AMD Radeon PRO W7600 vs Intel Arc A770 Comparison

Head-to-Head Benchmarks

The head-to-head data presents a clear, if somewhat lopsided, picture. In the two benchmark tests where both cards were measured, the Intel Arc A770 emerges victorious in both instances. The most significant divergence is found in the Geekbench OpenCL test, where the Intel Arc A770 scores 109175 compared to the AMD Radeon PRO W7600’s 81528. This represents a substantial 25.3% advantage for the Intel card, a deltaPct that underscores a major performance gulf in this particular compute-heavy workload. The AMD card is not just slightly behind; it is firmly outpaced in raw OpenCL throughput.

The second benchmark, Geekbench Vulkan, tells a much closer story. Here, the Intel Arc A770 scores 94284, while the AMD Radeon PRO W7600 trails with 92688. The deltaPct shrinks dramatically to just -1.7% for the AMD card. This indicates that while Intel holds the top spot, the performance difference in Vulkan is nearly negligible, falling within a margin that could be considered a statistical tie in real-world scenarios. The data suggests that AMD’s architecture is far more competitive in the Vulkan API than it is in OpenCL.

It is worth investigating what these raw scores imply. The OpenCL result is often associated with general-purpose GPU compute tasks, while Vulkan is a graphics and compute API. The 25.3% deficit for the AMD card in OpenCL is a stark contrast to its near-parity in Vulkan. This could point to driver maturity or architectural efficiency differences between the two brands under different API loads. The AMD card’s average benchmark score across its tested suite is 87108, while the Intel card’s average is 68809, a figure dragged down by its inclusion of a 3DMark Steel Nomad DX12 score of 2969, which is not present in the AMD data. This makes direct average-score comparisons misleading, but the head-to-head results are unambiguous.

The Verdict

The data supports a clear verdict for users prioritizing raw compute performance in OpenCL environments. The Intel Arc A770 is the definitive winner in the Geekbench OpenCL test, delivering a 25.3% higher score than the AMD Radeon PRO W7600. For any workload that leans heavily on this API, the Intel card is the data-backed choice. The Intel Arc A770 also holds a narrow lead in Vulkan, albeit by a slim 1.7% margin, meaning it is the more consistent performer across both tested APIs.

However, the AMD Radeon PRO W7600 is not without its merits. Its Vulkan score of 92688 is within striking distance of the Intel card's 94284, showing that it can hold its own in graphics-centric tasks. The choice then becomes about workload specificity. If a user’s primary applications are Vulkan-based, the AMD card offers near-identical performance to the Intel card, potentially making it a more suitable option based on other factors like power or size. But from a purely performance-per-benchmark standpoint, the Intel Arc A770 wins two out of two head-to-head matchups. The data does not show a single test where the AMD Radeon PRO W7600 comes out ahead, giving Intel the overall performance crown in this comparison.

For professionals running OpenCL-heavy compute tasks, the choice is obvious. The Intel Arc A770 offers a significant performance advantage. For those whose work is more balanced or geared toward Vulkan, the AMD card is competitive, but it still finishes second. The verdict is that the Intel Arc A770 is the faster card in this direct comparison, with the AMD card serving as a close alternative in Vulkan but a distant second in OpenCL.

Specification Differences

The two cards diverge significantly in their core specifications. The AMD Radeon PRO W7600 features 2048 shading units, 128 texture mapping units (TMUs), and 64 render output units (ROPs). In contrast, the Intel Arc A770 doubles these counts, offering 4096 shading units, 256 TMUs, and 128 ROPs. This doubling suggests a fundamentally different design philosophy, with Intel opting for a wider execution engine. The pixel rate and texture rate reflect this disparity: the AMD card outputs 156.2 GPixel/s and 312.3 GTexel/s, while the Intel card outputs 307.2 GPixel/s and 614.4 GTexel/s.

