AMD Radeon PRO W7700 vs Intel Arc A770 Comparison

The Verdict

The recorded data splits these two cards into clearly different roles. The AMD Radeon PRO W7700 is the workstation-oriented performer, commanding a 37.6% lead in Geekbench Vulkan over the Intel Arc A770. That single benchmark is a decisive margin, and it aligns with the W7700's higher average benchmark score of 118,976 versus the A770's 68,809. The W7700 also sits in the 95th percentile of all GPUs, while the A770 sits in the 90th.

The Intel Arc A770, however, is not without its own territory. It wins the Geekbench OpenCL test, scoring 109,175 against the W7700's 108,245, a narrow 0.9% edge. This is a tight race by any standard. For a builder prioritizing raw compute in OpenCL workloads, the A770 is the recorded choice. For Vulkan-centric applications, the W7700 is the clear pick.

The data also shows a stark contrast in board power and physical requirements. The W7700 is rated at 190 W with a suggested 450 W PSU, while the A770 draws 225 W and asks for a 550 W PSU. The W7700 achieves its higher Vulkan score with lower power draw. That is a meaningful efficiency signal. The A770 is also marked as end-of-life in the database, while the W7700 has no such status. For a long-term build, that favors the AMD card. The W7700 is the pick for Vulkan performance and efficiency; the A770 is the pick for OpenCL compute and a lower launch MSRP.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon PRO W7700 uses the Navi 32 chip based on RDNA 3.0 architecture, with the codename Wheat Nas. It is manufactured on a 5 nm process at TSMC, packing 28,100 million transistors into a 346 mm² die. The transistor density is 81.2M per mm².

The Intel Arc A770 uses the DG2-512 chip based on Xe-HPG architecture, from the Alchemist generation within the Arc 7 family. It is built on a 6 nm process, also at TSMC, with 21,700 million transistors on a larger 406 mm² die. Its transistor density is lower at 53.4M per mm². The A770's predecessor is Xe Graphics, and its successor is Battlemage, indicating a clear product lifecycle.

Core counts differ significantly. The A770 has 4,096 shading units, 256 TMUs, and 128 ROPs, while the W7700 has 3,072 shading units, 192 TMUs, and 96 ROPs. The A770 leads in raw shading and texture units. The W7700 has 48 RT cores; the A770 has 32. Neither card lists tensor cores. The W7700 has a higher base clock at 1900 MHz and a higher boost clock at 2600 MHz, while the A770 boosts to 2400 MHz from a 2100 MHz base.

Memory configurations are similar in capacity but not speed. Both use 16 GB of GDDR6 on a 256-bit bus. The W7700 runs memory at 2250 MHz with 18 Gbps effective speed, yielding 576.0 GB/s of bandwidth. The A770 runs at 2000 MHz with 16 Gbps effective, yielding 512.0 GB/s. The W7700 has 12.5% more bandwidth.

Head-to-Head Benchmarks

The head-to-head data contains two benchmark results, and each card wins one. The Geekbench OpenCL test is nearly a tie. The Intel Arc A770 scores 109,175, and the AMD Radeon PRO W7700 scores 108,245. The delta is a mere 0.9% in favor of Intel. This is within the margin of run-to-run variance, but the recorded winner is the A770. In practical terms, for OpenCL compute tasks, the two cards are effectively interchangeable.

The Geekbench Vulkan test is the decisive split. The W7700 scores 129,706, while the A770 scores 94,284. That is a 37.6% advantage for AMD. This is not a small gap; it is a commanding lead that will be visible in any Vulkan-based application. The W7700's higher FP32 throughput (31.95 TFLOPS versus 19.66 TFLOPS) and higher memory bandwidth (576.0 GB/s versus 512.0 GB/s) are consistent with this result.

The average benchmark scores in the database reinforce the picture. The W7700's average is 118,976, while the A770's is 68,809. This is a 72.9% difference in aggregate performance across all recorded workloads. The W7700's nearest rivals in the database are the NVIDIA GB10 (117,393, 1.3% behind), the NVIDIA RTX 4000 SFF Ada Generation (117,088, 1.6% behind), the NVIDIA Tesla V100 SXM2 16 GB (114,395, 4% behind), and the NVIDIA RTX A5500 Mobile (113,944, 4.4% behind). The A770's nearest rivals are the NVIDIA CMP 90HX (69,000, 0.3% ahead), the AMD Radeon Instinct MI25 (68,562, 0.4% behind), the AMD Radeon Pro WX 8200 (69,870, 1.5% behind), and the NVIDIA Quadro P6000 (69,986, 1.7% behind).

Where Each One Wins

The AMD Radeon PRO W7700 wins the Vulkan benchmark by a wide margin, and it does so while drawing less power. The data shows the W7700 at 190 W TDP versus the A770's 225 W TDP. The W7700 also has higher FP32 and FP16 compute rates, a higher boost clock, and more memory bandwidth. This makes it the stronger choice for Vulkan-based workloads, which include many modern games and compute APIs. Its 48 RT cores also exceed the A770's 32, which may matter in ray-traced scenarios. The W7700's 95th percentile ranking and higher average score indicate it sits in a higher performance class overall.

The Intel Arc A770 wins the OpenCL benchmark, and it wins on raw shading resources. The A770 has 4,096 shading units, 256 TMUs, and 128 ROPs, all higher than the W7700's counts. Its pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s are both higher. This suggests the A770 excels in tasks that are heavily rasterized and texture-bound, such as certain OpenCL compute kernels. The A770 also has a lower launch MSRP of 329 USD, which makes it an accessible entry point, though the database rules do not permit further price commentary.

The A770's end-of-life status in the database is a caution flag. The W7700 has no such status. For a new build in 2024 or later, the W7700 has a clear lifecycle advantage. The A770's predecessor is Xe Graphics, and its successor is Battlemage, which confirms that Intel has moved on. The W7700's predecessor is Radeon Pro Vega, and no successor is listed, meaning it is still a current product.

In summary, the data directs a Vulkan-centric builder toward the W7700, and an OpenCL-centric builder toward the A770, with the W7700 offering better efficiency and a longer product life.
