AMD Radeon Pro Vega II Duo vs Intel Arc A770 Comparison

Head-to-Head Benchmarks

The recorded database contains two direct head-to-head comparisons between the AMD Radeon Pro Vega II Duo and the Intel Arc A770, and the results split exactly one win apiece. This is not a one-sided contest; the two cards excel in different API environments, and the margin of victory is substantial in both directions.

In the Geekbench OpenCL test, the Intel Arc A770 posts a score of 109,175, which is 9.8% higher than the AMD Radeon Pro Vega II Duo’s 98,432. This is a decisive win for Intel, and it places the Arc A770 in a strong position for compute-heavy workloads that leverage OpenCL. The data shows that the Arc A770’s advantage here is not marginal; it is a clear, double-digit percentage gap that would be noticeable in any application that scales with raw OpenCL throughput.

The reverse is true in the Geekbench Vulkan test. The AMD Radeon Pro Vega II Duo scores 99,296, which is 5.3% ahead of the Intel Arc A770’s 94,284. While the margin is smaller than Intel’s OpenCL win, it is still a meaningful lead for AMD in this modern graphics API. Vulkan is increasingly important for game engines and professional visualization tools, so this win carries weight for users who prioritize that ecosystem.

Looking at the broader benchmark averages, the picture becomes more complex. The AMD Radeon Pro Vega II Duo has an average benchmark score of 106,750 across all recorded tests, which places it in the 94th percentile of all GPUs in the database. The Intel Arc A770, by contrast, has an average of 68,809, which is in the 90th percentile. The difference in raw averages is large, but it reflects a different set of test workloads, and the head-to-head results show that the Arc A770 can beat the Vega II Duo in specific scenarios.

The nearest rival data provides additional context. The AMD Radeon Pro Vega II Duo’s closest competitor is the AMD Radeon Pro W6600X, which scores 107,342 on average, meaning the Vega II Duo trails by only 0.6%. It also sits just 2.6% behind the AMD Radeon Pro Vega II and 3.6% behind the AMD Radeon PRO W7900. Against the NVIDIA Quadro RTX 6000, the Vega II Duo leads by 4.8%. These comparisons show that the Vega II Duo is tightly clustered with other high-end professional cards, and its performance is consistent with that tier.

For the Intel Arc A770, the nearest rivals are a different group. The NVIDIA CMP 90HX scores 69,000 on average, which is 0.3% lower than the Arc A770’s 68,809. The AMD Radeon Instinct MI25 scores 68,562, which is 0.4% lower. The AMD Radeon Pro WX 8200 and NVIDIA Quadro P6000 score 69,870 and 69,986 respectively, putting the Arc A770 1.5% and 1.7% behind them. This indicates that the Arc A770 is positioned in a slightly lower performance tier than the Vega II Duo when considering aggregate scores, but it is competitive within its own class.

The Verdict

The data suggests that the choice between these two cards depends heavily on the target workload and API. For users who rely on OpenCL, the Intel Arc A770 is the stronger pick. Its 9.8% lead over the Vega II Duo in that specific test is the largest single margin in the head-to-head results, and it is backed by a higher FP32 throughput of 19.66 TFLOPS compared to the AMD card’s 14.09 TFLOPS. The Arc A770 also has a higher boost clock of 2400 MHz versus 1720 MHz, and it draws less power at 225 W versus 475 W. For compute tasks that are OpenCL-bound, the Arc A770 is the data-backed winner.

For users who prioritize Vulkan performance, the AMD Radeon Pro Vega II Duo is the better option. Its 5.3% lead in the Vulkan test, combined with a 94th percentile ranking versus the Arc A770’s 90th, shows that the Vega II Duo holds its own in modern graphics APIs. The Vega II Duo also offers significantly more memory: 32 GB of HBM2 with a 4096-bit bus and 1.02 TB/s bandwidth, compared to the Arc A770’s 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s. For large datasets or high-resolution textures, the Vega II Duo’s memory subsystem is a clear advantage.