Memory configurations also differ markedly. The AMD card comes with 8 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 288.0 GB/s. The Intel card offers double the capacity at 16 GB of GDDR6, on a wider 256-bit bus, resulting in 512.0 GB/s of bandwidth. Clock speeds are similar, with the AMD card boosting to 2440 MHz and the Intel card boosting to 2400 MHz, but the base clocks differ, with Intel starting at 2100 MHz versus AMD’s 1720 MHz. Power requirements are also distinct, with the AMD card rated at 130 W TDP and a 300 W suggested PSU, while the Intel card is rated at 225 W TDP and a 550 W suggested PSU. The AMD card is a single-slot design with a 1x 6-pin power connector, while the Intel card is dual-slot and requires a 1x 6-pin plus 1x 8-pin connector. The bus interface differs, with AMD using PCIe 4.0 x8 and Intel using PCIe 4.0 x16. Display outputs vary, with AMD offering 4x DisplayPort 2.1 and Intel offering 1x HDMI 2.1 and 3x DisplayPort 2.0. The Intel card is larger, with dimensions not listed, but it is dual-slot. The AMD card is 241 mm long and 115 mm high. The Intel Arc A770 has a launch MSRP of 329 USD, while the AMD card has a launch MSRP of 599 USD.

Architecture Differences

The architectural foundations of these two GPUs are entirely different. The AMD Radeon PRO W7600 is built on the RDNA 3.0 architecture with the codename "Hotpink Bonefish," part of the Radeon Pro Navi (Navi III Series) generation. It uses the Navi 33 chip, fabricated on a 6 nm process at TSMC. The Intel Arc A770, by contrast, is based on the Xe-HPG architecture, part of the Alchemist (Arc 7) generation, and uses the DG2-512 chip, also fabricated on a 6 nm process at TSMC.

The physical characteristics of the chips differ substantially. The AMD chip contains 13,300 million transistors on a die size of 204 mm², resulting in a transistor density of 65.2M / mm². The Intel chip is much larger, with 21,700 million transistors on a 406 mm² die, yielding a lower transistor density of 53.4M / mm². This indicates that Intel has used more silicon to achieve its higher core counts.

Both cards feature 32 ray tracing cores, but the AMD card achieves this with 2048 shading units, while the Intel card does so with 4096 shading units. Neither card has tensor cores listed. The FP32 and FP16 performance figures are nearly identical, with the AMD card rated at 19.99 TFLOPS FP32 and 39.98 TFLOPS FP16 (2:1), and the Intel card rated at 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (2:1). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card has a production status of "Active" and a release date of 2023-08-02, while the Intel card is "End-of-life" with a release date of 2022-10-11. The Intel card's predecessor is Xe Graphics and its successor is Battlemage, while the AMD card's predecessor is Radeon Pro Vega.

Where Each One Wins

The benchmark data offers a specific map of where each card excels. The Intel Arc A770 claims the sole territory of OpenCL compute performance. Its 25.3% lead in Geekbench OpenCL is the single largest performance gap in the comparison. This makes it the clear choice for any application that is heavily optimized for OpenCL, where its higher shading unit count and memory bandwidth appear to pay significant dividends. The doubling of TMUs, ROPs, and memory bandwidth likely contributes to this dominant OpenCL showing.

The AMD Radeon PRO W7600, while not winning any head-to-head tests, shows its strength in the Vulkan API. Its score of 92688 is only 1.7% behind the Intel card, demonstrating that its architecture is highly efficient in this workload. This near-parity could make it a compelling option for Vulkan-based games or professional graphics applications that use this API, especially when considering its lower power draw of 130 W and single-slot form factor, which are advantages not reflected in the benchmark scores. The AMD card’s average benchmark score of 87108 is higher than the Intel card’s 68809, but this is due to the Intel card’s inclusion of the lower 3DMark score in its average. The data suggests that for users strictly looking at Vulkan performance, the AMD card is nearly as fast as the Intel card and offers a more power-efficient package.
