Intel Arc B770 vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark scores for the Intel Arc B770 and the NVIDIA B300 SXM6 AC. The Arc B770 has no recorded benchmark entries, while the B300 SXM6 AC has a single Geekbench OpenCL result. No direct head-to-head comparison is possible from the recorded data. The B300 SXM6 AC scores 369,831 points in Geekbench OpenCL, placing it in the 100th percentile of all GPUs. Its nearest rivals trail by significant margins: the NVIDIA B200 scores 345,482 (7% behind), the H200 NVL scores 334,891 (10.4% behind), the AMD Instinct MI300X scores 317,994 (16.3% behind), and the L40S scores 295,763 (25% behind). The Arc B770, by contrast, sits in the 50th percentile with an average benchmark score of zero, indicating no comparable workload results exist in the database.

The B300 SXM6 AC is a dominant performer in compute workloads, as its OpenCL score suggests. The 7% lead over the B200 and the 25% margin over the L40S place it firmly at the top of the database's GPU rankings. The Arc B770 cannot be measured against this score because no data exists; its percentile ranking of 50 reflects an absence of recorded benchmarks rather than a measured performance level.

Where Each One Wins

The B300 SXM6 AC wins decisively in compute throughput. Its FP32 performance is 76.99 TFLOPS, and its FP16 performance matches at 76.99 TFLOPS (1:1 ratio). The Arc B770 delivers 19.66 TFLOPS FP32 and 39.32 TFLOPS FP16 (2:1 ratio). In raw compute, the B300 SXM6 AC is roughly 3.9 times faster in FP32 and roughly 2 times faster in FP16. The B300 SXM6 AC also has a massive memory advantage: 288 GB of HBM3e on a 8192-bit bus delivers 8.19 TB/s bandwidth, compared to the Arc B770's 16 GB of GDDR6 on a 256-bit bus at 512.0 GB/s. That is a 16-fold capacity difference and a 16-fold bandwidth difference.

The Arc B770 wins in graphics-oriented features. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B300 SXM6 AC lists N/A for all three APIs. The Arc B770 has display outputs: 1x HDMI 2.1a and 3x DisplayPort 2.1. The B300 SXM6 AC has no outputs. The Arc B770 also has a higher pixel rate at 307.2 GPixel/s versus 48.77 GPixel/s for the B300 SXM6 AC, and a higher ROP count at 128 versus 24.

The Verdict

The data confirms these are two entirely different classes of hardware. The NVIDIA B300 SXM6 AC is a server-grade compute accelerator with no display output, no graphics API support, and an 1100 W power envelope. Its 76.99 TFLOPS FP32, 288 GB HBM3e, and 592 tensor cores position it for AI training, scientific simulation, and data center workloads. Its OpenCL score of 369,831 places it in the 100th percentile, with a 7% lead over the B200 and a 25% lead over the L40S.

The Intel Arc B770 is a consumer graphics card with 16 GB GDDR6, display outputs, full DirectX 12 Ultimate support, and 32 RT cores. Its 225 W TDP and PCIe 4.0 interface make it suitable for conventional desktop gaming and workstation graphics tasks. It has no tensor cores and its FP16 performance uses a 2:1 ratio, indicating it is not optimized for AI compute.

The B300 SXM6 AC's pixel rate of 48.77 GPixel/s is far lower than the Arc B770's 307.2 GPixel/s, and its 24 ROPs suggest it is not designed for rasterization. The Arc B770's texture rate of 614.4 GTexel/s is roughly half the B300 SXM6 AC's 1,202.9 GTexel/s, but the B300 SXM6 AC's advantage comes from raw shader count, not graphics features.

For users building a gaming PC or a workstation with display output, the Arc B770 is the only viable choice from this data. For users running compute workloads that benefit from massive memory capacity, tensor cores, and extreme FP32 throughput, the B300 SXM6 AC is the clear selection. The B300 SXM6 AC has a production status of Active, while the Arc B770 does not list one. The B300 SXM6 AC also has a defined successor in Server Rubin, while the Arc B770 has none listed.

The benchmark data shows no overlap in intended use. The Arc B770 sits in the 50th percentile with no recorded scores, which means its performance cannot be quantified relative to other GPUs. The B300 SXM6 AC sits in the 100th percentile, outperforming its nearest recorded rivals by margins from 7% to 25%. The choice depends entirely on workload: graphics rendering and display output point to the Arc B770, while compute density and AI acceleration point to the B300 SXM6 AC.
