Intel Arc B770 vs NVIDIA RTX A1000 Comparison

Head-to-Head Benchmarks

The recorded data reveals a stark performance disparity between the Intel Arc B770 and the NVIDIA RTX A1000, with the Arc B770 holding dominant theoretical advantages across every major compute metric. The NVIDIA RTX A1000, however, comes with established benchmark scores from the database, while the Intel Arc B770 has no recorded benchmark submissions, leaving its real-world performance to be inferred from its architectural specifications.

The RTX A1000 delivers a 3DMark Steel Nomad DX12 score of 969, a Geekbench OpenCL score of 52,078, and a Geekbench Vulkan score of 49,574. These results place the card at the 79th percentile among all GPUs in the database, with an average benchmark score of 34,207. The Intel Arc B770 sits at the 50th percentile with an average benchmark score of zero due to the absence of logged tests, meaning the comparison must rely on raw specification differences.

On paper, the Arc B770 delivers 19.66 TFLOPS of FP32 compute, which is roughly three times the 6.737 TFLOPS of the RTX A1000. The pixel rate tells a similar story: 307.2 GPixel/s versus 46.78 GPixel/s, a factor of over 6.5 in favor of Intel. Texture rate follows the same pattern at 614.4 GTexel/s compared to 105.3 GTexel/s. The Arc B770 also carries 16 GB of GDDR6 memory on a 256-bit bus, yielding 512.0 GB/s of bandwidth, versus the RTX A1000's 8 GB on a 128-bit bus at 192.0 GB/s.

The RTX A1000's nearest rivals in the database include the NVIDIA RTX A2000 12 GB with an average score of 34,154 (0.2% higher), the AMD Radeon RX 560 XT at 34,133 (0.2% higher), the NVIDIA TITAN V at 34,355 (0.4% lower), and the AMD Radeon RX 480 at 33,997 (0.6% higher). These deltas are all within a single percentage point, indicating that the RTX A1000 sits in a tightly clustered performance band. The Arc B770, by contrast, has no nearest rivals listed, meaning its theoretical output places it in a different class altogether.

Where Each One Wins

The Intel Arc B770 wins decisively in raw throughput scenarios. Its 4096 shading units against 2304, 256 texture mapping units against 72, and 128 raster output units against 32 give it overwhelming advantages in fill-rate-bound workloads. The 512.0 GB/s memory bandwidth enables high-resolution texture streaming and large dataset handling that the RTX A1000's 192.0 GB/s cannot match. For FP32 compute tasks, the Arc B770's 19.66 TFLOPS nearly triples the RTX A1000's 6.737 TFLOPS, making it the clear choice for general compute acceleration.

The NVIDIA RTX A1000 wins in specific professional contexts. Its 72 tensor cores provide dedicated AI acceleration hardware, a feature the Arc B770 lacks entirely. The RTX A1000 also has 18 ray tracing cores, while the Arc B770 has 32, but the NVIDIA card's architecture is designed for workstation stability and certification. The RTX A1000 draws only 50 W from the slot, requires no auxiliary power connectors, and fits in a single-slot 163 mm length, making it suitable for dense multi-GPU workstation builds. The Arc B770 demands 225 W, a 1x 6-pin plus 1x 8-pin power setup, a 550 W suggested PSU, and a dual-slot footprint.

The RTX A1000 also wins on software ecosystem maturity, as its benchmark scores are recorded and its performance percentile is established at 79. The Arc B770's zero benchmark submissions mean no verified performance data exists in the database, only theoretical specifications. For users prioritizing proven results, the RTX A1000 holds the advantage.

The Verdict

The data indicates that the Intel Arc B770 is designed for maximum raw throughput. Its FP32 output of 19.66 TFLOPS, memory bandwidth of 512.0 GB/s, and shading unit count of 4096 place it in a different performance tier than the RTX A1000. Users processing large datasets, running high-resolution rendering, or executing compute-heavy FP32 workloads would find the Arc B770's specifications substantially more capable on paper.

The NVIDIA RTX A1000 serves a different purpose. Its 50 W power draw, slot-powered operation, and single-slot form factor make it suitable for multi-GPU workstation configurations where power density and physical space are constraints. The 72 tensor cores provide dedicated AI inference capability that the Arc B770 cannot offer. The RTX A1000 also has verified benchmark results: its Geekbench OpenCL score of 52,078 and Vulkan score of 49,574, along with its 79th percentile ranking, give it a proven performance profile.

The Arc B770's lack of recorded benchmarks means its actual performance remains unverified in the database. The RTX A1000's nearest rivals all fall within 0.6% of its average score, showing consistent, measurable performance. Users requiring immediate, documented results should favor the RTX A1000. Users prioritizing theoretical maximum compute throughput and memory capacity, and willing to accommodate a 225 W dual-slot card with external power, should consider the Arc B770 based on its specification sheet alone.
