AMD Radeon PRO W7700 vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded data shows that the AMD Radeon PRO W7700 and the Intel Arc Pro B70 do not share any direct head-to-head benchmark entries in the database. The AMD card has two measured results: a Geekbench OpenCL score of 108245 and a Geekbench Vulkan score of 129706. The Intel Arc Pro B70 has no recorded benchmark scores at all, with an average benchmark score of 0 and a percentile rank of 50 among all GPUs. This absence of comparable measurements means the performance comparison must rely on the AMD card's established results and the architectural specifications of both cards.

The AMD Radeon PRO W7700 carries an average benchmark score of 118976, placing it in the 95th percentile of all GPUs in the database. Its nearest rivals provide context: the NVIDIA GB10 scores 117393, which is 1.3% behind the AMD card. The NVIDIA RTX 4000 SFF Ada Generation scores 117088, 1.6% behind. The NVIDIA Tesla V100 SXM2 16 GB scores 114395, 4% behind, and the NVIDIA RTX A5500 Mobile scores 113944, 4.4% behind. These deltas confirm that the Radeon PRO W7700 sits ahead of a cluster of high-end workstation GPUs in average benchmark performance.

The Intel Arc Pro B70 has no rivals listed and no scores to compare, so its performance tier cannot be established from measured results. The only quantitative signals are its raw specifications, which differ substantially from the AMD card. The Intel part delivers a higher pixel rate of 358.4 GPixel/s versus 249.6 GPixel/s for AMD, and a higher texture rate of 716.8 GTexel/s versus 499.2 GTexel/s. However, in FP32 compute, the AMD card leads with 31.95 TFLOPS against 22.94 TFLOPS for Intel, a gap of roughly 39% in AMD's favor. FP16 follows the same pattern: AMD delivers 63.90 TFLOPS versus 45.88 TFLOPS for Intel.

Memory bandwidth favors Intel at 608.0 GB/s versus 576.0 GB/s for AMD, a 5.6% advantage. The Intel card also doubles the memory capacity with 32 GB against 16 GB. Clock speeds favor Intel on both base and boost: 2280 MHz base and 2800 MHz boost versus 1900 MHz base and 2600 MHz boost for AMD. The AMD card compensates with a higher shading unit count per compute peak, but the Intel card has more shading units overall: 4096 versus 3072.

The Verdict

The recorded data supports a split verdict. For applications that depend on raw FP32 compute throughput, the AMD Radeon PRO W7700 is the stronger option, delivering 31.95 TFLOPS versus 22.94 TFLOPS for the Intel Arc Pro B70. Its measured average benchmark score of 118976 and 95th percentile ranking confirm that it performs at a high level among all GPUs in the database. The AMD card's nearest rivals all trail by margins between 1.3% and 4.4%, which places it in a competitive position against established workstation accelerators.

For workloads that prioritize memory capacity and rasterization throughput, the Intel Arc Pro B70 has the advantage. Its 32 GB of GDDR6 memory doubles the AMD card's 16 GB, which matters for large datasets and rendering scenes that exceed 16 GB. The Intel card also leads in pixel rate (358.4 GPixel/s versus 249.6 GPixel/s) and texture rate (716.8 GTexel/s versus 499.2 GTexel/s), indicating faster fill-rate-bound operations. Memory bandwidth is also higher on the Intel side at 608.0 GB/s versus 576.0 GB/s.

The AMD card uses a dual-slot cooler and requires a 450 W suggested power supply, while the Intel card also uses a dual-slot cooler but requires a 550 W suggested power supply. Both use a single 8-pin power connector. The AMD card is shorter at 241 mm (9.5 inches) versus 267 mm (10.5 inches) for Intel, and slightly taller at 111 mm (4.4 inches) versus 110 mm (4.3 inches). The Intel card is 39 mm (1.5 inches) wide, while the AMD card's width is not recorded.

Users who need maximum compute density per watt should note the AMD card's 190 W TDP against 230 W for Intel, despite the AMD card delivering higher FP32 throughput. The AMD card achieves this with a lower power requirement and a smaller physical footprint. The Intel card counters with more memory, higher fill rates, and faster clock speeds.

Where Each One Wins

The AMD Radeon PRO W7700 wins in compute-heavy workloads. Its FP32 output of 31.95 TFLOPS and FP16 output of 63.90 TFLOPS both exceed the Intel card's 22.94 TFLOPS and 45.88 TFLOPS respectively. The AMD card also has more ray tracing cores (48 versus 32), which can benefit rendering workloads that use ray-traced effects. Its measured average benchmark score of 118976 and 95th percentile ranking provide concrete evidence of strong overall performance, with nearest rivals trailing by 1.3% to 4.4%. The lower TDP of 190 W versus 230 W also makes it the more efficient choice for compute density.

The Intel Arc Pro B70 wins in memory-capacity-bound scenarios. Its 32 GB frame buffer is double the AMD card's 16 GB, which is decisive for datasets, textures, or render targets that exceed 16 GB. The Intel card also leads in pixel rate (358.4 GPixel/s versus 249.6 GPixel/s) and texture rate (716.8 GTexel/s versus 499.2 GTexel/s), making it the stronger option for fill-rate-limited rasterization. Memory bandwidth of 608.0 GB/s edges out the AMD card's 576.0 GB/s. The higher base clock of 2280 MHz and boost clock of 2800 MHz, versus 1900 MHz and 2600 MHz on AMD, may also help in latency-sensitive operations.

The bus interface gives Intel a potential platform advantage with PCIe 5.0 x16 versus PCIe 4.0 x16 on the AMD card, though the practical impact depends on the host system. The Intel card's display outputs include an HDMI 2.1a port alongside three DisplayPort 2.1 connections, while the AMD card offers four DisplayPort 2.1 outputs with no HDMI.
