AMD Radeon PRO W7700 vs Intel Arc B770 Comparison

Where Each One Wins

The recorded data presents an unusual comparison because the two cards occupy very different positions in the database. The AMD Radeon PRO W7700 has two completed benchmark entries, while the Intel Arc B770 has no recorded benchmark scores at all. The AMD card sits at the 95th percentile among all GPUs in the database, while the Intel part is listed at the 50th percentile with an average benchmark score of zero.

The AMD Radeon PRO W7700 delivers its strongest result in the Geekbench Vulkan test with a score of 129706, which is higher than its Geekbench OpenCL result of 108245. The Intel Arc B770 has no benchmark wins to claim because no test results exist for it in the database.

When the database calculates the average benchmark score, the AMD card produces 118976 points. The Intel card produces zero points because its benchmark array is empty. The nearest rival data also only exists for the AMD card, which shows it competing closely with several NVIDIA workstation and mobile parts.

The AMD card wins the OpenCL and Vulkan categories by default, since the Intel card has no data in either test. The Intel card cannot be credited with any wins in any category based on available measurements.

Architecture Differences

The two cards come from different manufacturers and use different GPU architectures. The AMD Radeon PRO W7700 uses the Navi 32 chip built on RDNA 3.0 architecture with the codename Wheat Nas. Its generation is listed as Radeon Pro Navi, specifically the Navi III Series. The Intel Arc B770 uses the BMG-G31 chip built on Xe2-HPG architecture and belongs to the Battlemage generation, specifically the Arc 7 series.

Both cards are fabricated by TSMC on a 5 nm process node. The AMD card contains 28,100 million transistors on a die size of 346 mm², which produces a transistor density of 81.2 million transistors per square millimeter. The Intel card has an unknown transistor count but a larger die size of 368 mm², and its transistor density is not recorded.

The clock behavior differs between the two. The AMD card has a base clock of 1900 MHz and a boost clock of 2600 MHz. The Intel card has a higher base clock of 2100 MHz but a lower boost clock of 2400 MHz. Memory clocks also differ: the AMD card runs its memory at 2250 MHz with 18 Gbps effective speed, while the Intel card runs at 2000 MHz with 16 Gbps effective speed.

The compute unit layouts are substantially different. The AMD card has 3072 shading units, 192 texture mapping units, and 96 render output units. The Intel card has 4096 shading units, 256 texture mapping units, and 128 render output units. The AMD card has 48 ray tracing cores, while the Intel card has 32 ray tracing cores. Neither card lists tensor cores.

The memory subsystems share the same size and bus width: both have 16 GB of GDDR6 memory on a 256 bit bus. The bandwidth differs because of the memory clock difference, with the AMD card reaching 576.0 GB/s and the Intel card reaching 512.0 GB/s.

Power requirements differ. The AMD card has a TDP of 190 W, uses a single 8-pin power connector, and the suggested power supply is 450 W. The Intel card has a TDP of 225 W, uses one 6-pin plus one 8-pin power connector, and the suggested power supply is 550 W.

Display outputs also differ. The AMD card provides 4x DisplayPort 2.1 outputs. The Intel card provides 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs. Both cards use a PCIe 4.0 x16 bus interface and are dual-slot designs.

The API support is identical for both cards: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The AMD card has a recorded release date of November 12, 2023, while the Intel card has a release date of December 31, 2025. The AMD card lists Radeon Pro Vega as its predecessor, and the Intel card lists Alchemist as its predecessor. Neither card has a recorded successor.

Head-to-Head Benchmarks

The head-to-head benchmark array between the two cards is empty, meaning no direct comparative test results exist in the database. The only benchmark data available belongs to the AMD Radeon PRO W7700.

In Geekbench OpenCL, the AMD card scores 108245 points. In Geekbench Vulkan, it scores 129706 points. These results place the AMD card at the 95th percentile among all GPUs.

The nearest rival comparisons for the AMD card provide context for its performance level. The NVIDIA GB10 has an average score of 117393, which is 1.3 percent lower than the AMD card. The NVIDIA RTX 4000 SFF Ada Generation has an average score of 117088, which is 1.6 percent lower. The NVIDIA Tesla V100 SXM2 16 GB has an average score of 114395, which is 4 percent lower. The NVIDIA RTX A5500 Mobile has an average score of 113944, which is 4.4 percent lower.

The average benchmark score for the AMD card is 118976, which sits between its two individual test results. The OpenCL result pulls the average down from the Vulkan result, indicating the card performs better under the Vulkan API in the recorded measurements.

The Intel Arc B770 has no benchmark entries, no average score, and no nearest rivals in the database. Its percentile rank of 50 is a default placement rather than a measured result, since the average benchmark score of zero cannot support any comparative analysis.

Because the head-to-head array is empty, no direct win margins can be calculated between the two cards. The only statement the data supports is that the AMD card has measurable performance in two APIs, while the Intel card has no recorded measurements.

The Verdict

The database contains complete performance data for the AMD Radeon PRO W7700 and no performance data for the Intel Arc B770. This asymmetry means any selection between the two cards must rely on what the recorded measurements show.

For users who require verified benchmark results, the AMD Radeon PRO W7700 is the only card with data. Its Geekbench Vulkan score of 129706 and Geekbench OpenCL score of 108245 place it at the 95th percentile among all GPUs. Its average benchmark score of 118976 puts it slightly ahead of several NVIDIA parts, with the closest rival being the NVIDIA GB10 at 1.3 percent lower.

The Intel Arc B770 offers a larger compute configuration on paper, with 4096 shading units compared to 3072 for the AMD card, and a higher base clock of 2100 MHz. However, the database contains no measurements that confirm how this hardware translates into actual performance. The card is listed at the 50th percentile, which is a neutral placement given the absence of scores.

The AMD card also leads in memory bandwidth with 576.0 GB/s versus 512.0 GB/s for the Intel card, and it has a lower TDP of 190 W versus 225 W. The AMD card requires a 450 W power supply while the Intel card requires a 550 W power supply.

The Intel card has a later release date of December 31, 2025, compared to November 12, 2023 for the AMD card. The Intel card also has no launch MSRP recorded, while the AMD card has a launch MSRP of 999 USD.

The data supports choosing the AMD Radeon PRO W7700 when verified performance is required. The data does not support choosing the Intel Arc B770 on the basis of benchmark results, because none exist. The Intel card can only be evaluated on its hardware specifications, which show a higher shading unit count, higher texture and pixel rates, and a larger die.

Users who prioritize measured performance should note that the AMD card delivers 31.95 TFLOPS of FP32 compute and 63.90 TFLOPS of FP16 compute. The Intel card delivers 19.66 TFLOPS of FP32 and 39.32 TFLOPS of FP16. The AMD card leads in every compute throughput category recorded in the database.