The production status of both cards is end-of-life, so neither is a future-proof purchase. However, the data shows that the Vega II Duo is aimed at a professional, high-end market with its Apple MPX bus interface and quad-slot cooler, while the Arc A770 is a more conventional dual-slot PCIe 4.0 x16 card. The Vega II Duo’s average benchmark score of 106,750 is 55.1% higher than the Arc A770’s 68,809, which suggests that in aggregate, the AMD card is the more powerful overall. But the head-to-head results remind us that aggregate scores do not tell the whole story.

In short: pick the Intel Arc A770 for OpenCL-heavy workloads and lower power draw. Pick the AMD Radeon Pro Vega II Duo for Vulkan performance, massive memory capacity, and higher overall benchmark scores.

Specification Differences

The two cards differ in nearly every major specification category. The AMD Radeon Pro Vega II Duo uses a Vega 20 chip on a 7 nm process from TSMC, while the Intel Arc A770 uses a DG2-512 chip on a 6 nm process, also from TSMC. The Vega II Duo has 13,230 million transistors on a 331 mm² die, while the Arc A770 has 21,700 million transistors on a 406 mm² die. The transistor density is 40.0M per mm² for AMD and 53.4M per mm² for Intel.

Clock speeds differ significantly. The AMD card has a base clock of 1400 MHz and a boost clock of 1720 MHz, while the Intel card has a base clock of 2100 MHz and a boost clock of 2400 MHz. Memory clocks also differ: the Vega II Duo runs at 1000 MHz with 2 Gbps effective, while the Arc A770 runs at 2000 MHz with 16 Gbps effective.

Both cards have 4096 shading units and 256 TMUs, but the ROP count differs: 64 for AMD and 128 for Intel. The Intel Arc A770 has 32 ray tracing cores, while the AMD Radeon Pro Vega II Duo has none listed. Pixel rate and texture rate favor Intel: 307.2 GPixel/s and 614.4 GTexel/s versus 110.1 GPixel/s and 440.3 GTexel/s for AMD. FP32 compute is 14.09 TFLOPS for AMD and 19.66 TFLOPS for Intel. FP16 is 28.18 TFLOPS and 39.32 TFLOPS respectively.

The power profile is starkly different. The AMD card has a TDP of 475 W and a suggested PSU of 850 W, while the Intel card has a TDP of 225 W and a suggested PSU of 550 W. The AMD card is quad-slot with an Apple MPX bus interface, while the Intel card is dual-slot with a PCIe 4.0 x16 interface. Display outputs are 1x HDMI 2.0b and 4x Thunderbolt for AMD, versus 1x HDMI 2.1 and 3x DisplayPort 2.0 for Intel.

Architecture Differences

The architectural divide is fundamental. The AMD Radeon Pro Vega II Duo is built on GCN 5.1 architecture, a mature design from the Vega era, while the Intel Arc A770 uses Xe-HPG architecture from the Alchemist generation. The AMD card belongs to the Radeon Pro Mac (Vega Series) generation, while the Intel card is part of the Alchemist (Arc 7) generation.

The memory architecture is completely different. AMD uses 32 GB of HBM2 with a 4096-bit bus, achieving 1.02 TB/s bandwidth. Intel uses 16 GB of GDDR6 with a 256-bit bus, achieving 512.0 GB/s bandwidth. This means the AMD card has twice the memory capacity and double the memory bandwidth, a major advantage for memory-bound workloads.

The Intel card introduces ray tracing hardware with 32 dedicated RT cores, a feature entirely absent from the AMD card. This makes the Arc A770 better suited for ray-traced rendering workloads, assuming software support is present. The AMD card relies on traditional rasterization and compute performance.

API support differs as well. The AMD card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The Intel card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The higher DirectX version and Vulkan 1.4 support give Intel a slight edge in modern API compatibility.

Release dates are separated by over three years: the AMD card launched on June 2, 2019, and the Intel card launched on October 11, 2022. The Intel card has a listed predecessor (Xe Graphics) and successor (Battlemage), while the AMD card has neither. Both cards are marked as end-of-life in the database, and both are manufactured by TSMC, though on different process nodes.
