLOPS for AMD, and FP16 of 39.32 TFLOPS versus 26.21 TFLOPS, both at a 2:1 ratio.

Power and system requirements also differ significantly. The Vega Frontier Edition has a 300 W TDP and requires a 700 W power supply with two 8-pin connectors, while the Arc A770 is more efficient at 225 W TDP, needing a 550 W PSU and a single 6-pin plus one 8-pin connector. The Intel card also uses PCIe 4.0 x16, doubling the bandwidth of the AMD card’s PCIe 3.0 x16 interface. Display outputs favor Intel with DisplayPort 2.0 support versus DisplayPort 1.4a on the AMD card, though both offer HDMI (2.1 for Intel, 2.0b for AMD). The AMD card is a dual-slot design measuring 267 mm in length and 111 mm in height, while the Intel card’s dimensions are not listed.

The Verdict

Based strictly on the benchmark data, the Intel Arc A770 is the superior choice for users prioritizing modern compute performance. Its 30.3% lead in OpenCL and 23.7% lead in Vulkan over the AMD Radeon Vega Frontier Edition are substantial margins that cannot be ignored, particularly for developers or professionals running cross-platform compute workloads. The Arc A770 also offers a more advanced feature set, including ray tracing cores, DirectX 12 Ultimate support, and higher Vulkan version, making it better suited for future-proofing. Its lower TDP of 225 W versus 300 W, combined with a smaller power supply requirement, adds to its practical appeal.

However, the AMD Radeon Vega Frontier Edition remains competitive in specific scenarios. Its higher average benchmark score of 73,370 and 91st percentile ranking indicate that it holds its own in a broader range of tests beyond the head-to-head comparisons. For users working with legacy applications optimized for GCN architecture, or those who require the unique HBM2 memory configuration, the Vega card remains a viable option. Its 16 GB of memory matches the Arc A770, though with lower bandwidth. The AMD card’s larger die size and older process node contribute to higher power consumption, but its end-of-life status and 2017 release date mean it may be available at lower prices in the secondary market.

For most users, the Intel Arc A770 is the recommended choice due to its decisive compute wins and modern feature set. The data shows a clear generational improvement in performance per watt and raw throughput. The Vega Frontier Edition, meanwhile, is best suited for niche applications where its specific architecture or higher average score provides an advantage, or for those with legacy software dependencies. Ultimately, the benchmarks favor Intel by a wide margin in the tested workloads, making the Arc A770 the more capable and future-ready graphics card.
