Head-to-Head Benchmarks

The recorded database contains no benchmark scores for either GPU, and no head-to-head benchmark entries exist. Both products show an average benchmark score of 0 and a percentile versus all GPUs of 50. With no measured results, the comparison relies on the specification-level metrics provided in the database.

The FP32 compute gap is the most striking difference. The B200 SXM6 delivers 69.34 TFLOPS, which is 5.64 times the 12.29 TFLOPS of the Arc Pro B65. In FP16, the B200 SXM6 again produces 69.34 TFLOPS at a 1:1 ratio, while the Arc Pro B65 reaches 24.58 TFLOPS at a 2:1 ratio. The B200 SXM6 leads by 2.82 times in FP16 throughput.

Memory bandwidth shows an even larger disparity. The B200 SXM6 provides 8.19 TB/s, which is 13.47 times the 608.0 GB/s of the Arc Pro B65. This bandwidth advantage is critical for workloads that stream large datasets, such as AI training or scientific simulation.

Pixel rate is the one rasterization metric where the Arc Pro B65 leads. It delivers 192.0 GPixel/s, which is 4.37 times the 43.92 GPixel/s of the B200 SXM6. This is consistent with the ROP count: 80 on the Arc Pro B65 versus 24 on the B200 SXM6. The Arc Pro B65 also has a much higher boost clock at 2400 MHz versus 1830 MHz, which helps in pixel-heavy workloads.

The memory capacity difference is also significant. The B200 SXM6 holds 180 GB, which is 5.63 times the 32 GB of the Arc Pro B65. This capacity allows the B200 SXM6 to hold larger models and datasets in memory without spilling to system RAM.

The power draw scales with performance. The B200 SXM6 has a TDP of 1000 W, which is 5 times the 200 W of the Arc Pro B65. The suggested PSU is 1400 W for the B200 SXM6 and 550 W for the Arc Pro B65.

Where Each One Wins

The NVIDIA B200 SXM6 wins decisively in compute throughput, memory bandwidth, memory capacity, and tensor core availability. Its 69.34 TFLOPS of FP32 and FP16 performance, combined with 8.19 TB/s of bandwidth and 180 GB of HBM3e, make it suited for server-side workloads such as large-scale AI inference, model training, and scientific computing. The 592 tensor cores provide dedicated hardware for matrix operations, which the Arc Pro B65 lacks entirely. The PCIe 6.0 x16 interface also gives the B200 SXM6 a newer bus standard for data transfer. Its release date of 2024-10-31 places it earlier in the market, and its predecessor and successor are both defined in the database, indicating an established product cycle.

The Intel Arc Pro B65 wins in graphics-oriented metrics. Its 192.0 GPixel/s pixel rate is 4.37 times higher than the B200 SXM6, and its 80 ROPs provide 3.33 times the raster output units. The Arc Pro B65 has 20 RT cores for ray tracing, a feature the B200 SXM6 does not list. The Arc Pro B65 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the B200 SXM6 lists no graphics API support. The Arc Pro B65 provides 4x DisplayPort 2.1 outputs, enabling direct display connectivity, whereas the B200 SXM6 has no display outputs. The Arc Pro B65 also has a much higher boost clock at 2400 MHz, which benefits latency-sensitive graphics workloads. Its power draw of 200 W is 5 times lower than the B200 SXM6, and it uses a standard dual-slot form factor with a single 8-pin connector, making it easier to integrate into workstation builds. The Arc Pro B65 was released on 2026-03-31, making it a newer product in the database.

For a user needing a graphics card with display outputs, ray tracing, and standard API support, the Arc Pro B65 is the applicable choice. For a user needing maximum compute throughput and memory capacity in a server module, the B200 SXM6 is the applicable choice. The data does not support using either product in the other's intended role.
